CTTable::GetStatus

Declaration

ULONG CTTable::GetStatus();

Description

Retrieves the table status. The table status indicates which rebuild action will be taken by an alter table operation.

Return Values

GetStatus() returns CTDB_REBUILD_NONE if the table is not changed or a bit mask of the values below describing the table status.

The possible rebuild status returns are:

Rebuild Status Value	Rebuild Status Symbolic Code	Explanation
0	CTDB_REBUILD_NONE	Nothing to be done, no changes to table
1	CTDB_REBUILD_DODA	Update the table DODA
2	CTDB_REBUILD_RESOURCE	Update table FC!DFLD resource
4	CTDB_REBUILD_INDEX	Add new indices to table
8	CTDB_REBUILD_ALL	Rebuild all indices
16	CTDB_REBUILD_FULL	Full table rebuild. A temporary table is created and all data is moved to new table and the indexes are built on the fly.

Example

ULONG status = hTable.GetStatus();

if (status & CTDB_REBUILD_ALL || status & CTDB_REBUILD_FULL)

hTable.Alter(CTDB_ALTER_FULL)

else if (status)

hTable.Alter(CTDB_ALTER_NORMAL);
