Bigtop::Backend::SQL::MySQL - backend to generate sql for MySQL database creation

If your bigtop file looks like this:

    config {
        SQL  MySQL {}
    }
    app App::Name {
    }

and there are table and/or sequence blocks in the app block, this module will make docs/schema.mysql (relative to the build_dir) when you type:

    bigtop app.bigtop SQL

or

    bigtop app.bigtop all

You can feed that file directly to psql, once you have created a database. That is type:

    mysql -u user -p
    > create database dbnmae;
    >
    quit
    mysql -u user -p dbname < docs/schema.mysql

This is a Bigtop backend which generates SQL MySQL can understand.

This module defines no keywords. Look in Bigtop::SQL for a list of the keywords you can use in table and sequence blocks.

Note that MySQL does not support sequences. Trying to use them with this backend will be fatal.

This module does provide a couple of bits of shorthand (some aren't so short) for the arguments of the is field statement.

    field id {
        is int4, primary_key, auto;
    }

This translates into:

    id MEDIUMINT PRIMARY KEY AUTO_INCREMENT

You can also type 'assign_by_sequence' instead of 'auto'. That might aid understanding, if you can type it correctly.

Note that using 'primary_key' instead of the literal 'PRIMARY KEY' is important. It tells the SQL and the Model back ends that this is the primary key.

To keep podcoverage tests happy.

backend_block_keywords

Tells tentmaker that I understand these config section backend block keywords:

    no_gen
    template

what_do_you_make

Tells tentmaker what this module makes. Summary: docs/schema.sqlite.

gen_SQL

Called by Bigtop::Parser to get me to do my thing.

setup_template

Called by Bigtop::Parser so the user can substitute an alternate template for the hard coded one here.
