找不到缺少的运算符 sql oledb vb.net [重复]

Question

当我运行以下查询时，查询表达式中出现语法错误。 当我使用 sqlclient 并从 sql server .mdf 文件读取时，这个确切的代码有效。但是现在我正在从一个 ms 访问 .mdb 文件中读取，它给了我一个缺少运算符的错误

Dim Adapter As New OleDbDataAdapter
Dim Data As New DataTable
Dim SQL As String
Dim con As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\Shantara Production IT.mdb")
Dim cmd As New OleDbCommand()
grdvbatchprodn.Visible = True
SQL = "SELECT [KN - ProductionOrderDetails].BatchNo, 
              [GN - EntityMaster].EntityName, 
              [FG - End Product Codes].ProductCode,
              SUM([KN - ProductionOrderDetails].ProductionQty) AS [Batch Total Panels],
              [KN -Special Instructions Master].SpecialInstructionDetail,
              [KN - ProductionOrderHeader].KnittBatchComplete 
        FROM [KN - ProductionOrderDetails] INNER JOIN [KN - KnittingOrder]      
            ON  [KN - ProductionOrderDetails].KnittingOrderID = [KN - KnittingOrder].KnittingOrderID
        INNER JOIN [GN - EntityMaster] 
            ON [GN - EntityMaster].EntityID = [KN - KnittingOrder].EntityID 
        INNER JOIN [KN -Special Instructions Master] 
            ON [KN -Special Instructions Master].SpecialInstructionID = [KN - KnittingOrder].SpecialInstructionID
        INNER JOIN [KN - ProductionOrderHeader] 
            ON [KN - ProductionOrderHeader].BatchNo = [KN - ProductionOrderDetails].BatchNo 
        INNER JOIN [FG - End Product Codes] 
            ON [FG - End Product Codes].ProductID = [KN - ProductionOrderHeader].ProductID
        INNER JOIN [KN - KnittingDetailsHeader] 
            ON [KN - KnittingDetailsHeader].BatchNo = [KN - ProductionOrderDetails].BatchNo
        WHERE [KN - ProductionOrderHeader].KnittBatchComplete = 0
        GROUP BY [KN - ProductionOrderDetails].BatchNo, [GN - EntityMaster].EntityName, [FG - End Product Codes].ProductCode, [KN -Special Instructions Master].SpecialInstructionDetail, [KN - ProductionOrderHeader].KnittBatchComplete
        ORDER BY [KN - ProductionOrderDetails].BatchNo, [GN - EntityMaster].EntityName;"
        con.Open()
        cmd.Connection = con
        cmd.CommandText = SQL

        Adapter.SelectCommand = cmd
        Adapter.Fill(Data)

        grdvbatchprodn.DataSource = Data
        grdvbatchprodn.DataBind()
End Sub

错误是：

System.Data.OleDb.OleDbException 发生 HResult=0x80040E14
查询表达式'[KN - 中的消息=语法错误（缺少运算符） ProductionOrderDetails].KnittingOrderID = [KN - KnittingOrder].KnittingOrderID INNER JOIN [GN - EntityMaster] ON [GN - EntityMaster].EntityID = [KN - KnittingOrder].EntityID INNER JOIN [KN -Special Instructions Master] ON [KN -Speci'.

只需添加一点格式并使用别名，这堵文字墙就变得非常易于管理。我会尝试弄清楚您是否可以更改这些表名，以便它们没有空格和其他保留字符。这在 Access 中应该可以正常工作。

SELECT pod.BatchNo, 
    em.EntityName, 
    epcProductCode,
    SUM(pod.ProductionQty) AS [Batch Total Panels],
    sim.SpecialInstructionDetail,
    poh.KnittBatchComplete 
FROM [KN - ProductionOrderDetails] as pod
INNER JOIN [KN - KnittingOrder] as ko ON  pod.KnittingOrderID = ko.KnittingOrderID
INNER JOIN [GN - EntityMaster] as em ON em.EntityID = ko.EntityID 
INNER JOIN [KN -Special Instructions Master] as sim ON sim.SpecialInstructionID = ko.SpecialInstructionID
INNER JOIN [KN - ProductionOrderHeader] as poh ON poh.BatchNo = pod.BatchNo 
INNER JOIN [FG - End Product Codes] as epc ON epcProductID = poh.ProductID
INNER JOIN [KN - KnittingDetailsHeader] kdh ON kdhBatchNo = pod.BatchNo
WHERE poh.KnittBatchComplete = 0
GROUP BY pod.BatchNo
    , em.EntityName
    , epcProductCode
    , sim.SpecialInstructionDetail
    , poh.KnittBatchComplete
ORDER BY pod.BatchNo
    , em.EntityName;
