Reverse MS-Access Format Function - sql

I have a field within an Access 2007 database which contains either a 0 or a 1.
When displaying a view, I need to format the field as Yes/No.
My issue is that I can't use FORMAT(Field,"Yes/No") as the 1 and 0 are the wrong way round i.e.:
0 = No 1 = Yes is how the format function works.
1 = No 0 = Yes is how my data is formatted.
Is there anyway to reserve or manipulate the FORMAT function in a way that when a query is run, the query will display my Yes/No the correct way round?

FORMAT(ABS(Field-1), "Yes/No")
This works because ABS(1-1) = 0 and ABS(0-1) = 1. In other words your 0 -> 1 and 1 -> 0, so it changes the number to have the "right" value (as far as MS-Access is concerned) before using the format function.

Lookupset with duplicate records SUM not working SSRS 2008

I have the below data in a dataset called Questions and all IDs in another dataset called Dataset1
ID Answer
1 Yes
2 Yes
2 No
2 Yes
3 No
My expected output should be as below
ID Yes No
1 1 0
2 2 1
3 0 1
I am trying to match the ids from Dataset1 and get the Answer from Questions dataset.
If I just use Lookup, it is just checking the first match and ignoring the second record. For eg, in the above data, for ID-2, it is checking the first record with id 2 and counting 'Yes' and ignoring the other 'No' and 'Yes'
=Sum(iif(Lookup(Fields!ID.Value, Fields!ID.Value, Fields!answer.Value, "Questions") = "Yes", 1, 0))
I want to count all Yes and No like shown in the expected output above
I have tried using Lookupset but I couldn't get it working. Is there any easier way without using custom code. If custom code is necessary, could you please advise on how to achieve this.
Thank you in advance.
Why do you need a second dataset?
Have a matrix on the questions dataset, row grouped by ID then use a sum in each column as follows:
=SUM(IIF(Fields!answer.Value="Yes",1,0))
=SUM(IIF(Fields!answer.Value="No",1,0))
You can count the output from a lookupset by using the following custom code:
Function CountAnswers(ByVal AnswerArray As Object(), Answer As string) As Object
If AnswerArray Is Nothing Then Return cint(0)
If Answer Is Nothing Then Return "Nothing"
Dim TotalCount As Decimal = New Decimal()
Dim AnswerPosition As Decimal = New Decimal()
TotalCount = 0
For AnswerPosition = 0 to AnswerArray.GetUpperBound(0)
TotalCount = Switch(IsNothing(AnswerArray(AnswerPosition)),TotalCount, cstr(AnswerArray(AnswerPosition))=Answer,TotalCount + 1, TRUE,TotalCount)
Next
return TotalCount
End Function
Then enter the following under "Yes" and "No" on a matrix on Dataset1:
Code.CountAnswers(Lookupset(Fields!ID.Value, Fields!ID.Value, Fields!answer.Value,"Questions"),"Yes")
Code.CountAnswers(Lookupset(Fields!ID.Value, Fields!ID.Value, Fields!answer.Value,"Questions"),"No")

