I have a Table box that contains a single field "Numb":
Sample Data:
Numb
A1001
A1002
A1003
A1004
A1005
A1006
A1007
A1008
A1009
A1010
A1011
A1012
A1014
A1015
A1016
A1017
A1018
A1020
I want to have a second table box (or straight table whatever works) with an expression that shows the row before and the row after any missing rows that don't run on in green and then the missing row in red.
Expected Output:
CheckNumb
A1012
A1013
A1014
A1018
A1019
A1020
If you only have numbers in your data you can skip this part.
In the load script add the following to remove the letter:
purgechar(Numb,'A') AS NumbOnly
Then adding a straight table with a dimension of:
NumbOnly
Create an expression using the ABOVE function:
=IF(NumbOnly-Above(NumbOnly) = 1 ,'Match','Check')
This will check if the row above is more than 1 apart.

I have a stream with a column with a variable number of semicolon deliminated values with a layout like
activities ticket_id
1;2;3 1
4;5 2
6; 3
7;8;9;10 4
. How can I get a new row for ever activity, like this
activity_id ticket_id
1 1
2 1
3 1
4 2
and so on?
In case I formatted this question wrong, here's an image
Simply use the "Split field to rows" step, use the Activities column as the field to split and ";" as the Delimeter.
Remenber that when you have a single value AND the delimeter, the step will output an additional row with an empty string. In this scenario the step will auto adjust the ticket_id column to repeat the values.
This solution in the screenshot below worked too
New user, so apologies in advance for bad formatting.
Essentially what I'm trying to do is be able to populate the staff_hours column where it equals NULL with the one value that IS NOT NULL. As you can see from the screenshot, there will only be one person who staffs an open cl_hole_staffing_no and as a result will have a start_dt (with time) and end_dt (with time) along with staff_hours. 16 people were offered a shift, and the person in row 15 accepted it is what is going on here.
The ideal output would be the staff_hours column is populated with the amount of time of the one person who ended up taking the open job, so 24.00 in this example. How can I write a formula to do this? I was thinking something like an array function in Excel, but am not sure how to do that in SQL.
Your explanation is a bit confusing about what you are really trying to achieve. However I think that what you really want is just to populate the staff_hours column, which can be achieved with the following:
UPDATE
your_table_name
SET
staff_hours = 24
WHERE
staff_hours is NULL;
EDIT
I get it now. You want to operate with the two dates and extract the amount of hours between them. Since you are in sql-server you can actually define a Computed Column in which you can use the values from other columns to compute the value you want.
You will need to create your table again. (The example below contains only the necessary attributes for it to work)
CREATE TABLE your_table_name
( id INT IDENTITY (1,1) NOT NULL
, staff_start_dt DATETIME
, staff_end_dt DATETIME
, staff_hours AS DATEDIFF(hh, staff_start_dt , staff_end_dt)
);
Now every time you insert a record on the table with both staff_start_dt and staff_end_dt, the column staff_hours will automatically compute the number of hours between the two dates.

Code (vb):
A B C
1 10 X X
2 11 A Y
3 12 Y Z
4 13 B
5 14 B
6 15 Z
[/pre]
Assuming that the rows in Col A is Named "datarange"
And your criteria is in C1:C3
The following formula will return an array {10,12,15}
=SMALL(COUNTIF(C1:C3,B1:B6)*datarange, ROW(INDEX(A:A,SUMPRODUCT(--(COUNTIF(C1:C3,B1:B6)=0))+1):INDEX(A:A,ROWS(datarange))))
COUNTIF(C1:C3,B1:B6)*datarange returns {10;0;12;0;0;15}
The segment ROW(INDEX(....):INDEX(...)) returns {4;5;6}, indicating the number of non-zero values.
The SMALL() function then returns the 4th smallest, 5th smallest and 6th smallest values.
One disadvantage with this approach is that you get a sorted sub-list. Perhaps that would work for you.
I have a column that stores 2 values. Example below:
| Column 1 |
|some title1 =ExtractThis ; Source Title12 = ExtractThis2|
I want to remove 'ExtractThis' into one column and 'ExtractThis2' into another column. I've tried using a substring but it doesn't work as the data in column 1 is variable and therefore it doesn't always carve out my intended values. SQL below:
SELECT substring(d.Column1,13,24) FROM dbo.Table d
This returns 'Extract This' but for other columns it either takes too much or too little. Is there a function or combination of functions that will allow me to split consistently on the character? This is consistent in my column unlike my length count.
select substring(col1,CHARINDEX('=',col1)+1,CHARINDEX (';',col1)-CHARINDEX ('=',col1)-1) Val1,
substring(col1,CHARINDEX('=',col1,CHARINDEX (';',col1))+1,LEN(col1)) Val2
from #data
there is duplicate calculation that can be reduced from 5 to 3 to each line.
but I want to believe this simple optimization done by SQL SERVER.
I have a powerpivot table that contains 2 columns:
Column 1 contains strings.
Column 2 contains comma delimited strings.
