Obtenez des valeurs d'une instruction SELECT et insérez-les dans la procédure stockée Table Table

Question

Voici ma procédure stockée.

Je souhaite sélectionner des données à partir d'une table, enregistrez-la dans une variable puis insérez dans une autre variable. Cependant, mon énoncé Select a l'endroit où. La valeur de la journée devrait provenir de la boucle. Cela signifie dans la boucle pour que je recevrai une journée (DateTime) pour un jour particulier. Sur la base de cela, je veux récupérer des valeurs et l'utiliser dans une déclaration d'insertion.

DROP PROCEDURE IF EXISTS home_cleaner.getAvailableDateAndTime; CREATE PROCEDURE home_cleaner.`getAvailableDateAndTime`(dateTime date) BEGIN DECLARE dateTime datetime DEFAULT NOW(); DECLARE dateTimeCounter int DEFAULT 0; DECLARE dateTimeCounterLimit int DEFAULT 90; DECLARE result varchar(255) DEFAULT NULL; DECLARE result1 varchar(255) DEFAULT NULL; DECLARE result2 varchar(255) DEFAULT NULL; DECLARE result3 varchar(255) DEFAULT NULL; DECLARE result4 varchar(255) DEFAULT NULL; DECLARE c CURSOR FOR SELECT GROUP_CONCAT( cleaner_calender.from, "-", cleaner_calender.to) AS result FROM cleaner_calender WHERE day = DAYNAME(dateTime) AND status = "1"; DROP TABLE IF EXISTS foo; CREATE TABLE foo ( id int UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, date1 date NULL, dayNameP varchar(20) NULL, timings varchar(255) NULL ) ENGINE = innodb; OPEN c; WHILE dateTimeCounter < dateTimeCounterLimit DO // here i want to fetch result1 for the dateTime which will be incrementing FETCH c INTO result1; INSERT INTO foo(date1, dayNameP, timings) VALUES (dateTime, DAYNAME(dateTime), result1); SET dateTime = DATE_ADD(dateTime, INTERVAL 1 DAY); SET dateTimeCounter = dateTimeCounter + 1; END WHILE; CLOSE c; SELECT * FROM foo; END;

Le problème était mon select La requête renvoyait plus d'une ligne et mon code ne les manipulait pas via une "boucle" de sorte que cela ne fonctionnait pas et me donnait des erreurs.

Ceci est ma nouvelle procédure ...
