mysqli信号到php错误,php,mysql,mysqli,signals,Php,Mysql,Mysqli,Signals,我有一个Mysql存储过程，在某些情况下会出现如下信号错误： CREATE DEFINER=`root`@`localhost` PROCEDURE `InsertAction`(IN `EmployerID` INT, IN `StoreFromID` INT, IN `StoreToID` INT, IN `StoreID` INT, IN `ProductID` INT, IN `Quantity` DECIMAL(10,2), IN `DualOperation` TINYINT

当我通过Mysql查询运行这段代码时，一切似乎都很正常。如果MYSQLI没有抛出异常，那么它会发出“材料不足”的信号，您必须采用老式的方法

$result = $mysqli->query("CALL InsertAction(6, 1, 2, 0, 13, 431243241, 1, 0)");
if ($result === false) {
    echo $mysqli->error;
    exit;
}

此外，第6个参数是十进制（10,2）而不是整数。您传递的数字与10,2不符，如果我记得10,2的正确含义是小数点前8位，小数点后2位，因此请尝试符合以下条件的数字：

 $result = $mysqli->query("CALL InsertAction(6, 1, 2, 0, 13, 4312432.41, 1, 0)");

MYSQLI不会抛出异常，您必须以老式的方式执行

$result = $mysqli->query("CALL InsertAction(6, 1, 2, 0, 13, 431243241, 1, 0)");
if ($result === false) {
    echo $mysqli->error;
    exit;
}

 $result = $mysqli->query("CALL InsertAction(6, 1, 2, 0, 13, 4312432.41, 1, 0)");

上面代码中真正的问题是没有声明变量。所以我将这个Select语句更改为Declare语句

BEGIN
DECLARE lastActionID INT unsigned;
DECLARE lastTransferID INT unsigned;
DECLARE retval INT unsigned;
    START TRANSACTION;
        SELECT SUM(ad.Quantity) INTO retVal FROM productin pri JOIN actiondetails ad ON ad.ID=pri.ID;
        IF DualOperation = 1
            THEN
                IF retVal>Quantity
                    THEN
                        INSERT INTO Actions (EmployerID, StorehouseID, `Date`)
                            VALUES (EmployerID, StoreFromID, CURDATE());
                        SET lastActionID = (SELECT ID FROM Actions ORDER BY ID DESC LIMIT 1);
                        INSERT INTO ProductTransfer (ID, TransferType)
                            VALUES (lastActionID, 0);

                        INSERT INTO ActionDetails (ID, ProductID, Quantity)
                            VALUES (lastActionID, ProductID, Quantity);

                        SET lastTransferID = (SELECT ID FROM ProductTransfer ORDER BY ID DESC LIMIT 1);

                        SET lastActionID = (SELECT ID FROM Actions ORDER BY ID DESC LIMIT 1);
                        INSERT INTO ProductTransfer (ID, TransferType, ParentID) VALUES (lastActionID, 1, lastTransferID);

                        INSERT INTO ActionDetails (ID,ProductID, Quantity)
                            VALUES (lastActionID, ProductID, Quantity);

                INSERT INTO ActionDetails (ID, ProductID, Quantity)
                    VALUES (lastActionID, ProductID, Quantity);
                IF InOrOut = 0
                    THEN
                        INSERT INTO ProductIn (ID, OrganizationID) values (lastActionID, NULL);
                    ELSE
                        IF retVal>Quantity

实际上，您需要做一些准备，以便在PHP中捕获MySql的异常

使用：

实际上，您需要做一些准备来捕获PHP中MySql的异常

使用：

尝试将INT参数作为INT而不是字符串传递，即删除数字周围的单引号，使其成为文本字段。无论是谁编写的，这都具有这两种情况的信号状态。PHP可以像处理任何try/catch异常一样处理它。可能重复@RiggsFolly，谢谢您的评论。当然这些数字应该作为数字传递，我的错。“但这并不能解决问题。”德鲁，谢谢你的评论，但这是另一个话题。PHP也不能用try-catch处理它。正如我所提到的，它没有给出任何异常…尝试将INT参数作为INT而不是字符串传递，即删除数字周围的单引号，然后生成文本字段。无论是谁编写的，这都具有这两种情况的信号状态。PHP可以像处理任何try/catch异常一样处理它。可能重复@RiggsFolly，谢谢您的评论。当然这些数字应该作为数字传递，我的错。“但这并不能解决问题。”德鲁，谢谢你的评论，但这是另一个话题。PHP也不能用try-catch处理它。正如我提到的，它没有给任何例外。。。
