hi, fellow gurus

I am creating a procedure for creating user, and I wanted to know what are the rules or format that one should obey when creating the username and password.

e.g. username cannot start with number? maximum length??

any one have any ideas??

here is the article I found, which outlines some rules / format for the password:

many thx in advance
Andy

See the SQL Reference Guide - "CREATE USER":

"Specify the name of the user to be created. This name can contain only characters from your database character set and must follow the rules described in the section "Schema Object Naming Rules". Oracle recommends that the user name contain at least one single-byte character regardless of whether the database character set also contains multibyte characters."

"The following list of rules applies to both quoted and nonquoted identifiers unless otherwise indicated:

1. Names must be from 1 to 30 bytes long with these exceptions:

- Names of databases are limited to 8 bytes.

- Names of database links can be as long as 128 bytes.

2. Nonquoted identifiers cannot be Oracle Database reserved words. Quoted identifiers can be reserved words, although this is not recommended."

Best regards.
