support collate postfix operator
support escape and uescape as postfix operators
change the collate support in substring and trim which isn't a special
case in the sql 2003 grammar anymore but just a normal collate postfix
operator, the old code had the collation name as a string, but the
new style is as an identifier
fix number literals to accept upper case E
implement multi part string literals
fix tests for string literals, typed literals, boolean literals and
number literals in the sql 2003 tests
change the parser to not attempt to parse the elements following
'from' unless there is a actual 'from'
improve the symbol parser to try to deal with issues when symbols are
next to eachother with no intervening whitespaces
improve number literal parsing to fail if there are trailing letters
or digits which aren't part of the number and aren't separated with
whitespace
add some code to start analysing the quality of parse error messages
partially add buildExprParser hack to deal with some nested prefix and
postfix unary operators
add new file which starts going through the sql2003 grammar to try to
create lots of examples for comprehensive testing of sql2003
support.
replace the lexers with lexers from the tutorial project
