Narrative:
No deviation from clrnces; however; ATC reassigned our runway from runway 25L to runway 24R approximately 10 miles northeast of civet. When PNF attempted to reprogram FMC transition; intersection coxeb did not appear in database which led to confusion as to whether we had the correct routing programmed. This resulted in both of us getting behind the aircraft and having to abandon the RNAV STAR and go raw data with ATC's concurrence. Subsequent examination found that neither coxeb nor ekecu waypoints are in our database. Databases should exactly reflect the published charts to prevent such confusion.
