Need Help Writing A Trigger
Nov 20, 2003
Please find the necessary SQL scripts to generate a small version of my database and some data at the bottom of this post.
Here's a short description of what the database is all about: It's a project tracking and management system. Contracts go into the tblDeals table. Because each project may be different in nature, project phases are defined in tblPhaseType and tblPhase tables. The table used to keep track of what's going on is the tblProduction table.
Here's what I need to do. When a project is completed -- meaning it has gone through all the phases that it needs to go through -- I want a trigger to fire up and change the contract status in the tblDeals table to "Completed" whose value is 1. When a new contract gets entered into the table, the Contract Status is set to 5 by default which means "In Progress" -- as defined in tblContractStatus. The tricky part is that because, each project is different and has different number of phases, the trigger has to make sure that all the phases have been submitted into the tblProduction table for that particular deal.
I'd really appreciate some help here. Thanks in advance for all your help.
---------------------------------------
Here's the script
---------------------------------------
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[FK_tblDeals_tblCompany]') and OBJECTPROPERTY(id, N'IsForeignKey') = 1)
ALTER TABLE [dbo].[tblDeals] DROP CONSTRAINT FK_tblDeals_tblCompany

Any help appreciated!
Is there any performance enhancements to be gained by storing frequently 'trigger-written-to' databases on a seperate disk to the source database? In particular, we keep a 'history' database of all inserts/updates/deletes against records, activated by triggers, and I was wondering if I would gain performance enhancement by locating the two databases on different disks?
Thanks in advance

Experts: Please assist with coding a trigger for a SQL Server 2005 .NET application.
Here's the scenario:
Suppose there are tables MEMBERS, ACTIVITY, and HEADCOUNT that look like this:
MEMBER
member_id (int)
member_name (varchar(50))
...etc
ACTIVITY
activity_id (int)
activity_name (varchar(50))
...etc
HEADCOUNT
headcount_id (int)
member_id (int)
activity_id (int)
...etc
Suppose also that the ACTIVITY table is already populated with several records, say with activity_id = 1, 2, and 3.
OBJECTIVE: When a new member record is added to MEMBER, say member_id 10, insert one record in the HEADCOUNT table for EACH activity in ACTIVITY for that member. Thus, if member #10 is added to MEMBER, then the trigger (or some other mechanism) would add the following records to HEADCOUNT (which, say, already has 30 records):
headcount_id member_id activity_id
31 10 1
32 10 2
33 10 3
I've been advised that a trigger should do the trick for this, but as I'm totally new to SQL, I'll need some help. I'm guessing some iterating SQL command language might be required, but as I'm new to SQL, I don't know how to proceed.
Note that I'm building an ASP.NET application based on VB, and so records will be added to MEMBER through a tableadapter INSERT command. (Though I suspect this has no bearing on trigger behavior.)
Much obliged for your assistance.

I am developing an application in vb.net 2005 using SQL Server 2000.
In this I have two tables SessionMaster and SessionChild.
Fields of session master - SessionMastId, Start_Date, End_Date, Session_Type,
Fields of session child - SessionChildId, SessionMastId, UserName, Comment.
SessionMastId and SessionChildId are primary keys of respective tables and also they are auto increment fields.
Please how to write trigger to insert record into both tables at a time.

Hey,
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.
Thanks.

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. We'reworking on running a SQL trace but if anybody has any input, fireaway.Thanks!create table x(Id int,Account varchar(25),Info int)GOinsert into x values ( 1, 'Smith', 15);insert into x values ( 2, 'SmithX', 25);/* Update trigger tu_x for table x */create trigger tu_xon xfor updateasbegindeclare @TriggerRowCount intset @TriggerRowCount = @@ROWCOUNTif ( @TriggerRowCount = 0 )returnif ( @TriggerRowCount > 1 )beginraiserror( 'tu_x: @@ROWCOUNT[%d] Trigger does not handle @@ROWCOUNT[color=blue]> 1 !', 17, 127, @TriggerRowCount) with seterror, nowait[/color]returnendupdate xsetAccount = left( i.Account, 24) + 'X',Info = i.Infofrom deleted, inserted iwhere x.Account = left( deleted.Account, 24) + 'X'endupdate x set Account = 'Blair', Info = 999 where Account = 'Smith'

