SQL錯誤：ORA-01403：找不到數據

Question

火災時更新查詢

update JISPBILCORBILLINGPRD501.TBLMACCOUNTADDRESS set Address1='NehateSir',stateid='STT0002' where accountid='ACC000000068' 

那個時候出現這種錯誤

Error starting at line 4 in command: 
update JISPBILCORBILLINGPRD501.TBLMACCOUNTADDRESS set Address1='NehateSir',stateid='STT0002' where accountid='ACC000000068' 
Error report: 
SQL Error: ORA-01403: no data found 
ORA-06512: at "WOM.TRGBILLINGADDRESS", line 10 
ORA-04088: error during execution of trigger 'WOM.TRGBILLINGADDRESS'

Answer 1

這個查詢：

SELECT address1, 
    address2, 
    city_id, 
    state_id, 
    pincode 
INTO add1, 
    add2, 
    cityid, 
    stateid, 
    pincd 
FROM wom.tbltaddress ta 
WHERE ta.ID IN 
    (SELECT vbac.billing_address_id 
    FROM wom.vw_billaddresschange vbac, 
    wom.tbltaddress ita 
    WHERE vbac.billing_address_id = ita.ID 
    AND vbac.lcid     = parlcid 
); 

不會返回導致PL/SQL中發生異常的任何內容。如果你正在使用Oracle 9i以上

BEGIN 
     SELECT address1, 
       address2, 
       city_id, 
       state_id, 
       pincode 
     INTO add1, 
       add2, 
       cityid, 
       stateid, 
       pincd 
     FROM wom.tbltaddress ta 
     WHERE ta.ID IN 
       (
       SELECT vbac.billing_address_id 
       FROM wom.vw_billaddresschange vbac, 
         wom.tbltaddress ita 
       WHERE vbac.billing_address_id = ita.ID 
         AND vbac.lcid = parlcid 
       ); 
EXCEPTION 
WHEN no_data_found THEN 
     NULL; -- or do anything useful 
END; 

，而不是使用在觸發器執行UPSERTMERGE聲明：

應該捕獲該異常。

Answer 2

當心例如

BEGIN 
    SELECT nvl(COUNT(1),0),nvl(MIN(COST),0),DOCUMENTPARTID INTO l_itemexistCount,l_contractcost,l_docpartid 
    FROM CONTRACTPRICE WHERE RESELLERID= l_companyid AND CONTRACTID=l_contractid AND 
    MANUFACTURERPART = l_manufacturerpart and status = 0 AND DOCUMENTPARTID=l_docpartid AND ROWNUM <=1 
    GROUP BY DOCUMENTPARTID ORDER BY MIN(COST) DESC; 
    IF nvl(l_itemexistCount,0) > 0 THEN 
     l_staticStr4 := l_staticStr4 || '\n(' || l_count || ') - ' || l_manufacturerpart || ' [$' || l_contractcost||']'; 
     p_paramout:=p_paramout||','||l_docpartid; 
     l_count:= l_count + 1; 
    END IF; 
EXCEPTION 
    WHEN no_data_found THEN 
    NULL; -- or do anything useful 
END;
