Blackfish SQL

by john 8/28/2007 7:36:00 AM

Blackfish SQL is a new database from [CodeGear], written totally in managed code. It comes in 2 flavors, local and remote. The local version runs in process, so it makes for really easy deployment. For ASP.Net applications you just deploy the Blackfish assemblies and stick your database file in the App_Data directory.

For a dotnet developer writing stored procedures can be a bit of a problem, this is not the case with Blackfish since you can develop them in your dotnet language of choice, In my case thats Delphi. In the screen shot below I am in the debugger stepping through a stored procedure. I think this is extremely cool...

Compared to any DB native language, writing stored procedures this way looks a very tedious task - you have to declare and code everything.


In PL/SQL you would just write


PROCEDURE INSERT_BOOKMARK(ATITLE IN VARCHAR..., ABOOKMARK_ID OUT NUMBER)


IS


BEGIN


 INSERT INTO BOOKMARKS(BOOKMARK_ID, TITLE...


 VALUES(SEQ_BOOKMARKS.NEXTVAL, ATITLE...)


 RETURNING BOOKMAR_ID INTO ABOOKMARK_ID;


END;


and the PL/SQL compiler/engine will take care of parameters, types, assignments... one line of code against how many??? That's probably why almost noone writes Java stored procedures - I'll stay away from .NET ones and BlackFishes too - better to use an Oracle Express instance.

There probably is a method overload that lets you construct and assign a parameter in one line. Also, I think it is not so much about simple SP. It is the compfort of having .NET lib support creating queries and having logic all in the same place.


What would be even more interesting is if it is possible to construct a query in an Objectoriented  style.


Something like


Query q = new Query(DbSchema).Where(...).In(...)
