I am bit new to MYSQL. I want to sort Dataset(SQL output) results on two column depending on user selection.
In my table, I have following two column related to Processing Charges:
1: Proc_Percentage - Float
2: Proc_Fees. - Float
Each row will have value for EITHER of one Column.
For example 1% or 2345 $.
Another example 1.5% or 678 $ like that.
Sample Data:
Row 1: 1% NULL
Row 2: NULL 2345
Row 3: 1.5% NULL
Row 4: NULL 678
Row 5: 0.5% NULL
Row 6: NULL 1234
*Please note that None of above row contain vlaue for both the column
On the front end, I have a DROP DOWN where user can sort the results based on his like such as sort by Proc Percentage or Proc Fees.
However, Results have to displayed under one column only with title : "Proc Charges".
Thus, if user selects Sort by Proc_Percentages, I would like to show results in following order.
Sample Results when Sort if based on Percentage
Proc Charges
1: 0.5%
2: 1.0%
3: 1.5%*
4: 2345
5: 1234
6: 678
Here order of only 1 to 3 matters (PERCENTAGE Sorting). Row 4 to 6 can come in any order.
On the other end, if user selects Sort by Proc_Fees, I would like to show results in following order.
Sample Results when Sort if based on Percentage
Proc Charges
1: 678
2: 1234
3: 2345*
4: 1%
5: 1.5%
6: 0.5%
Here order of only 1 to 3 matters (FEES Sorting). Row 4 to 6 can come in any order.
Can someone explaing me how can I achieve this? I tried to use order by perd desc, fees asc but did not work.
Thanks
Something like this
For Proc_Percentage
SELECT * FROM
TableName
Order By CASE WHEN LOCATE('%',ColumnName)>0 Then 1 Else 999999;
For Proc_Fees
SELECT * FROM
TableName
Order By CASE WHEN LOCATE('%',ColumnName)>0 Then 999999 Else 1;
try this
order by ifnull($selected_column, 999999) asc

I have a requirement related as below
1-If there is employee record then count the number of rows
a-if there are four rows then follow the layout 1,
and populate the column1 and column 2 with values in report and ltrimrtrim
b- if there are three rows, then follow the layout 2,
and hardcode the column 1 and column 2 with NULL
Otherwise, look for the employee record.
Couldn't get the logic, I used the router with as if column 1 and two null the send to layout two else 1. But the requirement is different.
router transformation, if null, layout one else 2
Step 1 - Use SRT>AGG>JNR to calculate count. create new column as count_all and set to COUNT(*). Please group by proper key columns.
Step 2 - Use RTR next to split data based on your condition.
group 1- count_all =4 then follow the layout 1 and...
group 2- count_all =3 then follow the layout 2 and...
group 3 - if count <3 then do employee record.
I have the following situation:
column 1 column 2 column 3
A 1 1
A 1 2
B 3 4
B 3 5
I need to color my letters when the value in column 2 never occurs in column 3. But I need to color all my letters. Does anyone know how to write a case statement for this?
So I'll explain my example: I dont't need to color the letter A because there is a match between column 2 and 3 and the first row.
I do need to color my B's because there is never a match between columns 2 and 3.
I already tried this:
count(distinct(case when "Column 2" != "Column 3" then 1 else 0 end))
but this gives a result for each row and I need a result for the total package.
Thanks!
You can approach this as following:
Create a logical column on your analysis that does a case statement that returns 1 or 0 depending if the values of column2 and column3 are the same (pretty much like the case-when that you provided on your answer but without the count distinct).
Wrap that case statement with a MAX grouped by your column1. This will give you either a consistent 1 or 0 across all your different values of column1. You can use this value for your conditional formatting. The key here is to use the aggregated function with the group by.
You have here some oracle documentation on how to use the logical SQL group by.
Hope that helps! Good luck!
I have a table in oracle database which may contain amounts >=$10M or <=$-10B.
99999999.99 chunks and also include remainder.
If the value is less than or equal to $-10B, I need to break into one or more 999999999.99 chunks and also include remainder.
Your question is somewhat unreadable, but unless you did not provide examples here is something for start, which may help you or someone with similar problem.
Let's say you have this data and you want to divide amounts into chunks not greater than 999:
id amount
-- ------
1 1500
2 800
3 2500
This query:
select id, amount,
case when level=floor(amount/999)+1 then mod(amount, 999) else 999 end chunk
from data
connect by level<=floor(amount/999)+1
and prior id = id and prior dbms_random.value is not null
...divides amounts, last row contains remainder. Output is:
ID AMOUNT CHUNK
------ ---------- ----------
1 1500 999
1 1500 501
2 800 800
3 2500 999
3 2500 999
3 2500 502
SQLFiddle demo
Edit: full query according to additional explanations:
select id, amount,
case
when amount>=0 and level=floor(amount/9999999.99)+1 then mod(amount, 9999999.99)
when amount>=0 then 9999999.99
when level=floor(-amount/999999999.99)+1 then -mod(-amount, 999999999.99)
else -999999999.99
end chunk
from data
connect by ((amount>=0 and level<=floor(amount/9999999.99)+1)
or (amount<0 and level<=floor(-amount/999999999.99)+1))
and prior id = id and prior dbms_random.value is not null

