  • 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.

  • Linq Getting Customers group by date and then by their type

    - by Nitin varpe
    I am working on generating report for showing customer using LINQ in C#. I want to show no. of customers of each type. There are 3 types of customer registered, guest and manager. I want to group by customers by registered date and then by type of customer. i.e If today 3 guest, 4 registered and 2 manager are inserted. and tomorrow 4,5 and 6 are registered resp. then report should show Number of customers registerd on the day . separate row for each type. DATE TYPEOF CUSTOMER COUNT 31-10-2013 GUEST 3 31-10-2013 REGISTERED 4 31-10-2013 MANAGER 2 30-10-2013 GUEST 5 30-10-2013 REGISTERED 10 30-10-2013 MANAGER 3 LIKE THIS . var subquery = from eat in _customerRepo.Table group eat by new { yy = eat.CreatedOnUTC.Value.Year, mm = eat.CreatedOnUTC.Value.Month, dd = eat.CreatedOnUTC.Value.Day } into g select new { Id = g.Min(x => x.Id) }; var query = from c in _customerRepo.Table join cin in subquery.Distinct() on c.Id equals cin.Id select c; By above query I get minimum cutomers registerd on that day Thanks in advance

  • 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?

  • How do I fix a broken connection to DB2 from a web application?

    - by Eddie White
    I support some old web applications, VBScript-based ASP for the UI and VB6 COM modules for the business and data access layers. Last weekend, I installed DB2 Connect Enterprise Edition v8 fixpack 14 on several Windows 2000 servers, and one of the web apps errors out on null data when it calls the built in VBScript function FormatNumber. This numeric data is retrieved by a SQL Server query, but the only way the SQL Server column is populated is with the calculated results returned from a DB2 query earlier in a progression through several pages. When I installed DB2 Connect EE, one of the components loaded was MDAC 2.7. I followed corporate instructions and had the installation save an ODBC System Data Source, which reported a good connection when I tested it after the install. For what it's worth, the project references in the production VB6 modules pointed to MDAC 2.5. I have tried recompiling and deploying to COM on my test server new versions of the VB6 modules referencing MDAC 2.7. My development environment is Windows XP Pro, with MDAC 2.8 and DB2 Connect EE v9.5 installed. When I deployed the updated VB6 dlls, the CreateObject fails to instantiate the classes with the error message that "The class does not support automation or the requested interface". I've rolled the DB2 Connect install back and have reinstall v8 of the DB2 runtime client, which was the previous environment. The problem, however, persists.

  • How can I protect this code from SQL Injection? A bit confused.

    - by Craig Whitley
    I've read various sources but I'm unsure how to implement them into my code. I was wondering if somebody could give me a quick hand with it? Once I've been shown how to do it once in my code I'll be able to pick it up I think! This is from an AJAX autocomplete I found on the net, although I saw something to do with it being vulnerable to SQL Injection due to the '%$queryString%' or something? Any help really appreciated! if ( isset( $_POST['queryString'] ) ) { $queryString = $_POST['queryString']; if ( strlen( $queryString ) > 0 ) { $query = "SELECT game_title, game_id FROM games WHERE game_title LIKE '%$queryString%' || alt LIKE '%$queryString%' LIMIT 10"; $result = mysql_query( $query, $db ) or die( "There is an error in database please contact [email protected]" ); while ( $row = mysql_fetch_array( $result ) ) { $game_id = $row['game_id']; echo '<li onClick="fill(\'' . $row['game_title'] . '\',' . $game_id . ');">' . $row['game_title'] . '</li>'; } } }

  • 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.

  • sqlalchemy relation through another (declarative)

