Collation Conflict

Question

i always got the message "Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Latin1_General_CI_AI" in the equal to operation." when i run the script that came from MSSQL 2005 server. btw i used MSSQL 2008.

here is the script

Answer 1

When you compare/aggregate columns with different collations you must coherence at least one of them to the collation you want, using the COLLATE expression. Eg, say you have a column c1 with collation Latin1_General_CI_AI in table Table1 and a column c2 with collation SQL_Latin1_General_CP1_CI_AS in table Table2 and you want to union the two:

SELECT c1 COLLATE SQL_Latin1_General_CP1_CI_AS
FROM Table1
UNION ALL
SELECT c2 
FROM Table2;
