FileMaker - How to have distinct values listed on-screen? - group-by

I would like to have the distinct values of a repeating field listed in another field (in browse mode). The case is as follows:
I have a field that contains country names. The country names in this field may repeat themselves, thus when using the "List" function I get something like "France, France, France, Germany, Germany, Hungary".
How can I create a field that lists all the values from my country field, but has it grouped as "France, Germany, Hungary"?
In the case I could directly use a SQL query to interfere with the FileMaker databse I would use the GROUP BY statement.

To make a summary of all the values across every record, do as follows:
Make a new value list labeled 'Countries' (File Menu > Manage > Value Lists)
Make the value list 'Use Values From Field' and specify your repeating field
Create a new Calculation field, 'Listed Countries'
Set the calculation to type 'Text' and with the following code:
ValueListItems ( Get(FileName) ; "Countries" )
If you'd like to find the value for only the current record:
Make a new Table Occurrence, 'NewTO' of the same base table and link the two records by a unique index.
Change the 'Countries' value list so that it obtains values from 'NewTO' and your repeating field.
Select 'Only include related values starting from' and select your original Table Occurrence
If you'd like the list to update as the repeating field value changes, make certain that you Do Not Store Calculation Results for the field.

How to select columns using a wildcard search on column names in SPSS Modeler

I am doing time series analyis predicting sales for a large amount of products. After executing the time series node, I get a table containing the original sales data and predicted values with a suffix "$TS-" before the product name. Now I would like to select / filter only those columns containing a "$TS-" in the column name.
There is no easy or straightforward way to do something like this. The simplest way, in my opinion, would be to
Add a 'Filter' node after the time series model nugget
Use the funnel button to "Remove all Fields"
Select to include each of the individual fields that you would like to keep
Make sure that the node is set to Include fields by default
If fields are added to your original data sources or if new fields are derived in the stream, you'll have to go back to this node and remove them, so it's not ideal.
The alternative is to use a stream script to change the inclusion and removal of the fields within a "Filter" node. The script below will search for a "Filter" node with the name given by the variable filterNodeName and search for fields with the prefix given by the variable fieldNamePrefix and keep only the fields that match the designated prefix.
filterNodeName = "TS Fields Only"
fieldNamePrefix = "$TS-"
diagram = modeler.script.diagram()
# Find the 'Filter' node
renameFieldsNode = diagram.findByType('filternode', filterNodeName)
# Get the input data model - the fields that go into the 'Filter' node
fields = renameFieldsNode.getInputDataModel()
# Loop through all of the fields
for field in fields:
fieldName = field.getColumnName()
if fieldName.startswith(fieldNamePrefix):
# If the field name starts with the designated prefix then include the field
renameFieldsNode.setKeyedPropertyValue('include', fieldName, True)
else:
# Otherwise do not include the field
renameFieldsNode.setKeyedPropertyValue('include', fieldName, False)

Using MYSQLI to select rows in which part of a column matches part of an input

I have a database in which one of the columns contains a series of information 'tags' about the row that are stored as a comma-separated list (a string) of dynamic length. I am using mysqli within PHP, and I want to select rows in which any of these items match any of the items in an input string.
For example, there could be a row describing an apple, containing the tags: "tasty, red, fruit, sour, sweet, green." I want this to show up as a result in a query like: "SELECT * FROM table WHERE info tags IN ('blue', 'red', 'yellow')", because it has at least one item ("red") overlapping. Kind of like "array_intersect" in PHP.
I think I could use IN if each row had only one tag, and I could use LIKE if I used only one input tag, but both are of dynamic length. I know I can loop over all the input tags, but I was hoping to put this in a single query. Is that possible? If not, can I use a different structure to store the tags in the database to make this possible (something other than a comma separated string)?
I think the best would be to create tags table (id + label) then separate "table_tags" table which holds table_id and tag_id.
that means using JOINS to get the final result.
another (but lazy) solution would be to prefix and suffix tags with commas so the full column contains something like:
,tasty,red,fruit,sour,sweet,green,
and you can do a LIKE search without being worried about overlapping words (i.e red vs bored) and still get a proper match by using LIKE '%,WORD,%'

Filemaker - Summing a field based on another field

In Filemaker Pro 12, I am trying to write a formula for a calculation field that will sum a field in a related table based on another field in that same related table. The normal Filemaker sum equation would look like this:
Sum (Assets::Asset Quantity)
However, I need to specify that only quantities that are related to a field named Asset Type with a value of "Building" will be used to filter the values in Asset Quantity that will be used in the sum.
There are a couple of ways that you could do this:
A new Calculated field
First, you could add a new Calculation field to your Assets table called, say, Building Quantity, with a Calculated Value of:
If (Asset Type = "Building" ; Asset Quantity ; 0)
And then you can use the sum of this new Building Quantity just like you were using Sum(Assets::Asset Quantity) before.
A new relationship
Second, you could add a new Calculated field to your main table with the value always equal to "Building" and then add a new table occurrence of the Assets table. We'll call it "BuildingAssets" and set the relationship so that your IDs match and also your new "Building" field matches the Asset Type
Summary ID \____________/ BuildingAssets::Summary ID
BuildingText / \ BuildingAssets::Asset Type
Then you will use
Sum (BuildingAssets::Asset Quantity)
instead of Sum (Assets::Asset Quantity) so that you only pull the Building types through.
ExecuteSQL
Finally, FileMaker 12 introduced the ExecuteSQL step. This may be the most elegant way to do the above because it doesn't involve changing any schema. The statement would be somethign like:
SELECT
SUM (Asset Quantity)
FROM
Assets
WHERE
Summary ID = ID AND
Asset Type = Building

