PostgreSQL - Views and Materialized Views
You created a view with WITH CHECK OPTION but receive an error when trying to insert data through it. What is a likely cause?
AThe base table does not exist
BThe inserted data does not satisfy the view's WHERE condition
CThe view was created without SELECT privileges
DThe database is in read-only mode
Step-by-Step Solution
Solution:
  1. Step 1: Understand the role of WITH CHECK OPTION on inserts

    It enforces that inserted rows must satisfy the view's filter condition.
  2. Step 2: Identify why insert errors occur

    If inserted data violates the condition, the insert is rejected.
  3. Final Answer:

    The inserted data does not satisfy the view's WHERE condition -> Option B
  4. Quick Check:

    Insert error with CHECK OPTION = data violates condition [OK]
Quick Trick: Insert errors often mean data breaks view's filter [OK]
Common Mistakes:
  • Assuming base table missing causes this error
  • Thinking lack of SELECT privilege causes insert error
  • Blaming database read-only mode without checking
