" The SQL reserved words, defined as keywords.
" These were pulled from the following SQL reference:
"     http://help.sap.com/hana/hana_sql_en.pdf
" An easy approach is to copy all text from the PDF
" into a Vim buffer.  The keywords are in UPPER case,
" so you can run the following commands to be left with
" mainly the UPPER case words:
"   1.  Delete all words that do not begin with a Capital
"       %s/\(\<[^A-Z]\w*\>\)//g
"   2.  Remove all words where the 2nd letter is not a Capital
"       %s/\(\<[A-Z][^A-Z]\w*\>\)//g
"   3.  Remove all non-word (or space) characters
"       %s/[^0-9A-Za-z_ ]*//g
"   4.  Remove some known words
"       %s/\<\(SAP\|HANA\|OK\|AG\|IBM\|DB2\|AIX\|POWER\d\+\|UNIX\)\>//g
"   5.  Remove blank lines and trailing spaces
"       %s/\s\+$//g
"       %s/^\s\+//g
"       %s/^$\n//g
"   6.  Convert spaces to newlines remove single character
"       %s/[ ]\+/\r/g
"       %g/^\w$/d
"   7.  Sort and remove duplicates
"       :sort
"       :Uniq
"   8.  Use the WhatsMissing plugin against the sqlhana.vim file.
"   9.  Generated a file of all UPPER cased words which should not
"       be in the syntax file.  These items should be removed
"       from the list in step 7.  You can use WhatsNotMissing
"       between step 7 and this new file to weed out the words
"       we know are not syntax related.
"  10.  Use the WhatsMissingRemoveMatches to remove the words
"       from step 9.
