  • C# to VB conversion query

    - by Jim
    This C# code successfully gets the 2 relevant records into _currentUserRegisteredEventIds: ctx.FetchEventsForWhichCurrentUserIsRegistered((op) => { if (!op.HasError) { var items = op.Value; _currentUserRegisteredEventIds = new HashSet<int>(items); UpdateRegistrationButtons(); } }, null); but VB code trying to do the same thing has nothing in _currentUserRegisteredEventIds: ctx.FetchEventsForWhichCurrentUserIsRegistered(Function(op) If Not op.HasError Then Dim items = op.Value _currentUserRegisteredEventIds = New HashSet(Of Integer)(items) UpdateRegistrationButtons() End If Any help appreciated.

  • AppEngine JDO-QL : Problem with multiple AND and OR in query

    - by KlasE
    Hi, I'm working with App Engine(Java/JDO) and are trying to do some querying with lists. So I have the following class: @PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true") public class MyEntity { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) Key key; @Persistent List<String> tags = new ArrayList<String>(); @Persistent String otherVar; } The following JDO-QL works for me: ( tags.contains('a') || tags.contains('b') || tags.contains('c') || tags.contains('d') ) && otherVar > 'a' && otherVar < 'z' This seem to return all results where tags has one or more strings with one or more of the given values and together with the inequality search on otherVar But the following do not work: (tags.contains('a') || tags.contains('_a')) && (tags.contains('b') || tags.contains('_b')) && otherVar > 'a' && otherVar < 'z' In this case I want all hits where there is at least one a (either a or _a) and one b (either b or _b) together with the inequality search as before. But the problem is that I also get back the results where there is a but no b, which is not what I want. Maybe I have missed something obvious, or done a coding error, or possibly there is a restriction on how you can write these queries in appengine, so any tips or help would be very welcome. Regards Klas

  • Convert query with system objects from SQL 2000 to 2005/2008

    - by Dan
    I have some SQL I need to get working on SQL 2005/2008. The SQL is from SQL 2000 and uses some system objects to make it work. master.dbo.spt_provider_types master.dbo.syscharsets systypes syscolumns sysobjects I know SQL 2005 does no longer use system tables and I can get the same information from views, but I am looking for a solution that will work for both SQL 2000 and 2005/2008. Any ideas? select top 100 percent TABLE_CATALOG = db_name(), TABLE_SCHEMA = user_name(o.uid), TABLE_NAME = o.name, COLUMN_NAME = c.name, ORDINAL_POSITION = convert(int, ( select count(*) from syscolumns sc where sc.id = c.id AND sc.number = c.number AND sc.colid <= c.colid )), IS_COMPUTED = convert(bit, c.iscomputed) from syscolumns c left join syscomments m on c.cdefault = m.id and m.colid = 1, sysobjects o, master.dbo.spt_provider_types d, systypes t, master.dbo.syscharsets a_cha /* charset/1001, not sortorder.*/ where o.name = @table_name and permissions(o.id, c.name) <> 0 and (o.type in ('U','V','S') OR (o.type in ('TF', 'IF') and c.number = 0)) and o.id = c.id and t.xtype = d.ss_dtype and c.length = case when d.fixlen > 0 then d.fixlen else c.length end and c.xusertype = t.xusertype and a_cha.type = 1001 /* type is charset */ and a_cha.id = isnull(convert(tinyint, CollationPropertyFromID(c.collationid, 'sqlcharset')), convert(tinyint, ServerProperty('sqlcharset'))) -- make sure there's one and only one row selected for each column order by 2, 3, c.colorder ) tbl where IS_COMPUTED = 0

  • Apache URL rewrite query

    - by ant-1980
    Can anyone tell me how to do this? i'm stumped! I need a modified URL in this format this55-is-a-test-id-23.html But I need the 23 as a GET. I can't rely on searching for 'id' as this may occur elsewhere in the URL. Is there any way of searching for the last occurrence of id and passing that as a get using an Apache RewriteRule in .htaccess?? Many thanks Ant

  • Query MySQL data from Excel (or vice-versa)

    - by Charles
    I'm trying to automate a tedious problem. I get large Excel (.xls or .csv, whatever's more convenient) files with lists of people. I want to compare these against my MySQL database.* At the moment I'm exporting MySQL tables and reading them from an Excel spreadsheet. At that point it's not difficult to use =LOOKUP() and such commands to do the work I need, and of course the various text processing I need to do is easy enough to do in Excel. But I can't help but think that this is more work than it needs to be. Is there some way to get at the MySQL data directly from Excel? Alternately, is there a way I could access a reasonably large (~10k records) csv file in a sql script? This seems to be rather basic, but I haven't managed to make it work so far. I found an ODBC connection for MySQL but that doesn't seem to do what I need. In particular, I'm testing whether the name matches or whether any of four email addresses match. I also return information on what matched for the benefit of the next person to use the data, something like "Name 'Bob Smith' not found, but 'Robert Smith' matches on email address robert.smith@foo".

  • Problems with inheritance query view and one to many association in entity framework 4

    - by Kazys
    Hi, I have situation in with I stucked and don't know way out. The problem is in my bigger model, but I have made small example which shows the same problem. I have 4 tables. I called them SuperParent, NamedParent, TypedParent and ParentType. NamedParent and TypedParent derives from superParent. TypedParent has one to many association with ParentType. I describe mapping for entities using queryView. The problem is then I want to get TypedParents and Include ParentType I get the following exception: An error occurred while preparing the command definition. See the inner exception for details. --- System.ArgumentException: The ResultType of the specified expression is not compatible with the required type. The expression ResultType is 'Transient.reference[PasibandymaiModel.SuperParent]' but the required type is 'Transient.reference[PasibandymaiModel.TypedParent]'.

