QueryCriteria

The selection criteria for the query. Each QueryCriteria object is made up of the following:

Field or Control	Description
Logical	Any criteria objects after the first must include have a Logical value, either AND or OR.
Expression 1	A field or value that you want to base the selection criterion on, that is, Expression1 is the left-hand side of the criterion's comparison.
Operator	A mathematical or other operator used to specify the relationship between Expression 1 and Expression 2.
Expression 2	A field or other value, also called a comparison value, used with Expression 1, that is, Expression2 is the right-hand side of the criterion's comparison.

In PeopleSoft Query, a QueryCriteria is under the Criteria tab.

Expression can be made up of constant values, fields, subqueries, and so on.
