更新mysql查詢不更新表，但只刪除指定字段中的數據

Question

我的更新查詢有問題，它不更新指定的字段，但只刪除它們。

這是查詢：

Dim myConnection As OdbcConnection 
Dim myCommand As OdbcCommand 


myConnection = New OdbcConnection("DRIVER={MySQL ODBC 3.51 Driver};Database=usermanagement;Server=localhost;UID=root;") 
myConnection.Open() 

If myConnection.State = 0 Then 
    myConnection.Open() 
End If 


myCommand = New OdbcCommand("update rooms set rmname='" + Request.Form("rmnames") + "',description='" + Request.Form("description") + "', rmprice='" + Request.Form("rmprices") + "' where room_id='" + Request.Form("rooms_id") + "'", myConnection) 
myCommand.ExecuteNonQuery() 
myConnection.Close() 

Response.Redirect("admin.aspx") 

感謝您的幫助。
