I'm experimenting triggers functions in mysql. I got error as You have a sql syntax error at line 3. The code which I used,
use maas;
create trigger dummy_trigger after insert on dummy
for each row begin
declare cmd varchar(255);
declare result integer(10);
set cmd = concat('python /home/yogaraj/for_sql.py');
set result = sys_exec(cmd);
end;
Error Output:
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
Aim: I'm trying to execute a python file located in the home directory. I'm using mysql workbench.
If you use an SQL editor for this code then you have to specify a delimiter so that the inner commands of the create trigger code don't get parsed as individual statements.
However you can use the trigger pane in the table editor to create a trigger without all the decoration:
The blue dot left in the gutter shows that your statement is perfectly ok.

I need to create a trigger in sql server via R code for which I need to set my sql delimiter to //.
I tried doing the following:
dbExecute(con, "delimiter //")
dbExecute(con, "delimiter //\n")
dbExecute(con, "delimiter //\t")
I also tried the above scenarios with other DBI functions like
dbGetQuery and dbSendQuery
but I am getting the following error.
could not run statement: 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 'delimiter //' at line 1
It turns out that in order to execute an sql trigger through R using the DBI package, one does not need to set and unset the delimiter. We can directly execute the trigger command.
This is unlike what needs to be done while setting a triggers through SQL command line where, since the trigger syntax itself includes a semicolon ;, in order to avoid conflict with the default SQL delimiter which is also ; we temporarily set the delimiter to a lesser used special character such as // with a command such as
delimiter //
and then revert back to the default delimiter with
delimiter ;
which need not be done when trigger is executed through DBI package of R.
I am trying to send create procedure query from node js to MYSQL.
I am reading Mysql.proc table to get the stored procedure definitions.
Mysql code working fine when submitting from mysql client like workbench or hedis
Getting following error while submitting code from NodeJS

tried below code to pares sql in node
formattdSQL = formattdSQL.replace(/(?:\\[rtn]|[\r\t]+)+/g, ' ');
Query to get procedure
SELECT `name`, CONVERT(param_list USING utf8), CONVERT(body USING utf8)
INTO #spname, #spparams, #spbody
FROM mysql.proc WHERE `name` = 'USP_GET_ALL_STOCK_WITH_INDICATORS' AND db = v_oldDB;
SET #sql = CONCAT(#sql, '\r\n', 'DELIMITER //','\r\n','CREATE PROCEDURE `', v_newDB, '`.`', #spname, '`(', #spparams,')',#spbody, ' //', '\r\n','');
I expect that create procedure query should be executed successfully from node
The DELIMITER directive is not part of MySQL Server SQL. That is used only with interactive client utilities that parse an input stream or the contents of an on-screen text box into individual statements -- like workbench or (presumably) "hedis" (whatever that may be).
You don't use it when you are using a programming library to send a query.
Just send the procedure declaration as a single query. Send the USE statement as a separate query, before that.
First query:
USE qwe
(A trailing semicolon in the first query is not actually expected by the server but is allowed if you send it.)
Second query:
CREATE PROCEDURE ...
...
END
There should be no DELIMITER // before, nor // after. Those are all client-side constructs, not meaningful to the server.
There is no need to use your formattdSQL.replace(...) statement to remove newlines. That only serves to make your code unreadable, and isn't needed.
I know this question has been asked a bunch in different forms, but none of the ones I looked at (quite a bit) seemed to help me out in my specific case. I wrote a few functions and procedures and I always get the same error at the same spot. Here is my code:
DELIMITER |
DROP PROCEDURE IF EXISTS STUDENTS_BY_STATUS;
CREATE PROCEDURE STUDENTS_BY_STATUS (sts VARCHAR(10))
BEGIN
SELECT BannerId, Name FROM STUDENT WHERE Status = sts;
END |
DELIMITER;
This happens on all my procedures functions, this 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 'CREATE PROCEDURE STUDENTS_BY_STATUS (sts VARCHAR(10))
BEGIN
SELECT BannerId,' at line 2
On my other one its this:
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 'CREATE FUNCTION GoodGrade(letGrade VARCHAR(2)) RETURNS int
BEGIN
DECLARE v' at line 2
This happens whether or not I use | or // as the DELIMITER...can someone tell me what I'm doing wrong here? Thanks!
You've changed the delimiter, written a statement and then not delimited it according to your new definition
Change the line
DROP PROCEDURE IF EXISTS STUDENTS_BY_STATUS;
to
DROP PROCEDURE IF EXISTS STUDENTS_BY_STATUS |
Update
This wasn't obvious from the initial error message, but you have another error when you reset the Delimiter after the procedure definition. You need a space before the ';' on that one.
so change
DELIMITER;
to
DELIMITER ;
NB
The other use of ';' within your procedure definition is correct, because you want everything within the create statement to to be processed together.
I am trying to make a database that does some inventory checking, and I am working on some triggers to update everything as required. In this case, that I want to do is to take the current availability (disponibilidad) of an ingredient from the ingredients table, add to it how much is taken or added, and then save that value into the table stock_disponibilidad, as you can see from the trigger code I am trying to use.
DELIMITER $$
CREATE TRIGGER `update_disponibilidad_variacion` BEFORE INSERT ON `stock_disponibilidad`
FOR EACH ROW BEGIN
DECLARE old_disp DOUBLE DEFAULT 0;
SELECT disponibilidad INTO old_disp FROM ingredientes WHERE id = NEW.ingredientes_id;
NEW.disponibilidad = old_disp + NEW.variacion;
END$$
DELIMITER ;
However, whenever I execute the query to create the trigger, I get the following 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 '.disponibilidad = old_disp + NEW.variacion; END' at line 5
I've done everything I read about this issue, still without result. What am I doing wrong?
So I have this stored proc that will not get created when I run the file.
DELIMITER //
DROP PROCEDURE IF EXISTS msd.test_proc//
CREATE PROCEDURE msd.test_proc()
BEGIN
SELECT
'Hello proc'
FROM
msd.zipcode_lookup;
END//
DELIMITER ;
When I run this I get an error code 1064 at line 1 when I execute in RazorSQL. Here is the complete error message:
ERROR: 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 '//
CREATE PROCEDURE msd.test_proc()
BEGIN
SELECT
'Hello proc'
FROM ' at line 1
Error Code:1064
I've tried other variations and still get errors. I am sure this is something basic I am missing. I appreciate any help.
Thanks.
As stated on the RazorSQL website:
The DELIMITER statement is not part of the MySQL language. It is a command supported by certain MySQL tools. This command tells those MySQL programs to scan for a certain character that indicates the end of a query or statement.
RazorSQL does not support using the DELIMITER command. The SQL statement delimiter value used by RazorSQL can be changed using the preferences window. The default values is the semi-colon.
