Auto Update To Sql Server Tables
Oct 22, 2004
I'm changing data storage for an asp.net project from MS Access to Sql Server. I've got the web site working, but I need to update the sql server tables with data from our Oracle db daily. What is the "best" way to do that?
I've read about DTS, but have never done anything like that. Would it be worth the time and effort to study? (So far I've created a package, with the import wizard, that doesn't work & I don't have the authority to delete :-)
I know I could create a dataset with my Oracle data and use that to update sql server. But is there a way to schedule an aspx to run authomatically? Would this affect performance? The sql server db isn't very big (30-40,000 records), but the Oracle db is & I need to do quite a bit of manipulation to the data.
This is new to me & I'm don't know what I should be searching for to find help. And if there is a more appropriate place to post this question, please let me know.
Thanks.

I have got 4 MS Access Database Files, which have got 3 Tables each, means Total 12 Tables which gets updated with new data every evening, by an external application. Means new data gets appended to all these 12 Tables.
I want to have exact same 4 Databases, which have got 3 Tables each, means Total 12 Tables, but WITHIN MS SQL SERVER. And then update all of these 12 Tables every evening, with the corresponding updates from the respective tables from the MS Access Databases.
I do not want to Manually Update all these 12 tables every evening into SQL Server. Hopefully there would be some easier method to do this in automatic manner.

I would like to create a auto relationship between tables.
Currently I am using Northwind DB with tables (Orders, OrderDetails, Customers)
Orders ( OrderId, Customerid)
OrderDetails(OrderId)
Customers(CustomerID)
Now, if the user wants to generate a relationship automatically based on SAME FIELD Names.
What is the approach?

I discovered the cause:
in SQL Server Enterprise Manager, open up db tree, right click the table, go - 'design' and set 'Identity' to yes.

Hi,
I am back with some more questions.
The structure is something like this -
Table 1 - dbo.DimHC_Team - This stores TeamID and TeamName
Table 2 - dbo.DimHC_Team_Config - This has TeamID TeamDate (not really used anywhere) TeamHeadCount (Max strength of a team)
Table 3 - dbo.DimHC_Team_Agg - This has TeamID, Team_Date (1st of every month, so that when I see the data for past months I use these dates) , Permanent Employees, Contracted employees, Open positions, Total, HeadCount.
Now, I have a stored procedure which goes like this -
declare @datevar datetime
declare @datevar2 datetime
declare @datevar3 datetime
declare @datevar4 datetime
select @datevar = DATEADD(dd, -(Day(getdate()) -1) ,getdate())
select @datevar = dateadd(dd, datediff(d,0,@datevar),0)
select @datevar2 = Dateadd(m , 1 , @datevar)
select @datevar4 = Dateadd(dd , 9 , @datevar2)
select @datevar3 = dateadd(m,2,@datevar)
select @datevar3 = dateadd(dd, -2 , @datevar3)
if (not exists (select * from dbo.DimHC_Team_Agg where Team_Date = @datevar2))
begin
insert into dbo.DimHC_Team_Agg
(TeamID, Team_Date)
select TeamID , @datevar2 from dbo.DimHC_Team_Config
end
update dbo.DimHC_Team_Agg
set Team_Head_Count = dbo.DimHC_Team_Config.Team_Head_Count
from dbo.DimHC_Team_Config, dbo.DimHC_Team_Agg
where dbo.DimHC_Team_Agg.Team_Date = @datevar2
and dbo.DimHC_Team_Config.TeamID = dbo.DimHC_Team_Agg.TeamID
update dbo.DimHC_Team_Agg
set
Perm_Posn = (select count(EmpType) from dbo.uview_DimHC_Emp_view1
where EmpStartDate < = @datevar4 and EmpType = 'Permanent'
and (EmpEndDate = '01/01/1753' or EmpEndDate > @datevar3)
and TeamID = '1'),
Contract_Posn = (select count(EmpType) from dbo.uview_DimHC_Emp_view1
where EmpStartDate < = @datevar4 and EmpType = 'Contractor'
and (EmpEndDate = '01/01/1753' or EmpEndDate > @datevar3)
and TeamID = '1')
......
What this block is doing is converting today's date to the first of this month. Going one month and 2 months in advance. Then it checks if any employee's start date < 10th of the next month and end date > 31st of the next month and if both the conditions are met then increments the employee count for that team as 1.
This TeamID is then repeated for 13 teams that I have right now. So that every month I will run it and it will update.
Now, I have 2 problems - First being that I had to write this block for 13 teams which isn't really a smart thing to do. Let's say I add a team tomorrow then I will need to modify this stored procedure and then tomorrow I may not be here, so the person who uses it should be able to do it easily. So, I wanted to know if I can loop or something through this with the max limit of TeamID coming from some external source and not like fix it to 20 or something.
Second, let's say in the beginning of this month I add a new team. The way I will do it is I will add it to dbo.DimHC_Team and dbo.DimHC_Team_Config table. Now, if I run this stored procedure then
if (not exists (select * from dbo.DimHC_Team_Agg where Team_Date = @datevar2))
is not going to return NULL as there will be entries with some teams right now. So this new Team won't be inserted in the dbo.DimHC_Team_Agg table and I will have to manually do it.
Can somebody help me as to how can I get over with these two problems?
Sorry for being really long but I thought it best to give all the details.

