Question

我想知道是否有办法让这个动态sp变为非动态sp

CREATE PROCEDURE [dbo].[GetPeople]
    (
        @id varchar(8) = NULL,
        @lastName varchar(50) = NULL,
        @firstName varchar(50) = NULL,

        @ssn varchar(9) = NULL,
        @driversLicense varchar(12) = NULL,
        @gender varchar(1) = NULL,

        @addressNumber varchar(8) = NULL,
        @addressFraction varchar(3) = NULL,
        @addressDirection varchar(3) = NULL,
        @street varchar(45) = NULL,
