Hi there
I am up against a condition where my control flow should be divided into threads and depending on value of a variable i have to choose 1 of the threads.
Its something like
if a =1 then execute this
else execute this one.
Thanks and Regards

I have a requirement to be able to calculate the transit time between international locations when I have the flight departure time and flight arrival times and departure and arrival locations.
We have a problem though, in that the datetime stored are local times, and the journeys can involve crossing the international date line in either direction, so it is possible for the arrival time to be earlier than the departure time!
To give a famous example, if you flew Concorde from London to Washington, you could depart at 10am on the 1st of June (London time) and arrive at 8.00am on 1st June (Washington time)
Even worse, you could leave Brisbane at 2.00 am on the 1st June, cross the International Date Line and arrive at San Francisco at 23:00 on 31st May!
Last year I created an online newsletter for my company using word (doc, not html) and sent it through send to: with Outlook to our staff. It worked great - however the width was always smaller than the viewable area. Not having a measurement of pixels or resolution to determine width in my layout - how do I accurately adjust my width in a word doc to adequately size to the viewable screen of my audience?
Any advise is appreciated.
Thanks,

When trying to install Business Contact Manager (BCM) for Outlook 2007, the setup failed and I was refered to a log file in my Local Settings/Temp folder. The log actually says that Business Contact Manager was installed sucessfully! BCM is supposed to install SQL Express 2005 as an instance or as instance if SQL Express is already installed. There is an MSSMLBIZ instance in Services..
Who can I send the Log File to for analysis and the fix feedback?
When I first went into Computer Management and clicked on Services and Applications in the left panel, the error message appeared "Snap-in failed to intialize. Name: SQL Server Configuration Manager CLSID:{CA9F8727-31DF-41D2-975C-887D84903967} This message diappeared when I clicked on Services and Applications again. Under Services, there are 3 SQL services - one is an application that was uninstalled 3-4 weeks ago and I disabled this service. The other 2 are: SQL Server (MSSMLBIZ) and the other one is SQL Server (SQLEXPRESS) When I tried to start either of the last 2, the message appeared: Services "Could not start the SQL Server (MSSMLBIZ) service on Local Computer. Error 3: The system cannot find the path specified. Under Program Files/Microsoft SQL Server/MSSGL.1 folder is mostly empty. So, it seems like the Path in the Registry is not valid and that nothing is being installed in the MSSQL.1 folder. If so, how do I fix this?
How do I get the BCM SQL instance to install and run properly? what do the messages in Services mean and how do I resolve these.
Thank you!

