How to use the NVL function in decoding?

Hi all

SELECT Decode (Sign (sum (nvl (7), 0)-nvl (sum (5), 0)), - 1, 0, (sum (nvl (7), 0)-nvl (sum (5), 0)) QTY)

of the double

Thank you

You should not do that...

Greatest (NVL (Sum (Quantity), 0)-NVL (SUM (quantity_received), 0), 0) AS qty_arrival

will do the same

How to use the NVL function to a parameter with comma delimited values

Gurus,
It is confusing to me. I am trying to use the NVL function, but the setting that I'm passing in my cursor contains multiple values with commas. The NVL function is confused when analyzing the values.
'Where' cursor clause...
and nvl (sn.c_attribute1,'x@#$%') in nvl (p_desig,'x@#$%'( )
translated parameter values...
and nvl (sn.c_attribute1,'x@#$%') in nvl ('SPRT''GOOD' 'BAD' 'x@#$%') -NVL does not parse the value correctly
Any idea on how to get NVL recognize 'x@#$%' , if p_desig is null?

How to use the @accum function in the calculation script

Dear all.
I'm new in essbase - calculation script so don't know how to use the @accum function.
I want the aggregation value of child to parent
Hierarchy
Product
100 > Storage Dimensions marked as stored (marked as intentionally as I want to calculate the value using the calculation script)
100. 10 (+)
100-20 (+)
100-30 (+)
I'm trying calculation Script
100 = @Accum (@children("100"), jan: Feb);
It works when I use below
100 = @Accum("100-10",Jan:Feb);
Error:-number of Dimensions [1] does not match number of gen/lev [3] office [@Dim]
Don't know how I can roll up to an aggregate value of all the members of the child to the parent.

you do this more difficult it must be. If you want to accumulate up to 100 then you could just make your calc

'100 '.

but that would be only 100, to make the OU any dimension would

AGG (Product);

Or better yet

AGG (Product, Market);

How to use the goto function?

How to use the goto function in indesign javascript?
my script begins by chekcing if the input files are present or not... If one of the input files is not present, I want the n function put an end to the operation in the display of the message tht file exists... I was wondering to use goto for tht... then how to use it? or is there an alternative to that?

GoTo is generally frowned upon by the programmers.

The only legitimate use of goto is when you need to escape from a nested loop.

If you need to jump into a routine, use break or simply in return from the current function.

The model currently used by the SDK looks like this:
```
do
{
     if(condition1 == false)
          break;
     if(condition2 == false)
          break;
     if(condition3 == false)
          break;
     doSomethingReallyCool();
}while(false);
```
'break' the jumps at the end of the do / while loop that always comes out when you reach the end of it (while (false))

How to use the TRUNC function with dates in the expression builder in OBIEE.
Hello
How to use the TRUNC function with dates in the expression builder in OBIEE.
TRUNC (SYSDATE, 'MM') returns 1 July 2010"where sysdate is July 15, 2010 ' in SQL. I need to use the same in the expression builder in the logical layer mdb column.

Thanks in advance
Use it instead:
TIMESTAMPADD (SQL_TSI_DAY, (DAYOFMONTH (CURRENT_DATE) *-1) + 1, CURRENT_DATE)

Do I need to use the NVL function for this request?
I seem to have some problems using the NVL function on a date. I'm trying to create a query pulls back just a date a file was sent between the sysdate and the date_sent more a minute. Here is the code I use...

Oracle: 10.2 G
```
SELECT date_sent as date_sent
INTO    iDateSent
FROM    tableX
WHERE  file_id= 9999
AND    date_sent BETWEEN sysdate AND date_sent + 1/1440; 
```
Currently Output (null):
```
DATE_SENT
```
Desired output when date_sent is null:
```
DATE_SENT
0:0:000 0:00:00
```
Note:
date_sent column is in a normal date - same format as sysdate format.

The problem I encounter is when date_sent is null, the stored procedure, I built crashes because date_sent returns a null and a null value cannot be stored in the variable 'iDateSent '. I was thinking about using the NVL function here to resolve, however, I'm not entirely sure who will work with the above query. Any thoughts?

Hello

you said: "desired output when date_sent is null: date_sent: 0".
It is not possible to have a date of 'zero '.

"and a null value cannot be stored in the variable 'iDateSent'. '.

I do not think: If this variable is declared normally (without any not null not constrained to this topic) so that it can contain a null value. (it's 99% of the time in PL/SQL).

I think it's that your SQL retrieves no rows, to manage what you should put an exception handler:
```
begin
SELECT date_sent as date_sent
INTO    iDateSent
FROM    tableX
WHERE  file_id= 9999
AND    date_sent BETWEEN sysdate AND date_sent + 1/1440;
exception when NO_DATA_FOUND then
 iDateSent:=null;
end;
```
So what you can do if you don't want the date empty a nvl:
```
return(nvl(iDateSent,sysdate));  -- or another date ...
```

How to use the add_months() function in a mapping?

Hello
I have a variable in ODI with a date and I need to add another variable to add 'x' months...
How can do that?
Thank you

If you say you have variable1 organise a date for example 01/01/2015 and variable 2 holding a certain number of months for example 7?

