Hi Lyall,
Recent versions of Oracle will support this syntax:
SELECT
SUM(CASE TO_CHAR(inv_td,'YYYY') WHEN TO_CHAR(SYSDATE,'YYYY') THEN ord_tot
ELSE NULL END) "TY Tot",
SUM(CASE TO_CHAR(inv_td,'YYYY') WHEN
TO_CHAR(TO_NUMBER(TO_CHAR(SYSDATE,'YYYY'))-1) THEN ord_tot ELSE NULL END)
"LY Tot"
FROM ar_inv_hdr;
There might be a better way for last year -- this is off the top of my head.
HTH! GL!
