MySQL Query - Table Set Up Issue

Aug 29, 2005

If I have a table set up like this:

Age | TINYINT | NULL (Default: NULL)

And I want the user to enter his or her name, email, and age - but AGE
is optional.

My insert would look something like:

INSERT INTO data (Name, Email, Age) VALUES ('$name', '$email', $age)

This is all good, except if the user doesn't enter an age. Then $age is
an empty variable. I thought that since the table is set up where Age
can be NULL, that this should be fine. But MySQL is giving me an error.
If $age is a number, it is no problem.

Query Time For Large MySQL Table

Nov 13, 2009

To preface my question I am a rookie in the PHP area, so forgive my incompetence. I am performing a query on a MySQL table and displaying the fields in a HTML table supported by DataTables, and due to the number of records I have stored in my table (5000+ rows) i have a big problem with the initial load time. I am using caching methods to enhance navigation beyond the initial load, however I still need a solution for reeling in the carp. I wanted to use the js datatables plugin to allow users quick access to paginated data, but if the load time hogs their memory and delays first glance...obviously I need to go a different route.

Parsed To A HTML Table (for Layout) - Customized MySQL Query?

Aug 20, 2009

We are using the x cart system from qualitive team (excuse the spelling), as their existing orders page isnt what we require at all. I have reformatted their Picking slips into an invoice like layout, this is quite a complex SQL query but here goes: There's obviously joins on each part. xcart_orders (with orderid being the primary key). The pick list then requires all customer details so there's a join on the customerid to the same column on: xcart_customers with a WHERE statement: WHERE type='P' (still with me?) There's another join, the problem is. When I have the entire SQL.


xcart_additionalfield_values (for cost prices)

The problem is, if a user orders more than 1 item, say 2 different items. I have done a standard query including all the required fields but when I run the PHP script it comes up with 2 pick lists, for the same order number if a customer has ordered more than 1 item in the same session id (at the same order). So basically 2 pick sheets appear if 2 products have been ordered, the pick sheets have the same orderid. including the 2 products (or how ever many a user orders), for including the multiple products rowed down on the same pick list? Otherwise if a user was to order 20 items we'd get 20 pick list sheets with the same orderid, not exactly the most cost effective and timed system ever.

Query A Mysql Table For Rows That Have The Same Month Value And Store As A Array For Later Use Displaying Them On A Calendar

Oct 7, 2010

the subject basically sums it up, but i am working on a calendar in php for a client that should pull events from a table and display them in the appropriate cells. the calendar table is working no prob, but what i am trying to avoid is making a separate DB call for each day of the month.

i am trying to figure out a way to store the results in an array of arrays first, then as the calendar is created, each day that has an event(s) would display some portion of the data for that even there. it's a conceptual problem i am having and i can't seem to solve it.

select day, title, desc where month = $month and year = $year order by day asc

and ultimately output something like this without hitting the DB 31 times:

title / desc
title / desc <br>
title / desc
title / desc

Editing Data In Html Table Generated From Mysql Query Which Includes Field Names

I need to be able to put data from a mysql table into a dynamic html table - that's not difficult but I need to also retrieve the column names, so for the data I can't use <?php echo $field; ?>. I can get all the data into a table using the following code:

function display_db_query($query_string, $header_bool) {
// perform the database query
$result_id = mysql_query($query_string)
or die("display_db_query:" . mysql_error());
// find out the number of columns in result
$column_count = mysql_num_fields($result_id)

But then I need to be able to edit the items in the table or to delete any of them or add another. I am not sure how to do this without any reference to the item since I won't know what the fields are.
