Hi andrei I do not know the status of OBDC but you should know that code on squeaksource is in general quite old. Have a look at Garage which is a kind of JBDC. https://github.com/pharo-rdbms/garage You should probably have a version available via the catalog Stef On Fri, Dec 22, 2017 at 2:43 PM, Andrei Stebakov <lispercat(a)gmail.com> wrote: > Hi Stef > > Gofer new > squeaksource: 'ODBC'; > package: 'ConfigurationOfODBC'; load. > (Smalltalk at: #ConfigurationOfODBC) load. > > When I execute the code above I got an exception doesNotUnderstand: > #selector in RBParser>>externalFunctionDeclaration.

Re: [Pharo-users] NeoCSVWriter: how to output an empty quoted field

by Sven Van Caekenberghe

Hi Joachim, nil fields normally write as 'empty quoted fields': String streamContents: [ :out | (NeoCSVWriter on: out) nextPut: #(nil nil nil) ]. => '"","",""' Is this not what you want/need ?

NeoCSVWriter: how to output an empty quoted field

by jtuchel＠objektfabrik.de

Hi, I need to write a number of empty quoted fields in a CSV export. The receiving application will complain about missing quotes for empty text fields... (don't ask, I've done all the eye rolling for you already) My frst attempt was: writer addConstantField: '""'. But this doesn't write the quotes - I really don't see why, but it's the case. Also, adding writer addObjectField: [:a| '""']. doesn't really work, because it will literally add the double quotes between single quotes... (???) Do I really have to implement some method that returns an empty String on my business objects and use: writer addQuotedField: #justAnEmptyString. ? Am I missing some switch to enable quotes for empty quoted fields? My version of NeoCSVWriter on VA Smalltalk is not actually a current one...

Hi Stef Gofer new squeaksource: 'ODBC'; package: 'ConfigurationOfODBC'; load. (Smalltalk at: #ConfigurationOfODBC) load. When I execute the code above I got an exception doesNotUnderstand: #selector in RBParser>>externalFunctionDeclaration. Looks like currentScope variable is not defined. Also if I install ODBC from the catalog it also fails.

If bigger than the allowed range then it follows the slower kind of variable/indexed object. Another possibility could be Floats. Can you check in your debug if you have a cluster (FLSmallIntegerCluster subclass ) with MANY numbers? Else, check with many floats.. I think it should be somehow related to that...
