To select and join more than 2 tables in Oracle, you can use the following SQL syntax:

1
2
3
4
5
SELECT t1.column1, t2.column2, t3.column3
FROM table1 t1
JOIN table2 t2 ON t1.common_column = t2.common_column
JOIN table3 t3 ON t2.common_column = t3.common_column
WHERE <conditions>;


In this SQL query:

  • table1, table2, and table3 are the names of the tables you want to select data from.
  • t1, t2, and t3 are the aliases assigned to each table to make the query more readable.
  • common_column is the column that is used to join the tables together. Make sure that the common column exists in all the tables you are trying to join.
  • Replace column1, column2, and column3 with the specific columns you want to select from each table.


By using the JOIN keyword multiple times, you can join more than two tables together in Oracle.
