Metadata: Filter By Update State

If your file has been modified externaly or by another LR catalog, you will notice that LR recognize them and let you choose these option :
Metadata File Needs To Be Updated
Metadata Was Changed Externally
Error Saving Metadata
If you have a lot of pictures, this is not simple to find only the modified files. You can select all files and click the update button, but then the entire pictures will be scanned and somehow rewritten (jpg, xmp, ...), this process is too unfriendly.
Filtering the picture by the state of the metadata would be really simple and fine when working with more than one catalog, computer or software.

Flash,
This is a much needed feature that I some time ago sent in a feature request. A new feature request might be in order - you can file one at https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform if you would like.

Thank you all for the great ideas, you have been extremely helpful. Here is what we did and were able to resolve the query.
We started with Etbin's idea to create a table from the ext table so that we can index and reference easier than an external table, so we did the following:
SQL> create table ext_person as select P_ID,ED_ID,trim(F_NAME) fst_name,trim(L_NAME) lst_name from EXT_NAMES_CSV;
Table created.
SQL> desc ext_person
Name                                                                                Null?    Type
P_ID                                                                                         NUMBER
ED_ID                                                                                        NUMBER
FST_NAME                                                                                     VARCHAR2(300)
LST_NAME                                                                                     VARCHAR2(300)
SQL> select count(*) from ext_person;
COUNT(*)
     93383
SQL> CREATE INDEX EXT_PERSON_ED ON ext_person (P_ID,ED_ID) TABLESPACE D_INDEX;
Index created.
SQL> exec dbms_stats.gather_index_stats(ownname=>'APPD', indname=>'EXT_PERSON_ED',partname=> NULL , estimate_percent=> 30 );
PL/SQL procedure successfully completed.We had a look at the plan with the original SQL query that we had:
SQL> explain plan for update temp_person
2 set first_name = (select fst_name
3                    from ext_person
4                               where temp_person.PERSON_ID=ext_person.p_id
5                               and   temp_person.DISTRICT_ID=ext_person.ed_id);

20 rows selected.As you can see the time has dropped to 37min (from 6 hrs). Then we decided to change the SQL query and use donisback's suggestion (using MERGE); we explained the plan for teh new query and here is the results:
SQL> explain plan for MERGE INTO temp_person t
2 USING (SELECT fst_name ,p_id,ed_id
3 FROM ext_person) ext
4 ON (ext.p_id=t.person_id AND ext.ed_id=t.district_id)

6 UPDATE set t.first_name=ext.fst_name;

Performance Issue: Update Statement

Hi Team,
My current environment is Oracle 11g Rac...
My application team is executing a update statement (ofcourse it is there daily activity) ...
updating rows of 1 lac, daily it takes about 3-4 minutes to run the statement.
But today its taking more time i.e more than 8 hours.
then I have generated the explain plan of the update statement and found that its taking full table scan.
Kindly assist me in fixing the issue by letting me know where and how to look for the problem.
**Note: Stats gather is updated
Thanks in advance.
Regards

If you notice there are no indexes to the below update statement -

Hi Gokul,
in case of no statistics most likely the optimizer would do a dynamic sampling, so ironically, no statistics is often better than statistics.
It could be that some of the tables is used as a temp table (i.e. is filled with data to carry out some operations, and then purged), in which case the stats job could've caught it when it was empty. But even if the cardinalities would have been fine, I don't really think the optimizer has a lot of options with the query as is stands, because the aggregate subqueries restrict the ability of the optimizer to apply query transforms.
Still, worth a shot to check if stats are accurate -- that's an easy thing to do and couldn't possibly do any harm.
Best regards,
Nikolay

