# TParam.Bound

Is the parameter value bound (set to fixed value)

## Declaration

Source position: db.pas line 1758

`public property TParam.Bound: Boolean read FBound write FBound;`

## Description

Bound indicates whether a parameter has received a fixed value: setting the parameter value will set Bound to True. When creating master-detail relationships, parameters with their Bound property set to True will not receive a value from the master dataset: their value will be kept. Only parameters where Bound is False will receive a new value from the master dataset.
