I create a ttParadox Table during runtime with three fields "author",
"description", "phrase" (memo). The author field should not be unique but
cppbuilder forces me to set it unique, because otherwise the program
produces errors. What am I doing wrong? In general: No field needs to be
unique but how can I set this.

Here is my code for creating the table:

Table->Active = false;
    Table->DatabaseName = Dir;
    Table->TableType = ttParadox;
    Table->TableName = "Aphorism";

    if (!Table->Exists) {
        Table->FieldDefs->Clear();

        TFieldDef *pNewDef = Table->FieldDefs->AddFieldDef();
        pNewDef->Name = "Author";
        pNewDef->DataType = ftString;
        pNewDef->Size = 255;

        pNewDef = Table->FieldDefs->AddFieldDef();
        pNewDef->Name = "Description";
        pNewDef->DataType = ftString;
        pNewDef->Size = 255;

        pNewDef = Table->FieldDefs->AddFieldDef();
        pNewDef->Name = "Phrase";
        pNewDef->DataType = ftMemo;
        pNewDef->Size = 50;

        Table->IndexDefs->Clear();
        Table->IndexDefs->Add("Autor", "Author", TIndexOptions() <<
ixPrimary << ixUnique); // Here I have to use ixUnique otherwise the program
produces errors
        Table->IndexDefs->Add("Beschreibung","Description", TIndexOptions()
<< ixUnique);

        Table->CreateTable();

        Application->MessageBox("Neue Datenbank wurde angelegt.", "Gungem
Aphorism", MB_OK | MB_ICONINFORMATION);
    }

Thank you for your help!
