如下是创建表的index in 子句的说明：

INDEX IN tablespace-nameIdentifies the table space in which any indexes on a nonpartitioned table or nonpartitioned indexes on a partitioned table are to be created. The specified table space must exist; it must be a DMS table space if the table has data in DMS table spaces, or an SMS table space if the partitioned table has data in SMS table spaces; it must be a table space on which the authorization ID of the statement holds the USE privilege; and it must be in the same database partition group as tablespace-name (SQLSTATE 42838).

Specifying which table space will contain indexes can be done when a table is created or, in the case of partitioned tables, it can be done by specifying the IN clause of the CREATE INDEX statement for a nonpartitioned index. Checking for the USE privilege on the table space is done at table creation time, not when an index is created later.

For a nonpartitioned index on a partitioned table, storage of the index is as follows:

• The table space by the IN clause of the CREATE INDEX statement
• The table-level table space specified for the INDEX IN clause of the CREATE TABLE statement
• If neither of the preceding are specified, the index is stored in the table space of the first attached or visible data partition(如果前面两个都未指定，则索引存储在第一个附加的或可见的数据分区的表空间中)

For information about partitioned indexes on partitioned tables, see the description of the partition-element INDEX IN clause.
