How to avoid select query in loop
Hi All,
I have to select entries from table iclpay looping it_dfkkop and delete the entries in it_dfkkop_tmp which are not present in iclpay.
For this If use below code its working fine, but there is performance issue
CLEAR: it_iclpay[],it_iclpay.
LOOP AT it_dfkkop_tmp.
SELECT claim documentref paycat status FROM iclpay
APPENDING CORRESPONDING FIELDS OF TABLE it_iclpay
WHERE
active = c_active AND
claim = it_dfkkop_tmp-claim AND
documentref = it_dfkkop_tmp-opbel.
IF sy-subrc NE 0.
DELETE it_dfkkop_tmp.
ENDIF.
ENDLOOP.
If I write the code like below its not working
SELECT claim documentref paycat status FROM iclpay
INTO TABLE it_iclpay
FOR ALL ENTRIES IN it_dfkkop_tmp WHERE
active = c_active AND
claim = it_dfkkop_tmp-claim AND
documentref = it_dfkkop_tmp-opbel.
Can anyone help on this.
It did not dump but did not get final(required) output.
I got the solution now.
Thanks a lot for responding.
I have written the below code
SELECT claim
documentref
paycat
status
FROM
iclpay
APPENDING CORRESPONDING FIELDS OF TABLE it_iclpay
FOR ALL ENTRIES IN it_dfkkop_tmp WHERE
active = c_active AND
claim = it_dfkkop_tmp-claim AND
documentref = it_dfkkop_tmp-opbel.
SORT it_dfkkop_tmp BY claim opbel.
LOOP AT it_dfkkop_tmp.
READ TABLE it_iclpay INTO wa_iclpay WITH KEY
claim = it_dfkkop_tmp-claim
documentref = it_dfkkop_tmp-opbel.
IF sy-subrc NE 0.
DELETE it_dfkkop_tmp.
ENDIF.
ENDLOOP.

Please check the value of the variable sy-binpt, I believe the value of the variable sy-binpt will be set to 'X' if the program is called from a bath input, hope this helps. -
Urgent - I have written select query between loop and endloop, Ple help out
Can any one help out me on this select query. I have written select query between loop and endloop. When I execute the program it will take too much time in this query. Please help me out. Its very urgent.

Thanks in advance.Here is a way to solve this problem.
Choose somewhere before this loop processing to use that select. Therefore, you'll need use FOR ALL ENTRIES <that_loop_table> clause, and in the WHERE condition you need to specify that same fields.
This way, you will have an internal table with all data you'll need to check.
Then, inside your loop statement, use the READ TABLE command with the clause WITH KEY field = value, to read that record and use the value found.
Like this sample:
SELECT bukrs lifnr umsks umskz augdt augbl zuonr gjahr belnr buzei
waers xblnr blart gsber ebeln zfbdt zbd1t zlsch
INTO TABLE tg_bsak
FROM bsak
FOR ALL ENTRIES IN tl_bkpf_sel
WHERE bukrs EQ tl_bkpf_sel-bukrs AND
lifnr IN s_lifnr AND
augbl EQ tl_bkpf_sel-belnr.
LOOP AT tg_bseg INTO wa_bseg.
READ TABLE tg_bsak INTO wa_bsak WITH KEY bukrs = wa_bseg-bukrs
gjahr = wa_bseg-gjahr
belnr = wa_bseg-belnr
BINARY SEARCH.
if sy-subrc = 0.
* do something
endif.

