Currently I have to use 2 statements to handle it, one plain SELECT COUNT(*) AS NUMBER FROM TABLE WHERE CONDITION, and the second statement performs actual update/deletion. It would be useful if SQLExecutor is able to expose number of rows affected bu UPDATE, DELETE commands.

That could be a useful function, but in some database formats, you can do that with a SQL statement. In PostgreSQL, for example, you can use the "returning" parameter in delete/update statement to get affected rows. These statements return the number of deleted/updated rows.
FME_SQL_DELIMITER ; with deleted_rows as (delete from <table name> where <condition> returning *) select 'delete' as command, count(*) as num_affected from deleted_rows; with updated_rows as (update <table name> set <column>=<value> where <condition> returning *) select 'update' as command, count(*) as num_affected from updated_rows;FYI.
