I assume you are referring to the brackets around object names. If you've
included spaces or other special characters in table or column names then
these have to be wrapped in square brackets when referenced in a query of
code. You can avoid this by not including such characters when creating the
table definitions, e.g. instead of a column named [Last Name] use LastName or
Last_Name. Also avoid using terms such as Date or Name as a column name, as
the first is the name of a built in function, the second of a property; use
something more specific such as TransactionDate or CompanyName.
