Question

I am trying to insert data from Netezza to Oracle.Here are my inserts as below.But they don’t work and throw me the above error.

INSERT INTO AM_CTL_DDS_LOAD values('ALB',1002,'2012/02/12');
INSERT INTO AM_CTL_DDS_LOAD values('ALB',1002,'2012/02/09');
INSERT INTO AM_CTL_DDS_LOAD values('ALB',1002,'2012/02/21');
INSERT INTO AM_CTL_DDS_LOAD values('ALB',1002,'2012/02/23');

My table structure is as below.

CREATE TABLE AM_CTL_DDS_LOAD
(
    MAS_DIV_CD VARCHAR(5),
    LD_SEQ_NBR INTEGER NOT NULL,
    TUNING_DT DATE NOT NULL
);

Answer 1

The ORA-01861: literal does not match format string error implies that the third column of the AM_CTL_DDS_LOAD table is defined as a DATE, not a VARCHAR2, and that the implicit conversion of the string to a date is failing because your session’s NLS_DATE_FORMAT isn’t ‘YYYY/MM/DD’. The best way to solve the problem is to explicitly insert a DATE rather than a VARCHAR2 by explicitly calling TO_DATE with an appropriate format mask.

INSERT INTO AM_CTL_DDS_LOAD values('ALB',1002,to_date('2012/02/12', 'YYYY/MM/DD') );
INSERT INTO AM_CTL_DDS_LOAD values('ALB',1002,to_date('2012/02/09', 'YYYY/MM/DD') );
INSERT INTO AM_CTL_DDS_LOAD values('ALB',1002,to_date('2012/02/21', 'YYYY/MM/DD') );
INSERT INTO AM_CTL_DDS_LOAD values('ALB',1002,to_date('2012/02/23', 'YYYY/MM/DD') );
