I want to generate a file that contains a stored procedure query and I want to share it, but I need to protect it from reading. This query will be used by another person in his own database and server.
I want to give a SP to another person to use in a different environment but doesn't want them to be able to read the TSQL in the SP.
How can I do that?
You can use the WITH ENCRYPTION clause. However, it is known to be ineffective and easily broken, and there are third party tools available that will let your client break it.
If you want to do it anyway, a tutorial can be found here.
If you use WITH ENCRYPTION along with a thoughtfully constructed EULA, your client should not accidentally see the code, and if he purposefully goes to the trouble to crack your code encryption, you will have civil recourse (i.e. you can sue them).

Program A is good at collecting data while Program B, in another language, is good at creating REST APIs. Is it possible to connect these two with a single database that A and B will read and write to? Performance for database operations is not really an issue in my case.
Sure this is possible. Databases typically can handle multiple connections from different programs/clients. A database does not really care which language the tool that is making the connection is written in.
Short edit:
Also most databases support "transactions". Which are used to cover that different connected clients do not break consistency of your application data while reading and writing in parallel.

I have two databases in two networks. I want to check one against another for to see table definition mismatches. I have database definition scripts of both databases. Is there any built-in function in SQL Server to achieve this.?
All the configurations in database servers are similar. The server version is SQL Server 12.0.2.
Update: I know there are text comparison tools, and I use beyond compare.
If you have the database definition scripts the easy way is to use diff on the UNIX (or Mac) command line, or windiff in Windows (see https://answers.microsoft.com/en-us/windows/forum/windows_10-files-winpc/does-windiff-exec-available-in-windows-10-64-bit/624fb262-7cba-49bd-b02e-74814a4d11b6?auth=1).
Otherwise you can use a database design tool. There are many available but they all cost a lot more than using diff.

I am deploying an application at one of our vendor. We have few special character that needs to be removed using a function. Vendor is really slow with any changes that we request.
I have access to one of the configuration table that we use to save configuration table.
I want to save a SQL function in the table column that I will fetch at run-time and will execute it.
I am not sure if its a good programming practice. Please suggest if this should not be used then why or is there any other way to do it?
Database is SQL Server. Suggest if it's a good programming practice.
A better practice would be to write your function in such a way that you don't have to change it every time a new special character pops up.
Instead of writing a function that filters out a predefined set of special characters, why don't you write a function that allows a predefined set of non-special characters? Then you should never have to change it.
you can use a Computed column in sql server, for me it's not a good practice depending on the scenario that you are trying to achieve but I think this might help you

Apologies in advance if this is a stupid question. I've more or less just started learning how to use SQL.
I'm making a website, the website stores main accounts, each having many sub-accounts associated with them. Each sub-account has a few thousand records in various tables associated with it.
My question is to do with the conventional usage of databases. Is it better to use a database per main account with everything associated with it stored in the same place, store everything in one database, or an amalgamation of both?
Some insight would be much appreciated.
Will you need to access more than one of these databases at the same time? If so put them all in one. You will not like the amount of effort and cost 'joining' them back together to do a query. On top of that, every database you have needs to be managed, and should you need to transfer data between them that can get painful as well.
Segregating data by database is a last resort.

I have a project to create an MS Access Database driven, VB application.
I need to use SQL coding, so cant just use the standard add data source.
The database would need to be able to have information accessed from the database as well as being able to add more data through the application.
Any help would be great.
Thanks
It seems as though you need a place to start looking, instead of what your question is asking. I'll provide a list.
Connecting to an MS Access Database (OleDb) See here
Referring to your connection string from the config file rather than inside each sub/function. If you have to recompile with a different connection string you only need to change it in one location.
Using SQL in VB.NET. See here.
Using SQL in VB.NET is looked down upon because it's essentially an "error-less" string. People use Linq for a lot of their database needs. That might be a little advanced at this stage in the game.
Take the time to become familiar with these procedures, and look up the documentation regarding OleDb class, parameterizing queries, etc.
