Hello list,
The following patch implements cursor calling with named parameters in
addition to the standard positional argument lists.
c1 cursor (param1 int, param2 int) for select * from rc_test where a >
param1 and b > param2;
open c1($1, $2); -- this is currently possible
open c1(param2 := $2, param1 := $1); -- this is the new feature
Especially for cursors with a lot of arguments, this increases
readability of code. This was discussed previously in
http://archives.postgresql.org/pgsql-hackers/2010-09/msg01433.php. We
actually made two patches: one with => and then one with := notation.
Attached is the patch with := notation.
Is it ok to add it to the next commitfest?
regards,
Yeb Havinga, Willem Dijkstra
