I have columns in table something like
answeremail,
answertime,
ata,
atacomment,
ataid,
atainternalnumber,
atanumber,
atatype,
author,
becomeatafromdeviation,
becomeexternalatafrominternal,
becomefastfromothertype,
briefdescription,
city,
client_answer_attachment,
clientcomment,
confirmstatus,
created_at,
deviation,
deviationnumber,
deviationtype,
duedate,
emailsent,
financeid,
forfortnox,
fromfortnox,
is_deleted,
locked,
name,
parentata,
paymenttype,
pdfurl,
projectid,
quantity,
reason,
revisiondate,
startdate,
status,
street,
suggestion,
token,
type,
unit,
userid,
zip
I want to create SELECT statment to retrive some of this column but without specify column name something like this.
SELECT * FROM ata WHERE 'field' = 'argument'
Is there any solution for this problem or either I need to specify all those column in SELECT statment ?
Not (just) in SELECT, but in WHERE. Otherwise, how will query know which columns to check?
But - beware of datatypes. Oracle will try to implicitly convert one datatype to another. Sometimes, it'll succeed (e.g. to convert number 1 to string '1'), sometimes it'll fail (e.g. convert string 'A' to number or string 'AB23F' to date value).
Therefore, although you can try to write query which will write query for you, it might take some time to actually make it work properly. PL/SQL is probably what you'll end up with.
An example which checks all tables in my schema that contain a column named PHONE_NUMBER and searches for a row whose phone number contains 654. This script returns tables that contain such a value; you'd return something else - list of columns? All columns? Can't tell.
That's just a starting point. Good luck!

There is one short solution using xml:
https://dbfiddle.uk/?rdbms=oracle_18&fiddle=e5efc164b77a55b2ecf5d4bf85d589a5
select/*+ no_xml_query_rewrite */ *
from
xmltable(
'for $row in ora:view("SAMPLE_DATA")
let $col := $row/ROW/*[text() eq $search]
where $col ne ""
return element R {
attribute X {$col},
$row
}'
passing
'BB' as "search"
columns
found_col varchar2(30) path '#X'
,row_data xmltype path '.'
);
Results:
FOUND_COL ROW_DATA
------------------------------ ----------------------------------------------------------------------------------------------------
BB <R X="BB"><ROW><COLA>10A</COLA><COLB>BB</COLB><COLC>00</COLC></ROW></R>

BB <R X="BB"><ROW><COLA>10A</COLA><COLB>BB</COLB><COLC>30</COLC></ROW></R>
BB <R X="BB"><ROW><COLA>10A</COLA><COLB>BB</COLB><COLC>40</COLC></ROW></R>
From your description, I think you want to retrive the columns which spicified by the where clause only, and to omit the other columns.
I don't think this is allowed by simple sql statement. In the oracle document, at the select_list section, I can't see any solution for this question.
see https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/SELECT.html#GUID-CFA006CA-6FF1-4972-821E-6996142A51C6
If you really want, you can use pl/sql.
I'm trying to make procedure to select weekly music rank based on hits and likes.
create or replace procedure select_rank(
v_title IN music.title%TYPE,
v_release_date IN music.release_date%TYPE,
v_hit IN music.hit%TYPE
) is
v_cnt number := 0;
BEGIN
select music.title, music.release_date, count(melon_user.user_idx) as likes, music.hit
into v_rank, v_title, v_cnt, v_release_date, v_hit
from melon_user, user_like_music, music
where melon_user.user_idx = user_like_music.user_idx
and user_like_music.music_idx = music.music_idx
group by music.title, music.hit, music.release_date
order by count(melon_user.user_idx) desc, music.hit desc;
DBMS_OUTPUT.PUT_LINE('v_title: ' || v_title);
DBMS_OUTPUT.PUT_LINE('v_cnt: ' || v_cnt);
DBMS_OUTPUT.PUT_LINE('v_release_date: ' || v_release_date);
DBMS_OUTPUT.PUT_LINE('v_hit: ' || v_hit);
END select_rank;
/
But I keep getting error says
PLS-00403: expression 'V_RELEASE_DATE' cannot be used as an
INTO-target of a SELECT/FETCH statement
PLS-00403: expression 'V_RELEASE_DATE' cannot be used as an
INTO-target of a SELECT/FETCH statement
PLS-00403: expression 'V_RELEASE_DATE' cannot be used as an
INTO-target of a SELECT/FETCH statement
how do I fix this?
