first of all my english is not so good but i think maybe enogh. Ok, I have a procedure for inserting.
Procedure is
CREATE PROCEDURE `PhotoUpdate`(IN `uid` INT, IN `foto` VARCHAR(255))
BEGIN
INSERT INTO photos (Dosya, UyeID)
VALUES (foto, uid)
ON DUPLICATE KEY UPDATE UyeID = uid;
END
And Im calling it like this
Call PhotoUpdate(87,'87_54284.jpg');
Photos table is
id Dosya UyeID
1 55_48615.jpg 55
2 87_95165.jpg 87
Im trying to ('uid'->87) if uid equals to photos.UyeID, I mean if UyeID=87 then Update row. If else then insert.
This querys that i tryd. But didnt work.
IF EXISTS (SELECT ID FROM photos WHERE UyeID = uid)
UPDATE photos SET Dosya = foto WHERE UyeID = uid;
ELSE
INSERT INTO photos (Dosya, UyeID) Values(foto, uid);
END IF;
How can i do this guys?
Alternatively:
DELIMITER $$
DROP PROCEDURE IF EXISTS `PhotoUpdate`$$
CREATE PROCEDURE `PhotoUpdate`(`uid` INT UNSIGNED, `foto` VARCHAR(255))
BEGIN
INSERT INTO `photos` (`Dosya`, `UyeID`)
VALUES (`foto`, `uid`)
ON DUPLICATE KEY UPDATE `Dosya` = `foto`;
END$$
DELIMITER ;
SQL Fiddle demo
Try REPLACE INTO photos (Dosya, UyeID) VALUES(foto, uid);
If you create an unique index on UyeID, or even better get rid of the ID column and make UyeID the primary key, you can use INSERT .... ON DUPLICATE KEY UPDATE.
Example
INSERT INTO photos (Dosya, UyeID)
VALUES ('example.jpg', 87)
ON DUPLICATE KEY UPDATE
Dosya = VALUES(Dosya)
If you use VALUES you can use this also with a bulk insert

I have defined the following stored procedure to add/update a table called ImportedProduct.
If the primary key, ImportedProductId is provided and is greater than zero, then update the exiting record otherwise insert a new one:
DELIMITER //
CREATE PROCEDURE AddOrUpdateImportedProduct (
IN ImportedProductId BIGINT,
IN UniqueThirdPartyCode VARCHAR(64),
IN BranchId BIGINT
)
BEGIN
IF ImportedProductId <= 0 THEN
INSERT INTO ImportedProduct(UniqueThirdPartyCode, BranchId)
VALUES(UniqueThirdPartyCode, BranchId);
ELSE
UPDATE
ImportedProduct
SET
UniqueThirdPartyCode = UniqueThirdPartyCode,
BranchId = BranchId
WHERE
ImportedProductId = ImportedProductId;
END IF;
END //
DELIMITER ;
Now I run the following code to update an existing row:
CALL AddOrUpdateImportedProduct (1, 'y-105', 24);
I can see that the record with with ImportedProductId = 1 exists in the table, but I am getting the following error:
You are using safe update mode and you tried to update a table without
a WHERE that uses a KEY column To disable safe mode
I am pretty sure ImportedProductId = ImportedProductId holds always.. Perhaps rename your variable or add an alias to the updated table.
I need to create a procedure for inserting records into 2 tables, but on the second table, I want to insert the last ID that was inserted on the first table. Could anyone help me with this?
This is my query
DELIMITER //
DROP PROCEDURE IF EXISTS ROOM_FEATURE_INSERT;
CREATE PROCEDURE ROOM_FEATURE_INSERT (propID INT, featID INT, featNme VARCHAR(50))
BEGIN
-- BEGIN CHECK
IF NOT EXISTS
(
SELECT rFeatureName FROM COMPANY_T3s71.PROPERTY_RFEATURE PRFE
INNER JOIN COMPANY_T3s71.ROOM_FEATURE RFEA ON PRFE.rFeatureID=RFEA.rFeatureID
WHERE BINARY rFeatureName = featNme AND propertyID = propID
)
AND
(
SELECT rFeatureName FROM COMPANY_T3s71.ROOM_VIEW
WHERE BINARY rFeatureName = featNme
)
THEN
-- IF NOT EXISTS INSERT INTO 1st TABLE
INSERT INTO COMPANY_T3s71.ROOM_FEATURE (rFeatureName) VALUES (featNme);
END IF;
-- END CHECK
-- BEGIN CHECK 2nd TABLE
IF NOT EXISTS
(
SELECT propertyID, rFeatureID FROM COMPANY_T3s71.PROPERTY_RFEATURE
WHERE rFeatureID = featID AND propertyID = propID
)
THEN
-- IF NOT EXISTS INSERT INTO 2nd TABLE
INSERT INTO COMPANY_T3s71.PROPERTY_RFEATURE (propertyID, rFeatureID) VALUES (propID, featID);
END IF;
-- END CHECK 2nd TABLE
END
DELIMITER ;
How do we pass the featID param, when we just inserted it on the first INSERT query?
