PL/SQL question - 'new' comeback album

Hello

I'm trying to return the last record in a table where a date is less than or equal to a column in the primary table.

I tried to create a sample that allows to explain this... Please bare with me :-)

I have 2 tables and by running the following:

SELECT D.
OF ML_BILLS B
INNER JOIN ML_DETAIL D ON D.SITE_CODE = B.SITE_CODE
AND D.EPISODE_ID = B.EPISODE_ID
AND D.APPT_DATE < = B.BILLL_DTTM
"WHERE BILLL_DTTM = ' 06-SEP-2010.

I get these results

TEST_ID SITE_CODE EPISODE_ID APPT_DATE TEST_CODE1 TEST_CODE2
1 CCH 12345678 01/09/2010 TEST1 TEST2
2 CCH 12345678 05/09/2010 ML1 ML2
8 Jacqueline 765 BOY 66666666 03/09/2010
9 BOY 66666666 06/09/2010 5454 212121

I want only to return 2 test_id and 9 - who are the last appt_dates for each episode_id - which meets the < = September 6 criteria.

I started working on something - see below, but it is a way just to go

SELECT D.
OF ML_BILLS B
INNER JOIN (SELECT MAX (APPT_DATE), MAX_DATE,
SITE_CODE,
EPISODE_ID
OF ML_DETAIL
"WHERE APPT_DATE < = ' 06-SEP-2010.
SITE_CODE GROUP,
EPISODE_ID) MAXDETAIL ON D.SITE_CODE =
MAXDETAIL. SITE_CODE
AND D.EPISODE_ID =
MAXDETAIL. EPISODE_ID
AND D.APPT_DATE =
MAXDETAIL. MAX_DATE

If anyone can help that would be great :-)

Hope it makes sense

See you soon

Mark

Hello

Here's a way to do it:

WITH     got_r_num     AS
(
     SELECT      D.*
     ,     RANK () OVER ( PARTITION BY  d.episode_id
                      ORDER BY          d.appt_date     DESC
                    )     AS r_num
     FROM          ML_BILLS      B
     INNER JOIN      ML_DETAIL      D      ON      D.SITE_CODE      = B.SITE_CODE
                                       AND         D.EPISODE_ID      = B.EPISODE_ID
                                       AND      D.APPT_DATE      <= B.BILLL_DTTM
     WHERE      BILLL_DTTM     = TO_DATE ( '06-SEP-2010'
                           , 'DD-MON-YYYY'
                           )
)
SELECT     *     -- or list all columns except r_num
FROM     got_r_num
WHERE     r_num     = 1
;

If billl_dttm is a DATE, then do not compare to a sttring, such as ' 06 - SEP - 2010 "." Always compare it to another DATE, like the vlue returned by TO_DATE.

Hello
PL/SQL insert new string in the string specified to a specific Position
Continuing the previous thread has answered, I would like to know how to cut the data after the underscore ("_").
Example:
Old chain: D100_RT

Here after, what is there after that execution should be deleted.
Thank you

Suppose that the string = D100_RT

the basic sql question

Hi all I have a basic sql question
Watch below two querries

1.  select 1 from dual where 1 in (select 1 from dual union all select null from dual) 

It gives output  as 1

but below one 

2.   select 1 from dual where 1 not in  (select 2 from dual union all select null from dual)

It gives output as no data found

I think as operator will not compare with all the values, but not the outcome it will compare with all values... When comparing with the value null, the result is automatically null

I'm wrong
Please help me on this

and why performance wise in operator is more better than no of?

Thanks to all in advance

New Smart Album PSE9 Mac OSX problems

I am running PSE9 on a Macbook Pro and Imac, both using Mac OS x. creating a new Smart Album on the Macbook works perfectly, but on the Imac, it is impossible. When I try to create a new Smart Album I just get a spinning ball and everything stops. I uninstalled PSE9 and the organizer and also removed any trace of them in the library. Their Setup again and make sure that I import images of only a dozen in organizer makes things a little better. This time the spinning ball lasted for a minute and then I could create smart albums. I then tried to create another Smart Album and had the ball rotates for a few minutes. Creation of the Smart Album has been even worse. There is no problem with the normal albums.
Someone has a way to turn it. I have about 9000 images, dating back to 2001, and I want to set annual records for smart Albums are a very useful tool.
A similar request by another Member some time ago received no feedback.
Thanks for any help.

