I have found that there is some very good information available inside of the dynamic management views related to Service Broker, however I have also found this to be problematic as by default only the dba's at my company had access to these views and it took me several days to get a login that could see them. Just a thought, but it would be nice if this data were available using a view that is more accessible.
View 3 RepliesAs im diving into my new DBA role and reading as much as I can, I am a little confused on DMV's and system tables.
I've been reading through the book "SQL Server 2005 Bible", which has been very helpful. I tend to use it in conjunction with BOL whenever I come across something I want to learn more.
Last Friday, I tinkered around with DMV's, which was really cool, but I ran into something today that confused me.
Basically, it was finding out the recovery model for all the DB's on the server. The code in the book was:
SELECT [name], recovery_model_desc
FROM sys.databases;
Which turned exactly what it says it will.
however, I am confused.
I initially thought I needed to specify something in the "[name]" section, but realized, that is not the case.
My question is, why is that?
How do I know when to use [] around something?
I found this article:
http://www.databasejournal.com/features/mssql/article.php/3587906
I have been reading it.
I guess I am just really young and raw to T-SQL to know when to use the language corectly.
Is it due to the fact that the rules or syntax is a little different when using system tables?
Hope that makes sense.
Thanks.

I 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.
select@dDate as dDate, dest.[dbid], dest.[objectid], dest.[number], dest.[encrypted],
case when sder.[statement_start_offset] > 0 --the start of the active command is not at the beginning of the full command text
thencasesder.[statement_end_offset]

Hi, I have a question about nested views. Is there a way for the view not to place any locks on the underlying tables? I tried to re-write my views and its nested views with "with (nolock)" but when I view the enterprise manager, I still see exclusive and share lock on the tables. Any help would be appreciated. Thanks.
View 3 Replies View RelatedFellow 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.

View 1 Replies View RelatedHello.
Newbie here. I've only been using SQL for about a year now and have some minor questions about sql objects that reference other objects.
We have some views which reference other views in the joins. I will call one the primary view and the one being referenced in the joins as the secondary view.
Recently we made changes to the secondary view.
After which the primary views which referenced it would not work because of this change and had to be 'refreshed' by using drop/create scripts which essentially just dropped it and recreated the exact same view. I do not recall the exact error message that was returned other than it seemed to suggest that it could no longer see the secondary view since it had been changed. Nothing in the primary view was changed in any way, just the secondary.
Some here where I work have suggested off hand that this was a recompile of the primary view because the contents of the secondary changed.
My questions are:
1. Exactly why did this happen and is there a proper name for it when it does?
2. The same problem does not seem to occur when we have stored procedures referencing views in the joins which had just been changed. Why is that?
Thanks for any help on the matter. I greatly appreciate it.
Hello,
to make a report easier I'm developing it using a view of joined views of joined views.
Is there any significant performance penalty as opposed to just having one big select?
Cheers.
Is it possible to run both Sql Server Management Studio: Express and full blown side by side?
I am developing with the full blown product but would like to test Management Studio Express on the same box.
Is this possible?
Thanks
Eric
I have recently installed the SQL Server Management Studio Express but I do not find Management Tools in order to create scheduled backups and shrinking of the databases. I was under the impression that this should be included in the Management Studio. I use the SQL 2005 Express for smaller customers who run the SQL on a desktop unit. I need a way to backup the data to a server machine for backup purposes. I have uninstalled and reinstalled to no avail.
Hi Craig/Kamal,
I got your email address from your web cast. I really enjoyed the web cast and found it to be
very informative.
Our company is planning to use SSIS (VS 2005 / SQL Server 2005). I have a quick question
regarding the product. I have looked for the information on the web, but was not able to find
relevant information.
We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets
Are generated using reporting services. On examining the excel sheet, I found out that the name
Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc.
And even the number of columns are not static. It depends upon the range of date selected by the user.
I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position
Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic
Number of columns.
Your help in this respect is highly appreciated!
Thanks,
Hi Anthony, I am glad the Web cast was helpful.
Kamal and I have both moved on to other teams in MSFT and I am a little rusty in that area, though in general dynamic numbers of columns in any format is always tricky. I am just assuming its not feasible for you to try and get the source for SSIS a little closer to home, e.g. rather than using Excel output from Reporting Services, use the same/some form of the query/data source that RS is using.
I suggest you post a question on the SSIS forum on MSDN and you should get some good answers.

SQL Server Reporting Services
Hi,
I have a need to display on screen AND email a pdf report to email addresses specified at run time, executing the report with a parameter specified by the user. I have looked into data driven subscriptions, but it seems this is based on scheduling. Unfortunately for the majority of the project I will only have access to SQL 2005 Standard Edition (Production system is Enterprise), so I cannot investigate thoroughly.
So, is this possible using data driven subscriptions? Scenario is:
1. User enters parameter used for query, as well as email addresses.
2. Report is generated and displayed on screen.
3. Report is emailed to addresses specified by user.
Any tips on how to get this working?
Thanks

Hello There,I'm trying to create a view that has calculations dependent oncalculations, where the problem resides is that each time I make acalculation I must create an intermediate view so I can reference aprevious calculation.for example lets say I have my_table that has columns a & b. now I wanta view that has a & b, c = a + b, and d = c + 1.this is grossly simplified, the calculations I actually use are fairlycomplex and copying / pasting them is out of the question.so what I have is my_view_a which makes column c, and my my_view_finalwhich makes column d (however, in my real application I have 5 of theseviews, a/b/c/d/e/)is there anyway I can consolidate all these views into one? I wasthinking of using a stored procedure with temp tables or somethingalong those lines.I just which I can use the aliases that I create for c in d in onestep.any insight would be greatly appreciated.

