Customizing ACS Code Generator DLLs (SQL code)
If you want to customize how ACS generates SQL code, create a customized version of the provided ACS Code Generator DLL.
You create a customized version of the ACS Code Generator DLL by changing the TDK model from which the ACS Code Generator DLL was generated, and then generating a new ACS Code Generator DLL through TDK.
For more information about using TDK to customize a TDK model, see Overview of customizing ACS Code Generator DLLs - TDK code generation transformation patterns model (TDK) (link works only if TDK is installed).
