从Firebird 2.0存储过程填充ASP.NET SqlDataSource

Question

I am working on a project where I do not have any control over the versions of products that I have been asked to work with.

I am building an ASP.NET user control. Data is retrieved via SqlDataSource controls working against Firebired 2.0 databases. Everything was fine until I needed to populate one of the SqlDataSource controls via a stored procedure rather than a SELECT statement.

I have verified that the procedure is returning data in EMS SQL Manager for Interbase and Firebird. However, when I set the SqlDataSource 's SelectCommand property to EXECUTE PROCEDURE myProc and call Select() , I am getting no data.

My procedure takes no input parameters so it seems to me that it should be straight-forward.

The reality of the situation is that I could use a simple SELECT statement if I were able to move to even 2.1 as I would have access to the List() aggregate function, but that is not a possibility.

Does anyone have any experience trying to do this? Does the procedure call need to be modified in any way? Any help would be greatly appreciated.

Answer 1

I would normally do this like so (against SQL Server) :

// set the SqlDataSource's SelectCommand to the *name* of the stored procedure
myDataSource.SelectCommand = "myProc";

// tell the SqlDataSource that this is a *stored procedure* now
myDataSource.SelectCommandType = CommandType.StoredProcedure;

Since your stored procedure takes no input parameters at all, this should really be all!

With SQL Server, selecting the data works just fine with this setup.

Answer 2

If it is selectable stored procedure (it has SUSPEND command in it) then you should call it with SELECT statement, not with EXECUTE PROCEDURE statement. So set your SelectCommand to

SELECT * FROM spName

and it should work.
