--------------------------ORACLE数据库分页SQL举例------------------------------------------------
SELECT * 
FROM ( 
        SELECT TEMP.*, ROWNUM AS NUM
        FROM (
                SELECT EB.EHR_ID,EB.PERSON_NAME,CL.SVC_ID a,BILL.SVC_ID b,BILL.ITEM_NAME
                FROM PHIS.EHR_BASE EB, PHIS.SVC_CLINIC CL,PHIS.SVC_CLINIC_BILL BILL
                WHERE EB.EHR_ID = CL.EHR_ID
                AND CL.SVC_ID = BILL.SVC_ID
        ) TEMP
) 
WHERE NUM <= 5
AND NUM > 0
