QSqlError::QSqlError(const QString &driverText, const QString &databaseText, ErrorType type, int number)

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

int QSqlError::number() const

Returns the database-specific error number, or -1 if it cannot be determined.

Returns 0 if the error code is not an integer.

Warning: Some databases use alphanumeric error codes, which makes number() unreliable if such a database is used.

Use nativeErrorCode() instead

参见 setNumber() and nativeErrorCode().

void QSqlError::setDatabaseText(const QString &databaseText)

Sets the database error text to the value of databaseText.

Use QSqlError(const QString &driverText, const QString &databaseText, ErrorType type, int number) instead

参见 databaseText(), setDriverText(), and text().

void QSqlError::setDriverText(const QString &driverText)

Sets the driver error text to the value of driverText.

Use QSqlError(const QString &driverText, const QString &databaseText, ErrorType type, int number) instead

参见 driverText(), setDatabaseText(), and text().

void QSqlError::setNumber(int number)

Sets the database-specific error number to number.

Use QSqlError(const QString &driverText, const QString &databaseText, ErrorType type, int number) instead

参见 number().

void QSqlError::setType(ErrorType type)

Sets the error type to the value of type.

Use QSqlError(const QString &driverText, const QString &databaseText, ErrorType type, int number) instead

参见 type().
