Question

[运行DB2 UDB版本9]为什么这个SQL语句有效

SELECT 
       CASE
       WHEN A.DAILYDOWNLOADSIZE is null THEN 0
    else bigint(A.DAILYDOWNLOADSIZE)
       END "DAILYDOWNLOADSIZE",
       CASE
       WHEN A.DAILYDOWNLOADTIME is null THEN 0
    else bigint(A.DAILYDOWNLOADTIME)
       END "DAILYDOWNLOADTIME"
FROM 
EDMPROD.MQT_STB_FACTS A

......当这个没有

时

SELECT DISTINCT 
bigint(A.CAMID) AS "CAMID",
bigint(A.RID) AS "RID",
A.SOFTWAREVERSION,
A.MODELNUMBER,
A.MANUFACTURERID,
A.MODDATE,
A.POSTTIME,
A.DELIVERYMETHOD,
bigint(A.UPTIME )  AS "UPTIME",
bigint(A.NUMBEROFRESETSSINCELASTSWDL )  AS "NUMBEROFRESETSSINCELASTSWDL",
bigint(A.NUMBEROFSEARCHSIGNALOSDTUNER1 ) AS "NUMBEROFSEARCHSIGNALOSDTUNER1",
bigint(A.NUMBEROFSEARCHSIGNALOSDTUNER2 ) AS "NUMBEROFSEARCHSIGNALOSDTUNER2",
bigint(A.NUMBEROFUSERDISKREFORMATS ) AS "NUMBEROFUSERDISKREFORMATS",
bigint(A.NUMBEROFSYSTEMDISKREFORMATS ) AS "NUMBEROFSYSTEMDISKREFORMATS",
bigint(A.NUMBEROFRECOVEREDDISKERRORS ) AS "NUMBEROFRECOVEREDDISKERRORS",
IPINFO,
       CASE
       WHEN A.DAILYDOWNLOADSIZE is null THEN 0
    else bigint(A.DAILYDOWNLOADSIZE)
       END "DAILYDOWNLOADSIZE",
       CASE
       WHEN A.DAILYDOWNLOADTIME is null THEN 0
    else bigint(A.DAILYDOWNLOADTIME)
       END "DAILYDOWNLOADTIME",
bigint(A.TOTALNUMBEROFDOWNLOADSSTARTED ) AS "TOTALNUMBEROFDOWNLOADSSTARTED",
bigint(A.TOTALNUMOFCOMPLETEDDLS ) AS "TOTALNUMOFCOMPLETEDDLS",
CURRENT_DATE AS "LOAD_DATE"
FROM 
EDMPROD.MQT_STB_FACTS A

我收到错误 SQL0420N在字符串参数中找到无效字符功能“BIGINT”。 SQLSTATE = 22018 即可。

通过对查询进行疑难解答，我确认罪犯是两列DAILYDOWNLOADSIZE和DAILYDOWNLOADTIME。两者都必须从字符（15）转换为bigint。

第二个SQL语句不起作用???

Answer 1

我对此失去了理智，所以我在我的临时表（EDMPROD.MQT_STB_FACTS）中做了一个简单的更改。

我没有将列作为字符键入然后将它们作为bigint转换，而是删除并重新创建了我的表，数据类型设置为BIGINT（8）。

我从我的SQL语句中删除了铸件，错误消失了。

去图..........

SQLCODE：-420，SQLSTATE：22018，SQLERRMC：BIGINT
