Run sql code with variables in Oracle SQL Developer code window - oracle

Question

I'm writing code using Oracle SQL Developer. I have a simple select statement that works:
SELECT
CFS.CAE_SEC_ID,
CFS.FM_SEC_CODE,
CFS.LAST_USER_ID,
case
when 1 = 1 then
sl.usbank_to_edit
else
case
when 'ENT\CB174' = CFS.last_user_id then
sl.owner_to_edit
else
sl.to_edit
end
end canEdit
FROM
CAEDBO.CAE_FOF_SECURITY CFS
INNER JOIN caedbo.CAE_DATA_SET_ELEMENT CDSE_STAT
ON (CDSE_STAT.DATA_SET_ELEMENT_ID = CFS.APPR_STATUS)
INNER JOIN caedbo.CAE_STATE_LOOKUP sl
ON (sl.object_state = CDSE_STAT.data_set_element_id)
where
cfs.CAE_SEC_ID in (3741, 3744, 3748, 3752);
However I want to add some variables to it and reference the variables in the statement, similar to below, and also run it in the code window. How do I do this correctly?
DECLARE
p_USBank_n NUMBER;
p_user_id_c VARCHAR2(20);
BEGIN
p_USBank_n := 1;
p_user_id_c := 'ENT\CB174';
SELECT
CFS.CAE_SEC_ID,
CFS.FM_SEC_CODE,
CFS.LAST_USER_ID,
case
when p_USBank_n = 1 then
sl.usbank_to_edit
else
case
when p_user_id_c = CFS.last_user_id then
sl.owner_to_edit
else
sl.to_edit
end
end canEdit
FROM
CAEDBO.CAE_FOF_SECURITY CFS
INNER JOIN caedbo.CAE_DATA_SET_ELEMENT CDSE_STAT
ON (CDSE_STAT.DATA_SET_ELEMENT_ID = CFS.APPR_STATUS)
INNER JOIN caedbo.CAE_STATE_LOOKUP sl
ON (sl.object_state = CDSE_STAT.data_set_element_id)
where
cfs.CAE_SEC_ID in (3741, 3744, 3748, 3752);
END;
When I run this in a sql window I get the message below:
Error report:
ORA-06550: line 8, column 5:
PLS-00428: an INTO clause is expected in this SELECT statement
06550. 00000 - "line %s, column %s:\n%s"

if I am reading this correctly, I think you are looking for Oracle Substitution variables.
this will prompt you each time to input the values, by using &val it will prompt you # runtime
SELECT
CFS.CAE_SEC_ID,
CFS.FM_SEC_CODE,
CFS.LAST_USER_ID,
CASE
when &p_USBank_n = 1 then
sl.usbank_to_edit
else
CASE
when '&p_user_id_c' = CFS.last_user_id then
sl.owner_to_edit
else
sl.to_edit
end
end canEdit
FROM
CAEDBO.CAE_FOF_SECURITY CFS
INNER JOIN caedbo.CAE_DATA_SET_ELEMENT CDSE_STAT
ON (CDSE_STAT.DATA_SET_ELEMENT_ID = CFS.APPR_STATUS)
INNER JOIN caedbo.CAE_STATE_LOOKUP sl
ON (sl.object_state = CDSE_STAT.data_set_element_id)
where
CFS.CAE_SEC_ID IN (3741, 3744, 3748, 3752);
change it to &&var to have it retain the value, then use
UNDEFINE var
to clear it
Now you can set these at the top of the page (thus avoiding the prompt) by utilizing DEFINE as such
DEFINE XYZ = 5
DEFINE AAA = to_date('10/10/2010','mm/dd/rrrr')
DEFINE textString = AaBbCc
SELECT &&XYZ b, &&AAA a, '&&textString' textString
from dual ;
B A TEXTSTRING
---------------------- ------------------------- ----------
5 10.OCT.2010 00:00 AaBbCc
--typing define will show you all the "defined" values
define
DEFINE XYZ = "5"
DEFINE TEXTSTRING = "AaBbCc"
DEFINE AAA = "to_date('10/10/2010','mm/dd/rrrr')"
the double ampersand will 'retain' the value until you UNDEFINE it (see above) or redefine it.

The error message explains the problem; inside a PL/SQL block you have to select INTO something, and you can't just dump the results of a query to screen as you can with plain SQL. (There are ways to do it but probably overly complicated for what it looks like you're trying to achieve here).
If you don't want to use substitution variables as #Harrison suggested, you can use bind variables which you define at the start in a separate anonymous block. You can then refer to the bind variable in the plain SQL:
var p_usbank_n number;
var p_user_id_c varchar2(20);
exec :p_usbank_n := 1;
exec :p_user_id_c := 'ENT\CB174';
select
cfs.cae_sec_id,
cfs.fm_sec_code,
cfs.last_user_id,
case
when 1 = :p_usbank_n then
sl.usbank_to_edit
when cfs.last_user_id = :p_user_id_c then
sl.owner_to_edit
else
sl.to_edit
