Hi Raghu,

No, You doens't loose your persistant data. If you need to purge your data too, you need to create a trigger or implement callback  method %OnDelete.

Using Triggers - Using InterSystems SQL - InterSystems IRIS Data Platform 2021.1
Defining Callback Methods - Defining and Using Classes - InterSystems IRIS Data Platform 2021.1
