细心的开发人员有时会想到,我们在一个需要读写数据库的页面里包含类似!-- #include file="conn.asp" --的代码时,实际上,当你没有进行任何读写数据库操作时,这个数据库连接仍然是打开的,仍然在消耗着服务器的资源。 那么,我们有没有办法让数据库连接仅

  细心的开发人员有时会想到,我们在一个需要读写数据库的页面里包含类似的代码时,实际上,当你没有进行任何读写数据库操作时,这个数据库连接仍然是打开的,仍然在消耗着服务器的资源。

  那么,我们有没有办法让数据库连接仅在需要读取数据库时才打开,不读取时就没有任何动作呢,以下即提供这种思路,以求抛砖引玉。

  这种思路即是将数据库连接代码封装在函数里,在需要读取时调用这个函数。

  以下是SQL连接代码:

 Function Open_conn()
  dim Conn,Strconn
  set Conn=server.createobject("adodb.connection")
  Strconn = "Provider = Sqloledb; User ID = 数据库登录帐号; Password = 数据库登录密码; Initial Catalog = 数据库名称; Data Source = (local);"
  Conn.open Strconn
  set Open_conn=Conn
  If Err Then
  err.Clear
  Conn.close:set Conn=nothing
  Response.Write "对不起,数据库连接出错。"
  Response.End
  End If
  End Function

 调用方法:

 将原来的

 rs.open sql,conn

 改成

 rs.open sql,Open_conn()

MySQL BLOB: how to optimize BLOBs requestsMySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AM

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.

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.

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),
