主题：[求助]用SQL直接筛选某列内容长度

Dim cmd As new SQLCommand
cmd.C
cmd.CommandText = "se lect * from {订单表} " 
Dim Sdt As DataTable = cmd.ExecuteReader
For Each dr As DataTable In sdt.DataRows
    If dr("地址").Length > 14 Then r("超长") = "Y"
Next

老师，以上是将订单表中客户地址中超过14个字的找出来，能不能直接用SQL直接就加载进来，不用循环，数据量比较大，不好循环。

cmd.CommandText = "se lect * from {订单表} where [地址]Length > 14

where len([地址]) > 14
