what is problem here

You can't do that. Parameters are meant to send literal values (strings,
integers, dates, etc). Not executable statements (or pieces of them).
You can make the query: "Select * From MyTable WHERE MyCol like @dotnet.itags.org.val"
Then add a variable called "@dotnet.itags.org.val", and set its value to whatever you need it
to be.

You can adjust your query based on input. Just leave that condition out of
the whereclause.
