• How to change a function/formula in a whole column where I also have empty cells

  - by Zvi

  I have a column with a formula/function that has other cells as parameters. However in the column, every few rows I have a subtotal and blanks, for readability. Now I decided to change the formula/function but I can not do copy+paste on the whole column because of the subtotals/blank cells, and I can not do change+replace because there are parameters in the functions that uses other cells and thus it is different in each cell in the column. For example, if the formula is =if(A5>24,1,"") and I want to change it to =AA_userfn(A5,B5) Any idea how to change it easily? currently I copy+paste few rows at a time, but that is tedious. Maybe a Sub that will go all over the column (the column number as an input parameter) and looks for =if(, and then replaces it with =aa_userfn(Ax, By) where Ax and By are calculated based on the position of the cell currently changed in reference to the previous values in that cell. Any ideas will be welcomed

• Convert templated parameter type to string

  - by wheaties

  I've got a small bit of DRY going on in code I and others have written that I'd like to reduce but I'm failing to figure out how to get it done. This is legacy COM code but it's interfering with the readability. I'd like to do the following: bool queryInterface<class T, class V>(T &_input, V &_output, Logger &_logger){ if( FAILED( _input->QueryInterface( &_output ) ) ){ _logger.error() << "Failed to Query Interface between " << MAGICHAPPENS<T>() << " and " << MAGICHAPPENS<V>(); return false; } if( _output == NULL ){ _logger.warn() << "Unable to Query Interface between " << MAGICHAPPENS<T>() << " and " << MAGICHAPPENS<V>(); return false; } } Wherein the "MAGICHAPPENS()" function would spit out the name of the variable type. Such that if "V" were a IQueryFilter I'd get back a string of "IQueryFilter." I can't think of any reasonable solution without having to write a bunch of template specializations totally defeating the point in the first place. Is there a way to write ANDMAGICHAPPENS?

• SQL Server Compact timed out waiting for a lock

  - by jankhana

  Hi all, I'm having an application in that i use Sql Compact 3.5 with VS2008. I'm running multiple threads in my application which contacts the compact database and accesses the row. It selects and deletes those rows in a fashion i.e selecting and giving to the application 5 rows and deleting those rows from the table. It works great with a single thread but if i use multiple threads i.e if 3 or more threads are running I get very often the TimeOut Error!!! I have increased the Time out property in the connection string but it didn't give me expected result. The error log is as follow: SQL Server Compact timed out waiting for a lock. The default lock time is 2000ms for devices and 5000ms for desktops. The default lock timeout can be increased in the connection string using the ssce: default lock timeout property. [ Session id = 5,Thread id = 4204,Process id = 4808,Table name = XXX,Conflict type = x lock (s blocks),Resource = TAB ] The Query that I use to retrieve is as follows: " select Top(5) * from TableName order by id; delete from TableName where id in(select top(5) id from TableName order by id); " Is there any way by which we can avoid this Time Out exception??????? The above query I un as a transaction in VS2008 one using SQLCECommand and the other using SqlCEDataAdapter. Any Idea!!!!!! Reply

• sending a selected value from a dropdownlist to a servlet with xhr

  - by kawtousse

  I am trying to send the clicked value of a dropdown list to my servlet to run a SQL query using the value received. To do it I am using Ajax like that: function showProject(prj) { xmlhttp = GetXmlHttpObject(); if (xmlhttp == null) { alert ("Browser does not support HTTP Request"); return; } var url = "ServletxmlGenerator.java"; idprj = prj.options[prj.selectedIndex].value; url = url + "?idprj=" + idprj; xmlhttp.onreadystatechange = stateChanged; xmlhttp.open("GET",url,true); xmlhttp.send(null); } The servlet when String projectcode=(String) request.getParameter("idprj"); returns null. When I select a value from the JSP that construct the dropdown list and from which the function showProject is handled the same thing is happned. It returns always null. So the parameter(idprj) is not passed anyway. How can I handle with this. I need to send the selected value to the servlet to run my SQL query.

