What is the problem, exactly? Are you getting any error messages?

RE: Problem on DB2 Update SQL in VB.Net

Actually there is no error on my sample code, it only replaces the Alpha_Code of ITEMTEST table with a blank.. I need to replace the Alpha_code field in ITEMTEST table with the right Alphacode in CSVTEST Table.

My exact problem, what is the complete set of SQL Update command to replace the Alpha_code of ITEMTEST table?
