MYSQL to ORACLE blob migration issue

Question

Hi
I am currently migrating a mysql schema to Oracle. I have used the SQLDeveloper Migration Workbench to generate the scripts to capture the data and to upload the data to oracle.
However I have an issue with one particular table (which contains blob data). Note: Other tables with blob data have been successfully migrated.
This is the command I am using to load the data.
sqlldr cms/cms control=Oracle\cms.user_key.ctl log=cms.user_key.logThis is the sqlfile specifying the table structure.
load data
infile 'user_key.txt'
"str '<EORD>'"
into table cms.user_key
fields terminated by '<EOFD>'
trailing nullcols
USER_KEY_ID  NULLIF USER_KEY_ID = 'NULL' ,
KEY_SIZE  NULLIF KEY_SIZE = 'NULL',
PUBLIC_EXPONENT  NULLIF PUBLIC_EXPONENT = 'NULL' ,
CERTIFICATE_AUTHORITY_ID  NULLIF CERTIFICATE_AUTHORITY_ID = 'NULL',
VALIDITY "TO_DATE(DECODE(:VALIDITY, 'NULL', NULL, :VALIDITY),  'yyyy-mm-dd HH24:mi:ss')" ,
STATUS  NULLIF STATUS = 'NULL' ,
GENERATION_DATE "TO_DATE(DECODE(:GENERATION_DATE, 'NULL', NULL, :GENERATION_DATE),  'yyyy-mm-dd HH24:mi:ss')" ,
CERTIFICATE     char(2000000000) NULLIF CERTIFICATE = 'NULL',
PROFILE_CERT_ID  NULLIF PROFILE_CERT_ID = 'NULL' ,
PERSON_ID  NULLIF PERSON_ID = 'NULL' ,
SUPPORT_ID  NULLIF SUPPORT_ID = 'NULL' ,
SERIAL_NUMBER CHAR(255) "DECODE(:SERIAL_NUMBER, 'NULL', NULL, NULL, ' ', :SERIAL_NUMBER)" ,
REQUEST_ID  NULLIF REQUEST_ID = 'NULL' ,
KEY_USAGE CHAR(255) "DECODE(:KEY_USAGE, 'NULL', NULL, NULL, ' ', :KEY_USAGE)"
)This is the statement to create the table I am migrating into
CREATE TABLE user_key (
  USER_KEY_ID NUMBER(24,0) NOT NULL,
  KEY_SIZE NUMBER(10,0),
  PUBLIC_EXPONENT NUMBER(10,0),
  CERTIFICATE_AUTHORITY_ID NUMBER(24,0),
  VALIDITY DATE,
  STATUS NUMBER(10,0),
  GENERATION_DATE DATE,
  CERTIFICATE BLOB,
  PROFILE_CERT_ID NUMBER(24,0) DEFAULT '0' NOT NULL,
  PERSON_ID NUMBER(24,0),
  SUPPORT_ID NUMBER(24,0),
  SERIAL_NUMBER VARCHAR2(255 CHAR),
  REQUEST_ID NUMBER(10,0),
  KEY_USAGE VARCHAR2(255 CHAR)
);If I change the support_id and request_id into varchar2(255) datatypes the data loads but I can see some data is loaded into the wrong column.
When the datatypes are correct, the data starts to get loaded but exits after 50 errors, and tye log file complains that I am trying to put non-numeric data into a numeric field.
Can any one shed somnme light on this problem

Answer 1

Problem was setting the characterset. Needed to be UTF8 for blobs but for other data needed to be WE8MSWIN1252.
