# ==== Purpose ====
#
# Execute a statement and write the result to a file. This is useful
# if the output needs more advanced parsing than can be done by
# mysqltest commands.
#
# ==== Usage ====
#
# --let $statement= <STATEMENT>
# --let $output_file= {<FILE>|GENERATE}
# [--let $server_number= <NUMBER>]
# [--let $dont_print_statement= 1]
# --source include/write_result_to_file.inc
#
# Parameters:
# $statement
# The statement to execute.
#
# $server_number
# 1 for the master, 2 for the slave, 3 for next server, etc.
# If omitted, uses current connection.
#
# $output_file
# Name of file to write. If omitted, generates a new filename and
# stores the name both in the mysqltest variable $output_file and
# in the environment variable $OUTPUT_FILE.
#
# $dont_print_statement
# By default, the statement is echoed to the result log. If the
# statement contains non-deterministic output, set this variable
# to suppress it.
