此子句在另一个查询中有效

WHERE "PD"."STATUS" NOT LIKE 'C'
    AND "PD"."QUANTITY"<>"PD"."QUANTITY_REC"
    AND "PO"."Deletedflag"=0
    AND
    (
        "PO"."COBR"='5634'
        OR "PO"."COBR"='1234'
        OR "PO"."COBR"='5678'
        OR "PO"."COBR"='4321'
        OR "PO"."COBR"='8765'
    )
    AND "IM"."PUR_ON_ORDER">0
    AND "MT"."NUMber"='15'
    AND "PO"."STATUS" NOT LIKE 'C'

但是在一个新查询中，我不断收到错误消息

  

字符串'NOT LIKE'C“之后的右引号。”
