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?
View 4 RepliesI am using Visual Studio 2008 and SQL Server 2008 and have added a SQL datasource to my form.
When I configure the datasource, I choose my connection string which looks like this in my webconfig:
<connectionStrings>
<add
name="PSFSPRD_ConnectionString"
connectionString="Data
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?

Im new to ASP.NET (Normally use PHP), and im currently designing a website in VB.NET and SQL Server.

View 3 Replieswe have sql server running on a server.
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?
I want to write dynamic store procedure means 1 select_sp, 1 update_sp, 1 insert_sp, 1_delete_sp for all tables.
How it is used in secured manner.
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?
View 4 RepliesI 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.
Here is the table definition
`invoice_no` int(10) NOT NULL AUTO_INCREMENT,
`employee` varchar(50) DEFAULT NULL,
`create_date` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`invoice_no`)
Here is the stored procedure:
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
And here is my code.

Ive created a new LINQ To SQL class and dragged several tables across from my server, in my code I access them like this

View 2 RepliesIf 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 like to use my own stored procs as much as possible.
That way I know exactly what's happening and I can explain and control things.
I'm using stored procs with LINQ to SQL for CRUD operations.
For select, insert and delete - using stored procs with LINQ to SQL is pretty straightforward.
However, if I want to use my own custom stored procs with L2S for updates what's the best way to accomplish this?
Can you provide some code that shows the best approach that you would personally choose for this?

The only Stored procedure execute is the last one TSD_UpdateTimeCardEndofDay
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 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.
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.

I have a database linked to a calendar. I had a peice of code that retrieved dates from a database and populated the calendar. I wanted to tidy up my code using stored procedures (they seem neater & i assume there's a benefit somewhere). so i came up with this, however it's not working. The calendar displays, but it's not being populated with the database entries. The SqlCommand & SqlParameter I have working elsewhere in my code; as with the SqlDataAdapter (which also worked before i tried to conver to a storedprocedure!) but combining these three (SqlCommand, SqlParameter & SqlDataAdapter) seem to be causing me problems.It's probably something stupid but if someone could take a look and point me in the right direction,

I moved my website to the hosting control panel (ASP.NET files and SQL 2005 database).The hosting provider does not allow the SQL stored procedures with schema name 'dbo' (for example - the provider does not allow 'dbo.aspnet_CheckSchemaVersion'). So, all'dbo' schema became 'myusername' ie 'myusername.aspnet_CheckSchemaVersion' in theSQL database. Now, when I open my website, I am getting the following error -Could not find stored procedure 'dbo.aspnet_CheckSchemaVersion'.What change should I make in my ASP.NET (C#) to make the website to look for 'myusername.aspnet_CheckSchemaVersion', instead of 'dbo.aspnet_CheckSchemaVersion'?
