Creating a stored procedure with utf8 strings - mysql

I have a stored procedure with some Cyrillic strings inside. I want to check a table with a char column if the column contains some specific strings, some of them in Cyrillic. The problem seems to be that I cannot create the procedure with those strings.
SET NAMES utf8;
delimiter //
drop procedure if exists testutf8
//
create procedure testutf8()
begin
select 'ξενοδοχια';
end
//
delimiter ;
call testutf8();
Returns
?????????
show create procedure testutf8;
returns
Procedure testutf8
sql_mode STRICT_TRANS_TABLES
Create Procedure "CREATE DEFINER=xxx#% PROCEDURE testutf8() begin select '?????????'; end"
character_set_client utf8
collation_connection utf8_general_ci
Database Collation latin1_swedish_ci
So despite me using SET NAMES UTF8; the server turns my code into latin1 it seems. How can I fix this?

In store procedure input variable added
CHARSET utf8
So it look like this:
CREATE DEFINER=`root`#`%` PROCEDURE `post_content`(IN postName varchar(255), IN contentEn longtext, IN contentAR longtext CHARSET utf8, IN contentKU longtext CHARSET utf8)
...

adding ?characterEncoding=utf8 to the server url did the trick.

Try using
delimiter //
drop procedure if exists testutf8
//
create procedure testutf8()
begin
select CAST('ξενοδοχια' AS CHAR CHARACTER SET utf8);
end
//
delimiter ;

ERROR 1415: 1415: Not allowed to return a result set from a trigger

I have created a stored procedure with one argument. I have made a trigger to call stored procedure. Trigger calls stored procedure on change of a column value a table(device_session1).If is_active is updated to 'No' then trigger calls stored procedure. I pass that column value in stored procedure and procedure prints it but its giving error when i update column value.
Table-
CREATE TABLE `device_session1` (
`id` varchar(75) CHARACTER SET latin1 COLLATE latin1_swedish_ci NOT NULL,
`is_active` varchar(50) CHARACTER SET latin1 COLLATE latin1_swedish_ci DEFAULT NULL,
PRIMARY KEY (`id`));
insert into device_session1(id,is_active) values ('11','YES');
Trigger-
Delimiter $$
create trigger after_device_session_update
after update on device_session1
For Each Row
BEGIN
IF (NEW.is_active="NO") THEN
SET #session_id = new.id;
call new_procedure1(#session_id);
END IF;
END;
Delimiter;
Stored Procedure-
CREATE PROCEDURE `new_procedure1`(IN id VARCHAR(50))
BEGIN
select concat('id : ',id);
END

Drop procedure if exists in mysql

Hi i am trying to create a mysql script that I can run whenever I need to update my database. The script creates a table and then executes some stored procedures.
DELIMITER $$
CREATE TABLE IF NOT EXISTS tbl_name (
col1 bigint(20) NOT NULL AUTO_INCREMENT,
col2 varchar(255) NOT NULL,
col3 varchar(64) NOT NULL,
col4 datetime DEFAULT NULL,
PRIMARY KEY (`col1 `),
UNIQUE KEY col2 (`col2`)
) ENGINE=InnoDB AUTO_INCREMENT=572 DEFAULT CHARSET=utf8$$
CREATE DEFINER=`root`#`localhost` PROCEDURE `myproc`(IN username
VARCHAR(255))
BEGIN
DECLARE var1 VARCHAR(64);
DECLARE expirationDate DATETIME;
SET var1 = 12345;
SET expirationDate = DATE_ADD(NOW(), INTERVAL 30 SECOND);
REPLACE INTO tbl_name (col2, col3, col4) VALUES (someval, var1, expirationDate);
END$$
DELIMITER ;
When I ran the script first time, it created the table and executed the stored procedure in MySQL Workbench. When I ran the same thing second time, I got the error 1304 procedure already exists.
I looked online here about dropping the procedure and then create again. But when I entered the below command before creating the procedure, i got an error on CREATE command with code 1064.
DROP PROCEDURE IF EXISTS myproc;
CREATE DEFINER=`root`#`localhost` PROCEDURE `myproc`(IN username
VARCHAR(255))
.
.
.
I am very new to mysql and not sure how to execute the procedure if it already exists.
Any help would be appreciated.
Since you changed to DELIMITER $$ you need to use that delimiter at the end of each statement until you change it back.
DROP PROCEDURE and CREATE PROCEDURE are separate statements, and each requires its own statement delimiter.
DROP PROCEDURE IF EXISTS myproc $$
Note the delimiter at the end of the line above.
CREATE DEFINER=`root`#`localhost` PROCEDURE `myproc`(IN username
VARCHAR(255))
.
.
.
END $$
And another delimiter at the end of the whole CREATE PROCEDURE statement.

