Hello Simon,
Code looks like this:
/* move content */
sqlite3_backup *pBackup;
pBackup = sqlite3_backup_init(destDBHandle, "main", sourceDBHandle,
"main");
if(pBackup)
{
int sqlErrno;
if ((sqlErrno = sqlite3_backup_step(pBackup, -1)) != SQLITE_DONE)
{
Tr_Err("SwapDB sqlite3_backup_step sqlErrno %d", sqlErrno);
result = false;
}
if ((sqlErrno = sqlite3_backup_finish(pBackup)) != SQLITE_OK)
{
Tr_Err("SwapDB sqlite3_backup_finish sqlErrno %d", sqlErrno);
result = false;
}
}
else
{
Tr_Err("SwapDB could not be init");
result = false;
}
