(inherits enum.Flag

Description
QSql.In
The bind parameter is used to put data into the database.
QSql.Out
The bind parameter is used to receive data from the database.

- PySide6.QtSql.QSql.NumericalPrecisionPolicy#
Numerical values in a database can have precisions greater than their corresponding C++ types. This enum lists the policies for representing such values in the application.
Constant
Description
QSql.LowPrecisionInt32
Force 32bit integer values. In case of floating point numbers, the fractional part is silently discarded.
QSql.LowPrecisionInt64
Force 64bit integer values. In case of floating point numbers, the fractional part is silently discarded.
QSql.LowPrecisionDouble
Force
double
values. This is the default policy.QSql.HighPrecision
Strings will be used to preserve precision.
Note: The actual behaviour if an overflow occurs is driver specific. The Oracle database just returns an error in this case.
