Can Flyway Desktop avoid comparing objects inside schemas that I haven't specified?

anthonym

Scenario:

* I'm using Flyway Desktop 7.6.0, in either "Schema model" or "Migrations" mode

* There is one Postgres DB function in our "insights" schema that uses a SQL BODY instead of PL/pgSQL.

* I've specified a bunch of DB schemas for the project, excluding that one schema: "insights"

* The DB comparison step fails with this error: "Error registering comparison sources -- The function my_sql_body_function() was declared using the sql_body form, which is not yet supported."

Question: Is there a way to tell Flyway Desktop to ignore that sql_body function in the "insights" schema, and only compare objects in the schemas that I've specified?

Hi Anthony,

Apologies for the issues you’re experiencing with Flyway Desktop.

Could you please:

1. Share a copy of the Flyway Desktop logs?
2. Let me know if you’re already using a filter file to focus on the schemas relevant to your project?

If you’re not already using a filter, you’ll need to create one to define which objects Flyway should compare. You can create a filter file by following the steps outlined in the documentation for PostgreSQL filtering: PostgreSQL and MySQL Filtering Documentation.

Once you’ve set up the filter:

• Add it to the flyway project directory and rerun. 

If the issue persists after applying the filter, please send over both the Log and TOML file, and we can investigate further.

Best, 

Hassan

Thank you Hassan, I will try creating a filter file.

Follow-up question: What does the "Schemas" list actually do in the "Connect to a target database" dialog? Does it not filter the schemas that are compared by the project?

Follow-up question #2: What is the filter file format to exclude an entire schema of objects? The documentation isn't clear on how to do that.

I would like to exclude our entire "insights" schema, something like this:

{

    "version": "1.1",

    "postFilters":

    [

        {

            "filterTarget": "schema",

            "filterBy": "name",

            "filterValue": "insights",

            "effect": "exclude"

        }

    ]

}
