Re: How do I do a SQL select into a data structure when specifying fields?

You're doing it wrong...

You shouldn't be reading with SQL into a DS that then gets returned as a
result set.

All you need to do is declare and open a cursor

exec SQL
declare C1 cursor for
Select fielda, fieldb, fieldc
From myTable;

exec SQL
open C1;

return;

By virtue of being left open, the cursor will be returned as the result set.

Personally, I prefer to build such stored procedures directly in SQL rather
than RPG.

Compilers tells me SL0312 T_data is not defined or usable.

What am I doing wrong or how would I do this?

I do not want to read 1 record at a time.

As others noted, FETCH multiple rows. But if the data for the

result-set is known to be necessarily limited [e.g. 100x320], then the data
can be returned as one row, so in effect, the above SELECT INTO could be
accomplished; the contiguous data is then /viewed/ by the program as
DIMensioned proportionally. A recursive query can easily enough
concatenate the originally expected-as multiple-row result-set as just one
row.
