Re: syntax error at or near "ROWS"

Hi Dave

No, it still doesn't work with the wished statement OFFSET ? ROWS FETCH FIRST ? ROWS ONLY (because OFFSET ? LIMIT ? is non standard SQL)

The only reason I added the LIMIT-statement example was to show the differences in the behaviour

When $1 is "abc" it seems like the rest comes out as $2::int4 and $3::int4

When $1 is "abcde" it seems like rest comes out as $2 and $3

Only "abcde" works with FETCH FIRST-statement

Both "abc" and "abcde" works with the LIMIT-statement (it seems like the following parameters has different types though (as stated))