MySQL stored procedure character encoding

I've been experiencing a rather annoying issue, when inserting data into a MySQL database table, using a stored procedure. The database, made in MySQL Workbench 6.3, has characters in tables defined as utf8, and it works perfectly well, but insertion into the tables by stored procedures, changes the character encoding, leaving wrong characters instead of the correct ones. I've been looking all over for an answer. Hope someone can help. Thanks !
delimiter $$
use lfms_browser$$
drop procedure if exists spAddMember$$
create procedure spAddMember
(
in member varchar(60) character set utf8,
in city varchar(60) character set utf8
)
begin
insert into Members
(
member,
city
)
values
(
member,
city
)
;
end$$
delimiter ;

MariaDB stored proc - Getting an error 'Missing SELECT' on INSERT statement

While I created loads of procs in SQL server, I want to start using MariaDB and so tried creating the simple proc below in MySQL Workbench.
I keep on getting an error stating that there is a missing SELECT on the opening '(' after the table name:
DELIMITER $$
drop procedure if exists usp_AddSentEmail$$
CREATE PROCEDURE usp_AddSentEmail (in pSender varchar(36)
,in pTo varchar(1000)
,in pSubject varchar(100)
,in pBody varchar(10000)
,in pRecordDT datetime)
BEGIN
INSERT INTO Emails('To','Subject','Body','Sender','RecordDT','Sent','SentDT')
VALUES (pTo,pSubject,pBody,pSender,pRecordDT,1,pRecordDT);
END$$
DELIMITER ;
Maybe I am trying the wrong google search but that all comes up is delimiter errors.
remove the quotes from the column names in your insert query:
INSERT INTO Emails(To,Subject,Body,Sender,RecordDT,Sent,SentDT)
VALUES (pTo,pSubject,pBody,pSender,pRecordDT,1,pRecordDT);

calling stored procedure inserts NULLs into all columns MySQL

I've created a stored procedure in MySQL to help debug something, however when i call the stored procedure it inserts NULL values into my table for all columns
Table
CREATE TABLE `EncryptionDebug` (
`ObservedValue` mediumtext COLLATE utf8_unicode_ci,
`PublicKey` mediumtext COLLATE utf8_unicode_ci
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
Stored procedure
DELIMITER //
CREATE PROCEDURE `EncryptionDebug`(IN `ObservedValue` MEDIUMTEXT, IN `PublicKey` MEDIUMTEXT)
MODIFIES SQL DATA
BEGIN
DECLARE `ObservedValue` MEDIUMTEXT;
DECLARE `PublicKey` MEDIUMTEXT;
INSERT INTO `EncryptionDebug` (`ObservedValue`,`PublicKey`) VALUES (ObservedValue,PublicKey);
END//
DELIMITER ;
Calling the procedure like so
CALL EncryptionDebug('test','test');
Returns NULL for both columns when i SELECT * FROM EncryptionDebug
Thanks
From the documentation:
13.6.4.2 Local Variable Scope and Resolution
...
A local variable should not have the same name as a table column.
...
One option to try:
DELIMITER //
CREATE PROCEDURE `EncryptionDebug1`(
`ObservedValue` MEDIUMTEXT,
`PublicKey` MEDIUMTEXT
)
MODIFIES SQL DATA
BEGIN
/*
DECLARE `ObservedValue` MEDIUMTEXT;
DECLARE `PublicKey` MEDIUMTEXT;
*/
INSERT INTO `EncryptionDebug` (`ObservedValue`, `PublicKey`)
VALUES
(`ObservedValue`, `PublicKey`);
END//
DELIMITER ;
