For backups produced with mysqldump --tab, each table is represented in the output directory by an .sql file containing the CREATE TABLE statement for the table, and a .txt file containing the table data. To reload a table, first change ___location into the output directory. Then process the .sql file with mysql to create an empty table and process the .txt file to load the data into the table:

$> mysql db1 < t1.sql
$> mysqlimport db1 t1.txt

An alternative to using mysqlimport to load the data file is to use the LOAD DATA statement from within the mysql client:

mysql> USE db1;
mysql> LOAD DATA INFILE 't1.txt' INTO TABLE t1;

If you used any data-formatting options with mysqldump when you initially dumped the table, you must use the same options with mysqlimport or LOAD DATA to ensure proper interpretation of the data file contents:

$> mysqlimport --fields-terminated-by=,
         --fields-enclosed-by='"' --lines-terminated-by=0x0d0a db1 t1.txt

Or:

mysql> USE db1;
mysql> LOAD DATA INFILE 't1.txt' INTO TABLE t1
       FIELDS TERMINATED BY ',' FIELDS ENCLOSED BY '"'
       LINES TERMINATED BY '\r\n';
