Introducing oraddlscript

A recent question on StackOverflow inspired me to write a utility called oraddlscript:

How to generate scripts for Oracle schema objects, such as tables, procedures, etc.

The answers directed me to the DBMS_METADATA package (9i documentation, 10g documentation). The function DBMS_METADATA.GET_DDL is the functional equivalent of the MSSQL SMO library, which prompted me to adapt my command-line utility SMOscript to Oracle databases. Voilà, oraddlscript.

oraddlscript 0.14.3584.16268 (c) by devio.at 2009

    list and script databases and database objects.

    usage: oraddlscript [options] [command]

    options: (leading '-' or '/')

    -s server       TNS name or host name or host:port
    -svc service    service name (if host name is provided)
    -o owner        owner name

    -u username     username (default: integrated authentication)
    -p password     password (if -u is missing, password for sa)

    -f filename     output to file
    -F directory    output to directory

    -A              current ANSI codepage
    -O              ASCII
    -T              Unicode
    -U              UTF8

    commands:

    l               list objects
    s               script object/s (using dbms_meta.get*ddl)
    -xml            use dbms_meta.get*xml

    list object owners on server (implied by -s)
    list objects in database (implied by -s -o)
    script all objects (implied by -s -o -F/-f)

The command-line arguments are consistent with SMOscript, except for -d (database) which has been replaced by -o (owner name).

The list of objects is retrieved by querying DBA_OBJECTS, ALL_OBJECTS and USER_OBJECTS depending on which of the catalog views is accessible by the user specified by -u.

The package also contains a function GET_XML which is used to retrieve the XML representation of a database object.

The functions of oraddlscript are:

• list usernames of object owners
• list objects of specific owner
• generate CREATE scripts of objects owned by specific user
• generate XML files representing objects owned by specific user
• generate one file per object or single file for all objects

Of course, logging and batch operations work just as previously described for SMOscript.
