Class ERXModuloQualifier

java.lang.Object
  com.webobjects.eocontrol.EOQualifier
      com.webobjects.eocontrol.EOKeyValueQualifier
          er.extensions.eof.ERXModuloQualifier

All Implemented Interfaces:

com.webobjects.eocontrol.EOKeyValueArchiving, com.webobjects.eocontrol.EOQualifierEvaluation, com.webobjects.foundation.NSCoding, java.io.Serializable, java.lang.Cloneable

public class ERXModuloQualifier
extends com.webobjects.eocontrol.EOKeyValueQualifier
implements java.lang.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
