Abstract
Provided are techniques for processing structured content within Large Object (LOB) data that is stored in a column of a database table. Structural metadata describing structures that each define a different format of the structured content is stored. A request for data in the database table is received. The structural metadata is used to create an empty result set with columns defined by at least two of the structures. For each row of data in the database table that includes LOB data, control data is used to identify one of the structures to be applied to the structured content within the LOB data stored in that row of data, and the structured content within the LOB data in that row of data is mapped to the columns in the result set based on the identified one of the structures. The result set is returned.
