Solution
To count the number of cities in the CITY table that have a population larger than a specified value, you would typically use SQL. Here’s how to frame the solution:
1. Break Down the Problem
- Identify the structure of the CITY table.
- Determine the relevant field for population count.
- Define what "larger than" means in terms of the input value.
2. Relevant Concepts
- SQL COUNT() function to count the number of records.
- SQL WHERE clause to filter the cities based on the population condition.
3. Analysis and Detail
- Assuming the CITY table has at least two columns,
CityName
andPopulation
. - The SQL query would need to filter cities with a population greater than a provided threshold.
4. Verify and Summarize
- The SQL command will execute and return the count of the records that meet the criteria.
SQL Query
Here’s a sample SQL query that achieves the desired outcome:
SELECT COUNT(*) AS NumberOfCities
FROM CITY
WHERE Population > [InputValue];
Final Answer:
Replace [InputValue]
with the specific population threshold to get the count of cities exceeding that population.
