You can add the Liquibase Pro license inside the DBeaver user interface.Īlternatively, you can add the following line to your db.ini file. You’ll get a license key that you’ll use in the next step. If you’re not already using Liquibase Pro, get your free 30-day trial. Once downloaded, install the selected software. Install and Configure DBeaver Enterprise Editionĭownload DBeaver and select DBeaver Enterprise, DBeaver Ultimate, or Team Edition. Here are the steps to install it and take it for a ride. Want to try it out? Let me show you how you can do it for free! This integration simplifies the task and brings you closer to the CI/CD party. In this edition, you can use DBeaver to compare databases and automate it in your CI/CD flow. If you want to make those databases identical in automation, you will want to look at DBeaver Enterprise Edition. Recently, our friends at DBeaver updated their DBeaver Enterprise, DBeaver Ultimate, and Team Edition versions to take advantage of Liquibase Pro and support database schema comparisons so you can quickly see any difference between databases. So remember – table creation can do more than just create a table in a database.Liquibase and DBeaver have teamed up to give you the most advanced database comparison functions to get ahead in the automation game making your life easier. These types of tasks help prevent errors in the data and are likely to prevent future headaches. We can replace some downstream tasks such as default values and provide uniqueness. It’s important to recognize the capabilities of table creation and it’s possibilities. We can also include foreign keys in our tables if needed or even create tables from a select statement. These are just some of the create table examples possible. SQLite Unique Constraint Failure Final Thoughts With the constraint applied, had we tried to insert the same value twice into CompanyNumber the database would return an error. As an example, we may want our CompanyNumber field to be unique on our Company table. This is so that we ensure no duplicate values occur on a specified field. Sometimes unique constraints are necessary to apply to a table. Normally, we would expect the Country and IsFortune500 fields to return NULL, but since we default the values they return our specified defaults. INSERT INTO Company (CompanyName, CompanyNumber, AddressLine1, AddressLine2, City, State, PostalCode) We can drop and recreate our company table with the above DDL to then provide an insert statement that DOES NOT include the country and fortune 500 flag. As an example, if no country or fortune 500 flag is provided, we can include a default value. This is helpful if we want to avoid adding logic to an ETL process or script since the table can auto-populate the default instead. Tables can be created with default values. VALUES (‘AllThingsSQL’,’1234′,’543 John Doe Way’,’Apt 7′,’Fantasy Land’,’IL’,’60430′,’United States’,’0′) Īs we can see, the resulting output would start at an initial value of 1. INSERT INTO Company (CompanyName, CompanyNumber, AddressLine1, AddressLine2, City, State, PostalCode, Country, IsFortune500) We can then include an insert statement to see what the output would be. In the case of SQL Server we apply an initial value as well as the incremental increase for each value. For example, in SQL Server we would replace the first column with “CompanyId INT IDENTITY(1,1) PRIMARY KEY“. This will allow the table to auto-populate an id with an increment of 1 starting from an initial value of 1. If we wanted to ensure that our table automatically applied an ID value to the CompanyId field, we could add the AUTOINCREMENT keyword. The database automatically applies a name to the primary key. Create Company Table w/ Primary KeyĪs we can see, all we need to include is the primary key keyword (in SQLite db) to apply the primary key value to the table. In the example of the Company table, we would want to make the CompanyId field our primary key. A primary key is normally used on a table as a unique identifier. We can easily include primary keys into a table. Let’s look at a few other create table examples. This is something to be aware of although theses limits are normally very high and never reached. We can then continue to include as many columns needed with as many datatypes as needed. Create Company TableĪt its core, a table can be created at a bare minimum with one column. This is a simple example if we were looking to create a basic Company table. There are also important components that can be added to a table during its creation such as a primary key, identity columns, indexes and more. Creating a standard table is fairly straight-forward. Specifically for tables, we use the CREATE TABLE command. When creating any objects we use the CREATE keyword.
