Hint in Update or Select Statement in an inline query ??

Hi ,
I had an update statement that will get the data from the inline select statement,now where can i can keep the hint ,either in update statement or in Select statement...
Please let me know if my sample script is wrong or any better way to approach...Please assume that Salary table had millions of employee's salary records.
update emp
set salary = salary + (select /*+ full(a) parallel(a,4) */ salary from Salary
where experience > 5 and empno = 55 )
where empno = 85Thanks

You would put the hint in the select statement as you have it, but it won't work until you alias your table name to "a" since that is how you are referencing it in the hint:
update emp
set salary = salary + (select /*+ full(a) parallel(a,4) */ salary from Salary a
where experience > 5 and empno = 55 )
where empno = 85
NOTE I added the "a" right after the Salary table name AND you can only do parallel updates on partitioned table, but the select will run in parallel to at least get the data for you quickly.
To answer your other question about syntax, it is incorrect and there are a lot of ways to write it but a straight forward way would be to use the merge statement
merge into emp e
using (select /*+ full(s) parallel(s,4) */ s.salary from salary s where s.experience > 5) s
on (e.empno = s.empno)
when matched then update
set salary = s.salary;

The better approach would be to determine why you need a hint in the first place. If you're using a hint, that implies that the optimizer is choosing the incorrect plan when left to its own devices. That, in turn, implies that the statistics on your objects, the statistics on your system, your optimizer parameters, your session's optimizer settings or some other variable is incorrect. You're generally better off fixing the root problem than hinting every query.
In this specific case, the parallel hint is invalid because there is no table aliased A. The full hint is invalid for similar reasons. Plus, with the query you provided, if A was intended to be the SALARY table, it seems exceptionally unlikely that you really want to do a full scan on the salary table to look for what had better be a single row (otherwise your query would throw a "too many rows returned" exception).

Use of the "updlock" hint with update and insert statements

I have inherited some stored procedures and am trying to figure out why the developers decided to use the "updlock" hint on many of the update and insert statements. I have looked around everywhere and have found only one explanation of why "update...with
(updlock)" can be useful, namely when a table has no clustered index:
http://www.sqlnotes.info/2012/10/10/update-with-updlock/ I have found nothing yet that mentions why "insert into...with (updlock)" might be used. I understand why the hint
might be useful on select statements in some cases, but if all of the tables have clustered indexes, is there any good reason to use it on update and insert statements?
Thanks,
Ron

This form of deadlock error can occur on a table which has a clustered index.
If you are doing updates on a table which has a clustered index and that table also has a nonclustered index and the nonclustered index is used to find the row to update you can see this type of deadlock. For example create a table with a clustered
primary key index and a nonclustered index by running
Create Table Foo(PK int primary key identity, OtherKey varchar(10), OtherData int);
go
Insert Foo Default Values;
go 10000
Update Foo Set OtherKey = 'C' + Cast(PK As varchar(10))
Create Unique Index FooIdx On Foo(OtherKey);
That creates a table with 10000 rows, a clustered index and a nonclustered index. Then run
Begin Transaction
Update Foo Set OtherData = 1 Where OtherKey = 'C5'
That will use the FooIdx index to find the row that needs to be updated. It will get a U lock on the index row in the FooIdx index, then an X lock on the row in the clustered index, update that row, then free the U lock on FooIdx, but keep the X lock
on the row in the clustered index. (There is other locking going on, but to simplify things, I'm only showing the locks that lead to the deadlock).
Then in another window, run
Begin Transaction
Update Foo Set OtherData = 2 Where OtherKey = 'C5'
This will get a U lock on the index row in the FooIdx index, then try to get an X lock on the row in the clustered index. But that row is already exclusively locked, so this second window will wait holding a U lock on FooIdx row and is waiting for
an X lock on the clustered index row.
Now go back to the first window and run
Update Foo Set OtherData = 3 Where OtherKey = 'C5'
This will once again try to get the U lock on the FooIdx row, but it is blocked by the U lock the second window holds. Of course the second window is blocked by the X lock on the clustered index row and you have a deadlock.
All that said, I certainly do not routinely code my updates with UPDLOCK. I try to design databases and write code so that deadlocks will be rare without holding excessive locks. The more locks you hold and the longer you hold them, the more
blocking you will get and the slower your system will run. So I write code that if a deadlock exception occurs, it is properly handled. Then if too many deadlocks occur, that is the time to go back to the code to see what changes are needed to
decrease the number of deadlocks (one way to do that may be to get locks earlier and/or hold them longer.
But I wouldn't worry much about this form of deadlock. It is, in my experience, vary rare. I don't recall ever seeing it in a production environment.

