Questions and Answers
23.7.1:
Where can I find documentation for the MySQL
INFORMATION_SCHEMA
database?
See Chapter 20, INFORMATION_SCHEMA
Tables
23.7.2:
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.
23.7.3:
Is there a discussion forum for
INFORMATION_SCHEMA
?
See http://forums.mysql.com/list.php?101.
23.7.4:
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
— which give a comprehensive overview of the standard,
including INFORMATION_SCHEMA
.
23.7.5:
What is the difference between the Oracle Data Dictionary and
MySQL's INFORMATION_SCHEMA
?
Both Oracle and MySQL provide metadata in tables. However,
Oracle and MySQL use different table names and column names.
MySQL's implementation is more similar to those found in DB2 and
SQL Server, which also support
INFORMATION_SCHEMA
as defined in the SQL
standard.
