我无法将变量处理到现有代码片段中。我敢肯定，我缺少一些简单的东西，但是我什么也没有。

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))

我希望 (tipReportingSummaryView.payGroupCode = ) 等于 payGroup 变量的值，所以是这样的：

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

当前的：

(tipReportingSummaryView.payGroupCode =1)

期望：

(tipReportingSummaryView.payGroupCode = " + payGroup + ")

通过添加“+ payGroup +”，我在该行上得到了各种语法错误，所以它显然导致它被炸毁。

欢迎任何建议。

您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（它会认为这是背靠背的两个文字） - 如下所示。

孤立：" + 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))

您可能也应该在 filePath 连接之后放置一个。
