Using java to input SQL Query with backslash

Question

I have a java program which connects to a database in Oracle SQL Developer. I need data from the database to export to a .csv file. I can do this directly in SQL Developer using spooling as shown

spool D:\fileLocation\fileName.csv
select /*csv*/ * from Table;
spool off

I need to be able to input that to SQL Developer FROM the java program. I can input a query from java to sql using code below

Statement SumLevel = connection.createStatement();
    try{
        SumLevel.executeQuery("SQL Query");
        System.out.println("Succesfuly Entered Data");

    }catch(SQLException e){
        System.out.println(e);
    }finally{
        if(CompareLevel != null){
            CompareLevel.close();
        }
    }

Obviously the \\ in java is not just a character so if I try the first line of the spooling in java it will try to do \\f which is a separate function.

Using \\\\ prints out the desired code but when it inputs into sql it says there is an error "java.sql.SQLSyntaxErrorException: ORA-00900: invalid SQL statement". I believe this is due to SQL reading the code showing \\\\ rather than \\

spool D:\\fileLocatoin\\fileName.csv
select /*csv*/ * from Table;
spool off

How would I be able to input the sql spooling code into a java program.

Thanks

Answer 1

Short answer You can't run spool command from Java .

Explanation.

Java is not connects to Oracle SQL Developer it connects to Oracle database. Oracle database can run SQL queries.

spool command is not part of SQL . It is command of Oracle SQL Developer command language.

Solution

Either you run your SQL query ( select * from Table , note that it doesn't allow comment in it) and then process result and write to file using some CSV lib.

Or you continue to use Oracle SQL Developer tool.
