How to update the IndexDefs property of a TTable
Problem/Question/Abstract:
Why is it that when I create a table using the TTable component's CreateTable method it creates the fields correctly but does not create the indexes even though I do a NewTable.IndexDefs.Assign(Table1.IndexDefs)?
Answer:
This is the correct way to transfer the index definition to NewTable, however, the IndexDefs property of Table1 may not be up-to-date so you need to call the Update method of Table1's IndexDefs property prior to its assignment to NewTable like this example shows:
with NewTable do
begin
Active := False;
DatabaseName := 'DBDEMOS';
TableName := 'Temp';
TableType := ttParadox;
FieldDefs.Assign(Table1.FieldDefs);
Table1.IndexDefs.Update; { Do an update first }
IndexDefs.Assign(Table1.IndexDefs);
CreateTable;
end;
