DECLARE @TBL TABLE (NAME VARCHAR(100))

INSERT INTO @TBL VALUES('A.XYZ'),('B.PQR'),('C.JPG'),('A.ABC')

I want to find only *.XYZ,*.PQR,*.JPG and nothing else. Can we write a single regular expression to return this?

Thanks

khtan: What if the length of the extension is 4, say .jpeg?

Visakh:

DECLARE @TBL TABLE (NAME VARCHAR(100))

INSERT INTO @TBL VALUES('A.xyz'),('B.pqr'),('C.jpg'),('A.ABC'),('A.jpeg')

SELECT * FROM @TBL WHERE NAME LIKE '%[.XYZ|.PQR|.JPEG]'

It returns .jpg too but it should not. I thought this was a generic solution, anyway we can include just any extension.

Thanks

DECLARE @TBL TABLE (NAME VARCHAR(100))

INSERT INTO @TBL VALUES('A.xyz'),('B.pqr'),('C.jpg'),('A.ABC'),('A.jpeg'),('A.wxyz')

SELECT t.* FROM @TBL t
CROSS APPLY (VALUES ('.XYZ'),('.PQR'),('.JPEG'))t1(pat)
WHERE NAME LIKE '%' + pat


output
-----------
NAME
-----------
A.xyz
B.pqr
A.jpeg
