let's say i am trying to save an image selected from photo library to database..is the following code correct?
Snap.m
- (void) addSnap {
if(addStmt == nil) {
const char *sql = "insert into Snap(snapTitle, snapDesc, snapImage) Values(?, ?, ?)";
if(sqlite3_prepare_v2(database, sql, -1, &addStmt, NULL) != SQLITE_OK)
NSAssert1(0, @"Error while creating add statement. '%s'", sqlite3_errmsg(database));
}
sqlite3_bind_text(addStmt, 1, [snapTitle UTF8String], -1, SQLITE_TRANSIENT);//bind titleSnap to insert statement
sqlite3_bind_text(addStmt, 2, [snapDescription UTF8String], -2, SQLITE_TRANSIENT);
sqlite3_bind_int(addStmt, 3, snapID);
NSData *imgData = UIImagePNGRepresentation(self.snapImage);
int returnValue = -1;
if(self.snapImage != nil)
returnValue = sqlite3_bind_blob(addStmt, 3, [imgData bytes], [imgData length], SQLITE_TRANSIENT);
else
returnValue = sqlite3_bind_blob(addStmt, 3, nil, -1, NULL);
sqlite3_bind_int(addStmt, 4, snapID);
if(returnValue != SQLITE_OK)
NSLog(@"Not OK!!!");
if(SQLITE_DONE != sqlite3_step(addStmt))//execute step statement if it return SQLITE_DONE
NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database));
else
//sqlite3_last_insert_rowid
snapID = sqlite3_last_insert_rowid(database);//get primary key for the row which was inserted
//reset add statement
sqlite3_reset(addStmt);
}
- (void)setSnapImage:(UIImageView *)theSnapImage {
self.isDirty = YES;
[snapImage release];
snapImage = [theSnapImage copy];
}
then to get the "object" i use..
snap2playObj.snapImage = imageView.image;
i am using UIImageView by the way..my error message..
