CACHE-TABLE-QUERIES — Control the caching of table attribute types.Function
table
A string representing a database table, T or
:default.
action
T, NIL or :flush.
databaseA database object. This will default to the value of *default-database*.
Controls the caching of attribute type information on the
table specified by table in
database which defaults to
*default-database*. action
specifies the caching behaviour to adopt. If its value is T
then attribute type information is cached whereas if its value
is NIL then attribute type information is not cached. If
action is :flush then
all existing type information in the cache for
table is removed, but caching is still
enabled. table may be a string
representing a table for which the caching action is to be taken
while the caching action is applied to all tables if
table is T. Alternatively, when
table is :default, the
default caching action specified by
*cache-table-queries-default* is applied to all
tables for which a caching action has not been explicitly set.
