按表列划分

Question

我能知道为什么分频器没有显示价值吗？

- (void)applicationDidEnterBackground:(UIApplication *)application
{

    // Change the rootViewController of your window.. 
}

最后一列的值始终显示为0.不应该是columnA / 12？

    select gg.columnA ,t.columnB, (gg.columnA / t.columnB) as C
    FROM #main t
LEFT OUTER JOIN #Total_ByGradeGender gg
    ON t.OrganizationCd = gg.OrganizationCd
    AND t.CountryCd = gg.CountryCd
    where t.organizationcd = '27849' 

如果我将分频器更改为整数，则显示该值。

Answer 1

您需要转换为数字

select gg.columnA ,t.columnB, (gg.columnA /cast( t.columnB as numeric))  as C
   FROM #main t
LEFT OUTER JOIN #Total_ByGradeGender gg
ON t.OrganizationCd = gg.OrganizationCd
AND t.CountryCd = gg.CountryCd
where t.organizationcd = '27849'
