Hello all,
I'd like to create a view which shows all specific column values
(null values for example)
as calculated values from another column,
if for example i have the table:
---------------
| col1 | col2 |
|------|------|
| 123 | null |
| 126 | 9 |
---------------
i would like the view to be:
---------------
| col1 | col2 |
|------|------|
| 123 | 6 | ----> 6, since it's the sum of col1 digits 1+2+3
| 126 | 9 |
---------------
I don't really know how to do that, although i'm quite sure it's possible, any help will be appreciated,
I have two tables, one a data table, the other a product table. I want to perform a join on the two tables with values distributed into columns based on the value in the month field.
I am going to create a custom view (SQL08R2 now, but in SQL2012 later this year). One unusual feature is that someone suggested to limit the update capability to one column, and only allow certain number of rows to update, for instance in dev stage, 1 row at a time, and change it to allow 5 rows at a time when in production.
Could you build a trigger on a view? What other options out here?
with cte as ( select DataID, Name, SubType, FileType, MimeType, VersionID, Version
from dtree A1, dversdata A2 where A1.dataid=A2.Docid And A1.Subtype='144' AND A2.mimetype='application/news-message-id' update cte set MimeType = 'application/x-outlook-msg', Subtype=749
what I want to do is to update two columns. Both are from different tables and I get an error..
1.update on this derived table daily (how/what should I do - with triggers/jobs against the original tables?) 2.create a view that would show: - by years the percentage of sold products - quarterly percentage of new customers / rebuyers / etc. - ... 3. Thinking of making a cube in BIDS (with dimensions / measures)
Hi all,I asked a similar question a few weeks ago but I didn't explain myself to well so I was hoping for some more input.I have created a webpage in Visual web developer that contains a gridview that points to an SQL table.All works well as far as searching the table and sorting. The SQL table itself is Droped ( deleted ) and then re-created every 1 minute from a query to a linked DB2 database so that we have a "live" table of our DB2 system but in SQL.....However,There is now a requirement to be able to ADD data to this SQL table. eg: a comments field.. from the website.My procedure for re-creating the SQL DB is now useless as any data added through the website would be lost when the table gets re-created.What is the best way for me to achieve a permanent table in SQL that gets updated from the Linked server DB2 but that I can also add comments from the front end (Website Gridview)..I'm assuming some sort of update query and a join to a seperate, permanent table that contains the comments?.Please help. Ray..
hiii, i am using asp.net 2005 and sql server 2005...i hav a page in which i have used gridview and sql data source..i have written the update command for the same..the problem is when i add the where clause in the query i get an error ,,,,here is the code

I have a view based on two tables. Now I want to update that view in such a manner that the columns of both the tables are going to update. Can you suggest me what code I should write so that I can update that view.
I created a View...the view looks at four seperate tables.
Next, I created an Instead of Update trigger on that view. It works fine...for a regular UPDATE...SET.
However, it throws an error when I try an update and self join based on that view:
Update T1 Set RateUsed = T1.RateUsed From Taxroll..Taxroll T1 Join Taxroll..Taxroll T2 on T1.Asmt = T2.Asmt and T1.Taxyear = T2.Taxyear Where T1.Asmt = '123456789012' And T1.Taxyear = 2007 And T2.RollChgNum = '' And T1.RollChgNum Like '%X' And IsNull(T1.RateUsed,'') > ''
Msg 414, Level 16, State 1, Line 2 UPDATE is not allowed because the statement updates view "Taxroll..Taxroll" which participates in a join and has an INSTEAD OF UPDATE trigger.
There are a few caveats: First, I thought the join issue was in the view itself. I re-created the view using no joins...all subqueries and still get the error. Second, I re-created the Instead of Update Trigger with no joins, and still get the error.
Hi,I have an application that's running fine on development servers (weband database-sql server 2000). I'm updating a record through a thirdparty component but I don't think the component is the problem. What'shappening is that I'm updating fields that are part of view. I'm onlyupdating fields in one table of the view and this works fine in thedevelopment environment.What happens in the production environment when I try to update(using the third party component) I get the following message:"Current recordset does not support updating. This may be a limitationof the provider or of the selected locktype."As an experiment I took the same code but removed the view, leavingonly the table I want to update as the record source. In that case theupdate worked. So it seems that something in the production databasedoesn't like me updating a view. However I can do that in the databasein the development environment.The third party component is dbnetgrid which works fine in thedevelopment environment. I can only conclude it's something about thedatabase that prevents me from updating this same table if it's in aview. I've talked to our DBA but he says there's no difference betweenthe databases. Any ideas would be appreciated.Neil

Is it possible to insert rows into a view, update rows in a view and delete rows in a view? If so, how does T-SQL handle it when a VIEW is the result of following query?
CREATE VIEW view_name AS SELECT column_name(s) FROM table_name1 INNER JOIN table_name2 ON table_name1.col = table_name2.col WHERE condition
I have a student table like this studentid, schoolID, previousschoolid, gradelevel.
I would like to load this table every day from student system.
During the year, the student could change schoolid, whenever there is a change, I would put current records schoolid to the previous schoolid column, and set the schoolid as the newschoolid from student system.
My question in my merge statement something like below
Merge into student st using (select * from InputStudent ins) on st.id=ins.studentid
When matched then update
set st.schoolid=ins.schoolid , st.previouschoolid= case when (st.schoolid<>ins.schoolid) then st.schoolid else st.previouschoolid end , st.grade_level=ins.grade_level ;
My question is since schoolid is et at the first line of set statement, will the second line still catch what is the previous schoolid?

