- A
Replace SYSDATE with LOCALTIMESTAMP.
Why wrong: LOCALTIMESTAMP returns timestamp without time zone; SYSDATE includes time zone information.
- B
Use TO_DATE(SYSDATE, 'YYYY-MM-DD HH24:MI:SS') to convert the value.
Why wrong: SYSDATE is not a valid function in PostgreSQL; this would cause an error.
- C
Replace SYSDATE with CURRENT_TIMESTAMP.
CURRENT_TIMESTAMP returns date and time with time zone, equivalent to Oracle's SYSDATE.
- D
Replace SYSDATE with CURRENT_DATE in the converted procedure.
Why wrong: CURRENT_DATE returns only the date, not time, leading to incorrect results.

PCDOE Migrate Database Solutions Practice Question
This PCDOE practice question tests your understanding of migrate database solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization is migrating an Oracle database to Cloud SQL for PostgreSQL using Ora2Pg. During testing, a stored procedure that uses Oracle's SYSDATE produces incorrect results. What is the correct approach to handle this conversion?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Replace SYSDATE with CURRENT_TIMESTAMP.
Oracle's SYSDATE returns date and time; PostgreSQL equivalent is CURRENT_TIMESTAMP (or NOW()). Simply mapping to CURRENT_DATE would lose time component, breaking logic.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Replace SYSDATE with LOCALTIMESTAMP.
Why it's wrong here
LOCALTIMESTAMP returns timestamp without time zone; SYSDATE includes time zone information.
- ✗
Use TO_DATE(SYSDATE, 'YYYY-MM-DD HH24:MI:SS') to convert the value.
Why it's wrong here
SYSDATE is not a valid function in PostgreSQL; this would cause an error.
- ✓
Replace SYSDATE with CURRENT_TIMESTAMP.
Why this is correct
CURRENT_TIMESTAMP returns date and time with time zone, equivalent to Oracle's SYSDATE.
Related concept
Standard ACLs match source addresses.
- ✗
Replace SYSDATE with CURRENT_DATE in the converted procedure.
Why it's wrong here
CURRENT_DATE returns only the date, not time, leading to incorrect results.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related PCDOE ACL questions on filtering logic and placement.
