Problem converting MsSql to MySql Stored procedure
- by karthik
Original source of MsSql SP is here..
http://www.codeproject.com/KB/database/InsertGeneratorPack.aspx
I am using the below MySql stored procedure, created by SQLWAYS [Tool to convert MsSql to MySql].
The purpose of this is to take backup of selected tables to a script file. when the SP returns a value {Insert statements}.
When i Execute the Below SP, i am getting a weird Result Set :
SQLWAYS_EVAL# ll(cast(UidSQLWAYS_EVAL# 0)),'0')+''','+SQLWAYS_EVAL# ll(UserNameSQLWAYS_EVAL# '+SQLWAYS_EVAL# ll(PasswordSQLWAYS_EVAL# '+
I see a lot of "SQLWAYS_EVAL#" in the code, which is produced in the result too.
What values need to be passed instead of "SQLWAYS_EVAL#".
So that i get the proper Insert statements for each record in the table.
I am new to MySql. Please help me. Its Urgent. Thanks.
