Update statement Select MAX
Hello guys, small head scratcher here (probably just my mind head)Summary of the issue: Updated between two tables, try to use the rank, will not work.
I took a few of the fields of interest here: -.
CREATE TABLE spell_tags (

How to optimize the update statement so that the query is reading the same table?
Hi all
I have a process with the following UPDATE statement:
Sales_val update
SET ship_date =)
Select max (hist.ship_date)FROM sales_hist hist
WHERE hist. X_ID = A.X_ID
AND hist. X_VAL = A.X_VAL)
) WHERE EXISTS (select * from sales_hist hist where )
WHERE hist. X_ID = A.X_ID
AND hist. X_VAL = A.X_VAL
)
sales_val - 50 lines mln (unique index)
sales_hist - 20 mln ranks (unique index)
I met many problems with waits and locks - how to optimize to avoid locks using the parameters of tables or changes of the declaration? or maybe is there another way to do optimization ?
Kind regards
Bolo
Thank you for that. Collect in bulk Unfortunatelly + FORALL does not work with the types in 10g - solution is to use the FOR loop and is not as effective as FORALL in many cases. I do still some tests to solve this problem - I'll put you once it's done.
EDIT: hash partitioning + fusion - 3-5 minutes (time), so for now it's the solution to the problem. Thank you all for the great discussion!

Solution probably really Simple (where in the Update statement)
Right,
I have a table. In this table, there are 5 fields for the sake of arguments:
COLUMN_ONE COLUMN_THREE COLUMN_FOUR COLUMN_FIVE COLUMN_TWO
On this table there will be duplicate records, but only the column 1, column 2 and 3 on these "duplicate" files will be the same, column 4 will be different (column 4 is not a unique identifier, but if there are duplicate records, it will be different at least 2 records). Column 5 is not yet filled, all null.
I need a way to update column 5 of these duplicate records. However, let me update on one of the folders and the criteria for this will be where column_4 = "Hello".
So far I came with an update statement similar to the following, but I don't know where with her:
UPDATE DANS_TABLE
SET COLUMN_five = "DUPLICATE".
WHERE EXISTS (SELECT column_one | column_two | column_three, COUNT (*))
OF DANS_TABLE
GROUP BY column_one | column_two | column_three
SEEN (COUNT (*) > 1)) and column_four = 'Hello ';
For any help, thank you very much! Much appreciated,
DanThis is the query that updates that one line duplicated to column_five. I hope this helps...
UPDATE DANS_TABLE x 1
SET COLUMN_five = "DUPLICATE".
WHERE THERE ARE
(
Select r_id of
(select max (rowid) r_id, column_one | column_two | column_three)
of DANS_TABLE t1 where exists
(
Select str of
(
SELECT column_one | column_two | column_three str, COUNT (*)
OF DANS_TABLE
GROUP BY column_one | column_two | column_three
SEEN (COUNT (*) > 1)
) t2 where t2.str = t1.column_one | T1.column_two | T1.column_three
) column_one group | column_two | column_three
) x 2 where x 1 .rowid = 2 .r_id x
) and column_four = 'Hello '; -
How can I use multiple row subqueries in update statement
Hai All
I'm using the Group feature in my update statement... and I need to update several lines so I need to use several rows
subquery pls tell me how to use multiple row subqueries in update statement
For example
while I use it like this I got an error
Update dail_att set outtime to (select max (r2.ptime) in the temp_att where empcode = r2.enpno and)
bar code = r2.cardn and group attend_date = r2.pdate by enpno, update, cardn);
Pls tell me how to use for example
Thanks and greetings
Srikkanth.MHello
for r2 loop p1
R2 is a line of the cursor,
Max (R2. PtIMe)? It is always equal to r2.ptime if the select statement returns rows.

Performance issue with the Update statement
Oracle 10204
I have a problem related to updaing one performance table.
only 5000 lines should be updated.
Hir are some details on the tables/M.V concerned:
I tried to run the update with two options:TABLE_NAME LAST_ANALYZED NUM_ROWS SAMPLE_SIZE PS_RF_INST_PROD 1/20/2010 1:14:22 AM 7194402 7194402 BL_TMP_INTRNT 1/27/2010 9:08:54 AM 885445 885445 NAP_INTERNET 1/25/2010 11:47:02 AM 7053990 560777
1. with the plan than oracle choose.
2. with notes I added.
In both cases I he collapsed after more than an hour.
Can any one suggest how to speed it up?

