View / Underlying Column Definition Metadata
Mar 18, 2008
Have many views based on legacy tables that have different table and column names. Want to create a table that shows view table / column and underlying table column, e.g.
CREATE VIEW [dbo].[Branch]
AS
SELECT
divbra_id BranchID,
cmpny_id CompanyID,
divbra_cde BranchCode,
divbra_nme BranchName
FROM MyDatabase.dbo.divbranc
GO
is an existing view. I want to pull out the following metadata:
divbranc divbra_id Branch BranchID
divbranc cmpny_id Branch CompanyID
divbranc divbra_cde Branch BranchCode
divbranc divbra_nme Branch BranchName
Is there anyway to get this from SQL metadata without actually parsing the view SELECT statement in code?

Hi!
I have created a view and one of the columns in the view has an alias assigned to it.
I'm able to read the metadata from INFORMATION_SCHEMA.VIEW_COLUMN_USAGE and also lookup
from which table each column in the view orginated from except for the column that has an alias assigned to it.
Is there any other way to lookup a column that has an alias assigned to it?
Thanks alot!

Hello, i would like to know if it's possible to generate automatically a word document or an excel document that will contain all the metadata definition, for example containing the source columns names, their datatype, and the destination with their datatypes, so that it would easy to create a data dictionnary .
Thank you in advance.

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?

We have a partitioned view with 4 underlying tables. The view and eachof the underlying tables are in seperate databases on the same server.Inserts and deletes on the view work fine. We then add insert anddelete triggers to each of the underlying tables. The triggers modifya different set of tables in the same database as the view (differentthan the underlying table). The problem is those triggers aren't firedwhen inserting or deleteing via the view. Inserting or deleteing theunderlying table directly causes the the triggers to fire, but not whenthe tables are accessed as a result of using the view.Am I missing something? The triggers are 'for insert' and 'fordelete'. No 'instead of' or 'after' triggers.

I want to grant access on the below view for an end user so that he connect to our SQL server and retrieve data. The view looks like the below
CREATE VIEW DB1.[dbo].[View1]
AS
-- For brevity, I made it as simple statement.
SELECT *
From DB2.dbo.table2
GO
For the above view, it looks like I have to grant select and connect permission for the DB1. [dbo].[View1] as well as DB2.dbo.table2.
1. Is my understanding correct?
2. I want the user to access only DB1. [dbo].[View1] and not the underlying tables. Is there a way to grant access only on the view and execute the statement on a different security context so that the user can€™t access DB2.dbo.table2 directly?
3. When the user uses SQL Server Management Studio to connect to SQL server, he is able to connect and select DB2.dbo.table2 directly. Is there any way to restrict user from viewing and executing select statement on DB2 database from SQL Server Management Studio
Thanks in advance for your help
With regards

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.
Thanks

I'm using the following to get table/column names:
select so.name, sc.name
from sysobjects so, syscolumns sc
where so.id = sc.id
and so.type = 'U'
order by so.name, sc.colid
What is the equivalent for views?
Thanks

I want to create a view on the table "workorder" that contains a serial id "woid". Another table, "wo_comment" contains multiple comments for each "woid".
I would like to create a view view_workorder with a column "allcomments" that is basically a concatenation of all the comments within the table "comment".
Table: workorder has columns: woid, startdate (plus many others)
Table: wo_comment has columns: woid, comment, sequence
Desired View: view_workorder has columns: woid, startdate, allcomments
I tried to create a view as follows but get errors concerning the "CURSOR" statement making me wonder if I can use declarations and CURSORS within a view?
create view [workorder_view] as (
Select
w.woid,
w.startdate,
cast( DECLARE @all_comments nvarchar(4000),
@curr_comment nvarchar(256)
DECLARE wo_comment_cur CURSOR
FOR
SELECT woc.Comments
FROM WO_Comment as woc
WHERE woc.woid = w.woid
OPEN wo_comment_cur
FETCH NEXT FROM wo_comment_cur INTO
@curr_comment
WHILE (@@FETCH_STATUS = 0)
BEGIN
Set @all_comments = @all_comments + @curr_comment
FETCH NEXT FROM wo_comment_cur INTO
@curr_comment
END
CLOSE wo_comment_cur;
DEALLOCATE wo_comment_cur;
as nvarchar(80000)) as COMMENTS
from workorder AS w
Thanks for any help you can provide!

I want to create a login with some restriction like the following...
1.I will create a login and ll mapped to a particular DB with the Database Role 'db_datarerader' only,

3.If we Deny the View definition option he can't able to see the Objects which are there under the DB.
4.So My Clear Question is we want to display the Object like tables ,Sps...etc and we don't want to allow him to view the definition of those objects....

I'd like to find out whether or not people grant VIEW DEFINITION to their developers in UAT and PROD environments. My view is that a developer shouldn't be able to touch a PROD environment at all (we also include UAT as PROD), and any issue in a production environment should be investigated by a DBA and escalated to the dev if necessary.

Hi,
When I am trying to create an indexed view using group and COUNT(*), it gave me the following error:
€œMsg 10136, Level 16, State 1, Line 2
Cannot create index on view "AdventureWorks.Sales.vOrders" because it uses the aggregate COUNT. Use COUNT_BIG instead.€?
When I refered the SQL Books Online, I found the following statement: €œIf GROUP BY is present, the VIEW definition must contain COUNT_BIG(*) and must not contain HAVING€?.
Though my question is basic, I am curious to know the difference between COUNT() and COUNT_BIG(). The only difference I knew is COUNT_BIG() returns bigint. If this is the only difference, why can€™t we use COUNT() in indexed view definition and why COUNT_BIG() is allowed?
Regards,
-Aazad.

