Question

我正在通过Datagridview更新我的数据库。这是我的Update_Button代码：

 public void SaveDataSet(DataTable table)
{

  foreach (DataRow row in table.Rows)
  {

    SqlCommand cmd2 = new SqlCommand(
      @"update dbo.JobStatus 
        SET ShipTransmitStatus = @TransmitStatus, 
          ShipTrackingNumber = @TrackingNum, 
          Carrier = @Carrier, 
          ShipmentProcessedBy = @ProcessedBy, 
          ShipMethodTransmitted = @MethodTransmitted,
        WHERE JobTableId = @JobID ", _mySqlConnec);

    //Updated the parameters to the SQL Query!
    cmd2.Parameters.Add(new SqlParameter("@TransmitStatus", row["Status"].ToString()));
    cmd2.Parameters.Add(new SqlParameter("@TrackingNum", row["Tracking#"].ToString()));
    cmd2.Parameters.Add(new SqlParameter("@Carrier", row["Carrier"]));
    cmd2.Parameters.Add(new SqlParameter("@ProcessedBy", row["ProcessedBy"].ToString()));
    cmd2.Parameters.Add(new SqlParameter("@MethodTransmitted", row["MethodTransmitted"].ToString()));
    cmd2.Parameters.Add(new SqlParameter("@JobID", row["JobID"].ToString()));

    cmd2.Connection = _mySqlConnec;
    _mySqlConnec.Open();
    cmd2.ExecuteNonQuery();
    _mySqlConnec.Close();
  }


}

这是我的SELECT语句：

SELECT dbo.InvoiceLineDetail.JobNumber as Job#,dbo.InvoiceLineDetail.PatientName,
       dbo.InvoiceLineDetail.CustomerAccountName as Name, COALESCE(InvoiceLineDetail.ShipAddressAddr2 + ' ','') + COALESCE(InvoiceLineDetail.ShipAddressAddr3+' ','') as Address,
       dbo.InvoiceLineDetail.ShipAddressCity as City, dbo.InvoiceLineDetail.ShipAddressState as State,
       dbo.InvoiceLineDetail.ShipAddressPostalCode as ZipCode, dbo.InvoiceLineDetail.ShipAddressCountry as Country , dbo.JobStatus.ShipTransmitStatus as Status, dbo.JobStatus.ShipTrackingNumber as Tracking#, dbo.JobStatus.Carrier, dbo.JobStatus.ShipMethodTransmitted as MethodTransmitted,
       dbo.JobStatus.DateShipTransmitProcessed as DateProcessed, dbo.JobStatus.ShipmentProcessedBy as ProcessedBy, dbo.JobStatus.Critical,  dbo.JobStatus.JobTableId as JobID, dbo.JobStatus.InvoiceStatus,
       dbo.InvoiceLineDetail.Quantity, dbo.InvoiceLineDetail.ChargeGroup
       FROM dbo.InvoiceLineDetail INNER JOIN
       dbo.View_JobsToShipCount ON dbo.InvoiceLineDetail.CustomerAccountName = dbo.View_JobsToShipCount.CompanyName INNER JOIN
       dbo.JobStatus ON dbo.InvoiceLineDetail.JobID = dbo.JobStatus.JobTableId
       WHERE (dbo.InvoiceLineDetail.ChargeGroup = N'Lens')

我收到错误：'WHERE'附近的语法不正确。可以找出问题所在：（

Answer 1

从以下位置删除最后一个逗号：

ShipMethodTransmitted = @MethodTransmitted,

即。将其更改为：

ShipMethodTransmitted = @MethodTransmitted

作为这类错误的一般答案：

查看错误消息中建议的关键字附近。
如果您的错误消息为您提供了一条错误的行。线

这正是我现在所做的。我看着附近的地方，看到了额外的逗号。

Answer 2

ShipMethodTransmitted = @MethodTransmitted,

删除@Method之后的逗号...

Answer 3

在SaveDataSet函数中，SQL命令在WHERE子句之前有一个额外的逗号。

'WHERE'附近的语法不正确
