Hello, I'm trying to generate a table with information on columns from a temporary view that simply selects a subset of columns from a persistent view in a given schema. The persistent view joins a number of tables with columns that may or may not have a description entered. I need a table with a list of columns from the temporary view, and the matching descriptions from the underlying persistent view.
Here's my attempt at listing the temporary view's columns and respective descriptions: SELECT cols.ordinal_position, cols.column_name, col_description(cl.oid, cols.ordinal_position::INT) FROM pg_class cl, information_schema.columns cols WHERE cols.table_catalog='dbname' AND cols.table_schema='some_schema' AND cols.table_name = 'persistent_view' AND cols.table_name = cl.relname ORDER BY cols.ordinal_position::INT; The problem, of course, is that it lists columns from the persistent view, instead of the subset of them in the temporary view. Is there a better way to do that? Hopefully this makes sense. Thanks, -- Seb
