Which of the following is the correct order of cursor operations in SQL?
ADECLARE, FETCH, OPEN, CLOSE, DEALLOCATE
BOPEN, DECLARE, FETCH, CLOSE, DEALLOCATE
CDECLARE, OPEN, FETCH, CLOSE, DEALLOCATE
DFETCH, DECLARE, OPEN, CLOSE, DEALLOCATE
Step-by-Step Solution
Solution:
Step 1: Recall the cursor lifecycle
You first DECLARE the cursor, then OPEN it to start fetching rows, FETCH rows one by one, CLOSE it when done, and finally DEALLOCATE to free resources.
Step 2: Match the correct sequence
Only DECLARE, OPEN, FETCH, CLOSE, DEALLOCATE follows this exact order. Other options mix the steps incorrectly.
Final Answer:
DECLARE, OPEN, FETCH, CLOSE, DEALLOCATE -> Option C
Quick Check:
Cursor lifecycle order = C [OK]
Quick Trick:Remember: Declare first, then open, fetch, close, deallocate [OK]
Common Mistakes:
Opening cursor before declaring
Fetching before opening
Not deallocating after closing