Hi all,
I'm using SQL 7, there is a setting on DB properties called "Auto update statistics", what kind of statistics does this refers to and how can this stats be accessed?
Thanks for your help!

Does anyone know how to tell how long it took for an auto update statistics to run? I looked under DBCC Show_Statistics and it shows the time the stats were last updated, but not how long it took to update them. Thanks.

I have a table that contains a field LastUpdated. This field should contains the date of the last update of the record.
Is there a way to auto-update this field value to the getdate() value each time the record is "touched" by an UPDATE sql command?
Thanks in advance,

Hi all,
We are using SQL Server 2005. The auto update statistics and auto create statistics for a database is set to ON. This database has a very heavy work load. When I checked the individual statitics , still the last updated statistics is in a old date value (few months ago).
Is it necessary to manually update the statistics for the same database? Or can we rely upon "auto update statistics" itself ?
Usually in what frequency the manual UPDATE STATISTICS should be run on production system which has heavy transactions ?
Thanks & Regards,
Hariarul

Recently a production server suffered a critical blocking period and I wanted to know if I could solicit some input. It seems that a stored procedure was in the middle of recompiling while and auto update statistics started. This caused blocking for like an hour on the
single object (stored procedure) that was originally called. The table that the update occurred on and that the
stored procedure is reading form is quite large. It is 2 mil rows and about 140 columns wide. Some info from
sysprocesses is below. The table alone takes up almost 4GB of space, when looking at sp_spaceused. I have some
questions.
1. Can the update statistics for a '_WA%' stats cause
blocking on a table?
2. Does an update stats on an index survive a restart of
SQL server? We tried restarting, but the blocking did not
end.
3. If the stored procedure is running under a compile, can
the server automatically start an update stats and cause
the stored procedure to wait?
4. Can the server automatically start an update stats on
more than one column stats at a time, causing one to be
blocked by the other?
5. We had never seen this issue before going to SQL2K
clustering. Is this something specific to SQL2K and not
SQL7 ?
Thanks for your input.

