• Create a complex SQL query?

  - by mazzzzz

  Hey guys, I have a program that allows me to run queries against a large database. I have two tables that are important right now, Deposits and withdraws. Each contains a history of every user. I need to take each table, add up every deposit and withdraws (per user), then subtract the withdraws from the deposits. I then need to return every user whos result is negative (aka they withdrew more then they deposited). Is this possible in one query? Example: Deposit Table: |ID|UserName|Amount| |1 | Use1 |100.00| |2 | Use1 |50.00 | |3 | Use2 |25.00 | |4 | Use1 | 5.00 | WithDraw Table: |ID|UserName|Amount| |2 | Use2 | 5.00 | |1 | Use1 |100.00| |4 | Use1 | 5.00 | |3 | Use2 |25.00 | So then the result would output: |OverWithdrawers| | Use2 | Is this possible (I sure don't know how to do it)? Thanks for any help, Max

  I am using GridView in ASP.NET 2.0. I am want to show the details from 3 tables (SQL2005) in the GridView per my search crieteria (Name of Visitor,Passport Number,Name of Company).

  - by fireBand

  Hello, I have 2 tables Table1 with columns [BId,Name,Amount] Table2 with columns [CId,BId, ExpenseType,Expense]. BId Is the foreign key in Table2.

• SQL Query taking too long

  - by user345426

  I am trying to optimize the SQL query listed below. It is basically a search engine code that retrieves products based on the products name. It also checks products model number and whether or not it is enabled. This executes in about 1.6 seconds when I run it directly through the phpMyAdmin tool but takes about 3 seconds in total to load in conjunction with the PHP file it is placed in. I need to add a category search functionality and now that is crashing the MySQL server, HELP! SELECT DISTINCT p.products_id , p.products_image , p.products_price , s.specials_new_products_price, p.products_weight , p.products_unit_quantity , pd.products_name , pd.products_img_alt , pd.products_affiliate_url FROM products AS p LEFT JOIN vendors v ON v.vendors_id = p.vendors_id LEFT JOIN specials AS s ON s.products_id = p.products_id AND s.status = 1, categories AS c , products_description AS pd , products_to_categories AS p2c WHERE ( ( pd.products_name LIKE '%cleaning%' AND pd.products_name LIKE '%supplies%' ) OR ( p.products_model LIKE '%cleaning%' AND p.products_model LIKE '%supplies%' ) OR p.products_id = 'cleaning supplies' OR v.vendors_prefix = 'cleaning supplies' OR CONCAT( CAST(v.vendors_prefix AS CHAR), '-', CAST(p.products_id AS CHAR) ) = 'cleaning supplies' ) AND p.products_status = '1' AND c.categories_status = '1' AND p.products_id = pd.products_id AND p2c.products_id = pd.products_id AND p2c.categories_id = c.categories_id ORDER BY pd.products_name

• Caching images with different query strings (S3 signed urls)

  - by Brendan Long

  I'm trying to figure out if I can get browsers to cache images with signed urls. What I want is to generate a new signed url for every request (same image, but with an updated signature), but have the browser not re-download it every time. So, assuming the cache-related headers are set correctly, and all of the URL is the same except for the query string, is there any way to make the browser cache it? The urls would look something like: http://example.s3.amazonaws.com/magic.jpg?WSAccessKeyId=stuff&Signature=stuff&Expires=1276297463 http://example.s3.amazonaws.com/magic.jpg?WSAccessKeyId=stuff&Signature=stuff&Expires=1276297500 We plan to set the e-tags to be an md5sum, so will it at least figure out it's the same image at that point? My other option is to keep track of when last gave out a url, then start giving out new ones slightly before the old ones expire, but I'd prefer not to deal with session info.

• Multiple column Union Query without duplicates

  - by Adam Halegua

  I'm trying to write a Union Query with multiple columns from two different talbes (duh), but for some reason the second column of the second Select statement isn't showing up in the output. I don't know if that painted the picture properly but here is my code: Select empno, job From EMP Where job = 'MANAGER' Union Select empno, empstate From EMPADDRESS Where empstate = 'NY' Order By empno The output looks like: EMPNO JOB 4600 NY 5300 MANAGER 5300 NY 7566 MANAGER 7698 MANAGER 7782 MANAGER 7782 NY 7934 NY 9873 NY Instead of 5300 and 7782 appearing twice, I thought empstate would appear next to job in the output. For all other empno's I thought the values in the fields would be (null). Am I not understanding Unions correctly, or is this how they are supposed to work? Thanks for any help in advance.

• Some help needed with a SQL query

  - by Psyche

  Hello, I need some help with a MySQL query. I have two tables, one with offers and one with statuses. An offer can has one or more statuses. What I would like to do is get all the offers and their latest status. For each status there's a table field named 'added' which can be used for sorting. I know this can be easily done with two queries, but I need to make it with only one because I also have to apply some filters later in the project. Here's my setup: CREATE TABLE `test`.`offers` ( `id` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY , `client` TEXT NOT NULL , `products` TEXT NOT NULL , `contact` TEXT NOT NULL ) ENGINE = MYISAM ; CREATE TABLE `statuses` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `offer_id` int(11) NOT NULL, `options` text NOT NULL, `deadline` date NOT NULL, `added` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1

• SQL Server 2008 - Conditional Query

  - by Villager

  Hello, SQL is not one of my strong suits. I have a SQL Server 2008 database. This database has a stored procedure that takes in eight int parameters. For the sake of keeping this question focused, I will use one of these parameters for reference: @isActive int Each of these int parameters will be -1, 0, or 1. -1 means "Unknown" or "Don't Care". Basically, I need to query a table such that if the int parameter is NOT -1, I need to consider it in my WHERE clause. Because there are eight int parameters, an IF-ELSE statement does not seem like a good idea. At the same time, I do not know how else to do this? Is there an elegant way in SQL to add a WHERE conditional if a parameter does NOT equal a value? Thank you!

For example, let's suppose I have the question with the id 46, with 4 answers, and 48 users voted for the option #2, 37 users for the option #1 and 39 for the option #4. I want a query that selects that and write these things: 1 37 2 48 3 0 4 39 P.S. VERY IMPORTANT! IT MUST COUNT ONLY NRANSWERS ANSWERS, AND IT MUST ECHO THE ONES THAT WEREN'T VOTED BEFORE.

• Execute query stored in variable in a very specific way

  - by niao

  Greetings, I have a problem as follows: I have an SQL variable declared: DECLARE @myVariable nvarchar(max) a third party library set a value for this variable. To simplify, lets say that the value is as follows: SET @myVariable = 'Select ROWGUID from MySampleTable' Now, I want to execute the following query: SELECT ROWGUID FROM myTable WHERE ROWGUID in (exec sp_executesql @myVariable ) However, the above statement does not work because it returns an error telling me that I can't execute stored procedure in that way. I made a workaround and this is what I wrote: create table #temptable (ID uniqueidentifier null) if(@myVariable is not null AND @myVariable !='') insert into #temptable exec sp_executesql @myVariable SELECT ROWGUID FROM myTable WHERE ROWGUID in (select * from #temptable) DROP TABLE #temptable This works fine.However I don't think it is a good idea to use temporary table. How can I achieve the same result without necessity of creating temporary tables? I am using SQL SERVER 2005