    - by clayg
    Is anyone familiar with ActiveRecord's "has_many :through" relations for models? I'm not really a Rails guy, but that's basically what I'm trying to do. As a contrived example consider Projects, Programmers, and Assignments: from sqlalchemy import create_engine from sqlalchemy.orm import sessionmaker from sqlalchemy import Column, ForeignKey from sqlalchemy.types import Integer, String, Text from sqlalchemy.orm import relation from sqlalchemy.ext.declarative import declarative_base Base = declarative_base() class Assignment(Base): __tablename__ = 'assignment' id = Column(Integer, primary_key=True) description = Column(Text) programmer_id = Column(Integer, ForeignKey('programmer.id')) project_id = Column(Integer, ForeignKey('project.id')) def __init__(self, description=description): self.description = description def __repr__(self): return '<Assignment("%s")>' % self.description class Programmer(Base): __tablename__ = 'programmer' id = Column(Integer, primary_key=True) name = Column(String(64)) assignments = relation("Assignment", backref='programmer') def __init__(self, name=name): self.name = name def __repr__(self): return '<Programmer("%s")>' % self.name class Project(Base): __tablename__ = 'project' id = Column(Integer, primary_key=True) name = Column(String(64)) description = Column(Text) assignments = relation("Assignment", backref='project') def __init__(self, name=name, description=description): self.name = name self.description = description def __repr__(self): return '<Project("%s", "%s...")>' % (self.name, self.description[:10]) engine = create_engine('sqlite://') Base.metadata.create_all(engine) Session = sessionmaker(bind=engine) session = Session() Projects have many Assignments. Programmers have many Assignments. (understatement?) But in my office at least, Programmers also have many Projects - I'd like this relationship to be inferred through the Assignments assigned to the Programmer. I'd like the Programmer model to have a attribute "projects" which will return a list of Projects associated to the Programmer through the Assignment model. me = session.query(Programmer).filter_by(name='clay').one() projects = session.query(Project).\ join(Project.assignments).\ join(Assignment.programmer).\ filter(Programmer.id==me.id).all() How can I describe this relationship clearly and simply using the sqlalchemy declarative syntax? Thanks!

  • 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.

  • Subsonic, child records, and collections

    - by Dane
    Hi, I've been working with subsonic for a few weeks now, and it is working really well. However, I've just run into an issue with child objects with additional partial properties. Some of it is probably me just not understanding the .Net object lifecycle. I have an object - search. This has a few properties like permissions and stuff, and it links to a child table called search_options. In my Asp.Net app, it loops through these search options and creates controls. Then on postback, it grabs the values and assigns it back to a "value" property on the search_option. This value property is a simple string that's defined in a partial class. I then want to create a method on the search object, called PerformSearch. This then loops through the child search_options, and performs a custom query based on the "value" property. However, even though I assign the "value" property to the child search_option, when I access it later via the search.search_options collection, it is null. I'm guessing that maybe because it's accessing it in two different places, it performs another lazy load from the DB and the value is lost? Is there a way to tell the class that it's already loaded or something? or a way to access it so it's not reloaded from the DB? Code is below (shitty pseudocode, not full version) : ASP.Net page, loading back the values from postback : dim obj_search as search = new subsonic.query.select().......' retrieves the search object for each opt as search_option in obj_search.search_options opt.Value = Ctype(FindControl("search_option_" + opt.search_option_id),Textbox).Text debug.print(opt.Value) ' value is correct next for each opt as search_option in obj_search.search_options debug.print(opt.Value) 'this is nothing next Now, the partial class : public partial class search_option private m_value as string public property Value() as string get return m_value end get set( byval value as string) m_value = value end set end property end class

  • Mysql Server Optimization

    - by Ish Kumar
    Hi Geeks, We are having serious MySQL(InnoDB) performance issues at a moment when we do: (10-20) insertions on TABLE1 (10-20) updates on TABLE2 Note: Both above operations happens within fraction of a second. And this occurs every few (10-15) minutes. And all online users (approx 400-600) doing read operation on join of TABLE1 & TABLE2 every 1 second. Here is our mysql configuration info: http://docs.google.com/View?id=dfrswh7c_117fmgcmb44 Issues: Lot queries wait and expire later (saw it from phpmyadmin / processes). My poor MySQL server crashes sometimes Questions Q1: Any suggestions to optimize at MySQL level? Q2: I thinking to use persistent connections at application level, is it right? Info Added Later: Database Engine: InnoDB TABLE1 : 400,000 rows (inserting 8,000 daily) & TABLE2: 8,000 rows 1 second query: SELECT b.id, b.user_id, b.description, b.debit, b.created, b.price, u.username, u.email, u.mobile FROM TABLE1 b, TABLE2 u WHERE b.credit = 0 AND b.user_id = u.id AND b.auction_id = "12345" ORDER BY b.id DESC LIMIT 10; // there are few more but they are not so critical. Indexing is good, we are using them wisely. In above query all id's are indexed And TABLE1 has frequent insertions and TABLE2 has frequent updates.

