To extract data from a table by filtering for certain conditions before cleansing, which SQL statement performs this function?

Filtering data retrieved from a table is done with a WHERE clause inside a SELECT query. The WHERE clause specifies conditions (like age > 18, status = 'active', or country IN ('US','CA')) that determine which rows are returned. This lets you extract only the rows that meet your criteria before you perform cleansing or other processing. A SELECT statement fetches data, but it returns all rows unless a WHERE clause restricts them. INSERT adds new rows, and UPDATE changes existing ones. The WHERE clause isn’t a standalone statement—it’s the conditional part of a query that applies to a SELECT (and can also be used with UPDATE or DELETE).
