如何更新数据库的所有行上的特定列

问题描述 投票：-1回答：2

我必须在用户在上一个日期创建新条目时更新列opcash我必须更新prev日期opcash列，并且今天还要opcash列，其中opcash是总信用额的总和 - 总借记金额的总和。并且当用户输入信用栏时，必须添加opcash总额，并且当用户在借记栏上输入金额时必须减去该过程，该过程将持续所有日子。我的问题是opcash值是正确的如果用户在连续的一天创建一个条目，如果用户在25-12-2018,26-12-2018,27-12-2018创建条目，则用户继续正确的顺序。如果用户在18-12-2018创建一个条目，如果用户在25-12-2018创建一个条目，opcash值将在25-12-2018更新，但不会在26-12-2018更新。请帮我改变用户在前一天创建新条目时的opcash值

尝试更改查询中的日期格式。通常表中的日期格式为Y-m-d：

$newDate = date("Y-m-d", strtotime($date));

我创建了一个SQLFiddle来展示如何在不必维护该表的情况下获得与daytot表相同的结果。它还将日期列显示为DATE类型而不是VARCHAR。

通过在表中使用DATE类型而不是VARCHAR，可以防止将来出现几个可能的问题。它还允许您正确地按日期排序和选择，选择日期范围等。它还消除了与将行插入日历表时相关的任何问题，并处理对日记表的更新和删除。

查询1：

SELECT

  SUM(IF(`dc` = 'c',`amount`,0)) as `total_credit`,
  SUM(IF(`dc` = 'd',`amount`,0)) as `total_debit`,
  SUM(IF(`dc` = 'c',`amount`,0)) - SUM(IF(`dc` = 'd',`amount`,0)) as `opcash`,
  0 as `clcash`

GROUP BY `date`

Results：
