Hello

I have difficulties to obtain bison-3.6.2
#apk search bison --update-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/main
reports as expected
bison-doc-3.6.2-r0
bison-3.6.2-r0

but
#apk add bison --update-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/main
doesn't install anything (bison 3.0.5 is already installed)
fetch http://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.9/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.9/community/x86_64/APKINDEX.tar.gz
OK: 248 MiB in 86 packages
and 
# bison --version
bison (GNU Bison) 3.0.5

and
#apk add bison-3.6.2 --update-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/main
is missing (idem for bison-3.6.2-r0)
fetch http://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.9/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.9/community/x86_64/APKINDEX.tar.gz
ERROR: unsatisfiable constraints:
  bison-3.6.2 (missing):
    required by: world[bison-3.6.2]

Thank you for your help

Alpine doesn't support mixing release branches and edge due to differences in ABI and other things.
Either switch to edge or install alpine-sdk and build updated bison locally with abuild.
