Mysql – Import CSV file into Mysql with Multiple Delimiters/Field Separators

Since you are not allowed to script but SQL try the following:

CREATE TABLE importweirddata( txt varchar(255) ) ENGINE=MyISAM;
LOAD DATA LOCAL INFILE 'whatever_importfile.txt'
INTO TABLE importweirddata
LINES TERMINATED BY '\r\n';
UPDATE importweirddata SET txt = REPLACE(txt,'\"\"','\"');
SELECT * FROM importweirddata INTO 'improved_importfile.txt';
DROP TABLE importweirddata;

There you go, another text file that has the doubled double quotes stripped.

If you want all doubled double quotes replaced with single quotes, do this UPDATE:

CREATE TABLE importweirddata( txt varchar(255) ) ENGINE=MyISAM;
LOAD DATA LOCAL INFILE 'whatever_importfile.txt'
INTO TABLE importweirddata
LINES TERMINATED BY '\r\n';
UPDATE importweirddata SET txt = REPLACE(txt,'\"\"','\'');
SELECT * FROM importweirddata INTO 'improved_importfile.txt';
DROP TABLE importweirddata;

Now, go import that file (improved_importfile.txt) and have fun with it.

Give it a Try !!!

The easiest solution would be to write a small script that reads that file and executes some queries to import these data sets.

If you want to use PHP (just one example, more information here) it would be something like:

    <?php

    $db = new PDO($connectStr, $username, $password);
    $q = $db->prepare("INSERT INTO table (...) VALUES (...)");

    $file = file_get_contents(...);
    $lines = explode("\n", $file);

    foreach ($lines as $line) {
        $data = explode(";", $line);
        // manipulate password here, for PHP, use password_hash instead of md5
        $q->execute([$data]);
    }
    ?>

Another promising solution could be LOAD DATA INFILE. You should have a look at http://dev.mysql.com/doc/refman/5.1/en/load-data.html for more information.
