Is there an easy way to rename a table in a MySQL procedure?

MySQLMySQLi Database

Yes, use the ALTER command with RENAME. Let us first create a table −

mysql> create table DemoTable1859
     (
     Id int
     );
Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1859 values(101);
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1859 values(102);
Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1859;

This will produce the following output −

+------+
| Id   |
+------+
|  101 |
|  102 |
+------+
2 rows in set (0.00 sec)

Following is the query to create a stored procedure and rename the table name −

mysql> delimiter //
mysql> create procedure alter_table_name_sp()
     begin
     alter table DemoTable1859 rename exampleTable;
     end
     //
Query OK, 0 rows affected (0.00 sec)
mysql> delimiter ;

Call the stored procedure using call command −

mysql> call alter_table_name_sp();
Query OK, 0 rows affected (0.00 sec)

Check the table name has been changed or not using select command −

mysql> select * from exampleTable;

This will produce the following output −

+------+
| Id   |
+------+
|  101 |
|  102 |
+------+
2 rows in set (0.00 sec)
