Question About Querying Xml Returned By Eventdata() Function In Ddl Trigger
Aug 22, 2006
Hi All,
I wanted to query the xml returned by the eventdata() function in a ddl
trigger to view it in result set.
I made that code but it returned null, any help please?
create trigger DatabaseEvents
on database
for
ddl_database_level_events
as
--select
eventdata().value('(/EVENT_INSTANCE/EventType/text())[1]','nvarchar(max)')
declare @data xml
select @data = eventdata()
select
Col.value('(/EventType/text())[1]','nvarchar(max)') as 'Event Type'
,Col.value('(/PostTime/text())[1]','datetime') as 'Post
Time'
from
@data.nodes('/EVENT_INSTANCE')
as EventsTable(Col)
go
Thank you in advance,
Bishoy

The error below is encounter when a mass update is attempted on our employee table.

I have a procedure that calls a SVF to convert an xmldocument. The ultimate purpose is to update the xml in a column in a multi-million row table. The xml is stored as varchar(MAX), it was supposed to carry any type of text, initially at least.
My question is: why is the xml-parsing performed inside the function much slower when i pass the xmldocument as type xml than when it is passed as varchar(MAX) and the CAST to xml is within the function? Does processing the xml input parameter in SlowFunction involve expensive crossing of some context border?
The two versions of the SVF (they return the rowcount in this simplified example):
CREATE FUNCTION [dbo].[FastFunction]
(
@inDetaljerText varchar(MAX)
)
RETURNS int
[Code] ....
The two versions of the SP
CREATE PROCEDURE [dbo].[FastProcedure]
AS
BEGIN
SET NOCOUNT ON;
select
dbo.FastFunction(al.Detaljer)
[Code] ....

Is there a way to set what value is returned via app_name function?
I have a SQL Server 2005 database that is written to by a MS Access front end... but I have users who have written their own access front ends that are manipulating data incorrectly. I want to allow the approved access applications but disallow the user written ones.
Application roles are not an option because there is also a propietary software package that writes to the databases that we would not be able to modify to work with application roles. Allowing a whitelist of named applications is my only way to pull this off.
How can I make MY access application report nameX instead of Microsoft Access or other similar generic name?

Please try the following, see that trigger is getting invoked, even if there is no row inserted into trigger table.
drop TABLE X

GO
drop TABLE Y
CREATE TABLE Y (
y1 bigint NOT NULL ,

Hi, have configured an ODBC linked server for an Adaptive Server Anywhere (ASA6.0) database.
I have to write a function (not a procedure) that receives a number (@Code) and returns 1 if it was found on a table in the linked server, or 0 if not. Looks very simple...
One problem, is that the queries on a linked-server must be made through the OPENQUERY statement, which doesen't support dynamic parameters. I've solved this making the whole query a string, and executing it, something like this:
SET @SQL='SELECT * FROM OPENQUERY(CAT_ASA, ''SELECT code FROM countries WHERE code=' + @Code + ''')'
EXEC sp_executesql @SQL
(CAT_ASA is the linked-server's name)
Then, i would use @@ROWCOUNT to determine if the code exists or not. But before this, a problem appears: sp_executesql is not allowed within a function (only extended procedures are allowed).
Does somebody know how to make what i want?? I prefer to avoid using temporary tables.
Thanks!

Here is the scenario,
I have 2 stored procedures, SP1 and SP2
SP1 has the following code:
declare @tmp as varchar(300)
set @tmp = 'SELECT * FROM
OPENROWSET ( ''SQLOLEDB'', ''SERVER=.;Trusted_Connection=yes'',
''SET FMTONLY OFF EXEC ' + db_name() + '..StoredProcedure'' )'
EXEC (@tmp)
SP2 has the following code:
SELECT *
FROM SP1 (which won't work because SP1 is a stored procedure. A view, a table valued function, or a temporary table must be used for this)
Views - can't use a view because they don't allow dynamic sql and the db_name() in the OPENROWSET function must be used.
Temp Tables - can't use these because it would cause a large hit on system performance due to the frequency SP2 and others like it will be used.
Functions - My last resort is to use a table valued function as shown:
FUNCTION MyFunction
( )
RETURNS @retTable
(
@Field1 int,
@Field2 varchar(50)
)
AS
BEGIN
-- the problem here is that I need to call SP1 and assign it's resulting data into the
-- @retTable variable
-- this statement is incorrect, but it's meaning is my goal
INSERT @retTableSELECT *FROM SP1
RETURN
END

In the SQL 7.0 Documentation is indicated that the UPDATE(<fieldname>), if
used in a isert/update trigger, it return TRUE or FALSE based on presence of <field> in the SET List, if the trigger was fired by an UPDATE operation, or in the list of field to fill, if the trigger was fired by an INSERT operation.
Below there is a piece of code that demostrate the false documentation
assertion in the case of a trigger fired by an INSERT operation, infact even
if i have specified only the FIELD1 in INSERT Statement the trigger Print in the screen that i have touched FIELD2 too.
Now the SP1 don't solve this BUG, even if i had read some month ago (before
that SP1 was out) that in SP1 this will be fixed!
Anyone Can Help me to solve this problem, indicating me where i can post the
problem to sensitize the Microsoft's Service Pack Factory ?
Thank in Advance
PS:Sorry for my Bad English .... correct me please if some part are not

