Open DB in documents folder - ios

I have an sqlite file in my documents folder (I cheched and it's there). The issue is that the function openDatabase always prints Yes, even if I give it wrong path, so this is wierd.
The second thing is
if (sqlite3_prepare_v2(localDB,query_stmt, -1, &statement, NULL) == SQLITE_OK)
it always goes to else and print "Error on SQLITE_OK". Can you please help me with my code:
#interface SQLReader ()
{
sqlite3 *localDB;
}
#end
#implementation SQLReader
- (void)viewDidLoad {
[super viewDidLoad];
[self openDatabase];
sqlite3_stmt *statement;
NSString *querySQL = #"SELECT * FROM Animations";
const char *query_stmt = [querySQL UTF8String];
if (sqlite3_prepare_v2(localDB,query_stmt, -1, &statement, NULL) == SQLITE_OK)
{
if (sqlite3_step(statement) == SQLITE_ROW)
{
NSString *addressField = [[NSString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement, 0)];
NSString *phoneField = [[NSString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement, 1)];
NSLog(#"%#",addressField);
NSLog(#"%#",phoneField);
}
else
{
NSLog(#"%s","Match not found");
}
sqlite3_finalize(statement);
}
else
{
NSLog(#"%s","Error on SQLITE_OK");
}
}
- (void)openDatabase
{
NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
char *dbpath = (char *)[[documentsPath stringByAppendingPathComponent: #"Bemad/IR_World/DB/IRRMobile.sqlite"] UTF8String];
BOOL openDatabaseResult = sqlite3_open(dbpath, &localDB);
NSLog(openDatabaseResult ? #"DB: Yes" : #"DB: No");

sqlite error database is locked
(8 answers)
Closed 6 years ago.
I am getting error Database Locked.
at first attempt it adds the row but after that i am getting the error
database locked.
I am trying to make web page saver so at first time when app loads it is adding the row but when again I try to save any webpage it is not saving and I am getting the error database locked.
Even the deletion is also not happening after saving one web page.

You can only access sqllite once at a time. If you have multiple threads, you can run in this situation. Example:
So always try to close database once it is used using:
sqlite3_close(database);
You need to make sure every sqlite3_open is balanced with a sqlite3_close before trying to do sqlite3_open again:
Your saveData method has quite a few return statements that will prevent the database from ever calling sqlite3_close. Make sure all paths out of the method close the database properly. In the end, this means that you'll try to open the database although it's already open.
Or, better, just open the database once and leave it open, eliminating the repeated opening and closing of the database.
Your Delete, Fav, and removeFav methods are also not closing the database.
A few unrelated observations:
You should be wary about using stringWithFormat to build SQL with string parameters. If the string being searched for had a apostrophe in it, your code will fail. Use ? placeholders and then use sqlite3_bind_text to bind values to those placeholders.
If you make your sno column a AUTOINCREMENT, you won't have to do that "get the max sno before inserting new row" logic. Thus, the CREATE statement might look like:
create table if not exists list (
sno integer primary key autoincrement,
name text,
category text,
path text,
fav integer)
You can then omit sno from the INSERT statements, and it will automatically be assigned a unique identifier.

Closed 6 years ago.
I have used sqlite database in my app.I am doing CURD operation.I get data from json then i convert that data into arrays after that from arrays i insert the data into sqlite database.In my app when data can be upto more than 1000 records.When database is done then i get memory warning.

This is not a Database issue.
This issue is caused because Application doesn't have a storyboard for the device you are trying to run upon.

