As we have INSERTED,DELETED tables to trace what values are inserted and deleted, how to write triggers for Updates on the tables.
Your help would be appreciated.

Hi, this SQL:
UPDATE [dbo].tblCommodity SET sImagePath .WRITE('abcdef', 0, 5)
gives me following error:
Cannot call methods on varchar.
I did it same way as it is in SQL Server Online Help :(
Thanks for ideas,

Hi, could someone explain to me with sample code how to write a sql query using parameters to update a record, as I am new to this.
thanks
I would like to write a query that will join two tables in separate databases (same server). Then update a field in one table using data and criteria from the other.
Its easy to do this in Microsoft Access by linking the tables using ODBC, but I found its not so simple to do directly in SQL Server
Thanks.
hi there, i have been wrestling with this for quite a while, as in my other post http://forums.asp.net/t/1194975.aspx, what someone advised me was to put in try catch blocks ot see whats going on, problem is i have never really done it whit this kinda thing before, and i was wondering if someone could point me in the right direction.
For example where would i put the try catch block in here, to show me if its not working public int getLocationID(int ProductID, int StockLoc)
{
// Gets the LocationID (Shelf ID?) for the stock column and product id
// passed
// The SQL will look Something like: string strSQL;
strSQL = "SELECT " + " location" + StockLoc + " " + "FROM " + " tbl_stock_part_multi_location " + "WHERE " + " stock_id = " + ProductID;string sConnectionString = "Data Source=xxxxx;Initial Catalog=xxxx;User ID=xxxx;Password=xxxxx";
SqlConnection objConnGetLocationID = new SqlConnection(sConnectionString);SqlCommand sqlCmdGetLocationID = new SqlCommand(strSQL, objConnGetLocationID);
objConnGetLocationID.Open();int intLocation = Convert.ToInt32(sqlCmdGetLocationID.ExecuteScalar());
return intLocation;
}
I have the following table:
CREATE TABLE [dbo].[IntegrationMessages]
(
[MessageId] [int] IDENTITY(1,1) NOT NULL,
[MessagePayload] [varbinary](max) NOT NULL,
)
I call the following insertmessage stored proc from a c# class that reads a file.
ALTER PROCEDURE [dbo].[InsertMessage]
@MessageId int OUTPUT
AS
BEGIN
INSERT INTO [dbo].[IntegrationMessages]
( MessagePayload )
VALUES
( 0x0 )
SELECT @MessageId = @@IDENTITY
END
The c# class then opens a filestream, reads bytes into a byte [] and calls UpdateMessage stored proc in a while loop to chunk the data into the MessagePayload column.
ALTER PROCEDURE [dbo].[UpdateMessage]
@MessageId int
,@MessagePayload varbinary(max)
AS
BEGIN
UPDATE [dbo].[IntegrationMessages]
SET
MessagePayload.WRITE(@MessagePayload, NULL, 0)
WHERE
MessageId = @MessageId
END
My problem is that I am always ending up with a 0x0 value prepended in my data. So far I have not found a way to avoid this issue. I have tried making the MessagePayload column NULLABLE but .WRITE does not work with columns that are NULLABLE.
My column contains the following:
0x0043555354317C...
but it should really contain
0x43555354317C...
My goal is to be able to store an exact copy of the data I read from the file.
Here is my c# code:
public void TestMethod1()
{
int bufferSize = 64;
byte[] inBuffer = new byte[bufferSize];
int bytesRead = 0;
byte[] outBuffer;
DBMessageLogger logger = new DBMessageLogger();
FileStream streamCopy =
new FileStream(@"C:vsProjectsSandboxBTSMessageLoggerInSACustomer3Rows.txt", FileMode.Open);
try
{
while ((bytesRead = streamCopy.Read(inBuffer, 0, bufferSize)) != 0)
{
outBuffer = new byte[bytesRead];
Array.Copy(inBuffer, outBuffer, bytesRead);
string inText = Encoding.UTF8.GetString(outBuffer);
Debug.WriteLine(inText);
//This calls the UpdateMessage stored proc
logger.LogMessageContentToDb(outBuffer);
}
}
catch (Exception ex)
{
// Do not fail the pipeline if we cannot archive
// Just log the failure to the event log
}
}
Hi,Is there a way to make a database write only, like in SQL server youcan make a DB read only? There is sensitive data which we want dontwant to read.What other alternatives can anyone think?Thanks.

