sql - SPOOL command doesnt save result in query

Question

I'm using SQL Developer and I'm trying to save result of a query into the text file using spool command.

spool D:file.txt
SELECT * FROM TABLE
SPOOL OFF

When I open created file it only has my query in it: "SELECT * FROM TABLE" but not result of it. What am I doing wrong?

Answer 1

Try to execute it with a query which returns fewer rows to see if you have any other problems. After you make it work, try your query. Also there is a difference between Run Statement and Run Script.

In the following query

spool '/home/atilla/file.txt'

SELECT * FROM DUAL;

SPOOL OFF

If I use Run Statement, I get following file

   > SELECT * FROM DUAL

If I use Run Script, I get following file

> SELECT * FROM DUAL
DUMMY
