Thank you for your response. I am explaining my situation there is table A on which I have taken a row lock and the primary key of table A is related with table B as a foreign key so automatically I can not insert new row with that foreign key now the primary key of table B is used as foreign key in table C and insertion can be done on table C. I just want to lock table C also No insertion can be done on table C related to table B primary key.
