hi matt, that's what i figured. so how about this idea: while the hard table associated with the dataset study.weights will not have a consistent name in postgres, could you do some pseudo-SQL along the lines of: set @weight_tables = select tablename from pg_tables where schemaname='studydataset' WHERE tablename ilike '%_weights'; foreach @weight_tables --create a materialized view for this table --create some triggers that keep this view up to date the part i dont know about is whether you can write SQL where the table name in the FROM clause is actually a variable. |
