Note: Google changed the DELETE logic and you do not need the ROWIDs anymore to delete rows, just use your WHERE condition instead.
See the the SQL Reference Documentation of the Fusion Tables API.
For DELETE statements the first step to be done is to get the ROWID of the row to be deleted with a SELECT statement. The second step is to do the DELETE.
Step 1 (to get the list of rowids to be deleted) will be executed only once and Step 2 (to delete a row) will be executed several times as much as rowids are in the list.
To find out, if the first SQL statement is correct, after entring a name in the textbox, right click onto the join block of the sql statement
and select Do it.
Forgetting spaces is a frequently made error, see also Frequently Made Errors with Fusiontables and how to fix them
To find out, if the second SQL statement is correct, disable the SendQuery block in Step 2, then click onto the "Delete my order" button and after the select statement has been executed and a rowid has been found in the table, then right click onto the join block of the sql statement and select Do it like this:
Q1: Actually under the ID in some row, I have the same ID. So actually if I delete, I want to delete the multiple row that have the same ID.
Am I able to do that?
A: See ABG's answer here: You keep a list of the rowIDs you want to delete, and send away one request for the first DELETE. After you get the receipt that it was deleted, take it off your list and send off the new one at the head of the list. Stop when the list is empty. See the updated example how to do it. An other example of the same method you can find in my filebyfile example.
