Index using in select statement

Hi All ,
i'm new using pl/sql and i have a doubt , i have the following query and want to use index...but use two different tables..how can i do that?
SELECT /*+ index(TA TABLE1) */
TA.USER , TA.DATE ,TB.DATA
FROM TABLEA TA , TABLE B
WHERE TA.USER=TB.USER
in this case ..how i can use index to both tables...TABLE A and TABLE B?
Thanks in advance.
rgds,

At best with your current query you can use an index on just one table while doing a full table scan on the other since you have no other limiting criteria. It doesn't make sense to use indexes on both tables.
If one table is significantly smaller than the other, better to do the full table scan on the smaller table and use an index on the other one.
Again, full table scans is not a bad thing. It depends on how large the table is.
As Eric suggested, in most cases let the compiler determine when and which index to use. You should be using a hint only when absolutely necessary when you have some information about the data being searched for that the compiler could not know.

Problems with Hints in abap code to use an index in a Select statement

Hi,
I want to use an especific index in a select statement but I can´t get it. I use de next statement:
SELECT ltaklgnum ltaktanum ltakvbeln ltaptapos ltapnltyp ltappvqui
       FROM ltak AS ltak INNER JOIN ltap AS ltap
                        ON ltaktanum = ltaptanum

         AND ltak~kquit EQ ' '
         AND ltak~queue EQ ip_queue
         %_HINTS DB2 ''.
We have DB2 for Linux Unix and Windows 9.5 as DB system.
How can I fix this?
Thanks a lot.

The DB2 for Linux Unix and Windows is coded DB6 for SAP and not DB2

FROM ltak AS ltak INNER JOIN ltap AS ltap
ON ltak~tanum = ltap~tanum

    AND ltak~queue EQ ip_queue
%_HINTS DB6 '<IXSCAN TABLE=''LTAP'' INDEX=''"LTAP~M"'' />'.
In note 868888 there is a sample for a join.
SELECT A~TABSPACE
FROM TADB6 AS A

Use two secondary indexes in a select statement

hi, i want to use two secondary indexes in a select statement.
how can i do it?

Hello,
To do it use the WHERE stm in the same order as the secondary stm is on SE11....To check if the index is used go to tcode ST05.
example
select * from ztable
WHERE BUKRS EQ 'BUK1' AND
ZFIELD EQ 'BOY'.
on se11 on the ZTABLE indexes setion must have a secondary index with
BUKRS and
ZFIELD.
BYE!!
Hope this helps!!

Index not being used in Select statement

Friends
I have the following SQL statement:
SELECT
a.acct,
a.date_field,
UPPER(b.feegroup) feegrp,
SUM (a.fee1) fee1,
SUM (a.fee2) fee2,
SUM (a.fee3) fee3
FROM table1 a, table2 b
WHERE 1 = 1
AND a.fee_id = b.fee_id
GROUP BY a.acct, a.date_field, b.feegroup;
Both the tables have index on fee_id column. When I run the explain plan for this statement, I am getting the following output:
Operation | Option | Object Name | Position
SELECT STATEMENT | | | 560299
HASH | GROUP BY| |1
TABLE ACCESS | FULL| table2 | 1
TABLE ACCESS | FULL| table1 | 2
Why Oracle is not using the index?
Edited by: darshilm on Dec 10, 2009 3:56 PM

The proposed plan is the optimal according to your current conditions in the "where clause" where you have only the equality join condition and therefore the CBO can use HASH JOIN. Using any kind of index access would just increase the amount of required work unless you would add some very restrictive conditions which will select rows from relatively small amount of blocks. Here I have to mention that what really counts in the CBO cost calculation is the amount of blocks accessed and not the number of rows. The "currency" for I/O in Oracle is a block and not a row. CBO always uses an assumption that there is nothing in the buffer cache and it will have to perform a physical read for every block.
How many blocks will actually be accessed depends on the data distribution. It can happen that every single row that you have to retrieve resides in a different block and although you access only 1000 rows out of a million row table you would have to visit almost every block of that table. For such a situation a FULL TABLE SCAN is the best access path and Oracle will use multiblock I/O for that. On the other side you can have those 1000 rows only in a few blocks and then the index access would be the most appropriate one. For index access Oracle uses single block I/O. Usually the actual situation is somewhere between this two extreme situations. But you can run some tests by yourself and see when an index access will be replaced by a full table scan while you will make your predicates less selective.

