I am using Oracle SQL (in SQLDeveloper, using the SQL Worksheet). I would like to print a statement before my select, such as
PRINT \'Querying Table1\';
SELECT
The main answer left out a step for new installs where one has to open up the dbms output window.
Then the script I used:
dbms_output.put_line('Start');
Another script:
set serveroutput on format wrapped;
begin
DBMS_OUTPUT.put_line('jabberwocky');
end;
for simple comments:
set serveroutput on format wrapped;
begin
DBMS_OUTPUT.put_line('simple comment');
end;
/
-- do something
begin
DBMS_OUTPUT.put_line('second simple comment');
end;
/
you should get:
anonymous block completed
simple comment
anonymous block completed
second simple comment
if you want to print out the results of variables, here's another example:
set serveroutput on format wrapped;
declare
a_comment VARCHAR2(200) :='first comment';
begin
DBMS_OUTPUT.put_line(a_comment);
end;
/
-- do something
declare
a_comment VARCHAR2(200) :='comment';
begin
DBMS_OUTPUT.put_line(a_comment || 2);
end;
your output should be:
anonymous block completed
first comment
anonymous block completed
comment2
PROMPT text to print
Note: must use Run as Script (F5) not Run Statement (Ctl + Enter)
You could put your text in a select statement such as...
SELECT 'Querying Table1' FROM dual;
If you don't want all of your SQL statements to be echoed, but you only want to see the easily identifiable results of your script, do it this way:
set echo on
REM MyFirstTable
set echo off
delete from MyFirstTable;
set echo on
REM MySecondTable
set echo off
delete from MySecondTable;
The output from the above example will look something like this:
-REM MyFirstTable
13 rows deleted.
-REM MySecondTable
27 rows deleted.
You could set echo to on:
set echo on
REM Querying table
select * from dual;
In SQLDeveloper, hit F5 to run as a script.
