• Help with simple SQL Server query

  I have to tables as follows; Employees: Name nvarchar(50), Job Title nvarchar(50) and Salary int. Employers: Name nvarchar(50), Job Title nvarchar(50) I would like to select every item from the 'Employers' table where 'Job Title' does NOT show up in the 'Employees' table. I know this is a simple query but it has me stumped. I'd be grateful for any help. Thanks.

• Trying to verify understanding of foreign keys SQL Server

  - by msarchet

  So I'm working on just a learning project to expose myself to doing some things I do not get to do at work. I'm just making a simple bug and case tracking app (I know there are a million this is just to work with some tools I don't get to). So I was designing my database and realized I've never actually used Foreign Keys before in any of my projects, I've used them before but never actually setting up a column as a FK. So I've designed my database as follows, which I think is close to correct (at least for the initial layout). However When I try to add the FK's to the linking Tables I get an error saying, "The tables present in the relationship must have the same number of columns". I'm doing this by in SQLSMS by going to the Keys 'folder' and adding a FK. Is there something that I am doing wrong here, I don't understand why the tables would have to have the same number of columns for me to add a FK relationship between the tables?

• exec problem in sql 2005

  - by IordanTanev

  Hi, i have the situation where i have two databases whith same structure. The first have some data in its datatables. I need to create a script that will transfer the data from the first database to the second. I have created this script. DECLARE @table_name nvarchar(MAX), @query nvarchar(MAX) DECLARE @table_cursor CURSOR SET @table_cursor = CURSOR FAST_FORWARD FOR Select TABLE_NAME FROM INFORMATION_SCHEMA.TABLES OPEN @table_cursor FETCH NEXT FROM @table_cursor INTO @table_name WHILE @@FETCH_STATUS = 0 BEGIN SET @query = 'INSERT INTO ' + @table_name + ' SELECT * FROM MyDataBase.dbo.' + @table_name print @query exec @query FETCH NEXT FROM @table_cursor INTO @table_name END CLOSE @table_cursor DEALLOCATE @table_cursor The problem is that when i run th script the "print @query" statement prints statement like this INSERT INTO table SELECT * FROM MyDataBase.dbo.table When i copy this and run it from Management studio it works fine. But when the script trys to run it with exec i get this error Msg 911, Level 16, State 1, Line 21 Could not locate entry in sysdatabases for database 'INSERT INTO table SELECT * FROM MPDEV090314'. No entry found with that name. Make sure that the name is entered correctly. Hope someone can tell me whot is wront with this. Best Regards, Iordan Tanev

• How to improve performance of non-scalar aggregations on denormalized tables

  - by The Lazy DBA

  Suppose we have a denormalized table with about 80 columns, and grows at the rate of ~10 million rows (about 5GB) per month. We currently have 3 1/2 years of data (~400M rows, ~200GB). We create a clustered index to best suit retrieving data from the table on the following columns that serve as our primary key... [FileDate] ASC, [Region] ASC, [KeyValue1] ASC, [KeyValue2] ASC ... because when we query the table, we always have the entire primary key. So these queries always result in clustered index seeks and are therefore very fast, and fragmentation is kept to a minimum. However, we do have a situation where we want to get the most recent FileDate for every Region, typically for reports, i.e. SELECT [Region] , MAX([FileDate]) AS [FileDate] FROM HugeTable GROUP BY [Region] The "best" solution I can come up to this is to create a non-clustered index on Region. Although it means an additional insert on the table during loads, the hit isn't minimal (we load 4 times per day, so fewer than 100,000 additional index inserts per load). Since the table is also partitioned by FileDate, results to our query come back quickly enough (200ms or so), and that result set is cached until the next load. However I'm guessing that someone with more data warehousing experience might have a solution that's more optimal, as this, for some reason, doesn't "feel right".

• SQL Joins Excluding Data

  - by Andrew

  Say I have three tables: Fruit (Table 1) ------ Apple Orange Pear Banana Produce Store A (Table 2 - 2 columns: Fruit for sale => Price) ------------------------- Apple => 1.00 Orange => 1.50 Pear => 2.00 Produce Store B (Table 3 - 2 columns: Fruit for sale => Price) ------------------------ Apple => 1.10 Pear => 2.50 Banana => 1.00 If I would like to write a query with Column 1: the set of fruit offered at Produce Store A UNION Produce Store B, Column 2: Price of the fruit at Produce Store A (or null if that fruit is not offered), Column 3: Price of the fruit at Produce Store B (or null if that fruit is not offered), how would I go about joining the tables? I am facing a similar problem (with more complex tables), and no matter what I try, if the "fruit" is not at "produce store a" but is at "produce store b", it is excluded (since I am joining produce store a first). I have even written a subquery to generate a full list of fruits, then left join Produce Store A, but it is still eliminating the fruits not offered at A. Any Ideas?

