SQL Query在Management Studio中运行良好，但不会在BCP下运行

Question

此查询在Management Studio中运行正常，但在尝试使用批量复制实用程序时遇到一些错误。

这是我得到的......

C:\>BCP     "SELECT title1, [precinct percent] AS [PrecinctPercent], leader, [leader
     percent] AS [LeaderPercent], Winner, WinningVotes, leader2, [leader2 percent] A
    S [LeaderPercent2], Loser, LosingVotes FROM dbo.[RACE] r inner join (select rc.[
    race number], max(case when seqnum = 1 then [candidate num] end) as Winner, max(
    case when seqnum = 1 then Votes end) as WinningVotes, max(case when seqnum = 2 t
    hen [candidate num] end) as Loser, max(case when seqnum = 2 then Votes end) as L
    ossingVotes (select rc.*, row_number() over (partition by rc.[race.number] order
     by votes desc) as seqnum from dbo.[RACE CANDIDATES] rc ) rc group by rc.[race n
     umber] ) rc on r.[race number] = rc.[race.number] FOR XML PATH ('WQAD'), ROOT('r
    oot')" QUERYOUT "C:\Users\andersse\RESULTS222.XML" -c -t -T -S WQAD-ENG7\SQLEXPR
    ESS
    "SQLState = 37000, NativeError = 102
    Error = [Microsoft][SQL Server Native Client 10.0][SQL Server]Incorrect syntax n
    ear '('.
    SQLState = 37000, NativeError = 102
    Error = [Microsoft][SQL Server Native Client 10.0][SQL Server]Incorrect syntax n
    ear 'rc'.
    SQLState = 37000, NativeError = 8180
    Error = [Microsoft][SQL Server Native Client 10.0][SQL Server]Statement(s) could
    not be prepared."

有没有人知道为什么（）作为查询和BCP没有被正确读取？

感谢您阅读本文。

您需要确保BCP与SSMS具有相同的数据库上下文。对于大多数查询，您只需说：

即可

FROM [databasename].dbo.[RACE]
...
FROM [databasename].dbo.[RACE CANDIDATES]

您可能还需要通过传递-d参数来确保正确的数据库上下文（正如您在FOR XML中使用sqlcmd所需要的那样，正如您在{{3}中发现的那样虽然我无法使用2012工具重现这一点，例如

BCP "your query with db prefixes" QUERYOUT "file" -c -t -Sserver -T -dDatabase

（见this answer。）

您还需要确保使用正确的BCP副本;直到2012年才添加-d参数，因此您可能需要将客户端工具更新到最新版本。以下是2008年和2012年版BCP之间的差异;请注意-d不可用：

请注意，对我来说，旧版本是默认调用的版本，因为我的环境路径是根据我安装的SQL Server的第一个版本设置的，而不是最后一个版本。因此，请确保您明确使用最新版本。
