> The topic "JDBC escape syntax for fn keyword" 
> (http://db.apache.org/derby/docs/dev/ref/rrefjdbc88908.html) does not include 
> all the functions listed in Appendix C of the JDBC specification that Derby 
> supports.
> The following numeric functions, listed in Section C.1, are implemented in 
> Derby but not listed in this topic:
> COT(float)
> RAND(integer)
> SIGN(number)
> Three numeric functions listed in Section C.1 are not yet implemented in 
> Derby; they should be added to this topic when they are. (See DERBY-3893.)
> A number of the string functions listed in Section C.2 are not implemented in 
> Derby. Of the ones that are, the following are not listed in the JDBC escape 
> syntax topic:
> LCASE(string)
> LENGTH(string)
> LTRIM(string)
> RTRIM(string)
> UCASE(string)
> Some of the time and date functions listed in Section C.3 are not implemented 
> in Derby. Of the ones that are, only two (TIMESTAMPADD and TIMESTAMPDIFF) are 
> listed in the JDBC escape syntax topic. The following should be added:
> CURDATE()
> CURTIME()
> HOUR(time)
> MINUTE(time)
> MONTH(date)
> SECOND(time)
> YEAR(date)
> Two of the three system functions listed in Section C.4 are not implemented 
> in Derby. The one that is, USER(), is not listed in the JDBC escape syntax 
> topic.
> The functions should be listed in groups by type of function, and the fonts 
> should conform with Derby documentation style.
