无效的标识符

查询：

    KRDFAS.NOFAS, MSTCST.CNM, MSTCST.REFERENSI, KRD100.PLF_DEBITUR,
    TBL_GROUP.NAMA_GROUP, ACOFF.NM_AO, MSTCST.KETERANGAN 
FROM 
    KRD100
INNER JOIN 
    KRDFAS ON KRD100.NOFAS = KRDFAS.NOFAS
INNER JOIN 
    MSTCST ON KRDFAS.CNO = MSTCST.CNO AND MSTCST.ALTERNATE = KRDFAS.ALTERNATE
INNER JOIN

                     FROM TBLAREA 
                     WHERE KDAREA = :kd_area) 
    AND KRDFAS.STSKRD = 'OK' 
    AND PRODUK.KD_PRODUK LIKE :kd_produk;

Dimas，      您引用的表'User'未包含在select语句中。您引用的用户字段为user.usrnm，但语句中没有描述表'user'的表。
