DECODE(SUBCOM_TYPE ,'S','SPECIAL COMMISSION','D','DEFAULT COMMISSION') AS SUBCOM_TYPE,
TO_CHAR(FROMDATE,'DD-MON-YYYY') AS FROMDATE, 
TO_CHAR(TODATE,'DD-MON-YYYY') AS TODATE,
TO_CHAR(ADDEDDATE,'DD-MON-YYYY') AS ADDEDDATE,
USER_CODE from COMMISSION 
where INST_ID = 'ABC' AND MASTERCODE='106'

Answer 1

你可以使用CASE函数

Select .....
CASE SUBCOM_TYPE
WHEN 'S' THEN 'SPECIAL COMMISION'
WHEN 'D' THEN 'DEFAULT COMMISION'
END
