Hi,
1) RESULT_PACKAGE internal table contains any duplicate records or not bassed on the where condotion like below
2) Remove the into CORRESPONDING FIELDS OF table instead of that into table use.
refer the below code is
RESULT_PACKAGE1[] = RESULT_PACKAGE[].
sort RESULT_PACKAGE1 by /BIC/ZREB_SDAT AGREEMENT /BIC/ZLITEM1.
delete adjustant duplicate form RESULT_PACKAGE1 comparing /BIC/ZREB_SDAT AGREEMENT /BIC/ZLITEM1.
SELECT /BIC/ZSETLRUN AGREEMENT /BIC/ZREB_SDAT /BIC/ZLITEM1
from /BIC/PZREB_SDAT
into table i_tab
FOR ALL ENTRIES IN RESULT_PACKAGE1
where
/bic/ZREB_SDAT = RESULT_PACKAGE1-/BIC/ZREB_SDAT
AND
AGREEMENT = RESULT_PACKAGE1-AGREEMENT
AND /BIC/ZLITEM1 = RESULT_PACKAGE1-/BIC/ZLITEM1.
and one more thing your getting 10 million records so use package size in you select query.
Refer the following link also For All Entry for 1 Million Records

I need to know the proper syntax for my SELECT query, please.

Hello All,
Quick one for you:
Let's say that I have several columns in a table with names such as subject_1, subject_2, subject_3, etc. The table's name is subject_names.
The number in each of the three column name examples is also a value passed along a query string, the user can select choices, 1, 2 or 3. That query string's variable is $qs.
So, what I want is a SELECT query that uses the query string value as follows (KEEP IN MIND, I know this is not the proper syntax):
"SELECT subject_[$qs]
FROM subject_names";
I have tried all sorts of cominations of quotes (single and double), dots, brackets, braces and parenthesis. I just want to know how to include such a variable within this code.
Any and all help is sincerely appreciated!
Cheers,
wordman

Well, I did give you the syntax though.
$query = 'SELECT ' . $qs . ' FROM tbl_name';
I put spaces between the periods this time to make it more clear.
If you put the actual word 'subject' in there and just want your form to name it's options as the numbers available you could do this:
$query = 'SELECT subject_' . $qs . ' FROM tbl_name';
In PHP you can use either single or double quotes around your query string, I always just use single quotes. I see a lot of other use double quotes.
Double quotes would look like:
$query = "SELECT subject_' . $qs . ' FROM tbl_name";
Or when using double quotes you can actually just place the variable right in the string without having to concatenate multiple strings like above.
Since you mentioned that you are good with passing variables I probably don't have to mention that you need to set the value attribute of your option tags (if you are using a select) to the value you want them to pass.
Ex:
<select name="choices">
     <option value="1">1</option>
     <option value="2">2</option>
     <option value="3">3</option>
</select>
If you have that part all figured out then you can use the syntax above for your query string.
Good luck.

How can replace IF condition for a Select query in my reports?

IF s_bukrs-LOW = '4312' OR s_bukrs-LOW = '4313' OR s_bukrs-LOW = '4349' .
ELSEIF s_bukrs-LOW = '4310' OR s_bukrs-LOW = '4311' OR s_bukrs-LOW = '4587'.
ENDIF.
What if I want to use select query in place of IF condition, in my report for a Z -table in which I have made entries of ZZUSEREXIT-my progam name ,VAR1-4310,VAR2-4311,VAR3-4312,VAR4-4313,VAR5-4349,VAR6-4587?

HI
U can do this by two ways-
(1) Using Two SELECT statementsie. one for IF statements and second for ELSEIF statements.
Like--
SELECT < field name>,
WHERE s_bukrs-LOW = '4312' OR s_bukrs-LOW = '4313' OR s_bukrs-LOW = '4349'
SELECT < field name>,
WHERE s_bukrs-LOW = '4310' OR s_bukrs-LOW = '4311' OR s_bukrs-LOW = '4587'.
(2) U can do this in using IF with select statements.
This will help u

"System Resource Exceeded" for simple select query in Access 2013

Using Access 2013 32-bit on a Windows Server 2008 R2 Enterprise. This computer has
8 GB of RAM.
I am getting:
"System Resource Exceeded" errors in two different databases
for simple queries like:
SELECT FROM .... GROUP BY ...
UPDATE... SET ... WHERE ...
I compacted the databases several times, no result. One database size is approx 1 GB, the other one is approx. 600 MB.
I didn't have any problems in Office 2010
so I had to revert to this version.
Please advise.