I use OS x 10.8.2. Your solution works perfectly - thanks.

I still don't see why the smart albums do not work on my iMac while it works on my Macbook Pro. If anyone has an idea please let me know.

I'll give this discussion a few days and then close it.

Thank you

Thank you.

Using this SQL statement, you can get this list:

                                      )
                         FROM DUAL))

It is a question of SQL and has nothing to do with the Apex.

SQL question on natural joins

I am a newbie to SQL and I studied the book of Fundamentals SQL Server Oracle OCA 12 c, but a section on natural joins to confuse me.
Basically, the author says:
SELECT r.region_name, d.department_name, l.city, c.country_name
DEPARTMENTS d
NATURAL JOIN places l, c countries, regions r;
The natural join between DEPARTMENTS and LOCATIONS creates a provisional result, consisting of 27 lines since they are implicitly attached on the column of location_id. This set is then Cartesian-joined to the table of the COUNTRY as a join condition is not implicitly or explicitly specified. 27 interim lines are attached to 25 lines in the COUNTRY table, which gives a new temp results set with 675 (27 × 25) rows and three columns: DEPARTMENT_NAME, CITY and COUNTRY_NAME. This set is then attached to the REGION table. Once more, a Cartesian join occurs because column REGION_ID is absent from any join condition. The final result set contains rows and four columns (675 × 4) 2700.
I can understand because you evaluate joins from the left. But then he wrote:
The JOIN... USE and JOIN... ON the syntaxes are better suited to join multiple tables. The following query joins four tables using the natural join syntax:
SELECT country_id region_id, c.country_name, l.city, d.department_name
DEPARTMENTS d
NATURAL JOIN places l
NATURAL JOIN country c
NATURAL JOIN region r;
This query generates correctly 27 lines in the final results set since the required join columns are listed in the SELECT clause. The following query illustrates how the JOIN... CLAUSE is used to extract the same 27 lines. A join condition can reference columns only in its scope. In the following example, the join of DEPARTMENTS slots can not reference columns in the COUNTRIES or REGIONS of tables, but the join between the COUNTRIES and REGIONS may refer to any column of four tables involved in the query.
This second method of the part of the natural writing joined confuses me. I don't understand the logic behind the 2nd series of States of Natural Join. For me, it seems that the first series and the 2nd set look alike, but they are apparently not.
Can someone tell me the differences?
Thank you!!

Hello

The more important thing to learn more about NATURAL JOIN is: never use it. If you add new columns, joins can get different results. I've never heard of someone uisng NATURAL JOIN apart from a manual or a question like yours.

There are a lot of things in Oracle that take the time to learn and are useful. All the time you spend learning things is better spent on them.

Some SQL questions.
Hello friends,

I have a few questions.
1. what sql statement returns the name and the maximum size of the data file in the database?
2. how to find the location of the trace files database using the data dictionary?
3. which database view and column shows the number of validations has done a user session?
4. How do you change the oracle default database block size, without recreating the database?

5 What is poorly stated or right, so bad... that is wrong with this query.
SELECT column1 from tableABC including NOT IN (select Column1 from tableXYZ);

6. What is the most effective way to write this statement?
7. How do you determine that the new application is more effective than the original query?
Hello

+ 1. What sql statement returns the name and the maximum size of the data file in the database? +

SELECT file_name, bytes
FROM dba_data_files
WHERE IN (SELECT MAX (bytes) bytes
FROM dba_data_files)

+ 2. How to find the location of the trace files database using the data dictionary? +
With the help of the parameter $ v

For example, select name, value of the parameter $ v
WHERE name like ('% dest');

3. which database view and column shows the number of validations has done a user session?

