odbc_errormsg — Get the last error message
Returns a string containing the last ODBC error message, or an empty string if there has been no errors.
   If odbc is specified, the last state
   of that connection is returned, else the last state of any connection
   is returned.
  
   This function returns meaningful value only if last odbc query failed
   (i.e. odbc_exec() returned false).
