How to Join Tables with the Outer Join Operator in SQL

The OUTER JOIN operator is used in SQL to combine data from two or more tables. The OUTER JOIN operator returns all the records from the left table, plus any matching records from the right table. If there are no matches, then the left table is returned empty.

The OUTER JOIN operator is useful for combining data from two or more tables when you want to include all of the data from one table, even if there are no matches in the other table.

The OUTER JOIN operator can be used with the INNER JOIN and FULL JOIN operators

The following example shows how to use the OUTER JOIN operator to combine data from two tables:

  • SELECT *
  • FROM Table1
  • OUTER JOIN Table2
  • ON Table1.ID = Table2.ID;

In this example, the operator will return all of the records from the Table1 table, plus any matching records from the Table2 table. If there are no matches, then the left table (Table1) is returned empty.
