CLR Stored Procedures Table Permissions

Jul 4, 2013

I have an app which calls a SP, which in turn calls a CLR Stored Procedure.

The CLR stored procedure calls a number of different tables, using a Context connection string.

The issue is that the CLR SP requires the user to have permissions to the tables directly, instead of just permissions to the SP which was expected.

If I just give permission to the SP, then the CLR SP fails. So I then add the table permissions, and it then works.

So the question is, how do I raise security so the app does not have permissions on the tables?

Stored Procedures/ Table Permissions

Jul 20, 2005

Hi, is there any way that I can automate granting user permissions totables/ stored procedures in SQL server 2000?I have a whole bunch of tables and rather than having to right click eachtable/ then permissions in Enterprise manager I would like to be able toiterate through each table object in a database and grant the relevantpermissions.... Same with stored procedures.Is this possible?? If so, how can I do itThanks in advanceMark

Stored Procedures Permissions

Aug 1, 2007

Good evening:
When assigning permissions to logins/roles, etc., does a login/user with rights to a stored procedure need rights to all of the tables and views that it accesses?  
In other words: 
If you create a login/user with rights to 3 stored procs, but deny access to the same user to the tables and/or views that the SP uses, will the sproc still run?
Stupid question?  Sorry if it is.

Permissions Of CLR Stored Procedures To DB Objects

Jan 25, 2008

I need to understand the permissions that a CLR stored procedure needs when it accesses tables. In a dbo TSQL stored procedure it has owner permissions on all dbo tables, so there is no need to grant permissions on tables to the database user.

Some developers recently implemented a CLR stored procedure that returned an error with update permission denied on table name. Once I granted the user account update permission on that table, it was able to execute OK.

I have been looking for a good explanation for the way the permissions to database objects need to be setup for CLR stored procedures. For example, could I have said to modify the procedure to use the EXECUTE AS clause, instead of granting the user account direct permission on the table? Does anyone have any links to good articles on this subject?


Edit:
I have a feeling I'm on my own trying to figure out how this works. I've been searching the web for hours, and I haven't found anything that directly addresses this.

Inter-database Stored Procedures And Permissions

Jul 20, 2005

Hello all, this is my second post to this newsgroup. It's a questionabout stored procedures and permissions and how these behave betweendatabases.Here's the scenario. I have a database that stores information for asystem "A", and I have a different database on the same SQL serverthat stores the login and other info "LOGIN". I write a storedprocedure in the "A" database that checks some tables in the "LOGIN"database, let's call this "SP_A".Additionally I have a user account that accesses all appropriatestored procedures in "A" called "USER_A", and the same for the "LOGIN"database, "USER_LOGIN".Here's the part that raised my curiosity. I log into the server viaQuery Analyzer using the "USER_A" account. I run "SP_A" which does ajoin between some table in "A" and another table in "LOGIN". I give"USER_A" execute permission on "SP_A", then I try to run "SP_A" andget an error:SELECT permission denied on object '(table in "LOGIN" database)',database '(real name of "LOGIN")', owner 'dbo'Huh? how come I need to assign additional select permissions in thisdatabase if I'm not doing an actual select statement? I'm not evendynamically running a select statement through an exec function. Thisjust struck me as odd, seeing as how I never explicitly set SELECTpermission on any table in "A" for "USER_A", yet my stored procedureworks, but between databases I have to assign extra permissions for astored procedure "SP_A" access to the tables in "LOGIN".Anyone able to explain this behavior? Because I'm at a loss and I'veonly been doing this DB thing for about 2 years.Thanks in advance, all.-TJ

SSIS / MSDB Stored Procedures / Permissions

Jul 23, 2007

All,

Here is my problem, its very simple, But I dont have a solution.
To run / import / what ever I else I forgot (?) SSIS in SQL SERVER, what are permissions I'll need.

So far I have developed everything in BIDS, when I try to migrate it to a sql server by using Import package in Integration Services I got the below error.