• MySQL Cursor Issue

  - by James Inman

  I've got the following code - this is the first time I've really attempted using cursors. DELIMITER $$ DROP PROCEDURE IF EXISTS demo$$ DROP TABLE IF EXISTS temp$$ CREATE TEMPORARY TABLE temp( id INTEGER NOT NULL AUTO_INCREMENT, start DATETIME NOT NULL, end DATETIME NOT NULL, PRIMARY KEY(id) ) $$ CREATE PROCEDURE demo() BEGIN DECLARE done INT DEFAULT 0; DECLARE a, b DATETIME; DECLARE cur1 CURSOR FOR SELECT MAX(end) AS end FROM ( SELECT id, start, end, @r := @r + (start > @edate) AS num, @edate := GREATEST(@edate, end) FROM ( SELECT @r := 0, @edate := '0001-01-01' ) vars, student_lectures WHERE ( student_id = 1 AND start >= '2010-04-26 00:00:00' AND end <= '2010-04-30 23:59:59' ) ORDER BY start ) q GROUP BY num; DECLARE cur2 CURSOR FOR SELECT MIN(start) AS start FROM ( SELECT id, start, end, @r := @r + (start > @edate) AS num, @edate := GREATEST(@edate, end) FROM ( SELECT @r := 0, @edate := '0001-01-01' ) vars, student_lectures WHERE ( student_id = 1 AND start >= '2010-04-26 00:00:00' AND end <= '2010-04-30 23:59:59' ) ORDER BY start ) q GROUP BY num LIMIT 1, 18446744073709551615; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; OPEN cur1; OPEN cur2; REPEAT FETCH cur1 INTO a; FETCH cur2 INTO b; IF NOT done THEN INSERT INTO temp(start, end) VALUES(a,b); END IF; UNTIL done END REPEAT; CLOSE cur1; CLOSE cur2; END $$ SELECT * FROM temp; I'm not getting anything outputted into the temp table.

• IPhone SDK - Leaking Memory with performSelectorInBackground

  - by Steblo

  Hi. Maybe someone can help me with this strange thing: If a user clicks on a button, a new UITableView is pushed to the navigation controller. This new view is doing some database querying which takes some time. Therefore I wanted to do the loading in background. What works WITHOUT leaking memory (but freezes the screen until everything is done): WorkController *tmp=[[WorkController alloc] initWithStyle:UITableViewStyleGrouped]; self.workController=tmp; [tmp release]; [self.workController loadList]; // Does the DB Query [self.workController pushViewController:self.workController animated:YES]; Now I tried to do this: // Show Wait indicator .... WorkController *tmp=[[WorkController alloc] initWithStyle:UITableViewStyleGrouped]; self.workController=tmp; [tmp release]; [self performSelectorInBackground:@selector(getController) withObject:nil]; } -(void) getController { [self.workController loadList]; // Does the DB Query [self.navigationController pushViewController:self.workController animated:YES]; } This also works but is leaking memory and I don't know why ! Can you help ? By the way - is it possible for an App to get into AppStore with a small memory leak ? Or will this be checked first of all ? Thanks in advance !

• NHibernate IQueryable Collection as Property of Root

  - by Khalid Abuhakmeh

  Hello and thank you for taking the time to read this. I have a root object that has a property that is a collection. For example : I have a Shelf object that has Books. // now public class Shelf { public ICollection<Book> Books {get; set;} } // want public class Shelf { public IQueryable<Book> Books {get;set;} } What I want to accomplish is to return a collection that is IQueryable so that I can run paging and filtering off of the collection directly from the the parent. var shelf = shelfRepository.Get(1); var filtered = from book in shelf.Books where book.Name == "The Great Gatsby" select book; I want to have that query executed specifically by NHibernate and not a get all to load a whole collection and then parse it in memory (which is what currently happens when I use ICollection). The reasoning behind this is that my collection could be huge, tens of thousands of records, and a get all query could bash my database. I would like to do this implicitly so that when NHibernate sees and IQueryable on my class it knows what to do. I have looked at NHibernates Linq provider and currently I am making the decision to take large collections and split them into their own repository so that I can make explicit calls for filtering and paging. Linq To SQL offers something similar to what I'm talking about.

