Hi All,

We require a script to extract all the objects in a schema and store it in a folder wise sequence.
ie.
On running the procedure/package the output would be like

<SchemaName>
<Tables>
<SchemaName>.<TableName1>
<SchemaName>.<TableName2>
<Views>
<Indexes>
and so on.

Basically every file would be the create script for that object.

Look at the DBMS_METADATA package. You are unlikely to get someone to just give you the full answer here. At OraFAQ we tend to look to you to do some/most of your own work, and offer support and advice when you get stuck. Much of the support and advice constitutes pointing you towards the appropriate documentation or towards useful keywords to search for.

Good luck. And remember, do ask questions when you run across problems but bear in mind you might not always get the exact answer back.

Look into DBMS_METADATA.GET_DDL

You can very nearly do
SELECT dbms_metadata.get_ddl(object_type,object_name)
FROM   user_objects
but some of the object types that DBMS_METADATA uses don't quite match with the ones from User_Objects.

How will we be able to extract this folderwise? We understand that using the dbms_metadata.get_ddl would allow us to get the objects source code but how do we create a single script which would run through the schema and store them in a directory listing mode?

Depending upon actual implementation either SPOOL or UTL_FILE can be used to create container SQL file.

you could also dump the data as XML and let the nesting of your queries do the "container" thing for you. But this is getting extravagant I think.

You might also wish to spend some money on a tool of see if you do not already have a tool available to you that will do this for you. Think TOAD, or any of the data modeling tool like ERSTUDIO or [gulp] Erwin.

Good luck, Kevin

Or you could just output objects into names that made it clear what soert of object they were, and move them by hand.

Is it me, or does doing actual work seem to be getting unfashionable these days?
