The ordering of the data I have this code: DECLARE @Test TABLE (testString VARCHAR(1) COLLATE SQL_Latin1_General_CP1_CS_AS); INSERT INTO @Test (testString) VALUES ('a') , ('b') , ('c') , ('A') , ('B') , ('C'); Then I run this in the same batch. SELECT testString FROM @Test WHERE testString LIKE '[a-B]'; What is returned (each letter in the answer would be on a separate row)? Answer: a, B Explanation: This is an interesting collation issue. The ordering of the entire set, given the collation, is: A a B b C c In this case, the return is a, B. |
