Select Statement Query

Hi,
I need to perform the following selection:
a. Based on Position Number -> select associate Pernr from PA0001
b. based on this Pernr find value of STAT2 in PA0000.
Is there an efficient way of carrying out this selection other than using 2 Select Statements?
Note Pernr field is a primary key in both tables.

How about using join statement:
Since PERNR is a key field in both tables;
SELECT P0~STAT2
INTO TABLE <itab>
FROM PA0001 AS P1 INNER JOIN PA0000 AS P0
ON P1PERNR = P0PERNR
WHERE <position number condition>

Re: Select statement query

Hi Expert,
I have one report which display employee transfer details In that report i have added two new fields i.e Action type and Reason for Action.My requirement is in the selection screen i have given date.What ever date i have given in the selection screen it should fetch the data of employee transfer I have written the code but in the output the field which i have added
two fied i.e Action type and Reason for action data is not comming for this two fields.
Below is my code .
loop at p0000 where pernr = i_transfers-pernr and massn eq '02'.
    i_transfers-massg = p0000-massg.
    select single * from t530t into ls_t530t where massn eq '02' AND massg = i_transfers-massg AND sprsl = 'E'.

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!

Slow query results for simple select statement on Exadata

I have a table with 30+ million rows in it which I'm trying to develop a cube around. When the cube processes (sql analysis), it queries back 10k rows every 6 seconds or so. I ran the same query SQL Analysis runs to grab the data in toad and exported results, and the timing is the same, 10k every 6 seconds or so. r
I ran an execution plan it returns just this:
Plan

The Oracle version I'm using is 11.2.0.3.0 and the server is quite large as well (exadata platform). I'm curious because I've seen SQL Server return 100k rows ever 10 seconds before, I would assume an exadata system should return rows a lot quicker. How can I check where the bottle neck is?

I've notice the same querying speed using Toad (export to CSV)That's not really a good way to test performance. Doing that through Toad, you are getting the database to read the data from it's disks (you don't have a choice in that) shifting bulk amounts of data over your network (that could be a considerable bottleneck) and then letting Toad format the data into CSV format (process the data adding a little bottleneck) and then write the data to another hard disk (more disk I/O = more bottleneck).
I don't know exedata but I imagine it doesn't quite incorporate all those bottlenecks.
and during cube processing via SQL Analysis. How can I check to see if its my network speed thats effecting it?Speak to your technical/networking team, who should be able to trace network activity/packets and see what's happening in that respect.
Is that even possible as our system resides off site, so the traffic is going through multiple networks.Ouch... yes, that could certainly be responsible.
I don't think its the network though because when I run both at the same time, they both are still querying at about 10k rows every 6 seconds.I don't think your performance measuring is accurate. What happens if you actually do the cube in exedata rather than using Toad or SQL Analysis (which I assume is on your client machine?)

"select into" query statements using the DI API

I am trying to use the DI API (6.5) t create a temp table based on an existing table. For example, here is a query string....
select * into ORDR_TEMP from ORDR
Code...
oRecordSet := IRecordset(oCompany.GetBusinessObject(BoRecordset));
oRecordset.DoQuery(sSql);
Error I get...
1). [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot use SELECT INTO in browse mode. 2). [Microsoft][ODBC SQL Server Driver][SQL Server]Statement(s) could not be prepared
For any other regular select statements the previous code works. Does anyone know for sure if a "select into" statement is not possible using the DI API?

Hi Bill,
I´m not really sure if select into is avaiable. But here you´ve got a hint: You could use a user defined function to do it, and just call the function from your code.
SELECT dbo.MyFunction()
Having this function defined in your SQL Server:
CREATE function MyFunction ()
returns char(2)
AS
Begin
select * into ORDR_TEMP from ORDR
Return ('OK')
End
Hope this helps,

Need help with select statement or query

Not familiar with what to call it, but here is what i need...
To give our analyst a better idea of warranty on some of our
equipment, i
would like to add to the page a column that displays if the
device is still
under warranty
I currently capture the date the equipment was returned from
repair, so what
could i use within my select statement or query to display a
warranty
expiration date or display on the page...
example :
Returned from repair 10/20/2006 warranty expires on
11/20/2006
each equipment has different warranties, so i need a formula
or something to
say... device #1 has 60 day warranty ( so 10/20/2006 + 60days
=
12/19/2006 )
I would imagine this to be a query
Table 1 would contain the equipment type and warranty time
Table 2 would contain the current status of the equipment
Query would take the back from repair date + warranty =
expiration date

Simple. Join the two tables and create a derived column for
the expiration date. The exact syntax is dependant on your DBMS, so
check the manual for whichever you are using and look at the date
functions. There will be a function that will allow you to add a
number of date units (day, month, year, etc) to a date
field.

Query on Select Statement

Dear All,
        I have a small query on the Select Statement. If there are 2 identical rows and if i am retrieving them using the Select Statement, then will the select statement retrieves both the rows which are identical or only the first possible occurence? Pls help me out in this.
Thanks,
Sirisha.

