Pls Advise Me. HELP Pls...

May 20, 2006

on the 1st opening of my web page it uses the membership control of asp.net
for logging on. sometimes it takes time to logon and worse is, it will
encounter sql server error. that can be resolved by just restarting that
specific page and it will be alright, it will logon normally. this only issue happens only on the first opening of the logon page.
i have read a certain article and it says there that on the first time
you access the sql server, sometimes the sql server needs a little more
time communicating back and forth.
how can i make my log-on page wait a little longer till it communicates
or finishes communicating to the sql server?
im afraid that this may happen once i deploy my web project. i am
expecting over 100 users and they might save to the database all
together. will i encounter problem on this particular?
i am using ASP.NET 2.0 and SQLExpress for this project. pls advise me.
BIG THANKS.

Advise: DTS

Jul 20, 2005

Version: SQL Server 7.0App: MS Access 2000I created DTS to move records from MySQL to SQL Server (approx over 500,000+per months dataset) for purpose of canned and adhoc reporting. The apphave a simple interface using MS Access where user will input the timeframeof the dataset they will process.Both servers are physically located in the same bldg from another state.Previous to MySQL, they send us cd in text format and my app runs the DTSusing a BAT file containing the DTSRUN command. But I would like stay awayfrom the DTSRUN since they take awhile to load to the server, plus it runson background on client pc. I wanted a functionality where it will run onthe server without user supervision, and they can go about their businessand do something else. In other words, let the server do majority of thework.Now that MySQL came into the picture, the Network Support created a filedsnwhere sqlserver sits and I use that as a reference on my DTS (using UNC,\myserverfile$sample.dsn)The problem:1) I work from home and when creating and running this DTS's, it takes awhile to process;2) When specifying the UNC path on DTS and saved, for some reason itswitches to the User/System DSN section;3) I also tested from office with the same result (i connect using cablemodem)Now the only way I can think of to solve this problem:a) save the DTS as a file and send it over to Network Support and have themload it up and manually change the source location OR have them modify theDTS and change the source locationb) then create a DTS jobThe person who will be running this DTS might be running it from home oroffice. Also, is there a way to automate the DTS job using an SP? I wantedto make it as easier as possible for the end user, where all they have to dois enable the job and run only for this time and for this package.TIA!Bob

Certification: Looking For Advise

Oct 1, 2004

Hi All

I have been working with Ms access Database the last four years and have gained a lot of experience which help me to have extensive knowledge of Jet, Dao and Ado. Since The Begining of this year i hv been migrating to SQL server server and for that i bought two books :Programming Access project file with Microsoft Sql server and Access Developers Guide to Ms sql server : Chipman & Baron ( this oner is simply a great achievement ). They help me out in the very near past to complety migrate a two database approch Jet Application to a reliable (Adp/ SQL Server client server ) where major parts of the code business logic has been transfered to run on the server as stored procedures and all forms re-built as unbound. these merely leads to a great enhancement of the applications.

My goal now is register to MCDBA and get the certification. I am not interested by classroom training from Microsoft Parterns or online training. I am looking for books that can help to get well prepared for the exams.

Have found this two books in Amazon:

1 - MCAD/MCSE/MCDBA Self-Paced Training Kit: Microsoft SQL Server 2000 Database Design and Implementation, Exam 70-229, Second Edition

2- MCSA/MCSE/MCDBA Self-Paced Training Kit: Microsoft SQL Server 2000 System Administration, 70-228, Second Edition

However their rating didn't encourage me to place directly my orders.

Does someone have any experience with them ?

Do you think they will considerably help me to add value to my knowledge of SQL Server and get ready for the exam ?

Do you know some others books you woul rather encourage me to buy ?

Any advice in this regards really appreciated.

Need Advise On SSIS?

Jan 4, 2007

I am very new in SSIS. I have the Report Server set up with two dozen of the OLAP reports in it. The reports are connected to the OLAP database on a seperate computer running on Sql 2005 server and the data source for the OLAP DB is pointed to the warehouse database on another computer running on Sql 2000 server. The warehouse server updates daily from a number of "Production" Sql servers running on Sql 6.5 and Sql 7.0 with the legacy front-end data entry application. I know the update from the "Production" Sql 6.5/7.0 servers to the warehouse server complete around 9am in the morning everyday. How do I set up a package in SSIS to schedule the update of the OLAP database say 9:30am so that end-user can have the latest data to their report. The OLAP database has one fact table, half a dozen of cubes and ten dimensions. I know it is not an easy task to set up the package in SSIS. Please provide sample and step on how to do this. Thanks. One last question how to prevent/warn users from opening the report when SSIS updating the OLAP database?