I have a lot of databases under SQL Server Express 2005, reading an writing datas with VB6 (yes Visual Basic 6) and ADO (Provider SQLOLEDB). I do NOT install the SP2, but yesterday I install Silverlight and now I have SP2 on my SQL Server (9.0.3042) !?
Now I have a strange problem: I can read all datas, but I can't write any data to any tables.
Here a simple example:
I have a table "Professions", one column "RecNo" as int identity (1,1) with primary key and a column "Profession" as nvarchar(30).
Reading like this works:
Dim rcs As New Recordset
sTmp = "select * from Professions order by Profession"
rcs.Open sTmp, gcn, adOpenForwardOnly, adLockReadOnly
If rcs.RecordCount > 0 Then
Do
...
rcs.MoveNext
Loop Until rcs.EOF
End If
rcs.Close
Writing like this doesn't work anymore:
Dim lNewRecNo as long
Dim rcs As New Recordset
sTmp = "select * from Professions where RecNo = 42"
rcs.Open sTmp, gcn, adOpenKeyset, adLockOptimistic
If rcs.RecordCount < 1 Then rcs.AddNew
rcs!Profession = "XYZ"
rcs.Update
lNewRecNo = CNull2Val(rcs!RecNo)
rcs.Close
The rcs-object still give me the new record number after rcs.update, but the record is not in the database table. Adding a record in the Management Studio gives an error "row failed on retrieve on last operation". If I then click the button "Execute SQL" the new record is shown.
Another behaviour: Adding a row in the IDE like described above locks the Management Studio. From where I recieve a time out error then click the button "Execute SQL".
Any ideas whats wrong ?
This seems about the best place for my query however it does cross over a bit ... dont shoot me.
SQL 2000 sp4 on server 2003
dev env VB6

Mdac 2.8
I have a legacy app that required some simple ammendment, insert a single row of data into a simple table (Not rocket Science) Sample : insert into maintcon_mach (maintcon_id, mach_id, date) values (123, 456, getdate())
PK on maintcon_id, mach_id so that single relationship exists between maintcon_id and mach_id in the table.
The procedure above is followed by a verification procedure that checks to see if table maintcon_mach has a mach_id 456 against maintcon_id 123, this procedure returns true. So far so good, however if you step through the procedure till disconnecting from the database and then reconnect and do only the verification again, the data is missing.
The following steps to resolve have resulted in no improvement.
1. Verify MDAC in entire project and on users computers all 2.8
2 Remove transactions (just in case) and still the same.
3 Replace SQL insert with ADO (As below) and still the same.. tried this with and without transactions.
4 Tried referecing older MDACs
5 Installed SQLredist on sample machines and still the same.
rs.Open "maintcon_mach", conMach, adOpenForwardOnly, adLockOptimistic
With rs
.AddNew
!maintcon_id = lngmaint
!mach_id = lngMachID
!Date = Format(Now(), "yyyy-mm-dd")
.Update
End With
Is the problem in SQL or MDAC???
Perhaps I've missed something (Obviously have) but have run out of places to look... Any idea's
In advance ...thanx

