How to parse WHERE some.column LIKE "foo" + another.column +"bar"

[yuchaofan13]

The parser seems to run in to problems when parsing concatenation using +, raising the error 'Invalid expression / Unexpected token.'

Another problem I have is with concatenation using ||. e.g.

WHERE some.column LIKE "foo" || another.column || "bar"
