Question

在我的更新查询中，我在以下代码中收到更新语法错误....

Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
    Dim strup As String
    Try
        strup = "update MCA set urno=" & CInt(txtUrn.Text) & ",sname='" & txtName.Text & "',fname='" & txtFname.Text & "',CAddress='" & txtCAdd.Text & "',PAddress='" & txtPAdd.Text & "',EmailID='" & txtEid.Text & "',cmbdate=" & CInt(cmbDate.Text) & ",cmbmonth='" & cmbMonth.Text & "',cmbyear=" & CInt(cmbYear.Text) & ",Gender='" & cmbGender.Text & "',Mobile" & CLng(txtMno.Text) & ",10PSSC=" & CInt(txt10Per.Text) & ",12PHSC=" & CInt(txt12Per.Text) & ",10YSSC='" & cmb10YofPass.Text & "',12YHSC='" & cmb12YofPass.Text & "',Course='" & cmbNameofGCourse.Text & "',gper=" & CInt(txtGPer.Text) & " WHERE urno =" & (txtUrn.Text) & ";"
        Dim command As New OleDb.OleDbCommand(strup, con)
        command.ExecuteNonQuery()
        con.Open()
        con.Close()
        MsgBox("Record Updated")

    Catch ex As Exception
        MsgBox(ex.ToString())
    End Try
End Sub

Answer 1

尝试：

strup = "update MCA set urno=" & CInt(txtUrn.Text) & ",sname='" & txtName.Text & "',fname='" & txtFname.Text & "',CAddress='" & txtCAdd.Text & "',PAddress='" & txtPAdd.Text & "',EmailID='" & txtEid.Text & "',cmbdate=" & CInt(cmbDate.Text) & ",cmbmonth='" & cmbMonth.Text & "',cmbyear=" & CInt(cmbYear.Text) & ",Gender='" & cmbGender.Text & "',Mobile=" & CLng(txtMno.Text) & ",10PSSC=" & CInt(txt10Per.Text) & ",12PHSC=" & CInt(txt12Per.Text) & ",10YSSC='" & cmb10YofPass.Text & "',12YHSC='" & cmb12YofPass.Text & "',Course='" & cmbNameofGCourse.Text & "',gper=" & CInt(txtGPer.Text) & " WHERE urno =" & (txtUrn.Text) & ";"

您有"',Mobile" & CLng(txtMno.Text)而不是"',Mobile=" & CLng(txtMno.Text)

Answer 2

与上述答案相同，并且在最后一个值上是附加的 WHERE urno =" & (txtUrn.Text) & ";"表示数字或文字。

如果它是数字你应该转换它或它是文本然后你应该把它作为
WHERE urno ='" & (txtUrn.Text) & "';"

这就是您的查询的样子。

strup = "update MCA set urno=" & CInt(txtUrn.Text) & ",sname='" & txtName.Text & "',fname='" & txtFname.Text & "',CAddress='" & txtCAdd.Text & "',PAddress='" & txtPAdd.Text & "',EmailID='" & txtEid.Text & "',cmbdate=" & CInt(cmbDate.Text) & ",cmbmonth='" & cmbMonth.Text & "',cmbyear=" & CInt(cmbYear.Text) & ",Gender='" & cmbGender.Text & "',Mobile=" & CLng(txtMno.Text) & ",10PSSC=" & CInt(txt10Per.Text) & ",12PHSC=" & CInt(txt12Per.Text) & ",10YSSC='" & cmb10YofPass.Text & "',12YHSC='" & cmb12YofPass.Text & "',Course='" & cmbNameofGCourse.Text & "',gper=" & CInt(txtGPer.Text) & " WHERE urno ='" & (txtUrn.Text) & "';"
