SQL菜鸟级的问题
string str_sql = "delete from news where ID = ' "+Convert.ToInt32(txt_ID.Text.Trim())+ " ' ";
提示数据类型不匹配,我觉得匹配着呀
ID是ACCESS中的长整型

[解决办法]
string str_sql = "delete from news where ID = " Convert.ToInt64(txt_ID.Text.Trim())+ " ' ";

[解决办法]
string str_sql = "delete from news where ID = "+ Convert.ToInt64(txt_ID.Text.Trim);

你ID是整型, ' " " '这个是字符型了呀
