13.6 Filtering and Sorting Query Results
When working with SQL, you will often need to choose specific data from a table. This can be done using the SELECT statement, which can then be followed by the WHERE clause to filter the data and the ORDER BY clause to sort it.
The WHERE clause allows you to specify conditions that must be met for a particular row to be included in the results. For example, you can use the WHERE clause to select only the rows where the value in a certain column is greater than a specific number. The ORDER BY clause, on the other hand, allows you to sort the selected data based on a particular column.
