I'm using DataAdapter.Update() to update data in a table. My question is; how do I create a trigger that works after the update has completely finished?
For example if my update adds 50 new rows to a table the trigger I've currently got fires after each new row that is added ie 50 times in total. Is it possible to get it to trigger after the last (ie 50th) row is added???
Hi, I have a table with somefields, here i will only mention on which i need to perform an action, possibly with the use of Trigger.
Fields = Active, inactiveDate Active Field is of bit datatype mean conatins 1 or 0, 1 means the user is active, but when i change the active field to 0, and make the user inactive i want the date to be populated automatically to inactiveDate field when active field is changed to 0.
I have one table named as "Order", and other table as "Shipment". Now, I want to check if one column name "Status" in the "Ă–rder" table has been changed (when it becomes status = 7) then I need to insert records in "Shipment" table.
Order Table: OID===Order_Product===Order_Description===Order_Status
But it inserts the records into Shipment Table every time the status field or any other field in the Order Table is changed. What I want is that, "When Status Column in Order Table is Updated to 7, then insert record in Shipment Table".
Hi, I am populating a datagrid with data from one sql table, I add additional columns and then wish to write it back out to another table. I have written the following code to acheive this, however it keeps throwing the follwing exception - "Update requites a valid UpdateComman when passed a DataRow collection with modified rows" I've looked and I can see what the problem is, can anybody help please? Private Sub FillData() 'SQL connection Me.sqlconnection = New System.Data.SqlClient.SqlConnection Me.sqlconnection.ConnectionString = ConfigurationSettings.AppSettings("CuroConnection")
Dim sql As String If Request("action") = "gen" Then sql = "select item from tblPickList where GroupName = 'xxx'AND Category = '" & Category2 & "' ORDER BY item ASC" ElseIf Request("action") = "fav" Then sql = "select identifiertext as item from tblfavourites where HRID = " & Session("hrid") & " and type = 3 ORDER BY identifiertext ASC" ElseIf Request("action") = "spec" Then sql = "select item from tblPickList where GroupName = '" & GroupID & "' AND Category = '" & Category2 & "' ORDER BY item ASC" End If
ds = New DataSet da = New SqlClient.SqlDataAdapter(sql, sqlconnection)
Try sqlconnection.Open() da.Fill(ds, "tblPickListTemp") sqlconnection.Close() Catch ex As Exception sqlconnection.Close() End Try
ds.Tables(0).Columns.Add("HRID") ds.Tables(0).Columns.Add("Flag") 'may possibly add a favourites column here at a later date to ensure no duplication
Dim dr As DataRow For Each dr In ds.Tables("tblPickListTemp").Rows dr("HRID") = Session("hrid") dr("Flag") = 0 Next
DgrdFavourites.DataSource = ds DgrdFavourites.DataBind() End Sub
Public Sub CreateTempRecords()
'SQL connection Me.sqlconnection = New System.Data.SqlClient.SqlConnection Me.sqlcommand = New System.Data.SqlClient.SqlCommand Me.da = New SqlClient.SqlDataAdapter Me.sqlconnection.ConnectionString = ConfigurationSettings.AppSettings("CuroConnection")
Dim sql As String sql = "Insert into tblPickListTemp (Item, HRID, Flag) values (@Item, @HRID, @Flag)" sqlcommand.CommandText = sql sqlcommand.Connection = sqlconnection
sqlcommand.Parameters.Add("@Item", "Item") sqlcommand.Parameters.Add("@HRID", "HRID") sqlcommand.Parameters.Add("@Flag", "Flag") da.InsertCommand = sqlcommand da.Update(ds.Tables(0)) End Sub
this does not work, it does work however if i replace the Me.textboxhello.Text with a value in quotation marks or with another text box not linked to that feild in the table... it does not work with the relevant text box!!!!!!!!
Hy, again! I am at the begining of an application. I have some modules that insert, delete and update only one row at one table. My question is should I use dataadapter.Update() or ExecuteNonQuery(). I prefer ExecuteNonQuery because I want to build a class : DataLayer to implement my own InsertProcedure(), UpdateProcedure(),DeleteProcedure(). I want speed in my application, so which is the best: dataadapter.Update() OR ExecuteNonQuery(). Thank you!
Hi - I know my way around VS but I am just exploring "advanced" SQL Server 2005 and have run into a challenge which I think a trigger could solve, but I am not sure and also don't know how to set that up. So any help or links to tutorials are highly appreciated. Here is the challenge: I have a table with a number of fields, among them RequestID (bigint) and Booktime (datetime). What I would like to happen is whenever someone writes a value different from NULL into RequestID, Booktime gets set to the current timestamp. When RequestID gets set to NULL, Booktime gets set to NULL. Is there a way to do this with a trigger (or an otherwise elegant way)? Thanks in advance for ANY help or ideas. Oliver

