mi_integer mi_tab_partnum(MI_AM_TABLE_DESC *tableDesc)

tableDesc

points to the index descriptor.

If a CREATE INDEX or ALTER FRAGMENT statement specifies fragmentation, use this function to determine the current fragment identifier (also called a partition number). Each fragment occupies one named sbspace or extspace.

The integer specifies physical address of the fragment.

For a fragmented index, the return value corresponds to the fragment identifier and the partn value in the sysfragments system catalog table.
