I am trying to read data from sqlite in Objective-C, but the result is QuestionNumber and TotalRate both is 0, can not read value from sqlite. Please helper how should I change my code?
-(void)readSqlite{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"Questiondata.db"];
NSLog(#"filePath,%#",filePath);
NSFileManager *fileManager = [NSFileManager defaultManager];
if([fileManager fileExistsAtPath:filePath]){
NSLog(#"database is exist.");
NSMutableArray *retArray = [[NSMutableArray alloc] init];
const char *dbpath = [filePath UTF8String];
if (sqlite3_open(dbpath, &_contactDB) == SQLITE_OK) {
NSLog(#"THIS IS OK");
const char *insert_stmt = "SELECT QuestionNumber, TotalRate FROM Questions WHERE QuestionNumber = 2";
sqlite3_stmt *statement;
if (sqlite3_prepare_v2(_contactDB, insert_stmt, -1, &statement, NULL) == SQLITE_OK) {
NSLog(#"SQLITE_OK");
int QuestionNumberx = sqlite3_column_int(statement, 0);
int TotalRate = sqlite3_column_int(statement, 1);
NSLog(#"QuestionNumberx %d",QuestionNumberx );
NSLog(#"TotalRate %d",TotalRate );
[retArray addObject:[NSNumber numberWithInt:QuestionNumberx]];
[retArray addObject:[NSNumber numberWithInt:TotalRate]];
NSLog(#"%s db err '%s' (%1d)", __FUNCTION__, sqlite3_errmsg(_contactDB), sqlite3_errcode(_contactDB));
NSLog(#"retArray %#",retArray );
sqlite3_finalize(statement);
}
}
}else{
NSLog(#"database is not exist.");
}
}
You never actually execute the query with sqlite3_step. You also never close the database.
The following assumes you will only get a single record back from your query:
-(void)readSqlite{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"Questiondata.db"];
NSLog(#"filePath,%#",filePath);
NSFileManager *fileManager = [NSFileManager defaultManager];
if([fileManager fileExistsAtPath:filePath]){
NSLog(#"database is exist.");
NSMutableArray *retArray = [[NSMutableArray alloc] init];
const char *dbpath = [filePath UTF8String];
if (sqlite3_open(dbpath, &_contactDB) == SQLITE_OK) {
NSLog(#"THIS IS OK");
const char *insert_stmt = "SELECT QuestionNumber, TotalRate FROM Questions WHERE QuestionNumber = 2";
sqlite3_stmt *statement;
if (sqlite3_prepare_v2(_contactDB, insert_stmt, -1, &statement, NULL) == SQLITE_OK) {
NSLog(#"SQLITE_OK");
if (sqlite3_step(statement) == SQLITE_ROW) {
int QuestionNumberx = sqlite3_column_int(statement, 0);
int TotalRate = sqlite3_column_int(statement, 1);
NSLog(#"QuestionNumberx %d",QuestionNumberx );
NSLog(#"TotalRate %d",TotalRate );
[retArray addObject:[NSNumber numberWithInt:QuestionNumberx]];
[retArray addObject:[NSNumber numberWithInt:TotalRate]];
NSLog(#"retArray %#",retArray );
}
sqlite3_finalize(statement);
} else {
NSLog(#"Unable to prepare statement: %s db err '%s' (%1d)", __FUNCTION__, sqlite3_errmsg(_contactDB), sqlite3_errcode(_contactDB));
}
sqlite3_close(_contactDB);
} else {
NSLog(#"Unable top open database.");
}
}else{
NSLog(#"database is not exist.");

Hello I have been trying to retrieve image from sql database named informationdb.sql but I am not able to,could anyone help with that.Here is my code
- (NSData*) LoadImagesFromSql
{
NSData* data = nil;

documentsDirectory = [directoryPaths objectAtIndex:0];
NSString * databasePath = [[NSString alloc]initWithString:[documentsDirectory stringByAppendingPathComponent:#"informationdb.sql"]];
int openDatabaseResult = sqlite3_open_v2([databasePath UTF8String], &sqlite3DatabaseObject, SQLITE_OPEN_READWRITE , NULL);
if (openDatabaseResult == SQLITE_OK) {
const char* sqlite3Query = "SELECT PHOTO FROM PICTURES";
int sqlite3Prepare = sqlite3_prepare_v2(sqlite3DatabaseObject, sqlite3Query, -1, &sqlite3Statement, NULL);
if( sqlite3Prepare == SQLITE_OK )
{
const char *myData = sqlite3_column_blob(sqlite3Statement, 1);
int myDataSize = sqlite3_column_bytes(sqlite3Statement, 1);
data = [NSData dataWithBytes:myData length:myDataSize];
sqlite3_step(sqlite3Statement);
}
sqlite3_finalize(sqlite3Statement);
}
sqlite3_close(sqlite3DatabaseObject);
return data;
}
Thank you.
first delete database in document directory than change all three method to my code
-(void)database
{
directoryPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
documentsDirectory = [directoryPaths objectAtIndex:0];
NSString * databasePath = [[NSString alloc]initWithString:[documentsDirectory stringByAppendingPathComponent:#"informationdb.sql"]];

