    <p>I have header file. I want a map object added to one of the structures. So I included </p> <pre><code>#include&lt;map&gt; </code></pre> <p>and compiled the program (note I did not use map object I just included it) and I got the following error</p> <pre><code>/usr/include/c++/4.7/bits/stl_map.h:115:28: error: macro "value_compare" requires 2 arguments, but only 1 given /usr/include/c++/4.7/bits/stl_map.h:733:45: error: macro "value_compare" requires 2 arguments, but only 1 given In file included from /usr/include/c++/4.7/map:62:0, from ../optimizer_types.h:16, from ../main.cpp:20: /usr/include/c++/4.7/bits/stl_multimap.h:115:28: error: macro "value_compare" requires 2 arguments, but only 1 given /usr/include/c++/4.7/bits/stl_multimap.h:656:45: error: macro "value_compare" requires 2 arguments, but only 1 given In file included from /usr/include/c++/4.7/map:61:0, from ../optimizer_types.h:16, from ../main.cpp:20: /usr/include/c++/4.7/bits/stl_map.h:113:11: error: invalid use of non-static data member 'std::map&lt;_Key, _Tp, _Compare, _Alloc&gt;::value_compare::comp' /usr/include/c++/4.7/bits/stl_map.h:116:4: error: from this location /usr/include/c++/4.7/bits/stl_map.h:116:9: error: '__c' was not declared in this scope /usr/include/c++/4.7/bits/stl_map.h:116:12: error: a function call cannot appear in a constant-expression /usr/include/c++/4.7/bits/stl_map.h:116:12: error: expected ';' at end of member declaration /usr/include/c++/4.7/bits/stl_map.h:116:14: error: expected unqualified-id before '{' token /usr/include/c++/4.7/bits/stl_map.h: In member function 'std::map&lt;_Key, _Tp, _Compare, _Alloc&gt;::value_compare std::map&lt;_Key, _Tp, _Compare, _Alloc&gt;::value_comp() const': /usr/include/c++/4.7/bits/stl_map.h:733:46: error: expected primary-expression before ';' token In file included from /usr/include/c++/4.7/map:62:0, from ../optimizer_types.h:16, from ../main.cpp:20: /usr/include/c++/4.7/bits/stl_multimap.h: At global scope: /usr/include/c++/4.7/bits/stl_multimap.h:113:11: error: invalid use of non-static data member 'std::multimap&lt;_Key, _Tp, _Compare, _Alloc&gt;::value_compare::comp' /usr/include/c++/4.7/bits/stl_multimap.h:116:4: error: from this location /usr/include/c++/4.7/bits/stl_multimap.h:116:9: error: '__c' was not declared in this scope /usr/include/c++/4.7/bits/stl_multimap.h:116:12: error: a function call cannot appear in a constant-expression /usr/include/c++/4.7/bits/stl_multimap.h:116:12: error: expected ';' at end of member declaration /usr/include/c++/4.7/bits/stl_multimap.h:116:14: error: expected unqualified-id before '{' token /usr/include/c++/4.7/bits/stl_multimap.h: In member function 'std::multimap&lt;_Key, _Tp, _Compare, _Alloc&gt;::value_compare std::multimap&lt;_Key, _Tp, _Compare, _Alloc&gt;::value_comp() const': /usr/include/c++/4.7/bits/stl_multimap.h:656:46: error: expected primary-expression before ';' token </code></pre> <p>As an experiment I moved the include to a cpp file and it was compiling properly.</p> <p>What could be the reason</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
