Description
Queries of the following type (auto-generated) work in MariaDB 10.1.33, but fail in 10.2.17 and 10.3.8:
INSERT INTO td SELECT now() WHERE 1=1;
|
It is common for the code to auto add the "WHERE 0=1" or "WHERE 1=1".
10.1:
mysql> CREATE TABLE `td` (
|
-> `t` datetime DEFAULT NULL
|
-> ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_general_cs;
|
Query OK, 0 rows affected (1.87 sec)
|
|
|
mysql> insert into td select now() where 1=1;
|
Query OK, 1 row affected (0.02 sec)
|
Records: 1 Duplicates: 0 Warnings: 0

1 row in set (0.00 sec)

In both 10.2 and 10.3, we see:
mysql> CREATE TABLE `td` (
|
-> `t` datetime DEFAULT NULL
|
-> ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_general_cs;
|
Query OK, 0 rows affected (1.67 sec)
|
|
|
mysql> insert into td select now() where 1=1;
|

One strange thing about 10.1 is that the sub-query ("select now() where 1=1;") fails when issued by itself, but works when it is part of the INSERT INTO:
mysql> select now() where 1=1;