Unfortunately, important updates and selection of optional to install updates gives no information.
Windows Update, you can click on the links "# important updates are available" and "optional updates # are available.
But since I had a few problems with an update some time ago a got help from MS to sort I don't get no information on updates by following these links and the design of the window is not the same as it used to be.Usually there will be a list updates available with code update as "(K477415)" or similar. Now, however, all I see is an empty box with 2 tabs to the left saying Important and optional. The two tabs are clickable, but nothing happens... no list of the updates available on one of them even if he states clearly he doesn't are updates available in both categories.
The only thing I can do is have the update then browse the updates, they are in the section of installed updates and selected those to uninstall. Or simply not install one of them. I can't select or deselect updated as to control those to install because they are not included.
It seems that windows updates is screwed
Try these:

I have a database in my application, and part of it (obviously) will require the user to update the database with the current information.
There are 24 columns of the table, and I have my update function works almost 100%, except that there are two drop downs, and when the user updates the record individual everything that is selected in the fall of two downs, is applied to all records.
My update statement is like this:
var statement:SQLStatement = new SQLStatement();statement.sqlConnection = connection;statement.text = "UPDATE TABLE SET " + "OneFish=?, " + "TwoFish=?, " + "RedFish=?, " + "BlueFish=?, " + // CONTINUES AS TEXT INPUTS DOWN TO "DropDown1=?, " + "DropDown2=?, " + // FEW MORE TEXT INPUTS THEN "WHERE RECORD_ID=?"; statement.parameters[0] = OneFish.text; statement.parameters[1] = TwoFish.text; statement.parameters[2] = RedFish.text; statement.parameters[3] = BlueFish.text; // CONTINUES AS TEXT INPUTS DOWN TO statement.parameters[17] = DropDown1.selectedItem; statement.parameters[18] = DropDown2.selectedItem; // FEW MORE TEXT INPUTS THEN statement.parameters[23] = FishOption.selectedItem.RECORD_ID; statement.addEventListener(SQLEvent.RESULT, updateWorked); statement.addEventListener(SQLErrorEvent.ERROR, updateFailed); statement.execute();
ALL updates day very well and shown to the a specific RECORD_ID. However, the decline in the bottom change overall.
This does not happen on my service of "addFish". Someone out there have any ideas why this is?
Update: It isn't my SQL. If I close the application and then go back, the changes show correctly. The drop down menus are simply not refreshing properly after the update of the database.
J.Rab!
I literally JUST thought out and sat next to the woman to rejoice with the laptop on my lap! Then the BlackBerry made his small notification and I said out loud, "oh look, it's probably somebody tell me what I did wrong before that I could update!
Had dinner and a record label with a look at it to understand.
To display the resulting data & update fields, I was setting the command prompt from the drop down menus! I went my output and changed function use the selectedItem and success!
I also forgot to include a refreshTheDatabase(); at the end of my updateFunction() function call;
I hit a brick wall with this for several hours this afternoon and I can't believe it was that simple! I should have got up and walked away earlier!

Hi friends,
Need your help with an update statement.
Update t set t.icode int_tab =.
(select ac.icode in the ac_tab ac, ed edition
where ac.current_code = ed.unit)
where ed.process_no = t.action_no);
where ed.process_no = t.action_no
*
ERROR on line 4:
ORA-00904: "ED". "" PROCESS_NO ": invalid identifier
Basically, we need to update int_tab.icode with ac_tab.icode where ac_tab.current_code = edition.unit
Thank you very much
I suggest you MERGE. Inside () I call "source" can be controlled carefully. And then you can easily do the UPDATE
No funny Executive plans and if he SELECT jobs, UPDATE works as well.
MERGE into the target int_tab
USING (SELECT t.rowid, rid, ac.icode,
Of ac_tab ac
Join IN-HOUSE ed Edition
ON ac.current_code = ed.unit
Join IN-HOUSE int_tab t
ON ed.process_no = t.action_no
WHERE t.icode! = ac.icode
and t.icode is not null) source
on (target.rowid = source.id)
WHEN MATCHED
THEN UPDATE set target.icode = source.icode;

Please suggest if I'm doing something wrong or it is not possible to update the table like that.
(I know that I can use ForAll Update statement, but I do not want to use Collections here.)
Thank you carine, finally I found my answer,
the update query requires that each record that will be updated should be updated only once. so if I do join 1<->1 it updates successfully.
Thanks to all who contributed, or at least tried. Thanks again.

