  • How to call an extended procedure from a function

    - by Alan Featherston Lago
    hi im having trouble trying to get the following function to work. CREATE FUNCTION test ( @nt_group VARCHAR(128) ) RETURNS @nt_usr TABLE ( [name] [nchar](128) NULL , [type] [char](8) NULL , [privilege] [char](9) NULL , [mapped login name] [nchar](128) NULL , [permission path] [nchar](128) NULL ) AS BEGIN INSERT INTO @nt_usr EXEC master.dbo.xp_logininfo 'DOMAIN\USER', @nt_group RETURN END As far as i know i should be allowed to call an extended stored procedure, im getting the following error Mes 443, Level 16, State 14 Could it be that xp_logininfo might return different result sets depending on the parameters? When i use openquery i can overcome this by setting this: SET FMTONLY OFF. Does anyone know if there's a similar workaround for my problem?

  • More FP-correct way to create an update sql query

    - by James Black
    I am working on access a database using F# and my initial attempt at creating a function to create the update query is flawed. let BuildUserUpdateQuery (oldUser:UserType) (newUser:UserType) = let buf = new System.Text.StringBuilder("UPDATE users SET "); if (oldUser.FirstName.Equals(newUser.FirstName) = false) then buf.Append("SET first_name='").Append(newUser.FirstName).Append("'" ) |> ignore if (oldUser.LastName.Equals(newUser.LastName) = false) then buf.Append("SET last_name='").Append(newUser.LastName).Append("'" ) |> ignore if (oldUser.UserName.Equals(newUser.UserName) = false) then buf.Append("SET username='").Append(newUser.UserName).Append("'" ) |> ignore buf.Append(" WHERE id=").Append(newUser.Id).ToString() This doesn't properly put a , between any update parts after the first, for example: UPDATE users SET first_name='Firstname', last_name='lastname' WHERE id=... I could put in a mutable variable to keep track when the first part of the set clause is appended, but that seems wrong. I could just create an list of tuples, where each tuple is oldtext, newtext, columnname, so that I could then loop through the list and build up the query, but it seems that I should be passing in a StringBuilder to a recursive function, returning back a boolean which is then passed as a parameter to the recursive function. Does this seem to be the best approach, or is there a better one?

  • Sql Paging/Sorting - Efficent method with dynamic sort?

    - by dmose
    I'm trying to implement this style of paging: http://www.4guysfromrolla.com/webtech/042606-1.shtml CREATE PROCEDURE [dbo].[usp_PageResults_NAI] ( @startRowIndex int, @maximumRows int ) AS DECLARE @first_id int, @startRow int -- A check can be added to make sure @startRowIndex isn't > count(1) -- from employees before doing any actual work unless it is guaranteed -- the caller won't do that -- Get the first employeeID for our page of records SET ROWCOUNT @startRowIndex SELECT @first_id = employeeID FROM employees ORDER BY employeeid -- Now, set the row count to MaximumRows and get -- all records >= @first_id SET ROWCOUNT @maximumRows SELECT e.*, d.name as DepartmentName FROM employees e INNER JOIN Departments D ON e.DepartmentID = d.DepartmentID WHERE employeeid >= @first_id ORDER BY e.EmployeeID SET ROWCOUNT 0 GO This method works great, however, is it possible to use this method and have dynamic field sorting? If we change this to SELECT e.*, d.name as DepartmentName FROM employees e INNER JOIN Departments D ON e.DepartmentID = d.DepartmentID WHERE employeeid >= @first_id ORDER BY e.FirstName DESC It breaks the sorting... Is there any way to combine this method of paging with the ability to sort on different fields?

  • How to Use .NET Assembly from Legacy SQL Server 2000 DTS

    - by shyneman
    Hi All, I have a .NET assembly that needs to be called from a DTS package. There are two options I am considering to get this to work: 1) write a COM-callable wrapper for the .NET assembly and have the VBScript create the COM object to use 2) write a .NET command-line exe that uses that .NET assembly and have the VBScript execute that exe Can anybody comment on the pros/cons of either approach and which is the better way of doing this? If there are other solutions, I'd love to hear them too. Thanks a lot for any input.

