oracle 12c查看执行过的sql及当前正在执行的sql

2.PARSING_SCHEMA_NAME显示的是哪个用户执行的该sql，而不是这个sql操作的表属于哪个schema。当执行新的SQL语句时，如果这条SQL语句不在共享池中，数据库会进行硬解析，并将解析后的执行计划加载到共享池中。如果执行的是共享池内已经存在的SQL语句，则只会进行软解析，LAST_LOAD_TIME的值不会改变。假如同事让排查某个接口都有哪些慢sql，可以使用这个方法（先调用下这个慢接口，然后统计下这个时间段内的慢sql），只是会导出非这个接口的多余慢sql，再结合业务进行筛选吧。
SQL 注入详解：原理、危害与防范措施
2509_94107200的博客
11-24 544
SQL注入是一种常见的安全漏洞，攻击者通过在应用程序中插入恶意的SQL代码，诱使数据库执行非授权的操作。这种攻击通常发生在应用程序没有正确过滤或转义用户输入的情况下，导致攻击者能够操控数据库查询，从而获取、修改或删除数据。SQL注入是一个严重的安全问题，开发者必须采取有效措施来预防。使用预编译语句、严格验证用户输入、遵循最小权限原则等都是防范SQL注入的有效手段。此外，定期的安全审查和测试也是保障应用安全的重要环节。通过这些措施，可以大大降低SQL注入的风险，保护应用程序和用户数据的安全。
SQL视图使用
2509_93948268的博客
11-23 354
当然，也要时刻注意其可能带来的性能影响，在复杂场景下，可以考虑使用物化视图（Materialized View，并非所有数据库都支持）或其他缓存策略来弥补性能短板。而如果应用程序访问的是视图，那么只要视图的结构保持不变（通过修改视图定义来适配底层表的变化），应用程序就无需任何改动。性能问题：视图本身不存储数据，每次查询视图，本质上都是在执行定义它的那条SQL语句。将复杂的连接、子查询、聚合函数等逻辑封装在视图内部，上层应用和用户只需要面对一个简单的表结构，大大降低了SQL的编写难度和理解成本。
