Bug reference: 15200
Logged by: Lukas Eder
Email address: lukas.eder@gmail.com
PostgreSQL version: 10.4
Operating system: Windows
Description:
The manual states [1]:
> SQL:2008 introduced a different syntax to achieve the same result, which
PostgreSQL also supports. It is:
>
> OFFSET start { ROW | ROWS }
> FETCH { FIRST | NEXT } [ count ] { ROW | ROWS } ONLY
>
> In this syntax, to write anything except a simple integer constant for
start or count, you must write parentheses around it.
And as shown in this Stack Overflow question [2], it can be shown that the
standard syntax doesn't work with anything but constant literals, including
bind variables (which to me, are a kind of constant literal). This is
regrettable, the workaround when using this syntax from Java is to write:
OFFSET (?) ROWS FETCH FIRST (?) ROWS ONLY
Instead of (as in other databases):
OFFSET ? ROWS FETCH FIRST ? ROWS ONLY
This is also inconsistent with OFFSET .. LIMIT. The following works just
fine:
OFFSET ? LIMIT ?
I suggest relaxing this syntactic limitation and allowing for at least
constant literals AND bind variables in this syntax
