How to assemble all fields of (any) view into a string?
Hi. Using version 9.2. I'm trying to create a function that will take a record from any view and assemble it into a string, for export to another system. For example, this view:
> \d ebh_gain
View "public.ebh_gain"
Column | Type | Modifiers
-------------------+---------------+-----------
reporting_unit_id | character(3) |
case_id | character(10) |
event_date | character(8) |
ids_score | character(1) |
eds_score | character(1) |
sds_score | character(1) |
kc_auth_number | integer |
king_county_id | integer |
would get converted into a string with all the fields concatenated together, and space-padded to their full lengths.
My original idea was to do this in TCL by passing a record and a view name. The function would then look up the columns in the information_schema, and use that info to assemble and return the string. But it looks like TCL functions won't accept a record as an argument.
Any suggestions or advice most welcome. Thanks!
