Hi,

I have 2 queries and based on the number of rows in the 1st query, the 2nd query has to loop those many times.

Say in the 1st query if I have 6 rows, then my 2nd query has to loop 6 times.
Next time if the 1st query has 10 rows,then my 2nd query has to loop 10 times.

Iam new to this one and any help on how to do this would be highly appreciated!

Thanks a lot in advance!

Regards,
IP

If you only need to loop n times, the number of rows in the first query is in the &LINES variable.

Something like:
TABLE FILE CAR
SUM FST.COUNTRY
BY COUNTRY
END
-RUN

-REPEAT :LABEL FOR &I FROM 1 TO &LINES;
TABLE FILE CAR
SUM FST.CAR
END
-:LABEL


My guess is that you want to do something for each row in the first table though, in which case you're probably better served by a JOIN or a WHERE IN FILE.

Hi,

Thanks Dave and Wep5622 for the response and for the examples.


Actually I have 2 queries:
The 1st one would be like this :
select * from table1 ;
TABLE FILE table1
print
id
text noprint
on table hold as hld1
end
-run

Output : The result of the above query will be something like this :[Say it gives me 5 rows this time and next time if the data is more,then it would yield me 10 rows and so on]
100
200
300
400
500

This is my second query :
Select * from table2
where table2.text2 = text
and table2.id2 in (id);
end

Table file sqlout
print *
end

Now in the 2nd query, in the where condition, while Iam checking out for the id[where id2 in id] and this has to looped 5 times since we have got 5 rows in the 1st query.

Any thoughts/ideas on how to do this is greatly appreciated!
Thanks a lot in advance!