Hi guys,I followed the ASP.net official tutorial to create a DAL & Business Logic Layer (http://www.asp.net/learn/dataaccess/tutorial02cs.aspx). I have a table with a int ID field. I wish to write a function to add a new entry into this table but have the ID field auto-increment.The ID field is set as the Identity Column and has a Identity Increment & Seed of "1". If I manually go to the table and insert a new record leaving the ID value null it automatically increments. But if I create a C# function to add a new entry I get an error saying that the ID field can't be Null. Is there any way to use the Update method as shown on line 14 below to add a new entry but with it automatically incrementing? I did create a function called InsertDevice that simply inserts the other fields using a SQL INSERT and it auto-increments fine, just wondering if there is a way to do it using the DataTable and the Update method? Thanks for any help!!! 1 public bool AddDevice(string make, string model)
2 {
3 //cannot have the same device entered twice!
4 if (Adapter.FillDeviceCountByMakeModel(make, model) == 1)
5 return false;
6
7 RepositoryDataSet.DevicesDataTable devices = new RepositoryDataSet.DevicesDataTable();
8 RepositoryDataSet.DevicesRow device = devices.NewDevicesRow();
9
10 device.make = make;
11 device.model = model;
12
13 devices.AddDevicesRow(device); << Error thrown Here!
14 int rows_affected = Adapter.Update(devices);
15
16 return rows_affected == 1;

Hi,
I use the SqlDataSource Control for generating SQL-statements that I
easily can modify. But on some tables I cant autogenerate the
statements for Insert, Delete and Update. The checkbox is dimmed/not
enabled. Why cant I use the autogenerate feature on some tables?
Best regards,
I really like asp.net 2.0!

For my company, we have made it a standard to create history tables and triggers for the majority of our production tables. I recently grew tired of consistently spending the time needed to create these tables and triggers so I invested some time in creating a script that would auto generate these.
We recently launched a project which required nearly 100 history tables & triggers to be created. This would have normally taken a good day or two to complete. However, with this script it took a near 10 seconds. Here are some details about the script.
The code below creates a stored procedure that receives two input parameters (@TableName & @CreateTrigger) and performs the following actions:
1) Queries system tables to retrieve table schema for @TableName parameter
2) Creates a History table ("History_" + @TableName) to mimic the original table, plus includes additional history columns.
3) If @CreateTrigger = 'Y' then it creates an Update/Delete trigger on the @TableName table, which is used to populate the History table.

Over the past week and a half we started experiencing a sporadic slowdown in our production x64 SQL 2005 Ent. Edition server. Users started complaining of slowness then they started getting timeouts. In looking at sp_who2 and perfmon we saw the following during the slow/frozen periods:
* Dramatic increase in Perfmon Active Transactions
* CPU higher than norm, but not dramatically so
* sp_who2 shows a number of spids in SUSPENDED state (and not running waits)
* no blocking indicated from sp_who2
* active connections slowly increasing
* no disk queuing (or at most some spikes to 1)
After a couple of minutes of this we would then see the following:
* no more spids in SUSPENDED state
* Logins per second spikes dramatically
* Active transactions spikes down to "normal levels"
* CPU goes high then levels out at moderately higher than normal
* active connections slowly decreases back towards normal levels
* large spike in lock wait time
We turned on the Async Auto Update Statistics option (after testing in our staging environment) on the primary database about a week before we saw this problem. By turning it off we can visually see the problem go away by watching the above metrics. So my question is, What metrics can I use to see the "blocking" or resouce locking that is causing these problems?
Anyone?
Thx

I get the expected rows all rows that have "test" in the keyword.
On Sql Server 2005 Express new rows are not returned unless I rebuild the catalog.

I have a query, I am trying to update a certain column in my query you can see that is hard coded. The column that I am trying to update is "O_Test" I used a select statement trying to figure out how many records that accounts for with the entire database of all the tables. I got 643 records. So I am wondering if there is a way I can update all the columns without looking up each table and updating each one. This Update statement wont work because I am accounting for all records in the DB of all tables associated of what I hard coded
SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%O_Test%'
ORDER BY schema_name, table_name;

