Search Queries Count

What is the total number of search queries stored in the system?

  • Aggregation

Challenge brief

Understand the request

Data Engineering is validating the search pipeline and needs the total row count in the search_queries table as a data quality check.

Return total_queries in the declared deterministic order.

Return

  • total_queries

Constraints

  • Return one row with the total stored-query count

Data you will use

Review the relevant tables before deciding how to join, filter, or aggregate them.

search_queries

  • query_idINTEGER
  • user_idINTEGER
  • query_textVARCHAR(200)
  • search_dateDATE

Hints, when you need them

Open one clue at a time so you still do the reasoning.

Hint 1

Use the search-event table at its stored row grain.

Hint 2

A single aggregate can produce the result.

Hint 3

Expose the aggregate with the requested name.

Verified SQL answer

Attempt the problem first, then compare structure and reasoning—not just syntax.

Reveal solution and explanation
SELECT COUNT(*) AS total_queries FROM search_queries

Why this works

There are 42 rows in search_queries — 42 individual search events. User 1 alone accounts for 14 of them (queries 1, 2, 11, 21, 31-40).

Success check

Returns the complete deterministic result for search queries count

Expected result

Use this output to verify values, aliases, ordering, and row count.

total_queries
44