}
else
{

}
else NSLog( #"Error is: %s", sqlite3_errmsg(sqlite3DatabaseObject) );

- (NSData*)LoadImagesFromSql
{
NSData* data = nil;

// else
// imgView.image = [UIImage imageWithData:imageData];

}

solved it by this:

// int i=0;

int openDatabaseResult = sqlite3_open_v2([databasePath UTF8String], &sqlite3DatabaseObject, SQLITE_OPEN_READWRITE , NULL);
if (openDatabaseResult == SQLITE_OK)
{
int sqlite3Prepare = sqlite3_prepare_v2(sqlite3DatabaseObject, [sqlite3Query UTF8String], -1, &sqlite3Statement, NULL);
if( sqlite3Prepare == SQLITE_OK )
{
while (sqlite3_step(sqlite3Statement) == SQLITE_ROW) {
const char *myData = sqlite3_column_blob(sqlite3Statement, 0);
int myDataSize = sqlite3_column_bytes(sqlite3Statement, 0);
data = [NSData dataWithBytes:myData length:myDataSize];
}
sqlite3_finalize(sqlite3Statement);
}
}
sqlite3_close(sqlite3DatabaseObject);
return data;
}
and updated viewWillAppear as :
-(void)viewWillAppear:(BOOL)animated{
dbmClass = [[DBManager alloc]init];
if (imgPic.image != nil) {
imgPic.image = nil;
}
imgPic.image = [UIImage imageWithData:[dbmClass LoadImagesFromSql]];
NSLog(#"%#",[dbmClass LoadImagesFromSql]);
}
I'm trying to add record to SQLite file but nothing happens. I get no error and in console I get that record is inserted in table #"----> RECORD INSERTED". Below you can see the code that I'm using. Please, can someone tell me how to fix this. Thanks for your time and help.

i have an problem when i select usernames the return is only one object and the table contain all of usernames how to solve this i try to select by database manager and i find that query sql statment is right

I am unable to create sqlite database in my documents directory.
Here is the code:
NSString *fileDir;
NSArray *dirPaths;
//Get the documents directory
dirPaths = NSSearchPathForDirectoriesInDomains(NSDemoApplicationDirectory, NSUserDomainMask, YES);
fileDir = [dirPaths objectAtIndex:0];
// Build the database path
databasePath = [[NSString alloc]initWithString:[fileDir stringByAppendingPathComponent:#"student.sql"]];
NSFileManager *fileMgr = [NSFileManager defaultManager];
if([fileMgr fileExistsAtPath:databasePath] == NO)
{
const char *dbPath = [databasePath UTF8String];
if (sqlite3_open(dbPath, &database) == SQLITE_OK)
{
char *errMsg;
const char *sql_stmt = "CREATE TABLE IF NOT EXISTS CONTACTS(ID INTEGER PRIMARY KEY , NAME TEXT, ADDRESS TEXT, MOBILE INTEGER)";
if (sqlite3_exec(database, sql_stmt, NULL, NULL, &errMsg) != SQLITE_OK) {
_status.text = #"Failed to create table";
}
sqlite3_close(database);
}
else
{
_status.text = #"Failed to open/create database";
}
}
I have debug the code and found that the compiler is not going under this condition.
sqlite3_open(dbPath, &database) == SQLITE_OK
I don't know what i am doing wrong.
Any help will be appreciated...
Thanks,
Check you code to get dirPath, you are getting right path or not, I used following way in my code and its working for me :
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
// dirPaths = NSSearchPathForDirectoriesInDomains(NSDemoApplicationDirectory, NSUserDomainMask,YES);
fileDir = dirPaths[0];
// Build the database path
databasePath = [[NSString alloc]initWithString:[fileDir stringByAppendingPathComponent:#"student.sqlite"]];
this is how i managed it.
DataBaseAccess.m
static sqlite3 *database=nil;
-(id)init
{
if(self=[super init])
{
self.user_data=#"user_data.db";
}
return self;
}

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:user_data];
success = [fileManager fileExistsAtPath:writableDBPath];
if (success) return;
// construct database from external ud.sql
NSString *filePath=[[NSBundle mainBundle]pathForResource:#"ud" ofType:#"sql"];
NSString *sqlStatement=[NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];
if(sqlite3_open([writableDBPath UTF8String], &database)==SQLITE_OK)
{
sqlite3_exec(database, [sqlStatement UTF8String], NULL, NULL, NULL);
sqlite3_close(database);
}
}
Your external sql file must contain the sql queries:
CREATE TABLE quantityInSubCountries (
refID INT,
quantity INT
);
CREATE TABLE quantityInSubRegions (
refID INT,
quantity INT
); ....
Hope it will help.
