The MySQL server sends back a count indicating the total number of errors, warnings, and
notes resulting from the last statement. From the C API, this value can be obtained by calling
mysql_warning_count(). See

The following statement assigns indexes from the tables t1, t2, and
hot_cache:
mysql> CACHE INDEX t1, t2, t3 IN hot_cache;

The syntax of
be assigned to the cache. The current implementation assigns all the table's indexes to the cache, so
there is no reason to specify anything other than the table name.
The key cache referred to in a
parameter setting statement or in the server parameter settings. For example:
mysql> SET GLOBAL keycache1.key_buffer_size=128*1024;
Key cache parameters can be accessed as members of a structured system variable. See
Section 5.1.5.1, "Structured System
A key cache must exist before you can assign indexes to it:
mysql> CACHE INDEX t1 IN non_existent_cache;
ERROR 1284 (HY000): Unknown key cache 'non_existent_cache'
By default, table indexes are assigned to the main (default) key cache created at the server startup.
When a key cache is destroyed, all indexes assigned to it become assigned to the default key cache
again.
Index assignment affects the server globally: If one client assigns an index to a given cache, this cache
is used for all queries involving the index, no matter which client issues the queries.
