Обсуждение: potential bug in error message in with clause
Hi,
today on IRC there was a strange problem shown. The small working example looks like this:
x=# with x as (insert into a(t) values('1') returning *) select * from x;
t
---
1
(1 row)
x=# with x (insert into a(t) values('1') returning *) select * from x;
ERROR: syntax error at or near "into"
LINE 1: with x (insert into a(t) values('1') returning *) select * f...
^
The initial code was run on 9.2; I've checked that on 9.4devel.
The error message is really not useful, as there is missing "as" after "with x". There is no problem with "into".
regards
Szymon

I don't think that's a bug.
A parenthesis after with_query_name introduces the list of column
names for the WITH-query, and it complains that there is no comma
or closing parenthesis after "insert".
