How to make sql insert string from data entered into JTextField

im having some problems getting the insert string to work its giving me a syntax error but cant figure out why, any help ?
String sql = "INSERT INTO user VALUES ('"+ jtfEmailAddr.getText()+"'," +
"'"+ jtfPassword2.getText() + "'," +
"'"+ jtfFName.getText() +"','" + jtfSurname.getText() +"')" +
"ON DUPLICATE KEY UPDATE password='" + jtfPassword2.getText() + "'"+ `enter code here`
"firstname='" + jtfFName.getText() + "'," +
"lastname='" + jtfSurname.getText() + "'";
database.insertIntoDatabase(sql);
ERROR:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'rr'nn)' at line 1
the letters rr nn are just random for test purposed

Try adding a comma there “‘,”
With no more information is the part I see wrong
(Apart from of course the the “enter code here”...)

INSERT INTO with embedded apostrophe

Eclipse neon.1 (4.6.1) java;
SQLite 3.8.7 (sqlite-jdbc-3.8.7.jar)
I am attempting to insert customer's data into a table using the following code snippet:
PreparedStatement ps;
insertSQL = "INSERT INTO tbl_TotalPatent "
+ "(Abstract, `Application/Filing Date`, `Application Number`) "
+ "VALUES ("
+ "'" + _field[0] + "', "
+ "'" + _field[1] + "', "
+ "'" + _field[2] + "');";
ps = con.prepareStatement(insertSQL);
ps.execute();
Unfortunately, the client's data has an embedded apostrophe, which I cannot change. The "INSERT INTO" statement bombs out when finding the apostrophe, assuming it is a single quote:
java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (near "s": syntax error)
I've tried various permutations of the INSERT INTO statement to use different characters for the single quote - to no avail.
I presume there is an "easy" work-around, but I can't find it. The solution is probably posted somewhere on stackoverflow, but I can't find it. Can someone point me in the right direction?

you can replace that apostrophe with an double apostrophe, which is the standard SQL escape sequence for '
simply do that whith the following snippet:
+ "'" + _field[x].replaceAll("'", "''") + "', "
You could also use " instead of ' in your sql statement like the following:
+ "\"" + _field[x] + "\", "

What is wrong with this QUERY, why it is giving me following error?

I'm learning swing in java. I've make a jtable that is populated by database's values (sql table --> user(id, name, age)). I want to make jtable that is if i change values from jtable is should also update database on click on button. but where i query is executed an error occurs. I want to know what is issue with this query ???
QUERY:
String sql = "UPDATE \'alarm bell marshal\' SET mr = \'" + mrs.get(row) +
"\' , shop = \'" +shops.get(row)+ "\' where id = \'" + ids.get(row) + "\'";
ERROR:
SEVERE: null
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''alarm bell marshal' SET mr = '0' , shop = '0' where id = '1'' at line 1

try use something how that:
String sql = 'UPDATE `alarm bell marshal` SET `mr` = "' + mrs.get(row) + '" , `shop` = "' + shops.get(row) + '" WHERE `id` = "' + ids.get(row) + '"';

Exception while input a date into a MySQL database

I have a MySQL database and want to write a row into it. The problem is that MySQL do not like my query, why? This is my code:
java.sql.Timestamp date = new java.sql.Timestamp(new java.util.Date().getTime());
for (Integer articlevalue : articlesendlist) {
for (Integer suppliervalue : suppliersendlist) {
connection.executeQuery("INSERT INTO Bestellungen(Bestellung_ID, Artikel_ID, Lieferant_ID, Datum, Preis) VALUES (" + maxorder + ", " + articlevalue + ", " + suppliervalue + ", " + date + ", NULL)");
}
}
A small description for my code. The articlesendlist contains IDs from selected values from a JTabel. The same applies to the suppliersendlist. I want to write the IDs into the table "Bestellung". The variable maxorder is the current ID for the table "Bestellung".
If you need it, the exception is:
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near '12:45:06.164, NULL)' at line 1
Please do not comment/answer with other links, I already searched for the problem and read several sites. They do not help me or are not suitable for my problem.
Thank you for help

Exception is obvious isn't it.
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near '12:45:06.164, NULL)' at line 1
You are not using quotes around date field.
However you should really avoid executing your SQL queries like this and use PreparedStatemens for this purpose.
PreparedStatemens has specific methods like setDate, setTime, setLong, setString etc and you don't need to worry about putting right quotes in your code.

Try changing this line:
connection.executeQuery("INSERT INTO Bestellungen(Bestellung_ID, Artikel_ID, Lieferant_ID, Datum, Preis) VALUES (" + maxorder + ", " + articlevalue + ", " + suppliervalue + ", " + date + ", NULL)");
to this:
connection.executeQuery("INSERT INTO Bestellungen(Bestellung_ID, Artikel_ID, Lieferant_ID, Datum, Preis) VALUES ('" + maxorder + "','" + articlevalue + "','" + suppliervalue + "','" + date + "','NULL')");

MySQL query error from Java

I've got the following query in my Java code. But when I run it, it says a syntax error in the query.
What am I doing wrong here?
"Inset into department ( dept_name, dept_desc ) values ('" + deptName + "','" + deptDesc + "')"

Its INSERT not Inset . This is a simple typo. Replace the word.
"Inset into department ( dept_name, dept_desc ) values ('" + deptName + "','" + deptDesc + "')"
^^^^^^

For future reference, as a beginner, using an SQL formatter might help point out the error for nagging issues like these.