I have a strange problem. I have some code that executes a sql query. If I run the query in SQL server query analyzer, I get a set of data returned for me as expected. This is the query listed on lines 3 and 4. I just manually type it into query analyzer.
Yet when I run the same query in my code, the result set is slightly different because it is missing some data. I am confused as to what is going on here. Basically to examine the sql result set returned, I write it out to an XML file. (See line 16).
Why the data returned is different, I have no idea. Also writing it out to an XML file is the only way I can look at the data. Otherwise looking at it in the debugger is impossible, with the hundreds of tree nodes returned.
If someone is able to help me figure this out, I would appreciate it.
1. public DataSet GetMarketList(string region, string marketRegion)2. {3. string sql = @"SELECT a.RealEstMarket FROM MarketMap a, RegionMap b " + 4."WHERE a.RegionCode = b.RegionCode"; 5. DataSet dsMarketList = new DataSet();6. SqlConnection sqlConn = new SqlConnection(intranetConnStr); 7. SqlCommand cmd = new SqlCommand(sql,sqlConn);8. sqlConn.Open();9. SqlDataAdapter adapter = new SqlDataAdapter(cmd); 10. try11. {12. adapter.Fill(dsMarketList);
13. String bling = adapter.SelectCommand.CommandText;//BRG 14. dsMarketList.DataSetName="RegionMarket"; 15. dsMarketList.Tables[0].TableName = "MarketList"; 16. dsMarketList.WriteXml(Server.MapPath ("myXMLFile.xml" )); // The data written to 17. myXMLFile.xml is not the same data that is returned when I run the query on line 3&4 18. // from the SQL query 19. } 20. catch(Exception e) 21. { 22. // Handle the exception (Code not shown)

Hey guys maybe you can help me out, been trying to figure this one out all day at work. I know how to use columns in a table to calculate another column in that same table. But I need to do some math on columns from a totally seperate table. Here is my scenario
table 1 = stock table
table 2 = Purchase order table
in table 2 there are line items that have ordered quantities for parts that we have ordered
in table 1 under each part number is a field for "quantity on order"
I need to compute the "quantity on order" in table 1 by summing all of the quantities in table 2 where the partnumber = the partnumber from table 1
quantity on order (table 1) = sum of all quantities (table 2) where the part numbers match
so for part number 516 i have this
table 2
poNumber partNumber quantity
1 516 1
2 516 12
3 516 4
table 1
partNumber inStock onOrder
516 0 17(this is what i am trying to figure out how to compute)
any help on this qould be appreciated. I would like the database to automatically do this itself if at all possible.

In recent testing, I have found that the trigger function UPDATE under SQL Server 6.5 SP5 behaves differently then SP4. For insert, the update function returns true on items that have not been explicitly inserted.
Is this a bug? Is this a new feature change? Where can I get more information on a bug list for SP5?

I'm a newbie to SQL and wanted to see if someone could help me write a query. I store historical options data in a SQL data base and I'm trying to create a query that will retrieve all ATM (at the money options).
For each unique stock symbol (STOCK_SYMBOL) in my database find the strike price (STRIKE) which is closest to the stock price (UND_LAST). This will be refined by the EXPIRATION and OPT_TYPE
The following query returns all options not just ATM options.
SELECT STOCK_SYMBOL, UND_LAST, STRIKE, EXPIRATION FROM DATA
WHERE EXPIRATION > '2007-02-01 00:00:00'
AND EXPIRATION < '2007-02-28 00:00:00'
AND OPT_TYPE = 'CALL'
Related DB fields.
STOCK_SYMBOL
STRIKE

I am using MS SQL Server 2005 Import and Export Wizard (.net framework Data Provider for mySAP Business Suite. )
as a interface between SAP and MS SQL 2005.
Once the connection is created i can use basic query to fetch the data from SAP tables
ie., SELECT * FROM AFPO
But say I want to EXTRACT data just for month of July from AFPO.
AFPO does not have date field so you have to join AFPO to AUFK and AUFK to COEP to fetch the date as a criteria to restrict data for the month of July .
This can be done in ABAP by view or Interim Table, if you have Developer Key.
Can anyone please tell me if aforesaid is possible with MS SQL Server 2005 Import and Export Wizard query ?

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.

dRow = deleted.Rows[0];
PKString = PKStringBuilder(PKTable, dRow);
foreach (DataColumn column in inserted.Columns)
{
//Build and Audit Entry
aRow = AuditTable.NewRow();
aRow["ActionType"] = "D";//D for Delete
aRow["TableName"] = TName;
aRow["PK"] = PKString;
aRow["FieldName"] = column.ColumnName;
aRow["OldValue"] = dRow[column.Ordinal].ToString();
aRow["NewValue"] = null;
aRow["ChangeDateTime"] = DateTime.Now.ToString();
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

Hello,
I want to find all the entries where the date field is a specific date; so I may have 5 entries with the date 1/1/2006, and I want to find all of those. However, datetime fields in SQL Server also have the time, so how do you handle that? Can you just say where requestdate = getdate() to get all of the entries that have records for today?
How does time affect this?

Hey,
What is the best way to query two datetime values to see if they are alike? I need to determine if an [AccountEndDate] is today (both values are datetime). Using "Like" does not work.
Thanks!

If you create a view such as CREATE VIEW TestView AS Select * FROM customers_table WHERE CustomerID between 213 AND 3443 Each time you want to select from the view - is the View going to perform the WHERE clause on the customers_table, or not? Or does the view already have the virtual rows?, meaning it does not have to perform a where clause (WHERE CustomerID between 213 AND 3443) on the customers_table, and just performs an inner join with the rows it already has?
