3, using the select into ...... outfile kc export table data, export file name kc1.txt, required fields separated by commas, character field value in double quotes, each rows with "->" at the beginning, end of each line carriage return line;

4, create a table structure identical kc create table like Table kc1 use statement, using load data to import data kc1.txt kc1 table, it is required to import data is ignored preceding three records, only introduction course name, course number credits three columns of data;