In the procedure's signature you have:
v_release_date IN music.release_date%TYPE,
v_release_date is an IN parameter and will be read only. If you want to assign values to it wthin the procedure and return them then make it an OUT (or IN OUT) parameter.
However, you have also:
Not declared the v_rank variable.
Your query appears likely to return multiple rows - SELECT .. INTO .. will only work for queries that return a single row. If this is the case then you either want to use BULK COLLECT INTO or return a cursor.
I have to construct a block to pull information from two tables using a cursor. As a further challenge, I have to identify the first item on the pull. I tried to use an IF statement to work through this. It errors out in several areas and I have no idea what I am doing wrong. Not asking for the answer per say, just enough of a push to get me moving again. Thanks. Here is the code I've put together so far:
DECLARE
CURSOR cur_pled IS
SELECT dd_pledge.idpledge, dd_pledge.pledgeamt, dd_pledge.paymonths, dd_payment.paydate, dd_payment.payamt
FROM dd_pledge, dd_payment
WHERE dd_payment.idpledge = dd_pledge.idpledge AND
dd_pledge.idpledge = 104
ORDER BY dd_pledge.idpledge, dd_payment.paydate;
TYPE type_pled IS RECORD
(pledID dd_pledge.idpledge%TYPE,
pledAmt dd_pledge.pledgeamt%TYPE,
payMonths dd_pledge.paymonths%TYPE,
payDate dd_payment.paydate%TYPE,
payAmt dd_payment.payamt%TYPE);
rec_pled type_pled;
lv_id_num dd_pledge.idpledge%TYPE := 0;
BEGIN
OPEN cur_pled;
LOOP
FETCH cur_pled INTO rec_pled;
EXIT WHEN cur_pled%NOTFOUND;
IF rec_pled.type <> lv_id_num THEN
DBMS_OUTPUT.PUT_LINE('First Payment');
ELSE DBMS_OUTPUT.PUT_LINE('Other Payment');
END IF;
END LOOP;
CLOSE cur_pled;
DBMS_OUTPUT.PUT_LINE(pledID || ' ' || dd_pledge.pledgeamt || ' ' ||
dd_pledge,payMonths || ' ' || dd_payment.payDate || ' ' ||
dd_payment.payAmt);
END;
There are loads of errors in your code. If you had formatted it correctly, you would have spotted some of them yourself!
Things that leapt out at me:
You're referring to dd_pledge in the final dbms_output.put_line, but dd_pledge isn't a variable. I think you meant to use rec_pled instead.
You refer to pledID in your final dbms_output.put_line statement - but this is a field defined in the record type, NOT a defined variable. I think you probably meant to use rec_pled.pledid
You're selecting the results of the cursor into rec_pled.type - however, "type" is not a field declared in the type_pled's definition! Did you mean rec_pled.idpledge instead?
You have dd_pledge,payMonths in your final dbms_output.put_line statement - the comma should be a full stop: rec_pled.payMonths
You're outputting the results after you've closed the results. Because this is just a record variable, you're only going to be outputting the results from the last row in the query.
Why aren't you doing a cursor for loop? That takes care of the exiting and declaring a record for you.
Anyway, I think you can achieve your results by using an analytic function in your query, rather than needing to use PL/SQL to do the work:
SELECT plg.idpledge,
plg.pledgeamt,
plg.paymonths,
pay.paydate,
pay.payamt,
case when row_number() over (partition by plg.idpledge, pay.paydate) = 1 then 'First Payment'
else 'Other Payment'
end type_of_payment
FROM dd_pledge plg
inner join dd_payment pay on (pay.idpledge = plg.idpledge)
--WHERE plg.idpledge = 104 -- add back in if you really need to do it for a single id
ORDER BY plg.idpledge, pay.paydate;
I have created a pipelined function which returns a table. I use this function like a dynamic view in another function, in a with clause, to mark certain records. I then use the results from this query in an aggregate query, based on various criteria. What I want to do is union all these aggregations together (as they all use the same source data, but show aggregations at different heirarchical levels).
