Description
I'm not quite sure what SQL standard thinks about it, but it looks somewhat inconsistent.
Both of these work:
MariaDB [test]> select 1; |
+---+ |
| 1 |
|
+---+ |
| 1 |
|
+---+ |
1 row in set (0.00 sec) |
|
|
MariaDB [test]> ( select 1 ); |
+---+ |
| 1 |
|
+---+ |
| 1 |
|
+---+ |
1 row in set (0.00 sec) |
But here the second one does not work:
MariaDB [test]> with x as ( select 1 ) select * from x; |
+---+ |
| 1 |
|
+---+ |
| 1 |
|
+---+ |
1 row in set (0.00 sec) |
|
|
MariaDB [test]> ( with x as ( select 1 ) select * from x ); |
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'x as ( select 1 ) select * from x )' at line 1 |
Another example. Both of these work:
MariaDB [test]> select exists ( select 1 ); |
+---------------------+ |
| exists ( select 1 ) | |
+---------------------+ |
| 1 |
|
+---------------------+ |
1 row in set (0.00 sec) |
|
|
MariaDB [test]> select exists ( ( select 1 ) ); |
+-------------------------+ |
| exists ( ( select 1 ) ) | |
+-------------------------+ |
| 1 |
|
+-------------------------+ |
1 row in set (0.00 sec) |
But here the second one does not work:
MariaDB [test]> select exists ( with x as ( select 1 ) select * from x ); |
+---------------------------------------------------+ |
| exists ( with x as ( select 1 ) select * from x ) | |
+---------------------------------------------------+ |
| 1 |
|
+---------------------------------------------------+ |
1 row in set (0.00 sec) |
|
|
MariaDB [test]> select exists ( ( with x as ( select 1 ) select * from x ) ); |