  • SQL Query - Need some basic help

    - by Chuck Folds
    I'm in need of some basic TSQL help. Here's my table layout: Orders Table SSN ZipCode ZipLookup Table ZipCode State All columns are varchars. How would I get a list of States with the number of distinct SSN's in each state? Preferably, if a particular SSN has orders from multiple states only the state with the most orders would be counted for that SSN. Thank you for any tips you can give me.

  • JQuery UI Dialog query dialog DOM

    - by Travis
    The following simply loads a jquery-ui dialog from an external html file. $('#showdialog').click(function(e) { var div = $('<div>loading...</div>'); div.dialog({ modal: true, open: function() { div.load('anotherpage.html'); } }); e.preventDefault(); }); After the DOM loads from the external html file, I'd like to interrogate it with JQuery. For example, supposing anothorpage.html had a bunch of anchors on it, I'd like to wire up click handlers for them when it loads into the dialog. Any ideas?

  • How to manually query LDAP through Acegi's beans?

    - by Veggen Skrikk
    I have an application using Acegi (earlier version of Spring Security) and LDAP for logins. Now, a specific scenario requires me to discover user's LDAP groups at arbitrary time (not at login time). Is it possible to use already set up Acegi to handle this situation? I'm thinking of using the configured LdapAuthProvider (or LdapAuthPopulator or whatever's appropriate) to get all the groups associated with a given username. Is this possible? If yes, please, please, give some hints how it should be done...

  • How to export SQL Server 2005 query to CSV

    - by jmgant
    I want to export some SQL Server 2005 data to CSV format (comma-separated with quotes). I can think of a lot of complicated ways to do it, but I want to do it the right way. I've looked at bcp, but I can't figure out how to put the quotes around the fields (except concatenating them to the field values, which is ugly). I guess I could do it with sqlcmd and -o, but that seems ugly for the same reason. Is there a bcp way to do it? Is there a reasonable sqlcmd way to do it? Is there some great, simple utility built into the Management Studio that I'm just overlooking?

  • SQL Query in Ruby: Only select the changes

    - by JJ Liu
    Suppose I have a table (PriceHistory) like this, every time I change anything in the row, I will record the whole row again in the table. id | buy_price | sell_price | change_date 1 | 2 | 2 | 2012-06-22 2 | 3 | 2 | 2012-06-20 3 | 2 | 6 | 2012-06-15 4 | 5 | 5 | 2012-06-15 5 | 5 | 7 | 2012-06-15 6 | 4 | 8 | 2012-06-12 I only care about the change of BuyPrice, Is there a way to just select row 1, 2, 3, & 5? Here is the Ruby code I come up with, but it does not only select the changed rows PriceHistory.select("id, BuyPrice, change_date"). order("change_date DESC") Both Ruby and SQL answers are fine.

  • Entity Framework - avoiding another query

    - by adamjellyit
    I have a requirement to only save data to a table in a database (I don't need to read it) If the record already exists I want to update it otherwise I will add it. It usually exists. My entity context might already hold the object .. if it does I want to find it and use it again without causing it to refresh from the database when I 'find' it i.e. The context holds a collection of entities (rows of a database) I want to find an entity in the collection and only want the context to go to the database if entity is not in the collection. I don't care about the current values of the entity .. I just want to update them. Hope this is clear ..... thanks

(Acquiring AD OU list & Active Directory list OU's) were my previous Q's. string defaultNamingContext; //TODO 0 - Acquire and display the available OU's DirectoryEntry rootDSE = new DirectoryEntry("LDAP://RootDSE"); defaultNamingContext = rootDSE.Properties["defaultNamingContext"].Value.ToString(); DirectoryEntry entryToQuery = new DirectoryEntry ("LDAP://" + defaultNamingContext); MessageBox.Show(entryToQuery.Path.ToString()); DirectorySearcher ouSearch = new DirectorySearcher(entryToQuery.Path); ouSearch.Filter = "(objectCatergory=organizationalUnit)"; ouSearch.SearchScope = SearchScope.Subtree; ouSearch.PropertiesToLoad.Add("name"); SearchResultCollection allOUS = ouSearch.FindAll(); foreach (SearchResult oneResult in allOUS) { //comboBox1.Items.Add(oneResult.ToString()); comboBox1.Items.Add(oneResult.Properties["name"][0]); } I have been through and debugged everything i know, the searcher isn't picking up any results, hence why nothing is populated in the combo box.

    - by pg
    http://www.chuckecheese.com/rotator.php?cheese=4&id=1 I want to take out the id, leaving the cheese to stand alone. I tried: $qs = preg_replace("[^&id=*]" ,'',$_SERVER[QUERY_STRING]); But that said I was using an improper modifier. I want to remove "$id=" and whatever number comes after it. Are regexp really as hard as they seem for me?

  • Oracle EXECUTE IMMEDIATE changes explain plan of query.

    - by Gunny
    I have a stored procedure that I am calling using EXECUTE IMMEDIATE. The issue that I am facing is that the explain plan is different when I call the procedure directly vs when I use EXECUTE IMMEDIATE to call the procedure. This is causing the execution time to increase 5x. The main difference between the plans is that when I use execute immediate the optimizer isn't unnesting the subquery (I'm using a NOT EXISTS condition). We are using Rule Based Optimizer here at work. Example: Fast: begin package.procedure; end; / Slow: begin execute immediate 'begin package.' || proc_name || '; end;'; end; /