How to find every combination of a binary 16 digit number

I have 16 different options in my program and i have a 16 character variable which is filled with 1's or 0's depending on the options that are selected (0000000000000000 means nothing is selected, 0010101010000101 means options 3,5,7,9,14 and 16 are selected, 1111111111111111 means everything is selected.)
When i run my program, the code looks (using an if statement) for a 1 in the designated character of the 16 digit number and if there is one there then it runs the code for that option, otherwise it skips it..
e.g option 3 looks too see if the 3rd character (0010000000000000) is a 1 and if it is it runs the code.
Now what i am trying to do is generate a list of every different combination that is possible so I can create an option for it to just loop through and run every possible option:
0000000000000001
0000000000000010
0000000000000011
...
1111111111111100
1111111111111110
1111111111111111
I have tried this but i think it may take a couple of years to run jaja:
Dim binString As String
Dim binNUM As Decimal = "0.0000000000000001"
Do Until binNUM = 0.11111111111111111
binString = binNUM.ToString
If binString.Contains(1) Then
If binString.Contains(2) Or binString.Contains(3) Or binString.Contains(4) Or binString.Contains(5) Or binString.Contains(6) Or binString.Contains(7) Or binString.Contains(8) Or binString.Contains(9) Then
Else
Debug.Print(binNUM)
End If
End If
binNUM = binNUM + 0.0000000000000001
After the code above is complete i would then take the output list and remove any instances of "0." and then any lines which had fewer than 16 chararcters (because the final character would be a 0 and not show) I would add a 0 until there was 16 characters. I know this bit might be stupid but its as far a ive got
Is there a faster way I can I generate a list like this in VB.net?
You should be able to get the list by using Convert.ToString as follows:
Dim sb As New System.Text.StringBuilder
For i As Integer = 0 To 65535
sb.AppendLine(Convert.ToString(i, 2).PadLeft(16, "0"c))
Next
Debug.Print(sb.ToString())
BTW: This should finish in under one second, depending on your system ;-)
Create an enum with FlagAttributes, which allows you to do the key functions you list. Here is an example of setting it up in a small project I am working on:
<FlagsAttribute>
Public Enum MyFlags As Integer
None = 0
One = 1
Two = 2
Three = 4
Four = 8
Five = 16
Recon = 32
Saboteur = 64
Mine = 128
Headquarters = 256
End Enum
e.g.
Dim temp as MyFlags
Dim doesIt as Boolean
temp = MyFlags.One
doesIt = temp.HasFlag(MyFlags.Two)
temp = temp OR MyFlags.Three
'etc.
The real advantage is how it prints out, if you want something other than 0, 1 and is much more human friendly.

Strange numbers in the output from Netcdf in Fortran

I'm fairly new to Fortran and try reading in 3D (80000*100*10) single precision NetCDF data (however I'd just read it 2D like (80000,100,1st)). I would need to convert them into double precision for some further code not shown below.
The .nc-File which I create to check if the reading/writing works does contain only "0" if I use real single precision for all NF90-functions as well as the variable 'values'.
It does contain mostly "0" and several weird numbers which don't seem to relate in a conceivable way to the input data if I use double precision (code shown below). At least I get any output in my nc file this way.
I don't get any compiling errors {nor error codes in 'STATUS' if I check for specific lines after NF90 functions. Update: That was mistaken}. Input_test.nc gets created exactly as expected regarding dimensions, but not regarding the actual values.
My code is:
PROGRAM read
Implicit None
INCLUDE 'netcdf.inc'
INTEGER :: NCID, horstart, verstart, horlen, verlen, horcount, vercount, STATUS, STATUS2
REAL(kind=8), DIMENSION(80000,100) :: values
horstart = 1
verstart = 1
horcount = 80000 !!(tried to use this instead of horlen, doesn't change anything)
vercount = 100 !!(tried to use this instead of verlen, doesn't change)
varname = 'pres'
!! get input data
STATUS = NF90_OPEN('my_valid_path/file.nc', 0, NCID)
STATUS = NF90_INQ_DIMID(NCID, 'ncells', horid)
STATUS = NF90_INQ_DIMID(NCID, 'height', verid)
STATUS = NF90_INQ_DIMLEN(NCID,horid,horlen)
STATUS = NF90_INQ_DIMLEN(NCID,verid,verlen)
STATUS = NF90_INQ_VARID(NCID,varname,varid)
STATUS = NF90_GET_VARA_DOUBLE(NCID,varid,[horstart,verstart,1],[horlen,verlen,1],values)
STATUS = NF90_CLOSE(NCID)
STATUS = NF90_CREATE ('some_path/input_test.nc', 0, ncid);
STATUS = NF90_DEF_DIM (ncid, 'hor',horcount, dimhor)
STATUS = NF90_DEF_DIM (ncid, 'ver',vercount, dimver)
STATUS = NF90_DEF_DIM (ncid, '1d',1, dimcode)
STATUS = NF90_DEF_VAR(ncid,'pres',NF90_DOUBLE,2,[dimhor,dimver],pres_id)
STATUS = NF90_DEF_VAR(ncid,'status',NF90_INT,1,dimcode,stat_id)
STATUS = NF90_ENDDEF(ncid)
STATUS = NF90_PUT_VARA_DOUBLE(ncid,pres_id,[horstart,verstart],[horcount,vercount],values)
STATUS = NF90_PUT_VARA_INT(ncid,stat_id,1,1,STATUS2)
STATUS = NF90_CLOSE(ncid)
The nc file I read from doesn't contain any zeroes, not even in the 3rd dimension. The Output file however does contain a lot zeroes, it is not empty though.
Example input: 0,095213220 0,099325478 0,10358732 0,10800611 0,11259078 0,11734842 0,12228279 0,12740466 0,13271827 0,13822863 0,14394356
Example output: 0 0 0 0 0 0,000493943283800036 0,000594558776356280 0,000234268474741839 2,88491937681101e-05 2,09666131608306e-16 7,30948746534081e-20
I'm probably doing something stupid, but I went temporarily out of ideas what to check for.
UPDATE: Thoroughly checking the error codes saved in STATUS did give a non-zero match at NF90_GET_VARA_DOUBLE/(also REAL). Getting back to this tomorrow.
With error handler I came to the conclusion that the above code works. The errors eventually came from a spelling mistake of the variables I tried to read from.