TITLE: Import Package
------------------------------
The EXECUTE permission was denied on the object 'sp_dts_listpackages', database 'msdb', schema 'dbo'. (Microsoft SQL Native Client)

------------------------------
ADDITIONAL INFORMATION:
The EXECUTE permission was denied on the object 'sp_dts_listpackages', database 'msdb', schema 'dbo'. (Microsoft SQL Native Client)

The error is very clear in itself, While I have raised a request for the execute permission of this stored procedure, i also like to know what kind of permissions I will need in MSDB to work with out any problems. So that I dont have to go to DBA for execute permission for each error I may get for this.Right now I dont have execute permission on any of the Stored Procs in MSDB.

If any body can show any pointers that would be help full.

MS SQL Server Management Studio - Permissions And Stored Procedures

Nov 16, 2006

Hi

My website uses GET variables a lot and i'm trying to safe guard as much as possible against SQL injection attacks. I'm trying to create permissions which will deny a user to Delete/Insert/Update various tables.

I have managed this with the tables themselves, but when using a stored procedure, the tables do not take into account the user permissions which were set for that table!

Basically, how do i stop a stored procedure from Deleting/Inserting/Updating tables? :(

many thanks

Hi all,

I would like to enable users that do not belong to groups (server roles) such as sysadmin, serveradmin and don't have db permissions such as ddl_admin or db_owner to run some of the system stored procedures (such as sp_addumpdevice sp_configure sp_serveroption ...) and DBCC commands (such as DBCC CHECKFILEGROUP - requires ob_owner or sysadmin permission).

Is it possible to change permissions of SQL Server system stored procedures?

SQL Server 2012 :: Stored Procedures Compiles Even When There Is No CREATE TABLE For A Temp Table

Feb 11, 2015

i am inserting something into the temp table even without creating it before. But this does not give any compilation error. Only when I want to execute the stored procedure I get the error message that there is an invalid temp table. Should this not result in a compilation error rather during the execution time.?

--create the procedure and insert into the temp table without creating it.
--no compilation error.

SELECT GETDATE()

only on calling the proc does this give an execution error

Table Names In Stored Procedures As String Variables And Temporary Table Question

Apr 10, 2008

How do I use table names stored in variables in stored procedures?




Code Snippetif (select count(*) from @tablename) = 0 or (select count(*) from @tablename) = 1000000





I receive the error 'must declare table variable '@tablename''

I've looked into table variables and they are not what I would require to accomplish what is needed.
After browsing through the forums I believe I need to use dynamic sql particuarly involving sp_executesql. However, I am pretty new at sql and do not really understand how to use this and receive an output parameter from it(msdn kind of confuses me too). I am tryin got receive an integer count of the records from a certain table which can change to anything depending on what the user requires.




Code Snippet

if exists(Select * from sysobjects where name = @temptablename)
drop table @temptablename




It does not like the 'drop table @temptablename' part here. This probably wouldn't be an issue if I could get temporary tables to work, however when I use temporary tables i get invalid object '#temptable'.

Heres what the stored procedure does.
I duplicate a table that is going to be modified by using 'select into temptable'
I add the records required using 'Insert into temptable(Columns) Select(Columns)f rom TableA'
then I truncate the original table that is being modified and insert the temporary table into the original.

Heres the actual SQL query that produces the temporary table error.




Code Snippet
Select * into #temptableabcd from TableA

Insert into #temptableabcd(ColumnA, ColumnB,Field_01, Field_02)
SELECT ColumnA, ColumnB, Sum(ABC_01) as 'Field_01', Sum(ABC_02) as 'Field_02',
FROM TableB
where ColumnB = 003860
Group By ColumnA, ColumnB

TRUNCATE TABLE TableA

Insert into TableA(ColumnA, ColumnB,Field_01, Field_02)
Select ColumnA, ColumnB, Sum(Field_01) as 'Field_01', Sum('Field_02) as 'Field_02',
From #temptableabcd
Group by ColumnA, ColumnB




The above coding produces

Msg 208, Level 16, State 0, Line 1

Invalid object name '#temptableabcd'.