SELECT [DEFINITION]
FROM SYS.SQL_MODULES WHERE [OBJECT_ID] = OBJECT_ID(@OBJECTNAME)
I know I can use SP_HELPTEXT to get linebreaks, The reason I want to use this is I can exclude comments section from SQL_Modules, but cannot exclude the comments section from SP_HELPTEXT.

hello all,
i am trying to create a view but i keep getting the error 'View definition includes no output columns or no items in the FROM clause.'
below is the select statement that's the basis of my view. the explanation i got from the F1 help of enterprise manager was ...
View definition includes no output columns or no items in the FROM clause.
A view definition must have at least one table or table-structured object in the FROM clause, and must have at least one column in the select list. The view definition is missing one or both. Modify the view definition accordingly.
query:
select
Case_CaseId,
Logged,
CAST(DATEDIFF(minute, Logged, Waiting)/60.0 AS NUMERIC(9, 2)) AS Waiting,
CAST(DATEDIFF(minute, Logged, Investigating) /60.0 AS NUMERIC(9, 2)) AS Investigating,
CAST(DATEDIFF(minute, Logged, Rejected) /60.0 AS NUMERIC(9, 2)) AS Rejected,
CAST(DATEDIFF(minute, Logged, Resolved) /60.0 AS NUMERIC(9, 2)) AS Resolved,
CAST(DATEDIFF(minute, Logged, Solved) /60.0 AS NUMERIC(9, 2)) AS Solved,

Also Please suggest me some links where i can get info about the indexes that has to be created on these types of queries where joins are involved on these many tables.
Also throw some light on how to analyse the execution plan for further enhancements.
Thanks in advance

I am trying to do a schema compare and data compare via VS2012 and I am getting below error: The reverse engineering operation cannot continue because you do not have View Definition permission on the 'Target' database.
Whats interesting is I created a viewdefinition role and added the group(to which the user belongs) to the role. However I dont get the error if I make the group the dbowner. Is this a bug?

The developers in our shop have a need to explicitly grant view definition permissions to themselves on stored procedures they create in their development databases. They have dbo level permissions in these databases and although they can explicitly grant view definition permissions to other developers in the same database, they are unable to do so for themselves. When they attempt this, it appears that they are successful but when they check the stored procedure afterwards the permission is not there for themselves.
While this does not cause an issue in development, the intention is for these view definition permissions to be carried forward to the test and production databases where they only have datareader permissions.
When these stored procedures are scripted out by the dba to move to Test and Production the view definition permissions are not scripted out for the developer in question.
Is there a way that a developer with dbo rights in a database can explicitly grant themselves view definition permissions on a stored procedure they create as dbo?

In Oracle when i create any procedure i define parameter datatype linked to under lying table.
For ex
create procedure testprocedure
(param1 customer.name%type,
param2 customer.salary%type )
Here i have defined param1 and param2 with datatype of name and salary of customer table respectively.
This way i do not need to worry about modifying param1 and param2 datatypes when datatypes of name & salary of customer table changes in future.
How can i accomplish this in SQL server.

SQL table and column metadata
Is there a way to add or update the column or table (using the extended properties) description metadata via T-SQL (from within a stored procedure) or via a program (such as VB.NET using ADO)?
These metadata properties are available via the SSMS interface:
Columns via the Column Properties/Table Designer/Description
Tables via the Table Properties/Extended Properties/[Extended Property Name]
Thanks in advance,
Mark

"The external metadata column collection is out of synchronization with the data source columns. The column "Timestamp" needs to be added to the external metadata column collection"
Please tell me where I need to remove Timestamp from. Thanks

When I set a column to have a default definition that uses a UDF, I am receiving the "String or binary data would be truncated" error.
The UDF:
Code BlockALTER FUNCTION GetDefaultClientTier
(
@ClientAssets decimal(15,2)
)
RETURNS char(1)
AS
BEGIN
DECLARE @Result char(1)
-- Get the first result in case of overlaps.
SET @Result = CAST((SELECT TOP 1 ClientTier FROM ClientTiers WHERE @ClientAssets BETWEEN ClientAssetsFloor AND ClientAssetsCeiling) AS char(1))
RETURN @Result
END
ClientTier is defined as char(1) in the table. I simply have (isnull([dbo].[GetDefaultClientTier]([ClientAssets])),(null))) as the definition. I can't use a computed column because I the values need to be editable. When inserting with SSIS, the insert works fine but the column has a value of null for each row.
When putting a character as the default (like 'A') the insert works fine.
The cast is there only because I have tried everything I can think of to get around this.
Is there something simple I am overlooking?
(SQL2005 SP2)
Thanks!

Hi all!
My problem I've been struggling with is the following. I have a set of text files (around 70), each with different column numbers and types. I define Flat File Connection Managers for each of them where I can nicely rename, set data types and omit certain columns. I do this once and this will be the basis for the rest of the data process (would be nice programmatically too actually).
I would like to pump each of these text files into SQL Server tables using CREATE TABLE and BULK INSERT (because do it one-by-one is really a pain). The question is:
is there a way to obtain column information (Script Task) from a Connection Manager so I can run CREATE TABLE-s? I just need the names, data type for each nothing fancy...
(I bumped into interfaces like IDTSConnectionManagerFlatFileColumns90, which I cannot handle from the Script Task.)
Any help appreciated!

Hi,
I have an Excel file source. I keep getting this error when running the package:
"The external metadata column collection is out of synchronization with the data source columns. The column "x" needs to be updated in the external metadata column collection."
When I get this error with regular flat files, it's because I've changed the data type of a given column in the flat file connection manager. And I resolve it simply by double-clicking on the flat file source task, and viola - it corrects it for me.
How do I correct this with an Excel file? Help.
Thanks