How to avoid select with in a loop.
Hi friends,
can any tell how to avoid the select with in a loop for the following code, since it badly effecting my performance. if possible with code
SELECT matnr werks
FROM marc
INTO TABLE it_marc
FOR ALL ENTRIES IN it_ausp_1
WHERE matnr = it_ausp_1-objek AND
werks = p_werks
AND mmsta LE 60.
SORT it_marc BY matnr.
CLEAR wa_ausp_1.
CLEAR wa_tabix.
LOOP AT it_ausp_1 INTO wa_ausp_1.
wa_tabix = sy-tabix.
READ TABLE it_marc INTO wa_marc WITH
KEY matnr = wa_ausp_1-objek
BINARY SEARCH.
IF sy-subrc EQ 0.
ELSE.
DELETE it_ausp_1 INDEX wa_tabix.
ENDIF.
ENDLOOP. " LOOP AT it_ausp_1 INTO wa_ausp_1.
APPEND LINES OF it_ausp_1 TO it_tal.
IF it_tal[] IS NOT INITIAL.
LOOP AT t_plan_order INTO fs_plan_order.
SELECT r~rsnum
r~rspos
r~matnr
r~nomng
r~meins
r~plnum
r~bdter
r~ewahr
r~alprf

r~baugr
m~dispo
INTO TABLE t_resb

WHERE r~rsnum = fs_plan_order-rsnum
AND r~matnr = it_tal-objek
AND r~xloek = ' '
AND r~werks = p_werks.
APPEND LINES OF t_resb TO t_tacl.
ENDLOOP.SELECT r~rsnum r~rspos r~matnr r~nomng r~meins r~plnum r~bdter r~ewahr r~alprf r~posnr r~baugr m~dispo

FOR ALL ENTRIES IN it_tal
WHERE r~rsnum = fs_plan_order-rsnum
AND r~matnr = it_tal-objek
AND r~xloek = ' '
AND r~werks = p_werks.
The logic of this select is completely weird. Whcih order of the db-tables should be used, which indexes?
On RESB matnr, werks and xloek are in one index, but rsnum not.
Are the conditions in fs_plan_order and it_tal connected or independent?
It is probably much faster, to leave the fs_plan_order condition away and check it on the result.
SELECT r~rsnum r~rspos r~matnr r~nomng r~meins r~plnum r~bdter r~ewahr r~alprf r~posnr r~baugr m~dispo
INTO TABLE t_resb
FROM resb AS r
INNER JOIN marc AS m
ON m~matnr = r~baugr
AND m~werks = r~werks
FOR ALL ENTRIES IN it_tal
WHERE AND r~matnr = it_tal-objek
AND r~xloek = ' '
AND r~werks = p_werks.
sort fs_plan_order by rsnum.
loop at it_tal in wa.
read table fs_plan_order
with key rsnum = wa-rsnum
binary search.
if sy-subrc eq 0.
append ...
endif.
endloop.

How to avoid 'select for update'
Hi,
we are using the bc4j framework of jdev 3.2.3. We have a View which collects data from several tables in different database schemes, so we naturally have to use the 'union clause'. But if we try to make an update on a row (via 'setAttribute'), we got a DMLException ORA-02014 telling us that we should not use 'select for update' on views whith unions.
Since i cannot avoid using a union clause, is there a way to avoid the 'select for update' in the bc4j framework?
Please help, its urgent!
Thanx,
DietmarSELECT FOR UPDATE is used for our implementation or row-level locking.
If you are using pessimistic locking mode, this will occur the first time any attribute is modified.
If you are using optimistic locking mode, it will be deferred until post/commit time.
If you are using "none" locking mode, it will not happen in your application may hang indefinitely if another session has locked the row.
Are you asking how to avoid locking?
Do you mean to be updating this view with a union over multiple databases? -

How to write selection Query for the following requirment.
Hi All,
I am new to ABAP, I need a help ,
I need to select all plants(WERKS) from MARC at Plant/Material level,
then I need to take all sales organozation(VKORG) from T001w,
then I need the company code(BUKRS) from TVKO based on VKORG,
then I need the currency key(WAERS) from T001 based on BUKRS,
Can any one help me in writing selection Query for the same?
Thanks All,
Debrup.Hi,
Its easy for you if you learn SELECT with JOIN to complete your task. So SEARCH the forum with SELECT statement and you will get a lot of examples using which you can write your own.
If you struck up anywhere revert back.

