8.9. The CSV Storage EngineThe CSV storage engine stores data in text files using comma-separated values format. To enable this storage engine, use the --with-csv-storage-engine option to configure when you build MySQL. The CSV storage engine is included in MySQL-Max binary distributions. To enable this storage engine if you build MySQL from source, invoke configure with the --with-csv-storage-engine option. To examine the source for the CSV engine, look in the sql/examples directory of a MySQL source distribution. 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 format. mysql> CREATE TABLE test(i INT, c CHAR(10)) 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" The CSV storage engine does not support indexing. |
