subquery returns no row in the main query, but hard returns the value of the master query

Oracle 11g, Solaris SPARC 64-bit:

This is the master query: its not to return all the lines

Select count (*) in the sadmin.usr_mods where to_char (ts_id) in ((select to_char (rtrim (ltrim(TS_MODULES,','), ',')) in the sadmin.usr_rfc where TS_KINTANA_PACKAGE_NUMBER = '123' and ts_projectid = 3));

COUNT (*)

----------

But wherever if I use subquery only returns he lines:

SQL > select rtrim (ltrim(TS_MODULES,','), ',') from the sadmin.usr_rfc where TS_KINTANA_PACKAGE_NUMBER = '123' and ts_projectid = 3;

RTRIM (LTRIM(TS_MODULES,','), ',')

--------------------------------------------------------------------------------

49,54

If I use these values as hardcoded to a select master it will return 2 rows:

SQL > select count (*) in the sadmin.usr_mods where to_char (ts_id) in ('49 ', ' 54');

COUNT (*)

----------

TS_MODULES datatype is CLOB

TS_ID datatype is set to number

Help, please

with

usr_rfc as

(select 3 ts_projectid, 123 ts_kintana_package_number, to_clob(',49,54,') ts_modules

of the double

usr_mods as

(select ts_id 49 Union double all the)

Select 50 in all double union

Select double 54

)

Select count (*)

Subquery returns the same value but no returnet lines
HY all

First of all excuse me for my English. I know that is very bad.

I have a very annoying problem...

I habe a query like this

Select the car of cars where car_color = (select color color where car_id = '5452')

My real Qery is mor complicated, but this is how it works.

Now the problem:

If I run the first query select car of cars where car_color = 'black' the query returns a value.

If I run the subquery *(select color from Colors where car_id ='5452') * the subquery returns a value (black)

If I run the query and subquery select car of cars where car_color = (select color color where car_id = '5452')
I get no value :(

How this bee? If I take the (black) result of the subquery, and paste of STIs in the first request, then I get a value.
But if I use the two querys it works.

Thank you for your support

Without your thing, I'll never be able to see the problem. Toad is really stupid as I think?

It has nothing to do with the toad. You will get the same results in SQL * more. Most of the tools on the client side display the nonprinting characters such as spaces. And in your case, string returned by the subquery has had new line at the end. Anyway, the other way to understand would compare dumps of returned strings:
```
select DUMP(LTRIM(RTRIM(rem.PSTREM_KURZ_BEZ))) from p_pveps_episode eps,  p_pvrep_re rep, p_strem_rechempf rem
WHERE
eps.allmnd_mandant='Test' and
eps.ppveps_aufnr='101224' and
eps.allmnd_mandant=rep.allmnd_mandant and
eps.ppveps_epsnr=rep.ppveps_epsnr and rep.pstrem_ident=rem.pstrem_ident -- {and ltrim(rtrim(rem.PSTREM_KURZ_BEZ)) =} quotet to show result
```
SY.

return the empty record only when no results not returned by the main query
It is a question of SQL (not PL/SQL)...

Let's say I have the following text:

Full_name SELECT NULL, NULL, NULL last_update_date address
OF the double
UNION ALL
SELECT full_name, address, last_update_date
Employees
WHEN TRUNC (sysdate) = TRUNC (last_update_date)

If the second part of the query retrieves no rows, it works beautifully and I get a blank line; However, if the second part of the query returns records, I get a blank line over my dataset I want.

How can I create a SQL statement that executes only the first query (before the union all) when no result is returned from the second. Also, I don't want to exceute the query twice only if I can get a count of the records because my actual query is much more complex than the example I've provided here.

Thanks in advance!

Hello

You can try to use a subquery factoring (WITH clause)
The query is executed only once, the query results are cached in memory or in a temporary table.
and you can view these results several times in the main query:
```
WITH second_query AS (
  -- your second query here
  SELECT full_name, address, last_update_date
  FROM employees
  WHERE TRUNC(sysdate)=TRUNC(last_update_date)
)
SELECT full_name, address, last_update_date
FROM second_query
UNION ALL
SELECT NULL full_name, NULL address, NULL last_update_date
FROM dual
WHERE NOT EXISTS ( SELECT 1 FROM second_query)
```

Simple query with a subquery returns the result of 'bad '.