+ 4. How to change the size of the oracle default database block, without re-creating the database? +

Database block size is not editable once database created, however depending on your version, do you use
block of different size avaiable in oracle version db_4k_cache_szie, db_8K_cache_size (not if your default block size is 8K), db_16k_cache_size

+ 6. What is the most effective way to write this statement? +
7. How do you determine that the new application is more effective than the original query?

EXPLAIN_PLAN running on query and analysis cost timing. Simply also check how long it took the request to return the result;), the formula gross to discover the effective application

Concerning

During the migration of projects opening in PICTURES project names will appear on the News Photos 'albums '?

Prepare my Aperture library (with deep levels of files/projects/albums) to migrate to pictures. I want to know if the NAMES of my files/projects/albums will be kept in Photos and will appear in the new view of photo albums.

Using Aperture 3.6 and pictures is up to date. 10.11.6 OSX

Yes, they migrate. To more easily confirm everything is fine select see the sidebar on the view menu. Also, your current Aperture library will remain unchanged during the migration, if youre not really take risks by trying.

Question PSE 14 Album organization?

Hello
I'm new to PES. I have a problem when I take pictures from the organizer and put in an Album. Everything what I see online that I should be able to move and organize my photos. The tutorials online to show every inch nail has space between them and you can move them. My albums, I'm trying to create, the photos are all close together, and I can't do anything with them, very frustrating. I have tried for days to figure out but must be missing something. Can you please help.
Thank you
Scott

Hi Jon

Ya that's what I did, if I click once it just starts to do something dashed as if I was preparing a harvest on a photo. Then I click twice and I'll get the circle with a line in it as if she will allow me to drag and drop, but when I drop it, it disappears and nothing changes, almost it as a lock on it. Totally weird. I had my friends computer watch and they look up and follow the instructions, but in vain.

SQLDev 4.1 ai2 - problem with connection SSO to SQL Server (new)

I am trying to connect to SQL Server with the new version. I have the jtds 1.3 installed and get the configuration of SQL Server tab, but once more to get the infamous SSO error trying to connect:
Status: Failure-i/o Error: failure of the SSO: library Native SSPI has not loaded. Check the system java.library.path property.

I tried to copy ntlmauth.dll in several places:
C:\Oracle\sqldeveloper4.1\sqldeveloper\sqldeveloper\bin
C:\Oracle\sqldeveloper4.1\sqldeveloper\jdk\jre\bin
C:\Oracle\sqldeveloper4.1\sqldeveloper\jdk\jre\
C:\Oracle\sqldeveloper4.1\sqldeveloper\jdk\
Given SQLDev running, but still get the error of SSO.

Discovered this problem (thanks to Jeff Smith!). I had a 32-bit DLL in the path that are in conflict with the 64 bit one. Once I deleted all of the extra 32-bit versions, the SSO authentication works.

Hi, Mustafa,

Sorry, I don't know anything about SQL Developer.

SQL * PLUS connects with SQL > question

People,
I'm confused on the command. / sqlplus with Oracle database.
According to my understanding,. / sqlplus connected with SQL > using option 3: sysdba, sysoper, sysasm.
I connect with SQL > to run the rel853.sql script to create a table PSOPRDEFN but a field "OPERPSWDSALT" did not appear in the table PSOPRDEFN although it is in the Create Table statement.
I connect with SQL * in the directory/home/user/OracleDB_Home/bin as below:

$ export SYSTEM_PASS = AccessId/mypass
$ export ORACLE_HOME = / home/user/OracleDB_Home
$ export ORACLE_SID = HRCS90
$. / lsnrctl start LISTENER
$. / AccessId/mypass sqlplus as sysdba
SQL > startup
SQL > @/opt/PT8.53/scripts/rel853.sql
SQL > select OPERPSWDSALT in the AccessId.PSOPRDEFN;
It returns: "OPERPSWDSALT": invalid identifier.

