##! General comments:
##!
##! The idea behind this expressions is to capture simple logic based (un)equalities that
##! are used to quickly test SQL Logic that always returns FALSE.

##! Prefix: captures the initial part that will be unmatched on the right hand side of the logical construct.

##!^ [\s'\"`()]*?\b([\d\w]+)\b[\s'\"`()]*?

##!+ i

##! These expressions try to match the logic using the negative operator,
##! so when the operator targets a false operation, the initial match
##! should *not* be present after the operator, effectively meaning TRUE.
##!
##! Examples:
##! '1' <= '2'
##! 'a' not like 'b'
##!
##! SQL Comparison Operators: !=, <=, >=, <>, <, >, !>, !<, ^
