Autocomplete breaks after Where statement

### Description

There is still a bug in autocomplete. Steps to replicate:
1. Have two tables to join with aliases each. Fill the columns of interest in the Select clause.
2. When you come to WHERE clause, if you have the first condition such as bn.column_name the autocomplete works.
3. But add another condition with AND and the autocomplete breaks for everywhere in the whole query.
