What is the default join strategy in Teradata???

Answer Posted / tdguy

i think there is no "default" join strategy. Optimizer
decides the type of strategy based on the best retrieval
path and other parameters to execute the query. Merge join
strategy, nested join strategy, hash join strategy and
product join strategies are the common strategies followed
by TD.
