1. common is not possible, because the tables must be known at compile-time by the server, but you can do a stored-procedure for each table anbd change the name of the storedprocedure in your tstoredproc-object (if you use this)

2. the sql-server takes care of multiuser-access, no need to do something special (excepts your grants and userlogins)

Instead of stored procedure you can use Query and you can build it at run time such as:

ibQuery1.SQL.Text:= 'select * from ' + Edit1.Text;

SQL server takes care of multiusers
but when we are running two application and two users are trying to modify the same record or when one user is modifying a record while some other user is deleting that record. Those kind of errors how to handle those.

one user may have no luck and will get an exception thrown by the server forwarded through the connection-protocol to your application

SQL server takes care of multiusers,
doesn't matter if there are more users and/or applications accesses the same record, SQL server knows this, because all must go through the server

well there is a transaction issue,
depending on how you connect to the server (ado,bde,..).
but the default settings are normally useable.