  • SQL count NULL cells

    - by Giuseppe
    Dear All, I have the following problem. I have a table in a db, with many columns. I can do different kind of select queries, to show, for example, for each record that satisfies a condition: all cells from columns with names ending in _t0 all cells from columns with names ending in _t1 ... To get the column lists to form the queries I use the information schema. Now, the problem: each query returns a record with a subset of the columns of the big table. This means that I can get a row of (all!) NULLs. How can I ask my query to reject such rows without having to type in explicitely the column names (i.e. by saying where col_1 is not null, col_2 is not null...)? Is it possible? Thanks in advance!!!

  • SQL Query - Need some basic help

    - by Chuck Folds
    I'm in need of some basic TSQL help. Here's my table layout: Orders Table SSN ZipCode ZipLookup Table ZipCode State All columns are varchars. How would I get a list of States with the number of distinct SSN's in each state? Preferably, if a particular SSN has orders from multiple states only the state with the most orders would be counted for that SSN. Thank you for any tips you can give me.

  • SQL Select * from multiple tables

    - by zaf
    Using PHP/PDO is it possible to use a wildcard for the columns when a select is done on multiple tables and the returned array keys are fully qualified to avoid column name clash? example: SELECT * from table1, table2; gives: Array keys are 'table1.id', 'table2.id', 'table1.name' etc. I tried "SELECT table1.*,table2.* ..." but the returned array keys were not fully qualified so columns with the same name clashed and were overwritten.

  • SQL joining 3 tables when 1 table is emty

    - by AdRock
    I am trying to write a query that connects 3 tables. The first table is info about each festival The second table is the number of votes for each festival The third table is reviews for each festival I want to join all 3 tables so i get all the feilds from table1, join table1 with table2 on the festivalid but i also need to count the number of records in table 3 that applys to each festival. The first 2 tables give me a result becuase they both have data in them but table 3 is empty becuase there are no reviews yet so adding that to my query fives me no results SELECT f.*, v.total, v.votes, v.festivalid, r.reviewcount as count FROM festivals f INNER JOIN vote v ON f.festivalid = v.festivalid INNER JOIN (SELECT festivalid, count(*) as reviewcount FROM reviews) GROUP BY festivalid) as r on r.festivalid = v.festivalid

  • How to combine two sql queries?

    - by plasmuska
    Hi Guys, I have a stock table and I would like to create a report that will show how often were items ordered. "stock" table: item_id | pcs | operation apples | 100 | order oranges | 50 | order apples | -100 | delivery pears | 100 | order oranges | -40 | delivery apples | 50 | order apples | 50 | delivery Basically I need to join these two queries together. A query which prints stock balances: SELECT stock.item_id, Sum(stock.pcs) AS stock_balance FROM stock GROUP BY stock.item_id; A query which prints sales statistics SELECT stock.item_id, Sum(stock.pcs) AS pcs_ordered, Count(stock.item_id) AS number_of_orders FROM stock GROUP BY stock.item_id, stock.operation HAVING stock.operation="order"; I think that some sort of JOIN would do the job but I have no idea how to glue queries together. Desired output: item_id | stock_balance | pcs_ordered | number_of_orders apples | 0 | 150 | 2 oranges | 10 | 50 | 1 pears | 100 | 100 | 1 This is just example. Maybe, I will need to add more conditions because there is more columns. Is there a universal technique of combining multiple queries together?

  • MS SQL: Mitigating schema changes/upgrades

    - by bradhe
    I haven't spent a ton of time researching this yet, mostly looking for best practices on upgrading/changing DB schemas. We're actively developing a new product and as such we often have additions or changes to our DB schema. We also have many copies of the DB -- one for the test environment, one for the prod environment, dev environments, you name it. We don't really want to have to blow away test data every time we want to make a change to the DB. s Are there good ways of automating this or handling this? None of us have really ever had to deal with this so...

