is it possible to have a sproc with a input parm of a column name and have this column name be inserted into an exec statement that runs and provides the output as a OUTPUT parm instead of a result set?
i can get the sproc to take the column name as a parm, run the exec, but cannot figure out how to assign the "dynamic sql" output to a OUTPUT variable instead of returning the result set.
I am wondering what the advantages of using CRL Sprocs over T-SQL sprocs and what not.
Looking for such comparison and articles on websites resulted in only "how to create CRL sprocs" but none of them were talking about what they are used for in what situations.
I would really appreciate it if you guys can post comments, links and external articles.
Thank you in advance.
I find the replication put many sprocs with sp_ prefix in our database. Do you think that should be changed? I have been told not to use sp_. See http://www.sqlmag.com/Article/ArticleID/23011/sql_server_23011.html.

Due to a business rule change, I had to take what was 1 column in a table and split it off into a new table. Now I need to find every time that column is used in a SPROC and change those sprocs. Is there a way to sift through the sprocs to search for a "phrase" (the column name) -- other than reading through every one manually?
Thanks

there's a concept named cyclomatic complexity in software dev which measures the complexity of code by its number of decision points. This would be measured by # of if statements, nested if statements, etc in a method.
Do SQL queries have any type of equivalent? For example, # of joins, # of conditions, etc. Factors into a complexity metric which indicate how complex, risky or error-prone a sproc might be based on certain factors?
I've been using EM for writing stored procedures. I am ready to upgrade to something that works like an IDE. What do you use?

Hi,
Is it possible to rollback changes made to the DB when debugging a t-sql sproc in VS2005? i.e. step through the sproc, then hit rollback and be able to step through it again in the same state
Thanks, moff.
We have a growing number of servers and databases on each server that all share the same (sub)set of sprocs and UDFs. DTS packages, which we use for data import, frequently need to be copied between the servers. What is the best way to maintain this? Ideally, I would like to be able to click a button and have a script creating or altering one or more sprocs automatically run aginst all DBs on all servers. Likewise, I'd like to be able to copy DTS packages to all servers.
We use SS2000 SP4 and plan to migrate to SS2005. We also use ASP.net 2.0 and VS 2005 SP1.
Hello.
I'm using what looks to be a popular script to grant execute privileges to stored procedures, and it works great as long as the user account that you want to grant to is not a domain account.
For example, I need to grant execute to myDomaindbUsers, but get a syntax error when the script tries to execute this statement:
SET @SQL = 'GRANT EXECUTE ON [' + @Owner
+ '].[' + @StoredProcedure
+ '] TO myDomaindbUsers'
Incorrect syntax near ''.
The script works fine if a non-concatenated user account is given.
We use Active Directory to manage our access, thus the domaingroup.
Has anyone found a way around this?
Thanks in advance.
Tess
Here's the entire script for anyone who's interested:

AND name LIKE 'p%'
OPEN cursStoredProcedures
-- "Prime the pump" and get the first row
FETCH NEXT FROM cursStoredProcedures
INTO @Owner, @StoredProcedure
-- Set the return code to 0
SET @RETURN = 0
-- Encapsulate the permissions assignment within a transaction
BEGIN TRAN
-- Cycle through the rows of the cursor
-- And grant permissions
WHILE ((@@FETCH_STATUS = 0) AND (@RETURN = 0))
BEGIN
-- Create the SQL Statement. Since we€™re giving
-- access to all stored procedures, we have to
-- use a two-part naming convention to get the owner.
SET @SQL = 'GRANT EXECUTE ON [' + @Owner
+ '].[' + @StoredProcedure
+ '] TO myDomaindbUsers'
-- Execute the SQL statement
EXEC @RETURN = sp_executesql @SQL
-- Get the next row
FETCH NEXT FROM cursStoredProcedures

END
-- Clean-up after the cursor
CLOSE cursStoredProcedures
DEALLOCATE cursStoredProcedures
-- Check to see if the WHILE loop exited with an error.

