Glib::RefPtr< Gnome::Gda::Batch > | wrap (GdaBatch* object, bool take_copy=false) |
A Glib::wrap() method for this object. |
Multiple SQL statements grouped together.
The Gda::Batch object represents one or more SQL statements (as Gda::Statement objects) in a single object. A Gda::Batch can either be built "manually" by assembling together several Gda::Statement objects, or from an SQL string using a Gda::SqlParser object.

void Gnome::Gda::Batch::add_statement | ( | const Glib::RefPtr< Statement >& | stmt ) |
Add stmt to the list of statements managed by batch.
A Gda::Statement object can be added multiple times to a Gda::Batch object.
stmt | A statement to add to batch's statements list. |
Glib::RefPtr<Batch> Gnome::Gda::Batch::copy | ( | ) |
Copy constructor.
static Glib::RefPtr<Batch> Gnome::Gda::Batch::create | ( | ) | [static] |
bool Gnome::Gda::Batch::get_parameters | ( | Glib::RefPtr< Set >& | out_params ) |
Get a new Gda::Set object which groups all the execution parameters which stmt needs.
This new object is returned though out_params.
Note that if stmt does not need any parameter, then out_params is set to 0
.
out_params | A place to store a new Gda::Set object, or 0 . |
true
if no error occurred. StatementSList Gnome::Gda::Batch::get_statements | ( | ) | const |
Get a list of the Gda::Statement objects contained in batch.
const GdaBatch* Gnome::Gda::Batch::gobj | ( | ) | const [inline] |
Provides access to the underlying C GObject.
Reimplemented from Glib::ObjectBase.
GdaBatch* Gnome::Gda::Batch::gobj | ( | ) | [inline] |
Provides access to the underlying C GObject.
Reimplemented from Glib::ObjectBase.
GdaBatch* Gnome::Gda::Batch::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
void Gnome::Gda::Batch::remove_statement | ( | const Glib::RefPtr< Statement >& | stmt ) |
Removes stmt from the list of statements managed by batch.
If stmt is present several times in batch's statements' list, then only the first one is removed.
stmt | A statement to remove from batch's statements list. |
Glib::ustring Gnome::Gda::Batch::serialize | ( | ) | const |

object | The C instance. |
take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