ValueList from ExecuteSQL() based query in FMP 12

I'm looking into upgrading our FMP11 developed solution to FMP12. For us, key functionality exists around the ValueList feature to DISPLAY one value (e.g. a description) while RETURNING another value (e.g. a UID), into the selected field.
I would be interested if you have been able to replicate this feature from the ExecuteSQL() function (I can successfully return a single ValueList ... having trouble with the above)
many thanks in advance
Giles
Based on the core functionality of value lists, you can't use the ExecuteSQL() function to calculate the value directly inside of the value list dialog box.
What you would have to do is create a table with a single record and two fields. Then you would use an ExecuteSQL() calculation to populate the first and second fields with data. It would be important to make sure you sort your data inside executeSQL() in the same order in both fields.
So your filemaker calculations would be (assuming the first field is key and the second is name and it's from a table called items, and you are looking for where key > 100)
keylist =
ExecuteSQL (
"SELECT key
FROM items
WHERE key > 100
ORDER BY key ASC"
; "" ; "" )
namelist =
ExecuteSQL (
"SELECT name
FROM items
WHERE key > 100
ORDER BY key ASC"
; "" ; "" )
You would then create a value list that uses keylist as the first field, and namelist as the second field, only displaying values from the second field.
It would be nice to have the functionality to calculate a value list, but as far as I know filemaker always needs to pull values from a source outside of the value list dialog box.

Create a new FileMaker layout showing unique records based on one field and a count for each

I have a table like this:
Application,Program,UsedObject
It can have data like this:
A,P1,ZZ
A,P1,BB
A,P2,CC
B,F1,KK
I'd like to create a layout to show:
Application,# of Programs
A,2
B,1
The point is to count the distinct programs.
For the life of me I can't make this work in FileMaker. I've created a summary field to count programs resetting after each group, but because it doesn't eliminate the duplicate programs I get:
A,3
B,1
Any help much appreciated.
Create a a summary field as:
cntApplicaiton = Count of Application
Do this by going into define fields, create a field called cntApplication, type summary. In the options dialogue make the summary field a count on application
Now create a new layout with a subsummary part and nobody. The subsummary should be sorted on Application. Put the Application and cntApplication fields in subsummary. If you enter browse mode and sort by Application you ought to get the data you want.
You can also create a calc field with the formula
GetSummary(cntApplication; Application)
This will allow you to use the total number of Applications with in a record
Since I also generate the data in this form, the solution I've adopted is to fill two tables in FileMaker. One provides the summary view, the other the detailed view.
I think that your problem is down to dupliate records and an inadequate key.
Create a text field called "App_Prog". In the options box set it to an auto-enter calc, unchecking the 'Do not replace...' option, and use the following calc:
Application & "_" & Program
Now create a self join to the table using App_Prog as the field on both sides, and call this 'MatchingApps'.
Now, create (if you don't alread have one) a unique serial number field, 'Counter' say, and make sure that you enter a value in each record. (Find all, click in the field, and use serial number option in'Replace Field Contents...')
Now add a new calc field - Is_Duplicate with the following calc...
If (Counter = MatchingApps::Counter; "Master Record" ; "Duplicate")
Finally, find all, click in the 'Application field, and use 'Replace Field Contents...' with a calculation to force the auto-enter calc for 'App_Prog' to come up with a value.
Where does this get you? You should now have a set of records that are marker either "Master Record" or "Duplicate". Do a find on "Master Record", and then you can perform your summary (by Application) to do a count of distinct application-program pairs.
If you have access to custom functions (you need FileMaker Pro Advanced), I'd do it like this:
Add the RemoveDuplicates function as found here (this is a recursive function that takes a list of strings and returns a list of unique values).
In the relationships graph, add another occurrence of your table and add an Application = Application relationship.
Create a calculated field in the table with the calculation looking something like this:
ValueCount(RemoveDuplicates(List(TABLE2::Program)))
You'll find that each record will contain the number of distinct programs for the given application. Showing a summary for each application should be relatively trivial from here.
I think the best way to do this is to create a separate applications table. So as you've given the data, it would have two records, one for A and one for B.
So, with the addition of an Applications table and your existing table, which I'll call Objects, create a relationship from Applications to Objects (with a table occurrence called ObjectsParent) based on the ApplicationName as the match field. Create a self join relationship between Objects and itself with both Application and Program as the match fields. I'll call one of the "table occurrences" ObjectsParent and the other ObjectsChildren. Make sure that there's a primary key field in Objects that is set to auto-enter a serial number or some other method to ensure uniqueness. I'll call this ID.
So your relationship graph has three table occurrences:
Applications::Applicaiton = ObjectsParent::Application
ObjectsParent::Application = ObjectsChildren::Application, ObjectsParent::Program = ObjectsChildren::Program
Now create a calculation field in Objects, and calculating from the context of ObjectsParent, give it the following formula:
AppCount = Count( ObjectsChildren::ID )
Create a calculation field in Applications and calculating from the context of the table occurrence you used to relate it to ObjectsParent with the following formula:
AppCount = ObjectsParent::AppCount
The count field in Objects will have the same value for every object with the same application, so it doesn't matter which one you get this data from.
If you now view the data in Applications in list view, you can place the Applications::Application and Applications::AppCount fields on the layout and you should get what you've requested.
