write lock is compatiable with which type of lock?..

Answer / yuvaevergreen

Adding to above, teradata locks objects on first come first
serve basis. write locks are generally used for dmls like
insert,update,delete. select statement uses access lock.
exclusive locks are used for ddls like create,alter. Pseudo
lock is a concept by which teradata assigns one amp to take
care of locking the rows of the table in other amps. This
amp makes sure that other amps lock the table.
