Description

Batch statement preparation fails with an assertion error if multiple tables and parameters are used.

BEGIN BATCH 
 UPDATE tbl1 SET v1 = 1 WHERE k1 = ?
 UPDATE tbl2 SET v2 = 2 WHERE k2 = ?
APPLY BATCH

The logic for affectsMultipleTables here looks inverted
This later causes an assertion failure here
