As a short preliminary comment: please try not to use the confusing int(10) or tinyint(3) notation. This is a MySQL (or even phpMyAdmin) specific notation that means that the integer value will be shifted to fill a corresponding display size of 10 or 3 characters. Nothing to do with the actual size of the integer in memory or on disk (which I assume you intend to represent here). Instead, use the normal ANSI SQL-standard[1] values: integer or smallint (tinyint is not *really* part of all versions of SQL and is only supported by MySQL[2][3][4][5] as a one byte representation of an integer). Better use integer and smallint, anyway, and avoid the (10) or (3) or (whatever) notation. And so far it's a nice documentation Yannick [1] http://en.wikipedia.org/wiki/SQL [2] http://dev.mysql.com/doc/refman/5.1/en/numeric-types.html [3] PostgreSQL - no tinyint http://www.postgresql.org/docs/7.4/interactive/datatype.html#DATATYPE-INT [4] Oracle - no tinyint http://download.oracle.com/docs/cd/B14117_01/server.101/b10759/sql_elements001.htm#i54335 [5] MSSQL - tinyint http://webcoder.info/reference/MSSQLDataTypes.html _______________________________________________ Dev mailing list Dev@lists.chamilo.org http://lists.chamilo.org/listinfo/dev
