![]() ![]() To install the synth binary refer to the installation page. Synth uses declarative configuration files (just JSON don't worry) to define how data should be generated. It has integration with Postgres, so you won't need to write any SQL. Synth is an open-source project designed to solve the problem of creating realistic testing data. We could define functions ourselves to generate names / phone numbers / emails etc, but why re-invent the wheel? Using a data generator like Synth # text in your phone column actually being a phone number) we need to get more sophisticated. If you care about your data being semantically correct (i.e. First of all, every company has exactly 1 contact, and more importantly the actual data looks completely useless.

(This time I selected the test tables) Conclusion Using the Back button, we can return to a previous screen to fix reported errors and try again. That happened because that table already contained data! We can see here that a UNIQUE constraint failed on the artists.ArtistId field. Navicat provides a complete report of its progress. Once we're satisfied with the data we can generate it by clicking the Start button. This will give us the opportunity to manually change values or Regenerate all data for a table: The next screen will show us a preview of what the generated data will look like for each table that we selected back on the second screen. Navicat will automatically determine which order to follow when generating data, but we can change it on the Table Generation Order dialog: Data Previews (It goes without saying that you'll want to select empty tables that are based on the real tables that you're testing.) By default, Navicat generates 1000 rows of data, but we can change that value via the Number of Rows to Generate text field: The next screen is where we set which tables and fields to generate data for.

The database that we'll be working with is the chinook sample database for SQLite. We'll familiarize ourselves with it by going through the process of creating testing data for multiple related tables in Navicat Premium 16 for Windows. In today's blog, we'll start with the entirely new Data Generation tool. The recent Navicat 16 listed some of its most note-worthy features and improvements, including:Īs promised, we'll be exploring these in much more detail throughout the coming weeks.