hi,CAn i have one trigger for both Update and DeleteDelete Trigger---------------------create Trigger [tr_delete_user_log]on [dbo].[user_log] for deleteasbegininsert into z_user_log select * from deletedendTrigger Update---------------------CREATE Trigger [tr_update_user_log]on [dbo].[user_log] for updateasbegininsert into z_user_log select * from deletedendCan i have one trigger instead of these Triggers ..
I am having trouble getting an Update call to actually update records. The select statement is a stored procedure which is uses inner joins to link to property tables. The update, insert, and delete commands were generated by Visual Studio and only affect the primary table. So, to provide a simple example, I have a customer table with UID, Name, and LanguageID and a seperate table with LanguageID and LanguageDescription. The stored procedure can be used to populate a datagrid with all results (this works). The stored procedure also populates an edit page with one UID (this works). After the edit is completed, I attempt to update the dataset, which only has one row at this time, which shows that it has been modified. The Update modifies 0 rows and raises no exceptions. Is this because the update, insert, and delete statements do not match up one-to-one with the dataset? If so, what are my choices?
I am trying to insert data into 2 different tables. I am using dataadapter and dataset.
Protected Sub SubmitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitButton.Click Call ConnectionString()
Dim insertSQL As New SqlCommand() insertSQL.Connection = sqlConn insertSQL.CommandText = "SELECT location.CountryName, location.CityName, location.BuildingName, location.FloorID, rooms.name, rooms.FloorID AS Expr1 FROM location INNER JOIN floors ON location.FloorID = floors.id INNER JOIN rooms ON floors.id = rooms.FloorID"
Dim ds As New DataSet() Dim da As New SqlDataAdapter()
da.SelectCommand = insertSQL Dim scb As New SqlCommandBuilder(da)
Try da.Fill(ds) Dim ndr = ds.Tables("location").NewRow Dim ndr2 = ds.Tables("rooms").NewRow
My DataAdapter.Update() Method is running this query against my database and all the parameters and the formatting looks correct to me. I was wondering if anyone could identify obvious errors.... Thanks!
I have never used triggers before and I have tried to solve one problem. If I have the column "currency" in a table and want to make sure that the entered value i valid in relation to another table that contains valid currency formats, I did it like this:
--------------------------------- CREATE TRIGGER [trigger_checkCurrency] ON [dbo].[Client] FOR INSERT, UPDATE AS declare @currency as char(50) declare @country as char(50)
declare cur cursor for SELECT currency, country FROMinserted
OPEN cur fetch cur into @currency, @country WHILE @@FETCH_STATUS = 0 BEGIN if not exists(select * from listinfoid where listname = 'currency' and listid = @currency) begin set @currency = (cast(@currency as varchar (3)) + ' is not a valid currency') CLOSE cur DEALLOCATE cur RAISERROR (@currency,16,-1) with log return end if not exists(select * from listinfoid where listname = 'country' and listid = @country) begin set @country = (cast(@country as varchar (3)) + ' is not a valid contry') CLOSE cur DEALLOCATE cur RAISERROR (@country,16,-1) with log return end else fetch cur into @currency, @country
END CLOSE cur DEALLOCATE cur update Client set currency = UPPER(currency), country = UPPER(country) ---------------------------------
I use a cursor to handle multiple rows in an update query. (SQL2000-server)
Is there an easier och better way to do this? I´m a bit unsure of this code.
Hi everyoneI am trying to create a DELETE Trigger. I have 2 tables. Table1 andTable2. Table 2 has all the same fields and records as Table1 + 1extra column "date_removed"I would like that when a record is deleted from Table 1, the triggerfinds that record in Table2 and updates the date_removed filed withcurrent time stamp.The primary key on both is combination of domain,admin_group and cn.CREATE TRIGGER [tr_updateTable2] ON [dbo].tbl_Table1FOR DELETEASUpdate Table2SET date_removed = getDate()I'm stuck here, how do I manipulate on Table2 only the records thatwere deleted on Table1, so to only update date_removed filed for themin Table2?I guess i need to compare domain, cn and admin_group, but I don't knowhow.Any help would be greatly appreciatedThanks! :-)
how to do this i have table of employee ,evry employee have a unique ID "empid" empid VAL_OK -------------------------- 111 0 222 0 333 0

