私のクエリでは、平均を計算するときに、ゼロ除算エラーが発生します。Nullifを使用してこれを解決しようとしていますが、Coldfusionが「)」の近くに誤った構文を示すエラーをスローするため、構文が正しくないと思います。
私の質問は:
<cfquery name="getValueAdd" datasource="#myDSN#">
select d.partnum, sum(docunitprice * orderqty) as total_sales,
sum((c.avglaborcost + c.avgburdencost + c.avgmaterialcost + c.avgsubcontcost + c.avgmtlburcost)*d.orderqty) as total_cost,
sum((docunitprice * orderqty)-((c.avglaborcost + c.avgburdencost + c.avgmaterialcost + c.avgsubcontcost + c.avgmtlburcost)*d.orderqty)) as Value_add,
avg (isNull(
((((docunitprice * orderqty)-((c.avglaborcost + c.avgburdencost + c.avgmaterialcost + c.avgsubcontcost + c.avgmtlburcost)*d.orderqty))/ (nullIf(docunitprice * orderqty), 0),0)
))) as PercValueAdd
from orderhed h with(nolock), orderdtl d with(nolock), partcost c with(nolock)
where h.company = 'PC68300'
and d.company = h.company
and c.company = h.company
and d.ordernum = h.ordernum
and c.partnum = d.partnum
and hdcasenum = <cfqueryparam cfsqltype="cf_sql_integer" value="#rc.hdcasenum#" />
group by d.partnum
</cfquery>
誰かが私のために構文を明確にしてくれますか?
