Question

I would like to be able to match a single field based upon multiple patterns contained in another table, kind of like and IN clause for LIKE comparisons. The following query obviously doesn’t work, but it expresses what I am trying to accomplish.

SELECT * 
FROM TableA 
WHERE TableA.RegCode Like (
    SELECT '%' + TableB.PartialRegCode + '%'
    FROM TableB)

I’d rather not resort to cursors if there is a better way.

Answer 1

SELECT * 
FROM TableA a
INNER JOIN TableB b on a.RegCode like '%' + b.PartialRegCode + '%'
