Looking at the log seems like MS Access doesn't support prepared statements.

Re: ANN: clojure.java.jdbc 0.0.7
Hi, Don't disagree about MS Access but it's a useful simple tool some times... The code is: (defn get-target [bu measure year] (with-connection db (with-query-results rs ["Select Period_Month, Target From Targets_Qry Where BU_ID = ? And Measure_Code = ? And Period_Year = ?" bu measure year] (to-dataset (into [] rs) It worked fine with clojure 1.2 and clojure.contrib.sql Thanks, Andrew -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Spread work onto multiple threads (in pure Clojure)
Fail enough. I guess, to allow nested spawning and avoid deadlocks, tasks should finish without waiting for the result but spawn a new task similar to itself that would check for the completion of the child tasks, repeating the cycle if necessary. Imagine that task t1 is monitored through a future f1, now it spawns child task t2 which is monitored through a future f2. t1 doesn't wait for t2 to complete, but reschedules a new task t3 that would check f2 for completion, and if f2 is done then sets f1 to done, otherwise reschedules itself as t4. Although I don't know how memory hungry it may get and what would be the impact on the length of the task queue. Maybe we could make the queue of limited length and if new task t2 gets rejected then it is performed within the task t1? Cheers, Ivan.

If 48 cores each start 48 threads, each of those threads start another 48 etc., it doesn't take long before you have enough threads to bog down even the most powerful server. But what would be the purpose of a nested "run this on all cores" construct? You are already running on all cores, there are no spare resources, so in terms of CPU time I can't see how it would differ from merely having the pmapped function use a plain same-thread map? There are no particular advantages to pmap-pool over pmapall that I can see, except that pmap-pool lets you control the number of threads more easily. (E.g. for debugging "where does it stop scaling linearly" problems.) I thought creating thousands of agents (as pmapall does) would be more expensive, so I tried an alternative, but in practice they seem to be equally fast; at least on this test and the kind of hardware I have access to. So pmapall wins by having fewer lines of code.

Re: ClojureScript: integration with jQuery
ClojureScript can access globals via js/foo. You can easily interact with your existing codebase using this simple feature. For example: (ns foo.bar) (def j js/jQuery) (.text (j "div#foo") "jQuery works!") Were you looking for something more sophisticated then this?

newbie, installation problem
I'm trying to install Clojure following the directions at http://riddell.us/ClojureSwankLeiningenWithEmacsOnLinux.html . I'm installing on SimplyMepis.

clojure struct with java
Hi guys,
I’m trying to call Clojure from Java(I already managed to do it
compiling Clojure using :gen-class ).
I want call Clojure using Java without compiling Clojure… I’m having
issues with my structs they are not behaving in the way that I want, I
tested the Clojure code on REPL and it seems to be ok...
I Guess is something that I’m doing in java(possibly wrong )
[company.clj]
(ns user)
(def employees (ref []))
(defstruct employee :name :age :role :salary)
(defn hire[e]
(dosync (alter employees conj e))
)
(defn print-employee[e]
(prn (str "Name: " (:name e) " - Age: " (:age e)
" - Role: " (:role e) " - Salary:" (:salary e)
)
)
)
(defn print-employees[]
(for [i (range (count @employees))]
(print-employee (employees i))
)
)
[JavaCallsClojureInterpreted.java]
import clojure.lang.RT;
import clojure.lang.Var;
/**
*
* @author Diego Pacheco
*
*/
public class JavaCallsClojureInterpreted {
public static void main(String args[]) throws
Throwable{
try{
RT.loadResourceScript("company.clj");
Var struct = RT.var("clojure.core",
"struct","employee :diego 10 :coach 1000");
Var hire = RT.var("user", "hire");
Object r = hire.invoke(struct);
System.out.println(r);
Var printee = RT.var("user", "print-employee");
Object r2 = printee.invoke(struct);
System.out.println(r2);
Var print = RT.var("user", "print-employees");
Object result = print.invoke();
System.out.println(result);
}catch(Exception e){
e.printStackTrace();
}
}
}
This code produce the following output:
[#'clojure.core/struct]
"Name: - Age: - Role: - Salary:"
null
"Name: - Age: - Role: - Salary:"
clojure.lang.LazySeq@1f
Any Clue ?
Thanks for your help.
Cheers,
Diego Pacheco

A question about lazy-seq fn.
Hi, Most of the examples I see about using the lazy-seq fn. make use of cons to build the list (or a seq). Can we not use lazy-seq with a conj? And why? If it possible to use lazy-seq with a conj, then an example would be great. Thanks, Manoj. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Basic Question on Record construction
Hi all, this may be a very simple question but I have not been able to find any docs that help me (defrecord R [a b c]) Is there something equivalent to: (def r (apply R. ["a" "b" "c"])) available? (without writing macros?) (in practice the list would be generated by some other function - say splitting a string or mapping over something else) Thanks Dave -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: clojure struct with java
I suspect this...
Var struct = RT.var("clojure.core", "struct","employee :diego 10 :coach
1000");
isn't doing what you think it will. That will set the root binding of
clojure.core/struct to the string you gave it. you probably want to get the
var for the struct function, and then invoke it with the arguments to create
an employee struct instance.
