Query related to database tables

Hi,
Im having a requirement wherein i would like to create one ztable and the purpose is only to get the fields but not the values for the same. Bez, with the help of these fields in ztable and developing some logic and it shld be dynamic based on the no of fields appended into ztable.
To be clear, can i write a select query only to get the fields from the table but not the values ( in this no way i will get the values bez i won't insert any records for the same).
I thnk im clear from my end.
Thanks
rohith

To get the fields, you can write the query like this too :
tables: dd03l.
data: begin of itab occurs 0,
fieldname like dd03l-fieldname,
end of itab.
*parameters: p_tab like dd03l-tabname.
select fieldname from dd03l into table itab where tabname = 'VBAK'.
LOOP AT ITAB.
WRITE:/ itab-fieldname.
ENDLOOP.

Query related to Internal Table

Hi ,
I have a small query related to internal table , can we dump millions of records to an internal .
The actual requirment is like i need to develop a report in BI side where i have to dump records into an internal table from PSA tables without filtering .
Can we do so ....
or do we have any other option to dump the data to an internal tables .
need some tips on the same .
Thanks ,
VInay.

Hello Vinay,
I believe the following extract will give you a brief idea on the size limitations for an internal table.......
Internal tables are dynamic data objects, since they can contain any number of lines of a particular type. The only restriction on the number of lines an internal table may contain are the limits of your system installation. <u><i>The maximum memory that can be occupied by an internal table (including its internal administration) is 2 gigabytes. A more realistic figure is up to 500 megabytes. An additional restriction for hashed tables is that they may not contain more than 2 million entries.</i></u>
Hope it proved useful

MV Incremental Refresh on join query of remote database tables

Hi,
I am trying to create a MV with incremental refresh option on a join query with 2 tables of remote database.
Created MV logs on 2 tables in the remote database.
DROP MATERIALIZED VIEW LOG ON emp;
CREATE MATERIALIZED VIEW LOG ON emp WITH ROWID;
DROP MATERIALIZED VIEW LOG ON dept;
CREATE MATERIALIZED VIEW LOG ON dept WITH ROWID;
Now, trying to create the MV,
CREATE MATERIALIZED VIEW mv_emp_dept
BUILD IMMEDIATE
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE1/(24*15)+
WITH PRIMARY KEY
AS
SELECT e.ename, e.job, d.dname FROM emp@remote_db e,dept@remote_db d
WHERE e.deptno=d.deptno
AND e.sal>800;
Getting ORA-12052 error.
Can you please help me.
Thanks,
Anjan

Primary Key is on EMPNO for EMP table and DEPTNO for DEPT table.
Actually, I have been asked to do an feasibility test whether incremental refresh can be performed on MV with join query of 2 remote database tables.
I've tried with all combinations of ROWID and PRIMARY KEY, but getting different errors. From different links, I found that it's possible, but cannot create any successful testcase anyway.
It will be very much helpful if you can correct my example or tell me the restrictions in this case.
Thanks,
Anjan

Help with SQL Query Involving Three Database Tables

Hi,
My SQL is very rusty since I have not touched it in over one year.
I was given an SQL question in a job interview and I am curious to know the right answer.
This was a pre-prepared written test and the interviewer did not know the answer.
There are three database tables: STUDENTS, COURSES and STUDENT_COURSES
Table STUDENTS has STUDENT_ID and STUDENT_NAME columns.
Table COURSES has COURSE_ID and COURSE_DESCRIPTION columns.
Table STUDENT_COURSES has columns STUDENT_ID and COURSE_ID.
Provide a query that returns all the students that are enrolled in all the courses.
Thanks,
Avi.

It is probably good to say that this task may be solved such way, if database normalized and there are references
Basically here just is a variant of your solution
DROP TABLE student_course;
DROP TABLE student;
DROP TABLE course;
CREATE TABLE student
(student_id NUMBER(9) PRIMARY KEY,
student_name VARCHAR2(30));
CREATE TABLE course
(course_id NUMBER(9) PRIMARY KEY,
dscr VARCHAR2(100));
CREATE TABLE student_course
(student_id NUMBER(9),
course_id NUMBER(9));
ALTER TABLE student_course
ADD CONSTRAINT pk_st_crs PRIMARY KEY
(student_id, course_id);
ALTER TABLE student_course
ADD CONSTRAINT fk_student
FOREIGN KEY (student_id)
REFERENCES student(student_id);
ALTER TABLE student_course
ADD CONSTRAINT fk_course
FOREIGN KEY (course_id)
REFERENCES course(course_id);
INSERT INTO student
     VALUES (1, 'NAME1');
INSERT INTO student
     VALUES (2, 'NAME2');
INSERT INTO student
     VALUES (3, 'NAME3');
INSERT INTO course
     VALUES (101, 'Desc 1');
INSERT INTO course
     VALUES (102, 'Desc 2');
INSERT INTO course
     VALUES (103, 'Desc 3');
INSERT INTO student_course
     VALUES (1, 101);
INSERT INTO student_course
     VALUES (1, 102);
INSERT INTO student_course
     VALUES (2, 101);
INSERT INTO student_course
     VALUES (2, 103);
INSERT INTO student_course
     VALUES (3, 101);
INSERT INTO student_course
     VALUES (3, 102);
INSERT INTO student_course
     VALUES (3, 103);
COMMIT ;
WITH st_crs_cnt AS
     (SELECT   student_id,
               COUNT (*) tot
          FROM student_course
      GROUP BY student_id)
SELECT sc.student_id,
       sc.tot
FROM st_crs_cnt sc
WHERE sc.tot = (SELECT COUNT (*) FROM course);

Query in abap database tables

hello Experts,
Is there any System table to get the Year.For Example to get the Month we can use T247 database table like this any system table to get year.
thanks
regards,
Ashok.

