The most misunderstood character in MySQL’s SQL-Dialect
(Roland Bouman) Many MySQL users like to use the MySQL monitor. The MySQL monitor is the executable bin/mysql (or if you are on MS Windows, binmysql.exe) and is perhaps better known as the MySQL command-line tool or MySQL command-line client.
Secrets of the MySQL Client Command Line
(W. Jason Gilmore) Graphically oriented MySQL administration tools abound, but for true speed and no-frills management perhaps nothing is more effective than the command-line driven MySQL client. However, the inordinate amount of typing due to executing common queries, determining what database you’
Updates & Discipline
(Martin Farach-Colton) So far, I’ve analyzed point and range queries. Now it’s time to talk about insertions and deletions. We’ll call the combination updates. Updates come in two flavors, and today we’ll cover both.

This is however not performance gotc
Using MS Access with PostgreSQL
(Leo Hsu and Regina Obe) Many in the PostgreSQL community use Microsoft Access as a front-end to their PostgreSQL databases. Although MS Access is strictly a windows application and PostgreSQL has its roots in Unix, the two go well together. A large part of that reason is because the PostgreSQL ODBC
MySQL Information Schema Plugins: the best kept secret of MySQL 5.1
(Roland Bouman) MySQL 5.1 offers an extremely useful feature called information_schema plugins. This feature allows dynamic runtime loading of a shared library into the MySQL server to implement a table in the information_schema database. The SQL standard (ISO/IEC 9075-11:2003) allows database imple
