Name

       sqitch-revert - Revert changes to a database

Synopsis

         sqitch [options] revert [<database>]
         sqitch [options] revert [<database>] <change>
         sqitch [options] revert [<database>] --to-change <change>

Description

       Revert changes to the database. Starting from the current deployment state, changes will
       be reverted in reverse the order of application. All changes will be reverted unless a
       change is specified, either via "--to" or with no option flag, in which case changes will
       be reverted back to that change.

       If the database has not been deployed to, or its state already matches the specified
       change, no changes will be made. If the change appears later in the plan than the
       currently-deployed state, an error will be returned, along with a suggestion to instead
       use sqitch-deploy.

       The "<database>" parameter specifies the database to which to connect, and may also be
       specified as the "--target" option. It can be target name, a URI, an engine name, or plan
       file path.

Options

       "-t"
       "--target"
           The target database to which to connect. This option can be either a URI or the name
           of a target in the configuration.

       "--to-change"
       "--change"
       "--to"
           Specify the reversion change. Defaults to reverting all changes. See sqitchchanges for
           the various ways in which changes can be specified.

       "-s"
       "--set"
           Set a variable name and value for use by the database engine client, if it supports
           variables. The format must be "name=value", e.g., "--set defuser='Homer Simpson'".
           Overrides any values loaded from the "deploy.variables" or "revert.variables"
           configurations.

       "--log-only"
           Log the changes as if they were reverted, but without actually running the revert
           scripts.

       "-y"
           Disable the prompt that normally asks whether or not to execute the revert.

Configuration Variables

       "[deploy.variables]"
       "[revert.variables]"
           A section defining database client variables. The "deploy.variables" configuration is
           read from the "deploy" command configuration, on the assumption that the values will
           generally be the same. If they're not, use "revert.variables" to override
           "deploy.variables".

           These variables are useful if your database engine supports variables in scripts, such
           as PostgreSQL's "psql" variables <http://www.postgresql.org/docs/current/static/app-
           psql.html#APP-PSQL-INTERPOLATION>, Vertica's "vsql" variables
           <http://my.vertica.com/docs/7.1.x/HTML/index.htm#Authoring/ProgrammersGuide/vsql/Variables.htm>,
           MySQL's user variables <http://dev.mysql.com/doc/refman/5.6/en/user-variables.html>,
           and SQL*Plus's "DEFINE" variables
           <http://docs.oracle.com/cd/B19306_01/server.102/b14357/ch12017.htm>.

       "[revert.no_prompt]"
           A boolean value indicating whether or not to disable the prompt before executing the
           revert. My be overridden by "-y".

       "[revert.prompt_accept]"
           A boolean value indicating whether default reply to the prompt before executing the
           revert should be "yes" or "no". Defaults to true, meaning to accept the revert.
