Hi,
I know that there is a callback that can be called when a column is
updated. But it doesn't give a bitmap of the columns changed
/*
** Register a callback to be invoked each time a row is updated,
** inserted or deleted using this database connection.
*/
SQLITE_API void *sqlite3_update_hook(
sqlite3 *db, /* Attach the hook to this database */
void (*xCallback)(void*,int,char const *,char const *,sqlite_int64),
void *pArg /* Argument to the function */
){
void *pRet;
sqlite3_mutex_enter(db->mutex);
pRet = db->pUpdateArg;
db->xUpdateCallback = xCallback;
db->pUpdateArg = pArg;
sqlite3_mutex_leave(db->mutex);
return pRet;
}
I tried to find when this function is called in the sqlite3.c . But I
didn't find it ...
Is that possible ?
The other solution is to compare old values and new values ... but I don't
think this is the best way .... .
Thx,
