We will also create one RESTful endpoint that will be used to retrieve all the persisted customers.Īfter creating this first version of our application, we then will refactor it to extract contact details to an entity of its own, Contact. We will use Flyway to create the database schema (a single table) with some data. We will start with an empty Spring Boot application where we will first add a Customer entity with contact details (contact name, email address and phone) directly on it.

To better understand how Flyway, and other solutions that handle version control of databases, can help us, let's do a practical exercise. In the next section, we will see Flyway in action with Spring Boot. These plugins make smooth the usage of Flyway with some popular frameworks like Spring Boot, Grails and Play. But, even if we don't use one of-or don't want to integrate with-these build tools, we can still use Flyway through a CLI tool, or directly through its API.īesides these options, a few plugins were crafted by the developers community. Out of the box, Boxfuse made available plugins to Maven, Gradle, Ant and SBT. How Can We Integrate Flywayįlyway easily integrates with most of the build tools available on the Java environment.

Take a look at Flyway's documentation for more. If needed, developers can change the name of the table that Flyway uses, whether migrations can be run out of order or not, where these scripts are, and etc.

Most of the default properties used by Flyway to control the version of the database can be changed. sql, Flyway is able to query the schema_version table to see on what version the database is and can figure it out what scripts it needs to run. Then when a developer adds a second script, naming it as something like V2_another_script. When Flyway syncs up the database with this script, it adds to the schema_version table a record like this: installed_rank | version | description | type | script | checksum | installed_by | installed_on For example, let's say that our script is called V1_users. Then Flyway adds to it a record identifying that the first migration occurred. in the first migration), it creates a table called schema_version, with the following definition: # column name | column typeĭescription | varchar ( 200 ) type | varchar ( 20 ) Internally, Flyway controls the version of a database through records on a specific table in the database itself.

description: a text with words separated by underscores or spacesįor example, the following are all valid Flyway scripts:.separator: which defaults to _ (two underscores) and separates the version from the description.a version: dots or underscores separated in as many parts as one likes.Usually this directory is classpath :db /migration, but one can change the default value if needed. Whenever a developer needs to change the schema of a database, or to issue some changes to the data residing on it they need to create a SQL script, following a name convention in the directory read by Flyway. How Does Flyway Worksįlyway works by checking the current version of the database and by applying new migrations automatically before the rest of the application starts.
SALESFORCE DBSCHEMA MANUAL
With it, we can tightly integrate plain SQL scripts in the lifecycle of an application, guaranteeing that its database will always be compatible without manual intervention. What is Flywayįlyway is a tool, developed by Boxfuse, that enables developers to apply version control practices to the database that supports a Java application. But, what about our data and the schema that represents it? How do they keep in sync with the application that manipulates it? In this article, we are going to learn about Flyway, a solution that helps developers to handle version control of database schemas and data on Java applications.
SALESFORCE DBSCHEMA CODE
Source code versioning is a subject that has been widely discussed and which has many solutions created to address it, like Git, Subversion and Mercurial.
