Count the number of employees in each department sql query

To count the number of employees in each department using an SQL query, you'd use the "GROUP BY" clause to group the data by department and the "COUNT" function to tally the number of employees within each group. This query provides a summary of how many employees are in each department, allowing for easy analysis and reporting. It's a fundamental operation in database management to understand the distribution of employees across different departments within an organization, aiding in decision-making and resource allocation.
The "GROUP BY" clause in SQL Server is used to group rows based on a common column's values. It's typically used with aggregate functions like SUM, COUNT, or AVG to summarize data.
