The QSqlRecordInfo class encapsulates a set of database field meta data.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> This class is a <a href="qvaluelist.html">QValueList</a> that holds a set of database field meta
|
||
|
|
data. Use <a href="#contains">contains</a>() to see if a given field name exists in the
|
||
|
|
record, and use <a href="#find">find</a>() to get a <a href="qsqlfieldinfo.html">QSqlFieldInfo</a> record for a named
|
||
|
|
field.
|
||
|
|
<p> <p>See also <a href="qvaluelist.html">QValueList</a>, <a href="qsqlfieldinfo.html">QSqlFieldInfo</a>, and <a href="database.html">Database Classes</a>.
