I am currently developing a stored procedure that includes a number of computed fields. Is it possible to reference a computed value, (eg. FLdA), or do I need to CREATE a temp file and then reference the FldA and FldB values. I have simplified my code, it is much more extensive in that there are numerous WHEN clauses attached to each FldA and FldB computation.
SELECT FldA = CASE
WHEN .... THEN CurQty * 1.5
WHEN .... THEN CurQty * 1.75 ELSE 0 END),
FldB = CASE .....
NewValue = CASE
WHEN .... THEN FldA * CurValue
WHEN .... THEN FldB * CurValue
etc.
I want to create a table withmember id(primary key for Students,faculty and staff [Tables])and now i want to create issues[Tables] with foreign key as member idbut in references i could not able to pass on reference as orcondition for students, faculty and staff.Thank You,Chirag
dear sirs, this is my first contribution at you reputable forum ..
I have a serious problem which is .. I want to create a trigger which runs at the begining of each month .. so I created a table which has a field --> formula --> month(getdate()) i tested it by changing the month in the windows calender and each time i change the month it is updated in the table when I crated a trigger i checked if update(sal_month) the trigger is as follows ======================================== create trigger tr_update_loan on salary_month for update as if update(sal_month) begin update hr_emp_loan set payed = payed + one_loan , rest = rest - one_loan end ========================================= it returned an error "Column 'sal_month' cannot be used in an IF UPDATE clause because it is a computed column." I tried to not to use if update() but when I change the date in the calender it is not updated in the other table
can any one help my in this because I'm doing my graduation project
Hi all, I have three textboxes in a form view 1- Qty textbox 2- price textbox 3-TotalPrice textbox which value is the result of multiplying the previous two values and then I want to Bind() the third value to the totalprice field in the database how can I do that?? (without making the database field as a computed column)
Normally, you establish referential integrity so that foreign key in one table points to a primary in another. Here is a composite key:
(A_ref, B_ref) => (A, B)
Consider a situation where A is a primary key in table T1. It is refered by T2, which has A,B as it's prmary key. An example of this situation would be a table of printers and table of batches a printer has printed at specific date. The batches are identified by Printer, Date, BatchNo within the date. Now, we create a temporary table T3, which addresses "today" batches. The "today" reference is taken from a date is taken from some record in the DB and, combined with the Printer ID and BatchNo, must point to a record in T2. Is it possible to specify such a complex relationship to ensure the referential integrity?
The advantages of the integirty are:
-- the referred records are pinned down from removal -- it is not possible to refer unexisting object; thus, the referee is ensured to refer an existing one.
I have a table with 3 computed columns, the first two reference a function for there value. The last computed column should be total of the other computed columns, however when trying to write the formula for this column SQL Server rejects it.
Am i correct in thinking it is not possible to reference other computed columns in a computed column's forumla.
My current work around is to call the functions again that the other computed columns use to generate the total, though this seems to me like a performance issue.
Hi All - I have come across the need to use a cube in AS 2005 for an application. Unfortunately this will be the first time writting an ASP.Net application which uses one. I was wondering if any of you had any good books or references that I could look at to get an idea of how I should approach this issue. Thanks in advance.
Hi, I'm doing a web application that will get some information from an ERP. At this moment I have 2 databases: 1) The aspnetdb, where I have the tables for Merbership and Role 2) The ERP database I need to put my web application tables on one of these two DB's. This tables will reference the users from the membership and some products from the ERP DB. I will store products requests that will store both UserID (from aspnetdb) and ProductID (from ERP DB). I'm thinking to put these tables on the aspnetdb, so that all web application tables stick together. But, I will loose tha ability to make joins with the ERP database, right? Do you think this will work? Can someone make some comments about this situation, and give me some tips? Thank you!
HelloSuppose a database Db1 with tables tl1 and tl2 and a second database db2with tables tl3 et tl4.Is it possible to make a join between tables of the two databases ?As for example, Select * from tl1 INNER JOIN tl3 where tl1.Field1 =tl3.Field3Thank for any helpThierry
I have a task to where I need to move a column from one table toanother. I want to be sure I update any view, stored procedure,trigger, etc. that references the column. I simply want a query thatwill report the related objects and then I will update them manuallybut before I go and try and figure out how to do this by querying thesys tables is there an sp_sproc that will do this?