For update in select statement

i have a table which store data in a clob. sometimes user forget to add and extra carriage return after last line. so i am doing the following to modify the clob
SELECT file_content INTO lv_lob FROM files WHERE id = p__id FOR UPDATE;
dbms_lob.writeappend(lv_lob,2,C_NEW_LINE);
C_NEW_LINE CONSTANT VARCHAR2(2) := Chr(13)||Chr(10);
'for update' should only lock that specific row since id is a pk key in the table.
i have two front end screen where people upload file. a unique id is generated for each file and the data with id inserted in the table. user can upload file from the two different screen at same time.
the problem is that i am getting a 'resource busy and acquire with NOWAIT specified' error. i don't know why if every file i upload belongs to different row.
anybody knows why i would get this error and how can i solve it?

How are you generating the unique ID? Are you using a sequence? Or are you using something that forces serialization?
Where in the program flow are you adding the extra carriage return?
Is it this SELECT statement that is throwing the error? Or is it being thrown somewhere else?

Update From Select statement

I'm very new to Oracle so please bear with me.
I need to Update a table ( T1) with dates selected from another table (T2). However, because of the size of the tables (the second one has upwards of 3,000,000 rows) I have to do it incrementally, say 10k rows at a time. However, there's no field in T1 that I can use as a flag to say the row's been updated. But I do have an ascending numeric field that I can do a Max() function on. My thought was to capture the max numeric function in local variable and use it in a where clause so I only get the rows I need to update. Pseudo-ish code follows:
DECLARE
mDoc NUMBER
maxNum NUMBER
BEGIN
mDoc = 0;
SELECT MAX(doc_id_n) INTO maxNum FROM T2;
WHILE NOT mDoc > maxNum
LOOP
SELECT MAX(doc_id_n) INTO mDoc FROM T2
WHERE doc_id_n > mDoc AND rownum < 10001;
UPDATE T1 SET scan_d =
(select to_date(t.ddate,'MM/DD/YYYY') as ndate
from T2 t, T1 i
where i.stor_rep_id = 'HRPAYROLL1' and
t.doc_id_n = i.doc_id_n and rownum < 10001
AND NOT t.doc_id_n > mDoc
ORDER BY t.doc_id_n)
END LOOP;
END;

You say:
<However, there's no field in T1 that I can use as a flag to say the row's been updated.
That's fine, you needn't nor might you want to do this incrementally. Instead, what basis or values in table(T1) are you using to determine which rows are updated? For example, you might want to use a particular field as your 'filter' between the two tables. Still it's not fun :)
UPDATE T1 SET date_column = (SELECT inserted_date FROM T2 WHERE customer = 'ABC')
WHERE customer = 'ABC';
UPDATE T1 SET date_column = (SELECT inserted_date FROM T2 WHERE customer = 'XYZ')
WHERE customer = 'XYZ';
Hope this helps.

Please send me select statement for the below query.....

FOR i IN 1..9 LOOP
IF shift(i) IS NULL THEN
FOR y IN i+1..9 LOOP
IF shift(y) IS NOT NULL THEN
shift(i) := shift(y);
shift(y) := NULL;
EXIT;
END IF;
END LOOP;
END IF;
END LOOP;
please how to write select query to replace loops in above code

CREATE or REPLACE function MyFun(
code_1 IN VARCHAR2,
code_2 IN VARCHAR2,
code_3 IN VARCHAR2
)RETURN INTEGER IS
out_param INTEGER:=0;
TYPE t_cos IS TABLE OF VARCHAR2(30) INDEX BY BINARY_INTEGER;
shift t_cos;
i NUMBER;
y NUMBER;
BEGIN
shift(1) := TRIM(code_1);
shift(2) := TRIM(code_2);
shift(3) := TRIM(code_3);
FOR i IN 1..3 LOOP
IF shift(i) IS NULL THEN
FOR y IN i+1..3 LOOP
IF shift(y) IS NOT NULL THEN
shift(i) := shift(y);
shift(y) := NULL;
EXIT;
END IF;
END LOOP;
END IF;
END LOOP;
For i IN 1..3 Loop
IF substr(shift(i),1,1) = 'E' THEN
out_param := shift(i);
EXIT;
ELSE
out_param := NULL;
END IF;
END LOOP;
out_param := 1;
RETURN (out_param);
END;
For Ex we have 100 recors this loops i.e For loops executes more than 100 times we need to avoid this thing and replace for loop's and write select stmt on this.

