Aan iedere ResultSet is ook Meta Data, of bijkomende informatie, gekoppeld. Dit kan gaan van de naam van dee kolommen tot het aantal kolommen, de datatypen, …
Hierdoor kunnen we gebruik maken van welke databank dan ook en de gegevens op te vragen via de code. Dit zorgt voor een flexibel systeem.
Je kan dit opvragen op het ResultSet object met de methode getMetaData(). Dit zal dan een ResultSetMetaData object terug geven.
