Using Cursors

Using Cursors:

DECLARE @date_key INT

DECLARE date_cursor CURSOR FOR

SELECT date_key FROM dim_date WHERE [year] = 2013 ORDER BY date_key
 
OPEN date_cursor
FETCH NEXT FROM date_cursor INTO @date_key

WHILE @@FETCH_STATUS = 0
BEGIN

    SELECT @date_key

    --Insert code by @date_key here
   
   
    FETCH NEXT FROM date_cursor INTO @date_key
END

CLOSE date_cursor
DEALLOCATE date_cursor

Collation Conflict between databases (tempdb and user databases)

Msg 468, Level 16, State 9, Line 21
Cannot resolve the collation conflict between "Latin1_General_CI_AS" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation.

Use the COLLATE DATABASE_DEFAULT suffix on VARCHAR columns:

SELECT *
FROM hif_dim_account AS a
INNER JOIN #temp_hierarchy AS t
  ON t.account COLLATE DATABASE_DEFAULT = a.account COLLATE DATABASE_DEFAULT
INNER JOIN hif_dim_hierarchy AS h ON h.business_description COLLATE DATABASE_DEFAULT = t.business_description COLLATE DATABASE_DEFAULT
