I want to give alias name to my column name in a stored procedure But its not coming as I want. Below is the code which I tried
STREX:='SELECT DISTINCT AM.APP_MST_ID, NVL(AM.APPLICATIONNAME,''-'') as ''APPLICATION NAME'', NVL(AD.URLPATH,''-'')URL, NVL(AM.PROJECTNO,''-'')PROJECTNO, NVL(AM.VSS_FOLDER_LOC,''-'')VSSFOLDERLOC,
NVL(AU.NAME, ''-'')SPOCUSER, NVL(AUR.NAME,''-'')REQUESTEDBY, NVL(AUD.NAME,''-'')DELIVERYMANAGER
FROM APPLICATION_MASTER AM
INNER JOIN APPLICATION_DETAILS AD
ON AM.APP_MST_ID = AD.APP_MST_ID
INNER JOIN APPUSER_UMS AU
ON AM.APP_MST_ID = AU.APP_USERID
INNER JOIN APPUSER_UMS AUR
ON AUR.APP_USERID = AM.REQUESTED_BY_APPUSRID
INNER JOIN APPUSER_UMS AUD
ON AUD.APP_USERID = AM.DELIVERY_MANAGER_APPUSRID
WHERE UPPER(AM.'|| P_PARAM_TYPE || ') ' || P_OPERATOR || ' :PARAM';
/* WHERE AM.'|| UPPER(P_PARAM_TYPE) ||' '|| P_OPERATOR || ' :PARAM'; */
DBMS_OUTPUT.PUT_LINE('STREX '|| STREX);
OPEN P_RETURN FOR STREX USING VAL;
I want to show as Application Name for first column
Try:
...SELECT DISTINCT AM.APP_MST_ID, NVL(AM.APPLICATIONNAME,''-'') as "Application Name"...
Double quotes (") are used to specify identifier names, single quotes (') are used to delimit character strings in data.

I am loading a file into a staging record using Application Engine. when ever there is blank in BU,Deptid etc... I have to capture what all columns are blank and update error text field with those values.
UPDATE SYSADM.PS_VI_EMP_TS SET ERR_TEXT =
SELECT ERROR FROM (SELECT * FROM (
SELECT CASE WHEN BUSINESS_UNIT = ' ' THEN 'BUSINESS_UNIT IS NULL' ELSE ' ' END AS ERROR FROM SYSADM.PS_VI_EMP_TS WHERE USERID='JCOOPER' AND ACTION = 'E' AND PROCESS_INSTANCE = '7852429'
UNION
SELECT CASE WHEN DEPTID = ' ' THEN 'DEPTID IS NULL' ELSE ' ' END AS ERROR FROM SYSADM.PS_VI_EMP_TS WHERE USERID='JCOOPER' AND ACTION = 'E' AND PROCESS_INSTANCE = '9852429'
UNION
SELECT CASE WHEN PROJECT_ID =' ' THEN 'PROJECT_ID IS NULL' ELSE ' ' END AS ERROR FROM SYSADM.PS_VI_EMP_TS WHERE USERID='JCOOPER' AND ACTION = 'E' AND PROCESS_INSTANCE = '9852429'
)) WHERE ERROR <> ' '
WHERE USERID='JCOOPER' AND ACTION = 'E' AND PROCESS_INSTANCE = '9852429'
The above script results as below.
ERROR
BUSINESS_UNIT IS NULL
DEPTID IS NULL
I want the result as below.
ERROR
BUSINESS_UNIT IS NULL,DEPTID IS NULL
I am using ListAgg function but facing errors as below.Any help would be great.
