First of all please accept my apologize because of bad english. Also I'm new to this portal. I hope you'll help me for my questions.
I have two questions in Oracle.
How to find the number of '*' in each column on the table.
how to find the total number of '*' in the table.
The first question answer will be 2 2 3
The second one answer will be 7.
Thanks in advance to spend your valuable time to answer my questions!
C1 C2 C3
* 1 1
0 0 *
1 * *
* * *
Use conditional aggregation to count the stars in each column and for the total stars just add the previous totals:
SELECT COUNT(CASE c1 WHEN '*' THEN 1 END) AS c1_stars,
COUNT(CASE c2 WHEN '*' THEN 1 END) AS c2_stars,
COUNT(CASE c3 WHEN '*' THEN 1 END) AS c3_stars,
COUNT(CASE c1 WHEN '*' THEN 1 END)
+ COUNT(CASE c2 WHEN '*' THEN 1 END)
+ COUNT(CASE c3 WHEN '*' THEN 1 END) AS total_stars
FROM table_name
select sum(
case when c1='*' then 1
else 0 end) c1_cnt,
sum(
case when c2='*' then 1
else 0 end) c2_cnt,
sum(
case when c3='*' then 1
else 0 end) c3_cnt,
sum(
regexp_count(c1||c2||c3,'\*')) cnt_total_stars
from cnt_star;
C1_CNT
C2_CNT
C3_CNT
CNT_TOTAL_STARS
2
2
3
7
For the original table -
select * from cnt_star;
C1
C2
C3

you are using the SUM functiion and the GROUP BY is missing in the outermost SQL.
create table eom(year number(4), start_date date, net_rate_of_return number (10,4), id number(4))
SELECT year,
Net_TWRR_PERIOD,
ROUND (

FROM ( SELECT year,
ROUND (

FROM eom
WHERE id = '2' AND start_date < '09-September-2022')
GROUP BY year
ORDER BY year, Net_TWRR_PERIOD)
GROUP BY year, Net_TWRR_PERIOD
You have the outer query:
select year,
Net_TWRR_PERIOD,
round(
(
CASE
WHEN MOD(SUM(CASE WHEN Net_TWRR_PERIOD < 0 then 1 else 0 end ), 2)=1
THEN -1
ELSE 1
END
* EXP(SUM(LN(ABS(Net_TWRR_PERIOD))))
-1
) * 100,
2
)
from ( ... )
Which has a mix of aggregated columns and non-aggregated columns and you do not have a GROUP BY clause (in that outer query). You need to make sure all columns are either aggregated or contained in a GROUP BY.
So, change the outer query to:
select year,
Net_TWRR_PERIOD,
round(
(
CASE
WHEN MOD(SUM(CASE WHEN Net_TWRR_PERIOD < 0 then 1 else 0 end ), 2)=1
THEN -1
ELSE 1
END
* EXP(SUM(LN(ABS(Net_TWRR_PERIOD))))
-1
) * 100,
2
)
from ( ... )
GROUP BY year, Net_TWRR_PERIOD
The table like this.
bh sl productdate
a1 100 2022-1-1
a1 220 2022-1-2
a1 220 2022-1-3
a2 200 2022-1-1
a2 350 2022-1-2
a2 350 2022-1-3
The result like this.
bh sl_q(sl_before) sl_h(sl_after) sl_b(changeValue) productdate
a1 100 220 120 2022-1-2
a2 200 350 150 2022-1-2
Rules:the same field bh, when the field sl change,then get the record.
We can use a ROW_NUMBER trick here:
WITH cte AS (
SELECT t.*, ROW_NUMBER() OVER (PARTITION BY bh ORDER BY productdate) rn1,
ROW_NUMBER() OVER (PARTITION BY bh ORDER BY productdate DESC) rn2
FROM yourTable t
)
SELECT bh, MAX(CASE WHEN rn1 = 1 THEN sl END) AS sl_q,
MAX(CASE WHEN rn2 = 1 THEN sl END) AS sl_h,
MAX(CASE WHEN rn2 = 1 THEN sl END) -
MAX(CASE WHEN rn1 = 1 THEN sl END) AS sl_b
FROM cte
GROUP BY bh;
I have the following table - with a lot of rows -
ID A_1 B_1 A_2 B_2 A_3 B_3
-- ---- --- --- ---- --- ---
1 0 0 0 0 0 0
2 1 0 0 0 0 0
I need to get the following output table -
the rows will be ID, A_1, B_1 and so on.
ID A B
--- -- --
1 0 0
1 0 0
1 0 0
2 1 0
2 0 0
2 0 0
I tried with union, unpivot - I get only one row for each ID instead three.
How can I do this?
You have to use Union all to include the duplicate:
Demo
Result:
SELECT ID, A_1 A, B_1 B FROM TABLE1
UNION ALL
SELECT ID, A_2, B_2 FROM TABLE1
UNION ALL
SELECT ID, A_3, B_3 FROM TABLE1 ORDER BY ID;
select *
from t
unpivot (
(A,B)
for z in (
(A_1, B_1),
(A_2 , B_2),
(A_3, B_3)
)
);
Full test case with the results:
with t (ID, A_1, B_1, A_2 , B_2 , A_3, B_3) as (
select 1, 0 , 0, 0, 0, 0, 0 from dual union all
select 2, 1 , 0, 0, 0, 0, 0 from dual
)
select *
from t
unpivot (
(A,B)
for z in (
(A_1, B_1),
(A_2 , B_2),
(A_3, B_3)
)
);
Results:
ID Z A B
---------- ------- ---------- ----------
1 A_1_B_1 0 0
1 A_2_B_2 0 0
1 A_3_B_3 0 0
2 A_1_B_1 1 0
2 A_2_B_2 0 0
2 A_3_B_3 0 0
I have a query like
select count(1) from table_a where state=1;
it gives 20
select count(1) from table_a where state in (1,2);
it gives 25
I would like to have a query to extract percentage 80% (will be 20*100/25).
Is possible to have these in only one query?
I think without testing that the following SQL command can do that
SELECT SUM(CASE WHEN STATE = 1 THEN 1 ELSE 0 END)
/SUM(CASE WHEN STATE IN (1,2) THEN 1 ELSE 0 END)
as PERCENTAGE
FROM TABLE_A
or the following
SELECT S1 / (S1 + S2) as S1_PERCENTAGE
FROM
(
SELECT SUM(CASE WHEN STATE = 1 THEN 1 ELSE 0 END) as S1
,SUM(CASE WHEN STATE = 2 THEN 1 ELSE 0 END) as S2
FROM TABLE_A
)
or the following
SELECT S1 / T as S1_PERCENTAGE
FROM
(
SELECT SUM(CASE WHEN STATE = 1 THEN 1 ELSE 0 END) as S1
,SUM(CASE WHEN STATE IN (1,2) THEN 1 ELSE 0 END) as T
FROM TABLE_A
)
you have the choice for performance or readability !
Just as a slight variation on #schlebe's first query, you can continue to use count() by making that conditional:
select count(case when state = 1 then state end)
/ count(case when state in (1, 2) then state end) as result
from table_a
or multiplying by 100 to get a percentage instead of a decimal:
select 100 * count(case when state = 1 then state end)
/ count(case when state in (1,2) then state end) as percentage
from table_a
Count ignores nulls, and both of the case expressions default to null if their conditions are not met (you could have else null to make it explicit too).
Quick demo with a CTE for dummy data:
with table_a(state) as (
select 1 from dual connect by level <= 20
union all select 2 from dual connect by level <= 5
union all select 3 from dual connect by level <= 42
)
select 100 * count(case when state = 1 then state end)
/ count(case when state in (1,2) then state end) as percentage
from table_a;
PERCENTAGE
----------
80
Why the plsql tag? Regardless, i think what you need is:
(select count(1) from table_a where state=1) * 100 / (select count(1) from table_a where state in (1,2)) from dual

