How do i delete all values in one column 

you only can delete rows, but you can update all values in a column and set them to empty string like this:

generally: For UPDATE statements the first step to be done is to get the ROWID of the row to be updated with a SELECT statement. The second step is to do the UPDATE.

see also SQL Reference Documentation of the Fusion Tables API.

to update several rows, you first could retrieve the rowids of all rows like this

SELECT ROWID FROM <tableid>

and store them in a list, then execute an update statement for each rowid

UPDATE <tableid> SET myColumn = '' WHERE ROWID = <rowid>

how do i only get the last value in a column

you can try the following slect statement

SELECT columnName FROM <tableid> WHERE ROWID = MAXIMUM(ROWID)
