Procedure expects parameter which was not supplied.
- by Tony Peterson
I'm getting the error when accessing a Stored Procedure in SQL Server
Server Error in '/' Application.
Procedure or function 'ColumnSeek' expects parameter '@template', which was not supplied.
This is happening when I call a Stored Procedure with a parameter through .net's data connection to sql (System.data.SqlClient), even though I am supplying the parameter. Here is my code.
SqlConnection sqlConn = new SqlConnection(connPath);
sqlConn.Open();
// METADATA RETRIEVAL
string sqlCommString = "QCApp.dbo.ColumnSeek";
SqlCommand metaDataComm = new SqlCommand(sqlCommString, sqlConn);
metaDataComm.CommandType = CommandType.StoredProcedure;
SqlParameter sp = metaDataComm.Parameters.Add("@template", SqlDbType.VarChar, 50);
sp.Value = Template;
SqlDataReader metadr = metaDataComm.ExecuteReader();
And my Stored Procedure is:
USE [QCApp]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[ColumnSeek]
@template varchar(50)
AS
EXEC('SELECT Column_Name, Data_Type FROM [QCApp].[INFORMATION_SCHEMA].[COLUMNS]
WHERE TABLE_NAME = ' + @template);
I'm trying to figure out what I'm doing wrong here.
Edit: As it turns out, Template was null because I was getting its value from a parameter passed through the URL and I screwed up the url param passing (I was using @ for and instead of &)