I have a data list that will grow over time. The values are listed vertically in a column; most recent value at the bottom. I am trying to figure out how to setup a formula to figure out the standard deviation on the most recent 30 values automatically. For instance if the column contains 30 values and I add the 31st value, I'd like to have to have the standard deviation displayed in a cell and automatically shift from calculating on values 1-30 to values 2-31. Is this possible?
We installed SQL7 over the weekend. Everything was working peachy through yesterday. This morning SQL server is requiring all of the queries to require references to the username in the from clause...
For example
"Select * from mytable" used to work fine. Not it requires "select * from username.mytable"
I'm logged in as the same username, which is the DB Owner as well. Any idea why this is happening all the sudden?
I'm trying to create some tables in my database but I'm getting some errors... The one which is causing the most trouble is Msg 1767, Level 16, State 0, Line 38 Foreign key 'ten_fk' references invalid table 'Tenant'. I'm not sure why it's complaining... can anyone help me out here?
Cheers!

How do you add a reference if the assembly you want to reference does not live in C:WindowsMicrosoft.NETFrameworkv2.0.50727? It doesn't seem to make sense that you cannot access the connections the AquireConnection() method serves since the interfaces are defined in Microsoft.SQLServer.DTSRuntimeWrap.dll (in C:Program FilesMicrosoft SQL Server90SDKAssemblies).
For example the code below works fine, in order to make it work I had to copy DTSRuntimeWrap.dll to v2.0.50727, surely any assembly which is been added to the GAC should be available as a referece?
Public Sub Main()
Dim cmgr As Microsoft.SqlServer.Dts.Runtime.ConnectionManager = Dts.Connections("FTP Connection Manager")
Dim cn As Object = cmgr.AcquireConnection(Nothing)
Hi everyone, When you've got -for example- a derived column task linked with a Flat file and then you change any field and come back to derived column task again you have select that field with two possibilities: 1-€˜Leave as invalid column reference€™ / 2-€˜Delete invalid column reference€™
It€™s easy when just one is affected but when you have eight or ten is very tedious do the same one by one. Any way for to do same but selecting more than one?
I'm pretty new with SSIS. I have written some custom component which will read from flat file and write it into database. Between those processes, there are other processes which will analyse and transform the data being transfered. Everytime, I remove a column from upstream component, I have to go through each component to fix up column reference mapping using Invalid Column References Editor. There are lots of clicking involves just to remove a column from upstream component. My package has about 15 components. I am just wondering, is there anyway for us to prevent that editor to pop up, instead fixing invalid column reference programatically in ReInitializeMetadata?
Would anyone know of any references (online or books) that make it easier for experienced Oracle people to Learn SQL Server. The type of things I'd like to know for example are
The environment for SQL server on a PC (e.g. where the datafiles are, what's the replacement for tnslistener - general architecture info)
Any significant differences that I'd need to know for creating tables and applications, like what do I use instead of varchar2 for example.
I need to join 2 tables but the join needs to account for 2 seperate columns.
for example:
select a. type a. prod_code a. prod_type b. division
from table1 a left join table2 b on a. prod_code = b. prod_code and a. prod_type = b. prod_type
The issue is that you may have only the prod_code or prod_type and null value for the other in table1.
Ideally I want it to check for both then if 1 isn't available then it draws the division of the available. having both or one or the other determines the division it falls under.
I have a database of 900+ tables with around 3000 SPs, and views. Manually I reviewed few tables and found that tables are not referenced with FK and I applied few. There are lots of tables and SPs using them in join statement, Is there any way with which I can get each tables missing references, any DMV or other manual script which tells about this?
Does anyone know of any good references (books or web sites) that provide examples of querying AD from SQL Server? I have the database link setup and have done two very simple queries against AD but I would like to see more in-depth examples.
I know this has to be possible maybe I am just missing somthing.
I am creating a matrix report which will compare year by year quotes to orders The issue is quotes and orders each have their own dataset. I will be pivoting on JobType which is in both datasets and spelled the same. Is there a way to do this or will I have to figure out how to union the tables? If not possible why does it allow you to name the dataset in the expression?
This is my problem: I have a dynamic web reference for a SQL Server UDF coded in C#, but I am unsure of where URL for the webservice is being read from.
I am working with SQL Server 2005 to create a User Defined Function, however I need to have a web reference to the SQLReportingService2005 web service. I will be distributing this function to my customers so I need this web reference to be dynamic.
Although the webservice says it is dynamic, I do not see a app.config file to place the changing URL. Does anyone know where a dynamic web service pulls the URL from in this case?
