snowflake-cloud-data-platform - Snowflake 过程中 While 循环中的 IF 条件

Question

我的程序如下所示，但在这里，值没有进入在 while 循环中写入的 if 条件。请让我知道是否有人解决了这个问题。我在来自 if 条件的插入命令中使用 v_CODE，因为没有值进入此 V_CODE，程序失败并显示以下错误Undefined 'FCT.V_CODE'

您拥有基于 SELECT 查询的值的 if/else 结构。所以关于 v_CODE 的 if/else 部分没有全部执行是正常的。例如，如果 v_F_TIME_CUR 等于 v_FILTER_DESC，则不会执行以下代码：

...
else if (v_CODE=='v_'+v_FILTER_DESC.trim())
{
v_CODE=v_FILTER_ATTRIBUTE+" "+v_FILTER_CONDITION+" "+v_FILTER_VALUE;
} 

我认为您需要使用单独的“如果”条件？

if (v_BRAND == 'v_'+v_FILTER_DESC.trim())
{
v_BRAND=v_FILTER_ATTRIBUTE+" "+v_FILTER_CONDITION+" "+v_FILTER_VALUE;
};

if ( v_F_TIME_CUR =='v_'+v_FILTER_DESC.trim())
{
v_F_TIME_CUR=v_FILTER_ATTRIBUTE+" "+v_FILTER_CONDITION+" "+v_FILTER_VALUE;
};

if (v_F_TIME_PREV=='v_'+v_FILTER_DESC.trim())
{
v_F_TIME_PREV=v_FILTER_ATTRIBUTE+" "+v_FILTER_CONDITION+" "+v_FILTER_VALUE;
};
...
if (v_CODE=='v_'+v_FILTER_DESC.trim())
{
v_CODE=v_FILTER_ATTRIBUTE+" "+v_FILTER_CONDITION+" "+v_FILTER_VALUE;
}
