I need help to create a sequential file with metadata

[abhishekmuradia]

I need help in knowing how to create a sequential file that will contain the metadata definition of all the columns , like column name , data type , length [/b]

[samba]

Yes, in sequential file we have columns and also import metadata

Hi Abhisek

You can manually create the table definition, or load the imported table definition. Please be specific about what exactly you want to know, so that we can help.

Do you need to export the metadata into a Sequential file?

[abhishekmuradia]

I need to know that like if i am giving the column name as item_id as an integer with the length of 20 and as a primary key , Then how can I display it into a sequential file like
column name length type key
Item_id 20 integer Yes

There is nothing directly within DataStage for doing this. You can generate this information using the Reporting Assistant or "hacking" the repository (perhaps with a DataStage job). You would need to know what fields within DS_METADATA contain the information you require; this metadata is not in the public domain.

Years ago I posted here a job (job control routine) for dumping a table definition in one of a number of formats; perhaps you could search for it and adapt that code.

Go out to IBM and download the Universe documentation. This will help you learn to write a program in Universe Basic that will parse the data from the underlying Universe files. I'm an old Pick programmer so it was not too difficult for me.

Greetings dhelsley. Old Pick programmers are always welcomed.

Ray's routine will extract the routines to XML. Why not export your routines as XML and hack that.

How, precisely, do you think this will help?

It is not the structure of the Repository, it is the structure of only some of the tables in doc_tool.mdb and presupposes that the poster is using the Reporting Assistant, which has been deprecated since version 6.0. Nor have you show which of the columns are key columns, so the join paths are not obvious even if this approach were to be used - but, then, why would one not be creating custom reports directly within doc_tool.mdb in this case?
