Enumeration Type Documentation

enum CoGaDB::SQL::ParseTree::ValueComparator

Operators supported by ComparisonPredicate.

It is not merely a typedef to CoGaDB::ValueComparator, so we can implement a broader set of operators on top of CoGaDB's very limited set.

Enumerator:

LESSER
LESSER_EQUAL
GREATER
GREATER_EQUAL
EQUAL
UNEQUAL

Function Documentation

static CoGaDB::Predicate CoGaDB::SQL::ParseTree::make_pred	(	const std::string &	column,
		const boost::any &	value,
		PredicateType	pred,
		CoGaDB::ValueComparator	comp
	)		[static]

Construct CoGaDB::Predicate.

It resolves boost::any to strings for ValueValuePredicates.

Parameters:

column	Name of column to compare
value	Value or name of column to compare with
pred	Predicate type
comp	Comparison operator

Returns:

a CoGaDB::Predicate
