A method and system for efficient allocation of memory in database retrieval employs a technique which allocates a memory portion of a first size which may or may not be smaller than a data item to be retrieved from the database (such as a column which may be of indeterminate length). In that circumstance, a first FETCH, for example, an SQL FETCH, is followed by a new syntactical instruction, a FETCH CONTINUE, until all of the data item is retrieved. The FETCH CONTINUE may involve allocating memory portions of similar or different sizes to accommodate additional fetched portions, and may involve varying numbers of fetches.
