No Case Statement In Views + Sql 7
Oct 16, 2005I have a query which will be a subquery that I want to use a case statement on. (It is an outer join and I want to substitue nulls for a specific value.) I can make it work in query analyzer and can also make it work in a stored procedure, but I get a message that the case statement is not supported in views. So, I tried to make a function ,but they are not supported in SQL 7, and apparently stored procedures cannot be called inline in views, either. I can retrieve the desired recordset with exec sp_name, but I need the recordset to be used in another query and cannot figure out how to use the results from a Stored procedure as a subquery in a view. Any help is greatly appreciated.
Thanks,

Hi All,
Iam having 2 tables say Emp table and Department Table. Iam having a view which joins 2 tables.
example
select *,Department.DeptStatus, Department.DepartmentName from Employee INNER JOIN Department ON Department.deptno=Employee.DeptNO.
When I add a new column to the Employee table say EmployeeStatus then my view get corrupted.what i mean is that the last newly added column from emloyee table takes the Name as DeptStatus and shows values of the EmployeeStatus Column. We have been creating new Columns in SQL 2000 we never faced this issue but iam seeing this issue only in SQL Server 2005.
Thanks in Advance.

Views Or Select
Aug 2, 2007Hai, I'm an novice in Sql Server. I wanna know why we are going for VIEWS instead of SELECT statement in Sql Server 2005. However, both are going to perform the same task (i.e, Retreiving data) from the database.

Multiple Tables Used In Select Statement Makes My Update Statement Not Work?
Aug 29, 2006I 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

SQL Server 2008 :: Using Dynamic Management Views To Capture Executing Statement
Mar 19, 2015I have created a trigger on a table that get's too many updates so to analyze what records and what columns get updates I have coded a trigger that inserts into a table the record key and a flag on each column to let me know what is updates. Now that I am presenting the data to the developers I have been asked to provide the update / insert or delete statement
So on my trigger I have tried using dynamic management views but its returning the actual trigger code not the parent SQL Script that triggered it.
This is what I am using.

case when sder.[statement_start_offset] > 0 --the start of the active command is not at the beginning of the full command text

SMO Problem / Can't Select Non System Views Without Crash
Mar 5, 2006I've had a couple problems with SMO and I wonder if anyone else has. Specifically, when I run through stored procedures (just like your example) it is painfully slow. Maybe 5 a second. Another problem is filtering on nonsystem objects with either "SVR.SetDefaultInitFields(typeof(Microsoft.SqlServer.Management.Smo.View), "IsSystemObject"); or View.isSystemObject.
Both cases crash my app. Any ideas?
Below are two ways that both crash or hang.
SVR.SetDefaultInitFields(typeof(Microsoft.SqlServer.Management.Smo.View), "IsSystemObject");
foreach (Microsoft.SqlServer.Management.Smo.View view in viewCollection)
{}
OR
foreach (Microsoft.SqlServer.Management.Smo.View view in viewCollection)

VIEWs - Can It Know Wether A SELECT, UPDATE, Etc Is Executing On It
Apr 6, 2000VIEW behaviour depending on what operation is run on it.
VIEW syntax is CREATE VIEW xx AS SELECT ... It would be very convinient to know wether a select, update, insert or delete is the operation executed on it so the view could take action accordingly, ie
CREATE VIEW xxx AS SELECT ..
CASE UPDATE THEN do_this
CASE SELECT THEN do_that etc.
Does anyone know if this is possible?
Views Containing SELECT * Do Not Recompile When Table Is Modified
Mar 17, 2008If I have a view such as: SELECT T.* FROM T
When I add a column to table T the view is not updated to reflect that change.
Furthermore, if there are other columns after the * in the view (for example SELECT T.*, GETDATE() as "My Date" FROM T) the last columns will contain incorrect data.
Is there a work around for this? An "auto-recompile when tables are modified" kind of option?
Thanks
Nick
PS: This is the script I used for testing:
create table tt (
test1 int primary key,
test2 int)
go
insert into tt (test1, test2) values (1,2)
go
create view vw_tt as select *, getdate() as "My Date" from tt
go
select * from vw_tt
go
create view vw_tt2 as select * from tt
go
alter table tt add test3 int
go
select * from vw_tt
select * from vw_tt2
select * from tt
drop table tt
drop view vw_tt
drop view vw_tt2

