BufferedWriter bw = new BufferedWriter(new FileWriter( "test.ctl ",false));
bw.write( "load data\r\n ");
bw.write( "infile 'test.txt '\r\n ");
bw.write( "truncate into table test\r\n ");
bw.write( "fields terminated by ', ' enclosed by '\ " '\r\n ");
bw.write( "trailing nullcols\r\n ");
bw.write( "(id,name)\r\n ");
