<P>
<p>The <a href="QSqlField.html#QSqlField(com.trolltech.qt.sql.QSqlField)"><tt>QSqlField</tt></a> class manipulates the fields in SQL database tables and views.</p>
<p><a href="QSqlField.html#QSqlField(com.trolltech.qt.sql.QSqlField)"><tt>QSqlField</tt></a> represents the characteristics of a single column in a database table or view, such as the data type and column name. A field also contains the value of the database column, which can be viewed or changed.</p>
<p>Field data values are stored as QVariants. Using an incompatible type is not permitted. For example:</p>
<pre> QSqlField field("age", QVariant::Int);
field.setValue(QPixmap()); <span class="comment">// WRONG</span></pre>
<p>However, the field will attempt to cast certain data types to the field data type where possible:</p>
<pre> QSqlField field("age", QVariant::Int);
field.setValue(QString("123")); <span class="comment">// casts QString to int</span></pre>
<p><a href="QSqlField.html#QSqlField(com.trolltech.qt.sql.QSqlField)"><tt>QSqlField</tt></a> objects are rarely created explicitly in application code. They are usually accessed indirectly through <a href="QSqlRecord.html"><tt>QSqlRecord</tt></a>s that already contain a list of fields. For example:</p>
<pre> QSqlQuery query;
...
QSqlRecord record = query.record();
QSqlField field = record.field("country");</pre>
<p>A <a href="QSqlField.html#QSqlField(com.trolltech.qt.sql.QSqlField)"><tt>QSqlField</tt></a> object can provide some meta-data about the field, for example, its <a href="QSqlField.html#name()"><tt>name</tt></a>, variant <a href="QSqlField.html#type()"><tt>type</tt></a>, <a href="QSqlField.html#length()"><tt>length</tt></a>, <a href="QSqlField.html#precision()"><tt>precision</tt></a>, <a href="QSqlField.html#defaultValue()"><tt>defaultValue</tt></a>, <a href="QSqlField.html#typeID()"><tt>typeID</tt></a>, and its <a href="QSqlField.html#requiredStatus()"><tt>requiredStatus</tt></a>, <a href="QSqlField.html#isGenerated()"><tt>isGenerated</tt></a> and <a href="QSqlField.html#isReadOnly()"><tt>isReadOnly</tt></a>. The field's data can be checked to see if it <a href="QSqlField.html#isNull()"><tt>isNull</tt></a>, and its <a href="QSqlField.html#value()"><tt>value</tt></a> retrieved. When editing the data can be set with <a href="QSqlField.html#setValue(java.lang.Object)"><tt>setValue</tt></a> or set to NULL with <a href="QSqlField.html#clear()"><tt>clear</tt></a>.</p>
