Question

我使用这个sql语句来产生所需的结果。并希望通过数据集（.xsd）使用rdlc在C＃中的报表中显示这些结果查询。

SELECT pay.Cutoff, 
       emp.Id, 
       emp.LastName, 
       emp.FirstName, 
       emp.MiddleName, 
       emp.TinNumber, 
       job.Rate * 25 AS FixBIR,

       (SELECT COUNT(*) AS MonthsWorked 
       FROM payroll AS pay3
       WHERE YEAR(pay3.DateGenerated) = 2014
             AND pay3.EmployeeId = 1 
             AND pay3.Cutoff = 1
       ORDER BY MONTH(pay3.DateGenerated) ASC) * (job.Rate * 25)  
       AS MonthsWorked_FixBIR_TODATE,

       pay.TaxWithheld,

       (SELECT SUM(payroll2.TaxWithheld) AS TaxTotal
       FROM employee AS employee2 
       INNER JOIN payroll AS payroll2 
       ON employee2.Id = payroll2.EmployeeId
       WHERE (payroll2.Cutoff = 1) 
       AND (employee2.Id = emp.Id) 
       AND YEAR(payroll2.DateGenerated) = 2014) 
       AS Tax_TODATE,

       YEAR(pay.DateGenerated) AS YEAR

FROM employee AS emp 
INNER JOIN payroll AS pay 
ON emp.Id = pay.EmployeeId
INNER JOIN job 
ON emp.JobId = job.Id
WHERE pay.Cutoff = 1 
AND pay.PayrollMonth = 'August' 
AND Year(pay.DateGenerated) = 2014

此声明正常（在navicat中测试）。

然而，当我使用查询生成器将其转移到数据集时，它不起作用。错误说：

在配置TableAdapter时，向导会检测到以下问题：＆＃34;填充＆＃34;详细说明：

！生成的SELECT语句 SELECT子句出错：表达式附近＆＃39; SELECT＆＃39; SELECT子句出错：表达式附近＆＃39; FROM＆＃39; 缺少条款 SELECT子句出错：表达式附近＆＃39;，＆＃39;。无法解析查询文本

如果我尝试在SELECT语句中使用简单的子查询，则会出现错误：

无法在图表和标准窗格中以图形方式表示查询。

如何在rdlc中使用sql语句？除了数据集中的查询构建器之外还有其他方法吗？

在数据集C＃中使用查询生成器执行子查询
