Dear Oliver Elphick ,
If I am not wrong PostgreSQL select statements works on committed data
thus the new
inserted data at #3 must not be available to sai_func_b() till #5
No. All operations by a single transaction are visible inside the
transaction. Therefore an encapsulated function can see anything already
done in the whole transaction. A function must be entirely inside a
transaction and cannot start a transaction, so there can never be any
problem about this.
Loads of thanks for the kind reply .
Would be greatefull if you kindly post some links/refrences to support your answer for the said.
Thanks one again .
