changelogSync command marks all undeployed changes in your changelog as executed in your database.
changelogSync command is typically used when you want to baseline a new database environment.
An example use case for the
changelogSync command is when you have a DEV environment with a set of objects used only in DEV, and you want to use the same changelog to manage a new TEST environment.
The TEST environment does not have or need, those DEV-only objects. To avoid deploying the DEV-only objects, you run the
changelogSync command to mark those changes as executed in the DATABASECHANGELOG which tells Liquibase to treat these databases as equivalent.
You can also use the
changeLogSync command to mark a change as executed if the object associated with the change was created manually on the database. By marking the changeset as executed, it prevents the next Liquibase update from failing as it tries to create an object that already exists.
To run the
changelogSync command, type the following into your command line:
Liquibase --changelogFile=mychangelog.sql changelogSync
mychangelog.sql with the name of your changelog and ensure you have specified your JDBC database connection URL in your
changelogSync global attributes
||The root changelog||Required|
||The JDBC database connection URL||Required|
||The database username||Required|
||The database password||Required|
When successful, the changelogSync command produces the following output: Liquibase Pro 3.8.7 by Datical licensed to Liquibase Pro Customer until Tue Sep 22 19:00:00 CDT 2020 postgres@jdbc:postgresql://localhost:5432/MYDATABASE2 is up to date Liquibase command 'status' was executed successfully.
