Reference Manual: supported functions should be listed in JDBC escape syntax
topic
----------------------------------------------------------------------------------
Key: DERBY-3894
URL: https://issues.apache.org/jira/browse/DERBY-3894
Project: Derby
Issue Type: Bug
Components: Documentation
Affects Versions: 10.4.2.0
Reporter: Kim Haase
Assignee: Kim Haase
Priority: Minor
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.
