xpxGetEntityInSchema

FUNCTION xpxGetEntityInSchema (schemaIdOrQuerySchemaId     : GENERIC;
                               entityNameOrViewEntityName  : STRING;
                               VAR entityIdOrViewEntityId  : GENERIC) 
                               status                      : INTEGER;

The xpxGetEntityInSchema function returns a numeric entityIdOrViewEntityId  that uniquely identifies an entity or view entity definition instance in the EDMdatabase. An entity  or view entity name is unique within one dictionary model (Express schema). Hence the combination of  <schemaId> and <entityName>  or <schemaId> and <ViewentityName>  identifies one particular entity definition in the EDMdatabase. The actual dictionary model must be open before this function can be successfully performed. If the specified <entityName> is the name of a legal complex entity that does not exist as an entity definition instance in the related dictionary model, an entity definition instance of the actual complex entity, will be created in the related dictionary model. The returned entityIdOrViewEntityId  can be used to identify the actual entity in subsequent EDMinterface operations. The returned entityIdOrViewEntityId  will be a constant value throughout the lifetime of the actual entity definition instance in the EDMdatabase.
