Ive created a new LINQ To SQL class and dragged several tables across from my server, in my code I access them like this
[Code]....this is all ok, however, I have several stored procedures that I want to use as well, but when I drag the stored procedures across I get a compilatiopn error
Error 60 'DB_BL.DB_BLDataContext': type used in a using statement must be implicitly convertible to 'System.IDisposable'
how do I use stored procedures from LINQ with a using clause ?
If this is not the appropriate forum for this I didn't see any linq specific forum listed.
I am about to start a new project and I would like to use it as an opportunity to update myself with the newer technologies, like ajax and linq.
All my database CRUD operations will be done by sql stored procedures, does linq still make sense when doing that? I watched a couple introductory videos on linq and none of them dealt with stored procedures, thats why I'm wondering.
I have been chasing this erorr all day and coming up blank. I created a stored proceudre(fairly complicated logic), added it to the context, and set the return type to a specific entity type.
It generated this:
[Function(Name="dbo.usp_ServiceTemplateSelectByFkID")] public ISingleResult<ServiceTemplate> usp_ServiceTemplateSelectByFkID([Parameter(Name="FkId", DbType="Int")] System.Nullable<int> FkId) { IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), FkId); return ((ISingleResult<ServiceTemplate>)(result.ReturnValue)); }
I call it from my service with the following method:
public ISingleResult<ServiceTemplate> GetByFkId(int FkId) { return Db.usp_ServiceTemplateSelectByFkId(FkId); }
I have tested the stored procedure and it returns the results I want. When I make the service call from the controller, it doesn't error out, however, it should return 4 records in this instance and instead, it returns the same 4 records (repeating the first record 4 times).
In addition, in my controller code, I am using the MVCContrib ToPagedList() method which doesn't appear to work with the ISingleResult interface (forward only cursor, I'm guessing). I have attempted converting the service results to IQuery, List, and Array, however, I still have the problem with the first record being repeated 4 times.
The database I am using has a schema called EQB and as such, my stored procedures are named as EQB.usp_SelectFunds, EQB.usp_SelectAccount, etc.
On the select tab of the Configure Data Source screen, I choose to use a stored procedure. The dropdown shows my stored procedures, however, the schema name does not show up in front of the stored procedures in the drop down. I see only usp_SelectFunds, usp_SelectAccount, etc.
I select one of the stored procedures and when I click TEST, I get the message that the stored procedure is not found. If I instead choose to use a SQL statement instead on the configuration screen and enter EXEC EQB.usp_SelectFunds and click TEST, it works fine.
Why are my stored procedures not showing up correctly in the stored procedure drop down and how can I fix this?
when person A connects to sql server from their machine and executes a stored procedure (a stored procedure which runs a query and sends an email) - it executes and the email is received.
when person B connects to sql server from their machine and executes the same stored procedure, it executes but the email is never received.
does this mean the stored procedure is executing locally on both users machines?
if not....then why does person B's execution of the stored procedure not generate the email?
Should I just write to file before a stored procedure is executed or should I log the stored procedure into a table? If the latter one is recommended, how should I go about doing that?
I am having a problem returning a value from a stored procedure when using SqlDataSource. The stored procedure is executing because 'invoice_no is incrementing but Myreader.HasRows is always false.
CREATE PROCEDURE `GetInvoiceNumber`(IN username VARCHAR(50), OUT InvoiceNum INT) BEGIN INSERT INTO invoice (employee) VALUES (username); SELECT MAX(invoice_no) INTO InvoiceNum FROM invoice; END
I'm totally new to MVC (started this morning), and am totally at a loss where to start. I need to rebuild an existing website. I already have a SQL Server 2005 database with tables and stored procedures. In the old version of the website, I built a function to call stored procedures and return the results as a datareader in VB.Net.
I want to use ASP.NET MVC with C#.
The first question I have is: Where would I put the code for the function that calls stored procedures ?
My second question is: Where do I go from there? I just need to get a sense of the basic way to handle presenting a dynamic website. I just want to start out with a Site.Master and display my menus which need to be generated dynamically from my database. I've been googling all day and I haven't really found any posts which answer all of my questions.
I'm using Linq to Sql to call some stored procedures for more complex work; is there any way Linq to Sql can tell me when the output columns from the stored procedure do not match the properties of my entity object? It seems that Linq to Sql tries its best to match the columns and ignores any mismatches.
Is it possible to change the select, insert and update stored procedure of an SqlDataSource at run time. I don't mean to change the definition of the stored procedure, but I mean to change the assignment, i.e. To change the select stored procedure from "selectSP1" to "selectSP2" at run time. Is it possible?
I open a sqlconnection and sqlcommand. I execute a stored procedure and get the scope_identity from that procedure to be used within another procedure that needs to be fired. Unfortuntley if the second procedure fails forwhatever reason the data change for the first procedure commits anyway. I kind of want to do a began transaction end transaction on the c#.net side. Also I need to execute a stored procedure multiple times....
I am passing values from textboxes on the webform to my stored procedures where it should insert values passed.
It is giving an error like Cannot implicitly convert type 'string' to 'System.Data.SqlClient.SqlParameter' at place where I am cmdselect.Parameters.Add("@PackageName", SqlDbType.VarChar, 50) = PN; where PN is string type .
I've recently inherited an ASP.NET 2.0 project from other developers and they have a LinqToSql datacontext with stored procedures. I've been asked to modify one of the SPs which is essentially just adding a couple columns to the database table and then those to parameters to the SP. So I delete the existing SP from the L2S context and drag in the new one with the additional fields, and all hell breaks loose. Suddenly I get over 20 errors! What seems to have occured is L2S has modified many other stored procedures that I haven't even touched and changed the return type from ISingleDefault<some object> to int. I've never used stored procedures before with L2S so I don't know if this is standard behavior or not. Does anyone know why this has happened and how to fix it to set the correct return type?
Recently I dragged a stored procedure onto the methods pane. I was thinking this stored procedure was now part of the datacontext and would get regenerated when creating the database.
I have access to two servers, one with my development database on, and another with the live database on.
All SQL Stored Procedures, Functions, Views are encrypted on the live database (using WITH ENCRYPTION in my query)
However I'm concerned I might accidentally encrypt a bunch of SProcs on my development database meaning I can no longer view/edit that code.
I have full control over the server and database, and was wondering if there is a way I can prevent these from being encrypted, therefore throwing up an error when this is attempted?
I was reviewing my old post about this issue with a accessdatasource and that was simple since the Select, Update and Delete were all written within the datasource.
But this page im having issues with is using SQLDataSource and pointing to Store procedures. My issue is that i have created the sqldatasource with Insert(storeprocedure), Select(actual select statement), Update(storeprocedure) and was trying to take advantage of gridviews capabilities for editing when connected to a datasource that has all those elements setup.
Here is my datasource and gridview code: The gridview row goes into edit mode, but the changes never take affect on the database.