Octave keyboard input function to filter concatenated string and integer?

if we write 12wkd3, how to choose/filter 123 as integer in octave?
example in octave:
A = input("A?\n")
A?
12wkd3
A = 123
while 12wkd3 is user keyboard input and A = 123 is the expected answer.
assuming that the general form you're looking for is taking an arbitrary string from the user input, removing anything non-numeric, and storing the result it as an integer:
A = input("A? /n",'s');
A = int32(str2num(A(isdigit(A))));
example output:
A?
324bhtk.p89u34
A = 3248934
to clarify what's written above:
in the input statement, the 's' argument causes the answer to get stored as a string, otherwise it's evaluated by Octave first. most inputs would produce errors, others may be interpreted as functions or variables.
isdigit(A) produces a logical array of values for A with a 1 for any character that is a 0-9 number, and 0 otherwise.
isdigit('a1 3 b.') = [0 1 0 1 0 0 0]
A(isdigit(A)) will produce a substring from A using only those values corresponding to a 1 in the logical array above.
A(isdigit(A)) = 13
that still returns a string, so you need to convert it into a number using str2num(). that, however, outputs a double precision number. so finally to get it to be an integer you can use int32()

Using CONTAINS with variables sql

Ok so I am trying to reference one variable with another in SQL.
X= a,b,c,d (x is a string variable with a list of things in it)
Y= b ( Y is a string variable that may or may not have a vaue that appears in X)
I tried this:
Case when Y in (X) then 1 else 0 end as aa
But it doesnt work since it looks for exact matches between X and Y
also tried this:
where contains(X,#Y)
but i cant create Y globally since it is a variable that changes in each row of the table.( x also changes)
A solution in SAS would also be useful.
Thanks
Maybe like will help
select
*
from
t
where
X like ('%'+Y+'%')
or
select
case when (X like ('%'+Y+'%')) then 1 else 0 end
from
t
SQLFiddle example
In SAS I would use the INDEX function, either in a data step or proc sql. This returns the position within the string in which it finds the character(s), or zero if there is no match. Therefore a test if the value returned is greater than zero will result in a binary 1:0 output. You need to use the compress function with the variable containing the search characters as SAS pads the value with blanks.
Data step solution :
aa=index(x,compress(y))>0;
Proc Sql solution :
index(x,compress(y))>0 as aa
