问题
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?
回答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

It looks to me that you're not executing the query, just entering it into the command buffer. You need to add a semicolon or a slash to actually execute it.
