Question

How to increase buffer size in Oracle SQL Developer to view all records (there seems to be a certain limit set at default)? Any screen shots and/or tips will be very helpful.

Answer 1

It is easy, but takes 3 steps:

1. In SQL Developer, enter your query in the "Worksheet" and highlight it, and press F9 to run it. The first 50 rows will be fetched into the "Query Result" window.
2. Click on any cell in the "Query Result" window to set the focus to that window.
3. Hold the Ctrl key and tap the "A" key.

All rows will be fetched into the "Query Result" window!
