Documentación de las funciones miembro

bool QSQLiteDriver::beginTransaction

(

)

[virtual]

Protected function which derived classes can reimplement to begin a transaction. If successful, return TRUE, otherwise return FALSE. The default implementation returns FALSE.

Ver también:

commitTransaction(), rollbackTransaction()

Reimplementado de QSqlDriver.

void QSQLiteDriver::close

(

void

)

[virtual]

Derived classes must reimplement this abstract virtual function in order to close the database connection. Return TRUE on success, FALSE on failure.

setOpen()

Implementa QSqlDriver.

bool QSQLiteDriver::commitTransaction

(

)

[virtual]

Protected function which derived classes can reimplement to commit a transaction. If successful, return TRUE, otherwise return FALSE. The default implementation returns FALSE.

Ver también:

beginTransaction(), rollbackTransaction()

Reimplementado de QSqlDriver.

QSqlQuery QSQLiteDriver::createQuery

(

)

const [virtual]

Creates an empty SQL result on the database. Derived classes must reimplement this function and return a QSqlQuery object appropriate for their database to the caller.

Implementa QSqlDriver.

bool QSQLiteDriver::hasFeature

(

DriverFeature

f

)

const [virtual]

Returns TRUE if the driver supports feature f; otherwise returns FALSE.

Note that some databases need to be open() before this can be determined.

bool QSQLiteDriver::open	(	const QString &	db,
		const QString &	user,
		const QString &	password,
		const QString &	host,
		int	port,
		const QString &	connOpts
	)

Esta es una función miembro sobrecargada que se suministra por conveniencia. Difiere de la anterior función solamente en los argumentos que acepta. Open a database connection on database db, using user name user, password password, host host, port port and connection options connOpts.

Returns TRUE on success and FALSE on failure.

Ver también:

setOpen()

Reimplementado de QSqlDriver.

bool QSQLiteDriver::open	(	const QString &	db,
		const QString &	user,
		const QString &	password,
		const QString &	host,
		int	port
	)		[inline, virtual]

Derived classes must reimplement this abstract virtual function in order to open a database connection on database db, using user name user, password password, host host and port port.

The function must return TRUE on success and FALSE on failure.

QSqlIndex QSQLiteDriver::primaryIndex

(

const QString &

tableName

)

const [virtual]

Returns the primary index for table tableName. Returns an empty QSqlIndex if the table doesn't have a primary index. The default implementation returns an empty index.

Reimplementado de QSqlDriver.

QSqlRecord QSQLiteDriver::record

(

const QString &

tableName

)

const [virtual]

Returns a QSqlRecord populated with the names of the fields in table tableName. If no such table exists, an empty record is returned. The default implementation returns an empty record.

Reimplementado de QSqlDriver.

QSqlRecord QSQLiteDriver::record

(

const QSqlQuery &

query

)

const [virtual]

Esta es una función miembro sobrecargada que se suministra por conveniencia. Difiere de la anterior función solamente en los argumentos que acepta. Returns a QSqlRecord populated with the names of the fields in the SQL query. The default implementation returns an empty record.

Reimplementado de QSqlDriver.

QSqlRecordInfo QSQLiteDriver::recordInfo

(

const QString &

tablename

)

const [virtual]

Returns a QSqlRecordInfo object with meta data about the table tablename.

Reimplementado de QSqlDriver.

QSqlRecordInfo QSQLiteDriver::recordInfo

(

const QSqlQuery &

query

)

const [virtual]

Esta es una función miembro sobrecargada que se suministra por conveniencia. Difiere de la anterior función solamente en los argumentos que acepta. Returns a QSqlRecordInfo object with meta data for the QSqlQuery query. Note that this overloaded function may return less information than the recordInfo() function which takes the name of a table as parameter.

Reimplementado de QSqlDriver.

bool QSQLiteDriver::rollbackTransaction

(

)

[virtual]

Protected function which derived classes can reimplement to rollback a transaction. If successful, return TRUE, otherwise return FALSE. The default implementation returns FALSE.

Ver también:

beginTransaction(), commitTransaction()

Reimplementado de QSqlDriver.

QStringList QSQLiteDriver::tables

(

const QString &

tableType

)

const [virtual]

Returns a list of tables in the database. The default implementation returns an empty list.

The tableType argument describes what types of tables should be returned. Due to binary compatibility, the string contains the value of the enum QSql::TableTypes as text. An empty string should be treated as QSql::Tables for downward compatibility.
