Body
When working with lists a all elements are often of similar datatype or meaning. You seldom see lists like <code>["John Doe","1970-01-01","London"]</code> but rather <code>#person{name="John Doe",...}</code> or even {"John Doe",...}. To change a value in a record and tuple: <pre><code>-record(person,{name,born,city}). f(#person{}=P) -> P#person{city="New City"}. % record f({_,_,_,}=Tuple) -> erlang:setelement(3,Tuple,"New City"). % tuple </code></pre> This might not solve anything for your particular problem. To take your own example in comment: <pre><code>f1([H1,H2,_H3,H4,H5],E) -> [H1,H2,E,H4,H5]. </code></pre> If you give a more specific description of the environment and problem it's easier to under which solution might work the best. Edit: One (rather bad) solution 1. <pre><code>replacenth(L,Index,NewValue) -> {L1,[_|L2]} = lists:split(Index-1,L), L1++[NewValue|L2]. 1> replacenth([1,2,3,4,5],3,foo). [1,2,foo,4,5] </code></pre> Or slightly more efficient depending on the length of your lists. <pre><code>replacenth(Index,Value,List) -> replacenth(Index-1,Value,List,[],0). replacenth(ReplaceIndex,Value,[_|List],Acc,ReplaceIndex) -> lists:reverse(Acc)++[Value|List]; replacenth(ReplaceIndex,Value,[V|List],Acc,Index) -> replacenth(ReplaceIndex,Value,List,[V|Acc],Index+1). </code></pre> Even better is my function f1 above but maybe, just maybe the problem is still located as discussed above or <a href="https://stackoverflow.com/questions/4370756/replace-an-element-at-an-index-in-a-list-in-erlang">here</a>.

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.
