Dear all,
I sent this message� a few days ago without response so I post it again
in case someone may help me.
I use PostgreSQL 6.5 and create a function� tmod(bpchar) written in C.
When I try to create index using the function I have the
following problem.
------ 1-------
mydb=> CREATE INDEX vi_id ON village (vi_name bpchar_ops,vi_id
bpchar_ops);
CREATE
this works find.
------ 2 -------
mydb=> CREATE INDEX tmodvi_name ON village (TMOD(vi_name) bpchar_ops);
CREATE
this also works fine.
but when I try
------ 3 -------
mydb=> CREATE INDEX xxvi_name ON village (TMOD(vi_name) bpchar_ops,vi_id
bpchar_ops);
ERROR:� parser: parse error at or near ","
What wrong with this?� Can I create index� multiple column index with
user-defined function??
