How to use mysql command LOAD DATA INFILE with PreparedStatement? [duplicate]

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'?

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.

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

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.

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.

Accessing data in an object array with Java

I'm currently working with Cucumber and Java. I would like to retrieve that path of a file from ITestResult.
I'm currently retrieving the parameters with:
Object[] test = testResult.getParameters();
However the only thing I can access would seem the be the first objects name and nothing else.
test = {Object[1]#1492}
0 = {CucumberFeatureWrapper#1493} "Links at EDM Documents View,"
cucumberFeature = {CucumberFeature#1516}
path = "test/01-automation.feature"
feature = {Feature#1518}
cucumberBackground = null
currentStepContainer = {CucumberScenario#1519}
cucumberTagStatements = {ArrayList#1520} size = 1
i18n = {I18n#1521}
currentScenarioOutline = null
I cannot see anyway of retrieving path = "test/01-automation.feature" under cucumber feature.

Have you tried something like ((CucumberFeatureWrapper)test[0]).getCucumberFeature().getPath()?

Select with a set of predefined values in JOOQ for PostgreSQL

Does anybody know is it possible to write in JOOQ select with a set of predefined values? I need it for insert if not exists.
For example,
INSERT INTO test
(text)
SELECT '1234567890123456789'
WHERE
NOT EXISTS (
SELECT id FROM test WHERE text = '1234567890123456789'
);

I've found the answer by myself:
List<Param<?>> params = new LinkedList<>();
params.add(DSL.val("1234567890123456789"));
List<Field<?>> fields = new LinkedList<>();
fields.add(TEST.TEXT);
SelectConditionStep<Record1<TEXT>> notExistsSelect = context.select(TEST.TEXT).from(TEST).where(TEST.TEXT.eq("1234567890123456789"));
SelectConditionStep<Record> insertIntoSelect = context.select(params).whereNotExists(notExistsSelect);
context.insertInto(TEST, fields).select(insertIntoSelect).execute();
But it would be great, if we had an ability to do it via InsertQuery. I've not found the way to do it.

How to export data from Cassandra to CSV file using Java

I tried to use the DataStax Java Driver, but then i found out it does not support the COPY command, does anyone know other methods of exporting data using Java? Thanks.

For example i have created event table:
cqlsh:kunderatest> describe TABLE event ;
CREATE TABLE event (
id text,
log text,
timstamp bigint,
PRIMARY KEY (id)
)
and inserted three record
cqlsh:kunderatest> INSERT INTO event (id, log , timstamp ) VALUES ( '1', 'my first log' , 12345678);
cqlsh:kunderatest> INSERT INTO event (id, log , timstamp ) VALUES ( '2', 'my second log' , 12345679);
cqlsh:kunderatest> INSERT INTO event (id, log , timstamp ) VALUES ( '3', 'my third log' , 12345680);
1) First you can do it by using CQLSH client. Now you can export the data of event table into any file (in this case it is log.txt) by executing following command.
cqlsh:kunderatest> COPY kunderatest.sample (id, name, age, address) TO './log.txt' WITH DELIMITER = '|' AND QUOTE = '''' AND ESCAPE = '''' AND NULL = '<null>';
3 rows exported in 0.042 seconds.
You can validate the command output by verify log.txt file. Hope it will help you.
2) Second you can also use Runtime utility of Java to execute the export command in order to achieve the goal.
create a file (let say command.txt) and paste the following export command into that file.
COPY kunderatest.sample (id, name, age, address) TO './log.txt' WITH DELIMITER = '|' AND QUOTE = '''' AND ESCAPE = '''' AND NULL = '<null>'
after creating the file and adding the above command into that file do the following it will export the data into file which is given in export command.
String exportCommand = cassandraHome + "bin/cqlsh " + hostname + " " + rpcPort + " -f command.txt"; // file which holds export command
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec(exoprtCommand);
// for keep tracking the log, you can do following.
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ((line = br.readLine()) != null)
{
}
Note: cassandrahome is path of cassandra package directory. in my case it is /usr/local/apache-cassandra-2.0.6

Whitespaces in Java/PHP

Spaces not changing to underscored when sent from Java-->PHP-->SQL
Java code:
String urlString = "http://www.mysite.com/auth/verifyuser.php?name="+name.toLowerCase().replace(" ","_");
PHP code:
$name = mysql_real_escape_string($_GET['name']);
$name = str_replace(' ', '_', $name);
$query = "select * from authinfo where name LIKE '$name'";
mysql_query($query);
$num = mysql_affected_rows();
if ($num > 0) {
echo '1';
} else {
echo '0';
}
when I implement a test log on the SQL database, it somehow still seems to show up with spaces instead of underscores(even though I replace it in Java and PHP) and the PHP file returns '0' rather than '1'. I've heard the issue might be whitespaces? It seems to happen to only certain users, mostly mac users.

If your php file is returning a 0, that means your query is not getting executed. Where are you establishing a connection with the database before executing the query?

Remark: where name = '$name'
mysql_affected_rows concerns INSERT, UPDATE and DELETE.
$r = mysql_query($query);
$num = mysql_num_rows($r);

It's unsafe to pass raw name into URL without encoding it.
String urlString = "http://www.example.com/auth/verifyuser.php?name=" + URLEncoder.encode(name.toLowerCase(), "UTF-8");
In PHP you can obtain data:
$name = urldecode($_GET['name']);
