## com.trolltech.qt.sql
Class QSqlError

    java.lang.Object
      com.trolltech.qt.internal.QSignalEmitterInternal
          com.trolltech.qt.QSignalEmitter
              com.trolltech.qt.QtJambiObject

All Implemented Interfaces:
  QtJambiInterface, java.lang.Cloneable

    public class QSqlError

extends QtJambiObject
implements java.lang.Cloneable

The QSqlError class provides SQL database error information. A QSqlError object can provide database-specific error data, including the `driverText()` and `databaseText()` messages (or both concatenated together as `text()`), and the error `number()` and `type()`. The functions all have setters so that you can create and return QSqlError objects from your own classes, for example from your own SQL drivers.

See also:
  `QSqlDatabase::lastError()`, and `QSqlQuery::lastError()`.

Nested Class Summary
`static class` | `QSqlError.ErrorType` This enum type describes the context in which the error occurred, e.g., a connection error, a statement error, etc.
