into the table, the storage engine saves it into the data file in
comma-separated values format.
CREATE TABLE test (i INT NOT NULL, c CHAR(10) NOT NULL)->

test.CSV file in the
database directory created by executing the preceding statements,

"1","record one" "2","record two"
This format can be read, and even written, by spreadsheet applications such as Microsoft Excel or StarOffice Calc.
