Subj:   Re: Inserting/Updating same target table simultaneously by multiple sessions without locking
From:   Dave Wellman


Neither of those options will work for you.

Both INSERT/SELECT and MERGE take table level, write locks of the target table.

If this process has its source data outside of Teradata then you can use TPT. A TPT job can read data from multiple sources and then insert the data into a single table.
