Re: Limits of SQL SET variable

[Charles Wilt <charles.wilt@xxxxxxxxx>]

All you need is

INSERT INTO liba/doc#file
SELECT  loc,  petable.enddate,  outlet,
        docfunc(:loc, :outlet, :enddate)
  FROM  libb/sales  JOIN  libx/petable
       ON  sales.year = petable.year
    AND  sales.period = petable.period
GROUP BY petable.enddate,loc,outlet
ORDER BY 1,2,3

Optionally, you could have
      docfunc(:loc, :outlet, :enddate) as docnum

To give the result column a name, but the names don't matter to the insert.
 Only size/type.
