PHP ADO ACCESS数据库,SQL怎么比较时间大小?
现在用PHP + ADO + ACCESS数据库,比较时间遇到问题
ACCESS数据库的Time字段存储的为 COleDateTime格式的时间数据。
下面二行代码为MFC 编程时写入数据库的“Time”字段的代码
COleDateTime ct=COleDateTime::GetCurrentTime();
m_pRecordset_record->PutCollect("Time",_variant_t(ct));
-------------------------------------------------------
下面是我想达到的日期筛选SQL,但实际上sqlstr这样写是有问题的,php执行错误的,想请教一下怎样写才是正确的。
$sqlstr="select * from record where NameStr='$sensor' and Time>'2014/01/15'";
$rsRecord1->Open($sqlstr,$conn1,1,1);
------解决方案--------------------
$sqlstr="select * from record where NameStr='$sensor' and Time>#2014-01-15#";

Dependency 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.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