Update statement takes too long to run

Hello,
I am running this simple update statement, but it takes too long to run. It was running for 16 hours and then I cancelled it. It was not even finished. The destination table that I am updating has 2.6 million records, but I am only updating 206K records. If add ROWNUM <20 to the update statement works just fine and updates the right column with the right information. Do you have any ideas what could be wrong in my update statement? I am also using a DB link since CAP.ESS_LOOKUP table resides in different db from the destination table. We are running 11g Oracle Db.
UPDATE DEV_OCS.DOCMETA IPM
SET IPM.XIPM_APP_2_17 = (SELECT DISTINCT LKP.DOC_STATUS
FROM [email protected] LKP
WHERE LKP.DOC_NUM = IPM.XIPM_APP_2_1 AND
IPM.XIPMSYS_APP_ID = 2
WHERE
IPM.XIPMSYS_APP_ID = 2;
Thanks,
Ilya

In the first SQL, the SELECT against the remote table was a correlated subquery. the 'WHERE LKP.DOC_NUM = IPM.XIPM_APP_2_1 AND IPM.XIPMSYS_APP_ID = 2" means that the subquery had to run once for each row of DEV_OCS.DOCMETA being evaluated. This might have meant thousands of iterations, meaning a great deal of network traffic (not to mention each performing a DISTINCT operation). Queries where the data is split between two or more databases are much more expensive than queries using only tables in a single database.Sorry to disappoint you again, but with clause by itself doesn't prevent from "subquery had to run once for each row of DEV_OCS.DOCMETA being evaluated". For example:

Update statement taking too long to execute

Hi All,
I'm trying to run this update statement. But its taking too long to execute.
    UPDATE ops_forecast_extract b SET position_id = (SELECT a.row_id
        FROM s_postn a
        WHERE UPPER(a.desc_text) = UPPER(TRIM(B.POSITION_NAME)))
        WHERE position_level = 7
        AND b.am_id IS NULL;
        SELECT COUNT(*) FROM S_POSTN;
        214665
        SELECT COUNT(*) FROM ops_forecast_extract;
        49366
SELECT count(*)
        FROM s_postn a, ops_forecast_extract b
        WHERE UPPER(a.desc_text) = UPPER(TRIM(B.POSITION_NAME));
575What could be the reason for update statement to execute so long?
Thanks

What could be the reason for update statement to execute so long?You haven't said what "too long" means, but a simple reason could be that the scalar subquery on "s_postn" is using a full table scan for each execution. Potentially this subquery gets executed for each row of the "ops_forecast_extract" table that satisfies your filter predicates. "Potentially" because of the cunning "filter/subquery optimization" of the Oracle runtime engine that attempts to cache the results of already executed instances of the subquery. Since the in-memory hash table that holds these cached results is of limited size, the optimization algorithm depends on the sort order of the data and could suffer from hash collisions it's unpredictable how well this optimization works in your particular case.
You might want to check the execution plan, it should tell you at least how Oracle is going to execute the scalar subquery (it doesn't tell you anything about this "filter/subquery optimization" feature).
Generic instructions how to generate a useful explain plan output and how to post it here follow:
Could you please post an properly formatted explain plan output using DBMS_XPLAN.DISPLAY including the "Predicate Information" section below the plan to provide more details regarding your statement. Please use the {noformat}[{noformat}code{noformat}]{noformat} tag before and {noformat}[{noformat}/code{noformat}]{noformat} tag after or the {noformat}{{noformat}code{noformat}}{noformat} tag before and after to enhance readability of the output provided:
In SQL*Plus:
SET LINESIZE 130
EXPLAIN PLAN FOR <your statement>;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);Note that the package DBMS_XPLAN.DISPLAY is only available from 9i on.
In 9i and above, if the "Predicate Information" section is missing from the DBMS_XPLAN.DISPLAY output but you get instead the message "Plan table is old version" then you need to re-create your plan table using the server side script "$ORACLE_HOME/rdbms/admin/utlxplan.sql".
In previous versions you could run the following in SQL*Plus (on the server) instead:
@?/rdbms/admin/utlxplsA different approach in SQL*Plus:
SET AUTOTRACE ON EXPLAIN
<run your statement>;will also show the execution plan.
In order to get a better understanding where your statement spends the time you might want to turn on SQL trace as described here:
When your query takes too long ...
and post the "tkprof" output here, too.

