Performance problem(ANEA/ANEP table) in Select statement

Hi
I am using below select statement to fetch data.
Does the below where statement have performance issue?
can you Pls suggest.
1)In select of ANEP table, i am not using all the Key field in where condition. will it have performance problem?
2)does the order of where condition should be same as in table, if any one field order change also will have effect performance

1. Yes. If you have only a few primary keys in youe WHERE condition that does affect the performance. But some times requirement itself may be in that way. We may not be knowing all the primary keys to given them in WHER conditon. If you know the values, then provide them without fail.
2. Yes. It's better to always follow the sequence in WHERE condition and even in the fields being fetched.
One important point is, whenever you use FOR ALL ENTRIES IN, please make sure that the itab IS NOT INITIAL i.e. the itab must have been filled in. So, place the same conditin before both the SELECT queries like:
IF i_anla[] IS NOT INITIAL.
SELECT bukrs
         anln1
         anln2
         afabe
         gjahr

     AND afabe IN s_afabe

Using plsql tables in select statement of report query

Hi
Anyone have experience to use plsql table to select statement to create a report. In otherwords, How to run report using flat file (xx.txt) information like 10 records in flat files and use this 10 records to the report and run pdf files.
thanks in advance
suresh

hi,
u can use the utl_file package to do that using a ref cursor query in the data model and u can have this code to read data from a flat file
declare
ur_file utl_file.file_type;
my_result varchar2(250);
begin
ur_file := UTL_FILE.FOPEN ('&directory', '&filename', 'r') ;
utl_file.get_line(ur_file, my_result);
dbms_output.put_line(my_result);
utl_file.fclose(ur_file);
end;
make sure u have an entry in ur init.ora saying that your
utl_file_dir = '\your directory where ur files reside'
cheers!

FETCHING VALUES IN MULTI RECORD BLOCK FROM ANOTHER TABLE USING SELECT STATEMENT.

Hi,
I have one multi record block in which i want to fetch values
(more then one record) from another table using select statement
IN KEY NEXT ITEM.I am getting following error.
ORA-01422: exact fetch returns more than requested number of rows
Thanks in advance.

In your case I see no reason to use non-database block and to try to populate it from a trigger with a query, instead of using the default forms functionality where you can associate the block and the fields with table, create where clause using bind variables and simply use execute_query() build-in to populate the block. The power of the forms is to use their build-in functionality to interact with the database.
Also, you can base your block on a query, not on a table and you dynamically change this query using set_block_property() build-in. You can use any dynamic queries (based on different data sources) and you simply need to control the column's data type, the number of the columns and their aliases. Something like creating inline views as a block data source.
However, you can replace the explicit cursor with implicit one like
go_block('non_db_block_name');
first_record();
FOR v_tab IN (SELECT *
FROM tab
WHERE col_name = :variable)
LOOP
:non_db_block_name.field1 := v_tab.col1;
:non_db_block_name.field2 := v_tab.col2;
next_record();
END LOOP;

Problem in creaing the logical tables by SELECT statement

Hi,
I have created logical tables in the physical layer of the OBIEE tool by "select statement". Connection Pool is set up properly for the repository. Rows of the tables are updating properly by clicking to the "Update Row Count" but when I am clicking to the "View Data" it shows the following error
[nQSError:17001] Oracle Error code:936, message: ORA-00936:missing expression at OCI call OCIStmtExecute.
[nQSError:17010]SQL statement preparation failed.
Also for some tables data is coming properly by clicking to the "View Data" .
I'm stack in this point and cannot move forward. Please, help me guys.
Thanks
Sandeep

Hi
I also face same type of error. Just do one thing Change the call interface OCI 10g to ODBC 3.5 and on Feature tab click revert to default.
I think that will work properly.
Best of Luck

"Check Statistics" in the Performance tab. How to see SELECT statement?

