I've been searching for a while and I'm not sure if this is allowed in mysql.
I know this is allowed in mysql
Insert into 'table' (column1, column2, column3) Select val1, val2, val3 From sometable
Also this
Insert into 'table' (column1, column2, column3) Values (val1, val2, val3), (val1, val2, val3)
I am not sure if this is allowed though:
Insert into 'table' (column1, column2, column3) Select val1, val2, val3 From sometable, Select val1, val2, val3 From sometable
Obviously that gave me an error, is that allowed in mysql?
You can try it, and it will fail. Use union all
instead of ,
:
Insert into table (column1, column2, column3)
Select val1, val2, val3 From sometable
union all
Select val1, val2, val3 From sometable;
I assume the single quotes were there for some sort of effect, because you say that the first two queries actually work.
