在mysql中批量查询我们使用了like通配符,替换我们直接使用replace 与update联合使用,下面我来举实例说明。
通配符 说明
_ 与任意单字符匹配
% 与包含一个或多个字符的字符串匹配
[ ] 与特定范围(例如,[a-f])或特定集(例如,[abcdef])中的任意单字符匹配。
[^] 与特定范围(例如,[^a-f])或特定集(例如,[^abcdef])之外的任意单字符匹配
批量查找:
代码如下 | 复制代码 |
SELECT a.products_name FROM nike.products_description a WHERE a.products_name like '%#%' |
#为要查找的字符串
批量替换:
REPLACE
用第三个表达式替换第一个字符串表达式中出现的所有第二个给定字符串表达式。
语法
REPLACE ( 'string_expression1' , 'string_expression2' , 'string_expression3' )
参数
'string_expression1'
待搜索的字符串表达式。string_expression1 可以是字符数据或二进制数据。
'string_expression2'
待查找的字符串表达式。string_expression2 可以是字符数据或二进制数据。
'string_expression3'
替换用的字符串表达式。string_expression3 可以是字符数据或二进制数据。
代码如下 | 复制代码 |
UPDATE article SET content = replace(content, ’sjolzy’, ’sjolzy.cn') WHERE name like '%#%'; |
article为表 content为字段 sjolzy为要被替换的 sjolzy.cn为替换的值

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. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