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 following code write audit entries to a Table called
'Audit'
with columns
'ActionType' //varchar
'TableName' //varchar
'PK' //varchar
'FieldName' //varchar
'OldValue' //varchar
'NewValue' //varchar
'ChangeDateTime' //datetime

aRow["ChangedBy"] = User;
AuditTable.Rows.InsertAt(aRow, 0);//Insert the Entry
}
break;
default:
//Do Nothing
break;
}
AuditAdapter.Update(AuditTable);//Write all Audit Entries back to AuditTable
conn.Close(); //Close the Connection
}
}
//Helper function that takes a Table of the Primary Key Column Names and the modified rows Values
//and builds a string of the form "<PKColumn1Name=Value1>,PKColumn2Name=Value2>,......"
public static string PKStringBuilder(DataTable primaryKeysTable, DataRow valuesDataRow)
{
string temp = String.Empty;
foreach (DataRow kColumn in primaryKeysTable.Rows)//for all Primary Keys of the Table that is being changed
{
temp = String.Concat(temp, String.Concat("<", kColumn[0].ToString(), "=", valuesDataRow[kColumn[0].ToString)].ToString(), ">,"));
}
return temp;
}
}
The trick was getting the Table Name and the Primary Key Columns.
I hope this code is found useful.
Comments and Suggestion will be much appreciated.

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)
select i.id
from inserted i
where
--specific USER

I have some experience with MS SQL mostly installation, configuration, maintaining, etc. But I am trying to teach myself some TSQL. I have bought a few beginner books and have some test machines. In advance, I appreciate any feedback!
I have a database with two tables. I want to calc the min salary for a class of employees. The "wage" is in one table and the "status" is in another.
USE Database
GO
SELECT MIN(Wage) AS "Min Salary", Status
FROM Employee, Job
WHERE Status = '1'
GROUP BY Wage, Status
GO
The result set brings back all not the "status" class that I want.
Again, I am relatively new so take it easy on me!
Thanks,
grinch

Hi,
I am new to this programming and SQL.
I am following the: Lesson 8: Obtaining Data from a SQL Server 2005 Express Edition Database video series. I cannot get the following to write changes to the SQL Database:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
BindingSource1.EndEdit()
'CustomerTableAdapter1.Update(MyCompanyDataSet1.Customer)
Dim rowsAffected As Integer = 0
rowsAffected = CustomerTableAdapter1.Update(MyCompanyDataSet1.Customer)
MessageBox.Show(rowsAffected.ToString())
End Sub
End Class
I do get the message box to popup showing 1 row of changes when I make one change, however that change does not get written to the database. Is this enough info to have any idea why?
Thanks

I was hoping that someone might be able to help a SQL statement for this, if possible. I have two tables, InvoiceDetails and InvoiceLineItems. What I'd like to do is write a query that will return all invoices, but also return a value InvoiceTotal Based on SUM(InvoiceLineItems.qty * InvoiceLineItems.unitPrice). I've tried a few different methods of writing this, but haven't had much luck. Can anyone shed some light on this for me? Thanks.