When I produce the data for individual levels, it works fine. However, when I try to combine them, I get an ORA-12840 error: cannot access a remote table after parallel/insert direct load txn.
(I should note that my function and queries are looking at tables on a remote server, via a DB link).
Any ideas what's going on here?
Here's an idea of the code:
function getMatches(criteria in varchar2) return myTableType pipelined;
...where this function basically executes some dynamic SQL, which references remote tables, as a reference cursor and spits out the results.
Then the factored queries go something like:
with marked as (
select id from table(getMatches('OK'))
),
fullStats as (
select mainTable.id,
avg(nvl2(marked.id, 1, 0)) isMarked,
sum(mainTable.val) total
from mainTable
left join marked
on marked.id = mainTable.id
group by mainTable.id
)
The reason for the first factor is speed -- if I inline it, in the join, the query goes really slowly -- but either way, it doesn't alter the status of whatever's causing the exception.
Then, say for a complete overview, I would do:
select sum(total) grandTotal
from fullStats
...or for an overview by isMarked:
select sum(total) grandTotal
from fullStats
where isMarked = 1
These work fine individually (my pseudocode maybe wrong or overly simplistic, but you get the idea), but as soon as I union all them together, I get the ORA-12840 error :(
EDIT By request, here is an obfuscated version of my function:
function getMatches(
search in varchar2)
return idTable pipelined
as
idRegex varchar2(20) := '(05|10|20|32)\d{3}';
searchSQL varchar2(32767);
type rc is ref cursor;
cCluster rc;
rCluster idTrinity;
BAD_CLUSTER exception;
begin
if regexp_like(search, '^L\d{3}$') then
searchSQL := 'select distinct null id1, id2_link id2, id3_link id3 from anotherSchema.linkTable#my.remote.link where id2 = ''' || search || '''';
elsif regexp_like(search, '^' || idRegex || '(,' || idRegex || || ')*$') then
searchSQL := 'select distinct null id1, id2, id3 from anotherSchema.idTable#my.remote.link where id2 in (' || regexp_replace(search, '(\d{5})', '''\1''') || ')';
else
raise BAD_CLUSTER;
end if;
open cCluster for searchSQL;
loop
fetch cCluster into rCluster;
exit when cCluster%NOTFOUND;
pipe row(rCluster);
end loop;
close cCluster;
return;
exception
when BAD_CLUSTER then
raise_application_error(-20000, 'Invalid Cluster Search');
return;
when others then
raise_application_error(-20999, 'API' || sqlcode || chr(10) || sqlerrm);
return;
end getMatches;
It's very simple, designed for an API with limited access to the database, in terms of sophistication (hence passing a comma delimited string as a possible valid argument): If you supply a grouping code, it returns linked IDs (it's a composite, 3-field key); however, if you supply a custom list of codes, it just returns those instead.
I'm on Oracle 10gR2; not sure which version exactly, but I can look it up when I'm back in the office :P
To be honest no idea where the issue came from but the simplest way to solve it - create a temporary table and populate it by values from your pipelined function and use the table inside WITH clause. Surely the temp table should be created but I'm pretty sure you get serious performance shift because dynamic sampling isn't applied to pipelined functions without tricks.
p.s. the issue could be fixed by with marked as ( select /*+ INLINE / id from table(getMatches('OK'))) but surely it isn't the stuff you're looking for so my suggestion is confirmed WITH does something like 'insert /+ APPEND*/' inside it'.
I am developing an application in Oracle APEX. I have a string with user id's that is comma deliminated which looks like this,
45,4932,20,19
This string is stored as
:P5_USER_ID_LIST
I want a query that will find all users that are within this list my query looks like this
SELECT * FROM users u WHERE u.user_id IN (:P5_USER_ID_LIST);
I keep getting an Oracle error: Invalid number. If I however hard code the string into the query it works. Like this:
SELECT * FROM users u WHERE u.user_id IN (45,4932,20,19);
Anyone know why this might be an issue?
