[gnome-db] gda_xml_database

[Rui Barreiros <ruiba mail telepac pt>]

Hi there,

i've downloaded gnomedb and gda, and i'm trying to create a xml db using
default provider, here is the code:

  GdaXmlDatabase *db;
  GdaTable *table;
  GdaFieldAttributes *fa;

  db = gda_xml_database_new();
  gda_xml_database_set_name(db, "ngCatalog");
  gda_xml_database_set_uri(db, "URI=/tmp/catalogDB.db2");

  table = gda_xml_database_new_table(db, "teste");

  fa = gda_field_attributes_new();
  gda_field_attributes_set_name(fa, "id");
  gda_field_attributes_set_gdatype(fa, GDA_VALUE_TYPE_INTEGER);
  gda_field_attributes_set_caption(fa, "Id");
  gda_field_attributes_set_defined_size(fa, 30);
  gda_field_attributes_set_allow_null(fa, 0);
  gda_field_attributes_set_primary_key(fa, 1);
  gda_field_attributes_set_unique_key(fa, 1);
  gda_field_attributes_set_auto_increment(fa, 1);

  gda_table_add_field(table, (const GdaFieldAttributes *)fa);
  gda_field_attributes_free(fa);

  gda_xml_database_save(db, "/tmp/catalogDB.db2");

as there is no documentation (examples and such) about xml db, i tried
using the api documentation, and it seem's to work well this way but
when i run my app it send this errors:

(ngcataloghome:7758): GLib-GObject-WARNING **: invalid cast from
`GdaTable' to `GdaDataModelArray'

** (ngcataloghome:7758): CRITICAL **: file gda-data-model-array.c: line
236 (gda_data_model_array_set_n_columns): assertion
`GDA_IS_DATA_MODEL_ARRAY (model)' failed

** (ngcataloghome:7758): CRITICAL **: file gda-data-model.c: line 259
(gda_data_model_get_n_columns): assertion `CLASS (model)->get_n_columns
!= NULL' failed

and it just creates a filename with the database and table definition
without any column. it seems it won't cast the GdaTable to
GdaDataModelArray in gda-table.c on gda_table_add_field function thus
not adding the field, and gives the error of the no columns.

Another doubt, wy is the file created with the following perms?

--wxrwx--T    1 brandon  brandon        82 Dec 23 20:40
/tmp/catalogDB.db2

this way, not even the owner (in this case the user brandon) can't read
the file.

Best wishes,

Rui Barreiros
