Filter interviews by
GROUP BY in MySQL is used to group rows that have the same values into summary rows.
GROUP BY is used with aggregate functions like COUNT, SUM, AVG, etc.
It is used to summarize data by grouping rows based on one or more columns.
GROUP BY can be used with HAVING clause to filter the grouped results.
Example: SELECT department, COUNT(*) FROM employees GROUP BY department;
Filtering data in MySQL involves using the WHERE clause in SQL queries.
Use the WHERE clause in SELECT statements to filter data based on specified conditions.
You can use comparison operators such as =, <>, >, <, >=, <=, etc. in the WHERE clause.
You can also use logical operators like AND, OR, and NOT to combine multiple conditions.
Example: SELECT * FROM table_name WHERE column_name = 'value';
