You have a few choices:-
  • Embed a write-to-file command in your SQL
  • Redirect the output to a file.

The SQL write to file for mysql is documented here MySQL :: MySQL 5.7 Reference Manual :: 13.2.9.1 SELECT ... INTO Syntax The gotcha is that the file is local to the database, so if you are connecting to a remote database, it doesn't write the file to your local client disk, so that may not be acceptable. You seem to be connecting to the localhost, so it should work just fine.

In the latter, option would be to add > /path/to/my_output_file into your script. You would put it in place to capture the output from the MYSQL command, although I would have expected this to be actually a mysql command.

You should get away with this:-
Code:
MYSQL -u$MASTER_DB_USER -p$MASTER_DB_PASSWD -P$MASTER_DB_PORT -h$MASTER_DB_HOST -D$MASTER_DB_NAME <<EOF > /path/to/my_output_file
$SQL_Query
EOF
echo "End of script"


I hope that this helps,
Robin

NAME
DBIx::Class::Storage::DBI::mysql - Storage::DBI class implementing MySQL specifics SYNOPSIS
Storage::DBI autodetects the underlying MySQL database, and re-blesses the $storage object into this class. my $schema = MyApp::Schema->connect( $dsn, $user, $pass, { on_connect_call => 'set_strict_mode' } ); DESCRIPTION
This class implements MySQL specific bits of DBIx::Class::Storage::DBI, like AutoIncrement column support and savepoints. Also it augments the SQL maker to support the MySQL-specific "STRAIGHT_JOIN" join type, which you can use by specifying "join_type => 'straight'" in the relationship attributes It also provides a one-stop on-connect macro "set_strict_mode" which sets session variables such that MySQL behaves more predictably as far as the SQL standard is concerned. STORAGE OPTIONS
set_strict_mode Enables session-wide strict options upon connecting. Equivalent to: ->connect ( ... , { on_connect_do => [ q|SET SQL_MODE = CONCAT('ANSI,TRADITIONAL,ONLY_FULL_GROUP_BY,', @@sql_mode)|, q|SET SQL_AUTO_IS_NULL = 0|, ] }); AUTHORS
