我不知道爲什麼,當過我點擊更新按鈕,我在UPDATE語句得到一個錯誤 語法錯誤錯誤消息:在查詢表達式語法錯誤(缺少操作員)

我沒有知道什麼地方出了錯在我的代碼

這是我的代碼:

Public Class Form1 
Private Function vld(ByVal ParamArray ctl() As Object) As Boolean 
    For i As Integer = 0 To UBound(ctl) 
     If ctl(i).text = "" Then 
      ErrorProvider1.SetError(ctl(i), ctl(i).tag) 
      Return False 
      Exit For

看看這可以幫助你:

.CommandText = "Update [edit$] set [Family Name] = '" & TxtFamilyname.Text & "' where ID = '" & TxtId.Text & "' and [Given Name] = '" & TxtGivenname.Text & "' and Gender = '" & TxtGender.Text & "' and DOB = '" & TxtDob.Text & "' and [Exam Date] = '" & TxtExamdate.Text & "' and [Exam Time] = '" & TxtExamtime.Text & "' and [Street Name] = '" & TxtStreet.Text & "' and [House Nr] = '" & TxtHouse.Text & "' and PLZ = '" & TxtPlz.Text & "' and CITY = '" & TxtCity.Text & "'" 

改變我做:在

  • 增加空間值和與關鍵字
  • 添加缺少的字段名和值之間的等號(例如,TxtExamdate.Text & "'and [Exam Time]「和」前需要有一個空格)(例如之間, and [Exam Date]'" & TxtExamdate.Text應該看起來更像and [Exam Date] = '" & TxtExamdate.Text
  • 擺脫了多餘的括號

,如果你仍然有問題,考慮到要插入的字符串(這可能potentiall y包含文本框中的任何可打印字符(以及不可打印的字符!),直接放入您的語句中。如果這些字符串包含非法字符(例如,單引號或雙引號),它們將更改UPDATE語句的含義,並可能使語法無效。之前已經建議(在other question)您應該使用parametrized queries。最後,如果任何表列不是字符串(如「ID」),則可能會得到數據類型不匹配錯誤,因爲您將它們全部作爲字符串發送(用雙引號括起來)。
