Answer 1

Где

sqlite3_open([databasePath UTF8String], &database);?

Вы не можете работать с закрытой базой данных.

Answer 2

-(BOOL)insertDatabaseValue:(SignIn *)objFavourie isUpdate:(BOOL)update
{

BOOL returnValue = YES;
sqlite3_stmt *insertStmt = nil;
sqlite3  *database = nil;

if (sqlite3_config(SQLITE_CONFIG_SERIALIZED) == SQLITE_OK){
    returnValue = NO;
}



if (sqlite3_open([DataBasePath UTF8String], &database) == SQLITE_OK){



    if(insertStmt == nil) {
        NSString *aString;
        if(!update)
            aString =[NSString stringWithFormat:@"INSERT INTO Sanjay('Name', 'Password') Values(?, ?)"];

        else 
            aString =[NSString stringWithFormat:@"UPDATE Sanjay SET Password = ? where 'Name'=%@",objFavourie.strName]; 


        const char *sql = [aString UTF8String];

        if(sqlite3_prepare_v2(database, sql, -1, &insertStmt, NULL) != SQLITE_OK)
        {
            NSLog(@"Error while creating insert :%s add statement.", sqlite3_errmsg(database));
            returnValue = NO;
        }
    }
    if(sqlite3_bind_text(insertStmt, 1, [objFavourie.strName UTF8String], -1, SQLITE_TRANSIENT) != SQLITE_OK){
        returnValue = NO;
    }
    if(sqlite3_bind_text(insertStmt, 2, [objFavourie.strPassword UTF8String], -1, SQLITE_TRANSIENT) != SQLITE_OK) {
        returnValue = NO;
    }

    if(SQLITE_DONE != sqlite3_step(insertStmt)){
        NSLog(@"Error while inserting into '%s'", sqlite3_errmsg(database)); 
        returnValue = NO;
    }
    sqlite3_reset(insertStmt);    


    if (insertStmt) {
        sqlite3_finalize(insertStmt);
        insertStmt = nil;
    }

    sqlite3_close(database);
    database = nil;
}
else {
    returnValue = NO;
}

return returnValue;
