To join four tables in MySQL, you can use the JOIN clause multiple times with appropriate join conditions. Here is an example:
1 2 3 4 5 |
SELECT * FROM table1 JOIN table2 ON table1.column1 = table2.column2 JOIN table3 ON table2.column3 = table3.column4 JOIN table4 ON table3.column5 = table4.column6; |
In this example, table1
, table2
, table3
, and table4
are the names of the four tables you want to join. column1
, column2
, column3
, column4
, column5
, and column6
are the columns used to relate the tables.
