我有一个复杂的CLR函数,它返回一行。我可以使用Cross Apply来选择工作正常但Update或Insert失败的结果。选择始终有效但插入,选择和更新失败并出现以下错误,此错误不会出现在选择查询中。
Msg 6522, Level 16, State 1, Line 1
A .NET Framework error occurred during execution of user-defined routine or aggregate "AppendCLR":
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
System.ArgumentOutOfRangeException:
at System.Collections.ArrayList.get_Item(Int32 index)
at AppendCLR.ProcessData(String EnrollmentID,String InstituteCode)
at AppendCLR.UserDefinedFunctions(SqlString EnrollmentID,SqlString InstituteCode)
.
The statement has been terminated.
TestCLR
是我需要使用CLR函数AppendCLR
的结果更新的表。 #TestCLR_TEMP
和@TestCLR_TEMP
分别是临时变量和表变量。
这不起作用:
update a set
a.ID=b.ID,
a.Branch=b.Branch,
a.CourseID=b.CourseID,
a.EnrolDate=b.EnrolDate,
a.CourseTag=b.CourseTag,
a.Micro=b.Micro,
a.StudentTag=b.StudentTag FROM TestCLR a cross apply
dbo.AppendCLR([EnrollmentID],[InstituteCode]) b
这也不起作用:
select * into #TestCLR_TEMP from dbo.AppendCLR([EnrollmentID],[InstituteCode])
OR
select * into TestCLR_TEMP from dbo.AppendCLR([EnrollmentID],[InstituteCode])
然而这有效:
declare table @TestCLR_TEMP (ID bigint,
Branch varchar(100),
CourseID bigint,
EnrolDate DateTime,
CourseTag varchar(100),
Micro varchar(100),
StudentTag varchar(100))
insert into @TestCLR_TEMP select
a.ID,
b.Branch,
b.CourseID,
b.EnrolDate,
b.CourseTag,
b.Micro,
b.StudentTag FROM TestCLR a cross apply
dbo.AppendCLR([EnrollmentID],[InstituteCode]) b
--I have now my results in @TestCLR_TEMP, I can perform an inner join to append these results back to my original table TestCLR
这始终有效:
Select * from dbo.AppendCLR(123,456)
基本上所有插入,更新都会在真实表格上尝试时失败.SSMS中的错误并没有说明重要但我可以根据需要发布。 谢谢!
答案 0 :(得分:0)
我觉得自己很愚蠢,但原始错误为Transaction Context In Use By Another Session
,同时将选择查询的结果读入DataTable
,而我在阅读此空System.ArgumentOutOfRangeException
时获得DataTable
。
修复程序在连接字符串中使用Enlist=false
。
我知道我应该专注于错误报告,但感谢你们的努力。
