Re: Writing lots of records

[Charles Wilt <charles.wilt@xxxxxxxxx>]

Changing to SQL would help if you used a multi-row insert.

Inserting 500,1000 or 1500 records at a time would be considerably quicker
than RPG's 1 row at a time.

dcl-ds mydata dim(500);
  ...
end-ds;

exec sql
  insert into my table for :nbrRows values(:mydata);
