Ok, thanks. You seem to be right, but I got stuck halfway
unfortunately. One problem I have is understanding the
workings of slime, swank and sbcl. If I eval something
within an emacs buffer by M-C-x, where does that happen?
It doesn't influence the environment started with M-x slime,
right? I got confused about this. So the repl and the
evaluations are two separate things, I guess...
However I am not sure where the mentioned (C-c C-v i) should
go for instance. Sorry if I am slow, but I don't really grasp it
yet :-(.
I managed to to connect to my mysql database by executing
the clsql-tutorial.lisp file (from clsql/examples) with (load
#p"...").
However I during file evaluation I get an error after the connection
is established:
The value 0
is not of type
(OR (VECTOR CHARACTER) (VECTOR NIL) BASE-STRING SYMBOL
CHARACTER).
[Condition of type TYPE-ERROR]
Restarts:
0: [RETRY] Retry SLIME REPL evaluation request.
1: [ABORT] Return to SLIME's top level.
2: [TERMINATE-THREAD] Terminate this thread (#<THREAD "repl-thread"
RUNNING {AE730F9}>)
Backtrace:
0: (STRING-EQUAL "YES" 0)[:EXTERNAL]
1: ((SB-PCL::FAST-METHOD CLSQL-SYS::OUTPUT-SQL (CLSQL-SYS::SQL-
CREATE-TABLE T)) #<error printing object>)
2: (CLSQL-SYS::SQL-OUTPUT #<error printing object>)
3: ((SB-PCL::FAST-METHOD EXECUTE-COMMAND (CLSQL-SYS::%SQL-

4: ((SB-PCL::FAST-METHOD CLSQL-SYS::%INSTALL-CLASS (CLSQL-
SYS::STANDARD-DB-CLASS T)) ..)[:EXTERNAL]
5: (CREATE-VIEW-FROM-CLASS EMPLOYEE)[:EXTERNAL]
(...)
I have no idea where to find that in the code. How can I relate
the error to the content of the source file? I checked the sbcl
debugger docs, but couldn't find anything. Since number 5
mentions create-view-from-class, I inspected it with the
(M-.) you tought me, but it didn't show me anything I could
relate to the error.
Could you please help me out some more?
Thanks,
Felix
