1.20.1 Problem

Query output zooms off the top of your screen before you can see it.

1.20.2 Solution

Tell mysql to display output a page at a time, or run mysql in a window that allows scrollback.

1.20.3 Discussion

If a query produces many lines of output, normally they just scroll right off the top of the screen. To prevent this, tell mysql to present output a page at a time by specifying the --pager option. --pager=program tells mysql to use a specific program as your pag

The --pager option is not available under Windows.

% mysql --pager=/usr/bin/less

--pager by itself tells mysql to use your default pager, as specified in your PAGER environment variable:

% mysql --pager

If your PAGER variable isn't set, you must either define it or use the first form of the command to specify a pager program explicitly. 

Within a mysql session, you can turn paging on and off using \P and \n. \P without an argument enables paging using the program specified in your PAGER variable. \P with an argument enables paging using the argument as the name of the paging program:

mysql> \P
PAGER set to /bin/more
mysql> \P /usr/bin/less
PAGER set to /usr/bin/less
mysql> \n
PAGER set to stdout

Output paging was introduced in MySQL 3.23.28.

Another way to deal with long result sets is to use a terminal program that allows you to scroll back through previous output. Programs such as xterm for the X Window System, Terminal for Mac OS X, MacSSH or BetterTelnet for Mac OS, or Telnet for Windows allow you to set the number of output lines saved in the scrollback buffer. Under Windows NT, 2000, or XP, you can set up a DOS window that allows scrollback using the following procedure:

Now you should be able to launch the shortcut to get a scrollable DOS window that allows output produced by commands in that window to be retrieved by using the scrollbar.
