UPDATE table using a subquery in SQLite

问题:

I want to update records from a sub-query. I am using the following query:

UPDATE table1 SET a = aa FROM (SELECT a AS aa FROM table2) AS abc WHERE f = 1

This works fine in SQL Server. But doesn't work in SQLite.

Any Idea?

SQLite does not support UPDATE ... FROM. See https://www.sqlite.org/lang_update.html
