what do you mean by Scanning error when parsing

i am getting the following error while inserting bulk records....why we will get this error and how to rectify it?

    Scanning error before 'name`,`username`...' when parsing: INSERT INTO temporary_employee_data

PHQL does not allow dot-commas (sic) in statements ;

By dot-commas Andre meant semicolons

That error is generated by Phalcon when it's trying to convert your PHQL statement into SQL. Something in your query is broken. Paste it here so we can see the full query.
