Where can I find the ANSI SQL 2003 specification for
INFORMATION_SCHEMA?
Unfortunately, the official specifications are not freely
available. (ANSI makes them available for purchase.) However,
there are books available, such as SQL-99 Complete,
Really by Peter Gulutzan and Trudy Pelzer, that
provide a comprehensive overview of the standard, including
INFORMATION_SCHEMA.
A.7.4.
What is the difference between the Oracle Data Dictionary and
MySQL INFORMATION_SCHEMA?
Both Oracle and MySQL provide metadata in tables. However,
Oracle and MySQL use different table names and column names. The
MySQL implementation is more similar to those found in DB2 and
SQL Server, which also support
INFORMATION_SCHEMA as defined in the SQL
standard.
A.7.5.
Can I add to or otherwise modify the tables found in the
INFORMATION_SCHEMA database?
No. Since applications may rely on a certain standard structure,
this should not be modified. For this reason, we
cannot support bugs or other issues which result from modifying
INFORMATION_SCHEMA tables or data.
