版次注意事項
- DB2 Version 7 products on Windows 32-bit platforms support user IDs that
are up to 30 characters long. However, because of native support of Windows
NT and Windows 2000, the practical limit for user ID is 20 characters.
- DB2 Version 7 supports non-Windows 32-bit clients connecting to Windows
NT and Windows 2000 with user IDs longer than 8 characters when user ID and
password are being specified explicitly. This excludes connections using Client
or DCE authentication.
- DCE authentication on all platforms continues to have the 8-character
user ID limit.
- The authid returned in the SQLCA from a successful CONNECT or ATTACH is
truncated to 8 characters. The SQLWARN fields contain warnings when truncation
occurs. For more information, refer to the description of the CONNECT statement
in the SQL Reference.
- The authid returned by the command line processor (CLP) from a successful
CONNECT or ATTACH is truncated to 8 characters. An ellipsis (...) is appended
to the authid to indicate truncation.
- DB2 Version 7 supports schema names with length up to 30 bytes, with the
following exceptions:
- Tables with schema names longer than 18 bytes cannot be replicated.
- User defined types (UDTs) cannot have schema names longer than 8 bytes.