When is a secondary index used (in select or where)

HI All,
We are confused (and new to ABAP) on the various postings on SDN concerning this topic. Replies seem to vary.
We have the following select statement:
SELECT date1 FROM table2
WHERE material (from a stored internal table) = material-table2
AND order (from a stored internal table) = order-table2
AND delivery method (from a stored internal table) = specific value of table2.
For a second index to be created, would we create the index for only date1 (since it's the only field we are selecting from table 2) or an index with date1, material, order, delivery method or just what's in the WHERE clause of material, order and delivery method?
How can you be sure that an index will be used?
Thank you!

> We are confused (and new to ABAP)
seem you are very very new.
Your question is actually not ABAP indexes etc are SQL and can be found in many textbooks also on Wiki pages. ABAP uses SQL, but does not change much.
The use index is determined nearly only by the WHERE clause. You want to know the phone number of somebody and you know the name and the address. The Index uses the name and the address as a telephone book. The phone number comes from the table not the index! This is not the secondary index, but the primary index.
If you search in the internet for phone number, then you can use also a secondary index, i.e. you know only the complete address but not the name. A phone book would not help here.
Which index is used, if often very simple as in the example, but can become very difficult. That is done by a sophisticated program of the database, the optimizer. Check other resoucres for details.

ORA-00911: invalid character using multiple select statements

I am getting an ORA-00911: invalid character error when trying to execute 2 select statements using ODP.NET.
cmd.CommandText = "select sysdate from dual;select sysdate from dual;";
cmd.Connection = conn;
cmd.CommandType = System.Data.CommandType.Text;
conn.Open();
OracleDataReader dr = cmd.ExecuteReader();
This works in SQL server but for some reason it appears this does not work in Oracle?
If this is the case what is a vaiable workaround? Wrapping the 2 statements in a transaction?
Seems strange that you can't return multiple result sets using in-line sql statements.

Oracle doesn't support passing multiple statements like that, and this is unrelated to ODP.NET.

How to use a select statement with chinese characters?

I am currently developing a java servlet<using tomcat 4.x> which allows me to use select statement to retrieve results from the Microsoft SQL Server 2000 database. I am using a simple form to get the parameter for querying. The main problem i'm facing is that there are chinese information in the SQL database, but i can't retrieve it through the sql statement with the chinese characters input<thru the form with the help of NJ STAR>in the WHERE condition. When i execute the statement, it returns me no results even though the rows are present in the database.
Does anyone have the solution to using chinese words in the WHERE clause of the select statement to retrieve results with columns which contains chinese characters? Please help me. Thanks everyone. :)
PS: when i cut and paste those characters in the sql database and paste onto java.. it is ??? in questionmarks.. but when i paste them into excel 2000.. its shown as chinese chars again..
please heelppp~~

Greetings,
PS: when i cut and paste those characters in thesql
database and paste onto java.. it is ??? in
questionmarks.. but when i paste them into excelThis is why the SELECT is not returning any results.
You need to set the character encoding set on your
statement and parameters for the characters to be
properly translated. Refer to the charsetName
parameter in the String class constructor in your API
docs and also to
$JDK_DOCS/guide/intl/encoding.doc.html in your JDK
documentation.
2000.. its shown as chinese chars again..Because Office programs are performing the same kind
of character translation with the appropriate MS APIs.
please heelppp~~Regards,
Tony "Vee Schade" Cookis it possible for you to show me some coding examples? i don't really understand what is to be done in order to set the char set and what does it really do.. tried reading up but still dun understand.. :(
pardon my shallow knowledge of java..
ok..
The thing is when i used an insert statement with chinese characters of GBK format hardcoded into the java servlet and then i use the insert statement to insert the chars into the database, it cannot be seen as a chinese word when i off the NJStar. and then it can be searched out with my current form of servlet.. below is my coding of the servlet..

with the above servlet i created, i can search out the data in the database which i've inserted through the insert statement. I still can't search for things i've keyed into the database directly using NJStar..
thank you so much for helping.. really hope any one else who knows the answer to this will reply too... thank you all so much...

How can i retrieve the output of procedure using a select statement ?

Hi every one.
this mite be dumm ?
how can i use the output of the a procedure containing multiple rows of data in a select statement ?