How to calculate the individual row percentages in SSRS
Thank you.
If you're not filtering your dataset, you could use the Dataset sum to get the overall total and use that as the denominator in your expression.
If your table is a matrix with the C1 - C8 all coming from one field, then your formula would just be:
=Sum(Fields!YourField.Value) / Sum(Fields!YourField.Value, "Dataset1")
If the C1 - C8 fields are in separate fields, you can use the same expression used for your total column as the numerator and then divide by the SUM of all the other fields.
=Sum(Fields!C1.Value + Fields!C2.Value + Fields!C3.Value + Fields!C4.Value + Fields!C5.Value + Fields!C6.Value + Fields!C7.Value + Fields!C8.Value)
/
Sum(Fields!C1.Value + Fields!C2.Value + Fields!C3.Value + Fields!C4.Value + Fields!C5.Value + Fields!C6.Value + Fields!C7.Value + Fields!C8.Value, "Dataset1"))
I will work on SQL rather on SSRS. Here is my approach. For SSRS here is the link.
DECLARE #YourTable TABLE
(
Col INT
,Col1 INT
,Col2 INT
,Col3 INT
)
INSERT INTO #YourTable VALUES
(1 , 20, 10, 15)
,(2 , 30, 12, 14)
,(2 , 22, 2, 4)
,(3 , 3, 10, 15)
,(5 , 5, 14, 14)
,(2 , 21, 32, 4)
SELECT * FROM #YourTable
; WITH CTE AS
(SELECT *,Col+Col1+Col2+Col3 AS SumCol FROM #YourTable)
SELECT *, CAST(SumCol*100.0 / SUM(SumCol) OVER() as DECIMAL(28,2)) FROM CTE
Here's another approach:
Create a row outside of the details group, above the first row of data.
Populate a Textbox in the new row =Sum(Fields!Total.Value). Rename the Textbox something unique, such as Denominator.
Hide the row.
For your percentage formula in the details row, use something like:
=Sum(Fields!Total.Value) / ReportItems!Denominator.Value