Sorry can you explain what do you mean to get year ??
The below would give you the year.
Year = Sy-datum(4).
If you wish to convert it into words you can use SPELL_WORD and make sure to use currency with zero decimails..in that case it would return two thousand six in words.

Query related to external table authentication

Hi Gurus,
I am new to OBIEE. When we login to the Oracle Business intelligence, we used to give user as Administrator and password as Administrator.
At this point, can we authentication the userid and password which is stored in external table in a users schema?
~ John

"Administrator" will always be a user which is registered in the repository. All other users can be authenticated by external table authentication.
You can create an init block which sets the USER system variable by
SELECT user FROM users WHERE user = ':USER' and password = ':PASSWORD'

How an INDEX of a Table got selected when a SELECT query hits the Database

Hi All,
How an Index got selected when a SELECT query hits the Database Table.

The fields in the INDEX of the Table EKPO should be in the same sequence as in the WHERE clasuse?
Regards,
Viji

Hi,
You minimize the size of the result set by using the WHERE and HAVING clauses. To increase the efficiency of these clauses, you should formulate them to fit with the database table indexes.
Database Indexes
Indexes speed up data selection from the database. They consist of selected fields of a table, of which a copy is then made in sorted order. If you specify the index fields correctly in a condition in the WHERE or HAVING clause, the system only searches part of the index (index range scan).
The primary index is always created automatically in the R/3 System. It consists of the primary key fields of the database table. This means that for each combination of fields in the index, there is a maximum of one line in the table. This kind of index is also known as UNIQUE. If you cannot use the primary index to determine the result set because, for example, none of the primary index fields occur in the WHERE or HAVING clause, the system searches through the entire table (full table scan). For this case, you can create secondary indexes, which can restrict the number of table entries searched to form the result set.

Need to insert into NVARCHAR2 column in a database table

I need to insert into a table with column type NVARCHAR2(2000) in java.
Cant use normal setString on that column. How can I do this using PreparedStatement in Java?

The scenario is:
I have to read a CSV file which contains a column in Urdu language, and show it on the JTable first.
Then I have to import the JTable contents into a database table.
Database Table structure is:
CREATE TABLE IMPORT_TMP (
ctype          VARCHAR2(3),
urdu_name NVARCHAR2(2000)
);My java code which inserts into the database table is:
                Vector dataVector = tableModel.getDataVector();
                rowVector = (Vector) dataVector.get(row);
              cType = "";
                if (rowVector.get(INDEX_BANK) != null) {
                    cType = rowVector.get(INDEX_CTYPE).toString();
                urduName = "";
                if (rowVector.get(INDEX_URDU_NAME) != null) {
                    urduName = rowVector.get(INDEX_URDU_NAME).toString();
                statementInsert.setString(1, cType);
                statementInsert.setString(2, urduName);I also applied Renderer on the table column, my renderer class is:
public class LangFontRenderer extends JLabel implements TableCellRenderer {
    private Font customFont;
    public LangFontRenderer(Font font) {
        super();
        customFont = font;
        System.out.println("font = " + font.getFontName());
        this.setFont(font);
    @Override
    public Component getTableCellRendererComponent(JTable table,
            Object value, boolean isSelected, boolean hasFocus, int row, int column) {
        if (value != null) {
            if (value instanceof String) {
                setText((String) value);
                return this;
        return this;
    @Override
    public Font getFont() {
        return customFont;
    // overriding other methods for performance reasons only
    @Override
    public void invalidate() {
    @Override
    public boolean isOpaque() {
        return true;
    @Override
    public void repaint() {
    @Override
    public void revalidate() {
    @Override
    public void validate() {
}I applied the renderer on the column as:
        TableColumn col = IATable.getColumnModel().getColumn(INDEX_URDU_NAME);
        LangFontRenderer langRenderer = new LangFontRenderer(new java.awt.Font("Urdu Naskh Asiatype", 0, 11));
        col.setCellRenderer(langRenderer);It does not give any error but when i query on the database table it does not show the column data in Urdu language.
Also it does not show the correct value on JTable column, some un-identified symbols.
Furthermore when I open the CSV file in notepad, it shows the correct language in that column, as I have installed the Urdu language and font on my system.

Inner join query used with 7 Database tables

HI All,
In a report they used the Inner join Query with 6 Data base table..now there is a performance issue with at query.
its taking so much of time to trigger that query. Please help how to avoid that performance issue for that.
In that 2 database tables containing lakhs of records..
According to my knowledge it can be avoided by using secondary indexs for those 2 database tables..
and by replacing the Inner join Query with FOR ALL ENTRIES statement.
i want how to use the logic by using FORALL ENTRIES statement for this..
So, please give you proper suggestion to avoid this issue..
Thanking you.
Moderator message: Please Read before Posting in the Performance and Tuning Forum
Edited by: Thomas Zloch on Oct 16, 2011 10:27 PM

Hi,
And what do you mean with "they used"? If "SAP used" then yo will need to ask a SAP for note
FOR ALL ENTRIES is quite good described in help. Please search forum also.
Without query it won't be possible to tell how it can be optimized, however you can try to use SE30/SAT and ST05. Maybe it will help you.
