Which SQL command is used to make a search more specific?

The SQL command that is used to make a search more specific is the WHERE clause, particularly when combined with the logical operators AND and OR. The WHERE clause allows you to filter records based on certain criteria, ensuring that only those records that meet specific conditions are included in the result set.

By using AND, you can specify that multiple conditions must be true for a record to be selected. For example, if you want to retrieve records of students who are both in a specific grade and have a certain GPA, you can combine these conditions using AND. On the other hand, OR allows you to specify that at least one of multiple conditions must be true, broadening your search criteria. For instance, you can search for students who either belong to a specific class or have a certain major.

This level of detail in data retrieval is essential for obtaining meaningful results from a database, which is why the combination of WHERE with AND and OR is critical for refining searches effectively. Other options, such as SELECT, FROM, and ORDER BY, serve different functions within an SQL statement but do not specifically enhance the specificity of the search conditions in the same way that the WHERE clause does.
