VERSION

This document describes version 0.002 of App::DiffDBSchemaUtils (from Perl distribution App-DiffDBSchemaUtils), released on 2018-12-03.

DESCRIPTION

This distribution includes several utilities:

FUNCTIONS

diff_db_schema

Usage:

diff_db_schema(%args) -> [status, msg, payload, meta]

Diff two database schemas.

This function is not exported.

Arguments ('*' denotes required arguments):

  • dsn1* => str

  • dsn2* => str

  • password1 => str

  • password2 => str

  • username1 => str

  • username2 => str

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

diff_mysql_schema

Usage:

diff_mysql_schema(%args) -> [status, msg, payload, meta]

Diff two MySQL database schemas.

Convenient thin wrapper for diff_db_schema, when you have two MySQL databases. Instead of having to specify two DSN's, you just specify two database names.

This function is not exported.

Arguments ('*' denotes required arguments):

  • db1* => str

    Name of the first MySQL database.

  • db2* => str

    Name of the second MySQL database.

  • password1 => str

  • password2 => str

  • username1 => str

  • username2 => str

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
