Using GROUP_CONCAT() with GROUP BY in MySQL
In MySQL, the GROUP_CONCAT() function concatenates values from multiple rows into a single string. It is often used with GROUP BY to combine values from each group into one aggregated result.
Aggregates values from a column within each group defined by GROUP BY.
Can specify a separator other than the default comma using
SEPARATOR, e.g.,GROUP_CONCAT(name SEPARATOR '; ').Useful for creating lists, summaries, or reports where multiple entries per group need to be represented in one row.
Works with other aggregate functions for complex summaries.
Using GROUP_CONCAT() with GROUP BY allows you to transform multiple row data into a single, readable string per group, which is especially helpful for reporting and exporting summarized data.
