Question

我有一些SQL代码我在控制台应用程序中执行。它在扔：

＆＃34; system.Data.SqlClient.SqlException：＆＃39;附近的语法不正确关键字＆＃39; TB＆＃39;。＆＃39;

我尝试多次更改代码以使其正常工作，但它仍然会抛出相同的错误。通过尝试解决它，我已经发现了最后一个＆＃34; TB＆＃34;第二行到最后一行是错误的原因，它表示＆＃34;）TB＆＃34;。有没有人知道为什么它不喜欢那里的结核病？这是代码：

 string SQLCode = "SELECT TB.RowType,TB.company,TB.Account,TB.segvalue1,TB.segvalue2,TB.segvalue3,TB.segvalue4,TB.fiscalyear,TB.fiscalperiod,SUM(TB.BalanceAmt) as tbBalanceAmt" +
                    "FROM(SELECT 'Actual' AS RowType,GLJ.company,GLJ.glaccount AS Account,GLJ.segvalue1,GLJ.segvalue2,GLJ.segvalue3,GLJ.SegValue4," +
                    "GLJ.fiscalyear,GLJ.fiscalperiod,GLJ.jedate,GLJ.description,GLJ.vendornum,GLJ.apinvoicenum,SUM(GLJ.debitamount - GLJ.creditamount) as glBalanceAmt,"+
                    "GLJ.groupid,GLJ.posteddate FROM GLJrnDtl GLJ GROUP BY GLJ.company,GLJ.glaccount,GLJ.segvalue1,GLJ.segvalue2,GLJ.segvalue3,"+
                    "GLJ.SegValue4,GLJ.fiscalyear,GLJ.fiscalperiod,GLJ.jedate,GLJ.description,GLJ.vendornum,GLJ.apinvoicenum,GLJ.groupid,GLJ.posteddate"+ 
                    " UNION ALL SELECT 'Budget' AS RowType,GLB.company,GLB.BalanceAcct AS Account,GLB.segvalue1,GLB.segvalue2,GLB.segvalue3,GLB.segvalue4,GLB.fiscalyear,GLB.fiscalperiod,"+
                "GLB.Date01 AS jedate,'' AS description,'' AS vendornum,'' AS apinvoicenum,SUM(GLB.BudgetAmt) as gbBalanceAmt,'' AS groupid,"+
                    "0 AS posteddate FROM GLBudgetDtl GLB WHERE GLB.segvalue3 <> '' AND GLB.BalanceType = 'D'"+
                "GROUP BY GLB.company,GLB.BalanceAcct,GLB.segvalue1,GLB.segvalue2,GLB.segvalue3,GLB.segvalue4,GLB.fiscalyear,GLB.fiscalperiod,GLB.Date01, GLB.BudgetAmt) TB"+
                " WHERE tb.Company = NVV AND TB.fiscalyear = '2017' AND tb.fiscalperiod BETWEEN 1 AND 10 and tb.segvalue1 = '4450'";
