Types 如何在使用sql loader时将带有时区的时间戳转换为仅时间戳

我面临的错误如下：

enter code here

       load data
         infile '/u01/app/oracle/scripts/Elite_export.csv'
         discardfile '/u01/app/oracle/scripts/data.dis'
         into table TBLRADIUSCUSTOMER_TEST
         fields terminated by ","
        ( 
USERNAME ,
PASSWORD ,
CUSTOMERSTATUS ,
CONCURRENTLOGINPOLICY ,
RADIUSPOLICY ,
ADDITIONALPOLICY ,
PARAM1 ,
PARAM2 ,
PARAM3 ,
PARAM4 ,
CUSTOMERTYPE ,
CALLINGSTATIONID ,
CUI ,
MACVALIDATION ,
IMSI ,
MEID ,
MSISDN ,
MDN ,
GEOLOCATION ,
CREATEDATE  "TO_TIMESTAMP(:CREATEDATE,'DD-MM-YY HH24:MI:SS.ff')",
LASTMODIFIEDDATE "TO_TIMESTAMP(:LASTMODIFIEDDATE,'DD-MM-YY HH24:MI:SS.ff')"
  )

使用SQL Loader将数据类型从带区域的时间戳更改为时间戳时需要帮助（6）

请建议我如何在将数据加载到Oracle表时放弃时区详细信息

如果您不关心时间戳，只需要日期中的数字，放弃时区信息，请使用substr放弃时区信息：

     Record 1: Rejected - Error on table TBLRADIUSCUSTOMER_TEST, column CREATEDATE.
     ORA-01830: date format picture ends before converting entire input string

     Record 2: Rejected - Error on table TBLRADIUSCUSTOMER_TEST, column CREATEDATE.
      ORA-01830: date format picture ends before converting entire input string


     and so on.....

Substr以“DD-MM-YY HH24:MI:SS.ff”格式获取日期部分

CREATEDATE  "TO_TIMESTAMP(SUBSTR(instr(:CREATEDATE, ' ', 10),1,24),'DD-MM-YY HH24:MI:SS.ff')",

---

日期和时区信息之间的分隔符位置。我假设数字和tz信息之间会有一个空格，所以我使用17作为instr的起始位置，在'DD-MM-YY HH24:MI:SS'日期部分之后找到第一个空格。

感谢有价值的响应，我使用简单的SUBSTR函数实现了相同的结果：斜体粗体

CREATEDATE“SUBSTR（：CREATEDATE，1,31）”，

instr(:CREATEDATE, ' ', 17)
