You will run into problems here.
The problem arises with spaces in the name, since the following pattern:

...([\w\s]+)...

matches

delete my database

as well as

delete database

In this case I guess you don't get away without a parser (use the Regex for tokenizing, use the parser to detect all commands and translate the arguments where needed).

Any names without spaces get easily translated, though, e.g.:
C#
string pattern = @"(?:\[?([\w\$]+)\]?)?\.\[?([\w\$]+)\]?";


And if you have optional spaces around "[" and ".", the following a bit more complicted regex will do:
C#
...
string open = @"(?:\[\s*?)?";
string close = @"(?:\s*?\])?";
string ident = @"([\w\$]+)";
string prefix = @"(?:" + open + ident + close + @"\s*?)?";
string suffix = @"(?:" + open + ident + close + @")";
string pattern = prefix + @"\.\s*?" + suffix;
...
