我在将变量放入现有代码片段时遇到问题。我确信它很简单，我很遗憾，但我没有到达任何地方。
这是当前代码，没有错误：
new SqlCommand(@"xp_cmdshell 'bcp ""SELECT tipReportingSummaryView.payGroupCode, employee.employeeFName + '' '' + employee.employeeLName AS employeeName, tipReportingSummaryView.employeeID, SUM(tipReportingSummaryView.netChargeTips) AS netChargeTips, tipReportingSummaryView.positionCode, rvc.rvcName, ''CHG TIPS'' AS tipType FROM tipReportingSummaryView INNER JOIN employee ON tipReportingSummaryView.employeeID = employee.employeeID INNER JOIN rvc ON tipReportingSummaryView.rvcID = rvc.rvcID WHERE (tipReportingSummaryView.businessDate >= (dateadd(day,(-15),datediff(day,(0),getdate())))) AND (tipReportingSummaryView.businessDate <= (dateadd)) AND (tipReportingSummaryView.payGroupCode = 1) GROUP BY tipReportingSummaryView.payGroupCode, employee.employeeFName + employee.employeeLName, tipReportingSummaryView.employeeID, tipReportingSummaryView.positionCode, rvc.rvcName, employee.employeeFName + '' '' + employee.employeeLName HAVING SUM(tipReportingSummaryView.netChargeTips) <> 0"" queryout " + filePath + " -U sa -P password -c -t ,'", conn))
我想（tipReportingSummaryView.payGroupCode =）等于payGroup变量的值，所以像这样：
new SqlCommand(@"xp_cmdshell 'bcp ""SELECT tipReportingSummaryView.payGroupCode, employee.employeeFName + '' '' + employee.employeeLName AS employeeName, tipReportingSummaryView.employeeID, SUM(tipReportingSummaryView.netChargeTips) AS netChargeTips, tipReportingSummaryView.positionCode, rvc.rvcName, ''CHG TIPS'' AS tipType FROM tipReportingSummaryView INNER JOIN employee ON tipReportingSummaryView.employeeID = employee.employeeID INNER JOIN rvc ON tipReportingSummaryView.rvcID = rvc.rvcID WHERE (tipReportingSummaryView.businessDate >= (dateadd(day,(-15),datediff(day,(0),getdate())))) AND (tipReportingSummaryView.businessDate <= (dateadd)) AND (tipReportingSummaryView.payGroupCode = " + payGroup + ") GROUP BY tipReportingSummaryView.payGroupCode, employee.employeeFName + employee.employeeLName, tipReportingSummaryView.employeeID, tipReportingSummaryView.positionCode, rvc.rvcName, employee.employeeFName + '' '' + employee.employeeLName HAVING SUM(tipReportingSummaryView.netChargeTips) <> 0"" queryout " + filePath + " -U sa -P password -c -t ,'", conn))
摘要版
电流：
(tipReportingSummaryView.payGroupCode =1)
所需：
(tipReportingSummaryView.payGroupCode = " + payGroup + ")
通过添加“+ payGroup +”，我在该行上获得了各种语法错误，因此显然会导致它被炸毁。
欢迎任何建议。

你需要在第二个字符串文字之前放置另一个@ - 否则双引号将无法编译（它会认为它是两个文字背靠背） - 如下所示。
隔离：" + payGroup + @"
new SqlCommand(@"xp_cmdshell 'bcp ""SELECT tipReportingSummaryView.payGroupCode, employee.employeeFName + '' '' + employee.employeeLName AS employeeName, tipReportingSummaryView.employeeID, SUM(tipReportingSummaryView.netChargeTips) AS netChargeTips, tipReportingSummaryView.positionCode, rvc.rvcName, ''CHG TIPS'' AS tipType FROM tipReportingSummaryView INNER JOIN employee ON tipReportingSummaryView.employeeID = employee.employeeID INNER JOIN rvc ON tipReportingSummaryView.rvcID = rvc.rvcID WHERE (tipReportingSummaryView.businessDate >= (dateadd(day,(-15),datediff(day,(0),getdate())))) AND (tipReportingSummaryView.businessDate <= (dateadd)) AND (tipReportingSummaryView.payGroupCode = " + payGroup + @") GROUP BY tipReportingSummaryView.payGroupCode, employee.employeeFName + employee.employeeLName, tipReportingSummaryView.employeeID, tipReportingSummaryView.positionCode, rvc.rvcName, employee.employeeFName + '' '' + employee.employeeLName HAVING SUM(tipReportingSummaryView.netChargeTips) <> 0"" queryout " + filePath + @" -U sa -P password -c -t ,'", conn))
你应该在filePath连接之后放一个。
