PDO and Blob type with sqlite

[peacemoon]

 

 

i store blob data with php like this

 

$this->_db->exec"CREATE TABLE media (url TEXT, content BLOB)");

 

$fp = fopen($encoded['path'], 'rb');

$sql = "INSERT INTO media (url, content) VALUES (?, ?)";

$stmt = $this->_db->prepare($sql);

$stmt->bindValue(1, $encoded['url'], PDO::PARAM_STR);

$stmt->bindValue(2, $fp, PDO::PARAM_LOB);

$stmt->execute();

fclose($fp);

 

And in my c++ program (using bada framework) i read the data from blob column back. The problem is, when i use php on my localhost (version 5.3.2-1ubuntu4.2), my c++ app can recognize the blob column as blob type correctly. But when i use my remote host (php version 5.2.12) to create sqlite file, my c++ app recognizes the blob column as TEXT TYPE and my binary data is corrupted.

 

Does anyone know why and any work around?

 

Thanks

SQLite's data types are very different to that of other databases. You in fact don't even need to declare data types for anything other than auto incrementing fields (which must be declared as INTEGER).

 

I suspect this could be the cause of your problems, unfortunately, I don't offer any solution however. You should read the Sqlite docs for further info, its been a long while since of read them.

i suspect there is problem with PDO of PHP, because my c++ programm could read data succesfully from the file i created on my localhost. Just want to ask whether someone have encountered the same problem and found any work around.
