A QSqlError object can provide database-specific error data, including the driverText() and databaseText() messages (or both concatenated together as text() ), and the nativeErrorCode() and type() .

class PySide6.QtSql.QSqlError(other)

PySide6.QtSql.QSqlError([driverText=””[, databaseText=””[, type=NoError[, errorCode=””]]]])

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 error code code.
