同一句sql在php里执行没有结果，在navicat里查询有结果是什么原因？

如题，同一句sql在php里执行没有结果，在navicat里查询有结果。

SELECT
    TOP 25 SHANGPIN.SPDM,
    SHANGPIN.SPMC,
    GUIGE1.GGMC AS YS,
    SUM (VW_SDLSMX.SL) AS SL,
    FJSX3.SXMC AS SHEJI,
    FJSX4.SXMC AS DABAN
FROM
    SHANGPIN,
    GUIGE1,
    GUIGE2,
    VW_SDLSMX,
    FJSX3,
    FJSX4
WHERE
    VW_SDLSMX.SPDM = SHANGPIN.SPDM
AND VW_SDLSMX.GG1DM = GUIGE1.GGDM
AND VW_SDLSMX.GG2DM = GUIGE2.GGDM
AND VW_SDLSMX.DM1 != '900'
AND VW_SDLSMX.DM1 != '901'
AND SHANGPIN.FJSX3 = FJSX3.SXDM
AND SHANGPIN.FJSX4 = FJSX4.SXDM
AND VW_SDLSMX.SPDM IN (
    SELECT
        SPDM
    FROM
        SHANGPIN
    WHERE
        BYZD4 = '000'
    AND BYZD5 = 'eg'
)
GROUP BY
    SHANGPIN.SPDM,
    SHANGPIN.SPMC,
    GUIGE1.GGMC,
    FJSX3.SXMC,
    FJSX4.SXMC
ORDER BY
    SUM (SL) DESC

之前也遇到同样的情况，当时把语句复制到window s的记事本，再复制粘贴回回去，居然就好了。

是不是没有 commit

打印出你的sql语句看下，可能传值的时候要加引号。如：变量='$...';
