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). |