• VBA nested Loop flow control

  - by PCGIZMO

  I will be brief and stick to what I know. This code for the most part works as it should. The only issue is in the iteration of the x and z loop. these to loops should set the range and yLABEL for the Y loop. I can get through a set and come up with the correct range after that things go bonkers. I know some of it has to do with not breaking out of x to set z and then back to x update the range. It should work z is found then x. the range between them is set for y. then next x but y stays then rang between y and x is set for y.. so on and so forth kinda like a slinky down the stairs. or a slide rule depending on how I set the loops either way I end up all over the place after a couple iterations. I have done a few things but each time I break out of x to set z , X restarts at the top of the range. At least that's what I think I am seeing. In the example sheet i have since changed the way the way the offset works with the loop but the idea is still the same. I have goto statements at this time i was going to try figuring out conditional switches after the loops were working. Any help direction or advice is appreciated.

• Tool for generating flat files from SQL objects dynamically

  - by Fabio Gouw

  Hello! I'm looking for a tool or component that generates flat files given a SQL Server's query result (from a stored procedure or a SELECT * over a table or view). This will be a batch process which runs every day, and every day a new file is created. I could use SQL Server Integration Services (DTS), but I have a mandatory requirement: the output of the file need to be dynamic. If a new column is added in my query result, the file must have this new column too, without having to modify my SSIS package. If a column is removed, then the flat file no longer will have it. I’ve tried to do this with SSIS, but when I create a new package I need to specify the number of columns. Another requirement is configuring the format of the output, depending on the data type of the column. If it’s a datetime, the format needs to be YYYY-MM-DD. If it’s a float, then I need to use 2 decimal digits, and so on. Does anyone know a tool that does this job? Thanks

• Why TVs are costlier than Monitor for same screen size?

  - by Vikrant Chaudhary

  Just wondering, why LCD/LED-backlit TVs cost more (almost double) than LCD/LED-backlit monitors for same screen size. Because I guess that TVs and Monitors, both use almost same technologies and both nowadays support some common connectors (HDMI/D-Sub/DVI etc). And since a Monitor has much higher resolution than a TV for that size, and they are used more closely than TVs, Monitors probably require more engineering effort. So, Monitors are supposed to be costlier than TVs, right? Ex: A ViewSonic (or any) 22"/26" monitor supports Full-HD resolution at 1080p (WSXGA+-1680×1050, WUXGA-1920×1200), while all 22"/26" HDTVs support HD-ready 720p (WXGA-1366x768) only, which is also the resolution of my Notebook's 15.6" screen.

• SQL Server 2005, wide indexes, computed columns, and sargable queries

  - by luksan

  In my database, assume we have a table defined as follows: CREATE TABLE [Chemical]( [ChemicalId] int NOT NULL IDENTITY(1,1) PRIMARY KEY, [Name] nvarchar(max) NOT NULL, [Description] nvarchar(max) NULL ) The value for Name can be very large, so we must use nvarchar(max). Unfortunately, we want to create an index on this column, but nvarchar(max) is not supported inside an index. So we create the following computed column and associated index based upon it: ALTER TABLE [Chemical] ADD [Name_Indexable] AS LEFT([Name], 20) CREATE INDEX [IX_Name] ON [Chemical]([Name_Indexable]) INCLUDE([Name]) The index will not be unique but we can enforce uniqueness via a trigger. If we perform the following query, the execution plan results in a index scan, which is not what we want: SELECT [ChemicalId], [Name], [Description] FROM [Chemical] WHERE [Name]='[1,1''-Bicyclohexyl]-2-carboxylic acid, 4'',5-dihydroxy-2'',3-dimethyl-5'',6-bis[(1-oxo-2-propen-1-yl)oxy]-, methyl ester' However, if we modify the query to make it "sargable," then the execution plan results in an index seek, which is what we want: SELECT [ChemicalId], [Name], [Description] FROM [Chemical] WHERE [Indexable_Name]='[1,1''-Bicyclohexyl]-' AND [Name]='[1,1''-Bicyclohexyl]-2-carboxylic acid, 4'',5-dihydroxy-2'',3-dimethyl-5'',6-bis[(1-oxo-2-propen-1-yl)oxy]-, methyl ester' Is this a good solution if we control the format of all queries executed against the database via our middle tier? Is there a better way? Is this a major kludge? Should we be using full-text indexing?

