Hi,
A need a trigger to scope my data modifications but this code return EventData a NULL. Can someone help me with this?
Thanks

I have taken three dtsx files and re written them into one each in its own container. I use the XML Task task alot which the File connection is set by a variable and the variable value is evaluated by expression (the expression makes up the path/filename from other variable values). All the variables that make up the connection are at the container scope. The package will not run now because it is saying that the source (created by variables) for the file connection do not exist.
It seems the answer is that file connections exist at the package level therefore the variable has to be at the package level. This seems to be alot of variables i now have to move to package level to generate the XML source connection. Which in essence makes it confusing as to which variables operate in which container.
My question is can we easily move variable scope (Not ideal as we have alot of variables at package level) Or Can we do the same for connection managers as we do for variables and have them only used in a scope? (this will be ideal as some connections only need to be at a container scope)

In my sp I'm have an Insert statement. In the event that after the insert @@rowcount = 0 I'm throwing an error with RAISEERROR.
This is fine, however, in my CATCH block I'm referencing a local temp table but getting an error that it no longer exists.
My question is, does throwing an error drop any #temp tables? I thought they were in scope for the session?

if a dataset doesnt use a stored proc to define a table variable, what is the scope of that table variable? Does the name need to be unique from such variables defined by other datasets?

I have a query which is part of bigger transaction:
;WITH CTE(
SELECT id, q,
totalQ=SUM(q) OVER (ORDER BY id ROWS UNBOUNDED PRECEDING)
FROM dbo.myTable WITH (UPDLOCK, ROWLOCK)
), CTE1 AS(
SELECT id, q_take=CASE WHEN c.Total<@qRequired THEN c.q ELSE
@qRequired-c.Total+c.q END FROM CTE
WHERE (CASE WHEN c.Total<@qRequired THEN c.q ELSE
@qRequired-c.Total+c.q END)>0
)
UPDATE t set q-=c1.q_take FROM dbo.myTable t INNER JOIN CTE1 c1 ON t.id=c1.id
Because CTE query is executed separately of update query I must put UPDLOCK hint, otherwise myTable could be changed while my query executes by some other user.(I have snapshot row committed transaction).
The problem is that my hint will hold lock on rows of myTable until the end of outer transaction(the bigger one).
But I need lock only for the time of this small query execution. What would be the best way to achieve that?

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

I am generating some dynamic sql which I would like to run and return the data from, however when I run EXEC(@TEMP_TABLE_STRING) it cannot return the table I think because it is out of scope.
Is there a way around this.
declare@Tablename VARCHAR(150) = 'TEMP_LOCATIONS'
declare@FilterClause VARCHAR(512)=NULL
declare@Classes VARCHAR(100)=NULL
declare@IsExcel BIT = 1
DECLARE @SQL Nvarchar(MAX) = ''

Hi,
I have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out
and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up
Any thoughts?
Here is my t-sql
Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)
select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d
where i.req_guid = d.req_guid
and i.req_fname <> d.req_fname
Thanks,
leo

what are some common techniques for ensuring an isolated temp table scope? For example, if 2 different sprocs happen to crud a temp table with the same name? I'm guessing that big SQL shops establish a standard for this early on to avoid conflicts between sprocs.

Hey,
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with:
WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc.
Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below)
Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending
Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government]
Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc.
Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies.
Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Thanks.

The trick was getting the Table Name and the Primary Key Columns.
I hope this code is found useful.
Comments and Suggestion will be much appreciated.

I believe the trigger should look something like this:

as
insert into b(ID)
select i.id

I want to insert a row for a Global user in Table 'A' whenever ADO.Net code inserts a Local user row into same table. I recommended using a trigger to implement this functionality, but the DBA was against it, saying that stored proecedures should be used, since triggers are unreliable and slow down the system by placing unecessary locks on the table. Is this true OR the DBA is saying something wrong? My thinking is that Microsoft will never include triggers if they are unreliable and the DBA is just wanting to offload the extra DBA task of triggers to the programmer so that a stored procedure is getting called, so he has less headache on his hands.Thanks

I want to pass the 'inserted' table from a trigger into an SP, I think I need to do this by dumping inserted table into a temporary table and passing the temp table. However, I need to do this for many tables, and don't want to list all the column names for each table/trigger (maintenance nightmare).
Can I dump the 'inserted' table to a temp table WITHOUT specifying the column names?

