Forcing an index rebuild

There may be situations where you may need to build the indexes of a table. You can use the CTDB_ALTER_INDEX action parameter of CTTable::Alter() method to force the rebuild of all indexes of a table. when CTDB_ALTER_INDEX is specified, CTTable::Alter() will rebuild all indexes of a table regardless of any changes done to the table specification.

// rebuild all indexes

CTTable ATable(ADatabase);

// open the table

ATable.Open("MyTable", CTOPEN_NORMAL);

// rebuild all indexes
// alter the table to commit index changes to disk

try

{

ATable.Alter(CTDB_ALTER_INDEX);

}

catch (CTExplorer &err)

{

printf("Alter table failed with error %d\n", err.GetErrorCode());

}
