When you create a
CSV table, the server creates a
table format file in the database directory. The file begins with
the table name and has an
.frm extension. The
storage engine also creates a data file. Its name begins with the
table name and has a
.CSV extension. The data
file is a plain text file. When you store data into the table, the
storage engine saves it into the data file in comma-separated values
CREATE TABLE test (i INT NOT NULL, c CHAR(10) NOT NULL)->
ENGINE = CSV;Query OK, 0 rows affected (0.12 sec) mysql>
INSERT INTO test VALUES(1,'record one'),(2,'record two');Query OK, 2 rows affected (0.00 sec) Records: 2 Duplicates: 0 Warnings: 0 mysql>
SELECT * FROM test;+------+------------+ | i | c | +------+------------+ | 1 | record one | | 2 | record two | +------+------------+ 2 rows in set (0.00 sec)
If you examine the
test.CSV file in the
database directory created by executing the preceding statements,
its contents should look like this:
"1","record one" "2","record two"
This format can be read, and even written, by spreadsheet applications such as Microsoft Excel or StarOffice Calc.
CSV storage engine does not support indexing.
