Table Upate/insert Scenario
Oct 24, 2007
Hi,i am using sql 2005 and this is what i am trying to do..i have multiple table say tbl1,tbl2,tbl3 etc and each one of have columns say col1,col2,col3,col4,col5 etc... and table_total.Each of these table contain same forignKey,say col2, and gets populated different time.
In table_total i need to store the sum of particular column/columns(like sum of col3 from tbl1 and sum of col3 and also sum of col4 from tbl2 )values in a given row,for a given foriegn key under the respective column in table_total. Something like table_total has columns sum_col3tbl1, sum_col4tbl2, sum_col4tbl3, sum_col5tbl2 likewise..table_toal should get updated at the same time,whenever tbl1,tbl2,tbl3 etc..are getting updated,so that it always has most updated value.Can someone suggest me how to achive this? thanks...

I have a store procedure to create a table temp, populate data from Origin1 table, and then add a new column SSN to temp table, update the SSNs from another table. but the following code gives error, pleaes help!
Create table temp (
....
)
Insert into temp
select * from Origin1
Alter table temp ADD Name int
Update temp
Set SSN = (select SSN from Origin2
where id = Origin.id)
it gives 'Invalid column name: 'SSN'
I am aware that the add new column doesn't take effect until end of the SP, but there must be a way, Thanks for any inputs.

I began with a partition function as follows:
CREATE PARTITION FUNCTION [TimeTicksRangePFN](bigint) AS RANGE RIGHT FOR VALUES (633294720000000000, 633320640000000000, 633347424000000000, 633374208000000000, 633399264000000000)
These numbers happen to correspond to the dates 11/1/7, 12/1/7, 1/1/8, 2/1/8 and 3/1/8 in ticks respectively.
I began with a partition scheme as follows:
CREATE PARTITION SCHEME [TimeTicksRangePScheme] AS PARTITION [TimeTicksRangePFN] TO ([FG_xxx_EventArchive00001], [FG_xxx_EventArchive00002], [FG_xxx_EventArchive00003], [FG_xxx_EventArchive00004], [FG_xxx_EventArchive00005], [PRIMARY])
While running my “sliding window script� , which I hoped would 1) roll off the oldest partition of my EventArchive table and 2) add a new partition with a tick boundary that equates to 3/5/8, I get an error related to my switch out table's index, the same table's Filegroup and Primary.
After getting the error, I scripted the partition function as a create in mgt studio and got…
CREATE PARTITION FUNCTION [TimeTicksRangePFN](bigint) AS RANGE RIGHT FOR VALUES (633320640000000000, 633347424000000000, 633374208000000000, 633399264000000000, 633402720000000000)
...which looks like what I had intended cuz the last boundary is the tick representation of 3/5/8 and the oldest has rolled off
scripting the scheme produced...
CREATE PARTITION SCHEME [TimeTicksRangePScheme] AS PARTITION [TimeTicksRangePFN] TO ([FG_xxx_EventArchive00001], [FG_xxx_EventArchive00003], [FG_xxx_EventArchive00004], [FG_xxx_EventArchive00005], [PRIMARY], [FG_xxx_EventArchive00001])
which looks nothing like what I intended, I thought I’d end up with …00002,…00003,…00004,…00005,…00001,PRIMARY
the script steps that seem most relevant start at the 5th step as follows...
5) creates table [dbo].Switch on the switch out filegroup with columns, PK and indexes matching exactly those of [dbo].EventArchive
6) switches partition 1 of [dbo].EventArchive to [dbo].Switch
7) ALTER PARTITION FUNCTION TimeTicksRangePFN() MERGE RANGE (633294720000000000) --this was the oldest date corresponding to 11/1/7
8) truncates [dbo].Switch
9) drops all indexes on [dbo].Switch except a clustered index (IX_TimeTicks), leaves PK constraint alone
10) ships the new data whose values range from 3/1/8 to less than 3/5/8 to [dbo].Switch and deletes them from their source
11) recreates all non clustered indexes on [dbo].Switch
12)ALTER TABLE [dbo].[Switch] WITH CHECK ADD CONSTRAINT RangeCK CHECK ([TimeTicks] < the number of ticks represented by 3/5/8)
13)ALTER PARTITION SCHEME TimeTicksRangePScheme NEXT USED [FG_xxx_EventArchive00001] --fg isnt really hardcoded
14)ALTER PARTITION FUNCTION TimeTicksRangePFN() SPLIT RANGE (the number of ticks represented by 3/5/8)
15)ALTER TABLE [dbo].[Switch] SWITCH TO [dbo].[EventArchive] PARTITION 5
step 15 is the one that fails with message "ALTER TABLE SWITCH statement failed. index 'xxx.dbo.Switch.IX_TimeTicks' is in filegroup 'FG_xxx_EventArchive00001' and partition 5 of index 'xxx.dbo.EventArchive.IX_TimeTicks' is in filegroup 'PRIMARY'.

