Java MS SQL Select inside Insert - java

I want to insert 5 datas into one SQL table, the last four of which are already working and fine, but the first one should be from another table, a String, giving an Int to the table in which im inserting it. And this is my solution so far. However i'm still getting an error:
"The index 5 is out of range."
PreparedStatement stmt = connection.prepareStatement("INSERT INTO RECORDS (LocationId, RecId, RecValues, YearTime, HourTime) VALUES " +
"((SELECT LocationId from Locations where Location_name = 'Mic HR1'), ?, ?, ?, ?)");
stmt.setInt(1,1);
stmt.setInt(2, recid);
stmt.setInt(3, inputData);
stmt.setDate(4, sqlDate);
stmt.setTime(5, Time.valueOf(dtf.format(now)));
stmt.executeUpdate();

Actually you have only four parameters defined on your query, because LocationId is being calculated by the inner select you provided. That's why you are getting the error.
Try this:
PreparedStatement stmt = connection.prepareStatement("INSERT INTO RECORDS (LocationId, RecId, RecValues, YearTime, HourTime) VALUES " +
"((SELECT LocationId from Locations where Location_name = 'Mic HR1'), ?, ?, ?, ?)");
stmt.setInt(1, recid);
stmt.setInt(2, inputData);
stmt.setDate(3, sqlDate);
stmt.setTime(4, Time.valueOf(dtf.format(now)));
stmt.executeUpdate();

how to execute 2 queries together?

I am working on a project and I want to insert into 2 different tables, so I wrote those 2 queries (query1, query2), when i run the program with just one query i don't get any exceptions but when executing together i have a bunch of exceptions, i used preparedStatement execute() and didn't work
note : im not very experienced please explain easily
private void loadBusesToDB() throws SQLException{
Connection connection = connect();
String query = "INSERT INTO Bus (nomLigne, Marque, Matricule, Capacite)"
+ "VALUES (?, ?, ?, ?)";
String query2 = "INSERT INTO Lignes (nomLigne, Sntv Depart, SNTV Arrive, prix)"
+ "VALUES (?, ?, ?, ?)";
PreparedStatement ps = null;
PreparedStatement ps2 = null;
try {
ps = connection.prepareStatement(query);
ps2 = connection.prepareStatement(query2);
for(Bus bus : Bus.buses){
ps.setString(1, bus.getNomLigne());
ps.setString(2, bus.getMarque());
ps.setString(3, bus.getMatricule());
ps.setInt(4, bus.getCapacite());
ps.addBatch(); // THE INSERT HAPPENS HERE
}
ps.executeBatch();
for(Lignes ligne : Lignes.lignes){
ps2.setString(1, ligne.getNomLigne());
ps2.setString(2, ligne.getDepart());
ps2.setString(3, ligne.getArrive());
ps2.setFloat(4, ligne.getPrix());
ps2.addBatch(); // THE INSERT HAPPENS HERE
}
ps2.executeBatch();
} catch (SQLException ex) {
ex.printStackTrace();
System.out.println("ERROR HERE");
throw ex;
}finally{
ps.close();
ps2.close();
connection.close();
}
}
Error:

As #uaraven points out, you have a syntax error regarding column names in the second query. In SQL, any identifier (including table, column, stored procedures, functions, etc.) with spaces or special characters/symbols in their names or names match reserved words need to be escaped when referenced in any clause (SELECT,FROM, JOIN, WHERE, GROUP BY, HAVING, ORDER BY ).
Now, different RDBMS's handle such escaping differently. Consider the following depending on your database. SQLite may be the only RDBMS that includes all.
Double Quotes (ANSI-SQL standard) (Oracle, DB2, Postgres, RedShift, Teradata, SQLite, with added rules of capitalization for some; SQL Server/MySQL does support with mode changes)
String query2 = "INSERT INTO Lignes (nomLigne, \"SNTV DEPART\", \"SNTV ARRIVE\", prix)"
+ " VALUES (?, ?, ?, ?)";
Square Brackets (SQL Server, Sybase, SQLite, MS Access)
String query2 = "INSERT INTO Lignes (nomLigne, [Sntv Depart], [SNTV Arrive], prix)"
+ " VALUES (?, ?, ?, ?)";
Backticks (MySQL, MariaDB, Google BigQuery Standard SQL, SQLite, MS Access)
String query2 = "INSERT INTO Lignes (nomLigne, `Sntv Depart`, `SNTV Arrive`, prix)"
+ " VALUES (?, ?, ?, ?)";

MySQL INSERT INTO doesn't work but gives no error

I'm having trouble inserting a row into a MySQL table with Java. I'm not sure what the problem is as it isn't giving an error. I'm trying to insert the row with the following:
String sql = "INSERT INTO users (uuid, authKey, code, scratches) VALUES (?, ?, ?, ?);";
PreparedStatement insertStmt = connection.prepareStatement(sql);
insertStmt.setString(1, uuid);
insertStmt.setString(2, key);
insertStmt.setInt(3, code);
insertStmt.setString(4, getScratchString());
insertStmt.executeUpdate();
The table 'users' is created successfully with no errors with the following:
Statement stmt = connection.createStatement();
stmt.executeUpdate("CREATE TABLE IF NOT EXISTS users (uuid VARCHAR(40), authKey VARCHAR(30), code INT(10), scratches VARCHAR(45));");
When trying to insert the row with the same update in phpmyadmin, it works fine. There is no error given by the update so I have no idea where to start debugging. Any help would be appreciated. Thanks.
You have to do commit transaction check the below code
String sql = "INSERT INTO users (uuid, authKey, code, scratches) VALUES (?, ?, ?, ?)";
PreparedStatement insertStmt = connection.prepareStatement(sql);
insertStmt.setString(1, uuid);
insertStmt.setString(2, key);
insertStmt.setInt(3, code);
insertStmt.setString(4, getScratchString());
insertStmt.executeUpdate();
connection.commit();