I would like to be able to display all the rows from column 1 when rows from column 2 contains the selection from a filter or slicer. For example:
String Values
ABCD A,A,B
EFGH A,C
if A is selected I would display both rows, if B is selected I would display only row 1...etc.
I know I can split the records - but this is not practical for me - the above is only the top of the iceberg. VBA is out of the question since this will published in SharePoint. Anybody has an idea on how I could do that ? Thanks.
I found the solution in a blog from Javier Guillem:
http://javierguillen.wordpress.com/2012/02/10/simulating-an-approximate-match-vlookup-in-powerpivot/
If in my example the name of the table is "facts", I create a second unlinked table called dimRef that I populate with all possible values that I am interested to match: A,B,C,D...etc.
Then I define the measure M as:
M:=If ( Hasonevalue(facts[Values] ),
Calculate (
LASTNONBLANK (dimRef[String], 1 ),
Filter ( dimRef, SEARCH(dimRef[String],Values(facts[String]),1,0) > 0 )
)
)
I can then use the string column of the facts table and the measure in a pivot table and use dimRef as a selector. If filters the row as per the selection.
One small detail: the measure is not available in PowerView...Anybody knows why ?
I have one table that stores a range of integers in a field, sort of like a print range, (e.g. "1-2,4-7,9-11"). This field could also contain a single number.
My goal is to join this table to a second one that has discrete values instead of ranges.
So if table one contains
1-2,5
9-15
7
And table two contains
1
2
3
4
5
6
7
8
9
10
The result of the join would be
1-2,5 1
1-2,5 2
1-2,5 5
7 7
9-15 9
9-15 10
Working in SQL Server 2008 R2.
Use a string split function of your choice to split on comma. Figure out the min/max values and join using between.
SQL Fiddle
MS SQL Server 2012 Schema Setup:
create table T1(Col1 varchar(10))
create table T2(Col2 int)
insert into T1 values
('1-2,5'),
('9-15'),
('7')
insert into T2 values (1),(2),(3),(4),(5),(6),(7),(8),(9),(10)
Query 1:
select T1.Col1,
T2.Col2
from T2
inner join (
select T1.Col1,
cast(left(S.Item, charindex('-', S.Item+'-')-1) as int) MinValue,
cast(stuff(S.Item, 1, charindex('-', S.Item), '') as int) MaxValue
from T1
cross apply dbo.Split(T1.Col1, ',') as S
) as T1
on T2.Col2 between T1.MinValue and T1.MaxValue
Results:
| COL1 | COL2 |
----------------
| 1-2,5 | 1 |
| 1-2,5 | 2 |
| 1-2,5 | 5 |
| 9-15 | 9 |
| 9-15 | 10 |
| 7 | 7 |
Like everybody has said, this is a pain to do natively in SQL Server. If you must then I think this is the proper approach.
First determine your rules for parsing the string, then break down the process into well-defined and understood problems.
Based on your example, I think this is the process:
Separate comma separated values in the string into rows
If the data does not contain a dash, then it's finished (it's a standalone value)
If it does contain a dash, parse the left and right sides of the dash
Given the left and right sides (the range) determine all the values between them into rows
I would create a temp table to populate the parsing results into which needs two columns:
SourceRowID INT, ContainedValue INT
and another to use for intermediate processing:
SourceRowID INT, ContainedValues VARCHAR
Parse your comma-separated values into their own rows using a CTE like this Step 1 is now a well-defined and understood problem to solve:
Turning a Comma Separated string into individual rows
So your result from the source
'1-2,5'
will be:
'1-2'
'5'
From there, SELECT from that processing table where the field does not contain a dash. Step 2 is now a well-defined and understood problem to solve These are standalone numbers and can go straight into the results temp table. The results table should also get the ID reference to the original row.
Next would be to parse the values to the left and right of the dash using CHARINDEX to locate it, then the appropriate LEFT and RIGHT functions as needed. This will give you the starting and ending value.
Here is a relevant question for accomplishing this step 3 is now a well-defined and understood problem to solve:
T-SQL substring - separating first and last name
Now you have separated the starting and ending values. Use another function which can explode this range. Step 4 is now a well-defined and understood problem to solve:
SQL: create sequential list of numbers from various starting points
SELECT all N between #min and #max
What is the best way to create and populate a numbers table?
and, also, insert it into the temp table.
Now what you should have is a temp table with every value in the exploded range.
Simply JOIN that to the other table on the values now, then to your source table on the ID reference and you're there.
My suggestion is to add one more field and many more records to your ranges table. Specifically, the primary key would be the integer and the other field would be the range. Records would look like this:
number range
1 1-2,5
2 1-2,5
3 na
4 na
5 1-2,5
etc
Having said that, this is still rather limiting because a number can only have one range. If you want to be thorough, set up a many to many relationship between numbers and ranges.
As far as I can tell you best option is something like below:
Create a table value function that accepts your ranges an converts them to a collection of ints. So 1-3,5 would return:
1
2
3
5
Then use these results to join to other tables. I don't have an exact function to do this at hand, but this one seems like an excellent start.
