In SQL Server XYZ & xyz are treated as same value

Dear All,

In ORACLE, the values 'XYZ' and 'xyz' are treated as different values and I can enter two records with the primary key field having values 'XYZ' and 'xyz'.

But In SQL Server, 'XYZ' and 'xyz' or 'xYz' or 'Xyz' etc are treated as same value. So, when I try to insert 'xyz' after inserting a record with 'XYZ' as value of the primary key field, it gives me the duplicate record error. How to solve this problem?
I want it to work the SQL Server same as Oracle according to our requirement.

Can any one of you Please help me out in this regard?

Regards,
Sat.oracle is case sensitive, by default sql is not...
you can either change your whole installation to be case sensitive
or just make that primary key column case sensitive by running the command below...

alter table tablename
alter column columnname datatype
collate SQL_Latin1_General_Cp1_CS_AS
