How to write Sql statement for M:M relationship set?

If theres two Entity sets "Department" and "Employee".....
Department Entity contains this attribute dno,dname,address etc and
"Employee" entity contain attribute like Empno,Empname,date,time etc
and theres Many to Many relationship between Employee and Deapartment Entity set,i.e.each employee can work in any department, and each department has at least one employee (Many to Many relationship)
What should be the SQL statement to create table for Many to Many relationship sets for Employee and Department set..
Any helps will be appreciated.
Femi

create 3 tables: employee, department and empdept
in the empdept table you reference foreign keys from the 2 other tables. so if my employee id was 42 and I work for departments 1,2 and 3, this table would look like this:
emp_fk | dept_fk
42           1
42           2
42           3

    I need to check whether SGTXT contains BELNR value.
    SGTXT is a text field and It should be matched with BELNR
    How to write select statement for this.
    Select AUGBL AUGDT into t_BSAD
    from BSAD

    concatenate '%' belnr '%' into temp.
    Select AUGBL AUGDT into t_BSAD

  • How to write sql query for counting pairs from below table??

    Below is my SQL table structure.

    100006 Simran Left NULL NULL 100003
    100007 Raman Right NULL NULL 100003
    100008 Vijay Left NULL NULL 100004
    It is a binary table structure.. Every user has to add two per id under him, one is left_leg and second is right_leg... Parent_id is under which user current user is added.. Hope you will be understand..
    I have to write sql query for counting pairs under id "100001". i know there will be important role of parent_id for counting pairs. * what is pair( suppose if any user contains  both left_leg and right_leg id, then it is called pair.)
    I know there are three pairs under id "100001" :-
    1.  100002 and 100003
    2.  100004 and 100005
    3.  100006 and 100007
        100008 will not be counted as pair because it does not have right leg..
     But i dont know how to write sql query for this... Any help will be appreciated... This is my college project... And tommorow is the last date of submission.... Hope anyone will help me...
    Suppose i have to count pair for id '100002'. Then there is only one pair under id '100002'. i.e 100004 and 100005

    Sounds like this to me
    DECLARE @ID int
    SET @ID = 100001--your passed value
    SELECT left_leg,right_leg
    FROM table
    WHERE (user_id = @ID
    OR parent_id = @ID)
    AND left_leg IS NOT NULL
    AND right_leg IS NOT NULL

  • Pass ORG_ID as sql statement for parameter in request set

    We are in a multi-org environment. We are running the request PRC: Generate Draft Revenue for a Single Project as part of the request set. We want the request to automatically fill in the open pa period as the accrue through date. We have been using the SQL Statement below as the value for the accrue through date parameter.
    select end_date
    from pa_periods_all
    where status = 'O'
    and current_pa_period_flag = 'Y'
    Unfortunately that does not limit to a specific company. We a company that still have DEC-05 while another has an open period of JAN-06. This is causing the program fits. How do I pass the org_id to the request? [in beginners terms please]
    Thanks.
    Anne

    No idea what might be wroong without more info...
    Do some output. Test the ${params.id} variable passed to the second jsp. If that is correct, then error is in the select statement or display of jsp2. If it is correct the error comes from jsp1.
    If I have to guess, then I would say the error comes from JSP1, and the ${row.vac_id} should only be called once. In which case I would do something like this:
    //in jsp 1
                <c:forEach var="row" items="${results.rows}"  varStatus="counter"  >
                    <c:set var="vac_id" value="${row.vac_id}" scope="page"/>
                    <tr>
                        <td>${vac_id}</td>
                        <td><a href="vacancydetails.jsp?id=${vac_id}">More</a></td>But that is a guess only...
    Errr... Hold on to that as reference, but the it is entirely likely that I misspelled ${params.id} It may be ${param.id} I forget and away from my machine right now...

  • How to write SQL hints for this query?

    The query is like:
    select * from foo, t
    where foo.name in
    (select name from bar
    where id in (
    select id from car
    where date < sysdate
    and foo.a = t.b;
    I want the innermostsubquery 'select id from car ...' to be executed first, and the subquery 'select name from bar ...' to be execute second, and the outermost query 'select * from foo,t ...' to be executed the last. How can I write the Oracle sql hints to force the order?
    Thanks.

    user553560
    You might be able to create a large set of hints to force the access path you want - but unless you really know what you are doing with hints, you may find that your solution is very unstable (it might be luck rather than correctness that let's it work to start with).
    The difficulty in this query is the double layer of IN subqueries, so if you can rewrite the query, you might try manually unnesting as follows:
    select
         t1.*. t.*
    from
              select     
                   distinct t2.name
              from     t2
              where     t2.id in (
                        select     t3.id
                             from     t3
                        where     t3.dated < sysdate
         )     v,
         t1,
         t
    where
         t1.name = v.name
    and     t1.a = t.bDepending on your indexing and statistics, you may find that a simple /*+ unnest */ hint in the first subquery will be sufficient to do this for your. Again depending on the statistics you may find that you have to put extra hints into the above to make Oracle use the join method and indexes you think appropriate.
    N.B. The first step (as others have noted) is to check that your statistics are good before you start manipulating the code or using hints.

    Jeyakanthan

    Hi Jeyakanthan,
    here is an example (put the like statement into the where field)
    SELECT T0.CardCode, T0.CardName FROM OITM T0 WHERE T0.CardName Like '%%test%%'
    The %% sign is a wildcard. If you need start with write 'test%%' and otherwise ends with '%%test'. For contains you need '%%test%%'. You also could combinate this statements like 'test%%abc%%'. This means starts with test and contains abc.

  • Preparing Dynamic SQL statement for inserting in Pro*C

    Hi Friends,
    From quite some time i am struggling writing Dynamic SQL statement for dynamic insert and update in Pro*C.
    Can somebody go through my code and suggest me the rigth way of doing.
    Right now it throws an error saying " Error while updating ORA-00904: invalid column name "
    Please help me.
    Girish.
    int main()
    EXEC SQL BEGIN DECLARE SECTION;
    char *uid ="scott/tiger";
    static char sqlstmt[129];
    struct /* DEPT record */
    int dept_num;
    char dept_name[15];
    char location[14];
    } dept_rec;
    EXEC SQL END DECLARE SECTION;
    EXEC SQL WHENEVER SQLERROR DO sql_error();
    EXEC SQL CONNECT :uid;
    dept_rec.dept_num = 50;
    strcpy(dept_rec.dept_name,"ADMIN");
    strcpy(dept_rec.location,"IN");
    strcpy(sqlstmt,"UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num");
    EXEC SQL EXECUTE IMMEDIATE:sqlstmt;
    EXEC SQL COMMIT;
    exit(0);
    void sql_error()
    printf("\nError while updating %s",sqlca.sqlerrm.sqlerrmc);
    EXEC SQL ROLLBACK;
    }

    A bit rusty here but this is how I see it.
    Think of it this way ..
    all Oracle is going to see is:
    UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num
    Its NOT going to know what dept_rec.dept_name is or dept_rec.dept_num is ..
    it doesnt go back and fill in those values.
    You need something like
    strcpy(sqlstmt,"UPDATE dept set DNAME = \"");
    strcat(sqlstmt,dept_rec.dept_name);
    strcat(sqlstmt,"\" where DEPTNO = ");
    strcat(sqlstmt,dept_rec.dept_num);
    printf(sqlsmt); # Just to be sure the update statement look right during testing.
