PL/pgSQL

i've got a simple plsql function and this line is wrong:

   EXECUTE ''SELECT INTO lp MAX('' || column || '') AS MX FROM '' || table
|| '';'';

with error message:

"parse error at or near 'INTO' "

it seems like it don't recognize SELECT INTO - but what's wrong?

                                                    Thaks, Wojtek

Try

EXECUTE ''SELECT MAX(''||column||'') INTO lp FROM '' || table;

This should work but haven't tested it.

Normally with select into though is is

select foo into bar from aa where id = _id;

How about

 EXECUTE ''SELECT MAX('' || column || '') AS MX INTO lp FROM '' || table

?

Cheers,

In PL/pgSQL, you have to use CREATE TABLE ... AS because INTO has
another meaning in PL/pgSQL.
