我无法获得表格格式的输出。

DECLARE
    prev    VARCHAR2(10) := 'sysdate+1';
    tdy     VARCHAR2(10) := 'sysdate';
    v_dt    VARCHAR2(10);
    result  resultset;
BEGIN
    v_dat :=
        CASE
            WHEN trunc(sysdate) = trunc(currnet_date) THEN
                tdy
            ELSE prev
        END;

    WITH 
     yesterday AS (
        SELECT
            src_dim_id,
            rec_count
        FROM
            tab_total_last_updated
        WHERE
                to_char(dw_insert_datetime, 'mm-dd-yy') = CASE
                                                              WHEN TRIM(to_char(v_dt, 'DAY', 'NLS_DATE_LANGUAGE=ENGLISH')) =
                                                              'MONDAY' THEN
                                                                  to_char(v_dt - 3, 'mm-dd-yy')
                                                              ELSE
                                                                  to_char(v_dt - 1, 'mm-dd-yy')
                                                          END
            AND table_type = 'EXT'
    )
    SELECT
        *
    INTO result
    FROM
        yesterday;
    RETURN result;
END;

我试图根据条件将值sysdate传递到v_dt，但我无法继续我的代码，请帮助解决这个问题。
