Return @@identity For Another Function

May 14, 2004

What I'm trying to do is provide a solution where users can upload an image and a description, to a database, so I'm trying to insert the title and description then return the @@identity for the image upload function which will name the image like this
image_23.jpg (23 being the @@identity) resize it and save it to specified directory

I cant seem to get the identity to return to my script.
This is my SP

CREATE PROCEDURE SP_Insertad
(
@catid int,
@subcatid int,
@areaid int,
@uid int,
@adtitle varchar(255),
@addescription varchar(1000)
)

AS
Insert Into Tbl_ad
(ad_title, ad_description,ad_area,ad_ui_id,ad_active,ad_date,ad_ct_id,ad_sc_id,ad_location)
VALUES
(@adtitle,@addescription,@areaid, @uid, 0,convert(varchar, GETUTCDATE(), 101), @catid, @subcatid, 1)

select @@identity
return
GO


I tested in query analyser, and it works fine, so It must be my code. this is my function

Sub Insert_pic(sender as object, e as eventargs)

Dim catid = Request.form("ddcats")
Dim subcatid = Request.form("subcatrad")
Dim adtitle = Request.Form("txttitle")
Dim AdDescription = Request.form("txtdescription")
Dim uid = getUID(Context.User.Identity.Name)
Dim areaid = Request.form("ddarea")
SQLConnect = new SqlConnection(ConfigurationSettings.Appsettings("mydB"))

SQLCommander = New SQLCommand("SP_INSERTad", SQLConnect)

SQLCommander.Commandtype = Commandtype.StoredProcedure

SQLCommander.Parameters.add("@adtitle", adtitle)
SQLCommander.Parameters.add("@addescription", addescription)
SQLCommander.Parameters.add("@catid", catid)
SQLCommander.Parameters.add("@subcatid", subcatid)
SQLCommander.Parameters.add("@uid", uid)
SQLCommander.Parameters.add("@areaid", areaid)

'// this section not working right, it wont write return id

Dim paramreturn as SQLParameter
paramreturn = SQLCommander.Parameters.Add("ReturnValue", SQLDBType.Int)
ParamReturn.Direction = ParameterDirection.ReturnValue

response.write(SQLCommander.Parameters("ReturnValue").Value)

SQLConnect.open()
SQLCommander.ExecuteNonQuery()
SQLConnect.close()

End sub

Can anybody see anything I missing? I appreciate any imput

Return Identity In Stored Procedure

Mar 23, 1999

I have a stored procedure where I am passing in several strings which are concatenated to form an Insert SQL statement. I then return the identity value from the insert - problem is, the identity value is coming back NULL.

Here is the sp. Any ideas?

CREATE PROCEDURE sp_ExecuteInsert
@pIdentity int OUTPUT,
@pSQL1 varchar(255),
@pSQL2 varchar(255) = NULL,
@pSQL3 varchar(255) = NULL,
@pSQL4 varchar(255) = NULL,
@pSQL5 varchar(255) = NULL,
@pSQL6 varchar(255) = NULL,
@pSQL7 varchar(255) = NULL,
@pSQL8 varchar(255) = NULL
AS

EXECUTE (@pSQL1 + @pSQL2 + @pSQL3 + @pSQL4 + @pSQL5 + @pSQL6 + @pSQL7 + @pSQL8)

SELECT @pIdentity = @@IDENTITY
GO

FYI, the real problem I am trying to solve is simply to return the identity after an insert. I could write a simple insert sp that returns the identity, but my code is written to handle generic situations and build an INSERT statement as needed. So if there are any other ideas of executing an insert statement and getting the identity, please let me know.

Thanks...

Return The Lastest [Identity] Field Value

Feb 17, 2004

Hi!

I have a question that might sound obvious to some of you but (obviously) not to me.

I have a stored procedure that adds a new record to a table that has an [Identity] field (TableID).

I want to return the value of the TableID of the newly created record. Sound simple ?

Thanks.

How To Use Identity On Non-identity Column (with Concurrence)

Aug 1, 2014

I'm working with a third-party database (SQL Server 2005) and the problem here is the following:

- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).

- The PK of T is an Integer.

Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.

Considering that I can't change the PK, what is the best approach to solve this problem?

