GdaSelect

struct GdaSelectPrivate

struct GdaSelectPrivate;

gda_select_new ()

GdaDataModel* gda_select_new                (void);

Create a new GdaSelect object, which allows programs to filter GdaDataModel's based on a given SQL SELECT command..

A GdaSelect is just another GdaDataModel-based class, so it can be used in the same way any other data model class is.

gda_select_add_source ()

void        gda_select_add_source           (GdaSelect *sel,
                                             const gchar *name,
                                             const GdaDataModel *source);

Add a data model as a source of data for the GdaSelect object. When the select object is run (via gda_select_run), it will parse the SQL and get the required data from the source data models.

gda_select_set_sql ()

void        gda_select_set_sql              (GdaSelect *sel,
                                             const gchar *sql);

Set the SQL command to be used on the given GdaSelect object for filtering rows from the source data model (which is set with gda_select_set_source).

gda_select_run ()

gboolean    gda_select_run                  (GdaSelect *sel);

Run the query and fill in the GdaSelect object with the rows that matched the SQL command (which can be set with gda_select_set_sql) associated with this GdaSelect object.

After calling this function, if everything is successful, the GdaSelect object will contain the matched rows, which can then be accessed like a normal GdaDataModel.
