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