Question

当我更新表记录并且该查询在PHP循环中运行时，我得到表锁定问题并且查询没有响应。

这是我的cstcustomers平板电脑：

 CREATE TABLE `tblcstcustomers` (                              
                       `CustomerId` INT(10) NOT NULL AUTO_INCREMENT,

这里是我的supsuppliers表：

                   CREATE TABLE `tblsupsuppliers` (

                   `Satisfication` FLOAT DEFAULT NULL,                         
                   `RedSurvey` INT(10) DEFAULT NULL,

                   `AmberSurvey` INT(10) DEFAULT NULL,

                   `EventCount` INT(10) DEFAULT '0',                           
                   `IsDeleted` ENUM('Yes','No') DEFAULT 'No',                  
                   `SupplierBrand` VARCHAR(255) DEFAULT NULL,                  
                   PRIMARY KEY (`SupplierId`),                                 
                   KEY `ClientId` (`ClientId`),

                   KEY `FranchiseId` (`FranchiseId`)                           
                 ) ENGINE=MYISAM AUTO_INCREMENT=307490 DEFAULT CHARSET=latin1;

以下查询在循环中运行：

update tblsupsuppliers sup, tblcstcustomers cus
set cus.ExcludeFromReports = 'No', sup.ExcludeFromSummary  = 'No',
sup.ExcludeFromCustomReport = 'No' 
where cus.ClientId = '71' and sup.ClientId ='71';

Answer 1

您无法同时使用transaction更新两个表，以确保以原子方式处理两个UPDATE语句。

BEGIN TRANSACTION

UPDATE Table1 WITH SQL


UPDATE Table2 WITH SQL


COMMIT

更新查询在php循环中触发时被锁定
