CREATE TYPE

I want to create a data type that have tow arguments in the defenition,
like the varchar type:
create table mytmp(name varchar(10));

I like to do it like this:
create table mytmp(name myvarchar(10,"en_US"));

whow can it be done by "CREATE TYPE"
I want to implement the internal functions (compare, ...).
I faunded the documentation but I can't see any thing that help me to
create a type same as varchar( with argument)

Notice: I don't mean using "CREATE TYPE myvarchar AS( lenght integer,
collate char(10))

Thanks

you can't unless you modify the parser.
It has special cases to support varchar (and numeric) syntax.

Re: CREATE TYPE

Hello

i note something related to this discussion

> create table mytmp(name myvarchar(10,"en_US"));

i meant that "en_US" is a locale name, then it means natural language and
also character encoding -- those both things are not a matter of SQL-TYPE at
all. It is wrong to represent application specific data in SQL-TYPE itself.
