<h3 class="fn"><a name="toString"></a><span class="type"><a href="qstring.html">QString</a></span> QSqlIndex::<span class="name">toString</span> ( const <span class="type"><a href="qstring.html">QString</a></span> & <i>prefix</i> = QString(), const <span class="type"><a href="qstring.html">QString</a></span> & <i>sep</i> = QLatin1String( "," ), <span class="type">bool</span> <i>verbose</i> = true ) const</h3>
<p>Returns a comma-separated list of all the index's field names as a string. This string is suitable, for example, for generating a SQL SELECT statement. Only generated fields are included in the list (see <a href="qsqlrecord.html#isGenerated">isGenerated</a>()). If a <i>prefix</i> is specified, e.g. a table name, it is prepended before all field names in the form:</p>
<p>"<i>prefix</i>.<fieldname>"</p>
<p>If <i>sep</i> is specified, each field is separated by <i>sep</i>. If <i>verbose</i> is true (the default), each field contains a suffix indicating an ASCending or DESCending sort order.</p>

<!-- $$$toStringList[overload1]$$$toStringListconstQString&bool -->
<h3 class="fn"><a name="toStringList"></a><span class="type"><a href="qstringlist.html">QStringList</a></span> QSqlIndex::<span class="name">toStringList</span> ( const <span class="type"><a href="qstring.html">QString</a></span> & <i>prefix</i> = QString(), <span class="type">bool</span> <i>verbose</i> = true ) const</h3>
<p>Returns a list of all the index's field names. Only generated fields are included in the list (see <a href="qsqlrecord.html#isGenerated">isGenerated</a>()). If a <i>prefix</i> is specified, e.g. a table name, all fields are prefixed in the form:</p>
<p>"<i>prefix</i>.<fieldname>"</p>
<p>If <i>verbose</i> is true (the default), each field contains a suffix indicating an ASCending or DESCending sort order.</p>
<p>Note that if you want to iterate over the list, you should iterate over a copy, e.g.</p>
<pre class="cpp"> <span class="type"><a href="qstringlist.html">QStringList</a></span> list <span class="operator">=</span> myIndex<span class="operator">.</span>toStringList();
<span class="type"><a href="qstringlist.html">QStringList</a></span><span class="operator">::</span>Iterator it <span class="operator">=</span> list<span class="operator">.</span>begin();
<span class="keyword">while</span>(it <span class="operator">!</span><span class="operator">=</span> list<span class="operator">.</span>end()) {
myProcessing(<span class="operator">*</span>it);
<span class="operator">+</span><span class="operator">+</span>it;
}</pre>
