TD Lock Upgrade and Downgrade Options - forum topic by Santanu84

Hi
In a script, at Session level the transaction isolation is set to RU (Read Uncommitted or ACCESS).
At table level I am overriding to READ lock for Table1 in a SQL select.
 
Now if there is already an INSERT / MERGE / UPDATE operation going on Table1 then it will be on WRITE lock. So the SQL with READ lock will wait. 
In this scenario will TD system down grade the READ lock to ACCESS lock and return result from Table1?
 
I need to know this because if it is possible then I will implement this in a batch script. Please let me know.
 
Thanks
Santanu