Bulk SQL Update Statements

I need to perform bulk updates on my tables using SQL. The tables are really very big and most of updates occur on couple of million records. As such the process is time consuming and very slow. Is there anything I could do to fine tune these update statements? Please advise. Some of the same SQL statements I use are as follows
update test set gid=1 where gid is null and pid between 0 and 1;
update test set gid=2 where gid is null and pid between 1 and 5;
update test set gid=3 where gid is null and pid between 5 and 10;
update test set gid=4 where gid is null and pid between 10 and 15;
update test set gid=5 where gid is null and pid between 15 and 70;
update test set gid=6 where gid is null and pid between 70 and 100;
update test set gid=7 where gid is null and pid between 100 and 150;
update test set gid=8 where gid is null and pid between 150 and 200;
update test set gid=9 where gid is null and pid between 200 and 300;

Decode function in Update statement

Hello everyone,
I'm trying to write a query where I can update a pastdue_fees column in a book_trans table based on a difference between return_dte and due_dte columns.
I am using Oracle SQL. This is what I have so far for my decode function:
SQL> SELECT
2 DECODE(SIGN((return_dte - due_dte)*2),
3 '-1', '0',
4 '1', '12', 'Null')
5 FROM book_trans;
DECO
Null
12
Null
0
So the logic is that if the sign is -1, the value in return_dte column should be 0; if it's +1 then it's 12 and everything else is Null.
So now, I need to enter my decode function into the update statement to update the columns. However, I get error messages.
The logic should be:
UPDATE book_trans SET PastDue_fees = decode(expression)
I've given it a couple of different tries with the following results:
SQL> UPDATE book_trans
2 SET pastdue_fees = SELECT
3 DECODE(SIGN((return_dte - due_dte)*2),
4 '-1', '0',
5 '1', '12', 'Null')
6 FROM book_trans;
SET pastdue_fees = SELECT
ERROR at line 2:
ORA-00936: missing expression
SQL> UPDATE book_trans
2 SET pastdue_fees =
3 DECODE(SIGN((return_dte - due_dte)*2),
4 '-1', '0',
5 '1', '12', 'Null')
6 FROM book_trans;
FROM book_trans
ERROR at line 6:
ORA-00933: SQL command not properly ended
Any help or tips would be greatly appreciated as I've been taking SQL for about six weeks and not very proficient!
Thanks!

Thanks!If you really really really want to update the entire table, the syntax would be...
UPDATE book_trans
SET
pastdue_fees = DECODE(SIGN((return_dte - due_dte)*2), -1, 0, 1, 12, Null);I took out all the single quotes. If you actually have a string column and you're storing entirely numbers in it then it should be declared as a NUMBER column and not a character (varchar2) column.
ALWAYS use the proper data type, it'll save you a ton of headaches in the future.
Also, since you're new to the forum, please read the FAQ so you learn the etiquette and what not.

Unable to execute an update statement using CallableStatement

Hi there,
I'm trying to run an update statement from JUnit using java.sql.CallableStatement and oracle.jbo.server.DBTransaction.
        String updateSql =
            "update footable set barcol=TO_DATE('12-SEP-09','dd-MM-yy') where bazcol = 505";

Is their any limit on the number of column updates in a update statement!

