我已对您的查询进行了重组，希望能够显着提高性能。通过使用 STRAIGHT_JOIN 告诉 MySQL 按照您所说的顺序进行操作（或者我在这里进行了调整）。最里面的第一个查询“PreQuery”别名从导入包和通用导入的标准开始，到帐户导入到帐户...通过在此处预先应用 WHERE 子句（并且正如您将测试的那样，添加您的此处限制条款）您正在预先加入这些表格，并在浪费任何时间尝试获取客户、地址等其他信息之前将它们排除在外。在查询中，我调整了联接/左联接，以更好地显示底层链接表的关系（主要供其他人阅读）。
正如另一个人指出的那样，我在 PREQUERY 中所做的可能是用于通过和页面可用的主预查询列表中的“Account.ID”记录的基础。我很想知道这对您现有的性能，尤其是在 10,000 限制范围内的性能。
PREQUERY 获取唯一元素（包括下游使用的帐户 ID、银行、月份、年份和类别），因此在加入过程的其余部分不必重新加入这些表。
