Question

Return Successful

Dim user = "ravi"
        Dim pass = "admin"
        objcmd.CommandText = "Select * from ADMIN_INFO where ADMIN_ID='" & user & "' and ADMIN_PASS='" & pass & "'"

Return Successful

Dim user = "ravi"
        Dim pass = "ADMIN"
        objcmd.CommandText = "Select * from ADMIN_INFO where ADMIN_ID='" & user & "' and ADMIN_PASS='" & pass & "'"

After execution of query, both return successful, where as in table only ravi and admin is available. So, how can i check for case-sensitivity. Need help !!

Answer 1

CREATE TABLE #temp
(
    Password Varchar(2)
)
insert into #temp values('a')

First Approach

select Password  from #temp Where Password COLLATE Latin1_general_CS_AS  = 'A' 
select Password  from #temp Where Password COLLATE Latin1_general_CS_AS  = 'a' 

Second Approach

select Password  from #temp Where cast(Password as varbinary(2))  = cast('A' as varbinary(15)) 
select Password  from #temp Where cast(Password as varbinary(2))  = cast('a' as varbinary(15))

drop table #temp
