Problem with Executing Mysql stored procedure
The stored procedure builds without any problem. The purpose of this is to take backup of selected tables to a script file. when the SP returns a value {Insert statements}.
I am using the below MySql stored procedure, created by SQLWAYS [Tool to convert MsSql to MySql]. The actual MsSql SP is from http://www.codeproject.com/KB/database/InsertGeneratorPack.aspx
When i execute the SP in MySql Query Browser, It says "Unknown column 'tbl_users' in 'field list'"
What would be the problem ? Because there was no error when i build-ed this Converted MySql SP.
Help..
