Question

I have two tables and want to return both table’s rows. Both tables do not have any relation.

Table 1 has columns userid, name, and other columns… and Table 2 has only two columns id, name.

I want both table results in one query result set.

Table results:

userid name and other columns from Table 1.
id     name and NULL, NULL should show as Table 2 do not have extra columns.

Answer 1

Use a union

select userid, name, col1, col2, col3 from table1
union all
select id, name, null, null, null from table2
