  • subqueries in UPDATE SET (sql server 2005)

    - by itdebeloper
    I have a question about using subqueries in an Update statement. My example: UPDATE TRIPS SET locations = city + ', ' FROM (select Distinct city from poi where poi.trip_guid = trips.guid) Is it possible to refer to main table value (trips.guid) in subqueries? When i try to use trips.guid I get the error: "The multi-part identifier "trips.guid" could not be bound."

  • 4 table query / join. getting duplicate rows

    - by Horse
    So I have written a query that will grab an order (this is for an ecommerce type site), and from that order id it will get all order items (ecom_order_items), print options (c_print_options) and images (images). The eoi_p_id is currently a foreign key from the images table. This works fine and the query is: SELECT eoi_parentid, eoi_p_id, eoi_po_id, eoi_quantity, i_id, i_parentid, po_name, po_price FROM ecom_order_items, images, c_print_options WHERE eoi_parentid = '1' AND i_id = eoi_p_id AND po_id = eoi_po_id; The above would grab all the stuff I need for order #1 Now to complicate things I added an extra table (ecom_products), which needs to act in a similar way to the images table. The eoi_p_id can also point at a foreign key in this table too. I have added an extra field 'eoi_type' which will either have the value 'image', or 'product'. Now items in the order could be made up of a mix of items from images or ecom_products. Whatever I try it either ends up with too many records, wont actually output any with eoi_type = 'product', and just generally wont work. Any ideas on how to achieve what I am after? Can provide SQL samples if needed? SELECT eoi_id, eoi_parentid, eoi_p_id, eoi_po_id, eoi_po_id_2, eoi_quantity, eoi_type, i_id, i_parentid, po_name, po_price, po_id, ep_id FROM ecom_order_items, images, c_print_options, ecom_products WHERE eoi_parentid = '9' AND i_id = eoi_p_id AND po_id = eoi_po_id The above outputs duplicate rows and doesnt work as expected. Am I going about this the wrong way? Should I have seperate foreign key fields for the eoi_p_id depending it its an image or a product? Should I be using JOINs? Here is a mysql explain of the tables in question ecom_products +-------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------------+--------------+------+-----+---------+----------------+ | ep_id | int(8) | NO | PRI | NULL | auto_increment | | ep_title | varchar(255) | NO | | NULL | | | ep_link | text | NO | | NULL | | | ep_desc | text | NO | | NULL | | | ep_imgdrop | text | NO | | NULL | | | ep_price | decimal(6,2) | NO | | NULL | | | ep_category | varchar(255) | NO | | NULL | | | ep_hide | tinyint(1) | NO | | 0 | | | ep_featured | tinyint(1) | NO | | 0 | | +-------------+--------------+------+-----+---------+----------------+ ecom_order_items +--------------+-------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------+-------------+------+-----+---------+----------------+ | eoi_id | int(8) | NO | PRI | NULL | auto_increment | | eoi_parentid | int(8) | NO | | NULL | | | eoi_type | varchar(32) | NO | | NULL | | | eoi_p_id | int(8) | NO | | NULL | | | eoi_po_id | int(8) | NO | | NULL | | | eoi_quantity | int(4) | NO | | NULL | | +--------------+-------------+------+-----+---------+----------------+ c_print_options +------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------+--------------+------+-----+---------+----------------+ | po_id | int(8) | NO | PRI | NULL | auto_increment | | po_name | varchar(255) | NO | | NULL | | | po_price | decimal(6,2) | NO | | NULL | | +------------+--------------+------+-----+---------+----------------+ images +--------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------+--------------+------+-----+---------+----------------+ | i_id | int(8) | NO | PRI | NULL | auto_increment | | i_filename | varchar(255) | NO | | NULL | | | i_data | longtext | NO | | NULL | | | i_parentid | int(8) | NO | | NULL | | +--------------+--------------+------+-----+---------+----------------+

  • MySQL: SUM in WHERE clause

    - by checcco
    Hi guys, I've got this table CREATE TABLE `subevents` ( `id` int(11) NOT NULL AUTO_INCREMENT, `title` varchar(150) DEFAULT NULL, `content` text, `class` tinyint(4) NOT NULL DEFAULT '1', PRIMARY KEY (`id`) ) ENGINE=MyISAM Each row can have a different value in the 'class' field. I'd like to select any number of rows, ordered randomly, as long as the sum of the values in the 'class' field is equal to 100. How could I accomplish it directly in the MySQL query without doing it later in PHP? Thanks everybody!

  • postgres syntax question for OR?

    - by Dashiell0415
    The first one below works, but, just wanted to see if there's a better way... If I'm trying to find all records that start with 'C' with either a flag of 2 or a status of 9, do I need to incorporate the 'C' criteria twice? i.e., "SELECT * FROM mytable WHERE name like 'C%' AND flag = 2 OR name like 'C%' AND status = 9" Or, is there a way quicker way to write it so that I only need to set 'C%' once?

  • What is the result of this SQL query?

    - by Martin
    I'm working on a mock exam paper at the moment, however I have no set of correct answers and I'm not sure what the correct answer of this SQL query is. Given a table: foo, bar a , 1 b , 3 a , 2 c , 1 and the query: SELECT foo, sum(bar) FROM table GROUP BY foo The two ways I can see this going are either: a 3 a 3 b 3 c 1 or a 3 b 3 c 1 Thanks.

  • Can't create packages with Maven webapp

    - by cardori
    I have created a project using the following maven webapp project in eclipse: When adding a package to the project (right click project - new - package), the package gets added as a folder (I added a package named core). It does not have the usual package icon: If I try to create a new class and select a package, there are no entries in the list box. I have tried creating packages in a normal eclipse dynamic web project and these work correctly. How do I get packages in Maven enabled webapp projects?

  • is the jQuery function "change()" working in IE ?

    - by Patrick
    is the jQuery function "change()" working in IE ? I usually use it to detect changes in forms (select/unselect check boxes), and submit them automatically without having to click on submit button (which is hided). i.e. $("#views-exposed-form-Portfolio-page-1").change(function(){ $("#views-exposed-form-Portfolio-page-1").submit(); }); But in Ie it doesn't work. It seems I have to use "click" instead. thanks

    - by geosteve
    I find myself doing this a lot: script/generate migration my_new_migration .. then select & copy the generated filename, then paste it into vi to actually write the migration.

(I'm working in an SSH terminal window on linux..)
