Hi,
I have 20+ years experience in variety of database platforms such as MSSQL, MySQL, Sybase ASE etc.
what is the underlying database used in your coldfusion environment?
please let us details such as database platform, version etc then I can check the feasibility and let you know.
if you could share what kind of issues you are facing for the 5 tables for which you are having issues and also process used for export of data it would be helpful to check the feasibility.
hope to hear from you
regards
Babu
