DESCRIPTION
The QSqlIndex class provides functions to manipulate and describe
QSqlCursor and QSqlDatabase indexes.
This class is used to describe and manipulate QSqlCursor and
QSqlDatabase indexes. An index refers to a single table or view in a
database. Information about the fields that comprise the index can be
used to generate SQL statements, or to affect the behavior of a
QSqlCursor object.
Normally, QSqlIndex objects are created by QSqlDatabase or QSqlCursor.
See also Database Classes.
MEMBER FUNCTION DOCUMENTATIONQSqlIndex::QSqlIndex ( const QString & cursorname = QString::null, const
QString & name = QString::null )
Constructs an empty index using the cursor name cursorname and index
name name.
QSqlIndex::QSqlIndex ( const QSqlIndex & other )
Constructs a copy of other.
QSqlIndex::~QSqlIndex ()
Destroys the object and frees any allocated resources.
void QSqlIndex::append ( const QSqlField & field ) [virtual]
Appends the field field to the list of indexed fields. The field is
appended with an ascending sort order.
Reimplemented from QSqlRecord.
void QSqlIndex::append ( const QSqlField & field, bool desc ) [virtual]
This is an overloaded member function, provided for convenience. It
behaves essentially like the above function.
Appends the field field to the list of indexed fields. The field is
appended with an ascending sort order, unless desc is TRUE.
QString QSqlIndex::cursorName () const
Returns the name of the cursor which the index is associated with.
QSqlIndex QSqlIndex::fromStringList ( const QStringList & l, const QSqlCursor
* cursor ) [static]
Returns an index based on the field descriptions in l and the cursor
cursor. The field descriptions should be in the same format that
toStringList() produces, for example, a surname field in the people
table might be in one of these forms: "surname"," surname DESC" or
"people.surname ASC".
See also toStringList().
bool QSqlIndex::isDescending ( int i ) const
Returns TRUE if field i in the index is sorted in descending order;
otherwise returns FALSE.
QString QSqlIndex::name () const
Returns the name of the index.
QSqlIndex & QSqlIndex::operator= ( const QSqlIndex & other )
Sets the index equal to other.
void QSqlIndex::setCursorName ( const QString & cursorName ) [virtual]
Sets the name of the cursor that the index is associated with to
cursorName.
void QSqlIndex::setDescending ( int i, bool desc ) [virtual]
If desc is TRUE, field i is sorted in descending order. Otherwise,
field i is sorted in ascending order (the default). If the field does
not exist, nothing happens.
void QSqlIndex::setName ( const QString & name ) [virtual]
Sets the name of the index to name.
