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). | |