Hi Greg. I too am running Access on an RDP server. Checking Task Manager, I can see many copies of MSACCESS running in the process list, from all users on the server. We typically have 40-60 users on that server. I am only changing the Processor Affinity
for MY copy, and only when I run into this problem. Restarting Access daily, I always get back to multi-processor mode soon thereafter.
As this problem only seems to happen on very large Access table updates, and as there are only three of us performing those kind of updates, we have good control on who might want to change the affinity setting to solve this problem. However, I
understand that in other environments this might not be a good solution. In my case, we have 16 processors on the server, so I always take #1, my co-worker here in the US always takes #2, etc. This works for us, and I am only describing it here in case it
works for someone else.
The big question in my mind is what multi-threading methods are employed by Microsoft for Access that would cause this problem for very large datasets. Processing time for an update query on, say, 2 million records is massively improved by going down
to 1 processor. The problem is easily reproduced, and so far I have not seen it in Excel even when working with very large worksheets. Also have not seen it in MS SQL. It is just happening in Access.

Need help for SQL SELECT query to fetch XML records from Oracle tables having CLOB field

Hello,
I have a scenario wherein i need to fetch records from several oracle tables having CLOB fields(which is holding XML) and then merge them logically to form a hierarchy XML. All these tables are related with PK-FK relationship. This XML hierarchy is having 'OP' as top-most root node and ‘DE’ as it’s bottom-most node with One-To-Many relationship. Hence, Each OP can have multiple GM, Each GM can have multiple DM and so on.
Table structures are mentioned below:
OP:
Name                             Null                    Type
OP_NBR                    NOT NULL      NUMBER(4)    (Primary Key)
OP_DESC                                        VARCHAR2(50)

Appreciate your help in this regard!

Hi,
A few questions :
How's your first query supposed to give you an XML output like you show ?
Is there something you're not telling us?
What's the content of, for example, <OP_PAYLOD_XML1> ?
I don't think it's a good idea to embed the node level in the tag name, it would make much sense to expose that as an attribute.
What's the db version BTW?

How to reduce logical count and scan count for a select query

hi,
I have two tables one is master and other is history. i need to combine this two tables into one temporary table.
I am using the below query to create temp table.
Select * into temporders
from
(select * from orders
union
select * from ordershistory) b
where updateon= (select max(updateon)from (select updateon,name,units,subunits from orders
union
select updateon,name,units,subunits from ordershistory) a
where updateon <='11/08/2008 11:18 AM' and a.name=b.name and a.units=b.units and a.subunits=b.subunits group by name,units,subunits)
order by report,subunitsorder
the statistics for this query:
SQL Server parse and compile time:
CPU time = 47 ms, elapsed time = 62 ms.
Table 'Worktable'. Scan count 556, logical reads 1569, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'ORDERSHISTORY'. Scan count 116, logical reads 339, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'ORDERS'. Scan count 116, logical reads 285, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
SQL Server Execution Times:
CPU time = 32 ms, elapsed time = 63 ms.
(115 row(s) affected)
you see logical reads and scan count for worktable(temporary) is quite high.
So anyone can give a solution for reduce the scan count and logical reads.
NOTE: name,units, subunits,updateon columns have primarykey

Dynamic fetch for dynamic sql query

Hi All,
I want to dynamically create a query and fetch it into a dynamic cursor record...The structure of the record should be the same as that of the query...
Can you suggest any method to do that.
eg
OPEN <dynamic cur> FOR <dynamic stmt>;
LOOP
FETCH <dynamic cur> INTO <dynamic rec>;
END LOOP;
CLOSE <dynamic cur>;
How do I declare the dynamic rec here?I would not know the columns in the query beforehand either.
Thanks,

Hi All,
I want to dynamically create a query and fetch it into a dynamic cursor record...The structure of the record should be the same as that of the query...
Can you suggest any method to do that.And how are you expecting to write an application around a dynamic query and dynamic structure that you don't know?
Saying that, as others have said, there is the DBMS_SQL package which can be used for certain valid reasons such as the following example....

