Class ERXModuloQualifier

java.lang.Object

com.webobjects.eocontrol.EOQualifier

com.webobjects.eocontrol.EOKeyValueQualifier

er.extensions.eof.ERXModuloQualifier

All Implemented Interfaces:

EOKeyValueArchiving, EOQualifierEvaluation, NSCoding, Serializable, Cloneable

public class ERXModuloQualifier
extends EOKeyValueQualifier
implements Cloneable

The ERXModuloQualifier is useful for creating qualifiers that will generate SQL using the 'mod' key word.

For example constructing this qualifer:
ERXModuloQualifier q = new ERXModuloQualifier("userId", 3, 5); Then this qualifier would generate SQL of the form: ... where mod(userId,5)=3; Note that this syntax is Oracle specific