SCD Design Advise

Jan 4, 2008

Hello,

I have a dimension table that, aside from its surrogate key (which is auto-generated using an identity column), has only one varchar column. I'd like to use an SCD Transform to insert only new output in the dimension, but this won't (?) work because I have no business key (the single varchar column comes from the SSIS pipeline), so my question is: how should I approach this problem? Is the design incorrect (e.g. should I generate the SK in the pipeline and use it as a business key?!), or am I doing something wrong in SSIS?

Thanks

Need Advise On Stored Procedure

Jul 27, 2005

Little rusty on my SQL but here is what I need.   Currently have a stored procedure that returns numerical data for 8 different element readings.    ( Carbon, Silicon, Sulfur, etc ).   This data is then put into a datagrid on an asp.net page and shows the readings for each test.On my asp .net page... they only want data that is out of the specified ranges to be shown ( EX:  > 1.6 AND < 2.0 ). Currently it is setup on the page to change the font color to red of data of its range but now they don't want data to be shown at all if for that one test everything is in its range.So how could I write my Where clause to check the 8 different element ranges and only need one of them to be true in order to show.Could I use an If / Then statement?Any help is appreciated.... Sorry this is quickly done but got to have it done soon.

Advise On Db Size And Logins

Nov 12, 2000

need advise on the following:
1) when creating a new db, and specifying the file growth what is the advantage and disadvantage of choosing MB as oppose to percent.
2) i am in the process of moving MS Access tables to sqlserver, and my access database is setup with a workgroup security. Is it a good method to make use of NT authentication instead of SQLserver logins or use both? Considering some of my forms have tab controls that restricts certain groups of users.

Any help is appreciated.

Advise On Querying A Database Daily

Jun 2, 2004

I am implementing an application that is looking into another System’s database (DBF). I need to query out new orders that have been put in daily. What is the best way to handle this situation? Should I write a service or have a trigger setup in MSDE? I just need to do a simple SELECT statement that grabs orders between a date range and update my SQL database (MSDE). I am not looking for specific code examples, just a solution.

What are my choices?

DTS Package Excel Connection - Please Advise

Feb 5, 2007

Hi,

I'm using MS SQL 2000 and I want to export data from MS SQL

database to MS Excel file. So, I choose the DTS package tool to do

this job.

I try to create the connection to the Excel file, which located in the

shared location by using the UNC path, e.g.

\servernamefoldernamefilename.xls However, I cannot provide the

username/password to connect to the file's location. So, the connection

does not work.

Do you have any idea how to create the Excel connection along with

shared username/password ?

Anyway, if it is not possible :o any advices about exporting MS SQL

data to MS Excel sheet via DTS packages are still welcome....

(The reason that I prefer DTS package bec. I can schedule the job

to run it automatically)

Thank you in advance.

Newby To DBA - Need Advise On Learning Position

Jan 4, 2008

Hello All,

I'm hoping you all can provide me with a little advice? I just landed my first DBA position with a company that runs different versions of SQL Server (7.0, 2000, 2005) on many different boxes. The databases I will be managing are in the 10-30TB ranges. Mostly the databases are for OLAP access by the company’s customers. I will need to bring myself up to speed on everything because there is no DBA at the company to transfer information.

Can anyone provide any advise on how I should approach this task of learning my position and/or useful links to resources? Thank you in advance!

Appreciate if someone could help me to address this issue?

One more thing, can i install the free SQL Express with Advanced Services on a normal desktop with Windows XP SP 2 and utilize it as a server or do i need a proper server with Windows 2003?

Thanks and Regards,

Schema Design For Product Specifications, Please Advise.

Feb 10, 2006

Here is the current schema.
product_category
   - product_category_id
   - other fields, ...
product
    - product_id
    - product_category_id
   - ....other fields
 
Now, for each product type, it has a distinct set of specifications. For example: Books type, will have author, publisher, pages, etc. Apparels type will have color, size, materials, etc. I don't think I can put all those specifications into one table - the product table above. 
How to design the schema to store product specifications? Should I create a separate spec table for each product type, such as book_product_spec, apparel_product_spec, electronics_product_spec, etc.? Please advise. Thanks.
