问题描述

AM尝试更新,但在'='附近得到此错误

语法


我是什么尝试过:



 con =新SqlConnection(cs)
con.Open()
Dim cb As String =更新CourseFeePayment设置CFP_ID = @ d1,PaymentID = @ d2,AdmissionNo = @ d3,Session = @ d4,TotalFee = @ d6,DiscountPer = @ d7,DiscountAmt = @ d8,PreviousDue = @ d9,罚款= @ d10,GrandTotal = @ d11,TotalPaid = @ d12,ModeOfPayment = @ d13,PaymentModeDetails = @ d14,PaymentDue = @ d16其中CFP_ID ='& txtCFPId.T​​ext& '
cmd =新SqlCommand(cb)
cmd.Connection = con
cmd.Parameters.AddWithValue(@ d1,Val(txtCFPId.T​​ext))
cmd .Parameters.AddWithValue(@ d2,txtFeePaymentID.Text)
cmd.Parameters.AddWithValue(@ d3,txtAdmissionNo.Text)
cmd.Parameters.AddWithValue(@ d4,txtSession。文本)
cmd.Parameters.AddWithValue(@ d6,txtCourseFee.Text)
cmd.Parameters.AddWithValue(@ d7,txtDiscountPer.Text)
cmd.Parameters.AddWithValue( @ d8,txtDiscount.Text)
cmd.Parameters.AddWithValue(@ d9,txtPreviousDue.Text)
cmd.Parameters.AddWithValue(@ d10,txtFine.Text)
cmd.Parameters.AddWithValue(@ d11,txtGrandTotal.Text)
cmd.Parameters.AddWithValue(@ d12,txtTotalPaid.Text)
cmd.Parameters.AddWithValue(@ d13, cmbPaymentMode.Text)
cmd.Parameters.AddWithValue(@ d14,txtPaymentModeD etails.Text)
cmd.Parameters.AddWithValue(@ d16,txtBalance.Text)
cmd.ExecuteNonQuery()
con.Close()
con = New SqlConnection( cs)
con.Open()
Dim cq As String =从CourseFeePayment_Join中删除,其中C_PaymentID =& txtCFPId.T​​ext&
cmd =新的SqlCommand(cq)
cmd.Connection = con
cmd.ExecuteNonQuery()
con.Close()
con.Open()
Dim cb1 As String =插入CourseFeePayment_Join(C_PaymentID,Month,FeeName,Fee)VALUES(& txtCFPId.T​​ext&,@ d1,@ d2,@ d3)
cmd = New SqlCommand(cb1)
cmd.Connection = con
'准备重复执行命令
cmd.Prepare()
'要插入的数据
For Each row As DataGridViewRow在dgw.Rows
如果不是row.IsNewRow那么
cmd.Parameters.AddWithValue(@ d1,row.Cells(0).Value)
cmd.Parameters.AddWithValue(@ d2,row.Cells(1).Value)
cmd.Parameters.AddWithValue(@ d3,Val(row.Cells(2).Value))
cmd.ExecuteNonQuery()
cmd.Parameters.Clear()

           cmd = New SqlCommand(cb)
           cmd.Connection = con
           cmd.Parameters.AddWithValue("@d1", Val(txtCFPId.Text))
