                                          SdaiInvocationId  *edmiInvocationId);

Returns a numeric attributeID that uniquely identifies an attribute definition instance in the remote EDMdatabase. The attribute is uniquely specified by the names of the Express Schema, the entity and the attribute it self. If the attribute name is not unique within the entity, it must be qualified by the name of the entity from which it is inherited. The returned attributeID will not change throughout the lifetime of its attribute definition instance in the EDMdatabase. It may be used to identify the attribute in subsequent EDMinterface operations.

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiString	schemaName	The name of the Express Schema in the remote EDMdatabase in which the attribute is defined.
SdaiString	entityName	The name of the entity in which the attribute is defined.
SdaiString	attributeName	The name of the attribute for which to retrieve the attributeId.
SdaiAttr	attributeId	Variable that will receive the returned attributeId.
SdaiInvocationId	edmiInvocationId	Currently not used.