CREATE OR REPLACE DIRECTORY TEST_DIR AS '\tmp\myfiles'
GRANT READ, WRITE ON DIRECTORY TEST_DIR TO myuser

Data fetching problem in select query

HI Expert,
               Pls check the below code as data is not fetching due to BGMKOBJ-OBJNR(22) not equal to EQKT-EQUNR(18).
select EQUNR
        EQKTX
       from EQKT into corresponding fields of table IT_EQKT
       from EQKT into table IT_EQKT
         into table IT_EQKT
         from EQKT
       for all entries in IT_BGMKOBJ
       for all entries in IT_ITOB
         where EQUNR = IT_ITOB-OBJNR
        and spras eq 'EN'.
Pls help me with code.
Thanks & Regards,
Singha

Create a new internal table with the field EQUNR with BGMKOBJ-OBJNR values and do for all entries on this table.There is no alternative on this.
e.g,
types: begin of t_equnr,
equnr type EQKT-EQUNR,
end of t_equnr.
data : it_equnr type table of t_equnr,
         wa_equnr type t_equnr.
loop at IT_BGMKOBJ into wa_BGMKOBJ .
wa_equnr-equnr = wa_BGMKOBJ-OBJNR.
append wa_equnr to it_equnr.
endloop.
select EQUNR
EQKTX
from EQKT into corresponding fields of table IT_EQKT
from EQKT into table IT_EQKT
into table IT_EQKT
from EQKT
for all entries in IT_BGMKOBJ
for all entries in it_equnr
where EQUNR = it_equnr-EQUNR

Concurrent access issue with JPA for a Select query?

I'm not sure what a Broker is in OpenJPA so you may want to post in an OpenJPA forum. I would suspect though that a broker is underneath the EntityManager, and it might suggest that this EntityManager instance is being shared among threads. Verify that the EntityManager returned is not being used in multiple threads; if it is used in multiple threads concurrently, this needs to be changed to obtian a new one and release it when done as they are not thread safe. You might also try using EclipseLink as the JPA provider to see if you get a different error message that might point out the problem.

Displaying different no. of records for a select Query for the same dbuser

Hi,
While querying from my machine after connecting to custom schema it is displaying 3000 rows.
When the same query was executed from different machine it is displaying just 31 records.
1. Connect as xxyy user and executed the below command
select count(*) from xxyy. XXYY_APAR_SUPP_CUST_MAST_V.
output is showing some 3000 records
2. Connect as xxto user and executed the below commands for a specific user and specific machine
select count(*) from xxyy. XXYY_APAR_SUPP_CUST_MAST_V.
output is showing just 31 records
Please help...!!

Hi,
I hope you would have resolved the problem, if not, next step could be to check the TNS on both machines because now i suspect that your TNS on other machine points to some idfferent database.
What do you mean by following
2. Connect as xxto user and executed the below commands for a specific user and specific machineSo you connect with different users? If yes, then from both machines, if you connect with the same user, is result same?
When the same query was executed from different machine it is displaying just 31 records.Please paste the TNs entry for the database from both of your client machines from where you run the query.

Fetching values using select query

Hi i want to get the details of belnr and bukrs using the where codn fields bukrs,anlkl,brdatu,ktansw,budat,WBS element.
1)The value of bukrs is entered in the selection screen
2)the value of asset class is optional and present in the anka
3)brdatu is already fetched and placed in a table.field brdatu is present in table j_ittaxdep
4)ktansw is entered in the selection screen and present in table j_ittaxdep
5)budat is fetched and placed in a table.
6)wbs element already fetched and is present in prps table.
Can anyone please tell how to code.actually the values of bukrs,anlkl ktansw, are present in structure anlav,brdatu is present in structure rbada and budat is present in structure anek.By using this structure is there way to get the belnr and bukrs value.

Hi,
Hema,
things are not so flate as you are thinking.
first u understand for which application u are using these Queries.Ask ur functional guy to confirm the usage tables.Then use thsee tables to get the data into u r internal tables and for these internal tables value u have to fetch belnr bukrs fronm bseg or FI table .

Simple SELECT query to generate INSERT for a table

Hi,
I am looking for a SELECT query which generates INSERT statements for a table.Please guide.
Thanks
PG.

Like this?
SQL> SELECT * from kons;
     COL1      COL2
        1         1
        2         2
SQL> SELECT 'INSERT INTO kons VALUES('||col1||','||col2||');' statement FROM kons;
STATEMENT
INSERT INTO kons VALUES(1,1);
INSERT INTO kons VALUES(2,2);
SQL> If you have character and / or date columns you will have to change my example,
but you might get the idea from it.
You can spool the result to a file.
Regards,
Guido
Edit: ';' added to end of statement...
