本文介绍了SQL中的两种字符串替换函数：replace和translate。通过实例对比了两者的不同之处，replace适用于简单的字符串替换，而translate能够对查找字符串中的每个字符进行一一对应的替换。

replace 就是通常意义的字符串替换函数

translate是一种字符替换函数,它是把每一个查找字符串中的字符替换成替换字符串中的对应字符.

测试结果:

select replace('kkaxksx', 'kx', '12') from dual

结果:kkaxksx

select TRANSLATE('kkaxksx', 'kx', '12') from dual

结果:11a21s2

确定要放弃本次机会？

一、“like '%%'”的优化，建议使用instr(?,?)效率高单表有超大数量级的数 1、oracle和mysql中如果有索引的情况下，使用like 'aa%'或者like '%aa'效率较高，因为如果是like "%aa%"那么会导致全表扫描！效率非常低！如果没有索引，那么最好使用instr(stpm,字符串)函数解决问题举例： select * from xslsb ...

The difference between accuracy and recall

05-25

Accuracy and recall are both metrics used to measure the performance of a classification model. Accuracy is the ratio of correctly predicted observations to the total number of observations. It measures the overall correctness of the model's predictions. A higher accuracy score indicates that the model has made more correct predictions. Recall, on the other hand, is the ratio of the correctly predicted positive observations (true positives) to the total number of actual positive observations (true positives + false negatives). It measures the ability of the model to identify all positive examples. A higher recall score indicates that the model is better at identifying positive cases. In summary, accuracy measures the overall performance of the model, while recall measures the model's ability to identify positive cases. They are both important metrics to consider depending on the specific application and goals of the model.
