Filter and Expression Languages
 
 
 

This chapter discusses the use of filters and filter expressions. You can use filters and expressions to specify to an FDO provider how to identify a subset of the objects in a data store.

For more information and implementation details about the expression functions signatures, the RDBMS-specific built-in support for some of the functions, and the provider-specific support, see the appendix Expression Functions.
