SQL: Tips of the Day

Is SQL syntax case sensitive?

The SQL Keywords are case-insensitive (SELECT, FROM, WHERE, etc), but are often written in all caps. However in some setups table and column names are case-sensitive. MySQL has a configuration option to enable/disable it. Usually case-sensitive table and column names are the default on Linux MySQL and case-insensitive used to be the default on Windows, but now the installer asked about this during setup. For MSSQL it is a function of the database's collation setting.
