我在Code Igniter模型中使用下面的代碼從數據庫中提取數據。但是,我的數據庫有2個Cust_Phone字段。我想設置它,以便當用戶輸入一個號碼電話字段進行搜索。我覺得有一種方法,使用像一個變量的多個字段的MySQL查詢
select distinct Phone from
(SELECT Cust_Phone1 AS Phone
FROM Customer
UNION
SELECT Cust_Phone2 AS Phone
FROM Customer) as t where Phone <> ''
在我的其他選擇查詢森那件事做到這一點在MySQL查詢,但我不知道該如何去這或如果我連這樣做的正確方法。
---笨型號功能---
public function customerQuery($First,$Last,$Zip,$Phone) {
$sql = "SELECT * FROM Customer WHERE Cust_First LIKE ? AND Cust_Last LIKE ? AND Cust_Zip LIKE ? AND Cust_Phone1 Like ?";
if($First == null || $First == '') {
$First = '%';
}else{
$First = '%' . $First . '%';
}
if($Last == null || $Last == '') {
$Last = '%';
}else{
$Last = '%' . $Last . '%';
}
if($Zip == null || $Zip == '') {
$Zip = '%';
}else{
$Zip = '%' . $Zip . '%';
}
if($Phone == null || $Phone == '') {
$Phone = '%';
}else{
$Phone = '%' . $Phone . '%';
}
$query = $this->db->query($sql, array($First,$Last,$Zip,$Phone));
return $query->result();
}