Are there any limitations or gotchas to updating the same table whichfired a trigger from within the trigger?Some example code below. Hmmm....

I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.  Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?
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,
I want to update two tables in one page. So I created two FormView bound on two SqlDataSource controls, and I create a Update button on the bottom of page. And I writen some codes as below: btnUpate_Click(object sender, EventArgs e){ sqlDataSource1.Update(); sqlDateSource2.Update();} But, the records haven't updated. In SqlDataSource2_Updating() function, I found all the parameters is null. So, how to modify my code to do it.
I have an update trigger which fires from a transactiion table to update a parent record in another table. I am getting no errors, but also no update. Any help appreciated (see script below)
create trigger tr_cmsUpdt_meds on dbo.medisp for UPDATE as
if update(pstat) begin update med set REC_FLAG = 2 from deleted dt where med.uniq_id = dt.uniq_id and dt.pstat = 2 and dt.spec_flag = 'kop' end
I am trying to update a fields with an UPDATE statement but I keep getting the error message when I run the query.
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
I have this Update trigger that I know is causing the error message because I guess it's not built to manage multi-row updates.
Can someone help me re-write it. I also tried using the WHERE p.ID = p.ID but when I do that it modifies all rows in the modifieddate column instead of just the cells/rows that I'm updating
ALTER TRIGGER [dbo].[MultitrigCA] ON [dbo].[ProdDesc] AFTER UPDATE AS
SET NOCOUNT ON
IF UPDATE (codeabbreviation) UPDATE p sET p.ModifiedDate = GETDATE() FROM ProdDesc AS p WHERE p.ID = (SELECT ID FROM inserted)

i have a database with about 20 tables. i appended to each table a column "UpdatedOn", and i want to write a trigger to set the date of the update date in that column, using a trigger.
i want to avoid the trigger launching for the last column (UpdatedOn).
how can i detect the rows that changed, and modify only the update date/time? i read something about TableName_Inserted and TableName_Deleted, but i would prefer to copy as generic as possible the data from there, meaning, not to write column names in my script.
another idea i thought about was to prevent the trigger executing if no other column except for UpdatedOn changed, but... i encounter some trouble, when i try to pass column name (as string) to UPDATE() function.(Error: Expecting ID or QUOTED_ID)
I have a table that has a number of data fields,I need to be able to capture datatime when the date field was entered or entered value changed.I was told I need to create a trigger on that table that contains all the fields.
I have seen the syntax for creating triggers, and read some documentation but I am still in the dark as how to create what I need to.
I was hoping to see if somebody had a similar example or an advice, anything is more than what I have at the moment.

Since we have given Null to ''Workphone'',''Cellphone '', ''Email ID''.when inserting the data into these table.if the particular columns are empty while inserting also the data will get populate into the table.And.I need is if these columns are ''Workphone'',''Cellphone'' , ''Email ID'' they cant insert the data into table.
Like it must trigger like ''Please enter atleast one of these ''Workphone'',''Cellphone'' , ''Email ID'' columns.
