Detailed Description

The QSqlIndex class provides functions to manipulate and describe database 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.

Constructor & Destructor Documentation

QSqlIndex::QSqlIndex	(	const QString &	cursorName = `QString()`,
		const QString &	name = `QString()`
	)

Constructs an empty index using the cursor name of cursorname with an index of name.

QSqlIndex::QSqlIndex ( const QSqlIndex & other )

Constructs a copy of other.

QSqlIndex::~QSqlIndex ( )

Destroys the object and frees any allocated resources.

Method Documentation

void QSqlIndex::append ( const QSqlField & field )

Appends the field to the list of indexed fields. The field is appended with an ascending sort order.

void QSqlIndex::append	(	const QSqlField &	field,
		bool	desc
	)

Appends the field to the list of indexed fields. The field is appended with an ascending sort order, unless desc is true.

QString QSqlIndex::cursorName ( ) const

inline

Returns the name of the cursor which the index is associated with.

See also: setCursorName()

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

inline

Returns the name of the index.

See also: setName()

QSqlIndex & QSqlIndex::operator= ( const QSqlIndex & other )

Sets the index equal to other.

void QSqlIndex::setCursorName ( const QString & cursorName )

Sets the name of the cursor that the index is associated with to cursorName.

See also: cursorName()

void QSqlIndex::setDescending	(	int	i,
		bool	desc
	)

If desc is true the field i is sorted in descending order. Otherwise, the field for i is sorted in ascending order. If the field does not exist, nothing happens.

See also: isDescending()

void QSqlIndex::setName ( const QString & name )

Sets the name of the index to name.

See also: name()
