If the soccer fields are not defined in their own table, then a TIB_LookupCombo is the wrong control to choose, as it is a specialised control for linking two datasets in a KeySource-Lookup relationship.

Use a TIB_Combobox. Link its Datasource property to the main query and then link its Datafield property to the SoccerFieldName column of the query.

You populate the Items of TIB_Combobox as you prefer (just like a native VCL TDBComboBox).
