Question

System.Data.SqlClient.SqlException: '' 附近有语法错误。

string olb = Request.QueryString["lb"];
string oid = Request.QueryString["id"];
String xwstrSQL = "select * from '"+olb+"'where id = '"+oid+"'";
DataTable dt = DbManager.ExecuteQuery(xwstrSQL);

Answer 1

olb前后不要加单引号，即：

String xwstrSQL = "select * from "+olb+" where id = '"+oid+"'";
