  6. Paste the following in the query editor:

     CREATE TABLE default.people10m OPTIONS (PATH 'dbfs:/databricks-datasets/learning-spark-v2/people/people-10m.delta')

Step 2: Query the table

  1. Paste in a SELECT statement that queries the number of women named Mary:

     SELECT year(birthDate) as birthYear, count(*) AS total
     FROM default.people10m
     WHERE firstName = 'Mary' AND gender = 'F'
     GROUP BY birthYear
     ORDER BY birthYear
  2. Press Ctrl/Cmd + Enter or click the Execute button.

    Execute query

    The Limit 1000 checkbox is selected by default to ensure that the query returns at most 1000 rows. If you want more rows, you can unselect the checkbox and specify a LIMIT clause in your query. The query result displays in the Table tab.