Why does this seem to work when I use an actual table? With an actual table the SQL runs smoothly, however that creates the table names as a variable problem from above. Is there certain limitation with temporary tables in stored procedures? How would I get the temporary table to work in this case if possible?

Thanks for the help.

Execute Dynamic SQL Stored Proc Without Specifying Table Level Permissions

Sep 17, 2007

I am writing a SQL 2000 stored procedure which uses an €˜EXEC @sqlString€™ statement. The @sqlString is generated at runtime. I want to give as few permissions as possible and currently allow users to access the database tables using only the stored procedures provided. However, with €˜Exec€™ I discover that I need to grant permissions on the actual tables to the users or groups. I would like to avoid this. I would also prefer not having to maintain a separate user with table level permissions and hardcoding the stored procedure with these details.
Is there anyway for me to dynamically generate the required SQL statement within my stored procedure and let SQL know that this stored procedure is allowed to select whatever tables it wants to without having to define permissions on the tables?

Using Stored Procedures To Set The Default Value Or Binding Of A Table Column

Nov 24, 2007

I want to be able to have an authorized person set or change the default values of a table column in a SQL Database. I have a stored procedure that sets the default which works fine: ALTER PROCEDURE [dbo].[addMyConst]ASBEGINALTER TABLE [dbo].[tbl1]ADD DEFAULT 70 FOR [Auto_ourlim]END(I still need to put parameters in so that I can run the stored procedure from a form, but for now....)
 To change it I know that I have to drop the constraint first like this:
ALTER PROCEDURE [dbo].[dropmyValue]ASALTER TABLE [dbo].[tbl1] DROP CONSTRAINT [Auto_ourlim] 
The problem is that when I execute the procedure I get the error that "Auto_ourlim" is not a constraint so it does not drop the Default Value. When I go over to SQL Server Management Studio Express I can see why:
If I open up the table and open up the Constraints the constraint is "DF__tbl1__Auto_ourli__5FB337D6". I could change the DROP CONSTRAINT to this, and that works, but it changes every time I add the new DEFAULT VALUE.  I don't know how to get around it. Is there a way to put wildcards around "Auto_our" in DROP CONSTRAINT [Auto_ourlim}? Any suggestions would be welcome...even if there's a totally different way to do it.
What I'm trying to ultimately accomplish is this: Column1 (AutoLimits) would be user insert to the database and then in the database it would MINUS Column2 (Auto_ourlim - set with the default value) = Column3 (Difference - a computed field in the database)

Parameter Passing - Table Name & Column Name In Stored Procedures

Mar 9, 2001

How can a Stored Procedure use a variable table name and column name ?

The statement :-

SELECT @columnname FROM @tablename

gives error "Line 5: Incorrect syntax near '@tablename'."

I am passing the parameters 'tablename' and 'columnname' into the stored procedure, (in order to select a variable column from a variable table).

If I hard-code the tablename, then I get a column of output with just the name of the column I was trying to list, e.g. surname,

i.e. SELECT @columnname FROM employeetable gives :-

surname
surname
surname
surname
surname
surname


How can I get the procedure to accept a variable table name and column name ?


I thought one way to do it would be to use the 'EXEC' statement :-

SELECT @sql = 'SELECT '+ @columnname +' FROM '+@tablename
EXEC(@sql)

but this gives error : "Incorrect syntax near the keyword 'FROM' "

although the following table works :-

SELECT @sql = 'SELECT surname FROM '+@tablename
EXEC(@sql)

The problem seems to be mainly with variable column names.

Also, we don't really want to use the EXEC statement because it will not be compiled and will be slower. (Does anyone know by how much slower ?)


Any advice would be appreciated.

Kind regards,
Ian.