How to set results from sqlite to array NSMutableArray

HERE IS MY CODE:
NSString *ask = [NSString stringWithFormat:#"SELECT name FROM users"];
sqlite3_stmt *statement;
const char *query_statement = [ask UTF8String];
const char *dbpath = [_databasePath UTF8String];
if (sqlite3_open(dbpath, &_DB) == SQLITE_OK){
{
if (sqlite3_prepare_v2(_DB, query_statement, -1, &statement, nil) == SQLITE_OK)
{
while (sqlite3_step(statement) == SQLITE_ROW)
{
NSString *nameField = [[NSString alloc] initWithUTF8String:(const char *)sqlite3_column_text(statement, 0)];
}
sqlite3_finalize(statement);
sqlite3_close(_DB);
}
}
I want to set those result above to NSMUtableArray like this example:
totalStrings =[[NSMutableArray alloc]initWithObjects:#"xxx",#"xxx",#"xxx", nil];
What should I do ?
=================UP DATE ALL CODE =======================
Here is the aditonal code to make it easy to see. I really donĀ“t know what I have done wrong.
#interface ViewController ()
{
NSMutableArray *totalStrings;
NSMutableArray *filteredStrings;
BOOL isFiltered;
}
#property(strong, nonatomic)NSMutableArray *entries;
#end
#implementation ViewController;
#synthesize entries;
- (void)viewDidLoad {
// totalStrings =[[NSMutableArray alloc]initWithObjects:#"ggg",#"gggggg", nil];
// NSLog(#"%#",totalStrings);
NSMutableArray* result=[[NSMutableArray alloc] init];
NSString *ask = [NSString stringWithFormat:#"SELECT * FROM users"];
sqlite3_stmt *statement;
const char *query_statement = [ask UTF8String];
const char *dbpath = [_databasePath UTF8String];
if (sqlite3_open(dbpath, &_DB) == SQLITE_OK){
{
if (sqlite3_prepare_v2(_DB, query_statement, -1, &statement, nil) == SQLITE_OK)
{
while (sqlite3_step(statement) == SQLITE_ROW)
{
NSString *nameField = [[NSString alloc] initWithUTF8String:(const char *)sqlite3_column_text(statement, 0)];
//add your namefield here.
[result addObject:nameField];
totalStrings=[[NSMutableArray alloc] initWithArray:result];
}
sqlite3_finalize(statement);
sqlite3_close(_DB);
}
}
NSLog(#"%#",totalStrings);
//AND PUT THOSE RESULTS INTO THIS ARRAY ( I WILL USE THIS LATER)
//I want it to be this format: totalStrings=[[NSMutableArray alloc]initWithObjects:#"test1",#"test2",#"test3", nil];
}
The code below should work in case you want to get all namefields in array
NSMutableArray* result=[[NSMutableArray alloc] init];
NSString *ask = [NSString stringWithFormat:#"SELECT name FROM users"];
sqlite3_stmt *statement;
const char *query_statement = [ask UTF8String];
const char *dbpath = [_databasePath UTF8String];
if (sqlite3_open(dbpath, &_DB) == SQLITE_OK){
{
if (sqlite3_prepare_v2(_DB, query_statement, -1, &statement, nil) == SQLITE_OK)
{
while (sqlite3_step(statement) == SQLITE_ROW)
{
NSString *nameField = [[NSString alloc] initWithUTF8String:(const char *)sqlite3_column_text(statement, 0)];
//add your namefield here.
[result addObject:nameField];
}
sqlite3_finalize(statement);
sqlite3_close(_DB);
}
}
In the end you can do
totalStrings=[[NSMutableArray alloc] initWithArray:result];
Create and Alloc New NSMutableArray totalStrings and add nameField in the totalStrings in While Loop.
NSMutableArray *totalStrings = [[NSMutableArray alloc] init];
In while loop
[totalStrings addObject:nameField];
You can get it like this,
-(NSArray *)list_totalStrings
{
NSMutableArray *totalStrings = [[NSMutableArray alloc] init];
NSString *ask = [NSString stringWithFormat:#"SELECT name FROM users"]; //Make sure field and table names are proper
sqlite3_stmt *statement;
const char *query_statement = [ask UTF8String];
const char *dbpath = [_databasePath UTF8String];
if (sqlite3_open(dbpath, &_DB) == SQLITE_OK){
if (sqlite3_prepare_v2(_DB, query_statement, -1, &statement, nil) == SQLITE_OK)
{
while (sqlite3_step(statement) == SQLITE_ROW)
{
NSString *nameField = [[NSString alloc] initWithUTF8String:(const char *)sqlite3_column_text(statement, 0)];
[totalStrings addObject:nameField];
}
sqlite3_finalize(statement);
sqlite3_close(_DB);
NSLog(#"%#",totalStrings);
return totalStrings;
}
else
return nil;
}
else
return nil;
}

Sqlite always returns only 1 row

The count returns 3 ,as i have 3 rows in the column. But when i try to publish the name , it only returns 1 row.
please take a look at my code.
sqlite3_stmt *statement;
const char *dbpath = [_databasePath UTF8String];
if (sqlite3_open(dbpath, &_chatDB) == SQLITE_OK)
{
NSString *querySQL = [NSString stringWithFormat:
#"SELECT MESSAGE from CHATCOMPLETE"];
const char *query_stmt = [querySQL UTF8String];
if (sqlite3_prepare_v2(_chatDB,
query_stmt, -1, &statement, NULL) == SQLITE_OK)
{
if (sqlite3_step(statement) == SQLITE_ROW)
{
NSString *name = [[NSString alloc] initWithUTF8String:
(const char *) sqlite3_column_text(statement, 0)];
NSLog(#"Name is %#",name);
}
}
else{
NSLog(#"Not found");
// return nil;
}
sqlite3_reset(statement);
}
}
Change your if/else to a while to step through all the rows:
while (sqlite3_step(statement) == SQLITE_ROW) {
NSString *name = [[NSString alloc] initWithUTF8String:
(const char *) sqlite3_column_text(statement, 0)];
NSLog(#"Name is %#",name);
}
Then you can process all of the results.
And you should change sqlite3_reset to sqlite3_finalize. And don't forget to close the database too.

Error no such table in iphone sqlite select query?

I am having tabbed iPhone application.In the first tab I created sqlite table and inserted values to the table,these are done successfully.In the second tab I am able to get the values from table but in third class when I am executing the select query, I am getting the no such table exception.
