实体框架在MySQL数据库上执行RawSql

标签: mysql sql-server entity-framework

我正在使用EntityFramework连接到MySql服务器。

我有一个在数据库中插入许多对象的方法。为此,我正在生成一个SQL脚本,我使用dbContext.Database.ExecuteSqlCommand(script)方法执行它。

EntityFramework连接到MS SQL Server时,此工作流程正常。

现在,在我将其移动到MySql后,它会在执行脚本时抛出错误。

  

'`'。

附近的语法不正确

重要

已生成脚本以匹配MySql语法。如果我在MySQL Workbench中运行该脚本,则查询会成功执行。

我认为EntityFramework正在尝试解析我发送的脚本,但是使用MS SQL语言。

以下是Stack Trace:

更新

这是生成的MySQL查询

INSERT INTO `appformapp`.`appformdata`(`Id`, `ApplicationIdentifier`, `ApplicationName`, `LastSavedDate`, `LastActivity`)
VALUES (N'59bbf577-d601-4857-aabf-84b69b2d7b75', N'APP-TMH3EI', N'Test ABV', N'2016-10-17 05:56:16', N'2016-10-17 05:56:16');

实体框架已与MySql合作。只有在使用dbContext.Database.ExecuteSqlCommand(script)

时才会触发错误
