update

The update Change Type updates the data in an existing table.

Uses

You can typically use the update Change Type when you want to update a table in your changelog file and then deploy this update to your database. It can include columns and another values listed in this documentation.

Running the update Change Type

To run this Change Type, follow these steps:

  1. Add the Change Type to your changeset, as shown in the examples on this page.
  2. Specify any required attributes. Use the table on this page to see which ones your database requires.
  3. Deploy your changeset by running the update command:
    4. liquibase update

Now, you should see an updated table.

Note: You can use the update Change Type in combination with loadData and loadUpdateData Change Types.

Differs from value by returning the value of the function or column you specify instead of the name of the function/column as a string. Can also perform operations on the returned value.
