My other question is how do we handle differences between jdbc data sources? E.g. select concat('10', NULL) returns NULL in MySQL, whereas 10 in Exasol. Does developing a translator mean we need to eliminate such differences to have same results or just make sure that queries coming out of TEIID are valid for that particular data source? was (Author: rkorytkowski): Thanks [~rareddy]!
