QSqlError::QSqlError(const QString &driverText = QString(), const QString &databaseText = QString(), ErrorType type = NoError, const QString &code = QString())

Constructs an error containing the driver error text driverText, the database-specific error text databaseText, the type type and the error code code.

QSqlError::QSqlError(const QSqlError &other)

Creates a copy of other.

QSqlError::~QSqlError()

Destroys the object and frees any allocated resources.

QString QSqlError::databaseText() const

Returns the text of the error as reported by the database. This may contain database-specific descriptions; it may be empty.

See also setDatabaseText(), driverText(), and text().

QString QSqlError::driverText() const

Returns the text of the error as reported by the driver. This may contain database-specific descriptions. It may also be empty.

See also setDriverText(), databaseText(), and text().

bool QSqlError::isValid() const

Returns true if an error is set, otherwise false.

Example:

QSqlQueryModel model;
model.setQuery("select * from myTable");
if (model.lastError().isValid())
    qDebug() << model.lastError();

See also type().

QString QSqlError::nativeErrorCode() const

Returns the database-specific error code, or an empty string if it cannot be determined.

QString QSqlError::text() const

This is a convenience function that returns databaseText() and driverText() concatenated into a single string.

See also driverText() and databaseText().

ErrorType QSqlError::type() const

Returns the error type, or -1 if the type cannot be determined.

See also setType().

bool QSqlError::operator!=(const QSqlError &other) const

Compare the other error's values to this error and returns true if it is not equal.

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

Assigns the other error's values to this error.

bool QSqlError::operator==(const QSqlError &other) const

Compare the other error's values to this error and returns true, if it equal.
