JDBC - How do I 'getString' from a ResultSet if the column's name is a keyword?

Question

Whenever I try to retrieve the value for a column named "Comment" in an Access db (.mdb), It gives me the following error.

Offence: copying data
ERROR - Offence TABLE
java.sql.SQLSyntaxErrorException: ORA-00904: "Comment": invalid identifier

This is my code:

public static void copyOffenceTable()
    {
        PreparedStatement updateOffenceTypeTable  = null;

        //Set up "insert" string
        String insertString = "INSERT INTO Offence "
                + "(id, OffenceName, status, OffenceSuburb, OffenceDate, FirstName, LastName, \"Comment\", OffenderAddress, OffenderSuburb, OffenderPostcode, OffenderState, OffenderEmail, LicenceNumber, DOB, StaffIssuerID, OffenderPhone) "                                          
                + "VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";

        String MSAccessQuery = "SELECT * FROM Offence";

        try
        {
            //create a query object for MSAccess
            dbmsMSAccess.DBMSStatement = dbmsMSAccess.DBMSConnection.createStatement();
            //Query the MSAccess database for extraction
            dbmsMSAccess.DBMSResultSet = dbmsMSAccess.DBMSStatement.executeQuery(MSAccessQuery);
            //make query object for Oracle
            dbmsOracle.DBMSOracleStatement = dbmsOracle.DBMSOracleConnection.createStatement();

            dbmsOracle.DBMSOracleStatement.execute("TRUNCATE TABLE Offence");

            dbmsOracle.DBMSOracleConnection.setAutoCommit(false);

            updateOffenceTypeTable = dbmsOracle.DBMSOracleConnection.prepareStatement(insertString);

            System.out.println("Offence: copying data");

            while(dbmsMSAccess.DBMSResultSet.next())
            {
                updateOffenceTypeTable.setInt(1, dbmsMSAccess.DBMSResultSet.getInt("id") );
                updateOffenceTypeTable.setString(2, dbmsMSAccess.DBMSResultSet.getString("OffenceName") );
                updateOffenceTypeTable.setString(3, dbmsMSAccess.DBMSResultSet.getString("Status") );
                updateOffenceTypeTable.setString(4, dbmsMSAccess.DBMSResultSet.getString("OffenceSuburb") );
                updateOffenceTypeTable.setDate(5, dbmsMSAccess.DBMSResultSet.getDate("OffenceDate") );
                updateOffenceTypeTable.setString(6, dbmsMSAccess.DBMSResultSet.getString("FirstName") );
                updateOffenceTypeTable.setString(7, dbmsMSAccess.DBMSResultSet.getString("LastName") );
                updateOffenceTypeTable.setString(8, dbmsMSAccess.DBMSResultSet.getString("COMMENT") );
                updateOffenceTypeTable.setString(9, dbmsMSAccess.DBMSResultSet.getString("OffenderAddress") );
                updateOffenceTypeTable.setString(10, dbmsMSAccess.DBMSResultSet.getString("OffenderSuburb") );
                updateOffenceTypeTable.setInt(11, dbmsMSAccess.DBMSResultSet.getInt("OffenderPostcode") );
                updateOffenceTypeTable.setString(12, dbmsMSAccess.DBMSResultSet.getString("OffenderState") );
                updateOffenceTypeTable.setString(13, dbmsMSAccess.DBMSResultSet.getString("OffenderEmail") );
                updateOffenceTypeTable.setInt(14, dbmsMSAccess.DBMSResultSet.getInt("LicenceNumber") );
                updateOffenceTypeTable.setDate(15, dbmsMSAccess.DBMSResultSet.getDate("DOB") );
                updateOffenceTypeTable.setInt(16, dbmsMSAccess.DBMSResultSet.getInt("StaffIssuerID") );
                updateOffenceTypeTable.setInt(17, dbmsMSAccess.DBMSResultSet.getInt("OffenderPhone") );

                updateOffenceTypeTable.executeUpdate();
            }

            System.out.println("Offence: ACCESS DATA COPIED TO ORACLE\n");
        }
        catch(Exception X)
        {
            System.out.println("ERROR - Offence TABLE");
            X.printStackTrace();
        } 
    }

Is there a way to refer to a column that is also a keyword through jdbc?

I've tried putting 'comment' between apostrophes and also quote marks.

Any suggestions?

EDIT: The values are being placed into an oracle database with supposedly identical tables.

Answer 1

Try with some brackets:

 String insertString = "INSERT INTO Offence "
                + "(id, OffenceName, status, OffenceSuburb, OffenceDate, FirstName, LastName, [Comment], OffenderAddress, OffenderSuburb, OffenderPostcode, OffenderState, OffenderEmail, LicenceNumber, DOB, StaffIssuerID, OffenderPhone) "                                          
                + "VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";

EDIT: For oracle, if we trust this topic : https://stackoverflow.com/a/1162391/291541

The solution is the double quote but you have to pay attention to the case. Please check if your column is comment instead of Comment by example.

Answer 2

Please remove Double Quotes inside the Query

   String insertString = "INSERT INTO Offence "
                + "(id, OffenceName, status, OffenceSuburb, OffenceDate, FirstName, LastName, Comment, OffenderAddress, OffenderSuburb, OffenderPostcode, OffenderState, OffenderEmail, LicenceNumber, DOB, StaffIssuerID, OffenderPhone) "                                          
                + "VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";

Answer 3

Won't be possible to rename your column at query level? something like select comment as my_comment from blabla

You could also reach that field using its index

Answer 4

Use a back quote (or back tick) to escape the offending column's name like `\\"Comment\\"`

String insertString = "INSERT INTO Offence "
+ "(id, OffenceName, status, OffenceSuburb, OffenceDate, FirstName, LastName, `\"Comment\"`, OffenderAddress, OffenderSuburb, OffenderPostcode, OffenderState, OffenderEmail, LicenceNumber, DOB, StaffIssuerID, OffenderPhone) "                                          
+ "VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";

Answer 5

In the end, None of these methods suggested worked for me, however they were worth a shot!

I ended up having to go into the database and get permission to change the field from comment to comments.
