            Flyway - normalising between "schema_version" / "flyway_schema_history" table names - "Found non-empty schema(s) "PUBLIC" but no schema history table"
            Asked 2021-Dec-26 at 15:55

            I've been using Flyway in my application, where each use has their own persistent H2 database.

            Flyway v5 changed the metadata table name from schema_version to flyway_schema_history, and could handle both - but with the caveat Flyway v6 would not do this.

            Due to the databases persisting, and Flyway being upgraded from v4 to v5, some users have a schema_version table, while others have a flyway_schema_history table.

            Obviously Flyway v6 will not work for the databases with a schema_version table.

            Initially I was blocked, but then discovered callbacks that allow SQL to be run at arbritrary points. So the obvious solution was a beforeMigrate.sql that renamed the schema_version table to flyway_schema_history.

            However when I try this, even though I can see from the debug logs the command is executed, I get the following erorr. I even get the error when I manually rename the table in the database outside of the callback functionality.



            Answered 2021-Dec-26 at 15:55

            I personally have never used Flyway's callbacks but please, be aware that, according to the library source code, the beforeMigrate callback will be run in DbMigrate after the schema history table existence is checked in the Flyway class, so try renaming the history table may not work.

            As a possible solution, you could try providing explicitly the table name for your databases, keeping the previous one, schema_version. For example:



            Flyway wildcard is not working in Spring Boot
            Asked 2021-Oct-19 at 16:09

            I get the following error:



            Answered 2021-Oct-19 at 16:09

            As Flyway's location support has grown to support wildcards, cloud storage, etc., Spring Boot's ability to accurately check the locations has decreased as described in this issue. As a result, support for location checking was deprecated in Spring Boot 2.5 and, after the deprecation period, it will be removed entirely. In the meantime, you can switch it off by setting spring.flyway.check-location to false.



            Error in FlyWay migration after State/BaselineMigration scripts based migration
            Asked 2021-Oct-11 at 08:29

            I tried the State/BaselineMigration feature with a trial key. FlyWay migration execute the script and move to the correct version properly. But all the migration runs on top of that is failing

            Start with S2__xxx.sql then it creates a row in schema table with version 2 and type "SQL_STATE_SCRIPT"

            When performing flyway migration again with or without more scripts such as V3__xxx.sql it always produce an error

            Exception in thread "main" org.flywaydb.core.api.exception.FlywayValidateException: Validate failed: Migrations have failed validation Detected applied migration not resolved locally: 2. If you removed this migration intentionally, run repair to mark the migration as deleted. Need more flexibility with validation rules? Learn more:

            setting ignore missing flag or pattern doesn't help as well. Repair will solve only if there is a file with V2_xxx.sql

            I tried with 7.x and 8.x versions with java and 8.x with command line. all seems to have this issue.

            Is there anyway to solve this or i am violating the intended usage?

            My intension is we have existing setup with many versioned scripts lets say 10. When going to perform a fresh installation go with a S10__ instead of multiple versions but we should able to migrate future versioned scripts in ci/cd pipeline. With this issue that can not be done

            EDIT - This is fixed with 8.0.0 version



            Answered 2021-Oct-06 at 09:00

            We believe this is a bug, and a fix will go into the next v8 beta.



            Problem validating state of database before commit of version
            Asked 2021-Sep-01 at 05:58

            I'm playing around with Flyway and amongst other things, I would like to verify certain things in the database before committing the version. As an example, I would like the following migration to fail:



            Answered 2021-Sep-01 at 05:58

            afterEachMigrate actually works that way. The trick is that the commit of the version is a separate transaction, which waits for afterEachMigrate to finish.



            Is there a way to check if there is a pending migrate before running the actual migration with the flyway cli?
            Asked 2021-Aug-18 at 08:18

            I want to be able to run a command and determine if there is a pending migration. This is going to be scripted so the best thing would be a command that returns easy to parse output.

            The only command I could find for this is info but the output stinks. I want to confirm if there is a way to get parsable output.

            For example this command:



            Answered 2021-Aug-18 at 08:18

            You can use the -outputType=json command line argument, and then parse the output.



            flyway schema history table name
            Asked 2021-Jun-29 at 10:13

            We've been using flyway for schema migrations, versions 4.x/5.x - the table is named schema_version. Now we are looking to move to latest version, 7.x. I've seen some information that states the new table name has changed to flyway_schema_history, but then I just saw this where the table name looks to be named flyway_history_schema (

            Can anyone who uses flyway confirm the schema history table name?

            Thanks, Scott



            Answered 2021-Jun-29 at 10:13

            The default name for the table is indeed flyway_schema_history

            The part of the documentation you linked to is referring to the situation when Flyway is not allowed to create new schemas by its configuration, and you need to manually create a schema for that table to live in. "flyway_history_schema" is a suggested name for the schema, not the table.



            Does Flyway Community version support Oracle 19.7?
            Asked 2021-Mar-08 at 10:15

            Does flyway community version support Oracle 19c? From this URL:, it is up to 19.3. My oracle database is 19.7. I am not very familiar with oracle database versions.

            Any version support oracle 19.7 at all?




            Answered 2021-Mar-08 at 10:15

            Assuming no breaking changes have appeared in Oracle 19.7, then yes, we just have not formally tested it yet. If you try, you will get a warning to this effect in the log but Flyway will function as normal. I'll update the tests and remove this warning for the next patch version.



            Running flyway migration on a DB with existing tables
            Asked 2021-Mar-04 at 10:08

            I am running flyway migrations on a postgres DB with existing tables. In doing so flyway threw this error



            Answered 2021-Mar-04 at 10:08

            Yes, you'd set it only once. That approach is really only used where Flyway takes all its parameters from the configuration is just intended for a single use (e.g. just for one specific copy of a database, out of many). Normally, you baseline from an action at the command line like this:



            Merge 2 schemas from Postgres DBs with different flyways
            Asked 2020-Oct-22 at 10:51

            I currently have 2 databases used by 2 services (let's call them database/service A and database/service B), both of them with their own schemas.

            I need to migrate some of the tables from DB A into DB B, once that's all completed re-point service A to service B. I know could easily do the schema migration by using pg_dump utility and that seems to be the "easy" bit.

            The problem I have is that both services use Flyway for database version control, hence when I re-point service A to DB B there's a bunch of migrations that are clashing on the same version number because of checksum mismatch.

            I've seen that there's a "baseline" functionality in Flyway (, but at first look that doesn't seem to be what I need.

            How could I resolve this problem?



            Answered 2020-Oct-21 at 12:20

            On first considering this problem, the immediate answer is that your move from DbB to DbA is done through one migration on top of the existing migrations in DbA. You don't try to modify the database outside of the Flyway process. Instead, you incorporate the Flyway process into your database change. Flyway is very agnostic to the set of changes you introduce. So, you're just adding another change to the existing set. This shouldn't result in a repair or a baseline to get to the required point.

            Let's say the last migration for DbA is V6.3__XXX, we just add V6.4__MigratingDbB to our chain of changes. What's in that script is the necessary set of changes. That should do it.



            Generate sql statements with flyway placeholders
            Asked 2020-Aug-24 at 18:25

            I trying to save some sql insert statements to files to use them for testing. I would like to use flyway placeholders for that but I'm not able to find any.

            Some example in Java:



            Answered 2020-Aug-24 at 18:25

            Flyway's placeholders are no different from any other "vendor specific" SQL syntax, which isn't supported out of the box by jOOQ, so plain SQL templating has the answer.
