Question

下面是一个代码，Visual Studio引发了WHERE附近存在语法错误的错误。

SqlCommand cmd2 = new SqlCommand("insert into courses(t_id_fk) values('" + valu3 + "') where c_id=@dr1 ", con);
cmd2.CommandType = CommandType.Text;
                cmd2.Parameters.Add("@dr1", SqlDbType.Int);
                cmd2.Parameters["@dr1"].Value = d1;
                cmd2.ExecuteNonQuery();
                con.Close();

Answer 1

插入时删除where子句：

发件人：

"insert into courses(t_id_fk) values('" + valu3 + "') where c_id=@dr1 "

以

"insert into courses(t_id_fk) values('" + valu3 + "')"

但如果上面给出的样本是update，那么：

"update courses set t_id_fk = '" + valu3 + "' where c_id=@dr1"

ASP NET中Where子句附近的错误
