Is there a character, say, $,
SELECT * FROM Persons WHERE firstName='Peter' AND areaCode=$;
such that the statement would return the same as
SELECT * FROM Persons WHERE firstName='Peter'
i.e. areaCode=$ would always return always true and, thus, effectively “turns of” the criteria areaCode=...
I’m writing a VBA code in Excel that fetches some rows based on a number of criteria. The criteria can either be enabled or disabled. A character like $ would make the disabling so much easier.
