我正在使用EntityFramework.Extended库进行一组批量更新。我正在更新的表的重要部分如下所示:
CREATE TABLE [dbo].[BoosterTargetLog]
(
[Id] BIGINT NOT NULL identity PRIMARY KEY,
[CustomerUserId] INT NULL,
CookieId uniqueidentifier not null,
CONSTRAINT [FK_BoosterTargetLog_ToOrganizationCookie] FOREIGN KEY (CookieId) REFERENCES [OrganizationCookie]([CookieId])
)
C#更新代码如下所示:
var query = db.BoosterTargetLogs
.Where(x =>
x.OrganizationCookie.OrganizationId == organizationId &&
x.CookieId == cookieId &&
x.CustomerUserId == null);
var updated = await query.UpdateAsync(x => new BoosterTargetLog
{
CustomerUserId = customerUserId
});
生成如下所示的SQL更新代码:
exec sp_executesql N'UPDATE [dbo].[BoosterTargetLog] SET
[CustomerUserId] = @p__update__0
FROM [dbo].[BoosterTargetLog] AS j0 INNER JOIN (
SELECT
[Extent2].[OrganizationId] AS [OrganizationId],
CAST( [Extent1].[Id] AS int) AS [C1]
FROM [dbo].[BoosterTargetLog] AS [Extent1]
INNER JOIN [dbo].[OrganizationCookie] AS [Extent2] ON [Extent1].[CookieId] = [Extent2].[CookieId]
WHERE ([Extent2].[OrganizationId] = @p__linq__0) AND ([Extent1].[CookieId] = @p__linq__1) AND ([Extent1].[CustomerUserId] IS NULL)
) AS j1 ON (j0.[Id] = j1.[Id])',N'@p__linq__0 int,@p__linq__1 uniqueidentifier,@p__update__0 int',@p__linq__0=1075,@p__linq__1='44A191F0-9086-4867-9777-ACEB9BB3B944',@p__update__0=95941
当我通过C#代码运行更新时,或者如果我手动执行生成的SQL,我收到此错误:
Invalid column name 'Id'.
问题是生成的SQL中存在错误。请注意这样的内容:
AS j1 ON (j0.[Id] = j1.[Id])
实际上应该是:
AS j1 ON (j0.[Id] = j1.[C1])
我的假设是,EntityFramework.Extended库中存在某种错误。
建议解决方法?
答案 0 :(得分:1)
当我的Where
子句与任何项目都不匹配时,我收到了同样的错误,但仅。
请检查以确保您的数据符合:
var query = db.BoosterTargetLogs
.Where(x =>
x.OrganizationCookie.OrganizationId == organizationId &&
x.CookieId == cookieId &&
x.CustomerUserId == null);
我进行检查以确保我有一些记录要更新,也许试试这个:
if (query.Any())
{
var updated = await query.UpdateAsync(x => new BoosterTargetLog
{
CustomerUserId = customerUserId
});
}
我没有使用UpdateAsync
,只是简单Update
。希望这同样适用于您的情况。
