The code below is provided to generate an example dataset for use in the example queries present in this tutorial. Assuming that you have the proper credentials to create a new schema and create a new table, you can run these statements with either a notebook or Databricks SQL. The followin...
When ROWS is specified, the sample_number expression must evaluate to an integer value greater than zero. REPEATABLE Indicates that the selected sample can be returned again. When specified with the same repeat_seed value, SQL Server returns the same subset of rows as long as no changes have ...
TDD is more challenging in database development because you need to provide a consistent test environment to verify code prior to checking in changes. For a database unit test to run successfully it must have the appropriate schema as well as the proper data. This means that in order to run...
When specified with the same repeat_seed value, SQL Server returns the same subset of rows as long as no changes have been made to any rows in the table. When specified with a different repeat_seed value, SQL Server will likely return some different sample of the rows in the table. The...