  • Get tag name and value of a given node using XMLReader, DOM, Xpath

    - by rossjha
    I need to query an xml document and then display specific tag values, e.g. forename, surname, group(dept), job_title. I'm using XMLReader as i may need to work with large XML files. I using DomXPath to filter the data, but i don't know how to retrieve the nodeName and value for each element. The code below only returns 'member' as the node name? Any help would be appreciated. <?php $reader = new XMLReader(); $reader->open('include/staff.xml'); while ($reader->read()){ switch($reader->nodeType){ case(XMLREADER::ELEMENT): if($reader->localName === 'staff'){ $node = $reader->expand(); $dom = new DomDocument(); $dom->formatOutput = true; $n = $dom->importNode($node, true); $dom->appendChild($n); $xp = new DomXpath($dom); $res = $xp->query("/staff/member[groups='HR']"); } } } echo $res->item(0)->nodeName; echo $res->item(0)->nodeValue; ?>

  • ASP.NET MVC Paging for a search form

    - by James Alexander
    I've read several different posts on paging w/ in MVC but none describe a scenario where I have something like a search form and then want to display the results of the search criteria (with paging) beneath the form once the user clicks submit. My problem is that, the paging solution I'm using will create <a href="..."> links that will pass the desired page like so: http://mysite.com/search/2/ and while that's all fine and dandy, I don't have the results of the query being sent to the db in memory or anything so I need to query the DB again. If the results are handled by the POST controller action for /Search and the first page of the data is rendered as such, how do I get the same results (based on the form criteria specified by the user) when the user clicks to move to page 2? Some javascript voodoo? Leverage Session State? Make my GET controller action have the same variables expected by the search criteria (but optional), when the GET action is called, instantiate a FormCollection instance, populate it and pass it to the POST action method (there-by satisfying DRY)? Can someone point me in the right direction for this scenario or provide examples that have been implemented in the past? Thanks!

    Hello, How to set a composite primary key for a "All in One" approach (grid defined in JS file, and data using jqGridEdit Class in php file) ? Please, for me a composite primary key of a table T, is a elementary primary key that is defined with some fields belong to this table T ! Here is my test, but i get no data and cannot use the CRUD operations : In my JS file i have this lines code: ... colModel":[ {"name":"index","index":"index","label":"index"}, // <= THAT'S JUST THE INDEX OF MY TABLE {"name":"user","index":"user","label":"user","key":true}, // <= A PART OF MY COMPOSITE PRIMARY KEY {"name":"pwd","index":"pwd","label":"pwd","key":true}, // <= A PART OF MY COMPOSITE PRIMARY KEY {"name":"state","index":"state","label":"state","key":true}, // <= A PART OF MY COMPOSITE PRIMARY KEY ... <= AND SO ON "url":"mygrid_crud.php", "datatype":"json", "jsonReader":{repeatitems:false}, "editurl": "mygrid_crud.php", "prmNames":{"id":"index"} // <= WHAT I NEED TO WRITE HERE ??? ... In my php file (mygrid_crud.php) : ... $grid = new jqGridEdit($conn); $query = "SELECT * FROM mytable WHERE user='$user' and pwd='$pwd' and state='$state'..."; // <= SELECT * it's ok or i need to specify all fields i need ? $grid->SelectCommand = $query; $grid->dataType = "json"; $grid->table = 'mytable'; $grid->setPrimaryKeyId('index'); // <= WHAT I NEED TO WRITE HERE ??? ... $grid->editGrid(); Please, say me what is wrong, and how to do to set a composite primary key in this approach !? Thank you so much for tour responses.

  • Multiple threads modifying a collection in Java??

    - by posdef
    Hi, The project I am working on requires a whole bunch of queries towards a database. In principle there are two types of queries I am using: read from excel file, check for a couple of parameters and do a query for hits in the database. These hits are then registered as a series of custom classes. Any hit may (and most likely will) occur more than once so this part of the code checks and updates the occurrence in a custom list implementation that extends ArrayList. for each hit found, do a detail query and parse the output, so that the classes created in (I) get detailed info. I figured I would use multiple threads to optimize time-wise. However I can't really come up with a good way to solve the problem that occurs with the collection these items are stored in. To elaborate a little bit; throughout the execution objects are supposed to be modified by both (I) and (II). I deliberately didn't c/p any code, as it would be big chunks of code to make any sense.. I hope it make some sense with the description above. Thanks,

  • Retrieve specific preceding sibling nodes attributes

    - by Matthieu BROUILLARD
    Is there an XPath way of recovering directly one specific attribute of preceding sibling nodes of an XML node using an XPath query? In the following example, I would like to retrieve the values of the alt attribute of each img nodes that precede the div element marked with the id=marker. <content> <img alt="1" src="file.gif" /> <img alt="2" src="file.gif" /> <img alt="3" src="file.gif" /> <img alt="4" src="file.gif" /> <div id='marker'></div> </content> For this example, I want to retrieve the values 1 2 3 4. I use the following XPath query //div[@id='marker']/preceding-sibling::img in order to retrieve the node list I want <img alt="1" src="file.gif"/> <img alt="2" src="file.gif"/> <img alt="3" src="file.gif"/> <img alt="4" src="file.gif"/> As it is a node list I can then iterate on the nodes to retrieve the attribute value I am looking for, but is there an XPath way of doing it? I would have expected to be able to write something like: //div[@id='marker']/preceding-sibling::img@alt or //div[@id='marker']/preceding-sibling@alt::img but I don't even know if it is possible once you have used an XPath Axe like preceding-sibling.

