I have table value parameter @tvpMyKeys.I am filling it through a select statement.
After filling it I have to loop through each entry of my table value parameter tvpMyKeys and perform some deletion.
How can I loop through all records of a table value parameter

You can delete from a table with joining @tvpMyKeys.
Think set based!

Something like this but you have to work out what to do in case of error / rollback and so on...


while exists(select * from @YourTablevar)
begin
  begin transaction
  set @MyID = (select top 1 @YourTablevar.Column from @YourTablevar)
  delete from table1 where id=@MyID
  ...
  commit transaction
  delete from @YourTablevar where @YourTablevar.Column = @MyID
end
