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.
