php - 如何从日期范围 PHP 中获取年数

Question

我有许多使用日期格式的日期范围的日期。现在，我想从那个日期起只有几年。

比方说某人，给出日期范围从:01-01-2010 到 09-05-2019。

我想从这个日期起只有年，所以我将把它们包括在我的 sql 查询中。

如果在今年指定范围内，查询仅适用于 2015，但我如何才能只在范围内的所有年份使用它？

这里是查询:

$sql = "SELECT
    MONTH (transaction_date),
    SUM(case when finance_type != 'Deposit' then amount else 0 end) AS total_amount,
    SUM(case when finance_type = 'Deposit' then amount else 0 end) AS deposit,
    SUM(case when finance_type != 'Deposit' AND amount < 0 then amount else 0 end) AS expenses,
    SUM(case when finance_type != 'Deposit' AND amount > 0 then amount else 0 end) AS earning,          
    SUM(case when finance_type != 'Deposit' AND amount!='' then num_contract else 0 end) AS total_contracts,
    transaction_date  
      FROM 
        `tbl_finanace`
            WHERE
                transaction_date LIKE '%2015%'
            AND user_id = '15'
                GROUP BY
            MONTH (transaction_date)
                ORDER BY
            MONTH (transaction_date)";

Answer 1

如果是 DATETIME 字段，您可以使用小于和大于。

where transaction_date <= '2010-01-01 00:00:01' and transaction_date >= '2005-12-31 23:59:59'