• Return and Save XML Object From Sharepoint List Web Service

  - by HurnsMobile

  I am trying to populate a variable with an XML response from an ajax call on page load so that on keyup I can filter through that list without making repeated get requests (think very rudimentary autocomplete). The trouble that I am having seems to be potentially related to variable scoping but I am fairly new to js/jQuery so I am not quite certain. The following code doesn't do anything on key up and adding alerts to it tells me that it is executing leadResults() on keyup and that the variable is returning an XML response object but it appears to be empty. The strange bit is that if I move the leadResults() call into the getResults() function the UL is populated with the results correctly. Im beating my head against the wall on this one, please help! var resultsXml; $(document).ready( function() { var leadLookupCaml = "<Query> \ <Where> \ <Eq> \ <FieldRef Name=\"Lead_x0020_Status\"/> \ <Value Type=\"Text\">Active</Value> \ </Eq> \ </Where> \ </Query>" $().SPServices({ operation: "GetListItems", webURL: "http://sharepoint/departments/sales", listName: "Leads", CAMLQuery: leadLookupCaml, CAMLRowLimit: 0, completefunc: getResults }); }) $("#lead_search").keyup( function(e) { leadResults(); }) function getResults(xData, status) { resultsXml = xData; } function leadResults() { xData = resultsXml; $("#lead_results li").remove(); $(xData.responseXML).find("z\\:row").each(function() { var selectHtml = "<li>" + "<a href=\"http://sharepoint/departments/sales/Lists/Lead%20Groups/DispForm.aspx?ID=" + $(this).attr("ows_ID") + ">" + $(this).attr("ows_Title")+" : " + $(this).attr("ows_Phone") + "</a>\ </li>"; $("#lead_results").append(selectHtml); }); }

• how do i filter my lucene search results?

  - by Andrew Bullock

  Say my requirement is "search for all users by name, who are over 18" If i were using SQL, i might write something like: Select * from [Users] Where ([firstname] like '%' + @searchTerm + '%' OR [lastname] like '%' + @searchTerm + '%') AND [age] >= 18 However, im having difficulty translating this into lucene.net. This is what i have so far: var parser = new MultiFieldQueryParser({ "firstname", "lastname"}, new StandardAnalyser()); var luceneQuery = parser.Parse(searchterm) var query = FullTextSession.CreateFullTextQuery(luceneQuery, typeof(User)); var results = query.List<User>(); How do i add in the "where age = 18" bit? I've heard about .SetFilter(), but this only accepts LuceneQueries, and not IQueries. If SetFilter is the right thing to use, how do I make the appropriate filter? If not, what do I use and how do i do it? Thanks! P.S. This is a vastly simplified version of what I'm trying to do for clarity, my WHERE clause is actually a lot more complicated than shown here. In reality i need to check if ids exist in subqueries and check a number of unindexed properties. Any solutions given need to support this. Thanks

• Target line parameters for shortcuts in Windows Explorer?

  - by Charles E. Gates Jr.

  I am using Windows 7 and I am looking for a list of the different parameters to use in the Target line of a shortcut in Windows Explorer. For example: /n forces it to open a new window, even if it duplicates a window that is already open. /e uses Windows Explorer view (multi-paned) /root,X restricts Explorer to showing only the contents of file folder X (and its sub-folders) /select,Y automatically selects Y (either a file or folder). What other parameters exist? I have been searching online and cannot find anything.

• how to get the real bounds with google maps when fully zoomed out

  - by brad

  I have a map that shows location points based on the gbounds of the map. For example, any time the map is moved/zoomed, i find the bounds and query for locations that fall within those bounds. Unfortunately I'm unable to display all my locations when fully zoomed out. Reason being, gmaps reports the min/max long as whatever is at the edge of the map, but if you zoom out enough, you can get a longitudinal range that excludes visible locations. For instance, if you zoom your map so that you see NorthAmerica twice, on the far left and far right. The min/max long are around: -36.5625 to 170.15625. But this almost completely excludes NorthAmerica which lies in the -180 to -60 range. Obviously this is bothersome as you can actually see the continent NorthAmerica (twice), but when I query my for locations in the range from google maps, NorthAmerica isn't returned. My code for finding the min/max long is: bounds = gmap.getBounds(); min_lat = bounds.getSouthWest().lat() max_lat = bounds.getNorthEast().lat() Has anyone encountered this and can anyone suggest a workaround? Off the top of my head I can only thing of a hack: to check the zoom level and hardcode the min/max lats to -180/180 if necessary, which is definitely unacceptable.

