Please tell me how can I check existing data before insert new value.
for example: in my database has this value:   Sample Test.
So when user input new values like: sample test, Sample Test, Sample test, sample Test. SQL will prevent it.

How can I do?
Please help me!

use COLLATE SQL_Latin1_General_CP1_CI_AS - for non- case senstive search
IF NOT EXISTS (SELECT 1 FROM TableName WHERE feildName COLLATE SQL_Latin1_General_CP1_CI_AS = 'Sample Test' )
BEGIN
 
	-- Insert Statement
 
END
