hi,
if i have the following records:

col1
abc
Abc
aBc
abC
ABC

doing a select with a where col1 = 'abC' will return me all the rows in the above table.
I would like it to return only the fourth row.
how to do this?

thanks in advance
rashid

You could change the collation of the column to Case Sensitive

Example:


CREATE TABLE #MyTemp(Col1 varchar(3)) --Using My Default Collation
GO
INSERT #MyTemp(Col1)
SELECT 'abc' UNION ALL
SELECT 'Abc' UNION ALL
SELECT 'aBc' UNION ALL
SELECT 'abC' UNION ALL
SELECT 'ABC'
GO

SELECT *
FROM #MyTemp
WHERE Col1 = 'abC' --All records will be returned
GO

ALTER TABLE #MyTemp ALTER COLUMN Col1
            varchar(3)COLLATE Latin1_General_CS_AS --CS bit = Case Sensitive
GO

SELECT *
FROM #MyTemp
WHERE Col1 = 'abC' --Only 1 record this time
GO

DROP TABLE #MyTemp