After running my €œsliding window script€? , which I wanted to switch out the lowest partition with, and add a new partition with a new tick boundary that equates to 3/5/8, I get an error saying that 1 of my switch out table€™s indexes is in filegroup 1 but partition 5€™s index of the same name is in PRIMARY. At this point the partition function looks like€¦

the relevant script steps are...

6) switches partition 1 of [dbo].EventArchive to [dbo].Switch
7) ALTER PARTITION FUNCTION TimeTicksRangePFN() MERGE RANGE (633294720000000000)
8) truncates [dbo].Switch

Hi,
i have a scenario where I have to read 2 files that update the same table (a temp staging table)...this comes from the source system's limitation on the amount of columns that it can export. What we have done as a workaround is we split the data into 2 files where the 2nd file would contain the first file's primary key so we can know on which record to do an update...
Here is my problem...
The table that needs to be updated contains 9 columns. File one contains 5 of them and file2 contains 4 of them.
File 1 inserts 100 rows and leaves the other 4 columns as nulls and ready for file 2 to do an update into them.
File 2 inserts 10 rows but fails on 90 rows due to incorrect data.
Thus only 10 rows are successfully updated and ready to be processed but 90 are incorrect. I want to still do processing on the existing 10 but cant affort to try and do processing on the broken ones...
The easy solution would be to remove the incorrect rows from the temp table when ever an error occurs on the 2nd file's package by running a sql query on the table using the primary keys that exist in both files but when the error occurs on the Flat File source, I can't get the primary key.
What would be the best suggestion? Should i rather fail the whole package if 1 row bombs out? I cant put any logic in the following package that does the master file update/insert from the temp table because of the nature of the date. I
Regards
Mike

table2 is intially populated (basically this will serve as historical table for view); temptable and table2 will are similar except that table2 has two extra columns which are insertdt and updatedt
process:
1. get data from an existing view and insert in temptable
2. truncate/delete contents of table1
3. insert data in table1 by comparing temptable vs table2 (values that exists in temptable but not in table2 will be inserted)
4. insert data in table2 which are not yet present (comparing ID in t2 and temptable)
5. UPDATE table2 whose field/column VALUE is not equal with temptable. (meaning UNMATCHED VALUE)
* for #5 if a value from table2 (historical table) has changed compared to temptable (new result of view) this must be updated as well as the updateddt field value.

