SQL & PL/SQL

Hello friends how are you??

You know I have a procedure that I am reviewing and is quite accessible, I just don't understand this line for what this is, I know it is to camp the error but the second line I don't understand

CREATE OR REPLACE procedure CTRB_CGA_GEN IS
g_dml_errors exception;
pragma exception_init(g_dml_errors, -24381);
begin
select count(1) from cliente;
EXCEPTION
           WHEN NO_DATA_FOUND THEN
                v_des_err := SQLERRM;
                v_est_cga := 'E';
           WHEN g_dml_errors THEN
                  g_errorCnt := SQL%BULK_EXCEPTIONS.COUNT;
                  v_des_err := SQLERRM;
                  v_est_cga := 'E';
                      IF SQL%BULK_EXCEPTIONS(g_errorCnt).ERROR_CODE = 1
                      THEN
                        v_des_err := SQLERRM;
                        v_est_cga := 'E';
                      END IF;
           WHEN OTHERS THEN
END CTRB_CGA_GEN;