SQL Server 2000 SP4 to multiple SQL Server 2005 Mobile Edition on PDAs. My DB on SQL2k is published with a single dynamic row filter using host_name() on my 'parent' table and also join filters from parent to child tables. The row filter uses joins to other tables elsewhere that are not published to evaluate what data is allowed through the filter.
E.g. Published parent table that contains suppliers names, etc. while child table is suppliers' products. The filter queries host_name(s) linked to suppliers in unpublished table elsewhere.
First initial sync with snapshot is correct and as I expected - PDA receives only the data from parent (and thus child tables) that matches the row filter for the host_name provided.
However - in my scenario host_name <--> suppliers may later be updated E.g. more suppliers assigned to a PDA for use or vice versa. But when I merge the mobile DB, the new data is not downloaded? Tried re-running snapshot, etc., no change.
Question: I thought the filters would remain dynamic and be applied on each sync?
I run a 'harmless' update on parent table using TSQL e.g. "update table set 'X' = 'X'" and re-sync. Now the new parent records are downloaded - but the child records are not!
Question: I wonder why if parent records are supplied, why not child records?
If I delete existing DB and sync new, I get the updated snapshot and all is well - until more data added back at server...
Any help would be greatly appreciated. Is it possible (or not) to have dynamic filters run during second or subsequent merge?
I have tried building an Inline TVF, as I assume this is how it would be used on the DB; however, I am receiving the following error on my code, I must be missing a step somewhere, as I've never done this before. I'm lost on how to implement this clr function on my db?

I have a Stored Procedure for processing a Bill of Material.
One column on the Assembly Table is a Function Name that contains some busniess rules.
OK, now I'm doing a Proof of Concept and I'm stumped.
Huuuuh!
I will ultimately have about 100 of these things. My plan was using Dynamic SQL to go execute the function.
Note: The function just returns a bit.
So; here's what I had in mind ...
if isnull(@FnNameYN,'') <> ''
exec spinb_CheckYN @FnNameYN, @InvLineID, @FnBit = @FnBit output
CREATE PROCEDURE dbo.spinb_CheckYN
@FnNameYN varchar(50),
@InvLineID int,
@FnBit bit output
AS
declare @SQL varchar(8000)
set @SQL = '
if dbo.' + @FnNameYN + ' (' + convert(varchar(31),@InvLineID) + ')) = 1
set @FnBit = 1
else
set @FnBit = 0'
exec (@SQL)
GO
Obviously; @FnBit is not defined in @SQL so that execution will not work.
Server: Msg 137, Level 15, State 1, Line 4
Must declare the variable '@FnBit'.
Server: Msg 137, Level 15, State 1, Line 5
Must declare the variable '@FnBit'.
So; is there a way to get a value out of a Dynamic SQL piece of code and get that value INTO my OUTPUT variable?
My many thanks to anyone who can solve this riddle for me.
Thank You!
Sigh: For now, it looks like I'll have a huge string of "IF" statements for each business rule function, as follows:
Hopefully a better solution comes to light.
------ Vertical Build1 - Std Vanes -----------
if @FnNameYN = 'fnb_YN_B1_14'
BEGIN
if dbo.fnb_YN_B1_14 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END
------ Vertical Build1 - Scissor Vanes -----------
if @FnNameYN = 'fnb_YN_B1_15'
BEGIN
if dbo.fnb_YN_B1_15 (convert(varchar(31),@InvLineID) ) = 1

I have a requirment which i have partly accomplished , but could not get through completely
i have a file which comes in a standard format ending with date and seq number ,
suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on .
then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder
what i have taken apprach is
script task select source file --------------------> data flow task------------------------------------------> script task to destination file
dataflow task -------------------------> does count and copy in delimited format
what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task .
but cannot work the dynamic pick of a source file.
please advise with your comments or solution you have
I am trying to create an ssis package with dynamic csv file as output. and out format contains query output.
sample file name:
Unique identifier + query output + systemdate();
The expression is looking like this.
@[User::FilePath] + @[User::FileName] + ".CSV"
-- user filepath is a variable from ssis package. File name is the output from SQL query. using script task i have assigned the values to @[User::FileName] .
When I debugged the script task the value getting properly but same variable am using for Flafile destination. but its not working.
I have created a dynamic SQL program that returns a range of columns (1 -12) based on the date range the user may select. Each dynamic column is month based, however, the date range may overlap from one year to another. Thus, the beginning month for one selection may be October 2005, while another may have the beginning month of January 2007.
Basically, the dynamic SQL is a derived Pivot table. The problem that I need to resolve is how do I now use this dynamic result set in a Report. Please keep in mind that the name of the columns change based on the date range select.
I have come to understand that a dynamic anything is a moving target!
Please advise.

Is there a performance hit running a sp against a view versus a base table. The view just excludes
several of the records based on some criteria, and all the data I will be retreiving is included in
the view. Or should I just stick my criteria in the SP to exclude the data?
