There is a command group 'az_datamigration_sql db'. This group of commands could 'manage database migrations to sql db'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_datamigration_sql db_create'.The syntax is: az datamigration sql-db create --resource-group
                               --sqldb-instance-name
                               --target-db-name
                               [--migration-service]
                               [--no-wait]
                               [--scope]
                               [--source-database-name]
                               [--source-sql-connection]
                               [--table-list]
                               [--target-db-collation]
                               [--target-sql-connection]. The 1th example of the child command would be to use it to 'create or update database migration resource with maximum parameters', the syntax is: az datamigration sql-db create --migration-service "/subscriptions/00000000-1111-2222-3333-444444444444/resourceGroups/testrg/providers/Microsoft.DataMigration/sqlMigrationServices/testagent" --scope "/subscriptions/00000000-1111-2222-3333-444444444444/resourceGroups/testrg/providers/Microsoft.Sql/servers/sqldbinstance" --source-database-name "aaa" --source-sql-connection authentication="WindowsAuthentication" data-source="aaa" encrypt-connection=true password="placeholder" trust-server-certificate=true user-name="bbb" --table-list "[Schema1].[TableName1]" "[Schema2].[TableName2]" --target-sql-connection authentication="SqlAuthentication" data-source="sqldbinstance" encrypt-connection=true password="placeholder" trust-server-certificate=true user-name="bbb" --resource-group "testrg" --sqldb-instance-name "sqldbinstance" --target-db-name "db1". The 2th example of the child command would be to use it to 'create or update database migration resource with minimum parameters', the syntax is: az datamigration sql-db create --migration-service "/subscriptions/00000000-1111-2222-3333-444444444444/resourceGroups/testrg/providers/Microsoft.DataMigration/sqlMigrationServices/testagent" --scope "/subscriptions/00000000-1111-2222-3333-444444444444/resourceGroups/testrg/providers/Microsoft.Sql/servers/sqldbinstance" --source-database-name "aaa" --source-sql-connection authentication="WindowsAuthentication" data-source="aaa" encrypt-connection=true password="placeholder" trust-server-certificate=true user-name="bbb" --target-sql-connection authentication="SqlAuthentication" data-source="sqldbinstance" encrypt-connection=true password="placeholder" trust-server-certificate=true user-name="bbb" --resource-group "testrg" --sqldb-instance-name "sqldbinstance" --target-db-name "db1".