Hi,
     That depends on the statement u use. If u use, 'SELECT' statment, u can retrieve all the records which are identical with one or few fields. For that, u need to put the output INTO A TABLE.
Ex. 1
data : int_ekko type table of ekko with header line,
         fs_ekko type ekko.
select * from ekko into table int_ekko where ebeln = '6361003191'.
Here, int_ekko is an internal table contains all records whose EBELN = 63610003191.
2) If u use 'SELECT SINGLE', then it will retrieve only the first record out of all the records who satisfy the condition EBELN = 6361003191.
Ex 2:
select single * from ekko into fs where ebeln = '63610003191'.
'fs' is not a table, just of type structure. so contains only one record.
Hope it help u..
Kindly reward points if hepful

Shanthi.

Query in SELECT statement!!!!

Hi all,
          I have a SELECT statement as follows:
SELECT aguid_hi bpartner_no
FROM crmd_link AS a
INNER JOIN crmd_partner AS b ON bguid EQ aguid_set
INTO TABLE p_partners
FOR ALL ENTRIES IN i_sub_contracts
WHERE a~guid_hi     EQ i_sub_contracts-guid
    AND a~objtype_hi EQ '05'
    AND b~partner_fct EQ p_partner_fct.
Please tell me if I can create a view for the above.
Once I create a view for the above will it really boost the performance.
Kindly reply immediately as this is bit urgent.
Regards,
Vijay

hi,
As said above view is nothing but an inner join between tables which you are already doing it in your program ... So i don't think there will be any improvement in the performance of the program ...

Query regarding Oracle SQL select statement

Hi,
How does Oracle ensures a consistent snapshot with the select statement
without locking the table. My question is summarized with an example below:
1. At time T1, Oracle select statement is fired and is fetching the result.
2. At time T2, some DML operation is performed on the same table on which
the select was executed and a commit was fired.
3. At time T3, The Oracle select statement (Step 1) completes.
My question is whether the records of transaction at time T2 will be visible at time T3 or not?
If "not", then does it mean that Oracle retrieves the rows from the time of last commit.
I would also like to know if for the above mechanism, Oracle would make use of the rollback segemt to access the rows at a particular instant of time.
TIA
Regards,
Raj

This is called Read Consistency in the oracle. Its all about SCN before starting the transaction.
Lets say
1. T1 executs SELECT statement on EMP table.
2. T2 made an update on the EMP and commited.
But, T1 only still sees only old image of the data not the new one. This is called read consistency.
You will be having two images in the buffer, one is consistent and changed image.
When the T1 give SELECT statement it notes the SCN of the transaction. Read oracle document about read consistency.

Querying many tables at once from a select statement for specific values

Hi all,
I'm very new to PL/SQL and have a daunting task ahead of me. I'm pretty sure our database normalization scheme is all out of whack, which I dont have the experience to fix yet, but this is the task ahead of me without getting to change or fix our structure:
in the universe has 1000+ tables.
need--> Some of those tables have fields that contain a value that has to be changed.
The only thing I have to go on is the column name will contain 'EMP'... but there is no specific naming convention for the column names.
When I search on:
select * from all_tab_columns where column_name like UPPER('%EMP%')
It returns 750 rows. (So 750 rows = 750 columns in 500 different tables (some tables have 2 or more columns in it))
tables names are random (table1, table2, etc).
columns names are random with EMP in it (column1,column2,etc).
I have 75 possible field values that I need to check each of those 750 columns for.
Maybe this is too messy, but I'm looking at subqueries, joins, arrays, cursors, etc, anything to minimize the amount of work I have to do.
I think this is too much to do a join with, but that seems to be what all the documentation is pointing me to.
can you point me to a simple example of what i could
write?
the logic i see it would be
run the select statement to grab the column names that meet EMP.
one at a time, search each column in the corresponding table for the 75 values.
return the results of rows for each column/table that meet one of the 75 unique values.
I'll have to also update each of the 75 values to (used to be values 1, 2, 3 ... to new values X1, X2, X3, etc.)
Any help at all would be very helpful,
aspiring pl/sql programmer but having a rough time of it

I think you're looking to do something like the following pseudocode:
BEGIN
    FOR tblrec IN (SELECT table_name, column_name
                     FROM all_tab_columns
                    WHERE column_name LIKE '%EMP%')
    LOOP
        FOR rec IN (SELECT ROWID
                      FROM tblrec.table_name
                     WHERE REGEXP_LIKE(tblrec.column_name, '(expr1|expr2|...)')
        LOOP
            DBMS_OUTPUT.PUT_LINE(
                'Found expression on ROWID ' || rec.rowid
                || ' in column ' || tblrec.column_name
                || ' on table ' || tblrec.table_name);
        END LOOP;
    END LOOP;

But i implemented in case too ,its taking more time to return the value while using case statement.So the issue is not with CASE its with the SELECT Statement. What you have to do is Isolate your SELECT statement and try to tune it for performance.
To do that i would suggest you to read the folloing threads which could be of good use.

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
Rede

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;
