  • Refreshing metadata on user functions t-SQL

    - by luckyluke
    I am doing some T-SQL programming and I have some Views defines on my database. The data model is still changing these days and I have some table functions defined. Sometimes i deliberately use select * from MYVIEW in such a table function to return all columns. If the view changes (or table) the function crashes and I need to recompile it. I know it is in general good thing so that it prevents from hell lotta errors but still... Is there a way to write such functions so the dont' blow up in my face everytime I change something on the underlying table? Or maybe I am doing something completely wrong... Thanks for help

  • How can I iterate over a recordset within a stored procedure?

    - by David
    I need to iterate over a recordset from a stored procedure and execute another stored procedure using each fields as arguments. I can't complete this iteration in the code. I have found samples on the internets, but they all seem to deal with a counter. I'm not sure if my problem involved a counter. I need the T-SQL equivalent of a foreach Currently, my first stored procedure stores its recordset in a temp table, #mytemp. I assume I will call the secondary stored procedure like this: while (something) execute nameofstoredprocedure arg1, arg2, arg3 end

  • SQL: Order randomly when inserting objects to a table

    - by Ekaterina
    I have an UDF that selects top 6 objects from a table (with a union - code below) and inserts it into another table. (btw SQL 2005) So I paste the UDF below and what the code does is: selects objects for a specific city and add a level to those (from table Europe) union that selection with a selection from the same table for objects that are from the same country and add a level to those From the union, selection is made to get top 6 objects, order by level, so the objects from the same city will be first, and if there aren't any available, then objects from the same country will be returned from the selection. And my problem is, that I want to make a random selection to get random objects from table Europe, but because I insert the result of my selection into a table, I can't use order by newid() or rand() function because they are time-dependent, so I get the following errors: Invalid use of side-effecting or time-dependent operator in 'newid' within a function. Invalid use of side-effecting or time-dependent operator in 'rand' within a function. UDF: ALTER FUNCTION [dbo].[Objects] (@id uniqueidentifier) RETURNS @objects TABLE ( ObjectId uniqueidentifier NOT NULL, InternalId uniqueidentifier NOT NULL ) AS BEGIN declare @city varchar(50) declare @country int select @city = city, @country = country from Europe where internalId = @id insert @objects select @id, internalId from ( select distinct top 6 [level], internalId from ( select top 6 1 as [level], internalId from Europe N4 where N4.city = @city and N4.internalId != @id union select top 6 2 as [level], internalId from Europe N5 where N5.countryId = @country and N5.internalId != @id ) as selection_1 order by [level] ) as selection_2 return END If you have fresh ideas, please share them with me. (Just please, don't suggest to order by newid() or to add a column rand() with seed DateTime (by ms or sthg), because that won't work.)

  • How do I get a scalar value from a stored proc using Nettiers

    - by Micah
    I have a really simple stored procedure that looks like this: CREATE PROCEDURE _Visitor_GetVisitorIDByVisitorGUID ( @VisitorGUID AS UNIQUEIDENTIFIER ) AS DECLARE @VisitorID AS bigint SELECT @VisitorID = VisitorID FROM dbo.Visitor WHERE VisitorGUID = @VisitorGUID --Here's what I've tried RETURN @VisitorID 'Returns an IDataReader SELECT @VisitorID 'Returns an IDataReader --I've also set it up with a single output --parameter, but that means I need to pass --the long in by ref and that's hideous to me I'm trying to get nettiers to generate a method with this signature: public long VisitorService.GetVisitorIDByVisitorGUID(GUID visitorGUID); Basically I want Nettiers to call ExecuteScalar instead of ExecuteReader. What am I doing wrong?

  • Left Join Returning Extra Rows T-SQL?

    - by davemackey
    I have the following query: select * from ACADEMIC a left join RESIDENCY r on a.PEOPLE_CODE_ID = r.PEOPLE_CODE_ID where a.ACADEMIC_TERM='Fall' and r.ACADEMIC_TERM='Fall' and a.ACADEMIC_SESSION='' and a.ACADEMIC_YEAR = (Select Year(GetDate())) and r.ACADEMIC_YEAR = (Select Year(GetDate())) and (CLASS_LEVEL LIKE 'FR%' OR a.CLASS_LEVEL LIKE 'SO' OR a.CLASS_LEVEL LIKE 'JR' OR a.CLASS_LEVEL LIKE 'SR%') and r.RESIDENT_COMMUTER='R' For each person in the database it returns two rows with identical information. Yet, when I do the same query without the left join: select * from ACADEMIC a where a.ACADEMIC_TERM='Fall' and a.ACADEMIC_SESSION='' and a.ACADEMIC_YEAR = (Select Year(GetDate())) and (CLASS_LEVEL LIKE 'FR%' OR a.CLASS_LEVEL LIKE 'SO' OR a.CLASS_LEVEL LIKE 'JR' OR a.CLASS_LEVEL LIKE 'SR%') ORDER BY PEOPLE_ID It returns only one row for each person. I'm doing a left join - why is it adding an extra row? Shouldn't it only do that if I add a right join?

