Question

我有一张表如下：（transactions_filter）：

+----+------------------------------+------------+--------------------------+
| ID | ContactName                  | account_id | Expression               |
+----+------------------------------+------------+--------------------------+
|  1 | Salaries & Wages             |    6123372 | SH\-01\-[0-9]*?\-477\-0  |
|  2 | Salaries & Wages             |    6123372 | SH\-01\-00000001\-550\-0 |
|  3 | Salaries & Wages             |    6123372 | SH\-01\-00000001\-551\-0 |

然后我的交易看起来如下:(账户）

现在，如何在不循环遍历每个过滤器的情况下将事务与我的过滤器匹配，如下所示：

    $filters = \App\Models\Transaction\Filter::All();   
    $transactions = \App\Models\Transaction::All();

    $data = [];
    foreach($transactions as $transaction)
    {
        foreach($filters as $filter)
        {
            if(preg_match("/" . $filter->Expression . "/", $transaction->description))
            {
                $data[] = [
                    'date' => $transaction->date,
                    'ContactName' => $filter->ContactName,
                    'account_id' => $filter->account_id,
                ];
            }
        }
    }

    dd($data);

您可以使用FULL OUTER JOIN和RLIKE，如下所示：

SELECT * FROM transactions_filter f, transactions t
WHERE t.Description RLIKE f.Expression

以下是要测试的SQL小提琴：http://sqlfiddle.com/#!9/ba827e/1

注意：?中存在的Expression无法与RLIKE一起使用，其余正则表达式正常。

Mysql正则表达式使用多个规则来匹配字符串
