Question

i hv a code & it doesn't work,i dnt know y.
this is my code:
public void set_level(int lvl)
     System.out.println("level = "+ lvl);
try {
     statement = connection.createStatement();
    ResultSet r= statement.executeQuery("select level from User");
     boolean success=r.next();
  if (success==true)
      statement.executeUpdate("UPDATE User SET level="+lvl);
     statement.close();
  else
    System.out.println("Error with the level");
}//try
    catch ( Exception e )
         e.printStackTrace();
     }//catch
}//end function set_levelthis code should b called to update the column level in my DB,the column level has only 1 record,the parameter level that is passed has the right value,but there's a problem with the update statement. when i get an error during executing the code,it refers to the next function,and this error:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] The LEVEL clause includes a reserved word or argument that is misspelled or missing, or the punctuation is incorrect.
So cud u plz tell me what's wrong?

Answer 1

Just in case what I said wasn't clear. Level is a word that means something to your SQL engine. Just like SELECT or UPDATE.
You can't have a query like
SELECT * FROM mytable WHERE SELECT=?
or like
SELECT * FROM UPDATE
And you can't use level either. Same problem.
