[fdo-internals] MOTION: RFC29: Redefining Expression FunctionEXTRACT

Fine by me, though I still find the naming of the function a bit
unintuitive J

Hi All,

 

I would like to motion that RFC 29: "Redefining Expression Function
EXTRACT" be adopted.

Hi Jason,

 

The proposed solution is close to the signature we currently support for
the expression function Extract. It also is in-line with other functions
where we accept an identifier from an enumeration to avoid having
multiple functions that just differ in the kind of information it
returns. But if the consensus in this discussion is to have functions
for each of the date/time properties, then the RFC could be adopted.

 

Thanks

 

  Thomas

Interesting...

 

Would there be any interest in superseding this function with individual
YEAR(), MONTH(), DAY(), etc functions?  This would be easier to parse in
the expression definition, and the user wouldn't have to think about the
return type (YEAR() always returns int, SECONDS() always returns double,
etc.)

Hi,

 

I posted a new RFC (http://trac.osgeo.org/fdo/wiki/FDORfc29) related to
a usability issue of the expression function EXTRACT. The proposed
solution will redefine this expression function for easier use. Please
review the RFC and let me know of any questions/issues/suggestions you
may have. 

 

Thanks

 

  Thomas