SELECT LISTAGG(BUSINESS_UNIT, ';') WITHIN GROUP(ORDER BY USERID)
FROM SYSADM.PS_VI_EMP_TS WHERE USERID='JCOOPER'
GROUP BY BUSINESS_UNIT
Facing the error:
ORA-00923: FROM keyword not found where expected
00923. 00000 - "FROM keyword not found where expected"
*Cause:
*Action:
Error at Line: 47 Column: 43
You overcomplicated things. You don't need two unions and listagg at all. Simple use concatenation of case... when, write your select like here:
select case business_unit when ' ' then 'BUSINESS_UNIT IS NULL; ' end ||
case deptid when ' ' then 'DEPTID IS NULL; ' end ||
case project_id when ' ' then 'PROJECT_ID IS NULL; ' end as error
from ps_vi_emp_ts
where userid = 'JCOOPER' and action = 'E' and process_instance = '9852429'

If your table has primary key then use it for update. Otherwise you can use merge with rowid. Or do it the way you did it if it worked for you, especially if there is only one row meeting criteria.
I have a procedure that expects a SELECT statement as a parameter.
If I run the SELECT Statement out of the procedure, it runs fine, but when I run it within the procedure i get the error:
The procedure :
data_dump(query_in => 'select * from reservation where type not in ('H','PURGE','E') ',
file_in => 'export_'||months_from||''||months_to||'.csv',
directory_in => 'C:\Users\Administrator\Desktop\test',
delimiter_in => '|' );
The query itself gives me the expected result.
select * from reservation where type not in ('H','PURGE','E', '|| other ||')
The error is: encountered the symbol 'H'.
Can it be because of the single quotes around the IN condition?
getting error missing right parenthesis:
(trunc(a.update_date) between (select add_months(TRUNC(SYSDATE), -(]'|| months_from ||q'[') ) from dual) and (select add_months(TRUNC(SYSDATE), -(]'|| months_to ||q'[') from dual))]'
You're passing quoted arguments within a string. You need to either escape those internal quotes:
data_dump(query_in => 'select * from reservation where type not in (''H'',''PURGE'',''E'') ',
file_in => 'export_'||months_from||''||months_to||'.csv',
directory_in => 'C:\Users\Administrator\Desktop\test',
delimiter_in => '|' );
Or use the alternative quoting mechanism:
data_dump(query_in => q'[select * from reservation where type not in ('H','PURGE','E') ]',
...
With your 'other' value you need to still include that in its own escape quotes:
data_dump(query_in => 'select * from reservation where type not in (''H'',''PURGE'',''E'','''|| other ||''')',
...
or (getting less readable now, perhaps):
data_dump(query_in => q'[select * from reservation where type not in ('H','PURGE','E',']' || other || q'[')]',
...
You can use dbms_output to debug this sort of thing, printing the generated argument and seeing if that matches what you've been running manually.
With your third partial code you've put closing single quotes after the (presumably numeric) variables:
(trunc(a.update_date) between (select add_months(TRUNC(SYSDATE), -(]'|| months_from ||q'[') ) from dual) and (select add_months(TRUNC(SYSDATE), -(]'|| months_to ||q'[') from dual))]'
^ ^
and you are, as the message says, missing a closing parenthesis in the second add_month call; so it should be (where ... is the rest of the statement that you haven't shown):
q'[ ... (trunc(a.update_date) between (select add_months(TRUNC(SYSDATE), -(]'
|| months_from ||q'[) ) from dual) and (select add_months(TRUNC(SYSDATE), -(]'
|| months_to ||q'[) ) from dual))]'
Again, this is basic debugging you can do by printing the generated statement and inspecting it or trying to run it manually.
Also you don't need the inner select from dual stuff or all the parentheses; you can just do:
q'[ ... trunc(a.update_date) between add_months(TRUNC(SYSDATE), -]'
|| months_from ||q'[) and add_months(TRUNC(SYSDATE), -]'|| months_to ||q'[)]'
I have the following query :
SELECT

INNER JOIN XXXXR i ON (i.udidx = ix.UDBENCH_UDIDX),
XXXXX m
WHERE ix.dt >= to_date(sdt_start,'DD.MM.YYYY')
AND ix.dt <= to_date(sdt_end,'DD.MM.YYYY')
AND ix.UDBENCH_UDIDX IN (select listagg( udfo,',') within group(ORDER BY udfo)
from XXXXX where pf_ticker is null )
AND i.szbez LIKE '%DFLT%'
AND ix.idas = m.idas;
I would like the part :
AND ix.UDBENCH_UDIDX IN (select listagg( udfo,',') within group(ORDER
BY udfo)
from XXXXX where pf_ticker is null )
Equivalent to : ix.UDBENCH_UDIDX IN ('blal','bll',blc') but it shows ix.UDBENCH_UDIDX IN (blal,bll,blc) and the result of my query is an empty table, do you know how to set listagg to have this result ( 'blal','bll',blc' instead of blal,bll,blc)?