Hi,
In a previous mail on SDN, it was explained (see below) that the "Check Statistics" in the Performance tab, under Manage in the context of a cube, executes the SELECT stament below.
Would you happen to know how to see the SELECT statements that the "Check Statistics" command executes as mentioned in the posting below?
Thanks
====================================
When you hit the Check Statistics tab, it isn't just the fact tables that are checked, but also all master data tables for all the InfoObjects (characteristics) that are in the cubes dimensions.
Checking nbr of rows inserted, last analyzed dates, etc.
SELECT
T.TABLE_NAME, M.PARTITION_NAME, TO_CHAR (T.LAST_ANALYZED, 'YYYYMMDDHH24MISS'), T.NUM_ROWS,
M.INSERTS, M.UPDATES, M.DELETES, M.TRUNCATED
FROM
USER_TABLES T LEFT OUTER JOIN USER_TAB_MODIFICATIONS M ON T.TABLE_NAME = M.TABLE_NAME
WHERE
T.TABLE_NAME = '/BI0/PWBS_ELEMT' AND M.PARTITION_NAME IS NULL
When you Refresh the stats, all the tables that need stats refreshed, are refreshed again. SInce InfoCube queries access the various master data tables in quereis, it makes sense that SAP would check their status.
In looking at some of the results in 7.0, I'm not sure that the 30 day check is being doen as it was in 3.5. This is one area SAP retooled quite a bit.
Yellow only indicates that there could be a problem. You could have stale DB stats on a table, but if they don't cause the DB optimizer to choose a poor execution plan, then it has no impact.
Good DB stats are vital to query performance and old stats could be responsible for poor performance. I'm just syaing that the Statistics check yellow light status is not a definitive indicator.
If your DBA has BRCONNECT running daily, you really should not have to worry about stats collection on the BW side except in cases immediately after large loads /deletes, and the nightly BRCONNECT hasn't run.
BRCONNECT should produce a lof every time it runs showing you all the tables that it determeined should have stats refreshed. That might be worth a review. It should be running daily. If it is not being run, then you need to look at running stats collection from the BW side, either in Process Chains or via InfoCube automatisms.
Best bet is to use ST04 to get Explain Plans of a poor running InfoCube query and then it can be reviewed to see where the time is being spent and whether stats ate a culprit.

Hi,
Thanks, this is what I came up with:
st05,
check SQL Trace, Activate Trace
Now, in Rsa1
on Cube, Cube1,
Manage, Performance tab, Check Statistics
Again, back to st05
Deactivate Trace
then click on Displace Trace
Now, in the trace display, after scanning through the output,
how do I see the SELECT statements that the "Check Statistics" command executes
I will appreciate your help.

Create table as select statement.

Hello Oracle Gurus,
I am trying to create a table using select * from other table.
The procedure that I am following is this:-
I have a temp table whose signature is on commit delete rows.
I insert records in this table.
when I do select * from temp_table,perm_table I get some rows.
then I try to create a result_table using this
CREATE TABLE result_table
AS SELECT * FROM temp_table,perm_table;
I see the table in created but number of records in 0. Can anyone please explain where commit takes place while sequence in this query occurs.
Thanks
Edited by: user10696492 on Nov 10, 2009 8:47 AM

Create table statement is a ddl - so an implicit commit is performed before the create statement begins. The implicit commit will delete all the rows from the temp table. If it is feasible change the definition of the temp table to on commit preserve rows.

Picking the right values from tables - SQL (select statement)

Hi everyone,
I'm facing the litlle(?) problem in Oracle environment.
Let me explain:
I have two tables.
TABLE 1
Id1 | Val1 | Id2 | Val2
A | 44 | B | 36
B | 36 | A | 44
TABLE 2
Id | Name
A | New York
B | Seattle
I need to get from those tables, using SQL statement, result like this:
Id1 | Val1 | Name1 | Id2 | Val2 | Name2
A | 44 | New York | B | 36 | Seattle
NOTE !! Very important!! If in table 1 we have crossed the same values in fields IdX and ValX in two rows (like in example)- just one of them should be presented as a result.
I'm afraid it's a bit too complex. You, guys are my last hope.
Looking forward for any solutions.
Thanks in advance!

Create object type from multiple tables for select statement

Hi there,
I have 3 tables as given below and I wish to create an object type to group selected columns as 'attribute' from multiple tables.
I need to create 2 input parameters to pass in - 'attribute' and 'attribute value' in PL/SQL and these 2 parameters will be
passing in with 'column name' and 'column value'. e.g. 'configuration' - the column name, 'eval' - the column value.
Then, the PL/SQL will execute the select statement with the column and column value provided to output the record.
Pls advise and thank you.

Reason to do this as these fields are required to be grouped together as they are created in different tables. They are treated as 'attribute' (consists of many columns) of the part number. So, the PL/SQL is requested to design in a way able for user to pass in the column name and column value or part number, then the select statement should be able to query for the records. Another reason is a new column can be added easily without keep modifying those effected programs. Reuseable too.This basically equates to ... hard to code, hard to maintain, and poor performance.
Are you really sure you want to do this? This isn't going to be easy-street as you seem to think it is, but it's a one way street to a poorly performing system with security vulnerabilities (google SQL Injection).
I would highly recommend you reconsider your design decision here.

