SQL & PL/SQL

FUNCTION addNewRow(aTable IN VARCHAR2,
aCols IN VARCHAR2,
aValues IN VARCHAR2)
RETURN tc_ResultSet IS

v_sql VARCHAR2(2000);
vc_ResultSet tc_ResultSet;
v_rowID UROWID;

BEGIN

v_sql := 'INSERT INTO ' || aTable ||' (:a) VALUES (:b) RETURNING rowid INTO :c';
EXECUTE IMMEDIATE v_sql USING aCols, aValues RETURNING INTO v_rowID; <<<<<----- ERROR ORA-00928 missing SELECT keyword

v_sql := 'SELECT * FROM ' || aTable || ' WHERE ROWID = :d';
OPEN vc_ResultSet FOR v_sql USING v_rowID;

RETURN(vc_ResultSet);

END addNewRow;