  • Deselect dates in ASP.NET Calendar Control

    - by yomismo
    I'm trying to select and de-select dates on a C# Web Calendar control. The problem I have is that I can select or deselect dates except when there is only a single date selected. Clicking on it does not trigger the selection changed event, so Ineed to do something on the dayrender event but I'm not sure what or how. Edit: Added the Pre_Render event code. This seems to work now, however it seems a little bit erratic,e.g. select date A : OK Select date B :OK deselect them both: OK select date A: Does not work, need to select it twice deselect date A : Ok Select Date C: dates A and c are selected @John Yes, I am aware that the control is part of the .NET 2.0 framework and nothing to do with C# per se. Code so far: public static List<DateTime> list = new List<DateTime>(); protected void Calendar1_DayRender(object sender, DayRenderEventArgs e) { if (e.Day.IsSelected == true) { list.Add(e.Day.Date); } Session["SelectedDates"] = list; } protected void Calendar1_SelectionChanged(object sender, EventArgs e) { DateTime selection = Calendar1.SelectedDate; if (Session["SelectedDates"] != null) { List<DateTime> newList = (List<DateTime>)Session["SelectedDates"]; foreach (DateTime dt in newList) { Calendar1.SelectedDates.Add(dt); } if (searchdate(selection, newList)) { Calendar1.SelectedDates.Remove(selection); } list.Clear(); } } public bool searchdate(DateTime date, List<DateTime> dates) { var query = from o in dates where o.Date == date select o; if (query.ToList().Count == 0) { return false; } else { return true; } } protected void Calendar1_PreRender(object sender, EventArgs e) { if (Calendar1.SelectedDates.Count == 1) { foreach (DateTime dt in list) { if (searchdate(dt, list) && list.Count == 1) { Calendar1.SelectedDates.Clear(); break; } } } }

  • Drupal Views api, add simple argument handler

    - by LanguaFlash
    Background: I have a complex search form that stores the query and it's hash in a cache. Once the cache is set, I redirect to something like /searchresults/e6c86fadc7e4b7a2d068932efc9cc358 where that big long string on the end is the md5 hash of my query. I need to make a new argument for views to know what the hash is good for. The reason for all this hastle is because my original search form is way to complex and has way to many arguments to consider putting them all into the path and expecting to do the filtering with the normal views arguments. Now for my question. I have been reading views 2 documentation but not figuring out how to accomplish this custom argument. It doesn't seem to me like this should be as hard as it seems to me like it must be. Leaving aside any knowledge of the veiws api, it would seem that all I need is a callback function that will take the argument from the path as it's only argument and return a list of node id's to filter to. Can anyone point me to a solution or give me some example code? Thanks for your help! You guys are great. PS. I am pretty sure that my design is the best I can come up with, lets don't get off my question and into cross checking my design logic if we can help it.

  • Best way to store and deliver files on a CMS

    - by Tio
    Hi all.. First of all, this isn't another question about storing images on DB vs file system. I'm already storing the images on the file system. I'm just struggling to find a better way to show them to all my users. I' currently using this system. I generate a random filename using md5(uniqueid()), the problem that I'm facing, is that the image is then presented with a link like this: <img src="/_Media/0027a0af636c57b75472b224d432c09c.jpg" /> As you can see this isn't the prettiest way to show a image ( or a file ), and the name doesn't say anything about the image. I've been working with a CMS system at work, that stores all uploaded files on a single table, to access that image it uses something like this: <img src="../getattachment/94173104-e03c-499b-b41c-b25ae05a8ee1/Menu-1/Escritorios.aspx?width=175&height=175" /> As you can see the path to the image, now has a meaning compared to the other one, the problem is that this put's a big strain in the DB, for example, in the last site I made, I have an area that has around 60 images, to show the 60 images, I would have to do at least 60 individual query's to the database, besides the other query's to retrieve the various content on the page. I think you understand my dilemma, has anyone gone trough this problem, that can give me some pointers on how to solve this? Thanks..

  • How should child views of UIScrollView report their bounds for contentSize?

