I am using pgAdmin III, PostgreSQL tools, Version 1.2.0 Beta on Windows XP Pro.
The following query, when executed as a stand alone query returns an error, correctly, that the column name is not valid:
Query A) Select patientorder_key from patientorder where visit_key = 250314 and provider_key = 301;
The correct syntax should be:
Query B) Select patientorder.key from patientorder where visit_key = 250314 and provider_key = 301;
However, when the query with the incorrect column name (Query A) is embedded in a where clause, column validation does not happen, no error is displayed, and PGAdmin apparently ignores the where clause all together, resulting in complete data deletion, as if there were no where clause:
Begin;
Delete from testorder where patientorder_key in
(Select patientorder_key from patientorder where visit_key = 250314 and provider_key = 301);
End;
This resulted in massive amounts of data being deleted erroneously.
I believe this is a bug.
Not in pgAdmin. pgAdmin passes the query verbatim to PostgreSQL, making no attempt to parse or understand it at all. PostgreSQL parses, plans and executes the query and returns any resulting data or messages to pgAdmin which displays it/them.
I would suggest producing an easily re-createable test case and posting it to [EMAIL PROTECTED]
