The SET_TRANSFORM
procedure adds a single transformation record to a transformation list.
DBMS_DATA_MINING_TRANSFORM.SET_TRANSFORM ( xform_list IN OUT NOCOPY TRANSFORM_LIST, attribute_name VARCHAR2, attribute_subname VARCHAR2, expression VARCHAR2, reverse_expression VARCHAR2, attribute_spec VARCHAR2 DEFAULT NULL);
SQL expressions that you specify with SET_TRANSFORM
must fit within a VARCHAR2
. To specify a longer expression, you can use the SET_EXPRESSION
procedure, which builds an expression by appending rows to a VARCHAR2
array.
