How To Join Two Tables in a Single Query?

Two tables can be joined together in a query in 4 ways:

  • Inner Join: Returns only rows from both tables that satisfy the join condition.
  • Left Outer Join: Returns rows from both tables that satisfy the join condition, and the rest of rows from the first (left) table.
  • Right Outer Join: Returns rows from both tables that satisfy the join condition, and the rest of rows from the second (right) table.
  • Full Outer Join: Returns rows from both tables that satisfy the join condition, the rest of rows from the first (left) table, and the rest of rows from the second (right) table.