So, I wanted to see the space allocated for users created in the last 4 days. The following query should return only 27 cases because the subquery returns only 27 records. Instead, he returned 66 entries!

select username, tablespace_name, max_bytes/1024/1024 quotaInMB
from dba_ts_quotas
where username in (select username from dba_users where created > sysdate-4);

No idea why? I know this isn't a bug with oracle. It's just that I didn't eat fish lately.

DBA_TS_QUOTAS does not have the space, but rather the maximum allowed for a given user.

What happens if your user John has Quotas on 3 tablespace TBS1 and TBS3 and TBS2?
You can't expect the outer query to retrieve only the more than 27 just line because the inner query returns 27 rows.

For the space allocated by the storage space for newly created users, you'd better ask dba_segments. something like:

select owner, tablespace_name, trunc(sum(bytes)/1024/1024) alloc_mb
from dba_segments
where owner in (select username from dba_users where created > sysdate - 4)
group by owner, tablespace_name
order by owner, tablespace_name;

expected output
-------------------
COL1    RND_COL
A       Multiple
A       Multiple
D       E
E       NULL

Hello

Here's another way. It's like the solution in response #1, but it does not use a subquery:

SELECT t.col1

CASE

WHEN COUNT (DISTINCT t2.col2) > 1

THEN "Multiple."

For ANOTHER MIN (t2.col2)

END AS rnd_col

T

LEFT OUTER JOIN t2 ON t2.col1 = t.col1

GROUP OF t.col1, t.col2, t.col3

ORDER BY t.col1

;

This assumes that in table t (col1, col2, col3) combination is unique. If theat is not the case, change the GROUP BY clause, but you need to ensure that all lines of t becomes a separate group.

DECODE does not work in the WHERE clause when subquery returns more than one line
Hi gurus,

I want to write a query against the table CCENTERS (Script given below) and wait for the following result:

1. in the transition from a value of 0 for the ID, it returns all the rows in the table.
2. in the passage of one value other than 0, it returns the row corresponding to the given value and all its records of the child.

CCENTER has parent-child relationship in the column ID and the BASE. I use a query with the DECODE function. but the function in the WHERE clause is not capable of managing the subquery with multiple lines of DECODE.

*************************************************
VARIABLE ParaCCenter NUMBER

BEGIN
: paraccenter: = 0;
END;
/

CREATE TABLE ccenters
(id NUMBER,
name VARCHAR2 (20).
number base);

INSERT INTO ccenters VALUES(1,'NUST',null);
INSERT INTO ccenters VALUES(2,'SEECS',1);
INSERT INTO ccenters VALUES(3,'NBS',1);
commit;

SELECT * from ccenters
WHERE id IN DECODE(:ParaCCenter, 0, id,)
(SELECT id FROM ccenters
START WITH basic =: ParaCCenter
ID of CONNECTION BY PRIOR = base
UNION
SELECT: ParaCCenter OF double
)
)
/
BEGIN
: paraCCenter: = 1;
END;
/

SELECT * from ccenters
WHERE id IN DECODE(:ParaCCenter, 0, id,)
(SELECT id FROM ccenters
START WITH basic =: ParaCCenter
ID of CONNECTION BY PRIOR = base
UNION
SELECT: ParaCCenter double))
/
The result is
(SELECT id FROM ccenters

ERROR at line 3:
ORA-01427: einreihig subquery returns multiple rows

How this query can be rewritten for the given feature. Any response will be appreciated.

Thank you
Try something like this:
```
SELECT * FROM ccenters
WHERE :ParaCCenter = 0
OR id in
  (SELECT id FROM ccenters
   START WITH base=:ParaCCenter
   CONNECT BY PRIOR id = base
   UNION
   SELECT :ParaCCenter FROM dual
