Supported functions

When you enable SQL ELT optimization, the Secure Agent converts the expression in the transformation by determining equivalent functions in the database. If there is no equivalent function in the database, the Secure Agent processes the transformation logic.
The following table summarizes the availability of SQL ELT functions in Teradata:
