" Column types
"
" This gets a bit ugly.  There are two different problems we have to
" deal with.
"
" The first problem is that some keywoards like 'float' can be used
" both with and without specifiers, i.e. 'float', 'float(1)' and
" 'float(@var)' are all valid.  We have to account for this and we
" also have to make sure that garbage like floatn or float_(1) is not
" highlighted.
"
" The second problem is that some of these keywords are included in
" function names.  For instance, year() is part of the name of the
" dayofyear() function, and the dec keyword (no parenthesis) is part of
" the name of the decode() function.

" General Functions
"
" I'm leery of just defining keywords for functions, since according to the MySQL manual:
"
"     Function names do not clash with table or column names. For example, ABS is a
"     valid column name. The only restriction is that for a function call, no spaces
"     are allowed between the function name and the `(' that follows it.
"
" This means that if I want to highlight function names properly, I have to use a
" region to define them, not just a keyword.  This will probably cause the syntax file
" to load more slowly, but at least it will be 'correct'.
