Hi,

I have 2 tables and I want to select some data from them based on a common records. In the query, one of the column must be calculated as product of one field from table 1 and one field from table 2.

When I run the query, i get one row with the data without calculation, and one with calculation

The query is this:

SELECT A.CODSUB, A.CODOB, A.CODSBB, A.CANT*B.CANT FROM LSUBANS A,X01 B

WHERE A.CODSUB=B.CODSBB

LSUBANS

CODSUB  CODOB  CODSBB  CANT

SB3               EL8                         3

X01

CODSUB  CODOB  CODSBB  CANT

SB4                            SB3             3

the result of query had to be:

CODSUB  CODOB  CODSBB  CANT

SB3               EL8                         9

instead is:

CODSUB  CODOB  CODSBB  CANT

SB3               EL8                         3

SB3               EL8                         9

What I do wrong?

Thanks
