How to change dataset QUERY connection string at runtime in

Question

Hi,

I've a dataset called MyDataSet.XSD. I want to access this in code behind and assign different connection strings based on user logs in.

I've TableAdapters and Queries configured to it.

I access Adapters like below:
objDa.Connection.ConnectionString="myConString";

How assign to Query in dataset dynamically in asp.net?