An insert statement was not inserting all the data into a table. Found it very strange as the other fields in the row were inserted. I ran SQL profiler and found that sql statement had all the fields in the insert statement but some of the fields were not inserted. Below is the sql statement which is created dyanmically by a asp.net C# class. The columns which are not inserted are 'totaltax' and 'totalamount' ...while the 'shipto_name' etc...were inserted.there were not errors thrown. The sql from the code cannot be shown here as it is dynamically built referencing C# class files.It works fine on another test database which uses the same dlls. The only difference i found was the difference in date formats..@totalamount=1625.62,@totaltax=125.62are not inserted into the database.Below is the statement copied from SQL profiler.exec sp_executesql N'INSERT INTO salesorder(billto_city, billto_country, billto_line1, billto_line2, billto_name,billto_postalcode, billto_stateorprovince, billto_telephone, contactid, CreatedOn, customerid, customeridtype,DeletionStateCode, discountamount, discountpercentage, ModifiedOn, name, ordernumber,pricelevelid, salesorderId, shipto_city, shipto_country,shipto_line1, shipto_line2, shipto_name, shipto_postalcode, shipto_stateorprovince,shipto_telephone, StateCode, submitdate, totalamount,totallineitemamount, totaltax ) VALUES(@billto_city, @billto_country, @billto_line1, @billto_line2,@billto_name, @billto_postalcode, @billto_stateorprovince, @billto_telephone, @contactid, @CreatedOn, @customerid,@customeridtype, @DeletionStateCode, @discountamount,@discountpercentage, @ModifiedOn, @name, @ordernumber, @pricelevelid, @salesorderId,@shipto_city, @shipto_country, @shipto_line1, @shipto_line2,@shipto_name, @shipto_postalcode, @shipto_stateorprovince, @shipto_telephone,@StateCode, @submitdate, @totalamount, @totallineitemamount, @totaltax)',N'@billto_city nvarchar(8),@billto_country nvarchar(13),@billto_line1 nvarchar(3),@billto_line2 nvarchar(4),@billto_name nvarchar(15),@billto_postalcode nvarchar(5),@billto_stateorprovince nvarchar(8),@billto_telephone nvarchar(3),@contactid uniqueidentifier,@CreatedOn datetime,@customerid uniqueidentifier,@customeridtype int,@DeletionStateCode int,@discountamount decimal(1,0),@discountpercentage decimal(1,0),@ModifiedOn datetime,@name nvarchar(33),@ordernumber nvarchar(18),@pricelevelid uniqueidentifier,@salesorderId uniqueidentifier,@shipto_city nvarchar(8),@shipto_country nvarchar(13),@shipto_line1 nvarchar(3),@shipto_line2 nvarchar(4),@shipto_name nvarchar(15),@shipto_postalcode nvarchar(5),@shipto_stateorprovince nvarchar(8),@shipto_telephone nvarchar(3),@StateCode int,@submitdate datetime,@totalamount decimal(6,2),@totallineitemamount decimal(6,2),@totaltax decimal(5,2)',@billto_city=N'New York',@billto_country=N'United States',@billto_line1=N'454',@billto_line2=N'Road',@billto_name=N'Hillary Clinton',@billto_postalcode=N'10001',@billto_stateorprovince=N'New York',@billto_telephone=N'124',@contactid='8DAFE298-3A25-42EE-B208-0B79DE653B61',@CreatedOn=''2008-04-18 13:37:12:013'',@customerid='8DAFE298-3A25-42EE-B208-0B79DE653B61',@customeridtype=2,@DeletionStateCode=0,@discountamount=0,@discountpercentage=0,@ModifiedOn=''2008-04-18 13:37:12:013'',@name=N'E-Commerce Order (Before billing)',@ordernumber=N'BRKV-CC-OKRW5764YS',@pricelevelid='B74DB28B-AA8F-DC11-B289-000423B63B71',@salesorderId='9CD0E11A-5A6D-4584-BC3E-4292EBA6ED24',@shipto_city=N'New York',@shipto_country=N'United States',@shipto_line1=N'454',@shipto_line2=N'Road',@shipto_name=N'Hillary Clinton',@shipto_postalcode=N'10001',@shipto_stateorprovince=N'New York',@shipto_telephone=N'124',@StateCode=0,@submitdate=''2008-04-18 14:37:10:140'',@totalamount=1625.62,@totallineitemamount=1500.00,@totaltax=125.62

Is there a way to avoid entering column names in the excel template for me to create an excel file froma dynamic excel using openrowset.
I have teh following code but it works fien when column names are given ahead of time.
If I remove the column names from the template and just to Select * from the table and Select * from sheet1 then it tells me that column names donot match.
Server: Msg 213, Level 16, State 5, Line 1Insert Error: Column name or number of supplied values does not match table definition.
here is my code...
SET @sql1='select * from table1'SET @sql2='select * from table2'
IF @File_Name = '' Select @fn = 'C:Test1.xls' ELSE Select @fn = 'C:' + @File_Name + '.xls' -- FileCopy command string formation SELECT @Cmd = 'Copy C:TestTemplate1.xls ' + @fn

I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual

For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.