Thank you before hand.
Use SET featID = LAST_INSERT_ID(); after the first query and then use the variable
INSERT INTO COMPANY_T3s71.ROOM_FEATURE (rFeatureName) VALUES (featNme);
SET featID = LAST_INSERT_ID();
However, if the data is not insert at anytime then you have to make query in the if block to set the value for featID.
Here is the table I created.
USE my_guitar_shop;
DROP TABLE IF EXISTS Products_Audit;
CREATE TABLE Products_Audit (
audit_id INT PRIMARY KEY,
category_id INT REFERENCES categories(category_id),
product_code VARCHAR ( 10 ) NOT NULL UNIQUE ,
product_name VARCHAR ( 255 ) NOT NULL,
list_price INT NOT NULL,
discount_percent INT NOT NULL DEFAULT 0.00 ,
date_updated DATETIME NULL);
Create a trigger named products_after_update. This trigger should insert the old data about the product into the Products_Audit table after the row is updated. Then, test this trigger with an appropriate UPDATE statement.
Here is the trigger I created but the data is not showing up in the Products_Audit table it is showing all null.
USE my_guitar_shop;
DROP TRIGGER IF EXISTS products_after_update;
DELIMITER $$
CREATE TRIGGER products_after_update
BEFORE UPDATE ON products
FOR EACH ROW
BEGIN
INSERT INTO products_audit (audit_id, product_id, category_id, product_code,
product_name, list_price, discount_percent, date_updated)
SELECT audit_id, products.product_id, products.category_id, products.product_code,
products.product_name,products.list_price, products.discount_percent, date_updated
FROM products JOIN products_audit
ON products_audit.audit_id = (SELECT audit_id FROM inserted);
END $$
DELIMITER ;
EDIT with the INSERT INTO
USE my_guitar_shop;
DROP TRIGGER IF EXISTS products_after_update;
DELIMITER $$
CREATE TRIGGER products_after_update
BEFORE UPDATE ON products
FOR EACH ROW
BEGIN
INSERT INTO products_audit (audit_id, product_id, category_id,product_code,
product_name, list_price, discount_percent, date_updated)
VALUES (OLD.audit_id, OLD.product_id, OLD.category_id, OLD.product_code,
OLD.product_name, OLD.list_price, OLD.discount_percent, OLD.date_updated)
DELIMITER ;
You are overcomplicating the insert. As mysql documentation on triggers says:
In an UPDATE trigger, you can use OLD.col_name to refer to the columns
of a row before it is updated and NEW.col_name to refer to the columns
of the row after it is updated.
