Hi,
MySQL has insert into function and sub select (mysql style) but I
could not conclude these function togethter.
If I want to select not existing row in 2 table, I used:
SELECT table1.* FROM table1 LEFT JOIN table2 ON
table1.id=table2.id where table2.id is null
then I'd like to insert the result row back into table2 by this SQL:
insert into table2 SELECT table1.* FROM table1 LEFT JOIN table2 ON
table1.id=table2.id where table2.id is null
it got this error:
ERROR 1066: Not unique table/alias: 'table2'
How could I fixed this problem??
