Thread: Paging through table one row at a ttime
I am running postgres 13 under CentOS 7. I have a need to be able to page through a table one row at a time, possibly usingpspg (or other tool) allowing me to move in either direction in the table one single row at a time. Ideally only thecolumns in the selected row should be visible, even better if there would be one column of that row per row in the terminalwindow but that would probably be wishing for too much. Is there any configuration of pspg that would allow me to do the above?

Aside from that most of us are simple sql users and data managers - we don’t go back andforth row by row all that often. Have you found the LIMIT and OFFSET features of SELECT statement? After that your inapplication space and not this forum perhaps >

Ideallyonly the columns in the selected row should be visible, even better if there would be one column of that row per
rowin the terminal window but that would probably be wishing for too much.

Yeah, I was confused by the question. I originally thought you were
asking about pagination, and I have several blog entries about that:

but it then sounded like you were looking for a terminal-level API,
which kind of sounded like pspg, which you are using, but something much
more sophisticated.

I have a need for a quick-and-dirty solution to paging through a postgresql table.pspg almost fits that need but could be even better. Using pspg I can either: (1) view one table row in each pspg terminalwindow row using the pspg flag to shorten columns, or (2) list as much of the table row in the pspg terminal windowas fits. Depending on the size of the row, this could mean less than one table row or more than one table row. To make it easier to view individual table rows in eg. pspg I would like to view exactly one table row, not more, and ideallyeach column of that table row would use individual pspg terminal rows. I hope that makes it clearer. Hoping this might be possible, either using pspg or other similar software. I am not writingany application code.

I would ask the pspg author on something that specific. -- Bruce Momjian <bruce@momjian.us> https://momjian.us EDB https://enterprisedb.com Indecision is a decision. Inaction is an action.