Therfore, use the OLD.column_name format in the insert. Also, I would set the audit_id field to auto increment and leave it out of the insert:
INSERT INTO products_audit (product_id, category_id, product_code,
product_name, list_price, discount_percent, date_updated)
VALUES (OLD.product_id, OLD.category_id, OLD.product_code,
OLD.product_name, OLD.list_price, OLD.discount_percent, OLD.date_updated)
Here's an example of how I do it:
CREATE OR REPLACE EDITIONABLE TRIGGER E_TABLE_TRG
before insert or update or delete on e_table
for each row
declare
l_seq number;
begin
-- Get a unique sequence value to use as the primary key
select s_seq.nextval
into l_seq
from dual;
if inserting then
:new.date_opened := sysdate;
:new.last_txn_date := null;
:new.status := 'A';
end if;
if inserting then
insert into e_table_history
(
t_seq,
user_id,
date_opened,
last_txn_date,
status,
insert_update_delete,
insert_update_delete_date
)
values
(
l_seq,
:new.user_id,
:new.date_opened,
:new.last_txn_date,
:new.status,
'I',
sysdate
);
elsif updating then
insert into e_table_history
(
t_seq,
date_opened,
last_txn_date,
status,
insert_update_delete,
insert_update_delete_date
)
values
(
l_seq,
:new.date_opened,
:new.last_txn_date,
:new.status,
'U',
sysdate
);
else
insert into e_table_history
(
t_seq,
date_opened,
last_txn_date,
status,
insert_update_delete,
insert_update_delete_date
)
values
(
l_seq,
:old.date_opened,
:old.last_txn_date,
:old.status,
'D',
sysdate
);
end if;
end;
/
ALTER TRIGGER E_TABLE_TRG ENABLE;

I would like to capture the primary key value of column based on the last inserted record. Below is the table structure:
create table test
(
id varchar(100) not null primary key,
rmain varchar(100),
rpart bigint
);
Stored Procedure:
Delimiter $$
DROP PROCEDURE IF EXISTS insTest$$
Create Procedure insTest()
Begin
Set #rmain := (select trim(concat('DNB', DATE_FORMAT(CURRENT_DATE(), '%y'), DATE_FORMAT(CURRENT_DATE(), '%m'))));
IF ((trim(DATE_FORMAT(CURRENT_DATE(),'%m')) = 01) OR (trim(DATE_FORMAT(CURRENT_DATE(),'%m')) = 1)) THEN
Set #rpart = 1;
END IF;
IF ((trim(DATE_FORMAT(CURRENT_DATE(),'%m')) != 01) OR (trim(DATE_FORMAT(CURRENT_DATE(),'%m')) != 1)) THEN
Set #rpart := (select coalesce(max(rpart),0) from test) + 1;
END IF;
insert into Test (ID, rmain, rpart) values (concat(#rmain,#rpart),#rmain,#rpart);
End$$
DELIMITER ;
Please advice. I checked on last_insert_ID() but it works for primary key column with auto_increment setting only. Thanks in advance...
Why? What if you get select max(id) or if you get select id from tbl1 order by id desc limit 1?
See Transaction In MySQL. Also, set the transaction isolation level to READ COMMITTED
declare last_id INT;
START TRANSACTION;
INSERT INTO tbl1(id,col1,col2) values(1001,'test','test');
SELECT last_id = id FROM tbl1 ORDER BY id DESC LIMIT 1
COMMIT;
INSERT INTO test (a,b,c) values (1,2,3);
SELECT LAST_INSERT_ID();
this way you can access the last inserted id
I want to add an after insert trigger which will do the following.
The first IF condition works normally, but when it comes to the second everything stops.
Any ideas?
USE `Syslog`;
DELIMITER $$
CREATE TRIGGER `SystemEventsR_AINS` AFTER INSERT ON SystemEventsR FOR EACH ROW
IF
(exists
(select syslogtag from SystemEventsRcounter where syslogtag=
new.syslogtag)
AND
(select simpledate from SystemEventsRcounter
where syslogtag=new.syslogtag)=new.simpledate)
THEN
UPDATE SystemEventsRcounter
SET records=records+1
WHERE SystemEventsRcounter.syslogtag=new.syslogtag;
ELSE INSERT SystemEventsRcounter (simpledate, syslogtag, records) values (new.simpledate,new.syslogtag,1);
END IF
UPDATED:
What you need is INSERT INTO ... ON DUPLICATE KEY.
CREATE TRIGGER `SystemEventsR_AINS`
AFTER INSERT ON SystemEventsR
FOR EACH ROW
INSERT INTO SystemEventsRcounter (simpledate, syslogtag, records)
VALUES (NEW.simpledate, NEW.syslogtag, 1)
ON DUPLICATE KEY UPDATE records = records + 1;
In order for it to work you need to create a unique composite index on (simpledate, syslogtag)
CREATE UNIQUE INDEX idx_u_simpledate_syslogtag
ON SystemEventsRcounter (simpledate, syslogtag);
Here is SQLFiddle demo.
If you wanted it your way then it might look like
DELIMITER $$
CREATE TRIGGER `SystemEventsR_AINS`
AFTER INSERT ON SystemEventsR
FOR EACH ROW
BEGIN
IF (
SELECT COUNT(*) simpledate
FROM SystemEventsRcounter
WHERE syslogtag = NEW.syslogtag
AND simpledate = NEW.simpledate
) > 0 THEN
UPDATE SystemEventsRcounter
SET records = records + 1
WHERE SystemEventsRcounter.syslogtag = NEW.syslogtag;
ELSE
INSERT INTO SystemEventsRcounter (simpledate, syslogtag, records)
VALUES (NEW.simpledate, NEW.syslogtag, 1);
END IF;
END$$
DELIMITER ;
