   • Programming language to write logic for SQL Server

     Top Answer

     Answered May 17, 2019 · 0 votes

     Essentially any logic that happens in a C# or Python program will be sent back to the data layer, simplistically, using SQL queries. For some more complex processing or buisness logic it may be preferable to push this logic up to the business logic layer away from the data layer.

     Making changes to SQL is easier that code as in the case of C# or Python a new version with updates to logic etc will require a new version of the software to be shipped. Whereas a DB change can happen behind the scenes.

     It depends entirely on what you want to acheive.

   • Difference between NULL in SQL and null in programming languages

     Top Answer

     Answered Jun 20, 2020 · 3 votes

     In SQL, we're interested in storing facts in tables (a.k.a relations).

     What Codd asked for was:

     Rule 3: Systematic treatment of null values:

     The DBMS must allow each field to remain null (or empty). Specifically, it must support a representation of "missing information and inapplicable information" that is systematic, distinct from all regular values (for example, "distinct from zero or any other number", in the case of numeric values), and independent of data type. It is also implied that such representations must be manipulated by the DBMS in a systematic way.

     What we've ended up with is three-valued logic (as @zmbq stated). Why is it this way?

     We have two items that we're trying to compare for equality. Are they equal? Well, it turns out that we don't (yet) know what item 1 is, and we don't (yet) know what item 2 is (both are NULL). They might be equal. They might be unequal. It would be equally wrong to answer the equality comparison with either TRUE or FALSE. So we answer UNKNOWN.

     In other languages, null is usually used with pointers (or references in languages without pointers, but notably not C++), to indicate that the pointer does not, at this time, point to anything.

   • SQL Server multi-user from same computer?

     Top Answer

     Answered Feb 11, 2016 · 0 votes

     Is it possible for both users to Remote Desktop to the same server, log in under different user accounts, then run the application, opening the same physical database?

     Yes.

     I'm getting the message: [...] when the second user attempts to open the database.

     The error you are getting indicates that the second user logged in does not have permission to access the database. You can fix this by connecting to your SQL Server instance with SQL Server Management Studio and configuring the permissions appropriately. Remember that you will need to create

     • the login for the user (on global SQL Server level) as well as
     • the user in the database (on the database level).

     An extensive introduction to SQL Server security is out of scope here, but plenty of tutorials can be found on the Internet.
