dataClass.getDataStore( )
dataClass.getDataStore( )
The dataClass.getDataStore( ) method returns the datastore for the specified dataclass.
The datastore can be:
- the main datastore, as returned by the ds command.
- a remote datastore, opened using the Open datastore command.
The SearchDuplicate project method searches for duplicated values in any dataclass.
C_OBJECT($pet)
$pet:=ds.Cats.all().first() //get an entity
SearchDuplicate($pet;"Dogs") // SearchDuplicate method
// SearchDuplicate($1;$2)
// SearchDuplicate(entity_to_search;dataclass_name)
C_OBJECT($1;$pet;$dataStore;$duplicates)
C_TEXT($2;$dataClassName)
$pet:=$1
$dataClassName:=$2
$dataStore:=$pet.getDataClass().getDataStore()
$duplicates:=$dataStore[$dataClassName].query("name=:1";$pet.name)
