--quick (-q)

Overview

This is a command-line option for the mariadb & mysql commands.

Don't cache result, print it row by row. This may slow down the server if the output is suspended. Doesn't use history file.

USAGE

DETAILS

The --quick command-line option can be used to reduce memory usage for queries that return large result-sets.

By default, when mariadb client retrieves a result-set, it retrieves the entire result-set and buffers it in memory before displaying it. When the --quick command-line option is specified, it retrieves results from the server a row at a time instead, which can reduce memory usage.
