Embedded SQL into a DS of multiple DS


I am trying to perform a FETCH into a DS, with that data structure being defined smaller DSs, each DS being the fields in a table that the SQL SELECT selects from.

Does anyone know if it is possible to do something like this:

D JL0099 E DS ExtName(JBTJL0099 : *ALL)
D JL0110 E DS ExtName(JBTJL0110 : *ALL)
D JL0120 E DS ExtName(JBTJL0120 : *ALL)

dcl-ds DS_ALL dim(100) qualified;
d1_ds likeds(jl0099);
d2_ds likeds(jl0110);
d3_ds likeds(jl0120);
end-ds;


then:

exec sql fetch from [cursor] for 100 rows into :ds_all

The SQL is a join of 4 tables, but I can't get this to compile. I get the "SQL0312 Variable DS_ALL not defined or not usable" error. Can you fetch into a DS of DSs?

Thank you,

Doug
