Inserting Error - sql

Question

I'm trying to insert in postgresql db date, but when I'm inserting it, I'm getting this error:
Error occurred while INSERTING operation: org.postgresql.util.PSQLException: ERROR: column "text that i wrote" does not exist"
I don't understand what did I code wrong that, program tries to find column in values?
But when I try to output this table, it outputs without errors
WORKERDAO class
public static void insertWrk(String name, String post) throws SQLException, ClassNotFoundException {
//Declare a INSTERT statement
String updateStmt ="INSERT INTO worker(full_name,post)" +
"VALUES" +
"("+name+","+post+");";
//Execute INSTERT operation
try {
DBUtil.dbExecuteUpdate(updateStmt);
} catch (SQLException e) {
System.out.print("Error occurred while INSTERING Operation: " + e);
throw e;
}
}
DBUTIL class
public static void dbExecuteUpdate(String sqlStmt) throws SQLException, ClassNotFoundException {
//Declare statement as null
Statement stmt = null;
try {
//Connect to DB
dbConnect();
//Create Statement
stmt = conn.createStatement();
//Run executeUpdate operation with given sql statement
stmt.executeUpdate(sqlStmt);
} catch (SQLException e) {
System.out.println("Проблема в выполнение executeUpdate операции : " + e);
throw e;
} finally {
if (stmt != null) {
//Close statement
stmt.close();
}
//Close connection
dbDisconnect();
}
}
WorkerController Class
#FXML
private void insertWorker (ActionEvent actionEvent) throws SQLException, ClassNotFoundException {
try {
WorkerDAO.insertWrk(nameText.getText(),postCombo.getSelectionModel().getSelectedItem());
} catch (SQLException e) {
System.out.println("Problem occurred while inserting worker " + e);
throw e;
}
}

You need to put quotes around the data you're inserting:
String updateStmt ="INSERT INTO worker(full_name,post)" +
"VALUES" +
"("+name+","+post+");";
Should be:
String updateStmt ="INSERT INTO worker(full_name,post)" +
"VALUES" +
"('"+name+"',"'+post+'");";
Be aware that you're risking SQL Injection attacks using this method, see about using a parameterised insert. This site lists a bit more detail.