The statement above sets updated the column equip_stg in WRC if err for corresponding material and reason, there is no line in the REASON_SETUP table.
I want to change the code above so that the validation above is first done with REASON_SETUP according to equipment and column of type of reason. Is there is no line for this type of material and the reason in this table, then he must hit lookup table. Example, I have data from equipment EQP1, status = 3, then it should check if REASON_SETUP has everything save for EQP1 equipment and the reasoning of type 1. If she made the next record should be validated on the table otherwise come file should be validated against the lookup table. For the table of choice also I have same join conditions
STG.equipment_fk = lookup.equipment_pk
AND stg.downtime_reason_code = lookup.reason_code
Thanks in advance.
Kind regards

Hello
I think I see. All lines for each (equipment, reason_type) will be removed completely on a table or another. reason_setup if possible and looking as if this combination never occurs in reason_type. Another way to say it is that you want only (equipment, reason_type) groups of the best tablle, where reason_type is better than search. Exactly what made a Request Top - N . Here's a way to do it:
UPDATE equip_stg
SET err_code = "WRC".
WHERE (equipment, downtime_reason_code) NOT IN
(
WITH union_data AS
(
SELECT 'A' preference AS, reason_code, reason_type, equipment
OF reason_setup
UNION ALL
SELECT equipment, reason_type, reason_code, 'B' AS preferences
SEARCH
)
got_r_num AS
(
SELECT equipment, reason_type, reason_code
DENSE_RANK () (PARTITION BY MATERIAL, reason_type
ORDER OF preference
) AS r_num
Of union_data
)
SELECT equipment
DECODE (reason_type
1, 3
3, 2
)
reason_code
OF got_r_num
WHERE r_num = 1
)
;
To see how this works, reconstruction of the NOT IN subquery, step by step. First run just union_data as a stand-alone application. When you understand what it does, run got_r_num and when you see what he's doing, run the set NOT IN subquery.

I don't know the reason why at first sight, but it is obvious that the inner nested loop was doing a lot of work (full index scan).
My first thought was to rewrite the query in a merge statement.
Perhaps leads to a more effective plan and so no need to delve deeper into the issues you have raised ;-)

The company_id above should be updated as "185994" How do I?
The update below does not work properly., so correct my update statement
UPDATE USR_GRP_PROFILE TO THE TOP OF UP.COMPANY_ID = 185994 SET

AND LOGICAL_COMP.COMPANY_ID = COM. LOGICAL_COMPANY_ID);
Thank you

You're close, you need a where clause clause. Something like:
UPDATE USR_GRP_PROFILE TO THE TOP
SET UP.COMPANY_ID = 185994
where company_id IN (SELECT UP.COMPANY_ID
OF USR_GRP_PROFILE
U OF USERS,
MAP C,
THIS CARD_EXTN,
COM OF THE COMPANY,
COMPANY LOGICAL_COMP
WHERE THIS. STATUS_E_STATEMENT AS 'U '.
AND THIS. CARD_ID = C.CARD_ID
AND U.USER_ID = C.USER_ID
AND U.PROFILE_ID = UPWARD. PROFILE_ID
AND UP.COMPANY_ID = COM.COMPANY_ID
AND LOGICAL_COMP.COMPANY_ID = COM. LOGICAL_COMPANY_ID);

Select Max (Date) in two different tables...
Dear all,
I need the date of last update of two different tables, I mean max (date). We will update one table at a time. Updated once I need to take the last update.
It can be either in table A table B.
for example.
Table A
Date of the ID
100 16/05/2014
101 20/05/2014
102, 22/05/2014
Table B
Date of the ID
100 04/06/2014
101, 26/05/2014
102 21/05/2014
I need the date of table B (101 26/05/2014) last updated date...
Hello
Another way, using much more GRAND:
SELECT LARGER (max1, max2) x
FROM (SELECT MAX (mydate) max1
OF mytable_a
)
(SELECT MAX (myotherdate) max2
OF mytable_b
)
;
Best regards
Bruno Vroman.

Select Max (date) multiple records
I'm having a problem getting the last value for several gauges. Here's my query:
SELECT parameter_id,
TS_ID,
value,
Location_id,
Date_Time
Of
MyTable
JOIN IN-HOUSE
mytable2
WE
TS_ID = ts_id
WHERE
TS_ID LIKE '% - rev.
unit_id = ("pi")
the value IS NOT NULL
Location_id as "xxxx".
Date_Time =
(SELECT Max (date_time)
My TABLE
GROUP BY parameter_id)
;
Hello
A scalar subquery, such as the expression to the right of the sign =
Date_Time = (SELECT...)
must produce (at most) only 1 row. If the subquery produces 2 or more lines, it will trigger an error.
Given that you are using "GROUP BY parameter_id" in the subquery, it will produce a separate line of output for each distinct value of parameter_id. You can use a correlated subquery at that time, that only looks like a parameter_id, or you can use a subquery IN, like this:
WHERE (parameter_id, Date_Time) IN
(
SELECT parameter_id
MAX (date_time)
FROM MyTable
GROUP BY parameter_id
)
I hope that answers your question.
If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
Explain, using specific examples, how you get these results from these data.