repl.Dispose();
repl = null;
}
if (ReplicationComplete != null) ReplicationComplete(this, true);
}
catch(Exception ex)
{
if (ReplicationComplete != null) ReplicationComplete(ex, false);
}
}
Then later, if I try to update, insert or delete to the database, the application will hang. I can read from it, but I cannot write. If I close the application down and open it back up without replicating, I will not get any lockups. It also will not hang up after any replications prior to the create replication. I think I am doing something wrong in the initial replication that is holding on to some connection to the DB causing it to lock up. Has anyone seen anything like this before?
Hi there,
Does anyone know a way (a query perhaps?) to determine which logins have write permissions to a specific database on SQL Server 2005? Ive thought about joining sys.syslogins & sys.sysusers but looking at the columns, not sure which one would render me that info.
Any help is appreciated. Many thanks!
After a period of use (typically 1-2 hours), an application using SQL Server Express stops writing to the database, whilst still continuing to read from it. As far as I can tell, no error message is generated by any operation. The application is written in VB Express and is executed on several machines, with SQL Server Express on a central machine. Re-starting the application on the affected machine restores normal operation.
The problem on one machine does not cause a similar problem elsewhere at the same time (hence it appears to be an issue with the relationship between the application and SQL Server)
This does not appear to relate to the response to Q asked by sgcook on 9 may as we are not using user instances, but only a bare minimum connection string.
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 frdz, I m creating my web-application in asp.net with C# 2005 and using sql server 2005. I have created the stored procedure for the insert,update. I want to know how to write the mathematical calculations in the stored procedure.. Pls tell me from the below stored procedure were i m making the mistake ?? As the discount and the total amount are not calculated by itself....and stored in the database How to convert the @discpercent numeric(5,2) to@discpercent ="NoDiscount" should be displayed when no discount is being given to the customers.... ALTER PROCEDURE CalculationStoredProcedure
@accountid int output,
@accountname varchar(20),
@opbal numeric(10, 2),
@opbalcode char(2),
@total numeric(10, 2),
@clbal numeric(10, 2),
@clbalcode char(2),
@discpercent numeric(5,2),
@discamt numeric(10, 2)
as
begin
set nocount on
if @opbal IS NULL OR @opbal = 0
begin
select @opbal=0
select @opbalcode= ' '
select @clbal= 0
select @total= 0
select @clbalcode= ' '
@discpercent ="NoDiscount"
@discamt=0
end
select @accountid = isnull(max(accountid),0) + 1 from accountmaster
select @total=@opbal - @clbal from accountmaster
select @discamt=@total* @discpercent/100 from accountmaster
begin
insert into accountmaster
(
accountname,opbal,opbalcode,clbal,clbalcode
)
values
(
@accountname,@opbal,@opbalcode,@clbal,@clbalcode
)
end
set nocount off
end
Thanxs in adv...
How do I determine the read/write frequency on a database table? I am trying to do this on a 2012 and 2008 R2 servers.
View 2 Replies View RelatedHi to all DBAs,
I would like to ask if there will be a write and concurrency issue if i would create an online application with just one user connecting to the database, just like most open source php/mysql that can be downloaded
i.e
Setup 1. I will grant a single user that will connect to a database and will be set to a config.inc.php file and then create a table users (userid, username, password) and this table will be used for the application authentication and access control.
Setup 2. or is it much better to grant users that will connect to the database and have the table users for access control of the application?
to further illustrate my query:
Setup 1 would be:
###################Table: Users
user a@ipadd --> db1 --> userid mary --> myOnlineApp
user a@ipadd --> db1 --> userid john --> myOnlineApp
user a@ipadd --> db1 --> userid paul --> myOnlineApp
and Setup 2 would be:
#####################Table: Users
user mary@ipadd --> db1 --> userid mary --> myOnlineApp
user john@ipadd --> db1 --> userid john --> myOnlineApp
user paul@ipadd --> db1 --> userid paul --> myOnlineApp
will Setup 1 be enough if I will use SQL Server as database?
or Setup 2 is better user/database architecture?
This application will be online enrollment for a school with 16,000 students
very much appreciated for the feedbacks and suggestions

I am testing out a blank database created over two physical files on two separate disks with one table called data which has one column called values nvarchar(max).
I filled the table up with a whole load of data and ran a select * against it. If I run Permon at the same time I can see that the read load has been spread over multiple disks as each of these disks is getting read from in parallel. If I create the same database on a single file and run the same select * again it takes much longer, proving that the read load has been distributed across multiple disks.
Now moving onto writes, this is where the confusion lies. I understand that SQL server fills files evenly until they need growing, after which it will then fill files individually until they are full in a round robin fashion unless you have trace 1117 turned on. What I don't understand is why the writes aren't distributed out whilst it is filling these file groups.
I ran an continual insert into my table with go 1000000 to monitor how the files are being filled up. I monitored where SQL server was physically placing the files as they were being inserted by running the following query:
;WITH CTE AS
(SELECT
sys.fn_PhysLocFormatter (%%physloc%%) col1,
RIGHT(LEFT(sys.fn_PhysLocFormatter (%%physloc%%),2),1) AS [Physical RID],
DATAID
[Code] ....
I could see that it would a thousand or so records into file 1, then a thousand or so into file 2, then a thousand or so into file 1 etc etc. In another words it would hit one disk, then another disk, then back to disk one to fill the file evenly. Is there any way to make SQL Server distribute the writes out in parallel so that both disks are writing in tandem?
By the looks of it, multiple disks only scale reads, as with writes only one disk is ever written to at once which is annoying. Any way to harness the write power of multiple disks?
Hi,
I tried to backup the master key by the following syntax :
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'mypassword'
BACKUP MASTER KEY TO FILE = 'c: empmaster' ENCRYPTION BY PASSWORD = 'mypassword'
but it failed and i got the following message:
Cannot write into file 'c: empmaster'. Verify that you have write permissions, that the file path is valid, and that the file does not already exist.
NB: I am using the "sa" user to execute this command.
I know that we have a security permission issue , but where and how ?
