Hello.
I have found an interesting FRONTEND/BACKEND protocol behaviour. Let's
consider following query:
"SELECT 1; SELECT 2; SELECT3; SELECT4;"
1) If I send it as a simple query - I'm getting:
- correct results for SELECT 1; SELECT 2; SELECT3; SELECT4;
- and then one ReadyForQuery response
from backend.
[send_simple.log & recv_simple.log]
2) If I send it as 'PREPARE "SQL_CUR1" AS SELECT 1; SELECT 2; SELECT3;
SELECT4;' and then 'EXECUTE "SQL_CUR1" - I'm getting:
- results for SELECT 1; SELECT2; SELECT 3;
- ReadyForQuery response
- results for SELECT 4;
- one more ReadyForQuery response
from backend
[send_prepared.log & recv_prepared.log]
Is this behavour is correct and expected?
P.s. Tested on Windows with PostgreSQL 8.0, 8.1 and 8.2 with the same
results.
Thank You,
Andrei.
