It makes no difference, both are the same.

As said, from performance point of view, they are the same. However, since you didn't mention what database you're using, from syntax point of view there may be differences since not all of the databases understand both syntaxes.

we are using sql server 2008

SQL Server understands both the operators...no issue at all

First off get someone who has a better grasp of English to help you with your question b/c what you have written makes absolutely no sense (to me anyway).

what you are trying to say ????

This should be fairly simple, but I'm rather new to SSIS.
I want to copy data from one table to another. The column names are not the same, and in the target table I may need to expand some columns so I don't get truncation errors.
I'm not really sure what objects in SSIS to use.
Many thanks
Everything makes sense in someone's mind

If the copy operation is quite simple, try following:
- define a Data Flow task and open it
- using Source Assistant, define the source database
- using Destination Assistant, define the destination database
- configure the source table for OLE DB Source (double click it to open the confiiguration)
- do the same for OLE DB Destination
- if you need expressions, add a Derived Column
- configure the derived column; add necessary new derived columns, their expressions etc
- connect the source to the derived column
- connect the derived column to destination
- in OLE DB Destination configure the mappings
Hope this gets you started

I was thinking, can Microsoft SQL Server handle projects such as Facebook, Linkedin, etc? and if answer is Yes, then why they didn't go for it?
|
|
|
|
|
Don't quite understand the question. Those examples you gave are applications consisting of several different layers etc.
If you mean that could Sql Server serve as the back-end for the data, why not? Sql Server is capable of data distribution between several server, workload balancing, distributed transactions etc. so I see no direct reason why it couldn't handle the data.
|
|
|
|
|
It can handle the data and workload, its just that these online companies and startups (as they were) opted for the cheapest option (ie free) back when they started up, to minimise startup costs. They carry on using these systems as it will be too costly to migrate onto another platform.
Simple economics really..

Yes, from the economics point of view the situation is different. For example Oracle has quite good concept now when MySql can be used when starting up and when performance etc problems arise, you can migrate to Oracle with a bit less work than to other database flavors.

Services like Facebook etc. need to be massively parallel and fault tolerant, to get the same level of service from sql server would mean a heavy investment in licenses, also these sites are using unix servers and sql server is not supported on them.

The simple answer is, yes, SQL Server can handle the volume of data these sites catered for. The key thing to note about these sites, though, is that they tend to opt for NoSQL[^] databases - which is not what SQL Server is designed to do.
|

As said before, it's a financial decision. The Amaren[^] Nuclear Plant, and MacLaren[^] are using Sql Server. To be fair; they're doing something more complex than putting some html-pages in there

And I'm betting they have a serious investment in SQL Server licences. And they will almost certainly have had direct support from MS if they are pushing the edge of the tech. I know we were offered all sorts of incentives to use MS high volume framework including direct intervention from MS techs. Mind you the licences were $1m+.

Pretty sure most companies are more than willing to offer incentives and support for large contracts.
And if one goes with a non-paid solution then of course one had also be prepared to provide ones own support for all possible problems.

if sql server can handle NASDAQ[^] then it could handle anything any of us could throw at it.
Common sense is admitting there is cause and effect and that you can exert some control over what you understand.