Hello All,
Is their any limit on the number of columns to set in a single update statement.+
am using oracle 11g .
example :-
UPDATE FMLY SET as_comp1 = v_as_comp1 , as_comp2 = v_as_comp2, as_comp3 = v_as_comp3, as_comp4 = v_as_comp4 , as_comp5 = v_as_comp5 , perslt18 = v_perslt18 , persot64 = v_persot64 , fam_size = v_fam_size , numchild = total_children , C_AGE1 = v_c_age1, C_AGE2 = v_c_age2, C_AGE3 = v_c_age3, C_AGE4 = v_c_age4 WHERE FAMID = fmly_famid(i) ;
and also is it good practice to issue single update or multiple updates ?
example for the above update i can have multiple statements like .. does the performance matters if so which is good
UPDATE FMLY SET as_comp1 = v_as_comp1 , as_comp2 = v_as_comp2, as_comp3 = v_as_comp3, as_comp4 = v_as_comp4 , as_comp5 = v_as_comp5
WHERE FAMID = fmly_famid(i) ;
UPDATE FMLY SET perslt18 = v_perslt18 , persot64 = v_persot64 , fam_size = v_fam_size
WHERE FAMID = fmly_famid(i) ;
UPDATE FMLY SET numchild = total_children WHERE FAMID = fmly_famid(i) ;
UPDATE FMLY SET C_AGE1 = v_c_age1, C_AGE2 = v_c_age2, C_AGE3 = v_c_age3, C_AGE4 = v_c_age4 WHERE FAMID = fmly_famid(i) ;

If you can do it in a single SQL statement then you should do that.
Here's a mantra that I found to work out pretty good:

Error while schedulingg update stat in db13

Dear Experts,
Please look into my issue we are facing an error while scheduling update statistics in db13 and I tried to open detailed log
It is given
SXPG_COMMAND_EXECUTE failed for BRTOOLS - Reason: program_start_error: For More Information, See SYS
Please help me how to solve this my error
Regards

Hi,
Check the owner for BRBACKUP, BRARCHIVE, and BRCONNECT in kernel,
these files should be with SIDADM, if not change the owner to SIDADM and rerun the update stats.
and also Refer the note 446172

How do I pass multiple values from a text box to an update statement

I hope this does not sound to lame. I am trying to update multiple values Like this:
Code|| Computer Desc || Computer Price || Computer Name
SEL1 || Apple macbook || 1564 || Apple Macbook Basic
SEL2 || Dell 630 || 1470 || Dell Latitude
I want to change all six values at once in one update statement based on the Code, I can't find a good tutorial/example to help me.
Can anyone point me in the right direction?
Thanks so much,
Laura

You can do conditional updates with decode or case statements e.g.
SQL> create table t as
2 select 'SEL1' as code, 'Apple macbook' as comp_desc, 1564 as comp_price, 'Apple Maxbook Basic' as comp_name from dual union
3 select 'SEL2', 'Dell 630', 1470, 'Dell Latitude' from dual
4 /
Table created.
SQL>
SQL> update t
2 set comp_desc = CASE code WHEN 'SEL1' THEN 'Test1' Else 'Test2' END,
3      comp_price = CASE code WHEN 'SEL1' THEN 1234 Else 2345 END,
4      comp_name = CASE code WHEN 'SEL1' THEN 'Test1 Name' Else 'Test2 Name' END
5 /
2 rows updated.
SQL>
SQL> select * from t
2 /
CODE COMP_DESC     COMP_PRICE COMP_NAME
SEL1 Test1               1234 Test1 Name
SEL2 Test2               2345 Test2 Name

Ask Tom has very good discussion about this, if UPDATE does not work for PK issue, you can use MERGE

Running an update statement on two dependent attributes

Dear All,
I have a repair_job table that contains values for work_cost, parts_cost and total_cost which is the sum of the work and parts cost values. I want to run an update statement that doubles the work cost and, naturally, updates the value of total cost as well. I tried to run it as:
update repair_job
set work_cost = 2 * work_cost, total_cost = work_cost + parts_cost
where licence in (
select licence from car
where year = to_char(sysdate,'YYYY')
thinking that because the update of work_cost is first on the list, the updated value of total cost would be correct. It seems however that the update of total cost happens first and then the work cost is been updated; not sure what the reason is for that and it happens no matter what the order is in the update statement.
I know that I can do it in two separate statements, or use a trigger or PL/SQL to do it but I am curious as to why it has this behaviour. Also, is there a way to do it in a single SQL statement - i.e. forcing the update of the work_cost attribute first and then that of total_cost?
I look forward to hearing from you soon.
Regards,
George

