Need equivalent CE_JOIN statement for SQL Join Statement

Hi All,

I need a CE_JOIN code for the SQL code below;

select a.c1,

          a.c2,

          a.c3

  from table1 as a

inner join table 2 as b

where a.c1 ne b.c1.

usually if the condition is "equals" then the CE_JOIN would be

CE_JOIN(a, b, [c1], [c1,c2,c3])

But i dont know how to write the logic for not equals to .

Can someone please help me on this??

Best regards,
Mahesh
