There is nothing wrong with the syntax per se
That JOIN is awful though ... consider setting up a proper primary key / foreign key relationship

By "it's not working" I take it to mean that it is not returning any results, but that it does return results if you remove and b.vcode=001

Firstly - why the preceding zeroes ... if columns vcode and distt are numeric then write this as

SQL

where a.distt=17 and a.block=1 and b.vcode=1

However if they are char or varchar then write it like this

where a.distt=17 and a.block='01' and b.vcode='001'

After that, if you are still not getting results back then there is no matching data on your table. Run it without that last condition but adding vcode to the SELECT - have a good look at the results, you'll find that none of the records have vcode = 1

Hi Bindash,

Hmm pls check the column does have value "001" or something else.
I think it may have be like .001
