[Freeswitch-users] Spidermonkey ODBC

[David Revill]

I spotted this error a few months ago, and to my shame did not let everyone know.  I have since archived the project so cannot point you to the actual code. However, the problem is  that it assumes the name of the Firebird Driver (FB64?)  to set a boolean, so that it handle the connection test differently.

When looking at the actual code, I actually felt that the connection test was redundant, as all it did was a select from a system table. This meant it was doing two queries for everyone required. (One to see if it could do a query, and then one to do it). I therefore commented the connection test function out.

regards

  Hi,

  I'm experimenting with spidermonkey for JavaScript call control, the basics seem fine and I'm now trying to connect to an existing Firebird database, the Firebird odbc lib is installed ok as is unixODBC and I can confirm this and access the db no problem with isql, something strange happens though when I connect in spidermonkey, basically the odbc connection is made successfully, but then as soon as I call either exec or query the odbc connection starts to drop and re-connect continuously, 

  the isql output is below 

  isql -v test
  +---------------------------------------+
  | Connected!                            |
  |                                       |
  | sql-statement                         |
  | help [tablename]                      |
  | quit                                  |
  |                                       |
  +---------------------------------------+
  SQL> select first 1 * from pool_phones
  +---------------------+------------+
  | GSMNO               | ORGNO      |
  +---------------------+------------+
  | 0712345678         | 1          |
  +---------------------+------------+
  SQLRowCount returns 1
  1 rows fetched
  SQL>

  however the following test code calling the same query

  use("ODBC");
  var db = new ODBC("test","SYSDBA","masterkey");
  db.connect();
  db.query("select first 1 *  from pool_phones");
  db.nextRow();
  row = db.getData();
  console_log("INFO","HELLO " +  row["GSMNO"]  + "\n");
  exit();

  gives the following output and then just loops disconnecting and reconnecting until I shutdown freeswitch

  Any ideas much appreciated

  Thanks