• Drupal 6 node_view empty

  I'm trying to produce a page with a list of specific nodes but the node_view returns an empty string. This is my query: function events_upcoming() { $output = ''; $has_events = false; $res = pager_query(db_rewrite_sql("SELECT n.nid, n.created FROM {node} n WHERE n.type = 'events' AND n.status = 1 ORDER BY n.sticky DESC, n.created DESC"), variable_get('default_nodes_main', 10)); while ($n = db_fetch_object($res)) { $output .= node_view(node_load($n->nid), 1); $has_events = true; } if ($has_events) { $output .= theme('pager', NULL, variable_get('default_nodes_main', 10)); } return $output; } hook_menu (part of): 'events/upcoming' => array( 'title' => t('Upcoming Events'), 'page callback' => 'events_upcoming', 'access arguments' => array('access content'), 'type' => MENU_SUGGESTED_ITEM ), the implementation of hook_view: function events_view($node, $teaser = false, $page = false) { $node = node_prepare($node, $teaser); if ($page) { // TODO: Handle breadcrump } return $node; } now, if I add a var_dump($node) inside events_view the node is present and I can see the values I want, and if I add a var_dump inside while loop in events_upcoming I also get a node id from the query. the strange thing is, when I load localhost/events/upcoming I see the pager and nothing else. I have used the blog.module as a reference, but what am I missing here?

• Remote Desktop Services Gateway Issue

  - by AVandelay05

  Alright fellow techies here's the rundown. I have installed Server 2008 r2 Remote Dekstop Services on a VM in my network. I installed the following RD role services: RD Session Host, Licensing, Connection Broker, Gateway, Web Access. When I set things up originally, the gateway server and RDWeb worked as it should locally. After getting things running locally (remoteserver.domainname.local) I wanted to test things externally. From the outside, I couldn't get things running (meaning I could connect to rdweb access externally, but when I tried to run an app I would get the message "can't connect/find computer"). Here's my setup for external access The VM has every RD Services role services installed on it, meaning it acts as gateway, rd web access, session host, licensing, the whole bit. I made a self-signed certificate on the gateway server (gateway.domainname.net is the cert name). Internally, I have a secondary forward-lookup zone called domainname.net with an A record gateway pointing to the local IP of the gateway server. On our public DNS (domainname.net) I have an A record gateway. This is to access the RDWeb externally. In IIS I have the following authentication settings RDWeb: All disabled except for anonymous authentication Rpc: All disabled except for basic and windows RpcWithCert: All disbled except for windows authentication I have the necessary web access config in our sonicwall tz210 (https and rdp, external ip pointing to local ip of rds server) RAP and CAP have the correct user and computer groups, authentication, and allowed devices After all of this, here's what happens accessing externally. I can login correctly to RDWeb Access (I've tried a bogus login, I can't login to it so that's working properly). I see the Apps for use. I click on an app, click connect, the credential window opens, I put in the correct user creds, it tries to connect to the gateway server, but then the cred window comes back in view. I tried to reach a limit of failed logins, but never reached one, haha. So from the same external client machine I try to connect to the gateway through a Remote Desktop connection. I put in the correct gateway settings in the RD window, try to connect and get the same results as I did in RDWeb access. I checked the event logs on the RD Services machine and saw the following event IDs around the time I tried to login externally: ID 6037 with the message "The program svchost.exe, with the assigned process ID 2168, could not authenticate locally by using the target name host/gateway.domainname.net. The target name used is not valid. A target name should refer to one of the local computer names, for example, the DNS host name. Try a different target name." ID 10 RADWebAccess "RD Web Access was unable to access gateway.domainname.net, which is the server that is specified as running the RemoteApp and Desktop Connection Management service.