Thanks
The IN operator doesn't work like that. You'd be comparing the UDBENCH_UDIDX values with a single string containing all udfo values, not all of the individual values of that column.
You can just use a subquery without the listagg():
AND ix.UDBENCH_UDIDX IN (select udfo from XXXXX where pf_ticker is null)
Or you can join to that table instead of using a subquery at all; something like:
FROM XXXX ix
INNER JOIN XXXXR i ON (i.udidx = ix.UDBENCH_UDIDX)
INNER JOIN XXXXX m ON (m.udfo = ix.UDBENCH_UDIDX)
WHERE ix.dt >= to_date(sdt_start,'DD.MM.YYYY')
AND ix.dt <= to_date(sdt_end,'DD.MM.YYYY')
AND i.szbez LIKE '%DFLT%'
AND ix.idas = m.idas
AND m.pf_ticker is null;
... assuming the old-style join to XXXXX m is supposed to be getting the data related to the subquery you're doing - it's hard to tell with obfuscated names. (It's not a good idea to mix old and new style joins anyway; or to use old-style joins at all). It's possible you might want that to be an outer join, or the driving table, or something else - again can't infer that from the information provided.
If you already had a set of string literals to look for then you would do something like:
IN ('val1', 'val2', 'val3')
but you don't have string literals, you have string values from a table, which are not the same. You don't need to, and shouldn't, enclose those column values in single quotes within the query. The single quotes denote a literal value which is to be treated as a string; the values in the column are already strings.
You can actually do what you asked:
select '''' || listagg(udfo, ''',''') within group (order by udfo) || '''' from ...
which would give you a comma-separated list of quoted values from your table (or an empty string, which is the same as null, if there are no matching rows. If you were generating a statement to run later then that might make some sense, but that isn't the case here.
I'm using Apex 4.2.4 and Oracle 11g. I have a mailing list application where I'm maintaining multiple mailing lists. A given recipient may belong to one or more lists. I'm using an Apex Shuttle to maintain the lists.
The source of all mailing recipients is in the table: mail_recipient. There are four important fields in mail_recipient:
prim_key
first_name
last_name
email_address
There is another table that stores the selected recipients for a given mailing list: mail_recipient_category: The important fields in mail_recipient_category are:
prim_key
recipient_fkey (this stores the prim_key from the mail_recipient table)
category
merge_check
There are two displayed items on the page. The category drop down list (P31_email_list) and the shuttle (P31_email_list_assignments)
The LOV for P31_email_list_assignments is:
Select last_name || ', ' || first_name || ' -- ' || email_address, prim_key from mail_recipient
order by 1;
The PL/SQL function body for the shuttle source is:
declare
emp_list apex_application_global.vc_arr2;
i number := 1;
begin
for r in (Select mr.last_name || ', ' || mr.first_name || ' -- ' || mr.email_address, mr.prim_key
From mail_recipient mr left outer join
mail_recipient_category mrc
On mr.prim_key = mrc.recipient_fkey
Where mrc.category = :P31_EMAIL_LIST)
loop
emp_list(i) := r.prim_key;
i := i + 1;
end loop;
return APEX_UTIL.TABLE_TO_STRING(emp_list, ':');
end;
There is also a single page process to update the database table mail_recipient_category. The process is executed on submit after computations and validations.
