Trigger To Update One Record On Update Of All The Tables Of Database
Jan 3, 2005
hi!
I have a big problem. If anyone can help.
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?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.

Hi guys, may I know is it possible to create an update trigger like this ? Assuming there are two database, database A and database B and both are having same tables called 'Payments' table. I would like to update the Payments records on database A automatically after Payments records on database B had been updated. I can't use replication because both tables might having different records and some records are the same. Hope can get any assistance here, thank you.
Best Regards,
Hans

Hello All,I have 2 tables in a MS SQL DB. Table1 and Table2.LogTable2.Log was a copy of Table1 + an extra column for date_deleted. Ihave 2 Triggers on Table1, Insert and delete. So when a record isinserted into Table1 it's copied onto Table2.log, and when deleted inTable1 the same record in Table2.log is time stamped with time ofdeletion.I would like to have another Trigger on Table1 for update. So if acertain field (not primary key) is updated for a record it is alsoupdated in Table2.log This way Table2.log will always have exactly thesame fields per record as Table1.I'm not sure how to reference the modified records only and updatejust the modified fields...something like...?----------------------------CREATE TRIGGER [tr_updateT_Log] ON [dbo].Table1FOR UPDATEASUpdate Table2.LogSET description = , office =-------------------------------------------------Any help would be greatly appreciatedThanksY

Am in a small fix. my Trigger is updating my entire table records , i don't want that, i want to update a column in the record that is updated by my application using a trigger that tracks updates on that table.
Is there a way i can track the updated record on my table and then update a field in that record through my TRIGGER?
My database is MSSQLServer2005 Enterprise Edition..
Below is my code
CREATE TRIGGER [TR_Employee]
ON [Test_1_1].[dbo].[Employee]
For UPDATE
Not For Replication
AS
BEGIN
Update Employee set Last_Changed = (select getDate())
END
Go

I am new to SQL and these forums, so please bear with me :)
My basic question is if I can create a update trigger that will pull info from another record in the same table if data in certain fields match the existing record.
An example:
The user creates a new record. If said user enters data in specified fields that matches data in the same fields in another record in the same table, can a update trigger be used to fill out the rest of this record with the data from the record that matches?
If you need more Info on my problem, ask and I will try to explain better. There may be a better way of doing this than using a trigger, but I am not sure. The fields that I would use to match the data would not be the primary key fields.
Thanks!

I've gotten conflicting info about this in the past so I thought I'd try to get clarification.
When a record is deleted, I'm sure it fires the delete trigger. Does it also fire the update trigger?
Thanks

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Â
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?

Hello,
I was stuck when update database using SqlDataAdapter. I have several textboxes in my webform1. When wepform1 is loaded, they will display user's information. The user can only input content in two textboxes. When user clicks the update button, I hope to update this record in SQL Server 2000 database. However, the program didn't work. There was no error message reported but when I stepped into the code, I found out that dataadapter's update method didn't succeed. I got 0 rows affected. Can I get some advice from someone ?
Here is the code:
string StrUpdateCmd = "Update Table1 Set Hphone = @Hphone, Cphone = @Cphone, Team = @Team Where emailname =@emailname ";
SqlDataAdapter UpdateDa = new SqlDataAdapter("Select * from Table1",SqlConnection1);
UpdateDa.UpdateCommand = new SqlCommand(StrUpdateCmd, SqlConnection1);
//Add parameters of update command.
SqlParameter prm1 = UpdateDa.UpdateCommand.Parameters.Add("@Hphone",SqlDbType.NVarChar, 16);
prm1.Value = txtHphone.Text ;
SqlParameter prm2 = UpdateDa.UpdateCommand.Parameters.Add("@Cphone",SqlDbType.NVarChar, 16);
prm2.Value = txtCphone.Text ;
SqlParameter prm3 = UpdateDa.UpdateCommand.Parameters.Add("@Team",SqlDbType.NVarChar, 16);
prm3.Value = this.DropDownList1.SelectedItem.Value ;
SqlParameter prm4 = UpdateDa.UpdateCommand.Parameters.Add("@emailname",SqlDbType.NVarChar, 50);
prm4.Value = txtEmail.Text;
try
{
DataSet dataset2 = new DataSet();
//Open database connection.
SqlConnection1.Open();
dataset2.Clear();
UpdateDa.Fill(dataset2, "Table1");
this.DataGrid1.DataSource = dataset2.Tables[0] ;
DataGrid1.DataBind ();
//Update database
int ret =UpdateDa.Update(dataset2,"Table1");
if( ret == 1 )
{
ShowMessage("Update succeed!");
}
else
{
ShowMessage("There is an error in updating ");
}
UpdateDa.Fill(dataset2);
//Show data after update.
this.DataGrid1.DataSource = dataset2;
DataGrid1.DataBind ();
}
catch (Exception ex)
{
throw ex;
}
finally
{
sqlConnection1.Close();

