Generate railroad diagrams from Books Online
-
Hello All,
Have you ever wanted to generate railroad diagrams from the Books Online grammar? That is, convert
CREATE TABLE
[ database_name . [ schema_name ] . | schema_name . ] table_name
{ AS FILETABLE |
( { <column_definition> | <computed_column_definition>
|<column_set_definition> | [ <table_constraint> ] } [ ,...n ] } )
to
?
Well, now you can! Just go to http://www.colindaley.com/translator/. It's free as in free beer. Let me know what you think.

Sigh. Well, I suppose that this means that I have got past the DNS problem at least.
To be clear, do you mean "net nanny" as in http://www.netnanny.com?

If your program can do that, then I have to say "Nicely Done".
However, I guess I'm the resident stick in the mud, though. If you compare the size of the RR Diagram to the syntax, then the syntax wins, so far as I'm concerned. I also like to copy the syntax out of BOL and just delete what I don't need. Bottom line is, they sure are pretty but I find no practical use in RR Diagrams by themselves. If people would list the syntax and display the RR Diagram instead of just doing one or the other, THEN they'd have a system worth looking at.
--Jeff Moden
RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.
"Change is inevitable... change for the better is not".

If your program can do that, then I have to say "Nicely Done".There is no need to ask if it can do that. Just try it. http://www.colindaley.com/translator/.

It can *almost* do what you want. My program actually calls another website (Railroad Diagram Generator - http://bottlecaps.de/rr) by Gunther Rademacher. His program generates diagrams from an EBNF syntax defined by the W3C. My program converts the T-SQL syntax to the W3C syntax and sends it to the Railroad Diagram Generator. If you clear the option to "Suppress EBNF display", then the diagram includes the syntax. Unfortunately, it will be the W3C syntax, which, apart from being useless in an SSMS query window, is a little verbose because it lacks some syntactic sugar that is present in the BOL syntax.
Anyway, if you want text to paste in a query window, then go to BOL. If you want something that is easy to remember, then you can look at a diagram.
