  • Where does the 'method' implementation go? (I'm a newbie)

    - by Spokane-Dude
    I have this code: #import "SQLiteDB.h" @implementation SQLiteDB @synthesize db, dbPath, databaseKey; @end //-------------- check for database or create it ----------------| - (void)checkForDatabase { NSFileManager *filemanager = [NSFileManager defaultManager]; NSString *databasePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingString:@"/ppcipher.s3db"]; if(![filemanager fileExistsAtPath:databasePath]) { //Database doesn't exist yet, so we create it... NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingString:@"/ppcipher.s3db"]; sqlite3 *db; if(sqlite3_open(databasePath, db) == SQLITE_OK) { } } } It's complaining that "method definition not in @implementation context". So where does it go? (I tried in the .h file, but still get the error)

  • Create a (edit) hyperlink in front of dropdownbox with jQuery

    - by CziX
    I have a table with some data. All data is contained in dropdownboxes and textbox. But it isn't easy to see, what is newly written input and what is data from the database. So I want to create a (edit) after these boxes, and replace the boxes with a literal where the contained value in the dropdownbox stands. When the edit-button is pushed the literal goes away and the dropdownbox appears instead, so it is possible to edit the data. This is all, the jQuery don't have to save the data to database, I have functionality to that in a save-button. I don't want to use any extra plugin to jQuery, because it seems to be a fairly simpel task. Any good ideas?

  • Criteria: search for two different entity classes...

    - by RoCMe
    Hi! I have a "super entity" SuperEntity and three entities ChildEntity1, ..., ChildEntity3 which extends the super class. It's easy to search for all entities in the database, i.e. we could use session.createCriteria(SuperEntity.class); It's no problem to search for one specific entity type, too, just replace the SuperEntity with any of the children to look for entities of that type. But I have a problem when allowing 'multiple choice' for the types. I.e., it could be neccessary to search all entities of type 1 and 2, but not of type 3. A first idea was to create two independent queries and join the results in a final list - but that would destroy the paging which uses offset and limit functionality of the database... Is there a possibility in Criteria to join two different queries in one single result list? Kind regards, RoCMe

  • Best practices for storing & selecting time/date with php & mysql?

    - by Adam
    I often find myself storing data in a mysql database, and then wanting to display all sorts of stats about my data, specifically stuff like 'how many rows do I have for this date, or that date'. Does anyone know of (or could write) a good tutorial on this subject? Ideally a good tutorial would overview: Best practices when storing the data (i.e. what formats to use, how to use them servertime vs. generated time, etc.) Best practices when selecting data from the database with php (i.e. how to sort rows by date, how to retrieve only rows from a certain date, or a certain hour, etc).. Timezones and other issues that might come up. Thanks in advance.

  • Anyone plotting SO via code_swarm?

    - by Tim Post
    Is anyone working on something to render individual questions, or SO as a whole with codeswarm? If so, can you post a link to your work that transforms SO questions into revisions that codeswarm can understand (i.e. svn?) It would be really, really cool to see SO played (as a whole) via codeswarm, so I hope to not only ask if anyone is working it, but see if anyone is interested in trying to accomplish it. Augmenting that, will database dumps be made available? EDIT: Database dumps have since been made available :) Enough with user voice, is anyone doing it? If so, what VCS did you mock?

  • My $query->fetch() doesn't work

    - by Tae
    Question edited following the comments. It still doesn't work. Hi there, I'm trying to learn how PDO works, but my script: $database = new PDO('mysql:host=localhost;dbname=***', '***', '***'); $query = $database->prepare("SELECT nombre, tecnica, tamanno, estado FROM obra WHERE anno = ?"); $query->execute(array('2009')); while ($item = $query->fetch(PDO::FETCH_ASSOC)) { $item['nombre']; } Prints nothing. If I do: var_dump($query->fetch()) I get bool(false). After reading lots of examples I can't figure out what I'm doing wrong. Thanks in advance.

  • Why is one query consistently ~25ms faster than another in postgres?

    - by Emory
    A friend wrote a query with the following condition: AND ( SELECT count(1) FROM users_alerts_status uas WHERE uas.alert_id = context_alert.alert_id AND uas.user_id = 18309 AND uas.status = 'read' ) = 0 Seeing this, I suggested we change it to: AND NOT EXISTS ( SELECT 1 FROM users_alerts_status uas WHERE uas.alert_id = context_alert.alert_id AND uas.user_id = 18309 AND uas.status = 'read' ) But in testing, the first version of the query is consistently between 20 and 30ms faster (we tested after restarting the server). Conceptually, what am I missing?