I checked the table PSOPRDEFN that the OPERPSWDSALT field did not appear in the table PSOPRDEFN.
I tried the sysoper option as below:
$. / sqlplus AccessId/mypass as sysoper
SQL > startup
SQL > @/opt/PT8.53/scripts/rel853.sql
SQL > select OPERPSWDSALT in the AccessId.PSOPRDEFN;
It returns: "OPERPSWDSALT": invalid identifier.
The sysoper error is the same thing with sysdba error.
I tried the sysasm option as below:
$. / sqlplus AccessId/mypass as sysasm
He returned: connection refused.

Someone told me this connection as SYS causes this error. If not a sysdba, sysoper, or sysasm, use the command. / sqlplus AccessId/mypass cannot connect with SQL >.

My question is:

First of all, why is what OPERPSWDSALT did not appear in the PSOPRDEFN table while it is in the CREATE TABLE statement?

Seocond, if not use SYS which is one of the 3 options, how to run the command. / sqlplus AccessId/mypass to connect with SQL > so that CREATE TABLE PSOPRDEFN correctly?
Thank you.

People,

Hello. Thanks much for the reply. I just do the commands below:

$ export SYSTEM_PASS = AccessId/mypass

$ export ORACLE_HOME = / home/user/OracleDB_Home

$ export ORACLE_SID = HRCS90

$. / lsnrctl start LISTENER

$. / AccessId/mypass sqlplus as sysdba

SQL > show user;

Its release: the USER is "SYS".

SQL > connect AccessId/mypass

Its output:

Error: ORA - 01034:ORACLE not available

ORA-27101: shared memory realm does not exist

64 - Linux_x86 error: no such file or directory.

As we see above, unable to connect to the Oracle database AccessId.

My question is:

What to do on AccessId, so that it can connect to the Oracle database?

Thank you.

so much for the use that you refuse to actually use COPY it PASTE & so that we can see the whole session.

In the past, you did

> SQL > startup

Maybe the database is out of order & must be started.

do exactly as below (line by line)

ID

sqlplus

/ as sysdba

startup

connect AccessId/mypass

COPY the results from above then PASTE all back here

running of SQL question
Hi expert,

When I ran after SQL, error message reads "table or view does not exist" pointing to the table "dba_tab_cols" and "dba_all_tables". There is no other question for this statement, because if I changed table "user_tab_cols" and "user_all_tables", it works well.

declare
v_old_table DBA_tab_columns.table_name%type;
v_where Varchar2 (4000);
Boolean v_first_col: = true;
type rc is ref cursor;
c rc;
v_rowid varchar2 (20);
Val varchar2 (50): = "Test note";

Start
for r in)
Select
t.*
Of
dba_tab_cols t, dba_all_tables a
where t.table_name = a.table_name
and t.data_type like '% CHAR % '.
and a.owner = 'QA'
order by t.table_name loop)

If v_old_table is null then
v_old_table: = r.table_name;
end if;

If v_old_table <>r.table_name then
v_first_col: = true;

-dbms_output.put_line ('search' | v_old_table);

Open c for ' select rowid from ' ' |. ' v_old_table | '" ' || v_where;

extract the c in v_rowid;
loop
When the output c % notfound;
dbms_output.put_line (' rowid: ' | v_rowid |) "in" | v_old_table);
extract the c in v_rowid;
end loop;

v_old_table: = r.table_name;
end if;

If v_first_col then
v_where: = 'where ' | r.column_name | "as" %' | Val | '%''';
v_first_col: = false;
on the other
v_where: = v_where | "or" | r.column_name | "as" %' | Val | '%''';
end if;

end loop;
end;

But if I choose these DBA tables in the toad sql Editor, it works well, I am currently using my own credentials, not the administrator credentials. why he get different effects running in these two ways?

Thank you very much

You answered your own question - you know that you have the administrator privileges when you
Open a session under your own credentials - but your id user obviously does TOAD.

You use SQL * for the query that fails?

BTW, you do not give us your version of Oracle - you must always tell us what it is

Please read the forum FAQ and also the thread "sticky" by BluShadow at the top of the list of positions
