BOL says (or has had added ) on the subject of IDENT_CURRENT
Exceptions
Returns NULL on error or if a caller does not have permission to view the object.
In SQL Server 2005, a user can only view the metadata of securables that the user owns or on which the user has been granted permission. This means that metadata-emitting, built-in functions such as IDENT_CURRENT may return NULL if the user does not have any permission on the object.
However am finding that SCOPE_IDENTITY does continue to function for a user who has not been granted meta data permisisons or directly (select) on the underlying table.
can somebody explain why they are different behaviours. I need to be able to capture the ID of a row just inserted (under the insert rights of my application role) I'm glad SCOPE_IDENTITY works but am nervous am working in an area of undefined behaviour ! after all its also a metadata-emitting, built-in function
My application role is the owner of the schema and the storedprocedure which trys to use IDENT_CURRENT but it consistently returns me a null when logged in as a user without admin priveleges
Hello, I have tried developped a stored proc that is using the ident_current('tablename') function to get the last Identity ID.
It was working fine. I drop and recreate the table (which reset the ID) and found that the ident_current said that the last Identity Id used was 1. The problem was that the table was empty. I insert a record and try it again. It said again that the last Identity ID was 1. After the insertion if the first record, everything is fine...
I would like to know if you know a way get 0 when the table is empty and 1 when there is only one identity id that have been used.
Thank

You can test the functionnality with the following code:
create table identCurrentBugExeample(IDnumber int IDENTITY(1,1), aChar char(1)) Declare @count as int set @count = (select count(IDnumber) from identCurrentBugExeample)
--Print the number of record in the table print @count
--Supposed to print 0 because there isn't any identity values that has been used print ident_current('identCurrentBugExeample') insert identCurrentBugExeample(aChar) values('a')
--Print 1 because the last identity used is 1 print ident_current('identCurrentBugExeample') insert identCurrentBugExeample(aChar) values('a')
--Print 2 because the last identity used is 2 print ident_current('identCurrentBugExeample') drop table identCurrentBugExeample
I found a strange problem with IDENT_CURRENT returning NULL value in all my SP's in which it is used.Following are the general reasons why it returns NULL :1. Its executed against the Empty table.2. Table does not Identity column.But i could check that above two point were not a prolblem for me. The problem was the database user has only db_executor permissions. If it is set to db_owner all my insert SP's work's as it should. But it fails otherwise.Can anybody throw some lights here ?
I have Server1(MSSQL7) & Server2(MSSQL 2000) are linked. For trigger purpose I need to access latest identity value from Server2.mydatabase.mytable in Server1 so I have statement as follows
Hi thereI have small problem with IDENT_CURRENT...We have a table where PK is generated automatically.What I want is to get that value and insert it to another,corresponding table.So here is what I am doing...BEGIN TRANInsert Into table() --> PK is created.SELECT IDENT_CURRENT('Table_Name') AS lastValueCOMMIT TRanIT works fine, but there is a possibility to insert another record byanother user before I get my IDENT_CURRENT.For instance:BEGIN TRANInsert Into table() --> PK is created.---->somebody else inserts another record into same table.SELECT IDENT_CURRENT('Table_Name') AS lastValue---->this is not the value that I generated....COMMIT TRan
I have a table that uses an identity column. I have a second column that will contain the current identity value or, when the original row is replaced, the identity value of the replacing row.
USE [test] GO /****** Object: Table [dbo].[test1] Script Date: 04/10/2008 14:04:22 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[test1]( [col1] [int] IDENTITY(1,1) NOT NULL, [col2] [int] NOT NULL, [col3] [varchar](max) NOT NULL, [ts] [timestamp] NOT NULL, CONSTRAINT [PK_test1] PRIMARY KEY CLUSTERED ( [col1] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO SET ANSI_PADDING OFF
My question is on the insert is it safe to use the following statement to insert the new identity value to the second column?
