# At this time, no easily-parsed, definitive list of data types
# has been found in the MySQL source code or documentation. (The
# `sql/sql_yacc.yy` file is definitive but is difficult to parse.)
# Therefore these types are currently maintained manually.
#
# Some words in this list -- like "long", "national", "precision",
# and "varying" -- appear to only occur in combination with other
# data type keywords. Therefore they are included as separate words
# even though they do not naturally occur in syntax separately.
#
# This list is also used to strip data types out of the list of
# MySQL keywords, which is automatically updated later in the file.
