mysql - union with creating demarcated field
- by Qiao
I need UNION two tables with creating new field, where 1 for first table, and 2 for second.
I tried
(
SELECT field, 1 AS tmp
FROM table1
)
UNION
(
SELECT field, 2 AS tmp
FROM table2
)
But in result, tmp field was full of "1".
How it can be implemented?
