php - 将 sql 查询转换为 Fluentpdo 查询

Question

我有这个用 php 编写的 sql 查询:

$query = sprintf("UPDATE bank_info SET
                      amount_dollar = amount_dollar +'$amount_dollar'  ,
                      amount_euro = amount_euro + '$amount_euro' ,
                      amount_local = amount_local + '$amount_local'
                      WHERE bank_id = '$bank_id' ");

此查询工作正常，但我想使用 FluentPDO 转换此查询。我想使用数组来设置值。例如:

$table='bank_info'; //table name
$arrVal=array();    //values needs to be SET
$arrVal['amount_dollar = amount_dollar+?']=$amount_dollar;
$arrVal['amount_euro = amount_euro+?']=$amount_euro;
$arrVal['amount_local = amount_local+?']=$amount_local;
$arrWhere=array();  //where condition
$arrWhere['bank_id']=$bank_id;

这是查询:

$query = $this->pdo->update($table)->set($arrVal)->where($arrWhere);

$query->execute();

我认为问题出在 $arrVal 中，无法找到正确的方法来 SET 并将值添加到表中列的当前值。我多次使用数组从数据库/表中选择和获取值，所以我认为 $arrWhere 不是问题。

好吧，找到答案了，

例如:

这对我有用:

$id = 5;
$field = 'stock';
$amount = 1;

$increment = array($field => new FluentLiteral($field.' + '.$amount));

$fpdo->update('products')->set($increment)->where('id', $id)->execute();
