我在sql中有一个表

< br /> Sl |等级|备注< br /> 1 | A | ggggggggggggggggggg< br /> 2 | B | ddddddddddddddddddddd< br /> 3 | C | dddddddddxxxxxxxxxx< br /> 4 | D | rrrrrrvvvvvvvvvvvvv< br />

现在我的问题是通过填写datagridview1文本框中的Sl来从sql表中检索成绩。 如果我在datagridview文本框列填充2（SL） SL |等级|备注 2 | | 然后它应该从sqltable中检索它的等级

< br /> Sl |等级|备注< br /> 2 | B | ddddddddddddddddddddddddddddddddddddddddddddddddddbdbd bd bb b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b /> ............................................ ......