Temp Table Scope In Nested Stored Procedures

Jun 8, 2001

We are migrating a SQL 6.5 application with 1900 stored procedures that use 100's of temp tables to SQL 2000.

A problem we have encountered was that we started out getting an "invalid column" errors on certain procedures. Investigation determined that the error was being generated in a nested procedure. The table that caused the error ended up being a temp table that was created using "select into". The following select statement from that temp table gave the invalid column error.

First thinking it was the "Select Into" we then discovered that the outer most procedure had created a temp table of the same name prior to executing the lower level procedure. After the select into, the next statement was a SELECT that went against what it thought was the inner temp table. However, it grabbed the outermost temp table and then couldn't find the appropriate columns and generated the error.

The solution, of course, was to rename the inner most temp table. We also remove the "select into" in the procedure by explicitly creating the temp table.

We tried creating some test procedures to attempt to reproduce this scenario without complete success.

Our test created 3 procedures (sp1 calling sp2 calling sp3) to mimic the current scenario. Sp1 created a temp table and executed sp2, which executed sp3. Sp3 created another temp table using the same name as the one created in sp1.

If we create all three procedures at the same time, it doesn't matter if we change the order in which they are created or whether we create the inner temp table explicitly or with a "select into", SQL Query Analyzer won't let us create the procedure because it finds that the temp table has been declared twice. If we create the procedures separately however, they compile and allow sp3 to create a temp table by the same name as sp1. After creating the procedures independently, they runs properly in all cases with everything in proper scope and no problems.

Admittedly, this is bad coding to start with, but what is happening with the scope of the temp tables within the stored procedures?

Thanks,
Glen Smith

Nested Queries, Stored Procedures, Temporary Table

Jul 23, 2005

Hi,I'm adapting access queries to sql server and I have difficulties withthe following pattern :query1 : SELECT * FROM Query2 WHERE A=@param1query 2: SELECT * FROM Table2 WHERE B=@param2The queries are nested, and they both use parameters.In MS Acccess the management of nested queries with parameters is soeasy (implicit declaration of parameters, transmission of parametersfrom main query to nested query)that I don't know what the syntax should be for stored procedures.The corresponding stored procedure would be something likeCREATE TABLE #TempTable (...table definition...)INSERT INTO #TempTable ExecProc spQuery2 @Param2SELECT * FROM #TempTable WHERE A=@Param1And spQuery2 would be : SELECT * FROM Table2 WHERE B=@ParamI was wondering if this syntax would work and if I can skip theexplicit declaration of #TempTable definition.Thanks for your suggestions.

Differences Between SQL Stored Procedures And Table-valued Functions

Sep 6, 2006

I am a bit confused by the difference between a stored procedure and a table-valued function. Can somebody please either give me a simple explanation, or point me at something I can read.

I thought I had it worked out, and had coded some action queries as stored procedures, and I wrote a table-valued function that was effectively an encapsulated SELECT so that SELECT * FROM Spouse(@ID) worked fine. Then I wanted to use a function SpousePair, that was similar to Spouse, to power a Gridview. I discovered that I couldn't. It seems that a SQLDataSource requires either a SELECT statement or a stored procedure. So I wrote a stored procedure SpousePair(@ID1, @ID2).

I find that whereas I tested Spouse with
SELECT * FROM SPOUSE(@ID)
I tested SpousePair with
EXEC SpousePair @ID1 @id2

Now I want to combine these: if I could I would write
SELECT * FROM SPOUSE(@ID) WHERE SPOUSEID NOT IN
(SELECT SPOUSEID FROM SpousePair(@ID1, @ID2))

However this is invalid because you can't put a stored procedure in a Select statement, and SELECT .... NOT IN (EXEC SpousePair @ID1 @ID2) is also invalid.

Is there any alternative to creating a table-valued function, SpousePairA, that is identical to SpousePair but coded as a function. I'm reluctant to do this because then I'll have two bits of quite complicated SQL logic to maintain.