• Sql server table can be queried but not updated

  - by Nigel

  i have a table which was always updatable before, but then suddenly i can no longer update the any of the columns in the table. i can still query the whole table and the results come back very fast, but the moment i try to update a column in the table, the update query simply stalls and does nothing. i tried using select req_transactionUOW from master..syslockinfo where req_spid = -2 to see if some orphaned transaction was locking the table, but it returns no results. i can't seems to find signs of my table being locked, but simply cannot update it. any clues as to how to fix the table or whatever state it is in?

• books or online resources to prepare for .NET interviews for senior developer role

  - by RKP

  Hi, can you suggest some good books or online resources (FAQ or articles) to prepare for .NET interviews (.NET concepts, ASP.NET, C# etc) for senior developer role? something to refresh the concepts, not too much detailed. there could be stuff I haven't done before (that applies to everyone), so at least knowing little bit about it, will definitely help. google search shows me some website with lots of QA, but they are not authentic (I found some answers inaccurate). thanks in advance.

• SQL Server view: how to add missing rows using interpolation

  - by Christopher Klein

  Running into a problem. I have a table defined to hold the values of the daily treasury yield curve. It's a pretty simple table used for historical lookup of values. There are notibly some gaps in the table on year 4, 6, 8, 9, 11-19 and 21-29. The formula is pretty simple in that to calculate year 4 it's 0.5*Year3Value + 0.5*Year5Value. The problem is how can I write a VIEW that can return the missing years? I could probably do it in a stored procedure but the end result needs to be a view.

• Backing Up Transaction Logs to Tape?

  - by David Stein

  I'm about to put my database in Full Recovery Model and start taking transaction log backups. I am taking a full nightly backup to another server and later in the evening this file and many others are backed up to tape. My question is this. I will take hourly (or more if necessary) t-log backups and store them on the other server as well. However, if my full backups are passing DBCC and integrity checks, do I need to put my T-Logs on tape? If someone wants point in time recovery to yesterday at 2pm, I would need the previous full backup and the transaction logs. However, other than that case, if I know my full back ups are good, is there value in keeping the previous day's transaction log backups?

  - by JC

  Hello all, Here's a dumb question which I can't find an answer to: I have a table which contains 20 fields, a few of which are date/time. I am interested in pulling all the fields. I would like to pull the datetime fields using the to_char function but don't want to individually list out all the other fields. Is there an easy way to do this? I tried select *, tochar(dtfield) as dt2 and select tochar(dtfield) as dt2, * and both give errors. Thanks for all your help! JC

• Dynamically call a stored procedure from another stored procedure

  - by Greg

  I want to be able to pass in the name of a stored procedure as a string into another stored procedure and have it called with dynamic parameters. I'm getting an error though. Specifically I've tried: create procedure test @var1 varchar(255), @var2 varchar(255) as select 1 create procedure call_it @proc_name varchar(255) as declare @sp_str varchar(255) set @sp_str = @proc_name + ' ''a'',''b''' print @sp_str exec @sp_str exec call_it 'test' So procedure call_it should call procedure test with arguments 'a', and 'b'. When I run the above code I get: Msg 2812, Level 16, State 62, Procedure call_it, Line 6 Could not find stored procedure 'test 'a','b''. However, running test 'a','b' works fine.

• Help with complex sql query

  - by eugeneK

  To make story short, i'm building self-learning banner management system. Users will be able to insert these banners to their site when banners will be shown based on sales/impressions ratio. I have 4 tables Banners bannerID int bannerImage varchar.... SmartBanners smartBannerID int smartBannerArrayID int bannerID int impressionsCount int visibility tinyint (percents) SmartBannerArrays smartBannerArrayID int userID int Statistics bannerID int saleAmountPerDay decimal... Each night i need to generate new "visibility" for each SmartBanner based on whole SmartBannerArray that same user has. So i need to get sum of impressions and sales for each bannerID in SmartBannerArray. All comes to my mind is to use double cursor, one will loop thought SmartBannerArrays get needed values for sum of impressions and sales and then inner loop which will access each SmartBanner and change it's "visibility" percentage based on (sales/impressions)/(sumOfSales/sumOfImpressions)*100 Hope you get the picture... Is there any other way to design better tables or not to use double cursor to avoid server overload ?

