Hello.
Dynamically created PostgreSQL table (size is not known in advance) is queried by TSQLQuery and presented in RxDBGrid for reading, editing, searching, filtering and exporting to spreadsheet or plain text files. The dataset must be editable and forward/backward browseable, readonly or unidirectional is not an option!
When underlying table is big, memory (16 GB) is completely consumed.
I need recommendations about alternative approaches - instead of TSQLQuery I need some other way to browse/edit underlying PostgreSQL table that will not load all rows in memory at once, but in chunks while browsing.
Is ZTable (from ZeosDBO) a viable alternative?
Is there any other dataset components, instead of TSQLQuery, which can browse underlying PostgreSQL table (for editing), in small chunks, not overconsuming RAM?
