How to resolve this query sql this? -


i have query sql this

select fname, idcard, left(idcard,3) kodecard tcard kodecard = '200'

how resolve query? have 2 column (fname, , idcard) , want filter first 3 digits in idcard column.

could give me solution?

just use left function in condition

select fname, idcard tcard left(idcard,3) = '200'

you may use like well. 

select fname, idcard tcard idcard '200%'

this solution better since allows query processor use index (if available).
