# There are various conditions when a server would regard mysql.event
|
|
# table as damaged:
|
|
# - the table has more column than specified in the compiled in value, but
|
|
# the version of the server which created the table is the same
|
|
# - the column count in the table is less than the compiled in value
|
|
# - some column has an incompatible type specification (for what is an
|
|
# incompatible type specification please refer to the comments in the source
|
|
#
|
|
# Unfortunately, in order to test a condition, we need to restart the
|
|
# server. Therefore, here we test only one simple case: changing the data
|
|
# type of the 'body' field to blob.
