mi_integer mi_tab_partnum(MI_AM_TABLE_DESC *tableDesc)

tableDesc

points to the table descriptor.

If a CREATE TABLE 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. If the table is not fragmented, the return value corresponds to the partnum value for this table in the systables system catalog table.

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