To sum up:

* I need to have processes in parallel inserting on T

* I can't change anything on T

* The PK is NOT an Identity

SP Syntax Help - Return New Identity Value As Output Param

Feb 4, 1999

I have a stored proc that will insert a new row into a table
with the values of the parameters you pass in. I need it to
return the value of the ID that's generated by an Identity
column once the row has been written and that value has
been generated. If I just do a SELECT Max(), I could
accidentally grab a row written by someone else, right?

My current sp looks like this:

CREATE PROCEDURE sp_SaveNewLabel

-- @LabelID int output
@LabelType int
, @Logo int
, @Field01 char(30)

AS

INSERT INTO tbLabel
(LabelType
, Logo
, Field01)

VALUES
(@LabelType
, @Logo
, @PrintCC
, @Field01)


How do I grab the new LabelID (the column is int, Identity) and return
it from the stored proc. Any help would be greatly appreciated...

Problem With @@identity Return In Stored Procedure Insert.

Nov 24, 2003

I'm having a problem I do an insert into a table but I want to return the value of the identity field of that insert so I can email a confirmation. For some reason this code doesn't work.
Below is the stored procedure I'm calling and below that the code I'm using. What am I doing wrong. The value I have returned is null when it should be a number. Any suggestions. Why does finalMagicNum2 come back null when it should grab the identity field of the inserted record.




CREATE PROCEDURE addMagicRecTest
(
@theSequence int,
@theSubject int,
@theFirstName nvarchar(50)=null
@theLastName nvarchar(75)=null
)



AS

INSERT INTO employees([Sequence],subject,firstname,lastname)
VALUES(@theSequence,@theSubject,@theFirstName,@theLastName)
SELECT @@identity AS finalNum



magicDataConnect = ConfigurationSettings.AppSettings("myDataConnect")
Response.Write(magicDataConnect)
magicCommand = New SqlDataAdapter("addMagicRecTest", magicDataConnect)
magicCommand.ConnectionType = CommandType.StoredProcedure
magicCommand.SelectCommand.CommandType = CommandType.StoredProcedure

' Sequence ID for request
magicCommand.SelectCommand.Parameters.Add(New SqlParameter("@theSequence", SqlDbType.NVarChar, 8))
magicCommand.SelectCommand.Parameters("@theSequence").Value = "41833"

' Subject for new Wac Ticket
magicCommand.SelectCommand.Parameters.Add(New SqlParameter("@theSubject", SqlDbType.NVarChar, 8))
magicCommand.SelectCommand.Parameters("@theSubject").Value = "1064"


' First Name Field
magicCommand.SelectCommand.Parameters.Add(New SqlParameter("@theFirstName", SqlDbType.NVarChar, 50))
magicCommand.SelectCommand.Parameters("@theFirstName").Value = orderFirstName

' Last Name Field
magicCommand.SelectCommand.Parameters.Add(New SqlParameter("@theLastName", SqlDbType.NVarChar, 75))
magicCommand.SelectCommand.Parameters("@theLastName").Value = orderLastName



DSMagic = new DataSet()
magicCommand.Fill(DSMagic,"employees")

If DSMagic.Tables("_smdba_._telmaste_").Rows.Count > 0 Then
finalMagicNum2 = DSMagic.Tables("_smdba_._telmaste_").Rows(0)("finalMagic").toString
End If





I need finalMagicNum2

Hi all,

The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..

ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id)
REFERENCES parent_table (parent_id) ON DELETE CASCADE

the error thrown is :
Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT

CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be

Identity Column - DTS

Mar 27, 2001

Having an identity column in target table, how do I use SQL 7 DTS ?

In Import wizard, I chose 'ignore' in source, checked Enable Indenity Insert - DTS failed with a msg like - a column cannot have NULL...

In DTS package, had Fast load and Enable Indenity checked - no luck !

Unchecked Enable identity, do luck.

What would be the standard procs for this since this sounds like a very common
senario.
What I am expecting is to insert from source and SQL would take care identity column automatically.
Appreciate your help very much !

Identity Column

Feb 29, 2000

I have a table that has a field that will not accept null values. I was trying to create a new table with a new field that would accept null values. I would then drop the original table and rename the new table. The problem is my key field has the Identity column (Autonumber) turned on. This allows the recordID to be automatically generated. Is there anyway to bypass the Identity Column feature and still keep it there future records? I already tried the "with Nocheck Clause" but does not work.