  • What is your most irritating quirk of t-sql

    - by Jude Wood
    I realise this is a bit flippant but it may highlight some 'interesting' features of t-sql. Or just provide some light distraction on a Friday morning... I'm currently torn between t-sql allows three part naming when dropping tables but not when dropping procudures and When using Coalesce to produce a delimited string the presence of a leading delimiter is dependant on whether the delimited string was initialised prior to calling Coalesce I'd be interested to hear yours......

  • Find records IN BETWEEN Date Range

    - by Muhammad Kashif Nadeem
    Please see attached image I have a table which have FromDate and ToDate. FromDate is start of some event and ToDate is end of taht event. I need to find a record if search criteria is in between range of dates. e.g. If a record has FromDate 2010/15/5 and ToDate 2010/15/25 and my criteria is FromDate 2010/5/18 and ToDate is 2010/5/21 then this record should be in search results becasue this is in the range of 15 to 25. Following is my search query (chunk of) SELECT m.EventId FROM MajorEvents WHERE ( (m.LocationID = @locationID OR @locationID IS NULL) OR M.LocationID IS NULL) AND ( CONVERT(VARCHAR(10),M.EventDateFrom,23) BETWEEN CONVERT(VARCHAR(10),@DateTimeFrom,23) AND CONVERT(VARCHAR(10),@DateTimeTo,23) OR CONVERT(VARCHAR(10),M.EventDateTo,23) BETWEEN CONVERT(VARCHAR(10),@DateTimeFrom,23) AND CONVERT(VARCHAR(10),@DateTimeTo,23) ) If Search Criteria is equal to FromDate or ToDate then results are ok e.g. If search criterai is DateFrom = 2010/5/15 AND DateTo = 2010/5/18 then this record will return becasue Date From is exactly what is DateFrom in db. OR If search criterai is DateFrom = 2010/5/22 AND DateTo = 2010/5/25 then this record will return becasue Date To is exactly what is DateTo in db But if anything in between this range it does not work Thanks for the help.

  • SQL syntax problem (multiple selects)

    - by user279521
    I am having problems retrieving accurate data values with my stored proc query below: CREATE PROCEDURE usp_InvoiceErrorLog @RecID int AS DECLARE @ErrorString as varchar(1000), @ErrorCode as int; Select @ErrorCode = ErrorCode from tbl_AcctRecv_WebRpt Where RecID = @RecID; IF NOT(@ErrorCode = NULL) Begin Select @ErrorString = ErrorDesc from tbl_ErrDesc Where ErrorCode = @ErrorCode End Select RecID, VendorNum, VendorName, InvNum, InvTotal, (SELECT CONVERT(VARCHAR(11), InvDate, 106) AS [DD MON YYYY]) As InvDate, TicketRequestor, ErrorCode, @ErrorString as ErrorDesc from tbl_AcctRecv_WebRpt Where RecID = @RecID The ErrorDesc column (in the final select statement at the bottom) returns a NULL value, when it should return a valid string data. Any ideas?

  • SQL SERVER - Understanding how MIN(text) works.

    - by tmercer
    I'm doing a little digging and looking for a explanation on how SQL server evaluates MIN(Varchar). I found this remark in BOL: MIN finds the lowest value in the collating sequence defined in the underlying database So if I have a table that has one row with the following values: Data AA AB AC Doing a SELECT MIN(DATA) would return back AA. I just want to understand the why behind this and understand the BOL a little better. Thanks!

  • Merge overlapping date intervals

    - by leoinfo
    Is there a better way of merging overlapping date intervals? The solution I came up with is so simple that now I wonder if someone else has a better idea of how this could be done. /***** DATA EXAMPLE *****/ DECLARE @T TABLE (d1 DATETIME, d2 DATETIME) INSERT INTO @T (d1, d2) SELECT '2010-01-01','2010-03-31' UNION SELECT '2010-04-01','2010-05-31' UNION SELECT '2010-06-15','2010-06-25' UNION SELECT '2010-06-26','2010-07-10' UNION SELECT '2010-08-01','2010-08-05' UNION SELECT '2010-08-01','2010-08-09' UNION SELECT '2010-08-02','2010-08-07' UNION SELECT '2010-08-08','2010-08-08' UNION SELECT '2010-08-09','2010-08-12' UNION SELECT '2010-07-04','2010-08-16' UNION SELECT '2010-11-01','2010-12-31' UNION SELECT '2010-03-01','2010-06-13' /***** INTERVAL ANALYSIS *****/ WHILE (1=1) BEGIN UPDATE t1 SET t1.d2 = t2.d2 FROM @T AS t1 INNER JOIN @T AS t2 ON DATEADD(day, 1, t1.d2) BETWEEN t2.d1 AND t2.d2 -- AND t1.d2 <= t2.d2 /***** this condition is useless *****/ IF @@ROWCOUNT = 0 BREAK END /***** RESULT *****/ SELECT StartDate = MIN(d1) , EndDate = d2 FROM @T GROUP BY d2 ORDER BY StartDate, EndDate /***** OUTPUT *****/ /***** StartDate EndDate 2010-01-01 2010-06-13 2010-06-15 2010-08-16 2010-11-01 2010-12-31 *****/ EDIT: I realized that the t1.d2 <= t2.d2 condition is not really useful.

