In
database management systems,
query by example (QBE) refers to a method of forming
queries in which the
database program displays a blank
record with a space for each
field. You can then enter conditions for each field that you want to be included in the query. For example, if you wanted to find all records where the AGE field is greater than 65, you would enter
>65 in the AGE field blank.
QBE systems are considered easier to learn than formal query languages.