• what the true nature of @ in Transct-SQL

  - by Richard77

  Hello, I reading some old ScottGu's blogs on Linq2SQL. Now I'm doing the SPROC part. I'd like to know what's the exact meaning of @variable. See this from ScottGu's Blog ALTER PROCEDURE dbo.GetCustomersDetails ( @customerID nchar(5), @companyName nvarchar(40) output ) AS SELECT @companyName = CompanyName FROM Customers WHERE CustomerID = @customerID SELECT * FROM Orders WHERE CustomerID = @customerID ORDER BY OrderID I'm kind of lost as, so far, I've though of anything preceded by a '@' as a placeholder for user input. But, in the example above, it looks like '@companyName' is used as a regular variable like in C# for instance (SELECT @companyName = ...). But, @companyName is not known yet. So, what the true nature a something preceded by a '@' like above? a vriable? a simple placeholder to accommodate user entered value? Thanks for helping

• SQL Overlapping and Multi-Column Indexes

  - by durilai

  I am attempting to tune some stored procedures and have a question on indexes. I have used the tuning advisor and they recommended two indexes, both for the same table. The issue is one index is for one column and the other is for multiple columns, of which it includes the same column from the first. My question is why and what is the difference? CREATE NONCLUSTERED INDEX [_dta_index_Table1_5_2079723603__K23_K17_K13_K12_K2_K10_K22_K14_K19_K20_K9_K11_5_6_7_15_18] ON [dbo].[Table1] ( [EfctvEndDate] ASC, [StuLangCodeKey] ASC, [StuBirCntryCodeKey] ASC, [StuBirStOrProvncCodeKey] ASC, [StuKey] ASC, [GndrCodeKey] ASC, [EfctvStartDate] ASC, [StuHspncEnctyIndctr] ASC, [StuEnctyMsngIndctr] ASC, [StuRaceMsngIndctr] ASC, [StuBirDate] ASC, [StuBirCityName] ASC ) INCLUDE ( [StuFstNameLgl], [StuLastOrSrnmLgl], [StuMdlNameLgl], [StuIneligSnorImgrntIndctr], [StuExpctdGrdtngClYear] ) WITH (SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF) ON [PRIMARY] go CREATE NONCLUSTERED INDEX [_dta_index_Table1_5_2079723603__K23] ON [dbo].[Table1] ( [EfctvEndDate] ASC )WITH (SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF) ON [PRIMARY]

• Implement functionality in PHP?

  - by Rachel

  How can we Implement Bisect Python functionality in PHP Implement function bisect_left($arr, $item); as a pure-PHP routine to do a binary-bisection search for the position at which to insert $item into $list, maintaining the sort order therein. Assumptions: Assume that $arr is already sorted by whatever comparisons would be yielded by the stock PHP < operator, and that it's indexed on ints. The function should return an int, representing the index within the array at which $item would be inserted to maintain the order of the array. The returned index should be below any elements in $arr equal to $item, i.e., the insertion index should be "to the left" of anything equal to $item. Search routine should not be linear! That is, it should honor the name, and should attempt to find it by iteratively bisecting the list and comparing only around the midpoint.

• Repeatedly execute a stored procedure

  - by manivineet

  I have a situation where I need to repeatedly execute a stored procedure Now this procedure (spMAIN) has a cursor inside which looks for a value from a table as T1,which has the following structure ID Status ---- -------- 1 New 2 New 3 success 4 Error now the cursor looks for all rows with a status of 'New' Now while processing , if that instance of the cursor encounters an error, another SP say spError needs to be called, the 'Status' column in T1 needs to be updated to 'Error' and spMAIN needs to be called again which again repeats the process, looking for rows with 'new' how do I do it? Also, also, while we are at it, what if an SP has other SPs inside it and if any of those SP raises an error, same thing needs to be done, the T1 table needs to be updated ('Error') and spMAIN needs to be called again. can you also recommend something ? here's some code ALTER PROC zzSpMain AS BEGIN DECLARE @id INT BEGIN TRY IF EXISTS ( SELECT * FROM dbo.zzTest WHERE istatus = 'new' ) BEGIN DECLARE c CURSOR FOR SELECT id FROM zztest WHERE istatus = 'new' OPEN c FETCH NEXT FROM c INTO @id WHILE @@FETCH_STATUS = 0 BEGIN PRINT @id IF @id = 2 BEGIN UPDATE zztest SET istatus = 'error' WHERE id = @id RAISERROR ( 'Error occured', 16, 1 ) END UPDATE zztest SET istatus = 'processed' WHERE id = @id FETCH NEXT FROM c INTO @id END CLOSE c DEALLOCATE c END END TRY begin CATCH EXEC zzSpError END CATCH END