Combine two select statements in one SQL statements

I have the following two queries that I need to combine into one query, where it updates a single row at the same time.
SELECT count(*) FROM database.USAGE WHERE SERVICE_TYPE = 'C' AND ACCOUNT = "4837"
SELECT sum(minutes) FROM database.USAGE WHERE SERVICE_TYPE = 'DA' AND ACCOUNT = "4837"
I want to insert the values of each select statement into two columns of the same row, as well as insert the account number from the select statement.
After the query has been executed, the database row will look like this:
ACCOUNT COUNT SUM
4837 354 1039202
I am looking for suggestions on how to:
- either combine the two into one query
- simply update each column with the value from each query by updating the row with the account value
I am a SQL newbie - so I appreciate any assistance.
Thanks,
Tony

Hi, Tony,
When you're talking about changing the data in tables, "INSERT" means to add a new row, and you'll cause a lot of confusion if you use it to mean something else. So don't say
"I want to insert the values of each select statement into two columns..."; use some other word, like:
"I want to put the values of each select statement into two columns ..."
If you happened to know that those two numbers were 354 and 1039202, you might say:
UPDATE table_x
SET     a_count = 354
,       a_sum = 1039202
WHERE   account = 4837;But you don't know the numbers; you want to have the query figure out what they are.
In most places where you can use a literal (like 354 or 1039202), you can also use a scalar sub-query, a SELECT statement, enclosed in parentheses, that produces one column and (at most) one row.
In your case, you can say:
UPDATE table_x
SET     a_count = (SELECT count(*) FROM database.USAGE WHERE SERVICE_TYPE = 'C' AND ACCOUNT = 4837)
,       a_sum = (SELECT sum(minutes) FROM database.USAGE WHERE SERVICE_TYPE = 'DA' AND ACCOUNT = 4837
WHERE   account = 4837;or, to make it more readable:
UPDATE table_x
SET     a_count =
( SELECT count (*)
FROM database.USAGE
WHERE SERVICE_TYPE = 'C'
AND ACCOUNT = 4837
,       a_sum =
( SELECT sum (minutes)
FROM database.USAGE
WHERE SERVICE_TYPE = 'DA'
AND ACCOUNT = 4837
WHERE   account = 4837;By the way, why are you using double-quotes around 4837? If it's a string, enclose it in single quotes. If it's a number (which I'm assuming in my code), don't enclose it in anything.
WARNING: scalar sub-queries are somewhat like duct tape: they're extremely useful in certain places, and those places account for about 1% of their use. The other 99% of the time, there's a better way to do things, though the better way may require more expertise.

DOCUMENTING SELECT STATEMENT

Hi All,
I been working with databases (ORACLE, MSSQLSERVER, SQLANYWARE) for last couple of years. SELECT statement comes into picture very frequently.
But yet I am unable to find any template, tool or hint to document the SELECT statement, so that other developers can understand its flow and relationships among source files. Every time a source given to developer (other than who actually write it) with SELECT statement, it takes long time to understand.
Any hint/help would be highly appreciated.
Regards.

For 90-some percent of the SQL statements you're likely to come across, this would seem to be an issue of developer training rather than of documentation. If your developers are accostomed to thinking in terms of set-based processing rather than procedural-based programming, the structure of a SQL statement ought to be rather self-explanatory. If there are a lot of DECODE statements or the SQL statement is doing something unusual, putting an explanatory comment nearby might be helpful.
Of course, this assumes that the developers are reasonably familiar with the data model of the underlying tables. If not, make sure they have the necessary ERD(s) and other documentation.

Combine select and update into single statement,without bind-variable

I have a problem, that I think is not possible to solve the way I want to, but I just wanted to check before leaving the idea...
I am looking for a way to combine the select and the update statement into one single statement. This is what I wan't to achive: select some data, and update the data selected before returning them.
On this site http://www.psoug.org/reference/update.html I see that the following are possible:
var bnd1 NUMBER
var bnd2 VARCHAR2(30)
var bnd3 NUMBER
UPDATE employees
SET job_id ='SA_MAN', salary = salary + 1000,
department_id = 140
WHERE last_name = 'Jones'
RETURNING salary*0.25, last_name, department_id
INTO :bnd1, :bnd2, :bnd3;
I need to have this as a single statement, and cannot use bind-variables. So I was hoping that something like this could be possible:
UPDATE customer c
SET c.HAS_CREDIT ='1'
WHERE c.HAS_CREDIT = '0'
RETURNING c.CUSTOMER_NO, c.FIRSTNAME, c.LASTNAME
where c.HAS_CREDIT = '1'
But this doesn't compile, complaining of missing into (ORA-00925: missing INTO keyword). And even though I would like this to be possible because this would solve my current problem, I think it would be very confusing. For instance; would the where clause of the returning part be operating after the update or before?
Any comments or suggestions on how to get it work in a single statement, or should I just leave this path straight away?

