This lesson shows you how to use the SELECT statement’s WHERE clause to specify search conditions.
Database tables usually contain large amounts of data, and you seldom need to retrieve all the rows in a table. More often than not, you’ll want to extract a subset of the table’s data as needed for specific operations or reports. Retrieving just the data you want involves specifying search criteria, also known as a filter condition.
SELECT statement, you filter data by specifying search criteria in the
WHERE clause. You specify the
WHERE clause right after the table name (the
FROM clause), as follows:
SELECT prod_name, prod_priceFROM productsWHERE prod_price = 2.50;
