And I thought that the 'anything' would catch it too, but it didn't on my machine, it crashed. Maybe it is just my machine, or system. What system are you using? Mike

One thing I noticed when playing with this, is that it allows for ',' and ';' characters. They are escaped in the output. I was planning on testing this tonight to see exactly what sorts of objects there are in the list. At the same time, this might require that there be two different methods of inputting the SQL to send to the server, as the version that Jamie has is expecting everything in "message" format, which assumes that ',' have to be reinserted when an SQL statement contains comma's.

GUIs and loadbang
by Hans-Christoph Steiner 14 Nov '07

14 Nov '07

So all of the Tk widgets that I am using save their own state while they are running, then I am planning on querying them when the savefn is called to save their state, and of course, do the opposite when opening. The big question for me is what to do is how to handle loadbanged messages which change that state (the Tk widgets aren't instantiated yet) and what to do with messages received when the object instantiated without a GUI representation. So... I guess I am looking for the über-clever hack that means I don't have to keep a parallel data structure in C space... .hc ------------------------------------------------------------------------ ---- If you are not part of the solution, you are part of the problem.

Have you tried to use this with your 'psql'? It looks very interesting, although, it does not output as if it were a message. Basically, when I typed in some text... select id, name from mytable where x = 2; and it output a list as list select id\\, name from mytable where x = 2\\\; yes, the escape characters are there, and there is a comma... Just a thought. I will try this at home tonight on my stuff... Thank, Mike -- Help the Environment, Plant a Bush back in Texas!

BUT, the float method was just used for debugging, and should be taken out. If you look at the bottom of the source file, psql_float() doesn't actually get added to the class's methods. So, the external does the 'right thing' forwarding the ,1, as part of the query. BTW, '1' is not a valid column name (neither are names starting with a number), at least not in Postgres. Jamie

savefn + callback
by Hans-Christoph Steiner 14 Nov '07

14 Nov '07

Ok, now I am stymied... I am trying to make the savefn in tkwidgets get the state from the Tk widgets themselves. But I can't think of a way to do that with the standard pd_bind() callback mechanism. If there was a way to bind a "presave" function somehow... Any ideas? .hc ------------------------------------------------------------------------ ---- I spent 33 years and four months in active military service and during that period I spent most of my time as a high class muscle man for Big Business, for Wall Street and the bankers. - General Smedley Butler

At the same time, the process of building the message to create the SQL that then gets submitted could be cumbersome. If it is just a simple thing like loading up a textfile, and then forwarding this on that is one thing (assuming that each line in the textfile is a complete SQL statement), but to construct dynamic SQL on the fly, that is a whole different thing. And this doesn't even address the different types of SQL statements, each returning a different result set, or error code. And then there is still the issue of having to parse through the result sets as they comeback... > > > list would basically be UNFORMATTED data, and it would require the PD > > > code to interpret the result sets. > > KISS.

Ok, can anyone create a PD patch that might illustrate some of the ways you envision sending SQL to the database? Nothing "workable", just a prototype of what you see... While I would tend to agree in keeping it simple. There are a couple of hurdles that must be crossed. On the one hand, I get the impression that some are thinking that it is as simple as saying "select * from my-table;" and then you are done, each SQL statement is potentially VASTLY different from the next, and to expect to create a single INSTANCE of a connection, and pipe all your requests through that one object, I think is a little naive. If you are familiar with other Database programming enviornments, they assume that you are working with a single SQL statement (or a simple variable statement) that serves a single purpose. They don't (AFAIK) try to pipe all their requests through the same object. Working with SQL not only requires knowing the programming, but also the format of the data expected in the database. On the other hand, I would think that expecting a single object to handle this would result in a 'route'ing nightmare in the PD code in interpreting the result sets. While dealing with a single instance of an SQL statement that has known results, would be very manageable and not require a lot of routing.

My only comment is that it is a couple pixels off on Mac OS X 10.4/Pd-extended 0.39.2-test5. I can cover about 3 pixels before the scrollbars kick in.