INSERT INTO test1 (col2, col3) VALUES (IDENT_CURRENT('test1'), 'test')
Hello, The following statement behave different between SQL2000 and SQL2005. On our database we have some insert statements like that, and as we test our DB for SQL2005, we have found this difference. Can anyone tell me why?
hi to all who is the best use among IDENT_CURRENT and @@IDENTITY and SCOPE_IDENTITY when i wnat to get last inserted id from a table. and also give the reason why because i am little bit confuse for useing these.. thanks in advance. arvind
Hi,can somebody explain me, why the IDENT_CURRENT from an empty table is 1?After insert of the first record it is still 1 (assuming that start valueis 1) which is okay. But if i check the IDENT_CURRENT from a newly createdtable the result should be NULL, or not?bye,Helmut
Hi I am trying to get the last ID value of a table. The following code worked when a SQLConnection object was used, how do I achieve the same result using an SQLDataSource? this.sqlSelectCmd2 = new System.Data.SqlClient.SqlCommand("SELECT IDENT_CURRENT('Assets')",sqlConnection1); sqlConnection1.Open(); int nID = Convert.ToInt32( this.sqlSelectCmd2.ExecuteScalar() ) ; nID++; dc.FocusedRow["ID"] = nID.ToString(); Cheers Pen
I have a SSIS package that imports data into a staging table from an excel sheet (This works fine). From the staging tabler i want it to insert the values into my members table, take that unique indentityID that gets created and insert the other values into other tables for that member that was just created.
In the staging table, i have all the values for a single member. But the structure of the database needs all the values inserted into seperate tables. There is no conditions ID in my members table, so the member first has to be created and from there i need to use the newly created member's MemberID and insert the conditions into a seperate table using the MemberID
I have created some sample data that can be used. I think i have an idea of how to do it, but i'm not totally sure if it will work that way, i have however included it in the sample data.
Code Snippet DECLARE @ImportedStagingData TABLE ( ID INT IDENTITY(1,1), Name VARCHAR(50), Surname VARCHAR(50), Email VARCHAR(50), [Chronic Heart Failure] INT, [Colon Cancer] INT ) INSERT INTO @ImportedStagingData VALUES ('Carel', 'Greaves', 'CarelG@Email.com', 1,0) INSERT INTO @ImportedStagingData VALUES ('Jamie', 'Jameson', 'JamieJ@Email.com', 1,1) INSERT INTO @ImportedStagingData VALUES ('Sarah', 'Bolls', 'SarahB@Email.com', 0,1) INSERT INTO @ImportedStagingData VALUES ('Bells', 'Scotch', 'BellsS@Email.com', 1,1) INSERT INTO @ImportedStagingData VALUES ('Stroh', 'Rum', 'StrohR@Email.com', 0,0) DECLARE @Conditions TABLE ( ID INT IDENTITY(1,1), Condition VARCHAR(50) ) INSERT INTO @Conditions VALUES ('Chronic Heart Failure') INSERT INTO @Conditions VALUES ('Colon Cancer') DECLARE @Members TABLE ( MemberID INT IDENTITY(1,1), Name VARCHAR(50), Surname VARCHAR(50), Email VARCHAR(50) ) DECLARE @memConditions TABLE ( MemberID INT, ConditionID INT ) SELECT * FROM @ImportedStagingData SELECT * FROM @Conditions SELECT * FROM @Members SELECT * FROM @memConditions /* --- This is the part that i am battling with --- DECLARE @CurrentValue INT DECLARE @numValues INT SET @numValues = (SELECT COUNT(ID) FROM @ImportedStagingData) WHILE @numValues <> 0 BEGIN INSERT INTO @Members SELECT Name, surname, email FROM @ImportedStagingData GO SET @CurrentValue = (SELECT IDENT_CURRENT('@ImportedStagingData')) INSERT INTO @memConditions (MemberID), (ConditionID) VALUES (@CurrentValue, --ConditionValue from @ImportedStagingData, all the values that have a 1)
Using SQL Server 2k5 sp1, Is there a way to deny users access to a specific column in a table and deny that same column to all stored procedures and views that use that column? I have a password field in a database in which I do not want anyone to have select permissions on (except one user). I denied access in the table itself, however the views still allow for the user to select that password. I know I can go through and set this on a view by view basis, but I am looking for something a little more global.
I am working http location and using sql server 2005 ,it is showing an error as " DELETE permission denied on object 'CourseDetails', database 'LOGIN', schema 'dbo'." CourseDetails is my table name and LOGIN is my database name.