Hi.I realize this may have been asked a thousand times before, but it's still not working for me. I would appreciate any help with it. First, I created a GridView, and from it I created a new SqlDataSource and let it point to the database in C:My ProjectApp_DataASPNETDB.MDF. This automatically created a connectionString in the Web.Config file, saying the following: "R1ASPNETDBConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename="C:My ProjectApp_DataASPNETDB.MDF";Integrated Security=True;Connect Timeout=30;User Instance=True"
providerName="System.Data.SqlClient" /> Now when I try to programatically use that connection string, the program crashes. Below is my code: <script runat="server"> String sqlConnectionString = @"Data Source=.SQLEXPRESS;AttachDbFilename="C:My ProjectApp_DataASPNETDB.MDF";Integrated Security=True;Connect Timeout=30;User Instance=True";
protected void Page_Load(object sender, EventArgs e) { using (SqlConnection conn = new SqlConnection(sqlConnectionString)) { conn.Open(); const String selectQuery = "SELECT StatusName FROM Status ORDER BY StatusName"; Label1.Text = ""; using (SqlCommand cmd = new SqlCommand(selectQuery, conn)) { SqlDataReader dr = cmd.ExecuteReader(); if (dr.Read()) { Label1.Text += dr[0]; while (dr.Read()) { Label1.Text += ", "; Label1.Text += dr[0]; } Label1.Text += ". "; } else
Label1.Text = "None."; } if (conn != null) conn.Close(); } } Here's the error message I'm getting: Server Error in '/My Project' Application.

Is it possible to do the following without cursors or creating an identity column:
I have a table from legacy data with ~ 1 million records. I need to insert this into the new table which has a unique varchar(11) key. For the new system this key is generated by calling a SP that returns the next key in sequence. To put the legacy data records in the same table I want to first create a new column at end of legacy data table and populate this using SQL without going thru using cursor and calling the SP for each and every record to get a unique varchar(11) key.
In short here is what I want:
Field1 Field2 varchar(11)key
------ ------ -----------
jsdhf dsf99 1LEG
878jh whjhj 2LEG
8728jh whjhj 3LEG
8578jh whjhj 4LEG
3878jh whjhj 5LEG
6878jh whjhj 6LEG
8508jh whjhj 7LEG
...
...
...
4878jh whjhj 1000000LEG
How do I generate this key using an SQL stmt?
Thanks in advance,

I need assistance on writing a particular query:
I need to be able to filter out duplicates that have different values in a particular field.
For example, I have a table that contains the following:
Code:
WBS1 WBS2 WBS3 Amount Section
123 13 00 475 F
123 13 00 0 L
123 21 01 125 C
123 24 03 50 L
I need to filter out the first two lines because they have the same values for the first three columns but the last column under 'Section' has different values.
Can someone help me?

Hello I'm new on sql server and I wonder if there's an specific order for writing a query's clauses (joins, and other conditions in where clause or even the order of the tables in the from clause), I mean, I have a query that takes 1 minute executing, but if I execute the same query after moving the tables in the from clause (changing the order) It takes 5 seconds, could you please tell me Why ??? and what's the best order from writing a query ?
This is the query I was talking about:
SELECT TREP_VALOR_PRECIOS.CDPRECIO,
TREP_VALOR_PRECIOS.NMANO,
TREP_VALOR_PRECIOS.NMSEMANA,

Hi Friends,
I need help on writing an optimized query for the following problem..
Consider a table with columns "Date Emp1 Emp2"
Date Emp1 Emp2
1-feb 1 . . 2
2-feb 3 . . 4
3-feb 6 . . 1
4-feb 1 . . 2
5-feb 1 . . 5
6-Feb 5 . . 7
Now, I want search for records with employee id 1 in a way that if column emp1 contains 1 then I want the data in column emp2, and if column emp2 contains 1, then I want data in column emp1.
The output has to be a single column with no duplicate values. In the above example, for employee id 1, the output would be, 2,5 and 6 only.
This table has lakhs of records. I have to scan both columns for a given employee id. What will be the most optimized way to retrieve the data faster. Also, do I need to restructure this table for faster data retrieval?
I have indexes on emp1 and emp2 columns. Do we need union here and if yes, what is the best optimized query for the same?

Help! I need to write a query that looks at one table with two columns. One column has 20K records and the second column has 25K records. I need to compare the two columns and pull out the difference between the two columns. The majority of the two columns data is the same but there are some that do not have a match between the two. The data is not in any current order. HELP! THANKS!
