## Detailed Description

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.

## Member Function Documentation

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.

Parameters

  stmt | A statement to add to batch's statements list.

Glib::RefPtr<Batch> Gnome::Gda::Batch::copy | ( |  | ) |

Copy constructor.

Returns
  A the new copy of orig.

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`.

Parameters

  out_params | A place to store a new Gda::Set object, or `0`.

Returns
  `true` if no error occurred.

StatementVector Gnome::Gda::Batch::get_statements | ( |  | ) | const

Get a list of the Gda::Statement objects contained in batch.

Returns
  A list of Gda::Statement which should not be modified.

static GType Gnome::Gda::Batch::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

GdaBatch* Gnome::Gda::Batch::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GdaBatch* Gnome::Gda::Batch::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

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.

Parameters

  stmt | A statement to remove from batch's statements list.

Glib::ustring Gnome::Gda::Batch::serialize | ( |  | ) | const

Creates a string representing the contents of batch.

Returns
  A string containing the serialized version of batch.

Glib::SignalProxy1< void,Glib::RefPtr<Statement> > Gnome::Gda::Batch::signal_changed | ( |  | ) |

Slot Prototype:
  `void on_my_changed(Glib::RefPtr<Statement> stmt)`

## Friends And Related Function Documentation

Glib::RefPtr< Gnome::Gda::Batch > wrap | ( | GdaBatch * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

A Glib::wrap() method for this object.

Parameters

  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.

Returns
  A C++ instance that wraps this C instance.