Hi
I am trying to use multiple insert for a table T1 to add multiple rows.
Ti has trigger for insert to add or update multiple rows in Table T2.
When I provide multiple insert SQL then only first insert works while rest insert statements does not work

Help please!
I have an asp page with some simple vbscript to add a record to a table, the record has a datefield (dob).
the insert results in a US formated date if I add a record to a dynamic recordset but a UK formated date if I insert direct to the table ?????
i.e.
if request("dob") is "01/11/2007" (1st november 2007)
set conn = server.createobject("adodb.connection")
set rs = server.createobject("adodb.recordset")
rs.open "tez", mc, 2, 2 rs.addnew
rs("dob") = request("dob")
rs.update
11 jan 2007 stored in table
while
set trs = Server.CreateObject("ADODB.RecordSet")
qfn= "insert tez values('"+request("dob")+"')"
trs.Open qfn,mc
results in
1 november 2007 is written to the table.
Both of these methods are used in the same asp page.
This is on a windows2003 server, sql2005,iisv6, asp.netv2
I have tried every setting I can find in iis,asp,sql server to no avail.
I need the recordset method to work correctly.

Consider the following scenario:
I got 2 webservers (2003) using NLB.
I want some kind of common data store (SQL Server).
I need this data store to be fault tolerant.
I don't have any more machines.
I don't have an enterprise licence for windows.
How do I solve this???

I have a company with 5 offices connected with a dedicated line (500+ employees).
They have five databases, one in each office.
Now they want a new application which will replace the old (VB6 on MySQL will now be VB.NET 2.0 with MS SQL Server 2005).
The want all the data availiable in all the offices. We will still have 5 databases in 5 offices, but all with the same data.
Sometimes the dedicated line is lost.
Now I have a few questions:
Will the database be still running while a line is down?
Will the database be still running if replication is of type Merge (instead of continuesly).
Is it good practice to use unique identifiers versus Numeric keys?
Is it good practice when the application uses the "master" database to save global things like "Suppliers" and the local database to add and change Orders?
Do you have some recommended reads?
Thx for your time!

For High Protection mode (2servers, no witness, FULL safety), in the event of a catastrophic failure of the principal, can a remote (but well connected) mirror be forced to assume the principal role? The MS manual "Database Mirroring in SQL Server 2005" on p2 says the failover type for HP mode is manual only (as opposed to forced). Elsewhere it seems to seems suggest otherwise but there is no clear and unambiguous discussion describing the exact procedure.
Can anyone clarify this matter? Thanks,

I currently have a workflow "like" application which uses msmq to pass messages to each step transactionally. I'd like to take advantage to something like SSB to make the app scale. Here's how it works today:
Start Workflow WebService puts message on queue.
Windows Service has threaded listeners on each queue for the workflow.
The listeners do a transactional Receive off the queue. By doing this is in a transaction, we can enforce that only one listener will pick up and process the message. Once they have a message they call a .Net Assembly to perform some work. Once the work is performed succesfully, the listeners put the work context on the next queue using the same transaction as the receive and commit the transaction effectively removing the message from the receive queue permanently. If a fatal error occured during processing, the work context is moved to an error queue transactionaly. If the process blew up due to other reasons, the transaction is rolled back and the message reappears on the original queue so that another instance of the service can pick it up. Currently all this is running on one instance of the Windows service and cannot span more than one host machine since MSMQ did not support transactional reads off public queues without using DTC.
I saw the external activator sample and it looks great but I have a few questions. First, I'd have to modify it to call assemblies instead of external processes. No biggie there. One other requirement that one and only one receiver should process the message and that when the next message is sent to the next queue, it's done within the same transaction as the receive. I hope that this can be done without any deadlocks. I also saw mentioned somewhere that this messaging could advantage of the local SQLExpress instances so that even if the main SQL Server instance is down, the messages can go out. Last requirement is that our message is a blob (serialized .Net object) so how do we define that kind of message?
Thanks