  • Changing populated DataTable column data types

    - by TonE
    Hi, I have a System.Data.DataTable which is populated by reading a CSV file which sets the datatype of each column to string. I want to append the contents of the DataTable to an existing database table - currently this is done using SqlBulkCopy with the DataTable as the source. However, the column data types of the DataTable need to be changed to match the schema of the target database table, handling null values. I am not very familiar with ADO.NET so have been search for a clean way of doing this? Thanks.

  • mysql querying age from dob

    - by Confused
    My MySQL database has date of birth stored in the format yyyy-mm-dd, how do I query the database - without using php code - to show me results of people born within x years of now, and/or, who are y years of age? The table is called users, the colum is called dob. I've spent a while viewing the MySQL manual but I can't work out precisely how to form my query. So far I went for select * from users where dob... but I don't think that's the way to go.

  • Problem with a large CSV file

    - by moustafa
    I have a very large CSV file. 51427 lines to be exact. I need to import the entire file into a MySQL database, however, the script times out due to server settings and slow connection (and maybe other reasons that I am not aware of). So - I am now passing parameters START and LIMIT via address bar to import, like this: http://my.server.address/import.php?...000&limit=1000 This reads the entire CSV file into an array, and starts at line 10000 of the array and inserts into the database until it reaches line 11000, and then terminates the script. This works very nicely, however, I am not happy having to reach the entire 51427 lines of the CSV file into an array before processing. Is there not a way where I can only read the required lines into an array? That would speed things up significantly.

  • jQuery - Set selected value of all dropdowns on page

    - by Tgibson
    Hello Frieds, I have another jQuery question. For a user control with lots of database activity, I would like to use jQuery to set the selected values of all of the dropdowns to their "current" value. I want to do this to make the page appear to have finished the database call. My jQuery skill is not the best, but I believe I need to use the pageLoad(). And since each dropdown is inside of a user control I can search for those dropdowns beginning with "usrControl" $('select[id ^="usrControl"'].each(function(){ var selectedValue = $(this).val() $(this).val(selectedValue) }); Something like this is what I have in mind. Thanks

  • Expanded securityadmin

    - by user80652
    I'm aware that sysadmin is documented as the server role necessary for creating logins (SQL/Windows-integrated); nevertheless, I'm tasked to find out if there's any other server role (built-in or otherwise) that can be used. To be specific, I'm looking to setup one or two logins with access to create logins, create [database] users, assign users to [database] roles. Potentially reset passwords, but most of the logins are Windows-integrated and it's not necessary. Cannot have access to data at all, nor can these logins have rights to update tables nor create/update roles. Seems my only options so far are to set these 2 logins with securityadmin server role and for the specific databases, configure with db_securityadmin and db_accessadmin... but this configuration doesn't allow for creating logins.

  • How to handle redirections with codeigniter?

    - by SinneR
    Hi, im having problems starting a codeigniter project, the problem is that when i do something in a controller and then i want a page to display the result, an example: i have a form to add a item to the database, i get all the data in the controller and save it to database and then i want (if all went well) to redirect to the main page with a success msg, i was doing this with $this->load->view('admin', $data); the problem is that the url keeps saying admin/addItem so everytime the page gets refreshed it adds another item, now i found the: redirect('admin','refresh'); but this only helps me when i dont need to display any msg because this function dont allow to send a $data var. Any ideas? Probably this is really easy to fix but i cant find a way to handle the flow of the application the way i want, any help is apreciated. thanks ;)

  • Allow users to pull temporary data then delete table data (headers remain)?

    - by JM4
    I don't know the best way to title this question but am trying to accomplish the following goal: When a client logs into their profile, they are presented with a link to download data from an existing database in CSV format. The process works, however, I would like for this data to be 'fresh' each time they click the link so my plan was - once a user has clicked the link and downloaded the CSV file, the database table would 'erase' all of its data and start fresh (be empty) until the next set of data populated it. My EXISTING CSV creation code: <?php $host = 'localhost'; $user = 'username'; $pass = 'password'; $db = 'database'; $table = 'tablename'; $file = 'export'; $link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error()); mysql_select_db($db) or die("Can not connect."); $result = mysql_query("SHOW COLUMNS FROM ".$table.""); $i = 0; if (mysql_num_rows($result) > 0) { while ($row = mysql_fetch_assoc($result)) { $csv_output .= $row['Field'].", "; $i++; } } $csv_output .= "\n"; $values = mysql_query("SELECT * FROM ".$table.""); while ($rowr = mysql_fetch_row($values)) { for ($j=0;$j<$i;$j++) { $csv_output .= '"'.$rowr[$j].'",'; } $csv_output .= "\n"; } $filename = $file."_".date("Y-m-d",time()); header("Content-type: application/vnd.ms-excel"); header("Content-disposition: csv" . date("Y-m-d") . ".csv"); header( "Content-disposition: filename=".$filename.".csv"); print $csv_output; exit; ?> any ideas?
