(OP)
I execute this statement:
select table1.column1, table2.column2 from table1, table2;

and recieve this result:
col1val1     col2val1
col1val2     col2val1
col1val1     col2val2
col1val2     col2val2

what do i change in the above statement, so that i get this result:
col1val1     col2val1
col1val2     col2val2

thanks.

RE: unique distinct

You have written a cross join because you specified no join fields. You need to write an inner join. Suggest you read up on joins before going any further.

RE: unique distinct

And just so you know, that is referred to as a Cartesian. It means that for ever row in table1, it matches it to a row in table 2. That is why you are getting so many results.
