代码如下:
query3.Close;
query3.SQL.Clear;
query3.SQL.Add('select sendtime,fromname,msg from smsg where (read1=1) and (sendto='''+ 'F2'')');
showmessage(Query3.SQL.Text);
query3.Open;
showmessage(inttostr(query3.RecordCount)); //总是显示为-1
执行select sendtime,fromname,msg from smsg where (read1=1) and (sendto= 'F2') 得到12条结果
