	addIdentifierQuotes ( $s)
	Escape a SQL identifier (e.g.
	anyChar ()

	buildComparison (string $op, array $conds)
	Build a condition comparing multiple values, for use with indexes that cover multiple fields, common when e.g.
	buildConcat ( $stringList)
	Build a concatenation list to feed into a SQL query. Parameters string[] $stringList Raw SQL expression list; caller is responsible for escaping Returns string
