您似乎正在对所有列名称进行限定，因此您不应该收到此错误。

使用表别名可能有助于解决问题：

SELECT c.DSTBID, c.DSTB, c.BATCH, c.RATE, c.NRV, c.ACTUAL,
       c.VACTUAL, c.BONUS, c.TEAMNAME, c.GRP, c.PRD, c.VACTUALXDP,
       c.NETVALUE, c.NETVALUEXDP, c.YEAR, c.YEARMONTH,
       d.MONTH, d.DSTB, d.NRV, d.PRD, d.STOCK, d.VALUE, d.YEAR
FROM SAS.V_CUSTSAL c FULL OUTER JOIN
     SAS.V_DAILYSTOCK d
     ON c.DSTBID = d.DSTBID;

请参阅。我想我看到了问题。 NRV和YEAR出现两次。让我们给另一个别名：

SELECT c.DSTBID, c.DSTB, c.BATCH, c.RATE, c.NRV, c.ACTUAL,
       c.VACTUAL, c.BONUS, c.TEAMNAME, c.GRP, c.PRD, c.VACTUALXDP,
       c.NETVALUE, c.NETVALUEXDP, c.YEAR, c.YEARMONTH,
       d.MONTH, d.DSTB, d.NRV as ds_NRV, d.PRD, d.STOCK, s.VALUE,
       d.YEAR as ds.YEAR

我已经尝试了多次但是出现了列模糊错误
