    <p>Clojure question</p> <p>I have written the following function in clojure: In the first loop it iterates a list of maps and creates a map. Then the second loop iterates a list, matches data from the map previously created and a vector and returns a new map. However, different runs with the same data produce diffenet results. See below.</p> <pre><code>(defn resolve-case-per-period "Constructs a map by matching data existing in input parameter vectors" [dd case-details periods] (let [cases ((fn [in] (loop [case-details in, result-map {}] (if (= (count case-details) 0) result-map (recur (rest case-details) (assoc result-map (:priority (first case-details)) (:caseid (first case-details))))))) case-details) periods periods] (info "Mapping cases to periods step 1 completed " cases) (loop [periods periods, result-map {}] (if (= (count periods) 0) result-map (recur (rest periods) (conj result-map { (str (:period (first periods))) (get cases (:priority (first periods)))})))))) </code></pre> <p>The returned output is of a map like the following:</p> <pre><code>{31-10-10 20 10020101030122036M, 31-10-10 10 10020101030122036M, 31-10-10 21 10020101030122036M, 30-10-10 21 10020101030200157M, 31-10-10 00 10020101030122036M, 31-10-10 11 10020101030122036M, 31-10-10 22 10020101031112152M, 30-10-10 22 10020101030122036M, 31-10-10 01 10020101030122036M, 31-10-10 12 10020101030122036M, 30-10-10 23 10020101030122036M, 31-10-10 02 10020101030122036M, 31-10-10 13 10020101030122036M, 31-10-10 03 10020101030122036M, 31-10-10 14 10020101030122036M, 31-10-10 04 10020101030122036M, 31-10-10 15 10020101030122036M, 31-10-10 05 10020101030122036M, 31-10-10 16 10020101030122036M, 31-10-10 06 10020101030122036M, 31-10-10 17 10020101030122036M, 31-10-10 07 10020101030122036M, 31-10-10 18 10020101030122036M, 31-10-10 08 10020101030122036M, 31-10-10 19 10020101030122036M, 31-10-10 09 10020101030122036M} </code></pre> <p>Executing the function with the same parameters sometimes yields</p> <pre><code>{31-10-10 20 nil, 31-10-10 10 nil, 31-10-10 21 nil, 30-10-10 21 nil, 31-10-10 00 nil, 31-10-10 11 nil, 31-10-10 22 nil, 30-10-10 22 nil, 31-10-10 01 nil, 31-10-10 12 nil, 30-10-10 23 nil, 31-10-10 02 nil, 31-10-10 13 nil, 31-10-10 03 nil, 31-10-10 14 nil, 31-10-10 04 nil, 31-10-10 15 nil, 31-10-10 05 nil, 31-10-10 16 nil, 31-10-10 06 nil, 31-10-10 17 nil, 31-10-10 07 nil, 31-10-10 18 nil, 31-10-10 08 nil, 31-10-10 19 nil, 31-10-10 09 nil} </code></pre>

    1. CODon't be discuraged if you are getting some tough love in the answers, Clojure is different from more procedural languages, so it can be harder to get going. But there are good reasons for the differences and I am sure you will see the benefits if you stick with it a little bit.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