  • Specifying schema for temporary tables

    - by Tom Hunter
    I'm used to seeing temporary tables created with just the hash/number symbol, like this: CREATE TABLE #Test ( [Id] INT ) However, I've recently come across stored procedure code that specifies the schema name when creating temporary tables, for example: CREATE TABLE [dbo].[#Test] ( [Id] INT ) Is there any reason why you would want to do this? If you're only specifying the user's default schema, does it make any difference? Does this refer to the [dbo] schema in the local database or the tempdb database?

  • @@TRANCOUNT and a current connection

    - by AspOnMyNet
    Assume I connect to SQL server 2008 via SQL Server Management Studio ( SSMS ) and open new window W1 by clicking on New Query tab and write the following inside W1: BEGIN TRANSACTION; If I execute this statement 5 times, and then write (inside W1) SELECT @@TRANCOUNT; , then the value returned will be 5. But if I open another window W2 ( inside the same SSMS instance and thus on the same connection ) and write inside W2 SELECT @@TRANCOUNT; then value returned will be 0. @@TRANCOUNT variable returns the number of active transactions for the current connection. Both W1 and W2 windows were opened on the same connection, so shouldn’t ( according to the above quote ) in both W1 and W2 variable @@TRANCOUNT hold the same value? thanx

  • update columns when value is numeric in tsql

    - by knittl
    i want to normalize date fields from an old badly designed db dump. i now need to update every row, where the datefield only contains the year. update table set date = '01.01.' + date where date like '____' and isnumeric(date) = 1 and date >= 1950 but this will not work, because sql does not do short circuit evaluation of boolean expressions. thus i get an error "error converting nvarchar '01.07.1989' to int" is there a way to work around this? the column also contains strings with a length of 4, which are not numbers (????, 5/96, 70/8, etc.) the table only has 60000 rows

  • SQL Server getdate() to a string like "2009-12-20"

    - by Adam Kane
    In Microsoft SQL Server 2005 and .NET 2.0, I want to convert the current date to a string of this format: "YYYY-MM-DD". For example, December 12th 2009 would become "2009-12-20". How do I do this in SQL. The context of this SQL statement in the table definiton. In other words, this is the default value. So when a new record is created the default value of the current date is stored as a string in the above format. I'm trying: SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD] But SQL server keeps converting that to: ('SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD]') so the result is just: 'SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD]' Here's a screen shot of what the Visual Studio server explorer, table, table definition, properties shows: These wrapper bits are being adding automatically and converting it all to literal string: (N' ') Here's the reason I'm trying to use something other than the basic DATETIME I was using previously: This is the error I get when hooking everything to an ASP.NET GridView and try to do an update via the grid view: Server Error in '/' Application. The version of SQL Server in use does not support datatype 'date'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentException: The version of SQL Server in use does not support datatype 'date'. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace: [ArgumentException: The version of SQL Server in use does not support datatype 'date'.] Note: I've added a related question to try to get around the SQL Server in use does not support datatype 'date' error so that I can use a DATETIME as recommended.

  • NHibernate 'IdentifierGenerationException' on an Update trigger

    - by Jan Jongboom
    In my database I have an id column defined as [autonumber] [int] IDENTITY(1,1) NOT NULL which is mapped in my .hbm.xml like: <id name="Id" column="autonumber" type="int"> <generator class="identity" /> </id> When calling session.Save() updates are successful committed to the database. When adding a versioning trigger I however get the error this id generator generates Int64, Int32, Int16 of type IdentifierGenerationException. The trigger is defined as: ALTER TRIGGER [dbo].[CatchUpdates_NVM_FDK_Kenmerken] ON [dbo].[NVM_FDK_Kenmerken] INSTEAD OF UPDATE AS BEGIN SET NOCOUNT ON UPDATE NVM_FDK_Kenmerken SET idIsActive = 0 WHERE internalId IN (SELECT internalId FROM INSERTED) INSERT INTO dbo.NVM_FDK_Kenmerken ( vestigingNummer , internalId , someOtherColumns, dateInserted, idIsActive ) SELECT vestigingNummer, internalId, someOtherColumns, GETDATE(), 1 FROM INSERTED END What am I doing wrong here? When doing manual updates everything works just fine and as expected.

  • How to get the right order for creation of stored procedure, user-defined functions and triggers

    - by PeeWee2201
    I read that object dependencies have been improved in SQL server 2008. I have a rather complex database schema containing stored procedure, user-defined functions, triggers. Can anybody give me a query that would return the right order of creation of those items based on their dependencies ? I read here that there are tools that can do the job, but I am looking for something scriptable. Also, they often give the dependencies of one object and I would like a database-wide solution. Thank you.
