hi,

Wondering why in below 3 queries, the first and the second returns results when in fact '123' is not equal to '123  '? MS SQL trim trialing spaces automatically?

1) select * from Employee where EmployeeID='123'
2) select * from Employee where EmployeeID='123  '
3) select * from Employee where EmployeeID='  123'
