I can't imagine using this feature in the context of a regular PL/SQL programming environment, but it will be extremely valuable in any migration projects. RETURN_RESULT Rather than defining explicit ref cursor out parameters, theRETURN_RESULTprocedure in theDBMS_SQLpackage allows you to pass th...
With your formula, for example, the part where you are concatenating rows 1:1&2:2, this is what implicit intersection returns (screenshot) - it will only return the result corresponding to the same column as the formula (since I entered the formula in column B, it conca...
