导出值形成几乎 2 个具有以下条件的双表

Question

我想为自己做一个项目，但我不知道如何从几乎 2 个双胞胎 tables 导出值，如果库存总数量 =<5，则导出 ID，名称，数量加急table我查询的是这个

CREATE TABLE IF NOT EXISTS `Spital`.`Stoc General` 
(
    `ID Produs` INT,
    `Denumire` VARCHAR(45) NOT NULL,
    `Cantitate` INT NULL,
    PRIMARY KEY (`ID Produs`)
)
ENGINE = InnoDB;

SELECT * FROM `Spital`.`Stoc General`;

INSERT INTO `spital`.`stoc general` (`ID Produs`, `Denumire`, `Cantitate`) 
VALUES ('1', 'Clabax', '20');
INSERT INTO `spital`.`stoc general` (`ID Produs`, `Denumire`, `Cantitate`) 
VALUES ('2', 'Betadina', '15');
INSERT INTO `spital`.`stoc general` (`ID Produs`, `Denumire`, `Cantitate`) 
VALUES ('3', 'Paracetamo', '4');
INSERT INTO `spital`.`stoc general` (`ID Produs`, `Denumire`, `Cantitate`) 
VALUES ('4', 'Oxigen', '3');


CREATE TABLE IF NOT EXISTS `Spital`.`Stoc URGENT` 
(
    `ID Produs` INT NOT NULL AUTO_INCREMENT,
    `Denumire` VARCHAR(45) NOT NULL,
    `Cantitate` INT NOT NULL,
    `Date Delivery` DATETIME NULL,
    PRIMARY KEY (`ID Produs`)
)
ENGINE = MEMORY;

使用 INSERT INTO 语句 使您能够将数据插入指定的列

INSERT INTO `spital`.`stoc urgent`
            (`id produs`,
             `denumire`,
             `cantitate`)
SELECT `id produs`,
       `denumire`,
       `cantitate`
FROM   `spital`.`stoc general` 
where  `cantitate`<5
