The flyway-dev command line is installed as part of Flyway Desktop.  For the latest information, run:

flyway-dev --help

As of October 2022:

Run help on each command above for more details about it's usage.

flyway-dev [command] --help

Examples:

Example One: Creating a new project and saving database changes to the schema model on disk

1. Create a new project giving it a name and path:

   flyway-dev init --name=TestFdCmdLine --path=C:\Users\redgate\Documents\TestFdCmdLine --database-type=SqlServer --i-agree-to-the-eula

   If the folder doesn't exist, it will be created.   
   
    
   
   

2. Update the development database in the user (-u=true) or project settings (-u=false; this is the default)
   

3. See the differences between your Development Database and your Schema Model on disk and save this into an artifact (in temp folder) for later use:
   

   flyway-dev diff -p=C:\Users\redgate\Documents\TestFdCmdLine --from=Dev --to=SchemaModel -a=C:\Users\redgate\Documents\TestFdCmdLine\Temp\artifact1 --i-agree-to-the-eula

   In this example, there's only one table in the database.  Since this is a new project, this appears as the only difference:
   
   
   The schema-model folder is still empty:
   
    
   
   

4. You can see the differences in the artifact using the show command:
   

   flyway-dev show -p=C:\Users\redgate\Documents\TestFdCmdLine -a=C:\Users\redgate\Documents\TestFdCmdLine\Temp\artifact1 --i-agree-to-the-eula

5. Apply the differences to the schema-model folder using the artifact in the previous step:
   

   flyway-dev apply -p=C:\Users\redgate\Documents\TestFdCmdLine -a=C:\Users\redgate\Documents\TestFdCmdLine\Temp\artifact1 -c=VGFibGU6W2Rib10uW1Rlc3RUYWJsZV0 --i-agree-to-the-eula

   

   
   The schema model on disk is now updated:

   

Next steps:

Continue to use flyway-dev [command] --help to continue working with the command line.

1. Use project-update to setup your shadow database.
2. Use diff with --from=SchemaModel --to=Migrations to see the database changes on disk that have not been included in a migration script yet.
3. Use generate to take the differences in the artifact created in the previous step and generate the next versioned migration script.
4. Use promote to save the migrations to the project.

Example Two: Get the version information for the next migration script

1. If a project has been created, use next-migration-name with the path to the project and a description to get the next filename you should use for your migration scripts.
   

Example Three: Initialize a new project and generate a baseline script

# Create a project (Oracle)
flyway-dev init -n ProjectName -p C:\WorkingFolders\FWD\ProjectFolder --database-type Oracle --i-agree-to-the-eula

# Get the differences from Production like DB
$diffs = echo '{ "url": "jdbc:oracle:thin:@//localhost:1521/Production", "user": "OracleUser", "password": "OraclePassword", "token": null, "schemas": ["SchemaName"], "resolverProperties": [] }' | flyway-dev diff -p 'C:\WorkingFolders\FWD\ProjectFolder' -a 'C:\WorkingFolders\FWD\ProjectFolder\artifact.zip' --from Target --to Empty --output json --i-agree-to-the-eula | ConvertFrom-Json

# Generate the baseline from all differences
echo $diffs.differences.id | flyway-dev generate -p 'C:\WorkingFolders\FWD\ProjectFolder' -a 'C:\WorkingFolders\FWD\ProjectFolder\artifact.zip' -o 'C:\WorkingFolders\FWD\ProjectFolder\migrations' --name 'B1__BaselineScript.sql' --versioned-only --i-agree-to-the-eula