I don't think the VM has a null SID. The SID of the VM and it's physical host have different SIDS. I can access the blank page for rpc externally using the external gateway name. It seems like authentication is a problem. Also, is it a problem that the external name of the gateway server doesn't match the local name? The external name (which the cert is based on) is gateway.domainname.net and the internal name is remoteserver.domainname.local. That's the only thing I can think of that would be the problem, but the external name has to be different from the local right? Internally, I ping gateway.domainname.net and it gives me the correct local IP of the server. Now, there isn't an actual computer name in AD, but I don't know how I would achieve that? I hope I've been clear....any help would be appreciated. I think I'm close to achieving this. :)

• Apache + LDAP Auth: access to / failed, reason: require directives present and no Authoritative hand

  - by Karolis T.

  Can't solve this one, here's my .htaccess: AuthPAM_Enabled Off AuthType Basic AuthBasicProvider ldap AuthzLDAPAuthoritative on AuthName "MESSAGE" Require ldap-group cn=CHANGED, cn=CHANGED AuthLDAPURL "ldap://localhost/dc=CHANGED,dc=CHANGED?uid?sub?(objectClass=posixAccount)" AuthLDAPBindDN CHANGED AuthLDAPBindPassword CHANGED AuthLDAPGroupAttribute memberUid AuthLDAPURL is correct, BindDN and BindPassword are correct also (verified with ldapvi -D ..). Apache version: Apache/2.2.9 (Debian) The error message seems cryptic to me, I have AuthzLDAPAuthoritative on so where's the problem. EDIT: LDAP modules are loaded, the problem is not with them being missing. # ls /etc/apache2/mods-enabled/*ldap* /etc/apache2/mods-enabled/authnz_ldap.load /etc/apache2/mods-enabled/ldap.load EDIT2: Solved it by changing funky Require ldap-group cn=CHANGED, cn=CHANGED line with Require valid-user Since AuthzLDAPAuthoritative is on, no other auth methods will be used and valid-user requirement will auth via LDAP. (right? :/)

• using LocalAsyncVclCall in Delphi

  - by Salvador

  Actually i am using the AsyncCalls library to execute an Query asynchronously in this way. while AsyncMultiSync([RunQuery], True, 10) = WAIT_TIMEOUT do begin FrmProgress.refresh; //Update the ellapsed time in a popup form Application.ProcessMessages; end; and everything works ok. Now i want to do the same for load the query in a grid. so i tried this while LocalAsyncVclCall(@InitGrid, 10) = WAIT_TIMEOUT do begin FrmProgress.refresh; Application.ProcessMessages; end; but obviously not compile because the type returned by LocalAsyncVclCall is IAsyncCall and not a Cardinal. also i tried this, but not works. while not LocalAsyncVclCall(@InitGrid, 10).Finished do begin FrmProgress.refresh; Application.ProcessMessages; end; How i can use LocalAsyncVclCall or another function to execute an VCL code asynchronously . i want something like this. while ExecuteMyVCLProcedure(@InitGrid) = WAIT_TIMEOUT do begin FrmProgress.refresh; Application.ProcessMessages; end; Thanks in advance.

• Choosing the right web service

  - by Ratan Sharma

  My website currently working in ASP.NET 1.1 Old Process In our database we have huge amount of data stored for a decoding purpose. We have to update this huge set of data table each week(Data is supplied from a vendor). In our website (in asp.net 1.1) we query our database to decode information. New process Now instead of storing data in our database and query them, we want to replace this through the web service, AS now the vendor is supplying us a DLL, which will give us the decoded information. Information on the DLL provided by the vendor The DLL provided, can only be added in 4.0 sites. SO that also impleies that i can not directly add the dll to my 1.1 site. This DLL is exposing certain methods, we simply have to add the DLL refernce in our web service and call the method and fetch the needed information. Thus we will not have to store those information in our database. So which type of web service I should go for (asmx OR WCF) that will use the DLLs provided by vendor to fetch the decoded information ?? Flexibility i am looking for in the web service are: It can be consumed from asp.net 1.1 site directly and also using jQuery ajax. It can be consumed from other web services running on the server. It can be consumed from some windows services running from the server. NOTE : Moreover we have a plan to migrate our website from asp.net 1.1 to 4.0 version in future.So it should be that much supportive for future upgrade.

• SSIS - How do I use a resultset as input in a SQL task and get data types right?