A bind variable binds a value, in this case the string '45,4932,20,19'. You could use dynamic SQL and concatenation as suggested by Randy, but you would need to be very careful that the user is not able to modify this value, otherwise you have a SQL Injection issue.
A safer route would be to put the IDs into an Apex collection in a PL/SQL process:
declare
array apex_application_global.vc_arr2;
begin
array := apex_util.string_to_table (:P5_USER_ID_LIST, ',');
apex_collection.create_or_truncate_collection ('P5_ID_COLL');
apex_collection.add_members ('P5_ID_COLL', array);
end;
Then change your query to:
SELECT * FROM users u WHERE u.user_id IN
(SELECT c001 FROM apex_collections
WHERE collection_name = 'P5_ID_COLL')
An easier solution is to use instr:
SELECT * FROM users u
WHERE instr(',' || :P5_USER_ID_LIST ||',' ,',' || u.user_id|| ',', 1) !=0;
tricks:
',' || :P5_USER_ID_LIST ||','
to make your string ,45,4932,20,19,
',' || u.user_id|| ','
to have i.e. ,32, and avoid to select the 32 being in ,4932,
I have faced this situation several times and here is what i've used:
SELECT *
FROM users u
WHERE ','||to_char(:P5_USER_ID_LIST)||',' like '%,'||to_char(u.user_id)||',%'
ive used the like operator but you must be a little carefull of one aspect here: your item P5_USER_ID_LIST must be ",45,4932,20,19," so that like will compare with an exact number "',45,'".
When using it like this, the select will not mistake lets say : 5 with 15, 155, 55.
Try it out and let me know how it goes;)

Create a native query rather than using "createQuery/createNamedQuery"
The reason this is an issue is that you cannot just bind an in list the way you want, and just about everyone makes this mistake at least once as they are learning Oracle (and probably SQL!).
When you bind the string '32,64,128', it effectively becomes a query like:
select ...
from t
where t.c1 in ('32,64,128')
To Oracle this is totally different to:
select ...
from t
where t.c1 in (32,64,128)
The first example has a single string value in the in list and the second has a 3 numbers in the in list. The reason you get an invalid number error is because Oracle attempts to cast the string '32,64,128' into a number, which it cannot do due to the commas in the string.
A variation of this "how do I bind an in list" question has come up on here quite a few times recently.
Generically, and without resorting to any PLSQL, worrying about SQL Injection or not binding the query correctly, you can use this trick:
with bound_inlist
as
(
select
substr(txt,
instr (txt, ',', 1, level ) + 1,
instr (txt, ',', 1, level+1) - instr (txt, ',', 1, level) -1 )
as token
from (select ','||:txt||',' txt from dual)
connect by level <= length(:txt)-length(replace(:txt,',',''))+1
)
select *
from bound_inlist a, users u
where a.token = u.id;
If possible the best idea may be to not store your user ids in csv! Put them in a table or failing that an array etc. You cannot bind a csv field as a number.
Please dont use: WHERE ','||to_char(:P5_USER_ID_LIST)||',' like '%,'||to_char(u.user_id)||',%' because you'll force a full table scan although with the users table you may not have that many so the impact will be low but against other tables in an enterprise environment this is a problem.
EDIT: I have put together a script to demonstrate the differences between the regex method and the wildcard like method. Not only is regex faster but it's also a lot more robust.

Solution from Tony Andrews works for me. The process should be added to "Page processing" >> "After submit">> "Processes".
As you are Storing User Ids as String so You can Easily match String Using Like as Below
SELECT * FROM users u WHERE u.user_id LIKE '%'||(:P5_USER_ID_LIST)||'%'
For Example
:P5_USER_ID_LIST = 45,4932,20,19
Your Query Surely Will return Any of 1 User Id which Matches to Users table
This Will Surely Resolve Your Issue , Enjoy
you will need to run this as dynamic SQL.
create the entire string, then run it dynamically.