Performance problem while creating table at runtim

I have pl/sql block like
Begin
Exceute immediate 'drop table x '
Execute immediate 'create table x as select .... stament (complex select by joining 7-8 tables);
Execute immediate ('create index ind1 on table x'); -- i am not writing the full syntax
End;
The select statement used in create table is fetching 10 millions of rows (approx).
The above pl/sql block is taking 30-45 minutes.
Without going in depth of query used in select (as i have to explain the functionality otherwise),
Could any one please suggest to create a table in fatset way like nolooging or seperate tablespace with bigger block size or any change in any DB parameter etc.
The db server is having excelent hardware configuration 32GB ram , multi CPU (16 CPUs) , Huge hardisk.
Thanks

Performance problem when printing - table TSPEVJOB big size

Hi,
in a SAP ERP system there is performance problem when printing because table TSPEVJOB has many millions of entries.
This table has reached a considerable size (about 90 Gb); db size is 200 Gb.
Standard reports have been scheduled correctly and kernel of SAP ERP system is updated.
I've tried to scheduled report RSPO1041 (instead of RSPO0041) to reduce entries but it is not possible run it during normal operations because it locks the printing system.
Do you know why this table has increased ?
Are there any reports to clean this table or other methods ?
Thanks.
Maurizio Manera

Using Nested Table in Select Statement

Hi all ,
Can i use the PL/SQL nested table or Varray
in the select statement as a normal table joined with other database tables.
i.e.
I have a nested table NT_1 in PL/SQL proc
i have to use this NT_1 in the select statement as
select xxx from
tab_1,
tab_2,
NT_1
where
< some conditional joins >.
Please help me in this regard.

you can not use a varray as part of a SQL Statement in order to build joins.
Can you explain better what do you want to do ?

USING INDEXES DEFINED ON TABLES IN SELECT STATEMENTS

Hi there,
I would like to ask a simple question, how i can use indexes defined on certain columns on one of my database tables in a select clause:
table name: B2TECDOC
schema name: AWDBT1M4
indexes defined: AWDBT1M4.B2TECDOC_B2TECDOCKEY
index AWDBT1M4.B2TECDOC_B2TECDOCKEY is defined on columns:
documentname
documenttype
organizationid
organizationtype
revision
sequence
versionnumbercould you help me construct a select sql using this index?
another question is will using this index in my select clause increase the overall query performance?
thanks
rohan

A query like
SELECT *
FROM AWDBT1M4.B2TECDOC
WHERE documentname = <<some value>>
   AND documenttype = <<some value>
   AND organizationid = <<some value>>
   AND organizationtype = <<some value>>
   AND revision = <<some value>>
   AND sequence = <<some value>>
   AND versionnumber = <<some value>>should use the index.
An index is a more efficient way to access a relatively small fraction of the rows in the table. A table scan will be more efficient if you are trying to access a relatively large fraction of the rows in the table. Exactly what "small fraction" and "large fraction" means will depend on a variety of factors that the cost-based optimizer (CBO) attempts to evaluate in determing the query plan.

Dynamic table in select statement

Hi All,
I have a requirement where i have a select option in which the input is table name , i need to use this input in my select statement and fetch entries in the table where bname is eq to ' ' or uname eq ' '.
the challenge that i am facing is not all the tables have both the fields (uname and Bname).
Request your help on how to code the above requirements.
Thanks,
Bhanu.

Bhanu,
I don't know what exactly is your requirement but I don't see any reason why a business user enters a table name as input in the selection screen.
MANDT NAME                           TYPE NUMB SIGN OPTI   LOW    HIGH
223   ZPROGNAME                       P    0001     I        EQ    XXX      ZTABLENAME
You can maintain an entry like the above in TVARVC table and get the table name using a select query on TVARVC and then use the table as below
SELECT SINGLE * FROM (l_tabname)
           into g_wa_tab2
           WHERE quosrc   EQ g_wa_tab1-quosrc AND
                 quotyp   EQ g_wa_tab1-quotyp AND
                 quotno   EQ g_wa_tab1-quotno AND
                 quotdate EQ g_wa_tab1-quotdate.
Funda is using TAVRVC to maintain the table names and determine the table based on a condition and the using the table in the select query.
Thanks,
K.Kiran.