I am trying to setup a BCP command in a stored procedure it workds for me an administrator. i'm using a user's account in the username and password in the BCP command of a user that has DBO rights on the database i'm extracting the dat from. I can execute the stored procedure from my workstation and the server using my login account in QA. Using the username of the dbo account in QA i can get it to work at the server but not at my workstation orher workstation. my thoughts were that it was network permission related but i bumped her account to that of a domain admin and it still will only work on the server. it generates the following error. The name specified is not recognized as an internal or external command, operable program or batch file.
this is what i'm executing with the names changed to protect the innocent
EXEC MASTER..XP_CMDSHELL 'bcp file_test..table_out out C:filej.txt -U username -P password -c' the environment is SQL7 on a 2000 Advanced server and we are running active directory.
i'm guessing it's something i'm just overlooking. i hope. any help would be most appreciated.
Hi , MY sysadministrator gave a sysadmin permissions to my login..,but i am not getting those permissions... when i check syspermissions system table it is showing my login id is having sysadming permissions... when we checked his machine , in security serverroles sysadministrators---properties--there it is showing my login-id.. but when i trying to click properties of servers it showing '' ONLY MEMBERS OF THS SYSADMIN CAN ACCESS THIS FEATURE'''' why it is happening pls let me know..
When I restore a database, I lose login permission and role permissions. I end up going into the login and unselect and reselect the database to make sure that the login works with the database. Is there a way to get around this??
One other question:: I have added 65 new tables to a database and want to give select only to all logins to those specific table -- is there an easy way of doing this???
WHat kind of permissions do you need to create a new job? It looks like I am the only one that can since I have full administator rights. So I created the job and then changed ownership to another user, but he cannot add a new step. WHen he tried to created a job he received message ERROR 229 EXECUTE permission denied on object 'sp_enum-Sqlagent_subsystem' database 'MSDB' owner DBO I gave the user access to MSDB as DBO but it didn't make any difference.
Can anyone help me with this problem? Is it possible for a user that runs one application against database A to update a table via a stored procedure i database B during runtime without beeing entered as a user in that database, i.e execute that stored procedure with a default or given user. The reason is that we don't want to administrate an unknown number of users that will have no access to that database except via that stored procedure.
what does it meant if I go and look at the permissions on a user and in one item (say a stored procedure) there is a green check giving permissions but the check cannot be removed. How can I remove that?
What are the minimum permissions required to be able to read the application log in the event viewer & run perfformance monitor? Do you have to have NT admin rights on the server? thanks!
To all, I need some help understanding some things about SQL permissions. Login ID A is a login mapped to the dbo of database A and B. Login ID B is aliased to dbo. Why when running a transfer from database A to B, it runs OK when run by Login A, but fails as Login B. In the failure situation, I get error 15244, only sa or dbo can set database permissions. I thought by virtue of the aliasing I had dbo permissions. This SQL stuff is more confusing than any TCP/IP or Cisco stuff I have ever done.
1) Administrator access to the local box on running SQL 2) The ability to access the SQLData directory directly through drive mappings
We are attempting to create as secure an environment as possible and keep everything locked down. In my opinion, they do not need these type of accesses. They do have sa priviliges to the SQL server but I see no reason to give them Windows 2000 administrator priviliges. Also, to further the security on the servers (they are publicly accessible), we are trying to eliminate all shares including admin shares. Seems to me they should be able to accomplish everything using the SQL tools. Am I off base on this?
I have a database with sql as the engine and access is on the client side. my problem is that when more then one person gets into the database it comes up read only. They are on sql as a users, not sure whats going on
I'm developing a DTS package which will be scheduled and will write files out to a LAN share. When I execute the package manually from enterprise manager it works just fine. But when scheduled..fails with a access denied. Can someone point me towards the area I need to fix this? I'm running the SQL server under the System account.
I have a vendor that needs to remote in to our SQL 2005 Enterprise server and connect to their database. I have created them a username and password in SQL and they can VPN into our network and connect to their database using Management Studio just fine. So far so good! The issue is this: They need to be able to see the processes of an application that connects to their database. When they run 'sp_who2' all they can see is themselves running 'Management Studio'.
What else do I need to give them permission to in order for them to see all processes that are tied to their database? I need to do this without giving them permissions to other databases. I have several databases on this server.

Q 3
I have a SP names YourSP and have the a select stmt inside the SP. I also have a user named YourUser.What permissions i have give him for accessing the SP ?"
I have a bunch of sp's I need to push out to the server. I need to grant permissions to each so that the calling application will be able to execute them. I currently open each one, and manually add the user permission. Is there a script that i can run that will do this (there are over 100 sp's) Thanks
