Karl Wright commented on CONNECTORS-1032:
-----------------------------------------

If that looks right, can you modify:

connectors/jdbc/connector/src/main/java/jdbc/JDBCConnection.java, at about line 503, from this:

{code}
      // We have 'colcount' cols to look thru
      for (int i = 0; i < resultCols.length; i++)
      {
        String key = resultCols[i];
{code}

... to this:

{code}
      // We have 'colcount' cols to look thru
      System.out.println("Number of columns: "+resultCols.length);
      for (int i = 0; i < resultCols.length; i++)
      {
        String key = resultCols[i];
        System.out.println("Key = "+key);
{code}

> Against some indeterminate version of MySQL, the seeding query:
> {code}
> SELECT command_id AS $(IDCOLUMN) FROM icinga_commands
> {code}
> ... produces the following:
> Error: Bad seed query; doesn't return $(IDCOLUMN) column. Try using quotes around $(IDCOLUMN) variable, e.g. "$(IDCOLUMN)".
> So does:
> {code}
> SELECT command_id AS "$(IDCOLUMN)" FROM icinga_commands
> {code}
> The first level of diagnosis will be to determine what column names are in fact being returned.  IDynamicResultRow has the following method:
> {code}
>  public Iterator<String> getColumns();
> {code}
> ... which we will need to use to get at the column names.
