How Do I Retrieve The IDENT_CURRENT Value Of A Table Using An SqlDataSource?
Dec 8, 2005
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

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 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)
@numValues = @numValues - 1
END
END
*/
All help will be greatly appreciated.
Kind Regards

Background:I am using Visual Studio 2005 Standard SP1 to create an ASP.NET website that accesses an SQL 2005 database. I am using vb.net as well.I am passing an ID in a query string from one page to the next, where I retrieve it using an SQLDataSource. The data will only be one row; it is returning customer information.Problem:I need to be able to get specific fields from the SQLDataSource and populate some textboxes. Honestly, I'm not really sure where to begin. For the sake of argument, let's say that I am working with this:'My TextboxDim LastName As Textbox'My SQLDataSource (filtered by query string using the customer's ID to only get 1 customer's information at a time)SQLDataQuestion:So, how would I go about retrieving the lastname field from SQLData and inserting it into the textbox LastName?Thanks, J'Tok

I'm an "old" programmer but new to ASP.NET.
I want to get a value from the SQL Dataset.
What I would normally do in other environments is iterate through the dataset to get the value I would be intrested in, but I can't figure out how to do this without using a visual data display object like a Grid view.
Typically I want to get a value from the database that I then after manipulating it, like multply by 5, use to format something on the page.
thanks in advance,
Thommie

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
Felix Pageau

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 ?

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')

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
any info much appreciated

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?
create table #tmp (a int identity(1,1), b int)
insert into #tmp
values(ident_current('#tmp'))
select * from #tmp
insert into #tmp
values(ident_current('#tmp'))
select * from #tmp
drop table #tmp

In Master tabel i have these date datas
2015-05-10
2015-05-11
2015-05-12
SO when i try to load from  Master table to parent and child table i am using using expresssion likeÂ
select B.ID,A.* FROM FLATFILE_INVENTORY AS A JOIN DMS_INVENTORY AS B ONÂ
A.ACDealerID=B.DMSDEALERID AND A.StockNumber=B.STOCKNUMBER ANDÂ
A.InventoryDate=B.INVENTORYDATE AND A.VehicleVIN=B.VEHICLEVIN
WHERE convert(date,A.[FtpDate]) = convert(date,GETDATE()) Â and convert(date,B.Ftpdate) = convert(date,getdate()) ;
If i use this Expression i am getting the current system date data's only  from Master table to parent and child tables.
My Problem is If i do this in my local sserver using the above Expression if i loaded today date and if need to load yesterday date i can change my system date to yesterday date and i can run this Expression.so that yeserday date data alone will get loaded from Master to parent and  child tables.
If i run this expression to remote server  i cannot change the system date in server.
while using this Expression for current date its loads perfectly but when i try to load yesterday data it takes current date date only not the yesterday date data.
What is the Expression on which ever  date i am trying load in  the master table  same date need to loaded in Parent and child table without changing the system Date.

I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database.
I have a very simple dilemma. In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields.
It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table.
In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters.
The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%')
If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null>
My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>.
For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null> (accounting for about 95% of the records in the database). Thanks in advance Simon

Here's my table:
tblOrders
----------------
OrderID | Total
----------------
I'd like to get the Total value out of the table if I'm given the OrderID, and store it in a variable. I'm using C# and ASP.NET 2.0.
It's probably really simple, and I think I need to use a stored procedure and ExecuteScalar(), but I'm not sure how to do it.

I am more familiar with writing SQL for Oracle than MS SQL Server. Within Oracle there is a simple command, 'Describe', which actually shows the data types, and whether or not an attribute accepts NULLS. MS SQL Server does appear to support such a command, however I am looking for a way to describe the attributes of tables nonetheless.