Java/MySQL - Retrieve ID from last record saved

Can anyone help me out please? I am trying to retrieve ID(primary key) at the time the record is created and set it to a textfield. Currently, all it returns is 1 all the time.
My current approach looks like this:
connection = Utilities.getConnection();
String sqlQuery = "INSERT INTO student_details (Name, Surname, Date_Of_Birth, Gender, Address, Post_Code, Mobile_Number)" + " VALUES (?, ?, ?, ?, ?, ?, ?)";
preparedStatement = connection.prepareStatement(sqlQuery);
preparedStatement.setString(1, txtFirstName.getText().trim());
preparedStatement.setString(2, txtSurname.getText().trim());
preparedStatement.setString(3, String.valueOf(dpDateOfBirth.getValue()));
preparedStatement.setString(4, cbGender.getSelectionModel().getSelectedItem().toString());
preparedStatement.setString(5, txtAddress.getText().trim());
preparedStatement.setString(6, txtPostCode.getText().trim());
preparedStatement.setString(7, txtMobileNo.getText().trim());
preparedStatement.executeUpdate();
txtStudentID.setText(String.valueOf(preparedStatement.RETURN_GENERATED_KEYS));
Utilities.showInforMsg("Record Saved:", "Record has been saved.");
You should get the generated key via:
ResultSet rs = preparedStatement.getGeneratedKeys();
if (rs.next()) {
key = rs.getLong(1);
}
what you are doing with this line
txtStudentID.setText(String.valueOf(preparedStatement.RETURN_GENERATED_KEYS));
is setting the student id to the value of the constant of the Statement interface (see here https://docs.oracle.com/javase/7/docs/api/java/sql/Statement.html#RETURN_GENERATED_KEYS)

Java variable not saving in database

I want to store six variables 3 are integers and three are of string data type, here is my prepared statement code
PreparedStatement stmt = connection.prepareStatement("insert into mydb (firstInt, firstString, secondString, secondInt, thirdInt, thirdString ) values (?, ?, ?, ?, ?, ?)");
stmt.setInt(1, firstInt);
stmt.setString(2, firstString);
stmt.setString(3, secondString);
stmt.setInt(4, secondInt);
stmt.setInt(5, thirdInt);
stmt.setString(6, thirdString);
stmt.executeUpdate();
The problem is string and integer type variables are not storing in database. What is wrong with this code?
May be you are not committing the transaction and autocommit might be set as false at database level. Please check your code and db settings.

Unable to insert a row in Oracle with Java (JDBC) --> error ORA-00917: missing comma

I have a problem during an insert in Oracle using Java and JDBC. The error obtained is:
java.sql.SQLException: ORA-00917: missing comma
The data for the insert is taken from a form like a string and is parsed to the appropiated data type and then is saved in an object called edicio. That's all OK. Then, my intention is make an insert in the DB using the data of this object.
Here is the code of the DAO, where I'm making the insert:
public Edicio insertarCurs(Connection con, Edicio ed) throws SQLException {
PreparedStatement stm = null;
ResultSet rst = null;
// Insert
StringBuffer sql = new StringBuffer();
sql.append("INSERT INTO curs (id, nom, idarea, area, programa, datainici)");
sql.append(" VALUES (?, ?, ?, ?, ?, ?");
logger.info("Building insert works fine.");
try {
stm = con.prepareStatement(sql.toString());
// params
stm.setLong(1, ed.getIdEdicio());
stm.setString(2, ed.getNomEdicio());
stm.setLong(3, ed.getIdArea());
stm.setString(4, ed.getArea());
stm.setString(5, ed.getPrograma());
// Conversion from Java Date to SQL Date
java.sql.Date sqlDate = new java.sql.Date(ed.getDataInici().getTime());
logger.info("sqlDate before the insert is: "+ sqlDate); //0011-12-02
stm.setDate(6, sqlDate);
// Data and results commented
logger.info("Id edicio: "+ ed.getIdEdicio()); //6
logger.info("Nom edicio: "+ ed.getNomEdicio()); //test
logger.info("Id area: "+ ed.getIdArea()); //0
logger.info("Nom area: "+ ed.getArea()); //test
logger.info("Programa: "+ ed.getPrograma()); //test
logger.info("Data inici: "+ sqlDate); //2011-06-06
// We are going to execute the insert
int numRows = stm.executeUpdate();
// The program never reaches this point, fails doing the executeUpdate()
logger.info("Rows created: "+ numFiles);
...
The variable types are:
idEdicio = long
nomEdicio = String
idArea = long
area = String
programa = String
dataInici = Date
Can someone help me? Thank you in advance :)
Missing )
sql.append(" VALUES (?, ?, ?, ?, ?, ?");
should be
sql.append(" VALUES (?, ?, ?, ?, ?, ?)");
sql.append(" VALUES (?, ?, ?, ?, ?, ?)");
^--- missing parenthesis
