I am creating a library app for personal development and would like to further my knowledge of MySql. I currently have two tables 'book' and 'category' book id title author category isbn ---- ------- ---------- ---------- ------- 1 Treasure Chest Jim Jones 1 14252637 2 Pirates Boat Sue Smith 2 88447737 3 Adventure Land Harry Jo 3 01918273 4 Winter Week Sam Dill 3 00999337 category id cat_name ---- ------- 1 Horror 2 Kids 3 Fiction 4 Science I am doing a simple search where I want to display all books (select * from book) and I would like to display all the books with their corresponding categories. This works but displays the category number instead of the category name. How can I alter these tables in such a way that the cat_name and category are joined? I tried to run a command in phpmyadmin as below however it returned an error; ALTER TABLE book ADD FOREIGN KEY (category) REFERENCES category(cat_name); error #1452 - Cannot add or update a child row: a foreign key constraint fails (`sslib`.`#sql-1ab4_1dae`, CONSTRAINT `#sql-1ab4_1dae_ibfk_1` FOREIGN KEY (`category`) REFERENCES `category` (`cat_name`)) I have been looking at foreign keys and indexes however I can't seem to make any sense of them. I am quite new to this so any help is much appreciated. Regards, J

Hi Firstly I am new to programming so go easy on me I am building a page where the user inputs text into a table called 'products'. This is the code I am using: $productname=$_POST['productname']; $productprice=$_POST['productprice']; $productpostage=$_POST['productposage']; $productquick=$_POST['productquick']; $productdescription=$_POST['productdescription']; $productdelivery=$_POST['productdelivery']; mysql_connect('localhost', 'username', 'password') or die(mysql_error()); mysql_select_db('Kanga') or die(mysql_error()); mysql_query("INSERT INTO 'product' VALUES ('$productname', '$productprice', '$productpostage', '$productquick', '$productdescription', '$productdelivery')"); print "$productname has been added to the database."; ?> When I press the submit button on the form, I get "Hello world(this is what i entered into the productname field) has been added to the database." I am using phpmyadmin, so should all the data that is submitted show up in there? Thanks Jarrod

Hi Been trying to run a query to get all rows from a table between two dates, but nothing seems to work. $query = "SELECT * FROM table WHERE date BETWEEN '%2014-11-17%' AND '%2014-11-18%'"; Strange thing if I try a search instead a query in phpmyadmin I don't see an operator called 'BETWEEN' on the remote host, but I do on my localhost. Does this mean it will never work on the remote host? Nevertheless it doesn't work on either and I do have records for both dates in the table. phpmyadmin: Version 4.1.14 localhost (wamp) Version 3.3.7deb7 on remote server Thanks

Hi all, I'v table called vehicles with id (int auto_increment) and plate_number (varchar 150). the plate_number have records like (a a a 1 1 1 1) (b b b 2 2 2 2), three chars and four numbers spliced by spaces. I'v php search page with url like this: http://localhost/vehicles/show.php?plate_number=f%20f%20f%205%205%205%205 search about plate_numbet = f f f 5 5 5 5 my php code: // pdo connection. // first sql test $sql = "SELECT * FROM vehicles WHERE plate_number LIKE '%".$_GET['plate_number']."%'"; // second sql test // $sql = "SELECT * FROM vehicles WHERE plate_number = '".$_GET['plate_number']."'"; $db->query($sql); if($db->rowcount() > 0){ // print all results... }else{ echo "There are no results."; } The query result is: There are no results.. But, when I copy the sql statements into phpmyadmin it is works fine. (there is a result). like this: SELECT * FROM vehicles WHERE plate_number LIKE '%f f f 5 5 5 5%'; OR SELECT * FROM vehicles WHERE plate_number = 'f f f 5 5 5 5'; Also i used string functions (htmlspecialchars, rawurldecode, ... ), still not work. any suggestion to solve this issue? Thanks to all -