  • SQL Server Full Text Search Leading Wildcard

    - by aherrick
    After taking a look at this SO question and doing my own research, it appears that you cannot have a leading wildcard while using full text search. So in the most simple example, if I have a Table with 1 column like below: TABLE1 coin coinage undercoin select COLUMN1 from TABLE1 where COLUMN1 LIKE '%coin%' Would get me the results I want. How can I get the exact same results with FULL TEXT SEARCH enabled on the column? The following two queries return the exact same data, which is not exactly what I want. SELECT COLUMN1 FROM TABLE1 WHERE CONTAINS(COLUMN1, '"coin*"') SELECT COLUMN1 FROM TABLE1 WHERE CONTAINS(COLUMN1, '"*coin*"')

  • SQL ConnectionString in web.config and global.asax implications

    - by rlb.usa
    This is going to sound very odd, but I have a web.config like this: <connectionStrings> <remove name="LocalSqlServer"/> <add name="LocalSqlServer" connectionString="Data Source=BACKUPDB;..." providerName="System.Data.SqlClient"/> </connectionStrings> And a global.asax like this: void Session_Start(object sender, EventArgs e) { // Code that runs when a new session is started if (Application["con"] == null || Application["con"] == "") { Application["con"] = "Data Source=PRODUCTIONDB;..."; } } And EVERYWHERE in my code, I reference my ConnectionStrings like this: SqlConnection con = new SqlConnection(Convert.ToString(HttpContext.Current.Application["con"])); However, I see that everything I do inside this application goes to BACKUP db instead of PRODUCTIONDB. What is going on, how could this happen, and why? It doesn't make any sense to me, and it got me into a lot of trouble. We use LocalSqlServer string for FormsAuthentication.

  • Sql query - selecting top 5 rows and further selecting rows only if User is present

    - by Gublooo
    Hello, I kind of stuck on how to implement this query - this is pretty similar to the query I posted earlier but I'm not able to crack it. I have a shopping table where everytime a user buys anything, a record is inserted. Some of the fields are * shopping_id (primary key) * store_id * user_id Now what I need is to pull only the list of those stores where he's among the top 5 visitors: When I break it down - this is what I want to accomplish: * Find all stores where this UserA has visited * For each of these stores - see who the top 5 visitors are. * Select the store only if UserA is among the top 5 visitors. The corresponding queries would be: select store_id from shopping where user_id = xxx select user_id,count(*) as 'visits' from shopping where store_id in (select store_id from shopping where user_id = xxx) group by user_id order by visits desc limit 5 Now I need to check in this resultset if UserA is present and select that store only if he's present. For example if he has visited a store 5 times - but if there are 5 or more people who have visited that store more than 5 times - then that store should not be selected. So I'm kind of lost here. Thanks for your help

  • Optimizing a Soundex Query for finding similar names

    - by xkingpin
    My application will offer a list of suggestions for English names that "sound like" a given typed name. The query will need to be optimized and return results as quick as possible. Which option would be most optimal for returning results quickly. (Or your own suggestion if you have one) A. Generate the Soundex Hash and store it in the "Names" table then do something like the following: (This saves generating the soundex hash for at least every row in my db per query right?) select name from names where NameSoundex = Soundex('Ann') B. Use the Difference function (This must generate the soundex for every name in the table?) select name from names where Difference(name, 'Ann') = 3 C. Simple comparison select name from names where Soundex(name) = Soundex('Ann') Option A seems like to me it would be the fastest to return results because it only generates the Soundex for one string then compares to an indexed column "NameSoundex" Option B should give more results than option A because the name does not have to be an exact match of the soundex, but could be slower Assuming my table could contain millions of rows, what would yield the best results?

  • SQL Server search filter and order by performance issues

    - by John Leidegren
    We have a table value function that returns a list of people you may access, and we have a relation between a search and a person called search result. What we want to do is that wan't to select all people from the search and present them. The query looks like this SELECT qm.PersonID, p.FullName FROM QueryMembership qm INNER JOIN dbo.GetPersonAccess(1) ON GetPersonAccess.PersonID = qm.PersonID INNER JOIN Person p ON p.PersonID = qm.PersonID WHERE qm.QueryID = 1234 There are only 25 rows with QueryID=1234 but there are almost 5 million rows total in the QueryMembership table. The person table has about 40K people in it. QueryID is not a PK, but it is an index. The query plan tells me 97% of the total cost is spent doing "Key Lookup" witht the seek predicate. QueryMembershipID = Scalar Operator (QueryMembership.QueryMembershipID as QM.QueryMembershipID) Why is the PK in there when it's not used in the query at all? and why is it taking so long time? The number of people total 25, with the index, this should be a table scan for all the QueryMembership rows that have QueryID=1234 and then a JOIN on the 25 people that exists in the table value function. Which btw only have to be evaluated once and completes in less than 1 second.
