Question

我有如下的sql语句：

Declare @Inserted_FileID as int        

insert into EH_PP_TeacherEvalArtifacts (EH_PP_TEA_OriginalUploadDateTime,EH_PP_TEA_LastModidiedDateTime,EH_PP_TEA_FileVersionNum,EH_PP_TEA_FileName,EH_PP_TEA_FileDesc,EH_PP_TE_TeacherEvalID,EH_PP_TEA_UploadedBy)        
    OUTPUT INSERTED.EH_PP_TEA_FileID  into @Inserted_FileID
    values(getdate(),getdate(),@EH_PP_TEA_FileVersionNum,@EH_PP_TEA_FileName,@EH_PP_TEA_FileDesc,@EH_PP_TE_TeacherEvalID,@EH_PP_TEA_UploadedByAccountID)

on：

OUTPUT INSERTED.EH_PP_TEA_FileID  into @Inserted_FileID

它向我显示错误：

必须声明表变量@Inserted_FileID

我只想将当前插入的fileid存储到@Inserted_FileID整数变量中。

我该怎么做？

Answer 1

如果@Inserted_FileID是标识列，则使用

**SET Inserted_FileID = @@identity**

如果没有，请使用以下：

Declare @Inserted_FileID as int
DECLARE @TempTable TABLE (RowID int not null primary key identity(1,1),FILE_ID VARCHAR(4))

insert into EH_PP_TeacherEvalArtifacts 
(EH_PP_TEA_OriginalUploadDateTime,
 EH_PP_TEA_LastModidiedDateTime,
 EH_PP_TEA_FileVersionNum,
 EH_PP_TEA_FileName,
 EH_PP_TEA_FileDesc,
 EH_PP_TE_TeacherEvalID,
 EH_PP_TEA_UploadedBy) 
values
(getdate(),
 getdate(),
 @EH_PP_TEA_FileVersionNum,
 @EH_PP_TEA_FileName,
 @EH_PP_TEA_FileDesc,
 @EH_PP_TE_TeacherEvalID,
 @EH_PP_TEA_UploadedByAccountID)   

INSERT INTO @TempTable 
Select top 1  EH_PP_TEA_FileID 
from EH_PP_TeacherEvalArtifacts 
order by EH_PP_TEA_LastModidiedDateTime DESC

Select @Inserted_FileID = FILE_ID  from @TempTable

输出inserted.id给出错误必须声明表类型
