Parameterizing file name in MYSQL LOAD DATA INFILE

Question

Is there a way to dynamically specify a file name in the LOAD DATA INFILE? Can it be parameterized like for instance (syntax may be incorrect) LOAD DATA INFILE \'$filename\'

Answer 1

Or you can make a temporary copy of the file (BATCH example):

LOAD_DATA.bat

COPY %1 TempFileToLoad.csv
mysql --user=myuser --password=mypass MyDatabase < ScriptLoadMyDatabase.sql
DEL TempFileToLoad.csv

the SQL (for info) :

ScriptLoadMyDatabase.sql

load data infile 'TempFileToLoad.csv' IGNORE
into table tLoad
FIELDS TERMINATED BY ';' OPTIONALLY ENCLOSED BY '"'
lines terminated by '\r\n'
IGNORE 1 LINES
(@DateCrea, NomClient, PrenomClient, TypeMvt, @Montant, NumeroClient)
set DateCrea = str_to_date(@DateCrea, '%Y-%m-%d'), Montant = (round(@Montant / 1000)*2) ;

And finished to put a link to the BAT file in SendTo windows folder.

A citation from MySQL documentation:

The LOAD DATA INFILE statement reads rows from a text file into a table at a very high speed. The file name must be given as a literal string.

That means that it can not be a parameter of a prepared statement. But no one forbids to make the string interpolation while the statement is just a string in your PHP code.

If you're asking if it can be used in a script; you can do some thing like this with php:

<?php
$mysqli = new mysqli("host", "user", "pwd", "db");
/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}


$sql = "CREATE TABLE number1 (id INT PRIMARY KEY auto_increment,data TEXT)";
if ($result = $mysqli->query($sql)) {
} else {
printf("<br>%s",$mysqli->error);

}

$host  = $_SERVER['HTTP_HOST'];
$uri   = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');
$filename = "data.csv";

$sql = "LOAD DATA LOCAL INFILE '$host$uri$filename' INTO TABLE number1";
if ($result = $mysqli->query($sql)) {

} else {
printf("<br>%s",$mysqli->error);    
}
// Close the DB connection
$mysqli->close();

exit;
%>

If the file is in the same folder as the script just use $filename a instead of $host$uri$filename. I put this together quick from a couple scripts I'm using, sorry if it doesn't work without debug, but it should be pretty close. It requires mysqli.

Unfortunately, this feature is not yet supported in MySQL and is currently listed as bug/feature request #39115 http://bugs.mysql.com/bug.php?id=39115
