Hello,
I want to write a t-sql script, that reads the select statement from
an existing view.
How can I get access to the select-statement in the view definition?
Help!
Thanks a lot.

Wuddup,
I am trying to create a view that encapsulates some specific info from many different tables. I have about 30 tables all with exactly the same field names and field types. I want to take 3 of the fields from every table and put them together into one 'VIEW' so I can run more efficient queries. SQL however, doesn't let you 'combine' 2 columns from different tables into one column in the view. (making sense?)
I tried running a 'UNION' but you are specifically NOT allowed to run a union in a create view statement. Anyone have any ideas?
Write a CREATE VIEW statement that defines a view named Invoice Basic that returns three columns: VendorName, InvoiceNumber, and InvoiceTotal. Then, write a SELECT statement that returns all of the columns in the view, sorted by VendorName, where the first letter of the vendor name is N, O, or P.
This is what I have so far,
CREATE VIEW InvoiceBasic AS
SELECT VendorName, InvoiceNumber, InvoiceTotal
From Vendors JOIN Invoices
ON Vendors.VendorID = Invoices.VendorID
[code]...
I compared view query plan with query plan if I run the same statementfrom view definition and get different results. View plan is moreexpensive and runs longer. View contains 4 inner joins, statisticsupdated for all tables. Any ideas?

Is there anyway to create view with read only option as in Oracle ? (OR) is there any
workaround for the same ?
Please advice,

I have a DB migrated from SQL Server 2000 to SQL Server 2005 and I
have a strange problem that I don't find any reason.
I make a simple SQL Query with one table showing all the fields and
everything goes well. But when I insert another auxiliar table and
showing one field, then I can't change any field of the main table.
SQL Server shows me the message Read Only Cell. Why this happens? This problem didn't happen in SQL Server 2000.
The select sentence that works:

I need to create a new login with SELECT rights so the users can view all tables with no UPDATE, DELETE, OR INSERT rights. But this user needs to be able to CREATE VIEWS. I have assigned the user to the Public role and gone in and modified Securables for the Database to be able to CREATE VIEW. When I connect using my new user and try to create a view, I get the error message: CREATE VIEW permissions denied in database 'test01'.
Help Please

This is my first post, so if i have not posted things in the best manner please lemme know how to be more informative,clear, so that i can learn.
So i have made a view with the following command
GO
/****** Object: View [dbo].[AppraisalView_C] Script Date: 10/11/2007 12:10:43 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER VIEW [dbo].[AppraisalView_C]
AS
SELECT a.Counter
,a.DateCreated
,a.DateModified
,a.UserCreated
,a.UserModified
,a.AppraisalDate_C
,a.TypeID_C
,a.Customer_C
,a.Employee_C
,b.Notes_C
,b.Value_C
,b.AppraisalLineItemID_C
,b.AppraisalID_C
FROM dbo.Appraisal_C AS a
INNER JOIN dbo.AppraisalLineItem_C AS b ON a.AppraisalID_C = b.AppraisalID_C
---------------------------------------------------------------------------------------
the program im working on creates the SQL call to read from this view and creates
the following query
SELECT A.[AppraisalDate_C], A.[AppraisalID_C], A.[AppraisalLineItemID_C], A.[Customer_C], A.[Employee_C], A.[Notes_C], A.[TypeID_C], A.[Value_C]
FROM AppraisalView_C A
WHERE [AppraisalView_C].[AppraisalID_C] = 'APP-000006'
but I end up getting the dreaded "Msg 4104, Level 16, State 1, Line 1 The multi-part identifier "AppraisalView_C.AppraisalID_C" could not be bound." error....
I cant change the Query that is called, but i can change the view, what is wrong?
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

View 2 Replies View RelatedHi guys,
I have the query below (running okay):

SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
FROM myTables
WHERE Conditions are true
ORDER BY Field01
The results are just as I need:
Field01 Field02

192474 22810
Because other reasons. I need to modify that query to:

SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
INTO AuxiliaryTable
FROM myTables
WHERE Conditions are true
ORDER BY Field01
SELECT DISTINCT [Field02] FROM AuxTable

Hi All!
I have a specific requirement.
I have to generate a report on the fly.
The display fields, parameters and sort conditions would be user specified at run time in a ASP.NET web form. There will be a superset of the display, filter and sort fields out of which the user cans select one or more.
From the web form, i am taking these three parts as three strings and sending them as parameters to a Stored Procedure. The Stored Procedure will read each string, and identify what are the individual fields and generates the result accordingly.
So here my requirement is that Reporting Services must read the Stored Procedure, create a dataset and even create the User Interface all at run-time as we do not know what fields are displayed at design time. The Headers for each field come from the Stored Procedure. I have to show the report based on what are the fields in the Stored procedure at that instance of time.
I hope i have explained very clearly.
I would be grateful for your contributions.
Thanks

1. Create a security group in AD
2. Add the required members to the group
3. Add the security group as a login on the SQL server (Under Security>Logins)
4. Add the security group to the specific database with Grant in Connect and Select

