Description
Need to have less than, greater than, and numeric equals operator support in the
pathquery language so that we can do spatial and othe rimportant queries.
Updated by Jivka Bojilova over 21 years ago
DONE
Included new terms in pathquery.dtd for searchmode:
equals (former "matches-exactly")
isnot-equal
less-than
greater-than
less-than-equals
greater-than-equals
added support for them in QuerySpecification. Tested in Oracle.
For = and != operators: ='1' and =1 (!='1' and !=1) work in the same way for
numeric operands thus ='operand' is used only.
For >, >=, <, <= check for numeric operand is added like:
if (operand is Number)
operator operand
else //character operand
operator 'operand'
