I have table where there are two rows with same value , but one is in small letter and one is in Caps, like EMPLID = 'RX0001B' and 'RX0001b'. Now when I query the table , Select * from table XXXX where EMPLID = 'RX0001B', it retrieves both the rows. How to avoid this? I am new to MSS 2008.

Look up COLLATE in books on line or in the management stuido help

Here's an example to get you started


DECLARE @collations TABLE (
	[vala] VARCHAR(255) COLLATE LATIN1_GENERAL_CI_AI -- Case Insensitive, Accent Insensitive
	, [valb] VARCHAR(255) COLLATE LATIN1_GENERAL_CS_AS -- Case sensitive, Accent Sensitive
	)

INSERT INTO @collations ([vala], [valb])
          SELECT 'aaaa', 'bbBbb'
UNION ALL SELECT 'AAAA', 'bBBBB'

SELECT * FROM @collations WHERE [vala] = 'aaaa'
SELECT * FROM @collations WHERE [vala] = 'aaaa' COLLATE LATIN1_GENERAL_CS_AS

SELECT * FROM @collations WHERE [valb] = 'bbbbb'
SELECT * FROM @collations WHERE [valb] = 'bbBbb' COLLATE LATIN1_GENERAL_CI_AI

Try this too

select * from table_name where cast(column_name as varbinary)= cast(@value as varbinary)
