Question

使用MS SQL Server，我有以下代码-它是通过EXECUTE sp_executesql命令执行的：

Declare @Cmd nvarchar(max)
;with DistinctTables as
(
select distinct [DestTable], [SourceFile] from [tbl_IN_Ctrl_Dtl]
),
InsertCommands as
(
-- columns from Destination table
select *,
'BEGIN TRY insert into ' + [DestTable] + '(' +
STUFF((
        SELECT ',' + [DestCol]
        FROM [tbl_IN_Ctrl_Dtl] t1
        where t1.DestTable = drt.DestTable
        GROUP BY DestCol,ORDINAL_POSITION
        ORDER BY ORDINAL_POSITION 
        FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)'),1,1,'')
+ ')' + 
' select ' + 
-- columns from source table
STUFF((
        SELECT ',' + [SourceCol]
        FROM [tbl_IN_Ctrl_Dtl] t1
        where t1.DestTable = drt.DestTable
        GROUP BY SourceCol,ORDINAL_POSITION
        ORDER BY ORDINAL_POSITION
        FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)'),1,1,'')
        + ' from ' + [SourceFile] 
        + '; 
        update tbl_IN_Ctrl_Header set ErrMsg = @@ERROR where SourceFile_INSERT = 0 and SourceFile = ''' + [SourceFile]+ '''' 
        +';
        update tbl_IN_Ctrl_Header set SourceFile_INSERT = 1 where SourceFile_INSERT = 0 and SourceFile = ''' + [SourceFile]+ '''' 
        +'; END TRY BEGIN CATCH'
        as InsertCommand
 from DistinctTables drt 
)
select @cmd = 
STUFF((
        SELECT ';' + char(10) + [InsertCommand]
        FROM InsertCommands
        FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)'),1,1,'')
+';' from InsertCommands ic

--print @cmd

EXECUTE sp_executesql @cmd

我可以使用以下行检索错误号：

update tbl_IN_Ctrl_Header set ErrMsg = @@ERROR where SourceFile_INSERT = 0 and SourceFile = ''' + [SourceFile]+ ''''

但是，如何检索实际的文本错误消息？如果我使用ERROR_MESSAGE我只会得到Null。如何修改以上内容以将“ ErrMsg”更新为实际的文本错误消息？我在插入的开始处放了一个BEGIN TRY，在更新的末尾放了END TRY，但是现在我在';'附近收到错误语法错误。

如何使用EXECUTE sp_executesql插入Error_Message
