projection: In SQL, a high fallutin' word for listing the columns you want included in the results of a query, i.e. the list of fields in a SELECT statement. In dbAnywhere, a Projection object is an non-visible object your program can interact to get or set the value of some particular column in an SQL table. For example, if you wanted a dummy object that did not display on the screen, but that gave you program access to the database values in a column, you would use a Projection object that implements the ProjBinder interface. I think you would still need a ProjBinder object to glue it to the RelationView object. dbAnywhere, ProjBinder