We are running a shopping mall in Korea and got a database including a table
of 4 million product prices, which is to be updated hourly basis. Updating 4million
records requires at least 10 minutes to complete. During the update, our shopping mall
exposed to customers does not respond quickly in fact very very slowly
and we investigated and found out that many tables of SQL database during the update were being
locked. As you know, site speed is top priority. We studied and found out that there are
two ways to avoid having locked tables during update, those are "read uncommitted" and
"snapshot" using the following lines.
set transaction Isolation level read uncommitted
set transaction Isolation level snapshot
We tried numerous times the above two lines and still find our tables being locked during update
and our customers are being disappointed.
My questions:
1. Is it possible at all in view of "the state of the art" to avoid having locked tables during update of 4 million records ?
2. if it is possible, would you please teach me like I am the beginner of database studies?
For your information, we are using 2005sql (64bit) in Windows 2003 (64bit).
Sincerely

I'm working on databases where statistics of some indexes (tables) are changing too frequently. Once I update them manually, one minute after they get 10-20% change, and five minutes after they get over 100% change. Tables get updated very frequently (multiple times in a second).
When I run a query to read from sys.stats, sys.dm_db_stats_properties and other dynamic views, I see that they were last updated when I did it manually, but the change rate overpassed the 500+20% (tables have multiples of 10K rows). Auto create and update statistics are set to true on all databases, and I don't know why sql server does not do that automatically.

I am trying to run an update statement against a vendor's database that houses HR information. If I run a regular select statement against the database with the following query, it returns without error:
SELECT "QUDDAT_DATA"."QUDDAT-INT", "NAME"."INTERNET-ADDRESS", "QUDDAT_DATA"."QUDFLD-FIELD-ID", "QUDDAT_DATA"."QUDTBL-TABLE-ID"
FROM "SKYWARD"."PUB"."NAME" "NAME", "SKYWARD"."PUB"."QUDDAT-DATA" "QUDDAT_DATA"
WHERE ("NAME"."NAME-ID"="QUDDAT_DATA"."QUDDAT-SRC-ID") AND "QUDDAT_DATA"."QUDTBL-TABLE-ID"=0 AND "QUDDAT_DATA"."QUDFLD-FIELD-ID"=16 AND "QUDDAT_DATA"."QUDDAT-INT"=11237When I try to convert it into an
[Code] ....
I am assuming I am receiving this error because it doesn't know where to find QUDDAT-INT? How can I fix that?
The "QUDDAT-INT" column houses the employee number. So in the case of the SELECT query above, I am testing against a specific employee number.

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.

I need to search for such SPs in my database in which the queries for update a table contains where clause which uses non primary key while updating rows in table.
If employee table have empId as primary key and an Update query is using empName in where clause to update employee record then such SP should be listed. so there would be hundreds of tables with their primary key and thousands of SPs in a database. How can I find them where the "where" clause is using some other column than its primary key.
If there is any other hint or query to identify such queries that lock tables, I only found the above few queries that are not using primary key in where clause.

We have 20 -30 normalized tables in our dartabase . Also we have 4tables where we store the calculated data fron those normalised tables.The Reason we have these 4 denormalised tables is when we try to dothe calcultion on the fly, our site becomes very slow. So We haveprecalculated and stored it in 4 tables.The Process we use to do the precalcultion, will get do thecalculation and and store it in a temp table. It will compare the thetemp with denormalised tables and insert new rows , delte the old oneans update if any changes.This process take about 20 mins - 60mins. Ittakes long time because in this process we first do the calculationregardless of changes and then do a compare to see what are changed andremove if any rows are deleted, and insert new rowsand update thechanges.Now we like to capture the rows/columns changed in the normalisedtables and do only those chages to the denormalised table , which weare hoping will reduce the processing time by atleast 50%WE have upgraded to SQL SERVER 2005.So We like to use the newtechnology for this process.I have to design the a model to capture the changes and updated onlythose changes.I have the list of normalised tables and te columns which will affectthe end results.I thought of using Triggers or OUTPUT clause to capture the changes.Please help me with the any ideas how to design the new process
