ASPX Long Selectcommand

Question

我知道这必须在某处发布，我可能不会用正确的措辞进行搜索，但是你如何分解一个长的selectcommand语句以便你可以看到它？我的页面正在运行，很难阅读。提前谢谢！

Answer 1

如果你正在使用c＃，你可以这样做：

SqlCommand sqlcmd = new SqlCommand("SELECT TopicsTitle,TopicContents,UserName,Avatar,NumberOfPost,uPoints,uType " +
                                 "FROM Topic, Registration " +
                                "WHERE Topic.Category ='" + ilblTopic.Text + "'" +
                                  "AND LastPostDate ='" + DateTime.Parse("...") + "'");

加分：请使用parameterized query.

您可以使用字符串构建器来创建长字符串。

System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("SELECT field1, field2, field3 as Field3_Something,");
sb.Append(field4, field5, field6, field7, field8, field9");
sb.Append(FROM table JOIN table2 AS TNS ON TNS.id = table.id");
sb.Append(" WHERE something = 1");
SqlCommand sqlcmd = new SqlCommand(sb.ToString());
