The mi_tab_partnum() accessor function
The mi_tab_partnum() function retrieves the fragment identifier for the index.
Syntax
mi_integer mi_tab_partnum(MI_AM_TABLE_DESC *tableDesc)- tableDesc
- Points to the index descriptor.
Usage
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.
Return values
The integer specifies physical address of the fragment.
For a fragmented table, the return value corresponds to the fragment identifier and the partn value in the sysfragments system catalog table.
