I am wondering if a very useful feature of some DB's is available in postgres For example in DB2 you can execute SQL from the command line (via terminal emulator) It will perform it entirely then display the results, but only one page at a time You can then page down and page up within the results (or scroll across) I notice that PSQL doesn't do this which makes large tables difficult to maintain Of course you could put a decent Where clause in but in the real world most people like to narrow things down to a certain point then scroll around a few hundred records looking for the data by hand. Currently this doesn't seem to be possible The only way I can think of doing this is to write a program in C (or use ODBC/JDBC) to perform the SQL then retrieve x records and display them and allows paging to be performed When paging down the current set would be cached so that page up's would be possible Doing this in VB would be easy and you could allow data to be editted to... NB Unfortunately MS Access is no good because it tries to load ALL the data in one go and you CANT get out of it!!! Anyone got any better ideas???
