--------------------------------------

Hi [~jamestaylor],
function POSITION's API is position(substring in string), which need "substring in string" as a parameter.
In order to detect "substring in string" as a parameter, I think we should add one more parser node, and add it to compiling sql phase.

So how to implement this? Please point out some related class which are related to compiling sql and generating syntax tree.

function SUBSTRING and TRIM also need new parser nodes.

Thanks.
