when trying to create a simple procedure in mysql 5.1.47-community it fails everytime i've tried everything!
even simple things like this!
DELIMITER //
CREATE PROCEDURE two ()
begin
SELECT 1+1;
end;
//
The error is
ERROR: Error 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'mydb' at line 1
The error message you've given doesn't correspond to the code you've pasted. You're referring to "mydb" somewhere in the SQL you're running yet it's not anywhere in the code you've put in the question.
The code you've given should work fine as I see no syntax errors, you may just need to give it a database to work on ("test" in my case here, perhaps it should be "mydb" for you?).
DELIMITER //
CREATE PROCEDURE test.two ()
begin
SELECT 1+1;
end;
//
DELIMITER ;
CALL test.two;
However, I suspect the error you're getting is become of a line in your SQL that you're not showing us.
EDIT
It could perhaps be the delimiter command. You're changing the delimiter to // rather than the default ;. So perhaps you've run that command (and changed the delimiter for your session to //), and then tried to run USE mydb; where the ; is no longer recognised as a valid delimiter for your session, and that could be giving you the error. Try putting delimiter ; before your use line and see if that helps (and then use it again after you've defined your stored procedure so you can call it). This is just a theory though, as I'm not sure of the intricacies of the delimiter command.
Remove the final delimiter "end" instead "end;"
I had the same problem using heidisql as the fronted to enter the SQL. My first attempt was:
CREATE PROCEDURE Add_Two (IN someNumber int, OUT result INT)
BEGIN
SELECT someNumber +2 INTO result;
END
and this resulted in SQL ERROR (1064) because i was not aware that when using a client program a delimiter is needed to define the stored procedures.
After changing the above to this:
DELIMITER //
CREATE PROCEDURE Add_Two(IN someNumber int, OUT result INT)
BEGIN
SELECT someNumber +2 INTO result;
END
//
It worked out.
Example to call it
SET #someNumber :=8;
CALL Add_Two(#someNumber, #result);
SELECT #result;

What is wrong in the following code (please forgive me for very basic question)
Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 3
CREATE PROCEDURE `getCleanData` ()
BEGIN
replace into CLEAN_TBL SELECT mycolumn FROM DIRTY_TBL;
END;
You need to change the DELIMITER to something else than the default ;.
A DELIMITER tells whe the command ends. By default the delimiter is ;. As procedure itself uses ; in it's syntax (end of statement), you need to change the DELIMITER to something else to that the full procedure code will be executed.
Step 01: change server delimiter -->
DELIMITER //
Step 02: create your procedure with new delimiter you used in step 01
CREATE PROCEDURE `getCleanData` ()
BEGIN
replace into CLEAN_TBL SELECT mycolumn FROM DIRTY_TBL;
END
//
DON'T TRY TO REVERT THE DELIMITER
Right way to do from experts are welcome, because I am not sure what is the right way.....but I feel not having the default delimiter for CREATE PROCEDURE is wrong.
Very new to the environment, I have a question about a line that's added to the end of my code. The guide I'm following is:
http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/
If anyone has a better one regarding MySQL stored procedures, I'm all ears.
Before I ask, this is the environment I'm using:
OS: Windows 7 / WAMP (MySQL 5.5.24) / MySQL Workbench
I'm instructed to define a delimiter; in my case I'm sticking with the default '$$.'
The stored procedure I created is:
DELIMITER $$
CREATE PROCEDURE test.`p2` ()
LANGUAGE SQL
DETERMINISTIC
COMMENT 'Adds "nson" to first and last names in the record.'
BEGIN
SELECT 'Hello World';
END $$
When I apply this stored procedure and I get the review screen, I see a new line of code added;
At the bottom:
DELIMITER ;
This lats line; is it added because the DELIMITER statement announces a block within which the defined delimiters ($$) can be used and thus closes the block in the end?
When using the builtin procedure editor, MySQL Workbench adds a few extra commands:
USE `test`; // <----------
DROP procedure IF EXISTS `p2`; // <----------
DELIMITER $$
USE `test`$$ // <----------
CREATE PROCEDURE test.`p2` ()
LANGUAGE SQL
DETERMINISTIC
COMMENT 'Adds "nson" to first and last names in the record.'
BEGIN
SELECT 'Hello World';
END $$
DELIMITER ; // <----------
Those commands are not strictly related to the stored procedures syntax, they're merely a commodity—other MySQL clients (such as HeidiSQL or the official command line utility) will not add them. The last delimiter change is probably a reset to avoid problems in future statements on the same connection.
You need to change the delimiter in order to instruct the client about where the procedure code starts and end. The problem is that the procedure body is normally a collection of SQL statements so omitting the delimiter change would make MySQL think that you are attempting to run a series of statements, the first of which would be this:
CREATE PROCEDURE test.`p2` ()
LANGUAGE SQL
DETERMINISTIC
COMMENT 'Adds "nson" to first and last names in the record.'
