问题描述
我已经在c#点网中编写了此更新语句
I have written this Update statment in c# dot net
string va=d1.SelectedItem.Value;
//ta1.Value=va;
com=con.CreateCommand();
com.CommandText="UPDATE notification SET notice = '" + ta1.Value + "' where id='" + va + "'";
给出bt错误
查询表达式中的
bt error are given
Syntax error (missing operator) in query expression ''This is Kamna Charitable Trust for the country INDIA working in all over India and also nebhour's country.' where id='3''.
推荐答案
您的字符串中包含''字符，sql server将其作为字符串的开始和结束指示符.您将不得不使用''''(在字符串中加倍).
请改用以下行:
Your string has the '' character in it which sql server takes as a string begin and end deliminator. You will have to use '''' (double in your string).
Use the following line instead :
com.CommandText="UPDATE notification SET notice = '" + ta1.Value.Replace("\'","\'\'") + "' where id='" + va + "'";