  - by thursdaysgeek

  I am trying to merge records from an Oracle database table to my local SQL table. I have a variable for the package that is an Object, called OWell. I have a data flow task that gets the Oracle data as a SQL statment (select well_id, well_name from OWell order by Well_ID), and then a conversion task to convert well_id from a DT_STR of length 15 to a DT_WSTR; and convert well_name from a DT_STR of length 15 to DT_WSTR of length 50. That is then stored in the recordset OWell. The reason for the conversions is the table that I want to add records to has an identity field: SSIS shows well_id as a DT_WSTR of length 15, well_name a DT_WSTR of length 50. I then have a SQL task that connects to the local database and attempts to add records that are not there yet. I've tried various things: using the OWell as a result set and referring to it in my SQL statement. Currently, I have the ResultSet set to None, and the following SQL statment: Insert into WELL (WELL_ID, WELL_NAME) Select OWELL_ID, OWELL_NAME from OWell where OWELL_ID not in (select WELL.WELL_ID from WELL) For Parameter Mapping, I have Paramater 0, called OWell_ID, from my variable User::OWell. Parameter 1, called OWell_Name is from the same variable. Both are set to VARCHAR, although I've also tried NVARCHAR. I do not have a Result set. I am getting the following error: Error: 0xC002F210 at Insert records to FLEDG, Execute SQL Task: Executing the query "Insert into WELL (WELL_ID, WELL_NAME) Select OWELL..." failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_STR)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. I don't think it's a data type issue, but rather that I somehow am not using the resultset properly. How, exactly, am I supposed to refer to that recordset in my SQL task, so that I can use the two recordset fields and add records that are missing?

• how do i execute a stored procedure with vici coolstorage?

  - by lincolnk

  I'm building an app around Vici Coolstorage (asp.net version). I have my classes created and mapped to my database tables and can pull a list of all records fine. I've written a stored procedure where the query jumps across databases that aren't mapped with Coolstorage, however, the fields in the query result map directly to one of my classes. The procedure takes 1 parameter. so 2 questions here: how do i execute the stored procedure? i'm doing this CSParameterCollection collection = new CSParameterCollection(); collection.Add("@id", id); var result = Vici.CoolStorage.CSDatabase.RunQuery("procedurename", collection); and getting the exception "Incorrect syntax near 'procedurename'." (i'm guessing this is because it's trying to execute it as text rather than a procedure?) and also, since the class representing my table is defined as abstract, how do i specify that result should create a list of MyTable objects instead of generic or dynamic or whatever objects? if i try Vici.CoolStorage.CSDatabase.RunQuery<MyTable>(...) the compiler yells at me for it being an abstract class.

• How to create a list of data clickable? asp.net

  - by Roger Filipe

  Hello, I am learning asp.net but I'm finding some problems. My doubt is how to make a list of titles of news contained in a database. And in this list, each of the titles when clicked is redirected to a page where you will be able to view the news in full (Title, Body, Author ..). What I got: - A database containing a table with the news, every news is associated with an identification code (ex: "ID"). - A page where you will make the listing. (Ex: site / listofnews.aspx) - I have a page that uses the method "querystring" to know what is the primarykey the news. (Ex: site/shownews.aspx?ID=12345, where "12345" is the primarykey of the news. Once it knows what is the primarykey of the news in the database, it loads each of the fields of the page (news.aspx) with the news, this part is working ok. - The data is retrieve using the Linq, so I receive a List of "News", the class "News" as ID, Title, Body, Author.. My doubt is how to make the listing clickable. In php I used this method (make a list of html links, in each link the href field is changed so that the tag "id" coincides with the news): //database used is oracle, $stmt is the query, you don´t need to understand how it works. oci_define_by_name($stmt, "ID", $id); oci_define_by_name($stmt, "TITLE", $title); if (!oci_execute($stmt, OCI_DEFAULT)) { $err = oci_error($stmt); trigger_error('Query failed: ' . $err['message'], E_USER_ERROR); } echo '<br />'; while (oci_fetch($stmt)) {<------While there is data from the database , create links $link = '<a href="site/shownews.php?ID='.$id.'" >'.$title.'</a>';<----the shownews.php?ID= $id, creates the link according with the ID echo $link<---Prints the link echo '<br />'; } How do i make the same with asp.net?
