Answer 1

To convert string to date try to use to_date function:

insert into RT_INVOICE (VERSION, PART_ID_BROKER, EMAIL_ID, ATTACHMENT_ID, INITIAL_AMOUNT, CURRENT_AMOUNT, GROSS_AMOUNT, 
RECEIVED_DATE, COMMITTED_DATE, CREATEDDATE, UPDATEDDATE, SETTLEMENT_DATE, CURR_ISO_CODE, WQTY_CODE_CURRENT, 
BROKER_REFERENCE, CREATED_BY, ENTITY, PRODUCT, BROKER_INV_REF, ASSIGNEE, RECEIPT_DATE, TRADE_COUNT, GST_PCT, 
IS_GST_APPLIED, SOURCE_SYSTEM, DISCOUNT, MANUAL_INDICATOR, MANUAL_REFERENCE, PAYMENT_REFERENCE, QUERY_ASSIGNMENT,
Remarks, PARENT_INVO_ID, INVOICE_MONTH, ID) values (0, 40158334066, 0, 0, 22.0, 22.0, 22.0, to_date('10 October 2016', 'dd month yyyy', 'nls_date_language = american') ,
null, to_date('2016-10-10 03:51:15', 'yyyy-mm-dd hh24:mi:ss'), to_date('2016-10-10 03:51:15', 'yyyy-mm-dd hh24:mi:ss'), null, 'HKD', 'BrokerageManualReconciliationWFQueue',
'IRDOCT169694', 'bro_admin', 'PLC LONDON', 'IRD', 'wwwqqsd', '', to_date('10 October 2016', 'dd month yyyy', 'nls_date_language = american'), 0, 0.0, 'false', 'GDS', 0.0, 
'true', null, null, null, null, null, '2016-10', 13093090)

Answer 2

'10 October 2016' , '2016-10-10 03:51:15' , and '2016-10-10 03:51:15' are strings. As your columns are datetimes, as they should be, Oracle needs to convert your strings and tries this as best as it can given your current settings. It's more or less a matter of luck whether Oracle understands your formats or not.

Use ANSI datetime literals instead:

date '2016-10-10', null, timestamp '2016-10-10 03:51:15', timestamp '2016-10-10 03:51:15'