Table1: WriterID, WriterName, WriterSurname
Table2: BookID, WriterID, BookName, Category
Table3: CategoryID, CategoryName
There will be one form. Which way i should use to enter data from one form to multiple tables with same WriterID.
1.) Should i use SqlCommand class and a Stored Procedure?
( Like that: http://www.aspnet101.com/aspnet101/tutorials.aspx?id=13 )
2.) Is there another way without a stored procedure? I can't imagine how to insert same form to multiple tables. In real scenario there are lots of table and all contains a column that holds same value such as WriterID.

Hi, I want to know the a solution for my Synchronization Scenario
I have a several client databses which are SQL Server 2005 Express and i have a master database which is SQL Server 2000 containing all the individual Client databases. All the individual client databases are kept seperately at the master location. I need to Synchronization the client database with its copy at the master database (something like Merge replication). Both the Client Copy as well as Master Copy could be Publishers & Subscribers.
Now the problem is Because of security & firewall issues, only the Client should have the ability to schedule & initiate the synchronization process with the master copy. Unfortunately SQL Server 2005 Express has only subscriber agent and not a publisher agent.
Any help on how to achieve this would be appreciated . Thank You

Hello All ..
This is the scenario I'm having :
-- I'm a beginner so bear the way I'm putting it ... sorry !
* I have a database with tables
- company: CompanyID, CompanyName
- Person: PersonID, PersonName, CompanyID (fk)
- Supplier: SupplierID, SupplierCode, SupplierName, CompanyID (fk)
In the Stored Procedures associated (insertCompany, insertPerson, insertSupplier), I want to check the existance of SupplierID .. which should be the 'Output' ...
There could be different ways to do it like:
1) - In the supplier stored procedure I can read the ID (SELECT) and :
if it exists (I save the existing SupplierID - to 'return' it at the end).
if it doesn't (I insert the Company, the Person and save the new SupplierID - to 'return' it at the end)
------------------------------------
2) - Other way is by doing multiple stored procedures,
. one SP that checks,
. another SP that do inserts
. and a main SP that calls the check SP and gets the values and base the results according to conditions (if - else)
3) it could be done (maybe) using Functions in SQL SERVER...
There should be some reasons why I need to go for one of the methods or another method !
I want to know the best practice for this scenario in terms of performance and other issues - consider a similar big scenario ..... !!!
I'll appreciate your help ...
Thanks in Advance . ! .

How can I be able to use "NewReceivedTime" as a variable?
Since having to create a new column using CASE statement in SQL would mean that user will not be able to use this new column name and having to receive error such as "Invalid Column Name: NewReceivedTime "
(case
when <value>
else <value>
end) as NewReceivedTime
I'm asking this because, I would want to use "NewReceivedTime" I've created to equate to another Time Column like
NewReceivedTime = LogDateTime something like that.
Thanks.

What I'd like to do is use SQL Express as a back-end for an existing Access 2003 application. The application is currently a single-file Access solution. I'm just investigating options to separate the front-end from the back-end so that the users can access a single data store from multiple PCs. We're only talking about maybe 5 users total, and really no more than 2 accessing it simultaneously at any given time (although the same setup exists in several offices). Right now they are just opening the Access db from a fileshare. This has resulted in corruption on a few occasions, which is part of the reason for wanting to replace the current solution with something that will be a little more robust. I'm wondering if there is a way to deploy a SQL Express db on a fileshare so that it can be connected to by the Access front-end. While we can install things on their desktops, we can't install anything on the file server, we can just put files there. Is there any way that I could make that solution work, or should I just stick with separating the Access front-end and back-end?
Thanks,
Kris

