De la ayuda de Delphi:

Execute method (TADOCommand)

Delphi syntax:

function Execute: _Recordset; overload;
function Execute(const Parameters: OleVariant): _Recordset; overload;
function Execute(var RecordsAffected: Integer; const Parameters: OleVariant): _RecordSet; overload;

[...]

Description

Call Execute to immediately execute the command specified in the CommandText property.

RecordsAffected indicates the number of records, if the command operates on data, that are affected by the command after execution.

Parameters is a collection of parameters for the command, unnecessary if the command does not use any parameters.
