View 18 RepliesAfter making several hundred queries against a SQL CE 2.0 database (through NetCF/ADO.NET), I begin getting a SqlCeException: "Not enough storage is available to complete this operation."
Microsoft speaks to this situation in the following hotfix:
http://support.microsoft.com/?kbid=827837
When I contacted them to receive the hotfixed ssce20.dll, they described the problem as SqlCeDataReader and SqlCeDataAdapter not releasing their memory resources after they went out of scope. In addition to using the hotfixed binary, they also advised me to call SqlCeEngine.Dispose() after every query to force SQL CE to release resources, as shown in the "finally" block of the code below.
I have a couple of questions about this:
(1)
Will this cause a lot of performance overhead for me, especially if my application makes frequent queries using the following code?
(2)
Can a cache an instance of SqlCeEngine and call Dispose() on that cached instance repeatedly, so I can avoid having to instantiate a new SqlCeEngine each time?
SqlCeConnection conn = null;
try
{
conn = new SqlCeConnection(connectionString);
dbCmd.Connection = conn;
dbCmd.Connection.Open();
dbCmd.ExecuteReader(CommandBehavior.CloseConnection);
<use the reader>
}
finally
{
dbCmd.Connection.Close();
// Add the following code to release resources?
SqlCeEngine engine = new SqlCeEngine(connectionString);
engine.Dispose();
}
Hi,
We are planning to use the BTS BRE for our business rules and calling these from a data flow transformation (e.g. for every row in a flat file during import). One way would be to use a script component.
However, the question is that the script component would have to create and destroy BRE objects (e.g. a BRE Policy object) for every row in the flat file.
Is there a way to instantiate objects and whole on to them for the lifetime of the package or a container within a package?
Any suggestions regarding achieving the above most efficiently would be much appreciated.

Hello,
I am trying to test a simple trigger on insert and it does not work when I call EXEC sp_send_cdosysmail.
However, the stored procedures does work if I right-click on it and select Execute Stored Procedure.
Below is a simple version of the trigger I am trying to implement. I know it works in SQL Server 2000 and 2005 but can't seem to get it to work in SQL Server 2005 Express. Any help is greatly appreciated!
ALTER TRIGGER [dbo].[trig_Tableinsert]
ON [dbo].[Table]
FOR INSERT
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from

Print 'Hello'
-- Insert statements for trigger here
EXEC sp_send_cdosysmail some@one.com', 'notify@me.com','New Insert', 'test'
END
Thanks!
I've been searching for a bit but I can't seem to find a difinitive answer.
Can an SQL Server trigger call native C/C++ functions? If so, what is the mechanism?
Thanks in advance.
hi,
when calling an SSIS package from a trigger causes it to run for ever. Know why??
In Detail;
Consider that there are two tables with the same schema in a db. Lets name that Test1 and Test2.
I develope a package whihc will transform data from Test1 to Test2. I initiate this package from a Trigger for Insert on Test1. For eg.
CREATE TRIGGER Trigger_Test1
ON Test1
AFTER INSERT
AS
BEGIN
EXEC xp_cmdshell 'dtexec /FILE "C:TestTestPackage1.dtsx"'
END
This runs for ever when a record is inserted into the Test1 table.
But, when the trigger is on someother table , everything works fine.For eg, if the trigger is on the table TT1 & this trigger initiates the same package while inserting a record into TT1, everything is fine.
Can anyone help me on this.
Thanks

