Note: YAML and JSON changelogs using the column tag must nest it within a columns tag.

For each row, Liquibase uses the primary key to determine whether the record exists: If the record exists, Liquibase checks whether the database matches the CSV, and alters the table with 3 I need to convert a MySQL INSERT IGNORE INTO statement to a changeSet in liquibase and I prefer not to insert the statement directly in the changeSet. Learn how to use preconditions in Liquibase to optimize and control database changesets effectively. I came up this: If the index does not exist, the script should skip the drop index condition and proceed to create the new index. If in this table there is no entry for that primaryKey, 2 But I want the check to run only if the table exists, since a new install of the system would not have the table since the hibernate mapping objects no longer exist.

After running all the changes in the changesets, Liquibase inserts a new Liquibase uses these fields to track what changes have been run and what has not. Some of my Liquibase We are using liquibase formatted SQL (and need to stay in this format for the time being) and it has been going well, but I just encountered an issue that I cannot figure out how to get around.
