Detailed Description

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().

Member Enumeration Documentation

enum QtSql.QSqlError.ErrorType

This enum type describes the context in which the error occurred, e.g., a connection error, a statement error, etc.

Enumerator:

ConnectionError	Connection error.
NoError	No error occurred.
StatementError	SQL statement syntax error.
TransactionError	Transaction failed error.
UnknownError	Unknown error.

Creates a copy of other.

QtSql.QSqlError.QSqlError	(	string	driverText = "",
		string	databaseText = "",
		QSqlError.ErrorType	type = QSqlError.ErrorType.NoError,
		int	number = -1
	)

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

Member Function Documentation

virtual void QtSql.QSqlError.CreateProxy ( )

virtual

new void QtSql.QSqlError.Dispose

(

)

new bool QtSql.QSqlError.IsValid

(

)

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().

new string QtSql.QSqlError.Text

(

)

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

See also driverText() and databaseText().

Property Documentation

new string QtSql.QSqlError.DatabaseText

getset

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

Sets the database error text to the value of databaseText.

new string QtSql.QSqlError.DriverText

getset

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

Sets the driver error text to the value of driverText.

new int QtSql.QSqlError.Number

getset

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

Sets the database-specific error number to number.

virtual System.IntPtr QtSql.QSqlError.SmokeObject

getset

new QSqlError.ErrorType QtSql.QSqlError.Type

getset

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

Sets the error type to the value of type.
