NAME

sqlselect_to_db - convert MySQL or MariaDB selected tables to fsdb

SYNOPSIS

sqlselect_to_db <source.sqlselect_table >dest.fsdb

DESCRIPTION

Converts a MySQL or MariaDB tables to Fsdb format.

The input is not fsdb. The first non-box row is taken to be the names of the columns.

The output is two-space-separated fsdb. (Someday more general field separators should be supported.)

This module also supports the standard fsdb options:

-d

Enable debugging output.

-i or --input InputSource

Read from InputSource, typically a file name, or - for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

-o or --output OutputDestination

Write to OutputDestination, typically a file name, or - for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

--autorun or --noautorun

By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The --(no)autorun option controls that behavior within Perl.