The update to all columns of the row happen at the same time - there is no order involved.
You don't need two statements but you do need to do the updates based on the current value of the columns.
set work_cost = 2 * work_cost, total_cost = 2 * work_cost + parts_cost----------
In addition to sb92075's comments in 11 g you could also just define a virtual column for total_cost and then just query it like you do now.
total_cost NUMBER GENERATED ALWAYS AS (work_cost + parts_cost) VIRTUAL,See this Oracle-base article for an example
http://www.oracle-base.com/articles/11g/virtual-columns-11gr1.php
Edited to supplement sb92075's reply by mentioning virtual columns

How can i use multiple row subquery in update statement

Hai All
I using group function in my update statement.. and i need to update more rows so i need to use multiple row
subquery pls tell me how to use multiple row subquery in update statement
For example
while i am using this like this i got an error
update dail_att set outtime in (select max(r2.ptime) from temp_att where empcode=r2.enpno and
barcode=r2.cardn and attend_date=r2.pdate group by enpno,pdate,cardn);
Pls tell me how to use with example
Thanks & regards

Hai Man
Thanks for ur response Let me clear what i need
First step Fetch the records as text file and stores into table T1
and the next step is i have seperated the text using substring and stores in different columns of a table
There are two shifts 0815 to 1645 and 1200 and 2000
Here I rep IN and O rep OUT
Empno date time inout
001 01-01-10 0815 I
002 01-01-10 0815 I
003 01-01-10 0818 I
001 01-01-10 1100 0
001 01-01-10 1130 I
002 01-01-10 1145 0
002 01-01-10 1215 I
004 01-01-10 1200 I
005 01-01-10 1215 I
004 01-01-10 1315 O
004 01-01-10 1345 I
001 01-01-10 1645 0
002 01-01-10 1715 0
003 01-01-10 1718 0
004 01-01-10 2010 0
005 01-01-10 2015 0
This is my T1 table i have taken data from text file and stored in this table from this table i need to move data to another table T2
T2 contains like this
Empno Intime Intrin Introut Outtime Date
001 0815 1100 1130 1645 01-01-10
002 0815 1145 1215 1715 01-01-10
003 0818 1718 01-01-10
004 1200 1315 1345 2010 01-01-10
005 1215 2015 01-01-10
This what i am trying to do man but i have little bit problems Pls give some solution with good example
And my coding is
declare
     emp_code varchar2(25);
in_time varchar2(25);
out_time varchar2(25);
Cursor P1 is
Select REASON,ECODE,READMODE,EMPD,ENPNO,FILL,PDATE,PTIME,INOUT,CARDN,READERN
From temp_att
group by REASON,ECODE,READMODE,EMPD,ENPNO,FILL,PDATE,PTIME,INOUT,CARDN,READERN
ORDER BY enpno,pdate,ptime;
begin
     for r2 in p1 loop
declare
bar_code varchar2(25);
begin
select barcode into bar_code from dail_att where empcode=r2.enpno and attend_date=r2.pdate;
For r3 in (select empcode,empname,barcode,intime,intrin,introut,addin,addout,outtime,attend_date from dail_att)loop
if r2.inout ='O' then
update dail_att set outtime =(select max(r2.ptime) from temp_att where empcode=r2.enpno and barcode=r2.cardn and attend_date=r2.pdate group by r2.cardn,r2.enpno,r2.pdate );
end if;
end loop;
exception
     when no_data_found then
     if r2.inout ='I' then
               insert into dail_att(barcode,empcode,intime,attend_date)(select r2.cardn,r2.enpno,min(r2.ptime),r2.pdate from temp_att group by r2.cardn,r2.enpno,r2.pdate );
     end if;
end;
end loop;
commit;
     end;
Pls tell me what correction i need to do i the update statement i have used a subquery with group function but when i used it will return only one row but my need is to return many rows and i need to use multiple row subquery
and how can i use it in the update statement
Thanks In Advance
