which is better - count({$<columnA={"*"}>columnB} or count({$<columnA={"<> Null()"}>}columnB)
Hi all,
Please help me understand the differences in execution and the way of execution of count({$<columnA={"*"}>columnB} and count({$<columnA={"<> Null()"}>}columnB) .
My requirement is to count the number of columnB records where the field columnA is not null.
