SQL & PL/SQL

Hello Every one,

I am trying to execute the following SQL :

insert into  RES_HIST_TEMP

(

  PACKAGE_ID,

  PARTNERID,

  TREATMENT,

  TREATMENT_VAL,

  RESPONSE_SK,

  RESP_DDTM,

  RESP_DT,

  RESP_INFO_D1,

  RESP_INFO_D2)

select PACKAGE_ID,

       PARTNERID,

       1001,

       'S',

       900000005,

       to_timestamp("DATE",'YYYY-MM-DD HH24:MI:SS'),

       "DATE",

       CODE,

       DEV_TYPE||' '||DEVICE_OS  

from RESP_KONT_VIEW

where  type <> 'send'

       and  seq_no = 1881111

I got  an error ORA-00904 :"RESP_DDTM"  Invalid Identifier

RESP_DDTM is not null  Timestamp(6) in table

How can I resolve this error?

BR,

Mohammed
