Detailed Description

A query encoder for binary operator expressions.

You can use a special notation in order to translate the function arguments to a specific dialect convetion.

You can write an expression like: ($1 from $2 for $3) in order to write a function with arguments in differnt positions. The $n numbers will be used to map the arguments to its right place.
