The Query By Example feature provides a simple interface for a user to enter queries. Instead of writing an entire SQL command, the user can just fill in blanks or select items to define the query she wants to perform. For example, a user may want to select an entry from a table called "Table1" with an ID of 123. Using SQL, the user would need to input the command, "SELECT * FROM Table1 WHERE ID = 123". The QBE interface may allow the user to just click on Table1, type in "123" in the ID field and click "Search."
