Question

你能否告诉我为什么下面的sql有问题。

如果我运行这部分：

Select SmsSCh_ID AS "@Name", CONVERT(CHAR(10), SmsSCh_Scheduledate, 101) 
    + ' ' + LTRIM(RIGHT(CONVERT(CHAR(20), SmsSCh_Scheduledate, 20), 10)) AS "@Time" from Prj_SmsSch
for XML path ('Task'), ROOT('appSchedule')

我得到了正确的结果，但当我把它放在代码中，所以我可以将xml导出到文件中，我得到错误。

这是我的完整代码：

DECLARE 
  @FileName VARCHAR(50),
  @SQLCmd   VARCHAR(500)


select
  @FileName = 'C:\iman\SampleXMLOutput1.xml'

--in this command, we are making sure there is only one ROOT node

SELECT  @SQLCmd = 'bcp ' 
                + '"Select SmsSCh_ID AS "@Name", CONVERT(CHAR(10), SmsSCh_Scheduledate, 101) 
    + ' ' + LTRIM(RIGHT(CONVERT(CHAR(20), SmsSCh_Scheduledate, 20), 10)) AS "@Time" from Prj_SmsSch'
    + ' for XML path ('Task'), ROOT('appSchedule')'"' 
                + ' queryout '  
                + @FileName 
                + ' -w -T -S' + @@SERVERNAME

-- display command, for visual  check
SELECT @SQLCmd AS 'Command to execute'
-- create the XML file
EXECUTE master..xp_cmdshell @SQLCmd

我认为可能的问题是＆＃39;在@SQLCmd里面。错误：

Msg 102, Level 15, State 1, Line 13
Incorrect syntax near ' + LTRIM(RIGHT(CONVERT(CHAR(20), SmsSCh_Scheduledate, 20), 10)) AS "@Time" from Prj_SmsSch'.
Msg 103, Level 15, State 4, Line 14
The identifier that starts with '' 
                + ' queryout '  
                + @FileName 
                + ' -w -T -S' + @@SERVERNAME
              ' is too long. Maximum length is 128.
Msg 105, Level 15, State 1, Line 14
Unclosed quotation mark after the character string '' 
                + ' queryout '  
                + @FileName 
                + ' -w -T -S' + @@SERVERNAME
               '.

感谢您的帮助

试试这个：

你搞砸了内心的引语。它们必须加倍，因为它们在字符串中。此外，我将AS "@name"替换为AS [@name]，因为括号不需要转义。在你的ROOT声明之后，有一个引用很多......无法测试它，希望这有效：

DECLARE 
  @FileName VARCHAR(50),
  @SQLCmd   VARCHAR(500)


select
  @FileName = 'C:\iman\SampleXMLOutput1.xml'

--in this command, we are making sure there is only one ROOT node

SELECT  @SQLCmd = 'bcp ' 
                + '"Select SmsSCh_ID AS [@Name] ' 
                +          ',CONVERT(CHAR(10), SmsSCh_Scheduledate, 101) ' 
                +            ' + '' '' + LTRIM(RIGHT(CONVERT(CHAR(20), SmsSCh_Scheduledate, 20), 10)) AS [@Time] ' 
                +   'from Prj_SmsSch for XML path (''Task''), ROOT(''appSchedule'')"' 
                + ' queryout '  
                + @FileName 
                + ' -w -T -S ' + @@SERVERNAME

-- display command, for visual  check
SELECT @SQLCmd AS 'Command to execute'
-- create the XML file
EXECUTE master..xp_cmdshell @SQLCmd

导出到XML
