Detailed Description

The PySide.QtSql.QSqlError class provides SQL database error information.

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

class PySide.QtSql.QSqlError(other)
class PySide.QtSql.QSqlError([driverText=""[, databaseText=""[, type=NoError[, number=-1]]]])
Parameters:

Creates a copy of other .

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

PySide.QtSql.QSqlError.ErrorType

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

Constant Description
QSqlError.NoError No error occurred.
QSqlError.ConnectionError Connection error.
QSqlError.StatementError SQL statement syntax error.
QSqlError.TransactionError Transaction failed error.
QSqlError.UnknownError Unknown error.
PySide.QtSql.QSqlError.databaseText()
Return type:unicode

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

PySide.QtSql.QSqlError.driverText()
Return type:unicode

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

PySide.QtSql.QSqlError.isValid()
Return type:PySide.QtCore.bool

Returns true if an error is set, otherwise false.

Example:

model = QSqlQueryModel()
model.setQuery("select * from myTable")
if model.lastError().isValid():
    print model.lastError()
PySide.QtSql.QSqlError.number()
Return type:PySide.QtCore.int

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

PySide.QtSql.QSqlError.setDatabaseText(databaseText)
Parameters:databaseText – unicode

Sets the database error text to the value of databaseText .

PySide.QtSql.QSqlError.setDriverText(driverText)
Parameters:driverText – unicode

Sets the driver error text to the value of driverText .

PySide.QtSql.QSqlError.setNumber(number)
Parameters:numberPySide.QtCore.int

Sets the database-specific error number to number .

PySide.QtSql.QSqlError.setType(type)
Parameters:typePySide.QtSql.QSqlError.ErrorType

Sets the error type to the value of type .

PySide.QtSql.QSqlError.text()
Return type:unicode

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

PySide.QtSql.QSqlError.type()
Return type:PySide.QtSql.QSqlError.ErrorType

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