Hello Pavel,
I try to create operator + for varchar and integer with Oracle behave.
create or replace function sum(varchar, int)
returns int as $$ select $1::int + $2 $$ language sql;
create operator + (function = sum, leftarg = varchar, rightarg = int,
commutator = +);
create table
Hi
I try to create operator + for varchar and integer with Oracle behave.
create or replace function sum(varchar, int)
returns int as $$ select $1::int + $2 $$ language sql;
create operator + (function = sum, leftarg = varchar, rightarg = int,
commutator = +);
create table foo2(a varchar);
