In order to do mapping, you will need to implement processRequestData that you have already done.
Under which circumstances do i need to implement this function processRequestSQL() ?
this function can be used to modify SQL statement which is a string and returns the modified SQL statement in a message body.
Check this official guide. Please dont mix two different queries in this thread, you can raise a new thread on this.
I have not deployed the Zipped file directly.
Give a try and share your findings.
Looping Carlos Roggan for more inputs.
