Hi, I hope somebody can help me. I'm doing this project for my
school, but I'm having an error. It seems that the error is produced
when SELECT is executed. Here is the error message:
"java.lang.NullPointerException"
Here is the piece of code where the error is
generated.
try
{ stmt = con.createStatement(); rs = stmt.executeQuery(SQL); rsmd = rs.getMetaData(); column_count = rsmd.getColumnCount(); column_name = new String[column_count]; } catch (Exception e) { System.out.println(SQL + ";" + e.toString()); finalize(); } Please send me any feedback. I do not really know what is
happening. |
