如何从中将数据检索到TextBox中 [英] How to retrieve the data into TextBox from

问题描述

先生您好，
我用文本框创建了PatientFirstname(P_FNAME)，用文本框创建了P_LName(lastname)，& P_MName(中间名)带有文本框，我也已经在MSSQL中创建了P_FNAME，P_MNAME，P_LNAME字段.所以我需要的是-


1.如果我在输出窗口中输入P_FName(FIRSTNAME)的文本框，则其他P_MNAME& P_LNAME必须自动显示在其文本框中.
或

2.如果我在输出窗口中输入P_MName(MIDDLENAME)的文本框，则其他P_FNAME& P_LNAME必须自动显示在其文本框中.

3.反之亦然，表示P_LNAME(姓氏).

在这里，对于所有字段(P_FNAME，P_MNAME，P_LNAME)，我已经在其中的列中输入了名称.因此，如何从MSSQL检索到那里的文本框.
< b> Plz在这方面确实帮助了我.
