Am using SQL Server 2000 on WINXP Pro. Have a requirement to change some
Oracle triggers to SQL 2000. I have modied this one Insert Trigger, but get
an error when I attempt to compile:
CREATE TRIGGER trg_ins_attend_audit_log

phone,lic_year,print_lic,lic_exp,send_hx,
user_id,getdate(),"I",modified
from inserted
END
ERROR:Incorrect syntax near "AS."
Can anyone point out the error of my ways here??
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?

Hi there, 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 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?
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?
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 */
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
Hi all--I'm trying to convert a function which I inherited from a SQL Server 2000 DTS package to something usable in an SSIS package in SQL Server 2005. Given the original code here: Function Main() on error resume next dim cn, i, rs, sSQL Set cn = CreateObject("ADODB.Connection") cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>" set rs = CreateObject("ADODB.Recordset") set rs = DTSGlobalVariables("SQLstring").value
for i = 1 to rs.RecordCount sSQL = rs.Fields(0).value cn.Execute sSQL, , 128 'adExecuteNoRecords option for faster execution rs.MoveNext Next
Main = DTSTaskExecResult_Success
End Function
This code was originally programmed in the SQL Server ActiveX Task type in a DTS package designed to take an open-ended number of SQL statements generated by another task as input, then execute each SQL statement sequentially. Upon this code's success, move on to the next step. (Of course, there was no additional documentation with this code. :-)
Based on other postings, I attempted to push this code into a Visual Studio BI 2005 Script Task with the following change:
public Sub Main()
...
Dts.TaskResult = Dts.Results.Success
End Class
I get the following error when I attempt to compile this:
Error 30209: Option Strict On requires all variable declarations to have an 'As' clause.
I am new to Visual Basic, so I'm on a learning curve here. From what I know of this script: - The variables here violate the new Option Strict On requirement in VS 2005 to declare what type of object your variable is supposed to use.
- I need to explicitly declare each object, unless I turn off the Option Strict On (which didn't seem recommended, based on what I read).
Given this statement:
dim cn, i, rs, sSQL
I'm looking at "i" as type Integer; rs and sSQL are open-ended arrays, but can't quite figure out how to read the code here:
This code seems to create an instance of a COM component, then pass provider information and create the recordset being passed in by the previous task, but am not sure whether this syntax is correct for VS 2005 or what data type declaration to make here. Any ideas/help on how to rewrite this code would be greatly appreciated!
Table 1: AddressBook Fields --> User Name, Address, CountryCode
Table 2: Country Fields --> Country Code, Country Name
Step 1 : I have created a Cube with these two tables using SSAS.
Step 2 : I have created a report in SSRS showing Address list.
The Column in the report are User Name, Address, Country Name
But I have no idea, how to convert this Country Code to Country name.
I am generating the report using the Layout tab. ( Data | Layout | Preview ) Report1.rdl [Design]
Anyone help me to solve this issue. Because, in our project most of the transaction tables have Code and Code description in master table. I need to convert all code into corresponding description in all my reports.
Hello, I'm using ASP.Net to update a table which include a lot of fields may be around 30 fields, I used stored procedure to update these fields. Unfortunatily I had to use a FormView to handle some TextBoxes and RadioButtonLists which are about 30 web controls.

Thank you
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.
Are there any limitations or gotchas to updating the same table whichfired a trigger from within the trigger?Some example code below. Hmmm.... This example seems to be workingfine so it must be something with my specific schema/code.

This Audit Trigger is Generic (i.e. non-"Table Specific") attach it to any tabel and it should work. Be sure and create the 'Audit' table first though.

The trick was getting the Table Name and the Primary Key Columns. I hope this code is found useful.
Hi,I need some help here. I have a SELECT sql statement that will query the table. How do I get the return value from the sql statement to be assigned to a label. Any article talk about this? Thanks geniuses.
I want to be able to create a trigger that updates table 2 when a row is inserted into table 1. However I€™m not sure how to increment the ID in table 2 or to update only the row that has been inserted.
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)
When a row gets modified and it invokes a trigger, we would like to beable to update the row that was modified inside the trigger. This is(basically) how we are doing it now:CREATE TRIGGER trTBL ON TBLFOR UPDATE, INSERT, DELETEasupdate TBLset fld = 'value'from inserted, TBLwhere inserted.id= TBL.id....This work fine but it seems like it could be optimized. Clearly we arehaving to scan the entire table again to update the row. But shouldn'tthe trigger already know which row invoked it. Do we have to scan thetable again for this row or is their some syntax that allows us toupdate the row that invoked the trigger. If not, why. It seems likethis would be a fairly common task. Thanks.
Salve, non riesco a disabilitare un trigger su sqlserver nè da queryanalyzer, nè da enterprise manager.In pratica tal cosa riuscivo a farla in Oracle con TOAD, mentre qui nonriesco.Mi interessa disattivarlo senza cancellarlo per poi riattivarlo al bisognosenza rilanciare lo script di creazione.Grazie a tuttiHi I need to disable a DB trigger and I'm not able to do this neither withquery analyzer, neither with enterprise manager.I remeber this job was quite simple using TOAd in Oracle.I'm interested in making it disabled not delete it, without run creationscript.Thanks a lot to everybody.
Hi, 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?
