Has / HasNot
The "has" relation type simply returns the value of another field converted to a boolean value.Attributes/Keys:
- type (required): "has".
- field (required): Name of the field holding the value to convert to boolean.
Field type conversions:
- string: True if the field has length. False for NULL or empty string.
- date: True for any non-NULL value.
- boolean: True for true. False for false and NULL.
- numeric: True for any number over zero.
Example (XML):
<field ColumnName="MyField">
<relation type="has" field="Email" />
</field>Example (setColumn):
<cfset sRelation = StructNew()>
<cfset sRelation.type = "has">
<cfset sRelation.field= "Email">
<cfset Application.DataMgr.setColumn(tablename="MyTable",ColumnName="MyField",Relation=sRelation)>HasNot
The "hasnot" relation type is just like the "has" relation type except that it returns the opposite boolean value.
