Values in my database need to updated periodically. The code, upon starting the application, queries the database and stores the values in the Application collection. This is to avoid making a database call everytime the values are needed (increases performance). The drawback is that changes to the database values are not updated in the code.
How can I create a database trigger that will update the C# Application colllection whenever a table value is updated?
I have a SQL Server project in Visual Studio 2005 which deploys an assembly to SQL Server 2005 containing various stored procedures user defined functions. Is there any way to tell Visual Studio to drop/create the stored procedures in a schema other than dbo?
ie: User.ChangePassword instead of dbo.ChangePassword.
Are there any additional documents or utilities that people would suggest for monitoring and managing CLR impact on SQL server resources and performance?
Our current service throws on-demand .DTSX and now we'd like that will throw old ETL 2000 too.
I'd like to know if success or not success when calling dtspkg.dll from my managed code (vb). Is it possible or not? I only capture errors for the sake of TRY..END TRY but I don't know how the hell to know if the dts execution was successful. Execute method not returns anything.
SQL Server 2005 gives you a possibility to create managed triggers. In a managed trigger I can create a new thread and process trigger event in various ways. My question is that are there any reasons why I should NOT start new threads in database triggers? The following code shows how I could create new threads. Do you see that this could cause any errors or problems in SQL Server functionality? My goal is to minimize the trigger effects in a database overall performance.

Code creates the Temp table but when it comes to insert statement, it throws error saying "Temp table not found". Reason can be Create and Insert statement gets executed as 2 different sessions. How to get the above requirement work fine? Thank you. HV
The result is that I am able to parameterize the sql end execute with the right result. The only problem is that the value is not stored in the variable @count. I could get to the same result using managed code in sql 2005 but still I am curious to find out where the problem is ....
All -- Please help. I am using managed code in SQL Server 2005 and have a question about stored procedure name qualification. With a VS.NET 2005 Pro Database project, when I use >Build, >DeploySolution, it works great but my stored procedures are named with qualification using my domainusername.ProcName convention, something like this... XYZ_TECHKamoskiM.GetData ...when I want them to be named with the dbo.ProcName convention, something like this... dbo.GetData ...and I cannot see where this can be changed. Do you happen to know? Please advise. (BTW, I have tried going to this setting >Project, >Properties, >Database, >AssemblyOwner, and putting in the value "dbo" but that does not do what I want.) (BTW, as a workaround, I have simply scripted the procedures, so that I can drop them and then add them back with the right names-- but, that is a bit tedious and wasted effort, IMHO.) Thank you. -- Mark Kamoski
1) first i installed Sql Server 2005 Enterprise Edition, everything was working fine except i was not able to create managed objects from BI, like stored procedures, triggers, UDT, etc etc.
2) so i installed VS.net 2005 complete + Sql Server 2005 Express Edition
now i was able to create stored procedures, triggers, etc etc, i'm talking about the CLR objects, ok, i.e. the managed code, but........ i was only able to do this from Sql Server 2005 Express Edition.
whenever i try to create managed objects CLR like stored procedures and stuff from the Sql Server 2005 Enterprise edition it gives me the following error :
"The Sql Server supplied by these connection properties, does not support managed code, please choose a different server"
please help meeeee.. please please, tell me what's the problem ?
I am very new to the subject of writing CLR code inside SQL Server, so I apologise if my questions seem naive.
I have a requirement to populate an asp.net 2.0 GridView control with data columns, some of which are directly from a SQL Server 2005 database, but some of which are calculated by calling CLR methods passing the values from the database columns to those methods.
However, the methods I need to call only make sense in the process context of the client web site which is calling the stored procedure which I want to write to return the data columns.
In effect, I want to be able to make a remote procedure call from within the SQL Server CLR code to the methods available in the client process.
Is this possible? If so, could someone please refer me to an example of how to do it.
If it can be done, it opens up lots of very cool possibilities!
I have inherited a database and with it a set of triggers that are 'apparently' installed. However I have a number of different 'versions' for a specific update trigger and it is not clear from the files which is the latest, hence I am unsure of what 'version' of the trigger is installed in the database itself.
I am trying to retrieve the trigger code from the databse so that i can correctly determine which one of my trigger files is the latest version.
I don't want to end up in a situation where an earlier version of the update trigger is installed as this could wreck the underlying data.
I have tried using the syscomments.text column that relates to the trigger but it only gives me a concatenated version of the sql code and not enough to determine which file version was used for the trigger.
Is there a way of retreiving the entire SQL code that was entered rather than just the first few lines?