I have a production server log shipping to a secondary server every 30 minutes (both SQL 2000), which the second server is used for both a warm standby server and for reporting from users. Issue: the log shipping locks the DB so reporting can't be done until the load is finished, the load to the second set of databases has taken up to 15 minutes to finish allowing the users only 15 minutes to run reports, this is not acceptable. The server also needs to be used for DR.
I am looking for another solution, I can't use Transactional Log shipping as not all of the tables in the databases have a primary key identified. So, I am looking for a real-time or near real-time reporting server that is more available to running reports and a warm standby server for Disaster recovery. I am trying to figure out what SQL Server 2000 has to provide (or even 2005 or 2008?) or I am also looking at some third party software, but not sure what is the best for a reasonable price.
Any help is appreciated.
Thanks....JB
Hi All,
I have a dilemn:
On one side, I have a column C1 which could be a primary key because it is never null, the value is unique and identify the record. The problem is its a char type and its lenght can be close to 30.
Then, I've planned to add another column C2 of int type as PK. But then I need to add a unique constraint index on C1. Does it improve performance anyway?
Thanks
good day, everyone
if i have a transaction table with fields below :
transaction_no, product_id, product_desc, product_qty, product_txn, transaction_date
can some expert here point out to me , which is the best cluster-index and non-clsuter index ?
and possible kindly please explain why is it so? i'm not good in database so just explain like to beginner
thank you very much for guidance
(Hard to put a good subject on this one...)
I have a database containing a lot of users and these users can have four different kind of telephone numbers connected to them: "Direct phone", "Switchboard", "Cell phone", "Home phone". The phone numbers are stored in a separate table. Some users have 0 phone numbers, some have 1, some have 3 etc.
Now I have to transfer the data to another database with a strict table structure and here the table that contains the user also should contain the users phone number and an alternative phone number, if the user currently has more than one phone number connected.
This means that if for instance we have three or more phone numbers connected to one user, we can maximum transfer two of them. This is not a big issue though...
We have ranked the importance of the phone numbers in the order as I presented them above.
What I do in my T-SQL query is to do a ISNULL() and see if the user has "Direct phone" connected, if not I check for the next type and so on.
Now to my problem! Can anyone give me a suggestion of how to write the code for the extraction of the Alternative phone? What I need to do is to check if there is a "Direct phone" connected to the user, if so I should NOT chose that but the next phone number that I find.
I'm currently developing an ASP.NET website which is using SQL Server 2005 and I couldn't decide between two table designs and I hope you can give me your opinions
The website is for a school and it'll be used to create tests from questions. The teacher will:
1. Select grade (could be multiple selection)
2. Select class
3. Select subject
The thing is that same question could be used for multiple grades.
Example query: "Get me questions of trigonometry of math from grades 7,8,9"
(Names used instead of ID's to make it more clear)
The first design:
[BigRelationsTable]
ID - QuestionID - GradeID - ClassID - SubjectID
1 - Question123 - Grade7 - Math - Trig
2 - Question123 - Grade8 - Math - Trig
3 - Question123 - Grade9 - Math - Trig
This is a simple design but all of the columns will need indexes because all of them will be used for searching and that makes me think about table performance.
Second design:
[GradeClassRelations]
ID - Grade - Class
1 - 7 - Math
2 - 8 - Math
3 - 9 - Math
[ClassSubjectRelations]
ID - GradeClassRelationsID - SubjectID
1 - GradeClassRelations1 - Trig
2 - GradeClassRelations2 - Trig
3 - GradeClassRelations3 - Trig
[SubjectQuestionRelations]
ID - ClassSubjectRelationsID - QuestionID
1 - ClassSubjectRelations1 - 1
2 - ClassSubjectRelations2 - 1
3 - ClassSubjectRelations3 - 1
This one is more normalised but this time the need of doing multiple joins makes me wonder.
What do you think? Which one should I use? Or if you have any other suggestions I'm all ears

I have 4 columns and 3 rows. Columns are Name, Age, Gender and Weight. I have values entered for each column. I need to pick the highest value of weight if Name, Age, Gender are same and put that into new table. how can i do that?
Greetings SSIS friends
I want to implement the following query using SSIS Data flow Source component :
SELECT * FROM someTable WHERE someColumn = 'H'
How do I restrict the data coming from my data source? By that I mean how do I apply the WHERE clause in SSIS?! Should I use a conditional Split component?! but that would mean retrieving all records first then adding the split component (not the most efficient method surely).
Any suggestions would be much appreciated.
Hi there,
I have created an SSIS package which pushes data from SQL Server (2005) to Oracle (Version 9.2.0.7.0), but having some issues with setting up the connection objects to Oracle.
I have attempted the connection with both the OLE DB Destination connection in SSIS and also with an ODBC connection, but both come up with the same error "ORA-12154: TNS could not resolve service name".
I am using a 32-bit version of SQL Server 2005 and the Oracle DB is 64-bit. Any ideas?
Hi there,
There's a field with Varchar(5) type which contains both alpha and alpha-numeric data. When sorting based on this field 1001 comes before 101. Is there anyway I can sort it appropriately; is there any collation or something which could be used.
Result of the sort:
1001
101
102
1022
103

I want to choose a column dynamically depending on a session variable.
In other words, each customer has a different price level. so I need to choose the column that corresponds to thier price level in thier customer record
Any help is appreciated.
below is my futile attempt

<SelectParameters>
I want this...:
SELECT [DateEntered], [From], [To], [Company], [Catagory], [Client], [Description], [TotalHours] FROM [JcpowersJobs] WHERE ([From] > 5/20/2008 12:00:00 AM) AND ([To] < 5/21/2008 11:59:59 PM)
Obviously this won't work, but can anyone tell me what WOULD work?
I have to write a large data migration script to move data from one SQL Server database to another. Is there any way to dynamically specify the server and database name? I would like to do something like the following, (but this does not seem to work):
Delete From [@ServerName].[@ImportToDatabase].[MyTable]
Any help appreciated
Hi,
I'm helping a small company built a new website and intranet in asp.net 2.0 and SQL.
I'm having trouble choosing among vs.net 2005, vwd express, SQL 2005
express or SQL 2005 Developers Edition for the prototype/testing phase.
Any advice? I want to build production-ready versions with easy
migrations to production, but I don't want them to have to spend too
much $$$ while it's just in alpha and being prototyped.
thanks,

