I need to execute a SQL Server system stored procedure, programmatically, and since it executes in the current schema, I need to change it on the fly.
Like this
Statement st = connection.createStatement(); st.execute("EXEC SP_ADDUSER ' ', ' '");
But SP_ADDUSER only executes on the current schema set for the connection, so if I wanted to create users in various schemas, I'd need to change it, and that's what I am looking for.
I don't believe it's possible to change which database a connection points to.
You'll probably need to create a separate DataSource/Connection for each database (schema).
EXEC <DatabaseName>..sp_adduser
can be run from a connection to any database (even master
, say). The connection will not be affected.
For instance, the following appears to work fine on my system:
USE master
EXEC sp_addlogin 'test1'
EXEC SandBox..sp_adduser 'test1'
The same things works fine through the client. Is your client connection altering your SQL?
using System;
using System.Data.SqlClient;
namespace TestUse
{
class Program
{
static void Main(string[] args)
{
SqlConnection cn = new SqlConnection("Server=(local);Database=master;Trusted_Connection=True;");
cn.Open();
SqlCommand cmd = new SqlCommand("USE master; EXEC sp_addlogin 'test1'; EXEC SandBox..sp_adduser 'test1'", cn);
cmd.ExecuteNonQuery();
cn.Close();
}
}
}
