Please help as it is on priority.
Hi @borahmridul Welcome to the community
Just to clarify, this is a community forum staffed by volunteers; there is no priority. Every question is of equal importance, and there is no SLA for response time or even a response.
That said we would like to help, but you have not provided enough information
You will need to provide sample data, sample code/query and the desired result, and then perhaps someone will be able to help
