You are counting the rows that match the conditions.

The following creates the result set you want, though different commands:

  selected ID, decode (ASSIGNED_GRP, zero, decoded (ASSIGNED_ID, zero, '*', '-1', '*', ASSIGNED_ID), ASSIGNED_GRP), count (*) t where assign_grp is not empty In or (assigned_id is not empty and Assigned_id & Lt; & Gt; -1) ID, Decoded (ASSIGNED_GRP, Zero, Decode (ASSIGNED_ID, Zero, '*', '-1', '*', ASSIGNED_ID), ASSIGNED_GRP) Group by order 1, 2;