Hi all, I have two tables (staging and Cdate) and neither objects has any constraints. staging table has ID, date, A, B, and C fields and Cdate has id,date and day fields. I need to update/insert date from Vdate into staging where staging ID=' ' and date is null Here is the code I wrote, however, it seemed the information was updated to one date only instead of time series - Cdate contains time series in column date. Anyone can help to fix it? Thank you for the help!
update s set s.date=c.date FROM cdate c join staging s on(s.id=c.id) Where s.date is null and id=2
Hello all,SQL Server 2000 documentationhttp://www.microsoft.com/technet/pr...rt10/c3761.mspxstates that if view is using "NOT NULL" columns of a base table, theninsert/update performed on a view must provide dummy values for thosecolumns, and code of the trigger should ignore them.But I cannot reproduce this restriction. Code below pasted to QueryAnalysershows that I can not supply dummy values for "NOT NULL" fields when I updateview and still have update done. What do I miss ?VT/*--setup step 1. execute only inside of this commentSET NOCOUNT ONCREATE TABLE TestTable(keyField INT IDENTITY(1,1),dataField1 INT NOT NULL,dataField2 INT DEFAULT 1 NOT NULL)*//* --setup step 2. execute only inside of this commentCREATE VIEW TestView ASSELECT * FROM TestTable*//*--setup step 3. execute only inside of this commentCREATE TRIGGER TestViewTrig_IUON dbo.TestViewINSTEAD OF UPDATEASBEGINSET NOCOUNT ONUPDATE TestTableSETDataField1 = inserted.DataField1,DataField2 = inserted.DataField2FROMTestTable ttINNER JOINinsertedON inserted.KeyField = tt.KeyFieldEND*//*--setup step 4. execute only inside of this commentINSERT INTO TestTable (DataField1,DataField2) Values (1,2)INSERT INTO TestTable (DataField1,DataField2) Values (3,4)INSERT INTO TestTable (DataField1,DataField2) Values (5,6)*/SELECT * FROM TestView-- SQL Server lets me not specify DataField2 when update DataField1 orreverse,-- which is opposed to what documentation saysUPDATE TestView SET DataField1 = DataField1 + 1 where KeyField = 2UPDATE TestView SET DataField2 = DataField2 + 1 where KeyField = 3SELECT * FROM TestView/*-- remove test environmentDROP VIEW TestViewDROP TABLE TestTable*/
hopefully, someone has already solved this problem
I have been assigned an application that maps data from access databases into a view in Sql Server 2005. A vb6 application does a select on the view. The recordset is then modified by the application, and eventually, the original tables will be updated with the new data. Some of the fields in the view are the result of calculations ( i.e. adding multiple varchar fields together to produce one complex varchar result ). Any of the fields that are calculated in the manner previously described have the adFldUnknownUpdatable bit set in the attributes of the recordset, and consequently, you get a -2147217887 error ( multiple-step operation .... ) when you try to change the value of the field in the recordset. Does anyone know how to get around this problem?
For an ASP.net project, I have had a DropDownList with a static ArrayList.The ArrayList will be defined from a View, where there is no Identity PK. I also have used cbxDropDownListName.SelectedIndex to add new data toa table, where an Indetity PK is used to reference the ArrayList. I am wondering how can I add an identity PK to my view? TIA,Jeffrey
I have a SQL table that consists of columns A, B and C. I am trying to construct a view consisting of all columns (i.e. A, B, C) and a computed column. This computed column has the following logic: If B is blank or null then NewColumn = A + ' - ' C else NewColumn = A + ' - ' + B I am just wondering how the SQL statement should look like....
Is there a way of changing the value of a column in a view? For example, I have a table with defect code and a description (other columns as well). In a view, I would like to see only the defect code and the description, but if the code is > 90, I would like to define what the description is.

I'm using SQL Server 2008 to solve the following exercise.
I have three Tables: Table CUSTOMER with columns: CustomerID,Company,ContactName,Phone Table ORDER with columns: OrderID,OrderDate,ShippedDate,ShipperID,Freight,CustomerID Table Shipper with columns:ShipperID,Company,Phone
I need to Create a view listing the shipper and the number of unshipped orders. I have been trying to use joins or possibly subqueries, but I'm not getting a correct result for a ShipperID with NO unshipped orders.My view should looks like: ShipperID, Company, Phone, UnshippedOrders
My duplicate check runs against the entire column. There might be another test field that has the same value, and that might be valid, so im trying to make sure that when i do the check, i am checking only against the serial number field and not all test fields.
