   前两天在做网站时需要手动分页分页显示的存储过程(sqlserver 2k).一开始用的是 SqlDataAdapter 的 public int Fill(DataSet, int, int, string); 但后来发现数据量一但很大时服务器的内存增长非常快分页显示的存储过程(sqlserver 2k). 原因在这个 DataSet 包含的记录数将不会多于由maxRecords 指示的记录数。但仍然从服务器返回该查询所生成的整个结果集。分页显示的存储过程(sqlserver 2k)
    最后只能改为sql存储过程(其实也是在网上抄来的分页显示的存储过程(sqlserver 2k)). --这是分面的存储过程

    最近在关注sql server2005 ,其t-sql增强方面改了很多,而且网上也有网友写了相对应的分页代码,简单了很多,很值得一试噢。

How to use MySQL functions for data processing and calculationHow to use MySQL functions for data processing and calculationApr 29, 2025 pm 04:21 PM

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

An efficient way to batch insert data in MySQLAn efficient way to batch insert data in MySQLApr 29, 2025 pm 04:18 PM

Steps to add and delete fields to MySQL tablesSteps to add and delete fields to MySQL tablesApr 29, 2025 pm 04:15 PM

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

How to analyze the execution plan of MySQL queryHow to analyze the execution plan of MySQL queryApr 29, 2025 pm 04:12 PM

Use the EXPLAIN command to analyze the execution plan of MySQL queries. 1. The EXPLAIN command displays the execution plan of the query to help find performance bottlenecks. 2. The execution plan includes fields such as id, select_type, table, type, possible_keys, key, key_len, ref, rows and Extra. 3. According to the execution plan, you can optimize queries by adding indexes, avoiding full table scans, optimizing JOIN operations, and using overlay indexes.

How to use MySQL subquery to improve query efficiencyHow to use MySQL subquery to improve query efficiencyApr 29, 2025 pm 04:09 PM

Subqueries can improve the efficiency of MySQL query. 1) Subquery simplifies complex query logic, such as filtering data and calculating aggregated values. 2) MySQL optimizer may convert subqueries to JOIN operations to improve performance. 3) Using EXISTS instead of IN can avoid multiple rows returning errors. 4) Optimization strategies include avoiding related subqueries, using EXISTS, index optimization, and avoiding subquery nesting.

mPDF

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),
