value of the field to be null when the database is designed.3. Using a short indexIndex A string, or specify a prefix length if possible. For example, if you have a column of char (255), and if the majority value is unique within the first 10 or 20 characters, do not index the entire column. Short indexes not only improve query speed but also save disk space and I/O operations.4. Index column SortingThe MySQL query uses only one index, so if an index

Tags: BSP between www order by database table ble www. Null data pageIndex:Use an index to quickly access specific information in a database table. An index is a structure that sorts the values of one or more columns in a database table, such as the last Name column of an employee table. If you want to find a specific employee by last name, the index will help you get that information faster than if you have to search all the rows in the table.An index is a separate, physical database structure

The Django version used in this blog post is 1.4.0 (recently using SAE, no way, had to withdraw from 1.7.1). But the principle is probably similar.Django supports a variety of database management tools such as MySQL, PostgreSQL, SQLite, and Oracle. Where SQLite is built into Python, so if you use SQLite, you do not have to configure the configuration, the full use of Python to manage, of course, do not have to look at the Ben Boven.This blog post takes MySQL as an example to demonstrate the "loc

advantages over it. Slowly, everyone likes to use the shared function library. However, in some places the static function library is still in use, one to maintain some of the previous program compatibility, and secondly, it is relatively simple to describe.The static library function allows the programmer to link the program without recompiling the code, saving the time to recompile the code. However, in the face of such a fast computer today, the general program of the recompile will not take

It uses the TCP protocol stack Tcp_diag (is a module for analyzing statistics), can directly from the first-hand kernel information, which makes the SS