BEGIN
-- Exited fine, commit the permissions
COMMIT TRAN

Hi,
Just a general question here.. I'm designing a web application that might have 50 million - 100 million rows plus. Basically its a simple logging table each row probably only 24 bytes wide, however I can see it taking quite awhile to execute.
The query is basically a group by, showing the amount of "hits" per day.
Are there any special types of strategies I should implement ? Or is a properly designed structure with indexes likely sufficient (on the right hardware of course)
Thanks for any advice!,
Mike
Are there any issues calling SQL 2005 CLR bases stored procedures and functions from a web application which uses the dotnet 1.1 framework?
I assume not, but would like advice from those who've been there...

I have been attempting to create a managed stored procedure which calls a web service using WSE 3.0 for security.
It appears that the WSE-generated config file (or possibly the app.config file) is not accessible to the .Net code.
Is there a method for using config files with CLR managed sprocs?
Thanks,
Max
In Enterprise Manager one can select several SPROCS/VIEWS using the CONTROL key and then Right-Click to script out those objects. Alternativly, pressing CONTROL-C copies, to the clipboard, the T-SQL to create the selected objects.
SQL Management Studio seems to only allow you to script one object at a time.
Is there a way in SQL Management Studio to select multiple objects and generate create or modify scripts?
There are plenty of scripts to do this on a per-DB level, but any that will allow me to generate a script for all DB's at once? Mine are split across dozens and it would be much easier to do a loop (using MS_ForeachDB ? )
View 1 Replies View RelatedWe have migrated a database (myDb2014)Â to a SQL Server 2014 instance. We have another on a 2008R2 instance (myDb2008). Both on the same server.
I have setup a linked server to the 2014 instance from the 2008R2 one.
I have a number of sprocs on myDb2008 that call TVFs and sprocs on myDb2014. This worked fine when they were both on the same instance.
Now however, I have an issue where I would have to update all the references in each calling query.
I looked into creating Synonyms but this only works for Tables/Views.
Is there a workaround to querying myDb2014 TVFs/sprocs without having to update each calling query in myDb2008?

When using a SP for getting a recordset is there any issues with using exec like in: rs.open "exec spWhatever"...
Should I use rs.open "spWhatever" or does it really matter performance wise on the SQL server?

I am trying to create a awkward sp, just need to know if i can do this somehow, here i piece of the code...
create procedure IM_SP_TrPreProc /*@TableName Varchar(255),*/ @SystemFileName Varchar(255)

I need help understanding the syntax of the "exec sql" statement.
i am looking at code that build an sql string such as
sql="exec SOMETHING Session("id")"
or something like that.
then, there is
conn.execute(sql)
My question is the "SOMETHING" in the sql statement...is what? I know it is user defined (object or variable or such), but what exactly is it? i look through the rest of the code and don;'t see SOMETHING defined elsewhere.
i am not sure if i am asking the question right. i don't understand what the SOMETHING is doing, or why it is there.
in particular, the code i am examining is
sql="exec SurveyDelete "&"'" & Session("StudentID") & " ' "
conn.execute(sql)
i understand the this statement will delete a record, but how does it handle "SurveyDelete", how does it know what the is when it is not defined anywhere else in the code?

Hi,
I have a written a SP to do indexdefrag to all user table indexes in a databases...I had to use dynamic sql so I can reuse this code for any DB...
declare @strsql varchar(500)
set @strsql = ' dbcc indexdefrag('+'''DBName'''+',554556545,3)'
exec (@strsql)
When I execute the above script, I immeaditely see the results in the query analyser like below:
Pages Scanned Pages Moved Pages Removed
------------- ----------- -------------
3 0 0
Looks like the indexdefrag did not happen since the logical fragmentation is still a high number like 30%.....
Just wondering whats goin on..
Thanks.