    - by Mike
    I'm looking more for advice on the correct design for a view. What I have is a UIScrollView that contains one or more custom Views I have created. My problem is, who reports to the scrollview what it's contentSize should be? I have the following: UIView +-UIScrollView +-CustomView 1 with dynamic height depending on data +-CustomView 2 with dynamic Height depending on data The UIViewController creates new instances of the custom views with data and then adds them as subviews to the UIScrollView. The problem I'm having is how to set the value of the scrollview's contentSize? Right now, I'm not doing that and the contents of the scrollview are clipped with no scrolling possible. Should the custom view call [parent setContentSize:] in its drawRect:? Should the UIViewController query the custom view after creation to get its bounds and then call setContentSize? Should I subclass the UIScrollView to override addSubView to query each subview's height? Is there something else I'm missing? I hope I explained that properly. I'm new to this and still getting a handle on things.

  • Reporting Services keeps erasing my dataset parameters

    - by Dustin Brooks
    I'm using a web service and every time I change something on the dataset, it erases all my parameters. The weird thing is, I can execute the web service call from the data tab and it prompts for all my parameters, but if I click to edit the data the list is empty or if I try to preview the report it blows up because parameters are missing. Just wondering if anyone else has experienced this and if there is a way to prevent this behavior. Here is a copy of the dataset, not that I think it matters. This has to be the most annoying bug (if its a bug) ever. I can't even execute the dataset from the designer without it erasing my parameter list. When you have about 10 parameters and you are making all kinds of changes to a new report, it becomes very tedious to be constantly re-typing the same list over and over. If anything, studio should at least be able to pre-populate with the parameters the service is asking for. sigh Wheres my stress ball... <Query> <Method Namespace="http://www.abc.com/" Name="TWRPerformanceSummary"/> <SoapAction>http://www.abc.com/TWRPerformanceSummary</SoapAction> <ElementPath IgnoreNamespaces="true"> TWRPerformanceSummaryResponse/TWRPerformanceSummaryResult/diffgram/NewDataSet/table{StockPerc,RiskBudget,Custodian,ProductName,StartValue(decimal),EndValue(decimal),CostBasis(decimal)} </ElementPath> </Query>

  • PDO Database Connections Problem

    - by Metropolis
    Hey Everyone, Over a year ago I created my own database classes which use PDO, and handle all preparing, executing, and closing connections. These classes have been working great up until now. There are two different database severs I am grabbing from, MySQL, and MS SQL Express. I am retrieving an employee id from the MySQL server and using it to get that employees information from the MS SQL server. There are about 11k records coming from the MySQL server and my program is only making it through 1200 before crashing with an error like the following. Connection failed (odbc:Driver=FreeTDS;Servername=MSSQLExpress;Database=SMDINC) Class (PDOException) SQLSTATE[08001] SQLDriverConnect: 0 [unixODBC][FreeTDS][SQL Server]Unable to connect to data source It seems like the program is not able to connect to the data source, but it is running the exact same query about 30 times before this and having no problem. Also, I have thoroughly checked all of the data coming into the query and it all looks fine. I believe the issue may be that there are to many connections being created, but I have tried to close all connections in many different places, and nothing seems to be fixing the problem. Any debugging help, or suggestions would be appreciated! Craig Metrolis

  • How to deal with "partial" dates (2010-00-00) from MySQL in Django?

    - by Etienne
    In one of my Django projects that use MySQL as the database, I need to have a date fields that accept also "partial" dates like only year (YYYY) and year and month (YYYY-MM) plus normal date (YYYY-MM-DD). The date field in MySQL can deal with that by accepting 00 for the month and the day. So 2010-00-00 is valid in MySQL and it represent 2010. Same thing for 2010-05-00 that represent May 2010. So I started to create a PartialDateField to support this feature. But I hit a wall because, by default, and Django use the default, MySQLdb, the python driver to MySQL, return a datetime.date object for a date field AND datetime.date() support only real date. So it's possible to modify the converter for the date field used by MySQLdb and return only a string in this format 'YYYY-MM-DD'. Unfortunately the converter use by MySQLdb is set at the connection level so it's use for all MySQL date fields. But Django DateField rely on the fact that the database return a datetime.date object, so if I change the converter to return a string, Django is not happy at all. Someone have an idea or advice to solve this problem? How to create a PartialDateField in Django ? EDIT Also I should add that I already thought of 2 solutions, create 3 integer fields for year, month and day (as mention by Alison R.) or use a varchar field to keep date as string in this format YYYY-MM-DD. But in both solutions, if I'm not wrong, I will loose the special properties of a date field like doing query of this kind on them: Get all entries after this date. I can probably re-implement this functionality on the client side but that will not be a valid solution in my case because the database can be query from other systems (mysql client, MS Access, etc.)