You're in the wrong forum (this one is for issues with the SQL Developer tool). You were in the right one where you posted first, but don't reuse unrelated threads as you did.

Need help in logic change to avoid select statement inside loop .
Hello all ,
Please see the below code . Here i got the shipment number in internal table IT_VTTK . So For this shipment number i want to get the details from Vekp table in to internal table IT_VEKP . There is no need for me to use For all entries . I have passed the value of it_vekp into work area wa_vekp and getting the details in to IT_vekp using loop.
But since we should not use the select statement inside the loop , Can anybody please tell me how to achieve this functionality .
Instead of passing into work area wa_vttk if i directly use the internal table I'm getting the following error .
"IT_VTTK" is a table without a header line and therefore has no component called "TKNUM".
Hence i have used select statement inside a loop . Please tell me is there any other way to avoid this ?
types:begin of ty_likp,
vbeln type likp-vbeln,
end of ty_likp,
begin of ty_vttk,
tknum type vttk-tknum,
end of ty_vttk.
DATA: IT_VEKP TYPE STANDARD TABLE OF TY_VEKP,
WA_VEKP TYPE TY_VEKP.
data:it_likp type standard table of ty_likp,
wa_likp type ty_likp,
it_likp1 type standard table of ty_likp,
it_vttk type standard table of ty_vttk,
wa_vttk type ty_vttk.
data:w_tknum type vttk-tknum.
if not it_likp is initial .
select vbeln
from
vbfa
into table it_vttk
for all entries in it_likp where vbelv = it_likp-vbeln and vbtyp_n = '8'.
endif .
IF IT_VTTK[] IS NOT INiTIAL.
loop at it_vttk into wa_vttk.
SELECT venum
EXIDV
EXIDV2
BRGEW
NTGEW
GEWEI
TARAG
GEWEI
VHART
INHALT
FROM VEKP INTO TABLE IT_VEKP where VPOBJKEY = wa_vttk-tknum and vpobj = '4'.
endloop.
endif.Hello,
Why would you not like to use FOR ALL ENTRIES in the second select? Is it becasue of the length or type mismatch error between the fields VPOBJKEY and wa_vttk-tknum ?

How to write select query for all the user tables in database
Can any one tell me how to select the columns from all the user tables in a database
Here I had 3columns as input...
1.phone no
2.memberid
3.sub no.
I have to select call time,record,agn from all the tables in a database...all database tables have the same column names but some may have additional columns..
Eg: select call time, record,agn from ah_t_table where phone no= 6186759765,memberid=j34563298
Query has to execute not only for this table but for all user tables in the database..all tables will start with ah_t
I am trying for this query since 30days...
Help me please....any kind of help is appreciated.....Hi,
user13113704 wrote:

