How to make Column and Row headers bold in Web template?
Hi Experts,
I have a web application with a query in it. Now I would like to know how I could make the column and row headers of this webquery in bold font? I havent found any properties in any web item to make this possible. It looks like the only way to do this is CSS, but i dont have any experience with style sheets.
Are there easier ways to do this?
Thanks in advance.
Rgds,
RichardTried this for fun using JavaScript. It appears to work, but is pretty much a hack, and I didn't test it thoroughly.
Place this in a function that is called during onload of the page:
var eleid='';
for(var ct=0;ct<1000;ct++) {
eleid='ANALYSIS_interactive_mc'+ct+'_tv';
if (document.getElementById(eleid)) {
if(document.getElementById(eleid).parentNode.className=='urLayoutPadless') {
document.getElementById(eleid).style.fontWeight='bold'; -
Hi,
I have 6 columns and 4 rows and i want to convert it into 6 rows and 4 columns and want to display in table control.
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. -
Dear all....I need to convert all columns into rows in a table. For example table has following columns:
Emp_Cod........Val1......Val2......Val3
1 a b c
Now I wish that each column should display as a value like:
Emp_Cod........Val1
1 a
1 b
1 c
Now the one way to solve this job is to write a union statement for each column but for this I'll have to write equal number of select statements as there are columns.
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)
2 select*from t unpivot(v for c in(val1,val2,val3));
EMP_CODE C V

Hello,
I am trying to build and SQL to convert columns from multiple rows to the all rows - see below test data and result expected:
CREATE TABLE XX_TEST(NAME VARCHAR2(10),A1 VARCHAR2(10),A2 VARCHAR2(10), A3 VARCHAR2(10),A4 VARCHAR2(10),A5 VARCHAR2(10));
INSERT INTO XX_TEST VALUES('LIST','A','B','C','D','E');
INSERT INTO XX_TEST VALUES('L1','1',NULL,'3',NULL,NULL);
INSERT INTO XX_TEST VALUES('L2','1','5','4',NULL,NULL);
COMMIT
SELECT * FROM XX_TEST;
Result expected:
NAME is Column from table XX_TEST but COLUMN and VALUE are the columns converted to rows-
NAME COLUMN VALUE
L1 A1 1
L1 A2 NULL
L1 A3 3
L1 A4 NULL
L1 A5 NULL
L2 A1 1
L2 A2 5
L2 A3 4
L2 A4 NULL
L2 A5 NULL
Thanks
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.