BEGIN
SELECT 'Hello World';
With DELIMITER $$ you are telling MySQL that your full statement goes from CREATE to END. It's just syntactic sugar: DELIMITER is not even a SQL keyword. HeidiSQL, for instance, provides a GUI with a text box where you write the procedure body, thus you don't need the DELIMITER workaround.
I'm running Workbench 5.2.47.
I have a long procedure I wrote with basic data checking. If a record did not exist in the database, the record would be inserted.
The procedure saved with no problems, but MySQL 5.5 throws an error when I try running it.
It is long, and has a lot of company sensitive data in it, or I would post it here.
I am trying to debug the procedure by executing small chunks of the code, but I can't seem to get Workbench to allow anything I try.
MySQL shows how to create a stored procedure in 5.1.5 Working with Stored Procedures.
Let me show you something very basic I am trying to write:
DELIMITER $$
DROP PROCEDURE IF EXISTS my_test;
CREATE PROCEDURE my_test()
BEGIN
SELECT * FROM Employees;
END $$
DELIMITER ;
With that, Workbench gives me the error, "syntax error, unexpected CREATE, expecting $end".
I don't understand that, but I need to get something done, so I am moving on.
I make a simpler query:
SET #Count=(SELECT Count(*) FROM tbl_object_users WHERE username='jp2code');
IF (#Count < 1) THEN
INSERT INTO tbl_object_users (username, date_time) VALUES ('jp2code', NOW());
END IF;
Again, I get an error, this time on my IF statement.
Next, I go into PhpMyAdmin to try running something from there using its database:
SET #Count=Count(id) FROM `tbl_object_users` WHERE `username`='jp2code';
It, too, tells me I have an error in my SQL syntax.
I did download and install the newest Workbench 6, but it did not solve the problem - and I did not like the interface, so I uninstalled it and went back to Workbench 5.2.
What is going on? SQL isn't that hard, so what is with these hurdles?
Problem with this:
DELIMITER $$
DROP PROCEDURE IF EXISTS my_test;
CREATE PROCEDURE my_test() ...
is that MySQL isn't seeing the semicolon at the end of the DROP PROCEDURE statement line as the end of the statement. This is because the preceding line told MySQL that the statement terminator was something other than a semicolon. You told MySQL that statements were going to be terminated with two dollar signs. So MySQL is reading the DROP PROCEDURE line, looking for the statement terminator. And the whole blob it reads is NOT a valid MySQL statement, it generates a syntax error.
The fix: either move the DROP PROCEDURE line before the DELIMITER $$ line; or terminate the DROP PROCEDURE statement with the specified delimiter rather than a semicolon.
The second problem you report is a syntax error. That's occurring because MySQL doesn't recognize IF as the beginning of a valid SQL statement.
The IF statement is valid only within the context of a MySQL stored program (for example, within a CREATE PROCEDURE statement.)
The fix: Use an IF statement only within the context of a MySQL stored program.
The third problem you report is also a syntax error. That's occurring because you don't have a valid syntax for a SET statement; MySQL syntax for SET statement to assign a value to user variable is:
SET #uservar = expr
MySQL is expecting an expression after the equals sign. MySQL is not expecting a SQL statement.
To assign a value to a user variable as the result from a SELECT statement, do the assignment within the SELECT statement, for example:
SELECT #Count := Count(id) FROM `tbl_object_users` WHERE `username`='jp2code'
Note that the assignment operator inside the SELECT statement is := (colon equals), not just =.
try this
DELIMITER $$
DROP PROCEDURE IF EXISTS my_test$$
CREATE PROCEDURE my_test()
BEGIN
SELECT * FROM `customer_to_pay`;
END $$
DELIMITER ;
I have the following piece of statement entered into MySQL5.6 Command Line Client. However, the following error was received. I haven't even been able to add in END// Delimiter; after the select statement.
At the same time, i was wondering after the stored procedure has been created successfully, how do i CALL the stored procedure without the command line but using java codes.
Kindly assist. Greatly appreciated!
give space between delimiter and //. After your select statement write end; on next line and // at last line (after end; in next new line)
delimiter //
create procedure GetUStocks()
Begin
Select * From buystocks;
end;
//
mysql> delimiter //
mysql> CREATE PROCEDURE GetUStocke()
-> BEGIN
-> SELECT * FROM buystocks ;
-> END//
You need a space between DELIMITER and the symbol you are changing the delimiter to.
mysql> DELIMITER //
The clue that it worked should be that you get another mysql> prompt instead of the "unfinished command" prompt ->.
Re your comment, if you need to call a stored procedure from a Java application, refer to the manual on callable statements: http://dev.mysql.com/doc/refman/5.6/en/connector-j-usagenotes-statements-callable.html
Well, seriously, I was Shocked and still am upon this accidental discovery.
It's simply because you are not using the delimiter that you have defined for ending the procedure.
Here let me attach two snippets that will help illustrate what is generating the error.
