diffdb

Usage:

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

Compare two databases, line by line.

This function is not exported.

Arguments ('*' denotes required arguments):

  • dbh1 => obj

    Alternative to specifying dsn1/user1/password1.

  • dbh2 => obj

    Alternative to specifying dsn2/user2/password2.

  • diff_command => str (default: "diff")

  • dsn1 => str

    DBI data source, e.g. "dbi:SQLite:dbname=/path/to/db1.db".

  • dsn2 => str

    DBI data source, e.g. "dbi:SQLite:dbname=/path/to/db1.db".

  • exclude_columns => array[str]

  • exclude_tables => array[str]

  • include_columns => array[str]

  • include_tables => array[str]

  • order_by => str

  • password1 => str

    You might want to specify this parameter in a configuration file instead of directly as command-line option.

  • password2 => str

    Will default to password1 if password1 is specified.

    You might want to specify this parameter in a configuration file instead of directly as command-line option.
