            Maven flyway Found non-empty schema(s) "PUBLIC" but no schema history table
            Asked 2022-Apr-04 at 16:59

            I am just learning Spring Boot with Maven and I have encountered an error that I cannot resolve. I have attached a dependency from Flyway and when I want to install it (I'm clicking install on Lifecycle), I get this error:

            Found non-empty schema(s) "PUBLIC" but no schema history table. Use baseline() or set baselineOnMigrate to true to initialize the schema history table.

            What could be causing this and how to fix it?

            I'm using Java 8 and my dependency with Flyway looks like this:

            Spring Boot is trying to run Flyway migrate as part of a maven goal it has configured.

            Found non-empty schema(s) "PUBLIC" but no schema history table.

            The error message is stating that the default schema which Flyway is trying to run against, which is PUBLIC, is not empty. As a result, Flyway know needs to know what the state the database before it is able to create a schema history table and migrate.

            Use baseline() or set baselineOnMigrate to true to initialize the schema history table.

            These are the two ways you can correct this by creating a baseline to build your migrations upon.

            In spring boot, baseline on migrate can be configured with spring.flyway.baselineOnMigrate=true.

            Additionally, install in Maven does not mean install the dependencies but builds and puts the build artifacts of your product in your .m2 maven repository.



            Milo OPC-UA Client NoSuchMethod error with io.netty.buffer.ByteBuf.writeMediumLE(int)
            Asked 2022-Mar-21 at 22:29

            I downloaded the sample code from GitHub and modified the just to make sure that I can connect to an OPC Server (not Milo, it's a C#-based OPC Server). I was able to verify that the sample code is able to read/write/call nodes from my server with the modifications.

            I then reimplemented what I thought I needed into my actual project, but I might be missing something since I cannot connect under this project and receive the following error:

            java.lang.NoSuchMethodError: 'io.netty.buffer.ByteBuf io.netty.buffer.ByteBuf.writeMediumLE(int)'

            This error happens in the while running createClient() I can still run the sample project and still connects.

            Here's my pom.xml: The org.milo is added near the end and I added what I saw was added from the sample (included ch.qos.logback and jetbrains). Then added the io.netty thinking it would help, but still have the same error.



            Answered 2022-Mar-21 at 22:29

            It seems that your actual project has an old version of Netty somewhere on its classpath.

            ByteBuf::writeMediumLE (and all the other LE-suffixed ByteBuf methods) were introduced in Netty 4.1.



            How to populate seed data using flyway
            Asked 2022-Mar-17 at 19:56

            We have a countries table, which contains the country names which will never change.

            How to populate country specific seed data using flyway on application start preferably with the same primary keys, so that it doesn't change across environments (say dev, qa, prod)



            Answered 2022-Feb-15 at 14:17

            It somewhat depends on your database structure but you can have the insert statements for your country names as a migration script with set primary keys.

            If you have Flyway as part of your Java application, you would have Flyway Migrate run on application start up. This would allow the application to deploy the country names to a new environment when run and since its a migration script it would not run again if the environment has already had it run prior as it would be in the schema history table. You could also add to the table if more names are required and alter names as well via subsequent migration scripts.

            The only issue with this would be making sure nothing else adds to this table outside of the migration scripts you have created as primary key clashes would cause the migration to fail.

            Correct configuration for Stryker on Angular v11 Library project?
            Asked 2022-Feb-18 at 18:19

            The instructions for setting up an Angular application project are straightforward. I have had no issue with setting up and running Stryker on an application project using default settings for Karma. I am having trouble getting it to work correctly when it is a Library project instead, however.

            I have looked through the configuration documentation for Stryker and I have tried adjusting the paths to the relevant files (for mutation and the karma.config)




            Answered 2022-Feb-18 at 18:19

            With help from nicojs, I was able to get basic Stryker functionality working on my library project.

            As it turns out I was missing some critical configuration.

            I was able to set the testRunner as karma. I added karma.ngConfig.testArguments.project and disableTypeChecks values in stryker.conf.json



            Snowflake SQL Statement to retrieve the current organizational account
            Asked 2022-Feb-15 at 21:18

            In snowflake I have 3 accounts setup. What I'm looking for is a way to write a query to determine which account the query is running against. I cannot find any way to determine which account the current connection is using.

            Additional background What I really have is DDL creation scripts checked into source control and I'm using Flyway to turn these scripts over into the different accounts, which is working well with one exception. Some of the artifacts that are being created are Snow Pipes, which have paths to storage accounts in them.

            What I'm trying to do is modify the SQL scripts, so that they will generate the paths to the correct storage accounts depending on the organizational account that the query is running in.

            Adding users via flyway DB migration
            Asked 2022-Feb-07 at 16:03

            I've read in some articles that it's best practice NOT to add DB users via flyway db migration. It's not very clear to me as to why it's not a good practice. One thing we thought about is that it might be good to have the user configuration automatically documented in the code.

            One article mentioned that you might want different user configuration for different environments. But you could also control that in flyway.

            When/why would you not want to add DB users using flyway DB migration?



            Answered 2022-Feb-07 at 16:03

            If I'm deploying a new user for the database that will be common across all environments, I would absolutely make the creation of that user a part of the Flyway deployment scripts. It fundamentally makes sense. "Version 43.43 is where we added the login snarglegrass to the app."

            On the other hand, if you are working on setting up different environments with varying permissions, I probably will make that part of the flow control commands in pre/post deployment scripts instead of using Flyway. The reason for this is because it can be challenging to write the scripts in such a way as they're repeatable and safe. You could still do it that way though.



            what is diffrent between windows and linux version?
            Asked 2022-Jan-26 at 16:08

            We want to put the flyway folder on my application directory and release it, and our clients use both of the linux and windows server. We used sql-base migrations and Flyway command-line tool. what is diffrent between windows and linux platform tools? Can we use a linux platform tools for both? if no, what are same file or directory?



            Answered 2022-Jan-26 at 16:08

            The difference between the Linux and Windows versions of Flyway is the type of Java Runtime Environment they include (e.g. java or java.exe), so you should make sure the contents of flyway-/jre match the client's platform. Everything else should be the same.

            Are you using Spring WebClient to do REST backend calls? If that's the case, then something is wrong with your WebClient bean configuration for the analyticsService for the test profile.

            If your're not using Spring Webflux, just remove it from the dependencies.
