MySQL create stored procedure syntax with delimiter

Question

I am trying to create a stored procedure in MySQL using a delimiter like this   use am   DELIMITER     CREATE PROCEDURE addfields   BEGIN   DECLARE done INT DEFAULT FALSE    DECLARE acc INT 16     DECLARE validId INT DEFAULT 0   END     DELIMITER     It gives me an error    1304 - PROCEDURE addfields already exists   What is the proper syntax for making a stored procedure with a delimiter and dropping it if it exists first

I have created a simple MySQL procedure as given below:

DELIMITER //
CREATE PROCEDURE GetAllListings()
 BEGIN
 SELECT nid, type, title  FROM node where type = 'lms_listing' order by nid desc;
END //
DELIMITER;

Kindly follow this. After the procedure created, you can see the same and execute it.

Getting started with stored procedure syntax in MySQL  using the terminal   1   Open a terminal and login to mysql like this  el apollo    mysql -u root -p Enter password   Welcome to the MySQL monitor   Commands end with   or  g  mysql gt    2   Take a look to see if you have any procedures  mysql gt  show procedure status   ----------- --------------- ----------- --------- --------------------- --------------------- --------------- --------- ---------------------- ---------------------- --------------------    Db          Name            Type        Definer   Modified              Created               Security type   Comment   character set client   collation connection   Database Collation    ----------- --------------- ----------- --------- --------------------- --------------------- --------------- --------- ---------------------- ---------------------- --------------------      yourdb    sp user login   PROCEDURE   root      2013-12-06 14 10 25   2013-12-06 14 10 25   DEFINER                   utf8                   utf8 general ci        latin1 swedish ci     ----------- --------------- ----------- --------- --------------------- --------------------- --------------- --------- ---------------------- ---------------------- --------------------  1 row in set  0 01 sec   I have one defined  you probably have none to start out  3   Change to the database  delete it  mysql gt  use yourdb  Database changed  mysql gt  drop procedure if exists sp user login  Query OK  0 rows affected  0 01 sec       mysql gt  show procedure status  Empty set  0 00 sec        4   Ok so now I have no stored procedures defined   Make the simplest one  mysql gt  delimiter    mysql gt  create procedure foobar       - gt  begin select  hello   end   Query OK  0 rows affected  0 00 sec   The    will communicate to the terminal when you are done entering commands for the stored procedure   the stored procedure name is foobar   it takes no parameters and should return  quot hello quot   5   See if it s there  remember to set back your delimiter    mysql gt  show procedure status   - gt    - gt    Gotcha   Why didn t this work   You set the delimiter to    remember   Set it back to   6   Set the delimiter back and look at the procedure  mysql gt  delimiter   mysql gt  show procedure status   ----------- -------- ----------- ---------------- --------------------- --------------------- --------------- --------- ---------------------- ---------------------- --------------------    Db          Name     Type        Definer          Modified              Created               Security type   Comment   character set client   collation connection   Database Collation    ----------- -------- ----------- ---------------- --------------------- --------------------- --------------- --------- ---------------------- ---------------------- --------------------    yourdb      foobar   PROCEDURE   root localhost   2013-12-06 14 27 23   2013-12-06 14 27 23   DEFINER                   utf8                   utf8 general ci        latin1 swedish ci     ----------- -------- ----------- ---------------- --------------------- --------------------- --------------- --------- ---------------------- ---------------------- --------------------  1 row in set  0 00 sec        7   Run it  mysql gt  call foobar     -------    hello    -------    hello    -------  1 row in set  0 00 sec  Query OK  0 rows affected  0 00 sec   Hello world complete  lets overwrite it with something better  8   Drop foobar  redefine it to accept a parameter  and re run it  mysql gt  drop procedure foobar  Query OK  0 rows affected  0 00 sec   mysql gt  show procedure status  Empty set  0 00 sec   mysql gt  delimiter    mysql gt  create procedure foobar  in var1 int      - gt  begin select var1   2 as result      - gt  end   Query OK  0 rows affected  0 00 sec   mysql gt  delimiter   mysql gt  call foobar 5    --------    result    --------         7    --------  1 row in set  0 00 sec  Query OK  0 rows affected  0 00 sec   Nice   We made a procedure that takes input  modifies it  and does output   Now lets do an out variable  9  Remove foobar  Make an out variable  run it  mysql gt  delimiter   mysql gt  drop procedure foobar  Query OK  0 rows affected  0 00 sec   mysql gt  delimiter    mysql gt  create procedure foobar out var1 varchar 100       - gt  begin set var1  quot kowalski  what s the status of the nuclear reactor  quot       - gt  end   Query OK  0 rows affected  0 00 sec    mysql gt  delimiter   mysql gt  call foobar  kowalski status   Query OK  0 rows affected  0 00 sec   mysql gt  select  kowalski status   -----------------------------------------------------     kowalski status                                       -----------------------------------------------------    kowalski  what s the status of the nuclear reactor     -----------------------------------------------------  1 row in set  0 00 sec   10   Example of INOUT usage in MySQL  mysql gt  select  ricksays  into  msg  Query OK  1 row affected  0 00 sec    mysql gt  delimiter    mysql gt  create procedure foobar  inout msg varchar 100   -
