Use random.choice(someList) and random.shuffle(someList) to assure referential integrity. So you might have ChildEntity picking a random element from ParentEntity to assure that the FK-PK relationship was correct. Instead of generating random keys, you want to make a random selection from the other entities. MyData = įor multiple entities, you have to work out the cardinality. DDL statement for many objects or the whole schema The same works for many objects and even for the whole schema. To do this, press Ctrl+Alt+G or choose Context menu SQL Scripts SQL Generator and get the generated DDL of any kind of object (table, schema, procedure, whatever). Self.append( random.randrange( 100, 1000 ) ) SQL generator helps you to get DDL scripts with options. sql database data-visualization database-gui kpis dummy-data-generator. Here's a stripped-down one-table-only version of a data generator that writes a CSV file. SQURL is a cross-platform desktop application designed for developers who are looking to generate meaningful test data and monitor database KPIs. I actually don't like this as much, but you might. Data Generator includes 200+ meaningful SQL data generators with sensible configuration options. Use an ODBC connection to generate data directly into the database. Overview Features Resources Support Generate Realistic Random Data for SQL Databases in a Wink Implement new standards for the population of SQL tables with random data with our visual data generation tool. Generate CSV files of data which you can load manually. Generally, you want to build an entity model of your own so that you can be sure you have ranges and key relationships correct. Looking at 3 and 4 together, you don't want simple reverse engineering - you want something you can control to produce realistic values. There are ways to discover the database metadata and constraints. The first two indicate that you want to produce script files that will load your data. For generating sample data, I use simple Python applications.Ī repeatable set of data that you can for performance testing and get consistent results.įollow all of the DB referential integrity rules and constraints.