Hi Sql gurus :))I've got a question that I couldn't find a satisfying answer on the net.What is the difference between:1) running sql query (select from sth with nolock) with no transaction2) running sql query (select from sth) withing a TransactionScope with option Read Uncommitted dataBasically, both should do the same work. However is anyone aware of any potential problems using any of both approaches ?We use 1) to improve our web application scalability since the system works in such a way that any selects and updates on that table (sth) do not interfere with one another.However, updates are done in a TransactionScope. And when having simultaneous select with nolock and update in a Transaction scope (the select statement has a where clause and returns records that are not updated by the update statement). However sometimes ( we still cannot figure it out when) the select statement returns some records twice.For example, the select should return 1000 records , but (sometimes) it returns 1002 records ( the extra 2 records are copies of some of the original 1000 records).Removing the nolock, makes the problem does not appear - but i want to be 100% sure that nolock is our troublemaker. And if it is - why ?We also have a problem that this particular nolock select sometimes return even less records than it should.I know it sounds impossible but it happens.So anyone who has experience with select with nolock, please share :)Thanks in advance, Yani
View 4 Replies View Related"SSIS 2012 Catalog doesn't have option to give read access to SSIS Catalog to view package run reports" ... Any luck allowing power developers / operators access to READ the SQL 2012 SSIS Execution Reports without granting them SSIS_Admin or Sysadmin?

1. READ Access – We can provide a user db_datareader access. With this the user can see the objects within the SSIS catalog database, but cannot see the reports.
2. SSIS_ADMIN – Add the user to this database role in SSISDB. With this the user can view the reports. But it also provides them privileges to modify catalog information which is not expected. We can add it using below script EXEC sp_addrolemember 'ssis_admin' , 'REDMONDPAIntelAnalyst'
3. SYSADMIN - Add the user to this server role. This will make the user an admin on the SQL server. This is not intended. Is there any method available which will have provision to give read only access to see SSIS Catalog package execution reports and not having modify Catalog access.
We are trying to create a view that references lengths in both metres and feet.
What we want to do is to create a baselength column which either holds the value of the metres column or calculates the metric value of the feet column if there is no value in the metric column.
We can do all the maths for the calculations etc, it is just putting the IF statement into the view to test the values that we are struggling with.
Any help would be appreciated.

I'm trying to right a sql statement for a gridview, I want to see the last ten records added to the to the database. As you know each day someone could add one or two records, how can I write it show the last 10 records entered.
Hi,
Yesterday, we have had a sudden load in our SQL Server 2000 which resulted in several locks. There was not too much time to investigate as we had to rush. A team member had reviewed the processes in EM, Manegement, Current Activity. Looking for blocking processes and killed them.
She told me that as soon as the blocking SPID was killed, another one arose and she had to repeat the operation a dozen of time. When done, the server activity was back to normal. She noticed that more than half of the blocking processes showed that they executed the stored Proc "P_SearchProducts".
We don't own the server and the information on what had happened at that time (batches or resource intensive operations, etc.) is not available for now.
The team suggests that we set the Transaction Isolation Level to Read UNCOMMITTED for this SP. I would like to know better about locks before I go ahead.
P_SearchProducts returns 5 recordsets each one could contains from 1 to 200 rows. To achieve the results, it creates about 10 intermediate tables (SELECT ... INTO #TableX) these temp tables are then used progressively to arrive to the final results. Roughly the volume of these temp tables could be double than the final results. The developer who wrote this SP is not a guru in SQL, there is room for improvement. But here are my questions:
Q1. Could the series SELECT ... INTO #TableX in P_SearchProducts prevent or lock another connection from executing the same SP? If yes, under which conditions?
Q2. Let's assume that P_SearchProducts has a slow execution time. Could it prevent another connection from updating the Product table? And thus leading to a deadlock situation? Something like another transaction (by User2) has obtained lock on most of Product tables, except the Product table which were being slowly read by User1 executing P_SearchProducts. But User1 cannot read the other product tables b/c there are locks by User2.
Q3. If the contention issue was provoked by the slow execution time of many request to exec
P_SearchProducts (let's assume there were suddenly 50 users on the web hitting the search product feature at the same time). Could the Read Uncommitted magically resolve the contention issue, providing we accept the consequences of the dirty read.
Sorry for the long post and thank you in advance for any help.
I have a complex(long) SQL statement inside of a stored procedure which feeds several variables from 2 tables. Something like
Select @var1, @var2, etc from
table1, table2 where
table1.id = table2.id
Is there any advantage to creating a view for this statement
and selecting from that, even though this resides in a stored procedure?
Have a View where I need to enter a conditional IF_THEN_ELSE statement in a new field (field has an alias). If this were an Access query I would do following:
IIf([dbo.AR1_CustomerMaster.EmailAddress] Is Null, "A", "B")
How can I accomplish same in View design??
I am having trouble with a VIEW. I modify the view to add a sort criteria. I can Execute the SQL and get the results I am looking for. I save the VIEW. Then if I open the VIEW using the OPEN VIEW menu option(right clicking the VIEW name) the sort order I set does not work. Please help.
