Re: [Virtuoso-users] iSQL and "he statement has grown too long..."

2009-11-23 Thread Aldo Bucchi
Nevermind I answered this very dumb question by myself. The error actually prints the default limit bytes ( around 250k ), so you can take it from there. Now, please rephrase this: "Specifies that large command buffer to be used" --> "Specifies the size of the command buffer to be used" (http://do
