我正在尝试更新一个具有加密弧几何的表：

update aip_radiofrequencyarea 
set extent_arc = SDO_GEOM.SDO_ARC_DENSIFY(
                   extent,
                   MDSYS.SDO_DIM_ARRAY(
                     MDSYS.SDO_DIM_ELEMENT('X',3460000,3475000,0.005),
                     MDSYS.SDO_DIM_ELEMENT('Y',5500000,5635000,0.005)
                   ),
                   MDSYS.SDO_DIM_ELEMENT('Z',0, 1000, 0.005),
                   'ARC_TOLERANCE=0.005'
                 );

这是我得到的错误消息：

SQL-Fehler: ORA-06553: PLS-306: wrong number of Arguments in 'SDO_ARC_DENSIFY'
06553. 00000 -  "PLS-%s: %s"
*Cause:    SQL compilation failed because of an illegal reference to a
           PL/SQL unit.
*Action:   If the PL/SQL error message does not provide a workaround, then
           try the SQL statement as a top-level call as the appropriate user
           with the appropriate privileges.

有人知道为什么吗？
