derby database source code.good for you.

# ANY CHANGE MADE TO THIS FILE SHOULD PROBABLY ALSO BE MADE TO
# $WS/java/com/ibm/db2j/impl/Connectivity/JDBC/Local/metadata.properties
#
# This file is used by DRDA to determine values for methods
# from java.sql.DatabaseMetadata.  We try to emulate the SYSIBM
# stored procedures that are used in DB2 for the MetaData.  
# These are called from
# $WS/drda/jcc/src/com/ibm/db2/jcc/am/DatabaseMetaData
#
# JDBC driver will take the value and perform
# a statement.execute() request on it, returning the result set or using the
# result set to produce an answer of the required type and format for the
# DatabaseMetadata method.  If the query has AS clauses in its select list items,
# you can be pretty sure that the JDBC driver was looking for a result set,
# because it specifies what it wants the column names to be.
#
#
# Note that property values can span multiple lines, by ending the line with a \
#
# Note: be sure to always enter SQL keywords in CAPS, this is both
# for convention, and because of the way the parser uppercases
# things (so it is purportedly faster that way).
#
# REMIND: using SYSALIASES; need to deal with ProcedureColumns still.
# there are no procedures or metadata about them in our system yet.
# NOTE: the order by would include PROCEDURE_SCHEM, but it is always ''
# so we leave it out.
#
# PROCEDURE_TYPE is always procedureResultUnknown as it could map to
# multiple methods, some of which could return a value and some not.
#
# Now that we have java Stored procedures we can more easily implement these calls
# Thus, $WS/java/com/ibm/db2j/catalog/SystemProcedures now calls the LocalDatabaseMetadata methods.
