# INDEX_SCHEMA (shows the database, or schema, in which an accessible

#       index resides),

# INDEX_NAME (shows the name of an index which the current user may access),

# SEQ_IN_INDEX (shows the ordinal position of an indexed column within

#       the index),

# COLUMN_NAME (shows the name of a column that comprises some, or all, of an

#       index key),

# COLLATION (shows how the column is sorted in the index; either A for ascending

#       or NULL for unsorted columns),

# CARDINALITY (shows the number of unique values in the index),

# SUB_PART (shows the number of indexed characters if the index is

#       a prefix index),

# PACKED (shows how the index key is packed),

# NULLABLE (shows whether the index column may contain NULL values),

# INDEX_TYPE (shows the index type; either BTREE, FULLTEXT, HASH or RTREE),