Hi,
RETURNING only works with bind variables, see
http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14261/returninginto_clause.htm#sthref3006
The real problem is that the form of RETURNING clause with bind variables is only valid for single row update or insert statements.
To update (or insert) multiple rows and return the data, you will need to use
RETURNING BULK COLLECT INTO clause. See
http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14261/tuning.htm#sthref2236

Database hints in select statement

Hi all,
i need to apply the databaser hints for my select statement where i am using for all entries clause .But the issue is that i am getting the dump when i am tring with the same .
If i use the hint without all entries clause ,it runs fine.
The query where i need to apply the hint is :

Hi,
Complex database statements or large numbers of secondary indexes that can be very
similar make it difficult for the database optimizer and the R/3 database interface to process
most efficiently. In some database systems, you can expressly influence decisions made by
database optimizer by what are known as hints.
Ex- %_HINTS ORACLE '&SUBSTITUTE VALUES&'.

updated records: 1274There are about 20 or so other procedure in the import script. I don't want to rewrite them.
Does anyone know why the UPDATE/SELECT is failing? I checked Metalink and could not find anything about this problem.

This is now an Oracle bug, #9182070 on Metalink.
TDE (transparent data encryption) does not work when an update/select statement references a remote database.

Update with a select statement

hi experts,
I need some help again.. :)
I have an insert query here with a select statement.. Juz wondering how to do it in update?
insert into newsmail_recipient
        (IP_RECIPIENTID,NF_LISTID,NF_STATUSID,D_CREATED,D_MODIFIED,C_NAME,C_EMAIL,USER_ID,NEWSMAIL_ID)
        select newsmail_recipientid_seq.nextval
          , liste
          , 1
          , sysdate
          , sysdate
          , null
          , null
          , ru.nf_userid
          , null
        from roleuser ru, unit u, userinfo ui
        where u.ip_unitid = ru.nf_unitid
        and u.ip_unitid = unit_id
        and ui.ip_userid = ru.nf_userid
        and ui.nf_statusid = 1
        and n_internal = 0
        and ui.ip_userid not in (select user_id
                                   from newsmail_recipient
                                  where user_id = ui.ip_userid
                                    and nf_listid = liste
                                    and nf_statusid = 1);let me know your thoughts.

MERGE can UPDATE existing rows, and INSERT new rows at the same time. In a MERGE statement, you give a table or a sub-query in the USING clause, and define how rows from that result set match rows in your destination table. If rows match, then you can UPDATE the matching row with values from the sub-query.
Very often, MERGE is easier to use, and perhaps more efficient, than UPDATE just for changing existing rows. That is, while MERGE can do both INSERT and UPDATE, it doesn't have to . You can tell MERGE just to do one or the other if you wish.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Since you're asking about a DML statement, such as UPDATE, the sample data will be the contents of the table(s) before the DML, and the results will be state of the changed table(s) when everything is finished.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

Update Statement using SELECT statement

The following select query return 1 record to me
[code]
select deptno , dname, empno , max_date, max(v_num)
from (select d.deptno , d.dname , e.empno ,max (ver_date) over(partition by d.id ,d.no) max_date ,v_num
            from emp e ,dept d
          where e.deptno=d.deptno and e.dname = d.dname and e.empno=1 and d.deptno =3 )
group by deptno , dname, empno , max_date
[/code]
Now I need to update the above value to the emp table itself
In emp table for the empno=1 I need to update the columns mx_Date and v_num columns with the above last 2 columns in the select statement (max_date, max(v_num) )
How can I write the update statement for this.
Thank You

Something like this
merge into emp e1
using (
          select deptno
               , dname
               , empno
               , max_date
               , max(v_num) v_num
            from (
                   select d.deptno
                        , d.dname
                        , e.empno
                        , max (ver_date) over(partition by d.id , d.no) max_date
                        , v_num
                     from emp e
                        , dept d
                    where e.deptno = d.deptno
                      and e.dname = d.dname
                      and e.empno = 1
                      and d.deptno = 3
           group
              by deptno
               , dname
               , empno
               , max_date
      ) e2
   on (
        e1.empno = e2.empno
when matched then
    update set e1.mx_date = e2.max_date,
               e1.v_num   = e2.v_num

Hint in Update or Select Statement in an inline query ??
