Session Module C Interface
Options for sqlite3session_object_config
#define SQLITE_SESSION_OBJCONFIG_SIZE 1
#define SQLITE_SESSION_OBJCONFIG_ROWID 2
The following values may passed as the the 2nd parameter to
sqlite3session_object_config().
SQLITE_SESSION_OBJCONFIG_SIZE
This option is used to set, clear or query the flag that enables
the sqlite3session_changeset_size() API. Because it imposes some
computational overhead, this API is disabled by default. Argument
pArg must point to a value of type (int). If the value is initially
0, then the sqlite3session_changeset_size() API is disabled. If it
is greater than 0, then the same API is enabled. Or, if the initial
value is less than zero, no change is made. In all cases the (int)
variable is set to 1 if the sqlite3session_changeset_size() API is
enabled following the current call, or 0 otherwise.
It is an error (SQLITE_MISUSE) to attempt to modify this setting after
the first table has been attached to the session object.
SQLITE_SESSION_OBJCONFIG_ROWID
This option is used to set, clear or query the flag that enables
collection of data for tables with no explicit PRIMARY KEY.
Normally, tables with no explicit PRIMARY KEY are simply ignored
by the sessions module. However, if this flag is set, it behaves
as if such tables have a column "_rowid_ INTEGER PRIMARY KEY" inserted
as their leftmost columns.
It is an error (SQLITE_MISUSE) to attempt to modify this setting after
the first table has been attached to the session object.
