Answer 1

您需要包含一组ORed条件。

sql = "Select * from solarleads 
where ( Phone = '" + c_id.Text + "' OR AgentName Like '" + c_id.Text + "%' 
OR CallStatus Like '%" + c_id.Text + "%' 
OR CenterId = '" + c_id.Text + "' ) 
And Date >= '" + date1.Text + "' AND Date <='" + date2.Text + "' 
ORDER BY Id DESC ;"

Answer 2

用括号分隔和条件，如 -

sql = "Select * from solarleads where " +
"(Phone = '" + c_id.Text + "' " +
  "OR AgentName Like '" + c_id.Text + "%' " +
  "OR CallStatus Like '%" + c_id.Text + "%' " +
  "OR CenterId = '" + c_id.Text + "' ) " +
"(And Date >= '" + date1.Text + "' AND Date <='" + date2.Text + "' )" +
"ORDER BY Id DESC ;";
