Easy, I guess you could've sorted it out searching on google:
df.dropna()

This might be a very stupid question but for the life of me I can't get it to work. I want to create a field in my table called "One" and it's value for all records in the table needs to be 1.
E.G.
Field1 One
A 1
B 1
C 1
.
.
.
I set the field to a number and tried the auto enter data and typed 1 in the data field but it's not updating the values.
Any help is greatly appreciated!
Thanks in advance
Simply put, Auto Enter applies to when the record is first created. One can do various other options, but this is the basic use of Auto Enter on a field. You set the value to be auto-entered in the field's options panel under Manage Database; a fixed value, calculated value and so on. This works on all versions of FileMaker.
That said, if this is to be a static value of 1 for all records, you might want to look into a calculation field with a result of 1 and possibly using global storage. This will not work if you need the user to be able to change the value.
How do I tell Filemaker what table to paste a value into based on the value? Is there a way to somehow have Filemaker paste a value into a table without hard coding the table name?
Using imported transaction data, I determine which ledger (table) the transaction should be posted to. But I can't seem to get the script to then post it into the right table based on the value.

Thanks for the thoughtful suggestions!
I found a way to do what I was thinking, #AndreasT your suggestion helped.
Case (
Imported_Transactions::Debit_To = "Expenses_All"; "Expenses_All::Description";
Imported_Transactions::Debit_To = "Liability_CrCard_BofA"; Liability_CrCard_BofA::Description;
Imported_Transactions::Debit_To = "Liability_CrCard_CitiBusiness"; Liability_CrCard_CitiBusiness::Description;
)
Using the Case function, I was able to get Filemaker to put the data in the right table. It took some doing, but by putting the tablename::field in quotes, it worked.
Ultimately, though, I found it easier to just use one table and field descriptors to store my data. Simplicity makes it easier to produce reports.
You could use the conditional If script step to determine what table to insert data into based on your input.
Set field by name[ tablename::fieldname ; value ]
I have a table in my postgres database, with a list of buildings called Buildings_national. In this table, I have a larger number of duplicates, and i need to point them out to have the duplicates deleted.
The thing is, that I need to leave out a single line for every duplicate group, to make sure that one example of the duplicated building is retained in the table.
All buildings has a unique identifier, and every line has a unique identifier as well.
Can anyone recommend a good way to do this? I guess what I am looking for, is a reversed distinct somehow?
I am implementing a GWT CellTable with paging and sorting by multiple columns dynamically.
The basics can be found in the CellTable Developer's Guide.
However, the dynamic example does not tell how to find out by which column the user wants to sort (it simply sorts by the 'name' column). That's not enough in my case, as I want to allow the user to sort by different columns.
The only solution I could think of, which is not very elegant, is to keep track of which column is sorted in ascending order or not (using table.getColumnSortList(indexOfColumn).isAscending()) and then figuring out which one has been clicked by comparing the values for each column (the one that changed is probably what the user clicked).
This involves keeping information in my classes that should be available somewhere in the CellTable! But I can't find that information!
Thanks for any help.
I found the answer. As explained in the javadocs for com.google.gwt.user.cellview.client.ColumnSortList:
An ordered list containing the sort history of Columns in a table. The 0th item is the ColumnSortInfo of the most recently sorted column.
So, to know which column was last sorted by, you simply do:
ColumnSortInfo info = table.getColumnSortList().get(0);
Column<Type> sortByColumn = info.getColumn();
I'm using a dictionary and an array to store the section title for a table view, along with the number of rows in each. I'm adding to the array and the dictionary in a loop of the records from my database in mu populateDataSource method.
I've got two dates from three records in my database. 2010-11-05 and 2010-11-07
I'm not sure if its because the table view events need to start at zero and the dictionary / array start at one ?
Or maybe my sectionTitles addObject, is added values each time, rather than adding unique dates. If so how i can search or only allow unique values ?
Any ideas ?
Arrays have a starting index of 0, but dictionaries don't essentially work that way. What is the purpose of the dictionary in this case? To get an object from the dictionary you give it a key. If you're going through a loop and not getting the expected result, maybe the dictionary isn't getting the key that it should be.
