Question

I get this exception:

FATAL EXCEPTION: main android.database.sqlite.SQLiteException: near ".": syntax error: , while compiling: UPDATE items SET I.red='1' FROM items I, feeds F  WHERE I.feedLink=F.link AND F.category='Genel'

from this statement:

UPDATE items 
SET I.red='1' 
FROM items I, feeds F 
WHERE I.feedLink=F.link AND F.category='Genel'

using SQLite in Android. How can I solve this?

Note: items and feeds are names of my datebase tables.

Answer 1

SQL UPDATE syntax:

UPDATE table_name
SET column1=value, column2=value2,...
WHERE some_column=some_value

To hone in on what I think you’re trying to accomplish:

UPDATE items 
SET red='1' 
WHERE feedLink IN 
(SELECT link FROM feeds WHERE category='Genel')
