I dont do much database programming at the moment, but dont you have to set up a query, and pass that to the database.
Im really not sure what the question is : are you trying to execute a search on a single field of your database?

You'll only find the name if the field 'naam' has an index, otherwise,you'll have to use an SQL component in this way:

SELECT * FROM TACURSIST WHERE NAAM= :PNAAM

where PNAAM is a parameter passed like this:

{Set param type in  TQuery properties}

Query1.Close;
Query1.Params[0].AsString:=Edit1.Text;
Query1.Open;

Just go to Database Desktop, open the table, reestructure, and then set the field you want to have an index. It's quite simple.
The index of a table is usually a code or similar and in your case you want to have an index at alumn name, so, it's up to you.

Are you using an SQL server? (Look at Delphi on line help for IndexFieldNames).
If not, just use the index field alumn number in the table and use IndexFiles and IndexName properties.