Want A Stored Procedure To Dynamically Select Views Pulled From A Table.
Feb 1, 2007I am building a dashboard features that allows user to select reports from a dropdownlist. It is pulling from a table called Reports (cols: ReportID, Description, sqlView) In this Report table the report is associated to a view that queries the report.
And the user's selections are stored in table called UserReport (cols: userID, ReportID, createDt) .
I need to get a Dataset to contain datables of all reports selected. (for example a user select 3 reports, the dataset should contain 3 datables that represent the report).
I want to accomplish this by create a store procedure that queries the Reports table and then dynamically executes the views that related to the user selected reports. Can anyone give me an example on how to create the storeprocedure?

Bulk Insert Into Views That Select From Table On Remote Server
Jul 20, 2005Hi all,We have an application through which we are bulk inserting rows into aview. The definition of the view is such that it selects columns froma table on a remote server. I have added the servers usingsp_addlinkedserver on both database servers.When I call the Commit API of oledb I get the following error:Error state: 1, Severity: 19, Server: TST-PROC22, Line#: 1, msg:SqlDumpExceptionHandler: Process 66 generated fatal exception c0000005EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.I would like to know if we can bulk insert rows into a view thataccesses a table on the remote server using the "bulk insert" or bcpcommand. I tried a small test through SQL Query Analyser to use "bulkinsert" on a such a view.The test that I performed was the following:On database server 1 :create table iqbal (var1 int, var2 int)On database server 2 (remote server):create view iqbal as select var1,var2 from[DBServer1].[SomeDB].[dbo].[iqbal]set xact_abort onbulk insert iqbal from '\MachineIqbaliqbaldata.txt'The bulk insert operation failed with the following error message:[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionCheckForData(CheckforData()).Server: Msg 11, Level 16, State 1, Line 0General network error. Check your network documentation.Connection BrokenThe file iqbaldata.txt contents were :112233If the table that the view references is on the same server then weare able to bulk insert successfully.Is there a way by which I should be able to bulk insert rows into aview that selects from a table on a remote server. If not then couldanyone suggest a workaround. I would actually like to know someworkaround to get the code working using OLEDB. Due to unavoidablereasons I cannot output the records to the file and then use bcp tobulk insert the records in the remote table. I need to have some wayof doing it using OLEDB.Thanks in advanceIqbal

Are Embedded Views (Views Within Views...) Evil And If So Why?
Apr 3, 2006Fellow database developers,I would like to draw on your experience with views. I have a databasethat includes many views. Sometimes, views contains other views, andthose views in turn may contain views. In fact, I have some views inmy database that are a product of nested views of up to 6 levels deep!The reason we did this was.1. Object-oriented in nature. Makes it easy to work with them.2. Changing an underlying view (adding new fields, removing etc),automatically the higher up views inherit this new information. Thismake maintenance very easy.3. These nested views are only ever used for the reporting side of ourapplication, not for the day-to-day database use by the application.We use Crystal Reports and Crystal is smart enough (can't believe Ijust said that about Crystal) to only pull back the fields that arebeing accessed by the report. In other words, Crystal will issue aSelect field1, field2, field3 from ReportingView Where .... eventhough "ReportingView" contains a long list of fields.Problems I can see.1. Parent views generally use "Select * From childview". This meansthat we have to execute a "sp_refreshview" command against all viewswhenever child views are altered.2. Parent views return a lot of information that isn't necessarilyused.3. Makes it harder to track down exactly where the information iscoming from. You have to drill right through to the child view to seethe raw table joins etc.Does anyone have any comments on this database design? I would love tohear your opinions and tales from the trenches.Best regards,Rod.
