Image not store in sqlite - ios

Question

I made one demo which stores an Image to the database. Currently I am not getting any error but my image is not store in sqlite database.
Please see the below code and tell me where is my mistake.
DBManager class
sqlite3 *sqlite3DatabaseObject;
sqlite3_stmt* sqlite3Statement;
-(void)database
{
directoryPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
documentsDirectory = [directoryPaths objectAtIndex:0];
NSString * databasePath = [[NSString alloc]initWithString:[documentsDirectory stringByAppendingPathComponent:#"informationdb.sql"]];
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:databasePath] == NO) {
const char *dbPath = [databasePath UTF8String];
if (sqlite3_open(dbPath, &sqlite3DatabaseObject)== SQLITE_OK) {
char * errorMessage;
const char *sqlite3Query = "CREATE TABLE IF NOT EXISTS PICTURES (PHOTO BLOB)";
if (sqlite3_exec(sqlite3DatabaseObject, sqlite3Query, NULL, NULL, &errorMessage)!= SQLITE_OK) {
NSLog(#"failed = %#",sqlite3DatabaseObject);
}
sqlite3_close(sqlite3DatabaseObject);
}else{
NSLog(#"failed to create database");
}
}
}
- (void) SaveImagesToSql: (NSData*) imgData {
NSString *databasePath = [[NSBundle mainBundle] pathForResource:#"informationdb" ofType:#"sql"];
const char* sqlite3Query = "INSERT INTO PICTURES (PHOTO) VALUES (?)";
int openDatabaseResult = sqlite3_open_v2([databasePath UTF8String], &sqlite3DatabaseObject, SQLITE_OPEN_READWRITE , NULL);
if (openDatabaseResult == SQLITE_OK) {
int sqlite3Prepare = sqlite3_prepare_v2(sqlite3DatabaseObject, sqlite3Query, -1, &sqlite3Statement, NULL);
if( sqlite3Prepare == SQLITE_OK ) {
sqlite3_bind_blob(sqlite3Statement, 1, [imgData bytes], [imgData length], SQLITE_TRANSIENT);
sqlite3_step(sqlite3Statement);
}
else
{
NSLog(#"Error is: %s", sqlite3_errmsg(sqlite3DatabaseObject));
}
sqlite3_finalize(sqlite3Statement);
}
else NSLog( #"Error is: %s", sqlite3_errmsg(sqlite3DatabaseObject) );
sqlite3_close(sqlite3DatabaseObject);
}
ViewController class
- (void)viewDidLoad {
[super viewDidLoad];
DBManager * dbmClass = [[DBManager alloc]init];
[dbmClass database];
imgView.userInteractionEnabled = YES;
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc]initWithTarget:self action:#selector(uploadOrCapture)];
[singleTap setNumberOfTapsRequired:1];
[imgView addGestureRecognizer:singleTap];
}
- (IBAction)btnSave:(id)sender {
DBManager*dbmClass = [[DBManager alloc]init];
NSData *imageInData = UIImagePNGRepresentation(imgView.image);
[dbmClass SaveImagesToSql:imageInData];
[self dismissViewControllerAnimated:YES completion:nil];
}
I am not able to find out the issue. It successfully executes all the code but when I download the database from device and checked, there is no image data stored.
Thanks in advance.

Answer 1

just replace this function to my code because you got wrong database path
- (void) SaveImagesToSql: (NSData*) imgData {
directoryPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
documentsDirectory = [directoryPaths objectAtIndex:0];
NSString * databasePath = [[NSString alloc]initWithString:[documentsDirectory stringByAppendingPathComponent:#"informationdb.sql"]];
const char* sqlite3Query = "INSERT INTO PICTURES (PHOTO) VALUES (?)";
int openDatabaseResult = sqlite3_open_v2([databasePath UTF8String], &sqlite3DatabaseObject, SQLITE_OPEN_READWRITE , NULL);
if (openDatabaseResult == SQLITE_OK) {
int sqlite3Prepare = sqlite3_prepare_v2(sqlite3DatabaseObject, sqlite3Query, -1, &sqlite3Statement, NULL);
if( sqlite3Prepare == SQLITE_OK ) {
sqlite3_bind_blob(sqlite3Statement, 1, [imgData bytes], [imgData length], SQLITE_TRANSIENT);
sqlite3_step(sqlite3Statement);
}
else
{
NSLog(#"Error is: %s", sqlite3_errmsg(sqlite3DatabaseObject));
}
sqlite3_finalize(sqlite3Statement);
}
else NSLog( #"Error is: %s", sqlite3_errmsg(sqlite3DatabaseObject) );
sqlite3_close(sqlite3DatabaseObject);
}
here this is database screenshot
Don't drag to database in your project.if any problem than tell me

Here How I do modify as per your use.
NSData *imageData = UIImagePNGRepresentation(imgView.image);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeStyle: NSDateFormatterShortStyle];
dateFormatter.dateFormat = #"ddMMyyyyhhmmss_SSS_a";
NSString *currentTime = [dateFormatter stringFromDate: [NSDate date]];
NSString *imageName=[NSString stringWithFormat:#"Image_%#",currentTime];
NSString *saveFilePath =[NSString stringWithFormat:#"%#.%#",imageName,#"png"]; //Store saveFilePath string to your database
NSString *localFilePath1 = [documentsDirectory stringByAppendingPathComponent:saveFilePath];
[imageData writeToFile:localFilePath1 atomically:YES];
Hope it helps you.
