Michael;

I do this type of thing quite often:
D data DS Qualified
D Dim(100)
D Based(dataBase)
D entryId 20I 0
D field1 10A
D field2 10A
D field... 10A
D fieldN 10A
D processName 25A

D example DS Qualified
D Dim(100)
D entryId 20I 0
D field Like(data.field1)
D Dim(N)
D processName 25A

In your code initialize the dataBase pointer dataBase = %Addr(example),
fetch into the data structure and you can access the fields like
example(x).field(y). SQL represents data as a record, but you can redefine
the representation anyway you need with an appropriate structure.

Subject: SQL select into [array]?

I am looking for an elegant way to code an embedded SQL statement that
selects into, where the host target is an array.

As in:

Select Field1, Field2, Field3
into :MyArray(1), :MyArray(2), :MyArray(3)
From *libl/MyTable

Where Key1 = :MyKey;



... or even

Fetch from MyCursor
into :MyArray(1), :MyArray(2), :MyArray(3);



Apparently SQL syntax does not know about using "(1)", "(2)", and "(3)"
to designate the target array elements. Is there a way to code that to be
acceptable to SQL and to the V5R4 pre-compiler?



I'm hoping not to have to dump the results into a data structure, because I
ultimately need to reference the results by an index, and it would be great
to get them to load directly into the array if possible.



If only I knew the trick...



Thanks
Michael Koester