Please adjust numbers for positive and negative borders (9999999.99 and 999999999.99) according to your needs.
There are more possible solutions (recursive CTE query, PLSQL procedure, maybe others), this hierarchical query is one of them.
I'm dealing whit this for a couple of hours and I can't find the way to get the answer.
I've a table with a maximun of 4 records for a product (let's call it that way) for a diferent period (column name with a number). I'm trying to return the ones that DO NOT has a particular type of CONSUMPTION_TYPE_ID. But it doesn't work.
I'll explain it simple. I've a table with these fields (there are more, but these one are just fine)
product_id - CONSUMPTION_TYPE_ID - consumption_period
123 103 1
123 104 1
123 107 1
123 108 1
I need to return the ones that don't has one particular type of consumption, let's say that the type 107 is missing (the row doesn't exists), the select query should show the other 3 or any present. I don't mind doing the same select 4 times, I could also try to do a cursor for it and use loop to check every one. The point is, that the type of query with "not in" or "not exists" doesn't work. It gives me a result like the one given below, but when I query the "consumption_period" it shows me the missing "CONSUMPTION_TYPE_ID" and that's because the "not in" clause it's only hidding the results.
this is what I need.
select * from t1 where CONSUMPTION_TYPE_ID != 108;
product_id - CONSUMPTION_TYPE_ID - consumption_period
123 103 1
123 104 1
123 107 1
I hope you can help me with this. I'm stucked, it maybe simple, but I'm having one of those stucked times. Thanks in advance for any help
You probably should've posted that NOT EXISTS query that doesn't work, because that is the right way to do this.
If I got your requirements right: all products that do not have a record for a specific consumption_type_id.
SELECT DISTINCT product_id
FROM t1 t
WHERE NOT EXISTS
(SELECT 1 FROM t1
WHERE t.product_id = product_id
AND Consumption_Type_ID = ?)
The obvious answer here is to search for CONSUMPTION_TYPE_ID = 108 and have the surrounding code check for a lack of rows, rather than the existence of rows.
If you really need a row return for each consumption_type_id that's not in this table, then you should probably be selecting from the lookup table for consumption_type_id:
select *
from consumption_type ct
where not exists (select *
from t1
where t1.consumption_type_id = ct.consumption_type_id)
and ct.consumption_type_id = 108
This is a very complicated situation for me and I was wondering if someone can help me with it:

In my table every value in the SQLCalculatedPmu column or desiredValue Column is calculated based on the preceding value.
As you can see, I have calculated the SQLcalculatedPMU column based on the round on 3 decimals. The case is that on each line radiation, the client want to start the next calculation based on 2 decimals instead of 3(represented in the desired values column). Next values will be recalculated. For example line 6 will change as the value in line 5 is now on 2 decimals. I could handle this if there where one single radiation but in my case I have a lot of Radiations and in this case they will change all based on the calculation of the two decimals.
In summary, Here are the steps:
1 - round the value of the preceding row of a raditaiton and put it in the radiation row.
2 - calculate all next insertion rows.
3 - when we reach another radiation we redo steps 1 and 2 and so on
I m using an oracle DB and I m the owner so I can make procedures, insert, update, select.
But I m not familiar with procedures or loops.
For information, this is the formula for SQLCalculatedPmu uses two additional culmns price and number and this is calculated every line cumulativelly for each investor:
(price * number)+(cumulative (price*number) of the preceeding lines)
I tried something like this :
update PMUTemp
set SQLCalculatedPmu =
case when Type = 'Insertion' then
(number*price)+lag(SQLCalculatedPmu ,1) over (partition by investor
order by Record_no)/
(number+lag(solde,1) over (partition by investor order by Record_no))
else
TRUNC(lag(SQLCalculatedPmu,1) over partition by invetor order by Record_no))
end;
but I gave me this error (I think it's because I m looking at the preceiding line that itself is modified during the SQL statement) :
ORA-30486 : window function are allowed only in the SELECT list of a query.
I was wondering if creating a procedure that will be called as many time as the number of radiations would do the job but I m really not good in procedures
Any help
Regards,
just to make my need simpler, all I want is to have the DesiredValues column starting from the SQLCalculatedPmu column. Steps are
1 - on a radiation the value become = trunc(preceding value,2)
2 - calculate all next insertion rows this way : (price * number)+(cumulative (price*number) of the preceeding lines). As the radiation value have changed then I need to recalculate next lines based on it
3 - when we reach another radiation we redo steps 1 and 2 and so on
Kindest regards
You should not need a procedure here -- a SQL update of the Radiation rows in the table would do this quicker and more reliably.
Something like ..
update my_table t1
set (column_1, column_2) =
(select round(column_1,2), round(column_2,2)
from my_table t2
where t2.type = 'Insertion' and
t2.record_no = (select max(t3.record_no)
from my_table t3
where t3.type = 'Insertion' and
t3.record_no < t1.record_no ))
where t1.type = 'Radiation'
