Oracle 特殊字符处理 查找 替换

   前几天有个同事遇到个特殊字符匹配替换的问题,这里总结一下。如果我们数据里面含有换行、回车等特殊字符时怎么处理?

1、 Replace函数的使用

这里我们需要使用到两个函数chrascii

先用ascii函数查出特殊字符的ascii值,或者直接查看ascii表,,比如我们知道换行是10;回车是13

2、 regexp_replace函数的使用

我们也可以用这个来查询含有特殊字符的列:(这里认为数字和字母以为的都是)

select t.*, t.rowid

3、 结合使用

特别是我们要处理其它输入法字符时(比如俄文字符),我们可以结合来使用,先查询数字、字母、空格、标点符号以为的字符。

select *

,

我们可以查看结果中有‘om’其中’ к’应该是’k’,因此我们可以查询ascii

----- 53434(结果)

这样可以实现误输入其它字符的替换。

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata.

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
