Oct 15, 2014 · =INDEX(B:B,MATCH(C2,A:A,0)) I should mention that MATCH checks the position at which the value can be found within A:A (given the 0, or FALSE, parameter, it looks only for an exact match and given its nature, only the first instance found) then INDEX returns the value at that position within B:B.

Apr 13, 2013 · For example, ab|de would match either side of the expression. However, for something like your case you might want to use the ? quantifier, which will match the previous expression exactly 0 or 1 times (1 times preferred; i.e. it's a "greedy" match).

DECLARE @Table TABLE( Val1 VARCHAR(MAX), Val2 VARCHAR(MAX) ) INSERT INTO @Table (Val1) SELECT '1' works. You need to be more specific with the columns specified

Jun 3, 2010 · OK, but of course then the match result will be an empty string (with a successful match). If you're just checking whether a match is possible, then this doesn't matter. So yes, omit the .*$, and you're done faster. –