Our company deals with financial education and typically has 9 different databases which have some cross referenced stored procedures. Every time we replicate Production database into TEST and DEV environments, we had to manually update the database references in Stored procedures. and it usually takes atleast a week and until then all the dev and test work has to wait.
Hence, I wanted to write a script, Here the code below.
-- These two variables must contain a valid database name. DECLARE @vchSearch VarChar(15), @vchReplacement VarChar(15)
SET @vchSearch = 'Search' SET @vchReplacement = 'Replacement' /* -- Select the Kaplan Database Names in the Current Server */
DECLARE @tblDBNames TABLE (vchDBName VarChar(30)) INSERT INTO @tblDBNames SELECT Name FROM MASTER.DBO.SYSDATABASES WHERE Has_DBAccess(Name)=1 And Name IN ( 'DB_DEV', 'DB_TEST', 'DB_PROD', 'WEBDB_DEV', 'WEBDB_TEST', 'WEBDB_PROD' , 'FINDB_DEV', 'FINDB_TEST', 'FINDB_PROD')
--SELECT * FROM @DBNames
IF @vchSearch NOT IN (SELECT vchDBName FROM @tblDBNames) BEGIN PRINT 'Not a Valid Search DB Name' GOTO Terminate END IF @vchReplacement NOT IN (SELECT vchDBNAME FROM @tblDBNames) BEGIN PRINT 'Not a Valid Replacement DB Name' GOTO Terminate END
-- We have Valid DB Names, lets proceed... --USE @vchReplacement
SET @vchSearch = '%' + @vchSearch + '..%' SET @vchReplacement = '%' + @vchReplacement + '..%'
-- Get Names of Stored Procedures to be altered DECLARE @tblSProcNames TABLE (vchSPName VarChar(100))
INSERT INTO @tblSProcNames SELECT DISTINCT so.Name FROM SYSOBJECTS so INNER JOIN SYSCOMMENTS sc ON sc.Id = so.Id WHERE so.XType='P' AND sc.Text LIKE @vchSearch ORDER BY so.name
-- Now, the table @tblSprocNames has the names of stored procedures to be updated. -- And we have to Some HOW ?!! grab the stored proc definition and use REPLACE() to -- update the database reference -- Then, use cursors to loop through each stored proc and upate the reference
Now, I have got stuck how to extract the body of a stored procedure into a variable.
Please Help.... I dont want spend weeks of time in the future to do this work manually.
Is there any way to enforce table references in stored procedures? For Example, we have stored procedures with a ton of different formats, "dbo.table", "table", "db.dbo.table", etc. Can we make it so that for every stored procedure, the reference must be at least "dbo.table"?
I created a new database called "TestReportServer" as mentioned in the installation instruction but I didn't see (or could select) the option "Create the report server database in SharePoint integrated mode". How can I select this option? Do I need to remove the reporing services and reinstall it again? Any suggestions?
After creating the database I get the error 'Some or all identity references could not be translated'.
The user I selected is a local administrator and has permission to all groups starting with wss.
I guess the database is not created as a sharepoint integration mode as I can start Server Management Studio and see the database. Is that a correct assumption?
I hope somebody out there can help as I am strating to bang my head towards my desk right now :-)
Is it possible to get a Computed column in one table to carry out a SELECT & SUM from a column in another table? I have tried a SELECT / FROM / WHERE construct but SQL complains about that. Regards Clive
I am working with data that has a lot of records that get updated and inserted frequently, and to avoid having to create formulas through code all over the place, I am experimenting with computed column formulas. I have a question though.. It works well for any addition or subtraction (columnA+columnB), however, when I try to use division (columnA/columnB), it only returns integers, no decimals. I would like to have decimals, particularly with a specific scale and precision and I would really like to attempt this without any coding. Any suggestions?
I have a table with fields called fname (First Name) and lname (Last Name). I need the user´s email thai is compose from lname and fname: LOWER(LEFT (fname,1) + lname)
Is there any difference between creatig this computed column ia a table or in a view in SQL Server 2000?
Maybe I am missing something very obvious, but I couldn't do it: begin trangocreate table foo (f1 int not null,f2 int not null,f3 as (f1 + f2) not null primary key clustered)gorollback trango This returns:Server: Msg 8183, Level 16, State 1, Line 8Only UNIQUE or PRIMARY KEY constraints are allowed on computed columns.
