mysql分表后 如何分页 (总共160个表1500万数据)
mysql分表后，有160个表，有1500万数据，要怎么做分页列表？
之前是想用union all合并160个表的结果集。。但直接卡的数据都出不来。。
请问这里应该怎么做分页，谢谢~~~
------解决思路----------------------
要是整体的分页显示那就更简单了
1、每个表的记录数是已知的，应在每次发生变化时记录到目录表中
2、无论是否排序（如果排序只是表的次序不同）至多会 union 两个分表
如假定共3个分表，记录数分别为 90，120，80 总记录数为 290
设分页是每页显示40条，则
第1页 表一的 1 到 40
第2页 表一的 41 到 80
第3页 表一的 81 到 90 + 表二的 1 到 30
第4页 表二的 31 到 70
第5页 表二的 71 到 110
第6页 表二的 111 到 120 + 表三的 1 到 30
.....
计算起来非常简单

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
