Syntax Error while Creating Partition with MOD Function

 Hi, 

I am trying to create a MOD Based Partition table, but getting a syntax error. Can someone help me ?

CREATE TABLE PAR_MODU

(

   A1   NUMBER (22) NOT NULL,

   B1   NUMBER (22) NOT NULL

)

PARTITION BY RANGE (MOD(A1,10)

   (PARTITION P1 VALUES LESS THAN 1));
