Hi all, I've just written my first pl/pgsql function (code included below for
you to pull apart).
It takes an int4 mid (e.g. 15) and then using a select pulls out the team
number (e.g. 'NE/012' and a unit number (e.g. 2) and returns the full unit
number NE/012-02.
I now want to write the reverse function, where I can enter 'NE/012-02' and
get back the mid 15. The bit I'm stuck on is now I split the team part from
the member part so that I can build the select statement.
TIA Gary
__BEGIN__
CREATE FUNCTION getunitno(int4) RETURNS varchar AS '
DECLARE
mid ALIAS FOR $1;
results RECORD;
BEGIN
select into results t.tnumber as tnumber, m.mnumber as mnumber
from teams t, members m
where t.tid = m.mteam and m.mid = mid;
if results.mnumber < 10 then
return results.tnumber || ''-0'' || results.mnumber;
else
return results.tnumber || ''-'' || results.mnumber;
end if;
END;
' LANGUAGE 'plpgsql';
__END__
