There may be situations where you may need to force a full table rebuild. Please remember that in a full table rebuild a temporary table is created based on the properties of the original table, all records are read from the original table and written into the temporary table. All indexes are also rebuilt. Once all data records have been moved, the original table is deleted and the temporary table is renamed with the name of the original table. To force a table rebuild call AlterTable() with CTDB_ALTER_FULL parameter.
Delphi Example
procedure Form1.AltTable();
begin
try
CtTable1.Database := CtDatabase1;
CtTable1.Table := 'MyTable';
CtTable1.DeleteField('Age');
CtTable1.AddIndex('Index02', CTINDEX_FIXED, True, False);
CtTable1.AddSegment('Index02', 'Salary', CTSEG_SCHSEG);
CtTable1.AlterTable();
except
on E : ECtError do
Application.ShowException(E);
end;
end;
C++ Example
void Form1::AltTable()
{
try
{
CtTable1->Table = "MyTable"
CtTable1->Database = CtDatabase1;
CtTable1->DeleteField("Age");
CtTable1->AddIndex("Index02",CTINDEX_FIXED,True, False);
CtTable1->AddSegment("Index02", "Salary", CTSEG_SCHSEG);
CtTable1->AlterTable();
}
catch (ECtError& E)
{
Application->ShowException(&E);
}
}
