The problem should be the internal call function. I continue to debug. A single pure method is possible and successful.
I know the reason. My MD5 has numbers in the first letter OK OK OK
I'm currently experiencing 2 issues with the SQL module:
when inserting a new record, i have to insert as ID a zero padded number (ex: 0000001740 ) but the "Data field" has a built in feature that auto converts strings to numbers.
so it trasform the value from 0000001740 to 1740

when using "update single record" or "update multiple records" nothing happens (while "delete single record", "insert records" and "select single record" works )

anyone has any idea/suggestions?
