View stored procedure/function definition in MySQL?

MySQLMySQLi Database

To view stored procedure/function definition in MySQL, you can use show command. The syntax is as follows −

SHOW CREATE PROCEDURE yourProcedureName;

To understand the above syntax, you can create a procedure and check that definition. Let us create a stored procedure −

mysql> delimiter //
mysql> create procedure AllRecords()
   -> begin
   -> select *from student;
   -> end //
Query OK, 0 rows affected (0.24 sec)

You can call the stored procedure with the help of call command. The query is as follows −

mysql> delimiter ;
mysql> call AllRecords();

The following is the output −

+------+-------+
| id   | Name  |
+------+-------+
| 1    | John  |
| 2    | Bob   |
| 3    | Smith |
| 6    | John  |
+------+-------+
4 rows in set (0.14 sec)

Query OK, 0 rows affected (0.18 sec)

Now you can check the definition with the help of above syntax which we discussed in the beginning. The query is as follows −

mysql> show create procedure AllRecords;

Here is the output −

+------------+--------------------------------------------+-----------------------------------------------------------------------+----------------------+----------------------+--------------------+
| Procedure  | sql_mode                                   | Create Procedure                                                      | character_set_client | collation_connection | Database Collation |
+------------+--------------------------------------------+-----------------------------------------------------------------------+----------------------+----------------------+--------------------+
| AllRecords | STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION | CREATE DEFINER=`root`@`%` PROCEDURE `AllRecords`() begin select *from student;end | utf8     | utf8_general_ci      | utf8mb4_unicode_ci |
+------------+--------------------------------------------+-----------------------------------------------------------------------+----------------------+----------------------+--------------------+
1 row in set (0.00 sec)

To check the function definition in MySQL, you can use function in place of procedure. The syntax is as follows: −

SHOW CREATE FUNCTION yourFunctionName;
