Extracting SQL from Delphi code and DFMs

[David Schwartz 426]

We've got a ton of SQL queries embedded in a Delphi app that we've decided to move to the server where they belong. Around 700 or so of them.

 

Does anybody have any ideas about how to most easily extract the SQL from Delphi code that generates them at run-time with a bunch of string catenation before stuffing them into the .SQL.Text property, or even via repetitive SQL.Add(...) methods?

 

Also, what's the best way to extract them from SQL properties in DFMs where they're defined at design-time?

 

The "obvious" approach in my mind is to use some kind of editing, like regular expressions, to remove common syntactic sugar needed to manipulate a bunch of string constants used to build up a big string.

 

Another thought was to use some kind of scripter to actually process the Delphi code in a way that generates the strings dynamically, then grab them from the buffer that way. (ie., use a run-time interpreter to process limited lines of code that produce longer strings, rather than at run-time.)

 

Any ideas?

Idk if possible, how about a simple line by line parser/checker?

It's a breeze using Delphi-AST! Try it, you'll be up n running fast.

Developer Roman Yankovsky has an Abstract Syntax Tree Builder source code project called Delphi AST over on Github.
An abstract syntax tree represents a tree of the abstract syntactic structure of source code in languages like Object Pascal. 
What you can do with it is basically pass in some Object Pascal source code like a unit and it will turn it into an XML representation
of that unit which can be navigated using XPath and other methods

Could you, please, elaborate what "move to the server" means? Is the result just a simple .sql files, which will be run on a server?

[David Schwartz 426]

some are simple, some are quite complex. The thing is, right now they're embedded in Delphi code on the client side. We want to move them into the server as stored procs, funcs, and views, and then replace the code on the Delphi side with simple calls to those server-side objects, parameterized where needed.

 

(We're preparing to migrate from Oracle to PostgeSQL, and there are tools that can convert server-side assets automatically -- not 100%, but enough to be useful. However, they won't read the Delphi code! So we want to take this opportunity to extract all of this random business logic and other SQL CRUD code from the client side and move it over to the server where it belongs.)

I built my 'SQL-DFM' browser using DX. If you have DX i can send the sources. The AST part i OS. But it hardly matters, look at AST demo, 700 strings takes less than a, sec to scan. Then you can even output or rearrange the props in the DFM. Or as i did, collect all in a neat grid with search, filters, grouping, sorting... you essentially write you own "navigator" for specific properties.

They're scattered across a few hundred source files. It's probably worth taking a look. Do you want to post it here and I can grab it, then you can leave it or delete it later?

I'll think of sumthing during work hours tomorrow.

Hi Dany! I'm interested in your tool either. May be a case for "I made this" sub-forum?

I second that!

OK. Just went in to check on that little tool. 

 

Turns out i have used DevExpress and RTC 😞 DevExpress because i do not have to do anything but fill a grid and there's search, sorting, filtering, pinning and all else. The only function i added was a checkbox to show the full row-height for the statements or just one row.

RTC is because i'm familiar with its JSON classes. The RTC JSON classes can be replaced with something else.

 

I just want to make it clear that for a "I made this" sharing i'd have to at *least* 1) get rid of 3rd party 2) implement settings for paths, properties selection et.al. 3) consider using project files in stead of paths, 4) consider an exe or plugin for the IDE... the to-do list could grow exponentially.

 

Another thing that i dearly have to apologise for is the mention of Delphi-AST, i have no idea what i was on about. I used this brilliant project:

 

https://github.com/masonwheeler/DFMJSON

 

not Delphi-AST at all. Apologies. Really. I should not post so fast.

end.

Call RunCollect and get each component and property/ies back in the onFound procedure. The onSuccess and onErr is for the log.

The rtcXXX functions is used to parse and walk the JSON hierarchy. It's very similar to reading and processing XML. Just ask me what happens if it's unclear.

As you can see the real work is done by the DFMJSON project in the Dfm2JSON and dfm.toString functions.

 

Here are two screenshots:

 

...and...

 

 

but that is very need-specific. I.e. what do you want to do with it all.

@Dany Marmur Thanks! We have DevEx ... what's RTC?

[Guest]

@David Schwartz, RTC is here https://rtc.teppi.net/ but as i said - i only used its JSON parsing classes (value handling). You should be able to snappily change it to what comes with Delphi.

Since you have DX, here's the complete visual code. Now i have pasted the whole project 🙂

BTW - you noticed my DACs are IBO, you have to change names to whatever you use.

Thanks, I do appreciate this, although a zip file attachment would be a lot easier to work with 😉  That's a LOT of text to scroll through here.

 

I noticed that the DWS project has migrated to BitBucket. Is there anything to be aware of when using it?

Yes, but a zip with an executable, then i have to code settings for the different names, i simply do not have the time now 😞.

The three code-windows above is all the code except for the dpr! You can just copy paste it really.

 

This is what i have for DWScript: https://xxx@bitbucket.org/egrange/dwscript.git

This is the path to DWSJSON: https://github.com/masonwheeler/DFMJSON.git

 

I suppose if one had the time you could VCL-ify it, add persistence and settings and some more and you'll have a neat contribution to the community.

This was a very fast hack when i moved from my own dynamic SQL-repository to using DFMs. I missed the global searches i could do in my own repo.

 

HTH,

I don't need an executable. It's just that posting the sources here directly take up most of the page and distract from an otherwise useful discussion.

@David Schwartz, i see - til next time!

It's a breeze using Delphi-AST! Try it, you'll be up n running fast.

DelphiAST seems a bit unhappy with DFM files. Anything in particular we need to know?

[Guest]

@Bill Meyer, when i wrote the original post from my phone i confused DWSJSON and Delphi-AST. Scroll up, i have a lot of apologies for that 🙂

I used DWSJSON for this project. "Only" to parse the DFM into JSON. Again, my apologies.

[Bill Meyer 337]

@Dany Marmur No problem. I also found: https://github.com/ADUG/DFMJSON

I realise this is slightly late to the party but another possible way to possibly tackle this problem is to actually instantiate the modules containing queries and then iterate over the component collection of each form/module looking for the relevant query component types and then doing whatever you want with them. (E.g. serialise to file, write out parameters, etc.)  Obviously this approach has some caveats that might make it less desirable in some instances (not least dependency issues).  Still it should not be that hard to come up with a project that just includes everything referenced etc.)  Anyway just a thought.

Hi...

 

If you extracting the SQL from Sourcecode, then you can save it as Resource...a better handling for more then one DBMS. 

But i think, that the extraction of of the SQL is manually work.

 

! Advertising from me...

How about this? DIMOWA®SQL Creator ...at the Moment in German.

 

Advantages:

* SQL not in query or sourcecode

* SQL as file on the disk

* SQL can tested in your favored Editor

* SQL, if you want, encypted in the EXE

* Shows more DBMS  side by side  in the editor

...and so on.

If you use FireDAC, you can also use the FireDAC Monitor to capture everything that goes on, databasewise.
