19 # This block tests that if one client modifies the database schema, a
20 # second client updates its internal cache of the database schema before
21 # executing any queries. Specifically, it does not return a "no such column"
22 # or "no such table" error if the table or column in question does exist
23 # but was added after the second client loaded its cache of the database
24 # schema.
25 #
26 # Types of schema modifications:
27 #
28 # 1. Adding a database table.
29 # 2. Adding a database view.
30 # 3. Adding a database index.
31 # 4. Adding a database trigger.
32 # 5. Adding a column to an existing table (ALTER TABLE).
