Re: [gnome-db] Alternative to "gda_prepare_create_table" not using variable arguments ?

[Daniel Espinosa <esodan gmail com>]

I can write a new function as follow:

 gda_connection_prepare_create_table_from_list (GdaConnection *cnn, const gchar *table_name, GSList *fields, GError **error)

GSList *list - could hold a new data structure like:

typedef {
     gchar  *field_name, // Filed's name
    GType  field_type,  // Field's type
    GdaEasyCreateTableFlag flag, // a tag
    GSList tag_arguments // Tag's arguments like for                  GDA_EASY_CREATE_TABLE_FKEY_FLAG
} GdaCreateTable

What do you think?

And May deprecate gda_prepare_create_table for a new gda_connection_prepare_create_table

No, there is not: the gda_prepare_create_table() and associated
similar functions are for a quick and easy usage of Libgda's basic
tasks, but for a better control, you'll have to use the
GdaServerOperation objects direclty. To simplify this, you can use the
actual implementation of gda_prepare_create_table() as a starting
point.
