Question

怎样在delphi中数据库实现模糊查询?

memo1.Lines.Text:='select * from czpdj where czrwzy='+''''+Edit1.Text+'''';
with adoquery1 do begin
with sql do begin
close;
clear;
adoquery1.sql.Assign(memo1.lines);
end;
open
请问怎样改可以模糊查询?
把“memo1.Lines.Text:='select * from czpdj where czrwzy='+''''+Edit1.Text+''''; ”改成“memo1.Lines.Text:='select * from czpdj where czrwzy like ''%'+Edit1.Text+'%'''; ”后可输入两个字符进行查询．但无法输入更多或全部内容，查询结果是空．

memo1.Lines.Text:='select * from czpdj where czrwzy like '''+'%'+Edit1.Text+'%'+''''; 试了，还是那样！

Answer 1

memo1.Lines.Text:='select * from czpdj where czrwzy like '''+'%'+Edit1.Text+'%'+'''';

试试？