I am trying to understand creating SQL Server projects and managed code. So I created a C# SQL Server Database project and named it "CSharpSqlServerProject1" and followed the steps in the following "How to: " from the Help files:
"How to: Create and Run a CLR SQL Server Stored Procedure "
I used the exact code in this "How to: " for creating a SQL Server managed code stored procedure (see below) in C#. However it didn't even compile! When I went to build the code I got the following error message:
"Error 1 Target string size is too small to represent the XML instance CSharpSqlServerProject1"
It does not give a line number or any further information! Since this is a Microsoft example I'm following I figure others must have run into this too. I can't figure out how to fix it!
Here's the code as copied directly from the howto:
using System.Data.SqlClient; using System.Data.SqlTypes; using Microsoft.SqlServer.Server;
public partial class StoredProcedures { [SqlProcedure()] public static void InsertCurrency_CS( SqlString currencyCode, SqlString name) { using (SqlConnection conn = new SqlConnection("context connection=true")) { SqlCommand InsertCurrencyCommand = new SqlCommand();
I need to archive files in a database by checking an archive date for the file contained in a field in a table of a database, if the archive date is greater than todays date then archive the file by moving it to an archive folder. I am thinking the best way might be to use a manged stored procedure, but I also need to run this procedure once every 24 hours at about midnight so how would I do thi? Another way might be by using DTS or something. Has someone else done this and how did they go about it?

I have table T1 and I am trying to extract some date from T1 table based on inserts, updates and deletes. The destination table T2 has three fields F1, F2, F3, so I need something like
Insert into T2 (F1, F2, F3) Select (F1, F2,Type) From T1
Type should be defined based on Insert, Update, or Delete. This will be my first trigger, Can anyone write this trigger for me?
How can I write a trigger for the below issue, I have table named Subscribers with fields Name (varchar), MobileNumber (varchar), status (char). Here if I want to insert a record into this table then first I need to check whether this mobile number exist or not in this table. If it is not exist then this record should be insert and if it is exist then this record should not be insert in to this table.

Hello all I've been thrown in at the deep end by the manager and asked to use a SQL database for a new site. I've managed to get most of the code working but are having trouble with this particular one. The idea is that a user can log a fault (online) and that this gets added to a table. Once the data is added a trigger fires that takes this new data and loops through an "e-mail alert" table containing settings for different department managers and then stores the relevant manager name in a separate table (e-mail sent fromt this table to the manager) once the department and fault id's match. I have the following code (which is by no means good) in my trigger - did I says this is my first outing into SQL land!!ALTER TRIGGER [dbo].[usd_emailalertqueue] ON [dbo].[FaultPostings] AFTER INSERT AS -- declare variables from new fault table DECLARE @iDeptID intDECLARE @iFaultID intDECLARE @iReferenceID int -- declare variables from email alerts tableDECLARE @Managername nvarchar(255)DECLARE @DeptID intDECLARE @FaultID intDECLARE @ReferenceID int -- Read in values new fault tableSELECT @sParam = FaultDescription FROM INSERTEDSELECT @iFaultID = FaultID FROM INSERTEDSELECT @iDeptID = DeptID FROM INSERTEDSELECT @iReferenceID = ReferenceID FROM INSERTED
BEGIN -- Read values from saved e-alertsSELECT @Managername = Managername FROM [dbo].[emailAlerts]SELECT @DeptID = DeptID FROM [dbo].[emailAlerts]SELECT @FaultID = FaultID FROM [dbo].[emailAlerts]
INSERT INTO EmailAlertQueue(ReferenceID,Managername)SELECT @iReferenceID, @Managername FROM [dbo].[emailAlerts] WHERE (@iDeptID = @Deptid) AND (@iFaultID = @Faultid) then END At the moment, this is what happens when a fault is added: the EmailAlertQueue table gets populated with the name of the last managername from the emailAlerts table several times (only if the Dept and Fault id's macth otherwise nothing gets populated.. e.g. if there at 4 alerts setup in the EmailAlerts table with different dept and fault ID's but the last one matches the criteria the emailAlerts table is uotaed with 4 rows containing the managername. (Hope this makes sense). I think I need to have some sort of loop but so far as I can tell a "For Each" loop doesn't work in triggers (i could be wrong though). (I'm not even sure if this is the correct approach to take) As usual, any help is appreciated. Thanks Chooch
Does anyone have code for a trigger that when the user deletes the record trigger it to insert into another table? Thanks in advance and appreciate your help!
Please can anyone help me code the trigger below. I have had errors pointing to "sp_configure 'SQL Mail XPs', 1;" and "RECONFIGURE", that this lines should be not where I have placed them. I have tried other combinations and have not worked at all! Is any other ways I can achieve this all?

