    <p>for my game im trying to accomplish the following array structure by C++ because the data come from an external source and should be available in a lua_script.</p> <p>The array structure should look like this: (The data are in a map, the map contains the name of the variable and a list of Pairs (Each pair is a key value pair considered to be one element in one subarray)...</p> <p>The data prepared in the map are complete and the structure is definetly okay. So basically I have</p> <pre><code>typedef std::map&lt;std::string, std::list&lt;std::pair&gt; &gt;; /\index(e.g: sword) /\ /\ || || || Pair: Contains two strings (key/value pair) || List of Pairs for each array </code></pre> <hr> <pre><code>items = { ["sword"] = {item_id = 1294, price = 500}, ["axe"] = {item_id = 1678, price = 200}, ["red gem"] = {item_id = 1679, price = 2000}, } </code></pre> <p>What I got so far now is:</p> <pre><code>for(ArrayMap::iterator it = this-&gt;npc-&gt;arrayMap.begin(); it != this-&gt;npc-&gt;arrayMap.end(); it++) { std::string arrayName = (*it).first; if((*it).second.size() &gt; 0) { lua_newtable(luaState); for(ArrayEntryList::iterator itt = (*it).second.begin(); itt != (*it).second.end(); itt++) { LuaScript::setField(luaState, (*itt).first.c_str(), (*itt).second.c_str()); } lua_setglobal(luaState, arrayName.c_str()); } } </code></pre> <p>But this will only generate the following structure:</p> <pre><code>(table) [item_id] = (string) 2000 [name] = (string) sword [price] = (string) 500 </code></pre> <p>The problem is that the table can ofcourse only contain each index once. Thatswhy I need something like "a table in a table", is that possible?</p> <p>Is there a way to achieve this? Im glad for any hints.</p>

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.
