How WCF Can Get New Inserted SQL Data ?
Oct 25, 2007
dear all,
I have a WCF service which is host in a console application for the time beeing.
This service provide methods for retriving history data when request.
So far so good.
My WCF service need also to know when a particular table (ALARMS tabel ) gets updated with DELETE, INSERT, OR UPDATE. This because my client application (WinForm) need to refresh a datagrid binding to that ALARMS table.
In other words my WCF servcie would send a callback event to my client when it as been notice for a change..
But my problem is how my WCF service can be notify from an update in my SQL table ?
I have tried SQLDependency class, but I give up was not working properly...and hard to know the xact context you are runing on.
Was thinking also of having a timer whcih pool every 1s by calling my tabel store procedure and verifiy is somerow ha changed....
What to do, how to do, what is the best way and thred safe method
Thnaks for help and advise
regards
serge

I have a table with 3 columns: ID, Status, DateTime.
I created a stored procedure to insert a staus value for each ID. This will run every hour. The DateTime stores the time, date when the Status was inserted.
If the procedure was to be run a second time in hour window I do not want any Status to be inserted.
Note: that I cannot rely on the procedure being run at exactly the right time - if it was scheduled to run on the hour (i.e at 1:00, 2:00, 3 :00 etc) but didn't run until 1:20 it sould still be able to run at 2:00.
Does anyone know if there is anyway I can gaurd against this?

Hi,I am using web matrix, and I am trying to insert a data into a MSDE database. I have used webmatrix to generate the update code, and it is executed when a button is pressed on the web page. but when the code is executed I get the error:Syntax error converting the varchar value 'txtAmountSold.text' to a column of data type int.So I added the following code to try to convert the data, but i am still getting the same error, with txtAmountSold.text replaced with "test"dim test as integer

I have a transactional publication done between two databases on different Virtual machines connected with a network. I noticed that for some reason Every time replication is happening (which is every 2,5 seconds) my data is deleted on the target DB (subscriber) then re inserted.
this should not happen, old data should remain then only the new data should be inserted.

I would like to know how data is inserted and selected from table internally. Like how buffers are created and how they are executed.
Eg. Table1Â
col1 col2 col3
1 a 1
2 b 2
I want to know how this data is inserted into tables. How many buffers are created ? Does it depends on the columns? How buffers are executed?Â

We are having xml data in a column. Is it possible to write a trigger to generate a mail if particular kind of data get inserted in a tag.
For ex:
<File AF="910" PTO="ATN_P76035_PSQO" NNO="54545465" KTNNN="AX2" KL="" AD="99" PrqnT="AX2" Stab="21545" KE="45454" TE="65465" Rsaa="BBBB" AK="54544.AX2.POEAX2.546546546.NONTP.NONTP" AK2="">
In the above xml data if we have the value 21545 in Stab tag the trigger needs to be executed and mail needs to be sent to a distribution list.

Hi folks,
Table:
a int,
b int,
c int,
d text
I need to change my AFTER - Trigger from this (example!):
select * into #ins from inserted
to something like
select *(without Text / nText / image -columns) into #ins from inserted.
So I tried to build a string like this: (using INFORMATIONSCHEMES)
select @sql = 'select a,b,c into #ins from inserted'
exec(@sql)
a,b,c are not of Text, nText or Image datatype.
After executing the trigger, I get an error, that inserted is unknown.
Does anyone know how to solve this ?
Thx.

Within a trigger, I'm trying to create a unique table name (using the NEWID()) which I can store the data that is found in the inserted and deleted tables.
Declare @NewID varchar(50) = Replace(convert(Varchar(50),NEWID()),'-','')
Declare @SQLStr varchar(8000)
Set @SQLStr= 'Select * into [TMPIns' + @newID + '] from inserted'
Exec (@SQLStr)
I get the following error: Invalid object name 'inserted'
I know I can do:
Select * into #inserted from inserted
Set @SQLStr= 'Select * into [TMPIns' + @newID + '] from #inserted'
Exec (@SQLStr)
But I don't want to use TempDB as these tables can become big and I also feel that it is redundant. Is there a way to avoid the creation of #inserted?

I'm doing a data migration job from our old to our new database. The idea is that we don't want to clutter our new tables with the id's of the old tables, so we are not going to add a column "old_system_id" in each and every table that needs to be migrated.
I have created a number of tables in a separate schema "dm" (for Data Migration) that will store the link between the old database table and the new database table. Suppose that the id of a migrated record in the old database is 'XRP002-89' and during the insert into the new table the IDENTITY column id gets the value 1, the link table will hold : old_d = 'XRP002-89', new_id = 1, and so on.
I knew I can get the value of IDENTITY columns with the OUTPUT INTO clause, although I have never actually used it. And now I can't get it to do what I need.
Below is some code to set up three tables: the old table, the new one, and the table that will hold the link between the id's of records in the old database table and the new database table.
Code:
CREATE TABLE DaOldTable(
pkCHAR(10)NOT NULL,
a_columnCHAR(10)
)
CREATE TABLE DaNewTable(
idINTNOT NULL IDENTITY,
[Code] ....
Below I tried to use the OUTPUT INSERTED INTO clause. Beside getting the generated IDENTITY value, I also need to capture the value of the old id that will not be migrated to the new table. When I use "OUTPUT DaOldTable.pk" the system gives me the error: "The multi-part identifier "DaOldTable.pk" could not be bound." Using INSERTED .id gives no problem.
Code:
INSERT INTO DaNewTable(a_column)
--OUTPUT DaOldTable.pk, INSERTED.id link_old2new_DaTable--(DaOld_id, DaNew_id)
SELECT a_column
FROM DaOldTable
[Code] ...
--but getting "The multi-part identifier "DaOldTable.pk" could not be bound."
DROP TABLE DaOldTable
DROP TABLE DaNewTable
DROP TABLE link_old2new_DaTable
How can I populate a table that must hold the link between the id's of records in the old database table and the new database table? The records are migrated with set-based inserts.

I have a program to insert rows into a SQL Server table from an ASCII file. There appears to be some data mapping going on. For example:
"J & J Smith" is imported as "J _J Smith".
This doesn't happen on all servers. I can run it against my database and get the desired results.
I looked into the Server Configuation. Under the Security tab there are Mapping options. It appears that you can map _ to something else, but I don't see where you can map & to anything.

I have a dataset that uses generated stored procedures to do its select, insert, update, delete. I am inserting a row to that dataset, and after the update, using the ID of newly created row. This worked just fine until I added triggers to some of the tables on my DB, and now, when I insert a row, the row's ID is not available after the update (it's 0) Any idea what happened / what I have to do to fix this?

I'm creating a web application that has user input on 3 seperate pages. Each page prompts the user for specific information and at the bottom of the page the user will click on the "Submit" button to post the info from the form to the database table.
Once the user has submitted the first page of information how do I retrieve the ID from the CustID column of that row so I can use the Update function to add additional info to that row when the user clicks on the submit button on page 2 & 3. I don't want to hold all the information in variables until the end in case they bail out of the form.

I've seen a lot of info on how to do this with @@IDENTITY and SCOPE_IDENTITY(), but can't get this to work in my situation.
I am inserting a record into a table. The first field is a GUID (UNIQUEIDENTIFIER) that uses newid() to generate a unique GUID. Since I am not using an int, I can't set the IsIdentity property of the field. Without IsIdentity set, @@IDENTITY and SCOPE_IDENTITY() do not work.
How can I get the ID (or whole record) of the last record that I inserted into a SQL database? Note that I am doing this in C#.
As a last resort, I could generatate the GUID myself before the insert, but I can't find C# code on how to to this.