This is not a SQL Developer question. You should ask it in the SQL and PL/SQL forum.
The short answer is you can't. Sounds is if you are trying to use MSSQL techniques in oracle. Learn oracle techniques

According to your description, you want to write multiple select statements in a procedure, then use the procedure as dataset in the report, right?
According to my knowledge, when we write multiple select statements in a procedure, we have to create relationship between these select statements, otherwise it will only return the first one query's fields. If you are using SSRS 2008 R2, you can use Lookup
function to display these fields from different datasets on one data region control, but the prerequisite is that you must have one common field. For more information about lookup function, please see:
http://msdn.microsoft.com/en-us/library/ee210531.aspx
If all these solution you cannot achieve due to your special condition, the last workaround is to use subreport to display all the fields together.
If you have any more questions, please feel free to ask.
Thanks,

SELECT OPTIONS use in select statement

hi,
I have defined my selection screen in the main program.
selection-screen begin of screen 0101 as subscreen.
selection-screen begin of block b1.
select-options: S_KUNNR for KNA1-KUNNR,
selection-screen end of block b1.
selection-screen end of screen 0101.
then in an include in the same module pool, i try to use this in select statement
SELECT * INTO CORRESPONDING FIELDS OF XXX FROM ZPPP WHERE KUNNR IN S_KUNNR.
I get an error saying " the IN operator with S_KUNNR is neither followed by an internal table nor by a valuelist "..what does this mean ?
thks

Check the sample code...
REPORT ztest_mod.
DATA: kunnr TYPE kunnr.
* Custom Selection Screen 0200
SELECTION-SCREEN BEGIN OF SCREEN 0200 AS SUBSCREEN.
SELECT-OPTIONS: s_kunnr FOR kunnr.
SELECTION-SCREEN END OF SCREEN 0200.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_kunnr-low.
BREAK-POINT.
START-OF-SELECTION.
"in this screen i have a button with function code 'SEARCH'
" and a subscreen area with name sub
CALL SCREEN 100.
*&      Module STATUS_0100 OUTPUT
MODULE status_0100 OUTPUT.
SET PF-STATUS 'STATUS'.
ENDMODULE.                    "status_0100 OUTPUT
*&      Module USER_COMMAND_0100 INPUT
MODULE user_command_0100 INPUT.
DATA: it_kunnr TYPE TABLE OF kna1.
CASE sy-ucomm.
    WHEN 'SEARCH'.
      SELECT * FROM kna1
      INTO TABLE it_kunnr
      WHERE kunnr IN s_kunnr.
    WHEN 'BACK'.
      LEAVE TO SCREEN 0.
ENDCASE.
ENDMODULE.                    "user_command_0100 INPUT
in the flow logic..
PROCESS BEFORE OUTPUT.
MODULE status_0100.
CALL SUBSCREEN sub INCLUDING sy-repid '0200'.
PROCESS AFTER INPUT.
MODULE user_command_0100.

Bind variables are not used in select statement

Hello all of you,
I have two parameters in Report 6i.
1) Department
2) Section
There are many section in a single department. Both parameters are selected from list. The list for department name is as follows -
select deptname from department_master order by deptname
It works very well. The value is stored in :p_dept_name.
I want to display section of selected department only using following code :-
select sectname from section_master a, department_master b where a.deptcode = b.deptcode and b.deptname = :p_dept_name
The value is stored in :p_sect_name.
But it does not work. bind variables are not allowed in select statement, then how can I do this???
Please suggest me.
Thanx,
Regards,

Vikas,
the forum is full of threads about that.
Dependent Parameters in Reports are possible out-of-the-box in Reports.
If you're running your report on the web, have a look at Metalink Note:185951.1

Function returning cursor to be used in select statement

I have written a function which returns a cursor. I want to use this in a select statement to display rows. How to do this.
Eg : function - test_fn return sys_refcursor. (returns empno, empname, deptname)
select test_fn from dual
This should return
empno empname deptno
1 name1 dept1
2 name 2 dept2
....

Try This::
SCOTT@xe_144>variable c refcursor
SCOTT@xe_144>CREATE OR REPLACE FUNCTION get_nm
2     RETURN sys_refcursor
3 AS
4
5     c sys_refcursor;
6 BEGIN
7
8     open c for 'SELECT ENAME , SAL FROM EMP';
9
10     RETURN c;
11 END;
12 /
Function created.
SCOTT@xe_144>select get_nm into :c from dual;
GET_NM
CURSOR STATEMENT : 1
CURSOR STATEMENT : 1
ENAME             SAL
