The column definitions from the view definition are easy. You can find them in DBC.Columns under where the TableName = <View Name> and DatabaseName = <View Database Name>. However, making taking the next step to get back to the source table is almost impossible. You could do some experiments of comparing what DBC.Columns (or DBC.TVFields) shows for the view column and base table. From there you might be able to draw some conclusions as to what your being asked to deliver. Let me know if I misunderstood your question. Hello Prashant,

I hae no words to describe my ecstacy when i saw ur website. I am a budding Teradata developer, and am working as a Database Analyst at a Indian company. Currently, i am struggling to develop a Field Catalog for a insurance organisation, who is our client. Now, what they have given me is a schema, which has some views( that are created from base tables which reside in theproduction db). Now they have asked me to create a catalog, which should aid analysts to make business models. This catalaog, according to them, should contain definitions of various variables from the schema. Now, i want to ask you, how shud i begin doing it. First of al, i want to write a macro, which can use dbc tables, to tell me what are the base tables for the views in that particular schema. can it be done?( i want to kindda automate it, since it will be used on other schemas as well, and it should be noted here, that each schema holds around 60 views.) Thanks. I hope yo will reply and help me clear my doubts. And please don't mind if i keep coming up wid bother-ful questions(wow, if for nothing, i devised a new slang!) Bye and take care.
