How to Use GROUP BY Clause to Concatenate Strings
The GROUP BY clause in SQL allows us to group rows that have something in common, such as similar values in a particular column. Essentially, GROUP BY lets us take messy data and organize it neatly, making it easier to understand and analyze.
We can concatenate data from several rows inside each group into a single string separated by commas. This feature is useful to compile similar data into each group, such as listing every item in a category or compiling all of the answers to a survey question.
To concatenate strings in SQL, we can use the GROUP_CONCAT function with the GROUP BY clause.
