客户有个数据库从HP平台迁移到linux平台,字符集相同。impdp的时候报错ORA-01401了。

不仅仅是在导表结构+数据的时候报错,单独导metadata的时候,也报上面的错。
正常情况下,ORA-01401是因为做insert时,字段长度过长。如定义字段是varchar2(10),插入了11个字符,从而报错。
而impdp报错ORA-01401往往是因为字符集的问题,可以参考ORA-01401 / ORA-12899 / ORA-01461 While Importing Or Loading Data In An AL32UTF8 / UTF8 (Unicode) Or Other Multibyte NLS_CHARACTERSET Database. (Doc ID 1297961.1)。
但是客户的这个数据库源和目标字符集都完全一致。且用csscan检查,也没发现报错。
为啥客户的这个库,甚至还没导数据,在导metadata的时候就报错ORA-01401了呢?
进一步检查,终于发现了问题所在。这个表的定义,通过metadata.get_ddl看到:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
DBMS_METADATA.GET_DDL('TABLE','ASS_ACCHSHT_GREEN_MEMORY','MYORDATA') -------------------------------------------------------------------------------- CREATE TABLE "MYORDATA"."ASS_ACCHSHT_GREEN_MEMORY" ( "GREEN_ID" VARCHAR2(16) NOT NULL ENABLE, "ACCOUNT_ID" VARCHAR2(16) NOT NULL ENABLE, "ADDED_BY" VARCHAR2(100), "ADDED_DATE" VARCHAR2(16) DEFAULT sysdate ) SEGMENT CREATION IMMEDIATE PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING STORAGE(INITIAL 65536 NEXT 1048576 MIN EXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT) TABLESPACE "MYORDATA" |
注意这里第9行, “ADDED_DATE” VARCHAR2(16) DEFAULT sysdate。而其实sysdate是要19个字符的:
1 2 3 4 5 6 7 |
SQL> select length(sysdate),lengthb(sysdate) from dual; LENGTH(SYSDATE) LENGTHB(SYSDATE) --------------- ---------------- 19 19 SQL> |
所以这里的表定义是错误的,既然有default sysdate,那么字段类型应该是date型。如果定义成varchar2(16),那么录入的是字符型,不应该带上default sysdate。

^_^,那它一定是定义
export NLS_DATE_FORMAT=’YYYYMMDDHH24:MI:SS’
SCOTT@book> select length(sysdate),lengthb(sysdate) from dual;
LENGTH(SYSDATE) LENGTHB(SYSDATE)

不然不可能以前ok的。
对,你说的没错。^_^
