== 1. Ordering by computed column ==
|
||
|
|
Examples: select rand() from T order by 1;
|
||
|
|
select 1 from T order by 1;
|
||
|
|
MySQL: +
|
||
|
|
SQLite: -
|
||
|
|
PostgreSQL: ?
|
||
|
|
|

|
|
== 2. Using more than just "*" in the column list ==
|
||
|
|
Example: select *, 1 from T;
|
||
|
|
MySQL: -
|
||
|
|
SQLite: +
|

PostgreSQL: ?
