Good day all
-=00=-=-00-=-=0

Thanks to all the help that was given so far. Also thanks for your patience with me.

This is also related to "Transaction and Stored procedures."

I have 2 topics with questions
---------------------------
A) Does triggers on the database only get triggers when the transaction is commited ? Or can I assume that it
gets run inside of the transaction also. If this is the case and if I call stored procedures inside those triggers
to perform certain function that will define the next step in logic in my program code. Does these stored procedures
that is called via the databases before of after insert or update also exist inside my transaction ?

B) Locking of records. As previously explained with transaction and data stored on pages and then commited to database if all is fine etc.
i) When a record is locked thanks to my transaction. Is it a row level (record) or page level (all active ones on the cache page) lock ?
ii) What will lock the record ? only updates , inserts and deletes or does normal selects also lock records ?
iii) If I only start a transaction and then commit it immediately afterwards with absolutely nothing between it. Does a database lock appear at all ?


Thanks in Advance for all your help and patience