Starting in Oracle 10, you can also use Q-notation:
http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/sql_elements003.htm#i42617
...and also can you tell me how to execute the output of this script. What front end are you using? If it's SQL*Plus, then you can SPOOL the query to a file, and then execute that file, like this:
-- Suppress SQL*Plus features that interfere with raw output
SET FEEDBACK OFF
SET PAGESIZE 0
-- Run preliminary query to generate main query
SPOOL c:\my_sql_dir\all_ah_t.sql
SELECT 'select call time, record, agn from '
|| owner
|| '.'
|| table_name
|| ' where phone_no = ''6186759765'' and memberid = j34563298'
|| CASE
WHEN ROW_NUMBER () OVER ( ORDER BY owner DESC
, table_name DESC
) = 1
THEN ';'
ELSE ' UNION ALL'
END AS txt
FROM all_tables
WHERE SUBSTR (table_name, 1, 4) = 'AH_T'
ORDER BY owner
, table_name
SPOOL OFF
-- Restore SQL*Plus features that interfere with raw output (if desired)
SET FEEDBACK ON
SET PAGESIZE 50
-- Run main query:
@c:\my_sql_dir\all_ah_t.sql
so that i form a temporary view for this script as a table(or store the result in a temp table) and my problem will be solved..Sorry, I don't understand. What is a "temporary view"? -
How to write select query for this
Hi,
I had a html form and in the for i had drop down box and it needs to select multiple values from the drop down box. When i select multiple values then i have to write the SQL select statement query .
When i try to write the select statement and trying to run i am getting error.
select * from Table
where emo_no = '1,2,3'
this is how i write query please suggest me how to write query for selecting multiple values from the drop down box.
Thanksselect * from Table
where emo_no in ( 1,2,3)
for integer values
select * from Table
where emo_no in ('1','2','3')
for characters
If we talk about large scale applications that may have millions of records, I would suggest this.
declare @t table (v int)
insert into t (v) values (1)
insert into t (v) valves (2)
insert into t (v) values (3)
select *
from table
inner join @t t on table.emo_no = t.v
Using "in" for a where clause is not so bad for filtering on a few values, but if you are filtering a lot of rows and a lot of values (emo_no) the performance degrades quickly for some reasons beyond the scope of this.
This is just one solution, I'll through this out as well, instead of an in memory (@t) table, doing a disk based temp table (#t) and creating an index on the column "v".
create table #t (v int)
insert into #t (v) values (1)
insert into #t (v) valves (2)
insert into #t (v) values (3)
create index ix_t on #t (v)
select *
from table
inner join #t t on table.emo_no = t.v
drop table #t
Pardon any syntax errors and careful using a drop statement.
Sometimes in memory tables work better than disk temp tables, it takes some testing and trial and error depending on your datasets to determine the best solution.
Probably too much info ;-)

How to improve 'select query with subselects'?
Oracle Database 11g Release 11.1.0.7.0 - 64bit Production
PL/SQL Release 11.1.0.7.0Hi there,
I'm a C# developer so I really have troubles with understanding PL/SQL. I use a lot of subselects in my queries because I find it easy to understand, however, I need to learn to make use of the power of queries. I made this little library sample to illustrate the problem I have in a smaller scale. I have multiple subselects looking in the same table, running through the same amount of columns to obtain data. This is a waste of performance and resources.
Idea of the query:
Information about a book
- Location of this book
- Number of unique readers of this book
- Number of days it was rent
- Number of reservation of this book
Test data
with
book as (

)Normally my queries look like this
select b.id,

and rh.reservationdate < to_date('01-01-2013')
) as times_reserved
from book b
join location l
on b.locid = l.id I tried to improve it to this
select b.id,
b.reference,
b.title,
b.description,
b.author,
l.roomnumber,
nvl(t1.clients, 0) as different_readers,
nvl(t1.days, 0) as days_of_rent,

and bh.rentdate < to_date('01-01-2013')
group by bh.bookid
) t1
on t1.bookid = b.id I am told that I should try to move out the group by from the last left join or try to use partitioning.
Now this is a bit too much for my understanding. When I use partitioning
select distinct
b.id,
b.reference,
b.title,
b.description,
b.author,
l.roomnumber,
nvl(count(distinct bh.clientid) over (partition by bh.bookid), 0) as different_readers,

left join book_history bh
on b.id = bh.bookid
and bh.rentdate >= to_date('01-01-2012')
and bh.rentdate < to_date('01-01-2013')I suppressed same result rows by using distinct, however I am told to avoid using distinct as this slows down a lot.
Is there any other solution I can use to achieve the same?
I hope my question is clear enough to be answered! Thanks in advance for your time!

The index doesn't help for this query, so it's not used.
The main purpose of indexes is the help find a small number (like 1) of rows quickly. You're asking for all rows; getting each one through the index would be slower than just getting all of them directly.
Sometimes (but not here) the index can be used instead of the table, when the index contains all the data you need from the table. An index on cust_id doesn't tell you anything about any other column, such as cust_name. Since you asked to have all columns displayed, it has to fetch data from the table, not the index.
