Thanks a lot. The MAL I have still doesn't make sense, but I will work on it.

pattern bind(mvc:int, schema:str, table:str, column:str, access:int ):bat[:oid,:any_1] address mvc_bind_wrap comment "Bind the 'schema.table.column' BAT with access kind: 0 - base table 1 - inserts
2 - updates";
What do you mean by access kind here.
Data of each column are stored in three BATs. You can only bind to one BAT at a time. The value of 'access' determines to which BAT you want to bind. RDONLY (==0): the already persistently stored column data; RD_INS (==1): all data that have been inserted, but not yet committed; RD_UPDATE (==2): I think this one should contain all data that have been delete, but not yet committed. But I'm not completely sure, since there is also something called delta-BAT (dbat), which has something to do with updates... Regards, Jennie
Appreciate any help.