CREATE TRIGGER reminder ON Bug_Report FOR INSERT, UPDATE, DELETE AS sp_configure 'SQL Mail XPs', 1; EXEC master..xp_sendmail 'MaryM', 'Don't forget to print a bug report.' RECONFIGURE
I would like to create a script that lists out all of the SQL code for the procedures and triggers I have created in a database.
What I want to do is save the code for each procedure/trigger as a *.SQL file without having to open up each one in Enterprise Manager and save them individually.
Listing the names is easy by looking in sysobjects, but is the SQL code stored in a system table anywhere?
Does anybody have any alternative approach to this problem?
Hi Everyone, I m using ASP.NET 2005 with C# and SQL SERVER 2005. I m using stored procedure and sql datasource control to retrieve the data. I want to use the trigger alongwith storedprocedure. I have created the following trigger on emp_table. CREATE TRIGGER Employeee on emp_tableAFTER DELETE ASDECLARE @empid int SELECT @empid=empid from emp_table where locationid=(SELECT locationid from deleted)IF @@ROWCOUNT=0 DELETE FROM location_table where locationid=(SELECT locationid from deleted)What i wanted to know is how can i use it with asp.net and sql server 2005 when any update,delete or insert query is executed thru the stoed procedure...What code is required to use the trigger with the application of .NET thanxs.....
I have a database trigger that is set to call a CLR trigger/stored proc when a certain field in a table is updated. The issue is that if i execute the stored proc manually in enterprise studio, it works perfectly but the same call made through the trigger does not go through. A few more details -
I have CLR integration enabled on the sql server.
The dbo has UNSAFE ASSEMBLY rights
I have the both the assembly and the serialized dll imported in the database.
Here's the definition of the stored proc -
CREATE PROCEDURE [dbo].[WriteXMLNotification]
@TaskID [nvarchar](20)
WITH EXECUTE AS CALLER
AS
EXTERNAL NAME [DataInterfaceWebServices].[TaskUpdateXMLWriter.WriteXMLNotification].[run]
and the trigger -
CREATE TRIGGER [dbo].[tr_Task_U]
ON [dbo].[_Task]
FOR UPDATE, INSERT AS
IF UPDATE (TaskType_Status) OR UPDATE (TaskType) OR UPDATE (TaskType_SubType1)
BEGIN
SET NOCOUNT ON;
DECLARE @status AS INT
DECLARE @taskType AS INT
DECLARE @taskSubType AS INT
DECLARE @taskID as sysname
DECLARE @cmd as sysname
DECLARE @parentTask as sysname
DECLARE @NotificationXMLTaskID as sysname
SELECT @status = [TaskType_Status] FROM inserted
SELECT @taskType = [TaskType] FROM inserted
SELECT @taskSubType = [TaskType_SubType1] FROM inserted
SELECT @taskID = [TaskID] FROM inserted
SELECT @parentTask = [Parent_TaskID] FROM inserted
SELECT @NotificationXMLTaskID = [MCCTaskID] FROM _TaskNotificationXML WHERE [MCCTaskID] = @parentTask
IF (@status = 2602) AND (@taskType = 2282) AND (@taskSubType = 19500)
BEGIN
exec WriteXMLNotification @taskID;
END
ELSE IF (@taskType = 2285) AND (@parentTask IS NOT NULL) AND (@NotificationXMLTaskID IS NOT NULL)
BEGIN
exec WriteXMLNotification @parentTask;
END
END
I stepped into the trigger and it seems to execute the line " exec WriteXMLNotification @taskID;" but nothing happens, but if I run that same line manually, it works. Could it be that the impersonation by the EXECUTE AS clause is causing it to fail?
My goal is to create a trigger to automatically set the value for a status id on a table based on set criteria. Depending on the values of other fields will determine the value that the status id field is assigned. So far, I have written the trigger to update the status id field and I go through a seperate Update statement for each status id value. The problem is that I can't get this to work at the record level. The problem that I am getting is that if I have 50 records in TABLE1 and at least one of them satisfies the where clause of the update statement, all of the records get updated. So, using these two update statements, all of my records end up with a status value of '24' because that was the last update statement run in the trigger. Here is the code I have so far:
CREATE TRIGGER dbo.JulieTrigger1
ON dbo.Table1
AFTER INSERT,UPDATE
AS
BEGIN
BEGIN TRY
/*Update Table1.Status to POTENTIAL (id 23) status */
UPDATE TABLE1
SET status_id = 23
WHERE EXISTS (SELECT *
FROM TABLE1 a INNER JOIN TABLE2 b
ON b.order_id = a.order_id
WHERE a.start_dt IS NULL
AND b.current_status_ind = 1
AND b.lead_status_id NOT IN (15,16)
AND a.order_id = TABLE1.order_id)
/*Update Table1.Status to ACTIVE (id 24) status */