Hi all,
I have a huge replication task I need to perform. The source table has over 250,000,000 records and everyday approximately 400,000 records are added to the system regularly.
Currently, I am running snapshot replication and it's taking 10 to 11 hours to complete (The internet connection between the production and the report server is slow). The reason I am using this method is because the source table does not have a timestamp column (so I can run an incremental replication) and I cannot modify that table because it belongs to a third party software. It does have a field which is linked to another table holding the timestamp.
Here is the source table and the other table's structure for reference:
DataLog
Name Datatype Size
DataLogStampID int 4
Value float 8
QuantityID smallint 2
DataLogStamp
ID (Which is foreign key to DataLogStampID field in the above table) int 4
SourceID smallint 2
TimestampSoruceLT datatime 8
What I would like to know is, what is the best practice to handle such replication with MSSQL Server 2000.
I am thinking of developing a procedure which follows the following step using a temp table:
This procedure will run (say) every night.
The temp table will contain a timestamp field.
For one time only, I will run a snapshot replication, so that I can have the existing data into the destination db.
I will record this timestamp into a repl_status table which holds the timestamp of the last replication.
The procedure will read the record from repl_status and select all records from the source table which were added since this date and put them into a new temp table (this table will have the same structure as the source and destination tables) and then a snapshot replication will "add" these new records only every night to the dest. table. By using this method, I will only transfer the records which have been added since the last replication (last night - less records).
Any comments would be greatly appreciated.
Thanks for your time in advance,
Sinan Topuz

Hi,
I'm about to implement a DB Mirroring on my production server.and i'm wondering about the scenario what will happen if.
1. if my primary server suddenly die.how i can operate the mirror DB without losing data?
2. when the primary server comes to life, how i make the primary server to lead again with the DB Mirroring?(do i need to recreate all procedures of DB Mirroring again)
3. how can i be sure that the DB mirroring is indeed mirrored on the drp server?
4. what about alerting - can i be notified via email if the DB Mirroring isn't sync? or if the drp server is down and other issues that can be occur .
Thx

Hi,
I have a product basket scenario in where I have to recommend contracts to a customer based on the product and the quantity he/she buys. Product Quantity is an important factor which administers the user in the purchase of a particular contract
I have the following tables with me.
Customer product transaction table, Customer Contract transaction table but there is no direct relationship between contract and product in the database. The only way the two can be linked is through the customer.
If I create a mining structure with Customer-Product information as the nested table and Customer-Contract information as the nested table with customer being the link between the two, the model is showing some irreverent contract recommendations.
what is the solution for the above problem? Is it because the is no direct relationship between the product and the contract?
How can I overcome this problem?

Hello All
We have Asynchronous DB Mirroring established for our Production database
which runs on SQL Server 2005.
For the DR Test we plan to do the following during the period of low activity :
1. Pause the mirroring on the Principal Server.
2. Break the mirror on the Mirror Server
3. Take on offline backup on the Mirror.
4. Bring the Mirror Database up.
5. Run the DR Tests on the Mirrored Database
6. Restore the Offline Backup taken in step 3.
7. Reestablish the mirror from the Principal to Mirror.
8. Resume Mirroring on the Principal Server.
9. Verify Mirroring is happening on the Mirror Server
Can u please let me know if this plan is feasible and if there should be any modifications to the plan that are required. Any other suggestions/input is appreciated.
TIA
Best,
Jay

we have a pretty vast t-sql statement that queries out production db and inserts results into a reporting table on the same db. the problem we're having is that during this process there are several locking processes engaged (key, table, schema, etc). i thought by moving this entire process to a seperate (reporting) database i could bypass this locking problem. however, the same problem exist in the reporting database. is there a way to disable all locking (this is just a reporting database so im not worried about the data integrity. any suggestions to disable all locking? by the way its a sql 2000 server.
example:

Hi all,
We are about to start a project that will involve three websites, each of which will have its own public domain name and two of which will act as e-commerce applications. Both e-commerce applications will only contain relatively small amounts of data (few thousand products, up to 15000 customer records with basic order history) and will be synchronised with a central data server at another site that will be responsible for handling payments, order processing, invoicing, etc.
The sites will take approx 500 hits every 24 hours and we will need to manage the DNS on the hosting server.
My question is, would we be ok to host these sites on a Web Edition of Windows 2003 Server with SQL Express, or is there any clear reason that we should go with the Standard editions of Windows Server and/or SQL?
Regards,
Stephen.
