Hi Summit/Bart, The sys_keys table can then be queried to verify if the index type of the table is column, row (index, or bitmap) wise:
SQL> SELECT TOP 10 KEY_TABLE, sys_sql_val_print (KEY_OPTIONS) FROM sys_keys WHERE KEY_TABLE = 'DB.DBA.RDF_QUAD' ; KEY_TABLE sys_sql_val_print VARCHAR NOT NULL VARCHAR _______________________________________________________________________________ DB.DBA.RDF_QUAD vector ('column') DB.DBA.RDF_QUAD vector ('distinct', 'no_pk', 'column', vector (525, 0, 0, '__ALL', vector (vector (0, 'S', 1, 16776960, 0)))) DB.DBA.RDF_QUAD vector ('distinct', 'no_pk', 'column', vector (525, 0, 0, '__ALL', vector (vector (0, 'O', 3, -1, 65535)))) DB.DBA.RDF_QUAD vector ('column', vector (525, 0, 0, '__ALL', vector (vector (0, 'O', 3, -1, 65535)))) DB.DBA.RDF_QUAD vector ('distinct', 'no_pk', 'column', vector (525, 0, 0, '__ALL', vector (vector (0, 'S', 1, 16776960, 0)))) 5 Rows. -- 1 msec.
