Database directories are located directly under the data directory : MySQL LOAD Command
Load data from a text file to table

LOAD DATA INFILE 'mytbl.txt' INTO TABLE mytbl; LOAD DATA INFILE 'yourFolder/mytbl.txt' INTO TABLE mytbl;
The syntax of LOAD DATA is as follows:
LOAD DATA [loadoptions] INFILE 'filename.txt' [duplicateoptions] INTO TABLE tablename [importoptions] [IGNORE ignorenr LINES] [(columnlist)] LOAD DATA INFILE 'c:/import1-latin1.txt' INTO TABLE importtable1 FIELDS TERMINATED BY '\t' ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' LOAD DATA INFILE '/tmp/import2.txt' REPLACE INTO TABLE importtable2 FIELDS ENCLOSED BY '\"'
The LOAD DATA INFILE Statement
LOAD DATA INFILE 'file_name' INTO TABLE table_name; LOAD DATA INFILE '/var/mysql/data/test/data.txt' INTO TABLE t;
LOAD DATA assumes the columns in the datafile have the same order as the columns in the table.
mysql> LOAD DATA LOCAL INFILE 'mytbl.txt' INTO TABLE mytbl (b, c, a);
Load a file that has data values separated by commas, and lines ending with carriage returns
shell> mysqlimport --fields-terminated-by=,--lines-terminated-by="\r" world City.txt
Load a datafile containing values quoted by double quote characters
shell> mysqlimport --fields-terminated-by='"' world City.txt
Use LOAD DATA to load a file into a database other than the current one, you can qualify the table name with the database name.
mysql> LOAD DATA LOCAL 'mytbl.txt' INTO TABLE other_db.mytbl;