Begin
MERGE INTO MAIL_RECIPIENT_CATEGORY ss
USING (
Select
shuttle.column_value shuttle_st
, db.recipient_fkey db_st
from
table(string_to_coll(:P31_email_list_assignments)) shuttle
left outer join mail_recipient_category db
on shuttle.column_value = db.recipient_fkey
and db.category = :P31_email_list) t
on (ss.recipient_fkey = t.db_st
and ss.category = :P31_email_list
)
when matched
then
update
set
ss.merge_check = ss.merge_check
delete
where
t.shuttle_st is null and ss.category = :P31_email_list
-- t.shuttle_st is null
when not matched
then
insert
(recipient_fkey, category)
values
(t.shuttle_st, :P31_email_list);
end;
The shuttle works fine to load from left to right and save items. The problem I'm having is deselecting items from the right side to the left side of the shuttle. After moving a a mail recipient from the right to the left side, when I press the submit button, the items don't leave the right side of the shuttle and the process doesn't delete the row from the mail_recipient_category table.
Thanks for your help with this.
After working with a very experienced colleague, we determined that the page process was at fault. Specifically, the Delete clause of the Merge statement doesn't seem to work for this shuttle. We ended up adding a separate Delete statement after the the Merge statement in the page process.
I also dropped the mail_recipient_category table and am now using the more meaningful name mail_recipient_list.
The shuttle field name is (p31_email_list_assignments).
The working shuttle LOV Definition code is:
Select last_name || ', ' || first_name || ' -- ' || email_address, prim_key
From mail_recipient
order by 1;
The working shuttle Source code is:
declare
mail_list apex_application_global.vc_arr2;
i number := 1;
begin
for r in (Select mr.last_name || ', ' || mr.first_name || ' -- ' || mr.email_address, mr.prim_key
From mail_recipient mr left join
mail_recipient_list mrl
On mr.prim_key = mrl.recipient_fkey
Where mrl.list = :P31_EMAIL_LIST)
loop
mail_list(i) := r.prim_key;
i := i + 1;
end loop;
return APEX_UTIL.TABLE_TO_STRING(mail_list, ':');
end;
The working After Submit page process code is:
Begin
Merge Into MAIL_RECIPIENT_LIST mrl
Using (
Select
shuttle.column_value shuttle_cv
, db.recipient_fkey db_rfk
From
table(string_to_coll(:P31_email_list_assignments)) shuttle
left outer join mail_recipient_list db
on shuttle.column_value = db.recipient_fkey
and db.list = :P31_email_list) t
On (mrl.recipient_fkey = t.db_rfk
And mrl.list = :p31_email_list
)
When Matched
Then
Update
Set
mrl.merge_check = mrl.merge_check
-- Delete
-- Where
-- t.shuttle_cv is null
When Not Matched
Then
Insert
(recipient_fkey, list)
Values
(t.shuttle_cv, :P31_email_list);
/* The commented-out delete clause of the Merge statement never worked with this shuttle.
The following delete statement will every time this page process is called
*/
Delete from MAIL_RECIPIENT_LIST
Where instr(':' || :P31_email_list_assignments || ':',':' || recipient_fkey || ':') = 0
And list = :P31_email_list;
end;
I hope someone finds this useful.
Given an object identified by the form owner.tablename; how do I split the owner and table name up?
Both my ideas of either string tokenization or select owner, object_name from all_objects where owner || '.' || object_name = 'SCHEMA.TABLENAME' seem like hacks.
You can use DBMS_UTILITY.name_tokenize for this purpose.
This procedure calls the parser to parse the given name as "a [. b [.
c ]][# dblink ]". It strips double quotes, or converts to uppercase if
there are no quotes. It ignores comments of all sorts, and does no
semantic analysis. Missing values are left as NULL.
e.g.
DBMS_UTILITY.NAME_TOKENIZE
( name => 'SCHEMA.TABLENAME'
, a => v_schema
, b => v_object_name
, c => v_subobject -- ignore
, dblink => v_dblink
, nextpos => v_nextpos -- ignore
);

SELECT SUBSTR('SCHEMA.TABLENAME', 0, INSTR('SCHEMA.TABLENAME', '.') - 1) OWNER,
SUBSTR('SCHEMA.TABLENAME', INSTR('SCHEMA.TABLENAME', '.') + 1) TABLE_NAME