If so in your mapping expression simply use the date functions available to your database technology (step/target) and replace the variable in the function

that is for Oracle your mapping would be ADD_MONTHS (#Variable1,Variable2of #)

How to use the Substring function with Case statement.
Hi all

I have a requirement where I have to use the substring function on the ground for the report criteria.
FOR EXAMPLE
I branch domain name where I have all the information of the branch names, now some of the branch names are too large with an extension after the name.
now I want substing it, but the length of characters varies for each branch.
so is it possible where we use a box where we can define if the character of name plug exceed a value then he substing with this length.
Try something like this:

LENGTH WHEN CARTER (tablename. Branch_Name) > n THEN SUBSTRING (...) Of ANOTHER tablename. Branch_Name END

where n is the number of characters that you want to start the break.

Decode the statement using the nvl function
I inherited the code uses a decode and nvl. I'm not sure the purpose of him and wants confirmation that it is logical and an error. The situation can be re-created by implementing the following.

CREATE TABLE XX_TEST
(IDENTIFICATION NUMBER,
DOMAIN VARCHAR2 (255)
)

INSERT INTO XX_TEST (ID, FIELD) VALUES (1, 'Yes')
INSERT INTO XX_TEST (ID, FIELD) VALUES (2, 'No')
INSERT INTO XX_TEST (ID, FIELD) VALUES (3, NULL)

Commit

SELECT ID,
FIELD,
DECODE (on the GROUND, the 'yes', ' Yes result this ", NVL (FIELD, 'No'),"no results don't do this","catch all result do this")
OF XX_TEST

I'm not sure of the NVL (FIELD, 'No') I think that the creator may have thought this would draw the NULL values, but it is not.
Null is not converted into no. and plunges into the place the Tote. Can anyone help with an explanation of how oracle is interpretting the select statement. Any ideas on why NVL would be used like that? Seems a mistake?
decode compares them the first FIELD against NVL (FIELD, 'No').
If the FIELD is null estimated them VSN none which is not null, then...
just to make an entry for the null value and one for the 'no' with the same result.
However, I prefer case statement in this case.
```
SELECT ID,
FIELD,
case
when FIELD ='Yes' then 'Yes Result do this'
when FIELD is null or FIELD = 'No' THen 'No result do this'
else 'catch all result do this'
end
FROM XX_TEST
```
As more readable.

How to use the node function call library for a function in the dll with the data SUB type

Hi all

I would ask for your kind help

I am facing a problem with the call library node.

I have a C++ (stdcall) function, which has Sub as data type

XXXX error code (hwnd, lid, getValue, * Sub data1, * Sub data2)

data1 and data2 types are constantly changing based on the value of 'getValue '.

Mainly I can use the call library node several times and adapt each node according to the types of data data1, data2 and extract the values and use in the code. Here is no question. Real question is:

My question:

How can I use a node of library time call and make a case according to the 'getvalue', who will control the data1, data2 data type. Here I really seeking solutions.

My tests:

I used varaints as entry to the libray call node of the data1, data2 and selected parameters in the call libraby node as "Adapt to type. Here labview just crashed.

I appreciate your suggestions to feedbackand.

Thank you

Karine

You must allocate enough space for data1 and data2, and then pass a pointer to this space. An easy way to do this is the function to initialize table. Set the U8 type and size for the number of bytes required. Pass this array to the function as a pointer of table data.

After the function call returns, you need to extract the data in the table. You can do it manually, but a simple approach is to use the array of bytes to a string. Then, in a housing structure, use Unflatten chain to convert the string to the correct data type. This method also converts the "endianness" which will be probably necessary; Be sure to only set all entries for unflatten correctly.

How to use the ratio_to_report function
Hello
I have a problem using ratio_to_report to create the following report.
I have a table MYTABLE with three columns A, B and C.
A, B AND C
1 150 positive
1 130 positive
1 110 negative
1 150 negative
1 110 negative
2 150 negative
2 110 positive
2 110 negative
...
I want to get is a report where I have a column reports the percentage of negative situations of a certain group of B value by a column.
In my case, for example, I would like to provide you a report where the new PERCENTAGE column will contain the negative of the value 150 b within Group 1 rate, then the negative of the rate of 150 in Group 2 and so on for each value of B, which is such a report:
A PERCENTAGE_NEGATIVE B
1 150 15%
1 130 30%
1 110 0%
2 150 35%
2 110 25%
Pay attention that in the report above, I have not calculated the right percentage value
Thanks in advance.
Hello

Simper is not not to use RATIO_TO_REPORT for that:
```
SELECT       a, b
,       COUNT ( CASE
               WHEN  c = 'negative'
               THEN  1
            END
          ) * 100 / COUNT (*)     AS percentage_negative
FROM       mytable
GROUP BY  a, b
ORDER BY  a, b
;
```
You use RATIO_TO_REPORT, you could do a subquery to calculate RATIO_TO_REPORT for all values of c and then filter all except the "negative in the main query.

Why? With only 8 rows of sample data, would be easy enough to manually calculate the correct results? It would be much more useful to people who want to help you.
