c# - Apparent ODBC recordset size limit -


platform windows 10.

i doing stress testing on 32 bit app using components purport intelligent caching large data sets built around adodb operations. have 64 bit postgresql v9.6 server installed using default user inputs, , i'm using psqlodbc 32 bit odbc driver offered installed during server install, , referencing driver through standard odbc connection set through 32 bit odbc control panel applet.

i loaded database table 5 million records testing. worked expected, know odbc connection , write new rows part of api working correctly.

the table has bigint primary key (bigserial actually) , text field contains key value formatted out take space. rows can seen , browsed in pgadmin4 app installs server.

in app, open recordset query:

select * mytable;

this takes 20 sec server process , control returned app ui. expected recordset count of 5000000. instead, recordset 84796 records in it.

can please explain might going on here, , how work around it, if possible? thanks.

need more info, ask.

cheers
