# ==== 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.
