Names and Quoting
- Table and column names are considered identifier names; as such, they are restricted to the following characters: [A-Z, a-z, 0-9, _:@].
- To use a table or column name with characters not listed above, the name must be quoted using square brackets ([name]) in any SQL statement.
- Parameter names can optionally start with the @ symbol (e.g., @p1 or @CustomerName) and cannot be quoted.
- Strings must be quoted using single quotes (e.g., 'John Doe').
