The following articles mainly describe the actual operation process of MySQL index and query optimization. We all know that MySQL index and query optimization have a high proportion in actual operations, so a deeper understanding of it will gain some gains in your future studies.

What ColdFusion is.
ColdFusion (literal: Cold fusion) is a dynamic Web server whose cfml (ColdFusion Markup Language) is a programming language, similar to JavaServer in Jstl page (JSP Standard Tag Lib), began to develop from 1995, its design thought by some people think very advanced, by some language reference.Coldfusion was originally an application server platform developed by Allaire Corporation, and its CFML (Coldfusion Markup Language) is a scripting language for Web applications. Files a
errors, and verification errors. Sort by the importance of these errors. The first error is the application server environment error. These errors are generated by the application server, which may cause the entire coldfusion application to fail to run. Therefore, it is the most important position. For other errors, we should try to reduce syntax and logic errors because such errors can be corrected through continuous debugging, and debugging of such errors consumes more energy.

For example, the default implementation of a stream is in the file src/base/ftsystem. C and the ANSI fopen/fseek and fread functions are used. However, in the Unix Version of FT2, another implementation using memory ing files is provided, which can greatly increase the speed of the host system.
FT distinguishes between memory-based and disk-based streams. For the former, all data is directly accessed in the memory (for example