Hi, everione,
I am having a big problem, trying to create datebase.
I have 3 tables: SUPERAVATAR, MASTERAVATAR, MEGAAVATAR.
- SuperAvatars are heroes in an online role playing gaming. They have an ID, ‘superavatarID’ which contain an UNIQUE NUMBER NOT NULL PRIMARY KEY to identify them.
A wisdom – ‘trickster’,’conjuror’,’magician’, etc..
A current owner… who is the user or player of the game and has that Super Avatar– we associate the link to USERID to know the person.
SuperAvatars can be fathers or mothers of Mega Avatars.
-MegaAvatars are the children of SuperAvatars…. They also have an ID UNIQUE NUMBER NOT NULL PRIMARY KEY to indentify them.
A magic power – it can be a ‘Leader’ or ‘Sheep’…
A ‘parent’ – parent is the number identifying to know to who Super Avatar belongs.
e.g.
SUPERAVAT WISD CURRENTOWNER FATHEROF MOTHEROF
1 Thick 3 1
2 Mentally Ch. 11 3
3 Smart 9 2
4 Genius 16 4
5 Thick 19
MEGAAVATARID MAGICPOWER PARENT
1 MAGICIAN 1
2 WIZARD 3
3 SORCERER 2
4 MAGICIAN 4
-We see that MEGAAVATAR 1 has a magic power as Magician and his father is ‘1’. ‘1’ identifies the SUPERAVATAR.
We see SUPERAVATARID…. who has the number ‘1’? the first in the row… who has wisdom – thick and he belongs to the USER with ID number 3.
-We see MEGAAVATARID… we choose the number 2…. His magic power is as WIZARD… and his father is the number 3.
We see SUPERAVATARID now… we look up the SuperavatarID 3…. We can see he has a wisdom – GENIUS… who belongs to the USERID 16 and he is father of MEGAAVATAR number 2.
The list can carry on and never stop.
I have this Problems:
We create in this example 3 tables: Users, SuperAvatar, MegaAvatar
SQL
CREATE TABLE users(userID NUMBER CONSTRAINT pk_user PRIMARY KEY,email VARCHAR2(50) NOT NULL UNIQUE,password VARCHAR2(15) NOT NULL UNIQUE,subscription CHAR(8) NOT NULL CHECK (subscription IN('ACTIVE' , 'INACTIVE' ) ) );
CREATE TABLE superavatar(superavatarID NUMBER CONSTRAINT pk_superavatar PRIMARY KEY, wisdom VARCHAR2(19) NOT NULL CHECK (wisdom IN ('THICK', 'MENTALLY CHALLENGED', 'AWAKE', 'SMART', 'GENIUS')), currentOwner NUMBER NOT NULL, fatherOf NUMBER,motherOf NUMBER);
CREATE TABLE megaavatar (megaavatarID NUMBER CONSTRAINT pk_megaavatar PRIMARY KEY, magicPower VARCHAR2(12) NOT NULL CHECK (magicPower IN('TRICKSTER','CONJUROR','MAGICIAN','WIZARD','SORCERER')), parent NUMBER);
Now, the 3 tables are created…..
What happen when we try to insert values to this table?
In this case we insert to User Table some examples:
INSERT INTO users VALUES('3','john@hotmail.com','great78','ACTIVE');
INSERT INTO users VALUES('9','chrisandsandra@gmail.com','chrisandra)','ACTIVE');
Now, we insert to SuperAvatar some examples;
INSERT INTO superavatar VALUES('1','THICK','3','1','');
INSERT INTO superavatar VALUES('3','SMART','9','3','');
|
|
‘9’ is the UserID that we already insert to the User table
What’s the problem?
We have to insert manually the data from USERID to CURRENTOWNER as we didn’t match or link CURRENTOWNER from SUPERAVATAR Table to USERID from USER Table with a SQL CODE.
What happen if we have thousands of USERS that they register to this game…? We will never know to how belongs that SUPERAVATAR but if someone do it manually can spend a year.
I am trying to fix this problem …. I add in SUPERAVATAR TABLE ‘CHECK’ in currentOwner..
SQL> CREATE TABLE superavatar
(superavatarID NUMBER CONSTRAINT pk_superavatar PRIMARY KEY, wisdom VARCHAR2(19) NOT NULL CHECK (wisdom IN ('THICK', 'MENTALLY CHALLENGED', 'AWAKE', 'SMART', 'GENIUS')),
currentOwner NUMBER NOT NULL CHECK (currentOwner IN(SELECT userID FROM users)),
fatherOf NUMBER,
motherOf NUMBER);
*
ERROR:
ORA-02251: subquery not allowed here
It doesn’t work.
Please HELP, I have exam tomorrow
thank you
Desy
