CREATE PROCEDURE statement allows you to create a user-defined SQL procedure (stored procedure).

Syntax:

[ALTER | CREATE [OR REPLACE] | REPLACE] PROCEDURE | PROC procedure_name [parameters] 
 [AS | IS] 
 body
 
parameters:
  ([IN | OUT | INOUT | IN OUT] name data_type, ...)
  |
  (name [IN | OUT | INOUT | IN OUT] data_type, ...)
 
body:
  statement | expression | BEGIN statements END

Example:

Define a procedure and then call passing a parameter:

CREATE PROCEDURE set_message(IN name STRING, OUT result STRING)
BEGIN
 SET result = 'Hello, ' || name || '!';
END;
 
-- Now call the procedure and print the results
DECLARE str STRING;
CALL set_message('world', str);
PRINT str;
 
Result:
--
Hello, world!
