INF: ODBC Stored Procedures odbc#userid######## on SQL Server

• Microsoft Open Database Connectivity, version 1.0

SUMMARY

When an ODBC enabled application uses prepared execution to execute an SQL query on SQL Server and the user has permission to create stored procedures, the ODBC SQL Server driver creates a stored procedure with a name like "odbc#userid########" (for example, odbc#sa2147024896) on SQL Server and executes that stored procedure.

The stored procedure is created in response to a SQLPrepare ODBC call and is executed when SQLExecute is called. Normally, when the connection is closed, the driver drops these stored procedures. Also, if the user does not have Create Proc permissions, the stored procedures are not created and SQL statements are executed directly.

However, under certain situations when a connection might be terminated without closing the connection, the driver is not able to delete the stored procedures. This can happen if the client process terminates abnormally and is a more common occurrence in a development environment.

This article describes how to remove these stored procedures from the SQL Server.

MORE INFORMATION

To remove these stored procedures, follow these steps. Make sure no ODBC client is connected to the server when the following steps are carried out.

1. Run the following script, with actual database name in the USE command, using ISQL.EXE or any other SQL Server client tool and save the output so generated in a file called DROP.SQL:

         USE  <database_name>
         go
         SELECT CHAR(13) + CHAR(10)+ "DROP PROCEDURE " + NAME +
                CHAR(13) + CHAR(10) + "go" +
                CHAR(13) + CHAR(10)
         FROM sysobjects
         WHERE name LIKE "ODBC%"
         go
   
   

2. Modify the DROP.SQL script so generated to include a USE <database_name> followed by a go at the top of the file. Remove any "-------" lines generated by the tool to separate the header and the results. Delete any "(X row(s) affected)" line if generated in the output by the tool.

   Then, the DROP.SQL script file should look something like:

         USE <database_name>
         go
   

         drop procedure odbc#sa1855970
         go
   

         drop procedure odbc#sa1232424
         go
   

         ...
   

3. Run the DROP.SQL as the input script using a SQL client tool. For example, using ISQL.EXE:

         isql -S<server> -Usa -P<password> -idrop.sql
   

   and verify that no errors were reported.

   NOTE: If permission to create stored procedures is revoked from the users, the SQL Server driver will not create these stored procedures. This can be used as a workaround if it is desired that no stored procedures be created by the driver.
