Question

How can I join table a and table b and get records for each? Not an actual join… not sure what this is called.

So if I have 3 records in a, and 5 records in b, I want 8 records back.

In a record for a, all b fields can be null. In a record for b, all a fields can be null.

edit: My tables have different fields.

Error Code: 1222. The used SELECT statements have a different number of columns

Answer 1

Like the others mentionned, you need an union

SELECT intColumn, varcharColumn, intColumn FROM a
UNION
SELECT intColumn, varcharColumn, 0 FROM b

but you must have the same number of columns and they must also have similar data types.

Here’s a good tutorial about it

Also, if you want columns that are not in both tables, you can fill with nulls or constants.
