Name
sqitch-revert - Revert changes to a database
Synopsis
sqitch revert [options] [<database>]
sqitch revert [options] [<database>] <change>
sqitch revert [options] [<database>] --to-change <change>
sqitch revert [options] [<database>] --modified
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.
Attention Git Users
If you're a git user thinking this is like "git revert", it's not. "sqitch revert" is more like time
travel. It takes your database back to the state it had just after applying the target change. It feels
like magic, but it's actually all the time you spent writing revert scripts that finally pays off.
Starting from the last change currently deployed, "sqitch revert" runs each revert script in turn until
the target change is reached and becomes the last change deployed.
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.
"-m"
"--modified"
Finds the change to revert onto based on modifications to deploy scripts. Reverts the change prior to
earliest change with a revised deploy script.
"-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
"configuration Variables".
"--log-only"
Log the changes as if they were reverted, but without actually running the revert scripts.
"--lock-timeout"
sqitch deploy --lock-timeout 600
Set the number of seconds for Sqitch to wait to get an exclusive advisory lock on the target
database, for engines that support such a lock. This lock prevents other instances of Sqitch from
deploying to the target at the same time, but prevents no other database activity. Defaults to 60.
"-y"
Disable the prompt that normally asks whether or not to execute the revert.
"--registry"
sqitch revert --registry registry
The name of the Sqitch registry schema or database in which sqitch stores its own data.
"--db-client"
"--client"
sqitch revert --client /usr/local/pgsql/bin/psql
Path to the command-line client for the database engine. Defaults to a client in the current path
named appropriately for the database engine.
"-d"
"--db-name"
sqitch revert --db-name widgets
sqitch revert -d bricolage
Name of the database. In general, targets and URIs are preferred, but this option can be used to
override the database name in a target.
"-u"
"--db-user"
"--db-username"
sqitch revert --db-username root
sqitch revert --db-user postgres
sqitch revert -u Mom
User name to use when connecting to the database. Does not apply to all engines. In general, targets
and URIs are preferred, but this option can be used to override the user name in a target.
"-h"
"--db-host"
sqitch revert --db-host db.example.com
sqitch revert -h appdb.example.net
Host name to use when connecting to the database. Does not apply to all engines. In general, targets
and URIs are preferred, but this option can be used to override the host name in a target.
"-p"
"--db-port"
sqitch revert --db-port 7654
sqitch revert -p 5431
Port number to connect to. Does not apply to all engines. In general, targets and URIs are preferred,
but this option can be used to override the port in a target.
"--plan-file"
"-f"
sqitch revert --plan-file my.plan
Path to the deployment plan file. Overrides target, engine, and core configuration values. Defaults
to $top_dir/sqitch.plan.
Configuration Variables
"[deploy.variables]"
"[revert.variables]"
A section defining database client variables. The "deploy.variables" configuration is read from the
"deploy" command configuration, on the assumption that the values will generally be the same on
revert. If they're not, use "revert.variables" to override "deploy.variables".
These variables are useful if your database engine supports variables in scripts, such as
PostgreSQL's "psql" variables <https://www.postgresql.org/docs/current/static/app-psql.html#APP-PSQL-
INTERPOLATION>, Vertica's "vsql" variables
<https://my.vertica.com/docs/7.1.x/HTML/index.htm#Authoring/ConnectingToHPVertica/vsql/Variables.htm>,
MySQL's user variables <https://dev.mysql.com/doc/refman/5.6/en/user-variables.html>, SQL*Plus's
"DEFINE" variables <https://docs.oracle.com/cd/B19306_01/server.102/b14357/ch12017.htm>, and
Snowflake's SnowSQL variables <https://docs.snowflake.com/en/user-guide/snowsql-use.html#using-
variables>.
May be overridden by "--set" or target and engine configuration. Variables are merged in the
following priority order:
"--set"
"target.$target.variables"
"engine.$engine.variables"
"revert.variables"
"deploy.variables"
"core.variables"
"revert.strict"
A boolean value indicating whether or not the change to revert to must be specified.
"[revert.no_prompt]"
A boolean value indicating whether or not to disable the prompt before executing the revert. May 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.
