TQuery

At runtime I want to use a query to find the sum of a table field called value. I don't know the table name until runtime. I've tried using the Param method to set the table name, but Delphi won't play ball. Anyone got any ideas. Thanks.

You can't use a parameter for the table name. The middle layer
can't prepare the SQL-Statement
You'll have to build the query during runtime with someting
like
SQL.Clear;
SQL.Add('select count(Field) from');
SQL.Add(TableName);
