SQL Loader is the utility to use for high performance data loads. 

The SQL Loader control file contains information that describes how the data will be loaded ,Which contains the table name, column datatypes, field delimiters, etc.

See example:

$more account_data.csv

8,"DZcLHm6H2iDNnvjU7TafFA==","53746a61-aeaa-4856-ba52-932fbb6b8161","nZAylFNJOOY=","DZcLHm6H2iDNnvjU7TafFA==",0,"2010-08-12",90,1
9,"5nBoqMWLF+w=","53746a61-aeaa-4856-ba52-932fbb6b8190","vpluH45reHw=","QS9PWc3XtBY83LkgSkGJJA==",0,"2010-08-12",90,1

 $ more account.ctl
OPTIONS(BINDSIZE=8388608,READSIZE=8388608,ERRORS=-1,ROWS=1)
LOAD DATA
INFILE '/henry/account_data.csv'
APPEND INTO TABLE account
FIELDS TERMINATED BY ',' Optionally enclosed by '"'
(
id ,
  field3 ,
  field4  ,
  field2  ,
  field1  ,
  field5 ,
  field6 date 'yyyy-mm-dd',
  field7  ,

)

then run the command from bash:

sqlldr userid=pv/pv  control=account_data.ctl log=account_data.log

view account_data.log