Hi folks
I'm using a function to create a record on a database, and then I want to return the ID of that record to passinto another function. I believe its scope identity that does this, but I'm not sure how to do it. public static void putrecordin(string record) { SqlCommand cmd = new SqlCommand("insert Table (record) values (@record; scope identity)" conn.Open(); cmd.Parameters.Add(new SqlParameter("@record", record)); cmd.ExecuteNonQuery(); conn.Close(); another(new-record-ID, anothervalue); } public static void another(string new-record-ID) {do stuff
}
so you'll see I have a function called putrecordin, and at the end of the sql statment I want to return the id of the new record and pass it into another function called another.
Anyone know how to do this?
Thanks!

<MEP MEPName="Test Combining PIFs" MEPType="Close" PIFRecId="13" IsPrimaryPIF="0"><AssignedTo>X000525</AssignedTo></MEP>
</PifToMepData>
I then use
INSERT INTO #myTemp99 (

, MEPType
, PIFRecId
, IsPrimaryPIF
, AssignedTo)
SELECT *

,PIFRecId int '../@PIFRecId'
,IsPrimaryPIF varchar(20) '../@IsPrimaryPIF'
,AssignedTo varchar(20) '.'
)
To Parse it out. This then has to be inserted into another table with an identity column (damn Identity column), and I need to grab the generated id for each row, because then there are other children tables that need to be populated.
Question: Is there any set way to grab multiple generated id's?
Or do I need to loop or use a cursor?
Is the 1% of the time that they are needed?
Any ideas?
Here's the temp table DDL
CREATE TABLE #myTemp99 (

I've been trying to figure out the usage of "Nothing" as the scope parameter, and the more I try, the more I can confused.
It says on the RDL spec:
"For expressions inside data regions:
.......
Specifying the keyword Nothing as the scope is equivalent to specifying the
outermost data region containing the report item in which the aggregate is used."
It seems that what's it saying is that if I have an expression in a table as
= last(somefield, "the name of the table")
is the same as
= last(somefield,Nothing)
But, apparently it;s not. (I tried last, first,sum, count,CountRows, min, max...........)
it doesn't matter where I put "=last(somefield,Nothing)" in the table (i tried table header,footer, detail, and table group header, footer), none of them worked.
and I tried it everywhere in matrix, in charts.
It's just not working.
It always complains about the invalid scope not being the containing data region, containing grouping or dataset name.
However, the only way I get the "Nothing" as the scope to work is in a RunningValue function, not in any other
aggregate funcitons.
Anyone help me with this, please... I need a complete definition on the usage of Nothing as scope.

I am really starting to like CTEs. My only qualm is that you can only use them within the first statement after you declare them. I wish they would remain active for the duration of the sql batch just like everything else (variables,local temp tables, ect). Is there any trick so that you can use them multiple times? Maybe define them as a string and do dynamic sql or something like that? Hopefully (i have not researched the new version of sql server) in SQL Server 2008 the scope has increase. Anyways any help would be appreciated.
thanks,

.Add(New SqlParameter("@kredit", kredittext))
.Add(New SqlParameter("@ptext", ptext))
End With
Cmdpost.ExecuteNonQuery()
Next
MyConn.Close()
In other words, the verid is the id of the new post in the first table. This id should be inserted in the new table as well.
Thank you very much in advance fro helping me out! I've worked a LONG time with this.

Is it possible to write the InsertCommand for a SqlDataSource to return the value of the AUTONumber of a field generated when a new record is added to a database table and display that value on label1.Text after the postback of ItemInsersted event? For example, <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NearMissConnectionString >" InsertCommand="INSERT INTO [NearMiss] ([Branch], [Division] VALUES (@Branch, @Division); SELECT SCOPE_IDENTITY()" SelectCommand="SELECT [NearMissID], [Branch], [Division], FROM [NearMiss]" <InsertParameters> <asp parameter Name="Branch" Type="Int32" /> <asp parameter Name="Division" Type="String" /> </InsertParameters>
</asp:SqlDataSource>
NearMissID would be the value of the autonumber generated by the SQL Server