I have to control my business rules in a Instead of Insert, Update Trigger.
Since the Control Flow is quite complicated I wanted to break it into stored procedures that get called from within the trigger.
I know that Insert Statements embedded in a Instead of Trigger do not execute the Insert of the trigger you are calling.
But... If I embed stored procedures that handle my inserts in the Instead of Insert trigger call the trigger and put in a endless loop or are the stored procedure inserts treated the same as trigger embedded inserts.
I am looking to create a server wide trigger which will fire whenever a database gets created, I would like to know if there are any gotchas or anything that I need to look out for/test specifically.
The idea is to automatically grant some permissions and take some other actions whenever a database gets created.
I have a after update trigger that calculates one of the columns based on other column values. It has to be a trigger and only fires an update statement against the table itself when the column has changed. At a simple level it is doing something similar to the code below
IF UPDATE(Col1)
update MyTable SET Col2 = Col1 WHERE Col2 <> Col1
It works everywhere except on one site where the trigger causes itself to recurse until it reaches the 32 level error. It can be fixed by checking whether there and any records in the inserted table at the top. Like so.
IF EXISTS (SELECT * FROM inserted)
begin
IF UPDATE(Col1)
update MyTable SET Col2 = Col1 WHERE Col2 <> Col1
end
However, I would like to know whether there is some system setting other than "nested triggers"Â that I am missing that would cause the behaviour.
we have a table in database , which has multiple triggers defined by Vendor. I have created our own custom trigger on this table also , which fires last. Goal of this custom trigger is to send an email, when ever update happens on table. But somehow trigger is firing multiple times for same update, so it is sending multiple email for same update also

View 4 Replies View RelatedHey,
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.

I want to be able to create a trigger so that when a row is inserted into table A by a specific user then the ID will appear in table B. Is it possible to find out the login id of the user inserting a row?
I believe the trigger should look something like this:
create trigger test_trigger
on a
for insert
as
insert into b(ID)
select i.id
from inserted i
where

View 4 Replies View RelatedHi,
I am not sure if this is the right forum to post this question.
I run an update statement like "Update mytable set status='S' " on the SQL 2005 management Studio.
When I run "select * from mytable" for a few seconds all status = "S". After a few seconds all status turn to "H".
This is a behaviour when you have an update trigger for the table. But I don't see any triggers under this table.
What else would cause the database automatically change my update?
Could there be any other place I should look for an update trigger on this table?
Thanks,
Hi all in .net I've created an application that allows creation of triggers, i also want to allow the deletion of triggers.
The trigger name is kept in a table, and apon deleting the record i want to use the field name to delete the trigger
I have the following Trigger
the error is at
DROP TRIGGER @DeleteTrigger
I'm guessing it dosen't like the trigger name being a variable instead of a static name
how do i get around this?

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

Hi all, i have a DTS package that i call from a C# app, i had it working great until i decided to use an activeX script to do the data transformations instead of the row copy. I need to use ActiveX to add a standard name to the last column in the destination table. the problem is the task is executing without errors (from c#) but nothing is happening, its failing silently. If i modify the Data Transformation back to a standard column mapping (with separate DTSTransformations for each column) it works fine, but as soon as i use activeX to handle the transformations it doesn't work. Can anyone tell me what i may be doing wrong. heres the calling code from C# if(f.Name.Substring(13,7).ToLower() == "product")
{
try
{
activity.Log("Starting Product DTS Package...");
DTS.Package2Class package = new DTS.Package2Class();
object pVarPersistStgOfHost = null;

package.GlobalVariables.Item(1).Value = f.FullName.ToString();
package.Execute();
package.UnInitialize();
//force release of COM object
System.Runtime.InteropServices.Marshal.ReleaseComObject(package);
package = null;
}
catch(Exception e)
{
activity.Log(string.Format("Failureprocessing {0}",WorkingPath + f.Name) +" - "+ e.Message);
} and the activex i tried to use for the transformations is: '**********************************************************************' Visual Basic Transformation Script'************************************************************************' Copy each source column to the destination columnFunction Main() DTSDestination("Yesmail Id") = DTSSource("product series") DTSDestination("Customer CKM CustId") = DTSSource("product family") DTSDestination("Product SKU") = DTSSource("transaction date") DTSDestination("product model name") = DTSSource("serial number") DTSDestination("serial number") = DTSSource("product model name") DTSDestination("transaction date") = DTSSource("Product SKU") DTSDestination("product family") = DTSSource("Customer CKM CustId") DTSDestination("product series") = DTSSource("Yesmail Id") DTSDestination("fileName") = DTSGlobalVariables("sourceFile").Value <-- this is why im using the activex for this field to get a Global Variable.