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)

hi!
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)
thank you in advance.

I'm very surprised since I cannot do a simple update operation...
Seems that the cursor after a Read, Readfirst, ReadLast or ReadPrevious is gone...
Here is a possible sequence from the user's standpoint.
1) Performs a QBE search
cmd_Logbook_search = Conn_User.CreateCommand()
cmd_Logbook_search.CommandText = sql_Logbook
rset_Logbook = cmd_Logbook_search.ExecuteResultSet(ResultSetOptions.Updatable Or ResultSetOptions.Scrollable)
-----
If rset_Logbook.HasRows = False Then Exit Sub
rset_Logbook.ReadFirst()
Me.Fill_Logbook_TextBoxes()
2) Navigates
Try
If True = rset_Logbook.Read() Then
Me.Fill_Logbook_Textboxes()
Else
rset_Logbook.ReadLast()
Me.Fill_Logbook_Textboxes()
End If
Catch ex As Exception ' esta excepción se levanta si el recordset está vacio
MessageBox.Show(m11, m1, MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1)
End Try
3) Update the record
If Result = DialogResult.Yes Then
Try
rset_Logbook.SetValue(rset_Logbook.GetOrdinal("Altitude"), Me.TextBox_Altitude.Text)
rset_Logbook.Update()
MessageBox.Show("OK", m1, MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1)
Catch ex As Exception
MessageBox.Show(ex.message, m1, MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1)
End Try
End If
And I always gets a "No data exist for row/colum" so...where did the cursor gone?
Any help, please I need to move forward! Thanks a lot in advance!!

Hi
I am new to visual studio and I am attempting to edit records held in mysql, the code below runs and throws no errors "strAdd" is underlined and says that it is used before it has been given a value! But If I debug.print(strAdd) I get the expected string returned. What do I need to do to get the updated records saved?
' code
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim StrAdd as string
cn = New ADODB.Connection
cn.ConnectionString = "Provider=SQLNCLI;" _
& "Server=(local);" _
& "Database=customerlink;" _
& "Integrated Security=SSPI;" _
& "DataTypeCompatibility=80;" _
& "MARS Connection=True;"
Dim mySQL As String
mySQL = "SELECT *" & _
" FROM tblvsol" & _
" Where RevStatus = " & 0 & _
" And GeoCodeStatus = " & 1
cn.Open()
rs = New ADODB.Recordset
With rs
.ActiveConnection = cn
.CursorLocation = ADODB.CursorLocationEnum.adUseClient
.CursorType = ADODB.CursorTypeEnum.adOpenDynamic
.LockType = ADODB.LockTypeEnum.adLockBatchOptimistic
.Open(mySQL)
End With
Do While Not rs.EOF
Code here finds the value for the string variable €˜atrAdd€™
strAdd = New Value
If Not strAdd Is Nothing Then
rs.Fields("location").Value = strAdd
rs.Fields("RevStatus").Value = 1
rs.Update()
else
end if
loop
Regards
Joe
