Convert columns to rows by a select query
I have a table with 10 columns. Pk is combination of 3 columns, let us say A, B and C. I need a select query which returns 7 rows with four columns each let us say A,B,C and D where D contains the value of non PK column. i.e. for first row, D will contain value of fourth column of the table, for second row, D will contain fifth column of the table and so on.
Please help.
Maybe NOT TESTED!

How to get number of rows return in SELECT query
i'm very new in java, i have a question:
- How to get number of rows return in SELECT query?
(i use SQL Server 2000 Driver for JDBC and everything are done, i only want to know problems above)
Thanks.make the result set scroll insensitve, do rs.last(), get the row num, and call rs.beforeFirst(), then you can process the result set like you currently do.
String sql = "select * from testing";
PreparedStatement ps =
con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
ResultSet rs = ps.executeQuery();
rs.last();
System.out.println("Row count = " + rs.getRow());
rs.beforeFirst();~Tim
NOTE: Ugly, but does the trick. -
Needs help to retrive the last row in a select query without using rownum
Hi ,
i need to retrive the last row from the select sub query without using rownum.
is there any other way to retrive the last row other than the below query.
is that the ROWNUM=1 will always retrive the 1 row of the select query ?
select from*
*(select ename from employee where dept_id=5 order by desc) where rownum=1;*
Please advise.
thanks for your help advance,

you can select the PRIOR values to get the parent details if you want...

BSHi,
Thanks for posting the sample data in such a useful form!
Whenever you post a question, you should always say what version of Oracle you're using, too.
Displaying multiple columns from one row as one column on multiple rows is called Unpivoting .
In Oracle 11, you can use the SELECT ... UNPIVOT feature to do that.
In any version of Oracle, you can cross-join your table to a Counter that has as many rows as your original table has columns to be unpivoted.
In this problem, we need a self-join of the unpivoted data, to join the rows with name='LIST' to every other row.
WITH cntr AS
SELECT LEVEL AS n
FROM dual
CONNECT BY LEVEL <= 5
, unpivoted_xx_test AS
SELECT x.name
, 'A' || c.n AS col
, CASE c.n
WHEN 1 THEN x.a1
WHEN 2 THEN x.a2
WHEN 3 THEN x.a3
WHEN 4 THEN x.a4
WHEN 5 THEN x.a5
END AS val
FROM cntr c
CROSS JOIN xx_test x
SELECT u.name
, u.col
, l.val AS val1
, u.val AS val2
FROM unpivoted_xx_test l
JOIN unpivoted_xx_test u ON l.col = u.col
WHERE l.name = 'LIST'
AND u.name != 'LIST'
ORDER BY name
, col
;Output:
NAME COL VAL1 VAL2
L1 A1 A 1
L1 A2 B
L1 A3 C 3
L1 A4 D
L1 A5 E
L2 A1 A 1
L2 A2 B 5
L2 A3 C 4
L2 A4 D
L2 A5 EThe query above uses some features that were new in Oracle 9, but the basic strategy will work in earlier versions.
If your columns don't have such regular names (A1, A2, A3, ...) then you can use another CASE expression to derive unpivoted_xx_test.col. -

Now I wish that each column should display as a value like:

1 b
1 c

What I need that is there anyway to write minimum code for this job, is there any alternate way???SQL> with t as(select 1 emp_code, 'a' val1, 'b' val2, 'c' val3 from dual)

plz help me in this ....Hi Kinjal,
Question is not clear. You want to change the internal table values with 6 columns & 4 rows to 4 columns & 6 rows?
If my understanding is correct, check the bleow logic:
loop at itab1.
case sy-tabix.
when 1.
itab2-c1 = itab1-c1.
append itab2.
itab2-c1 = itab1-c2.
append itab2.
itab2-c1 = itab1-c3.
append itab2.
itab2-c1 = itab1-c4.
append itab2.
itab2-c1 = itab1-c5.
append itab2.
itab2-c1 = itab1-c6.
append itab2.
when 2.
itab2-c2 = itab1-c1.
modify itab2 transporting c2 index 1.
itab2-c2 = itab1-c2.
modify itab2 transporting c2 index 2.
itab2-c2 = itab1-c3.
modify itab2 transporting c2 index 3.
itab2-c2 = itab1-c4.
modify itab2 transporting c2 index 4.
itab2-c2 = itab1-c5.
modify itab2 transporting c2 index 5.
itab2-c2 = itab1-c6.
modify itab2 transporting c2 index 6.
when 3.
itab2-c3 = itab1-c1.
modify itab2 transporting c3 index 1.
when 4.
itab2-c4 = itab1-c1.
modify itab2 transporting c4 index 1.
Endloop.
Finally you will get 6 rows with 4 coulmns. -