Hi,
I have a table with its ID field set as an Identity column with "seed" and "increment" set to 1. Now, I have rows in there that I don't want to change. I'd like the next addtitions to the table to start at a specific value for their ID columns.
Basically, how can I specify a new starting value for an identity column?
Thanks,

Hello all,
I got a problem when using Sql Service 2005. I have two parameters @ID and @Name. I want to choose either and only one parameter to generate my report at one time. Could anyone tell me how to do it? I tried the "or" tab after filter tab, but it only generate the report with both @ID and @name values I gave.
Thanks in advance.
Hi,
I need to be able to get the maximum value of different calculations.
Example :
i have 5 calculations like this :
(sum(Fields!CountTest1.Value)/sum(Fields!TestCount.Value))*100
(sum(Fields!CountTest2.Value)/sum(Fields!TestCount.Value))*100
(sum(Fields!CountTest3.Value)/sum(Fields!TestCount.Value))*100
(sum(Fields!CountTest4.Value)/sum(Fields!TestCount.Value))*100
(sum(Fields!CountTest5.Value)/sum(Fields!TestCount.Value))*100
these calculations give me a percentage from a test value against the total test values.
what function or expression can i use to get the max value of all the calculations ?
I was looking at the "choose" function but i'm not quite sure how...
anybody ? help ....

I have an ActiveX Script Task in SQL Server 2000. It chooses one of two
possible success-paths depending on if a file exist or not. (Part of the old ActiveX Script for choosing next step is below)
I need to rewrite this for a Script Task in SQL Server 2005 but it seems like it
doesn't have this functionality and objects.
Does anyone know how to write the code for choosing the next step in a
Script Task or knows another way to solve my problem?
The package is not suppose to fail if the file is missing, it's must succeed and that's why I need two success-paths.
Regards,
Sara

Hi there,
How to choose the right RAID level for a database server based on disk performance counters?
Lets say I have the collected performance counters data for Disk Transfers/sec, Disk Writes/sec and Disk Reads/sec.
Or is there any other best method to decide the RAID level?
Please let me know.

We have two tables (one has DTS import of external spreadsheet - the other is the online table)
The scenario is that I need to add items (from the first table) to the second table, when they don't exist. However, it's harder than that - the second table, in some fields has integers (ID field)), referring to another table (let's call it the 3rd table), but the first table has text (which is in the description, in the third table).
I have to run through the first table, row by row, checking the part number if it already exists in the second table - nothing happens, and it goes to the next line. In each line, if the part number does NOT exist, I need to insert the data in that row. BUT - remember that third table, for the item(s) in the first table with text, I need to dynamically query the third table, to get the ID, in order to complete the insert correctly (Select ID from Third Table where Description=@FirstTableFieldText)
I've never done anything like this, and I have no idea how to put this together - especially if it's all in one Stored Procedure. I need some help here on recommended ways to do it (and how)..... Even the base structure (pseudo code- whatever) would help
I've got a page with a SQLDataSource control successfully populating a Dropdownlist...
However, now I find I need extended functionality - so I've got another page with links to this page, using querystrings - I need to hit the page, check the querystring, and if it's blank, just continue, but if the querystring is populated, then choose that item. I've tried the page_load and the page_prerender, but so far, it's not working:CC = Request.QueryString("center")If CC <> "" Then' DropDownList1.Items.FindByText(CC).Selected = TrueDropDownList1.SelectedIndex = DropDownList1.Items.IndexOf(DropDownList1.Items.FindByText(CC))End if
I've double checked, and yes, every time CC is populated, that item is definitely in the dropdownlist - it just doesn't get changed to that item.
ideas?
End If
Hello everyone
I'm really new to Data Presentation Controls and I already hate them couse I think they are way too complicated. Becouse of that i have already met wall many times. My last one sounds like this.
I'm triing to put a default value from, lets say SqlDataSource1 in a DropDownList that is created by SqlDataSource2. I know how to get value from SqlDataSource1 but I don't know how to use exactly that value as my default value in DropDownList.
Two more question.
1. Is it possible to have two different select statements in a SqlDataSource?
2. A SqlDataSource may contain an insert statement, select statement, update and delete. If I bind this SqlDataSource to a control how can I specify which of those statements will be used?
Thanks in advance
I would like to understand the algorithm that the linear regression method uses to choose the regressors in the model from a list of possible regressors.
I think that it is different from the common methods used in statistics like stepwise, forward or backward.
