有人可以帮我调试以下if语句吗？它给我错误

drop temporary table if exists tempdb.outcome;

if ('2017-01-01' >=  @TSTARTDATE AND @TSTARTDATE < '2018-09-23'  ) THEN

CREATE temporary TABLE IF NOT EXISTS tempdb.outcome
select distinct 
  row_id, odr_item_row_id, region_id, createdby, mdn, product_id, billling_acct_id, order_num, 
  order_entry_ts, install_dt, curr_sts_dt, valid_dt, prov_dt, product, order_type,order_reason, 
  odr_act_base, datarate , pkg, 
  max(new_priceplan ) New_PricePlan, max(old_priceplan) Old_PricePlan, 
  replace(replace(max(new_priceplan ),'_Old',''),' ', '') as New_PricePlan_fj , 
  replace(replace(max(old_priceplan),'_Old',''),' ', '') as Old_PricePlan_fj,
  UPFRNT_AMT 
from tablea 
WHERE ORDER_ENTRY_date >=@TSTARTDATE AND ORDER_ENTRY_date <@TENDDATE 
      and product = 'Broadband'
      and order_type in ('new order', 'modify order','terminate order')
      and odr_act_base in ('Add','Update', 'delete') 
group by row_id, odr_item_row_id, region_id, createdby, mdn, product_id, billling_acct_id, order_num,
         order_entry_ts , install_dt, curr_sts_dt, valid_dt, prov_dt, product, order_type,order_reason,
         odr_act_base, datarate,pkg ;

这是错误消息：如果（'2017-01-01'> = @TSTARTDATE AND @TSTARTDATE 如果不存在则创建临时表tempdb.outcome选择不同的row_id，odr_item_row_id，region_id，创建者，mdn，product_id，billling_acct_id，order_num，order_entry_ts，install_dt，curr_sts_dt，valid_dt，prov_dt，产品，order_type，order_reason，odr_act_base，datarate，pkg，max（new_priceplan）New_PricePlan，max（old_priceplan）Old_PricePlan，将replace（replace（max（new_priceplan），'_ Old'，''），''，''）作为New_PricePlan_fj，replace（replace（max（old_priceplan），'_ Old'，''），''，''）为Old_PricePlan_fj，UPFRNT_AMT来自ptclsatmap_archival。ptclsales.orders_20161001_20180923WHERE ORDER_ENTRY_date> = @ TSTARTDATE AND ORDER_ENTRY_date = @TSTARTDATE AND @TSTARTDATE

在行1 0.000秒处创建'

有人可以帮我调试以下if语句吗？如果存在tempdb.outcome，它会给我错误删除临时表；如果（'2017-01-01'> = @TSTARTDATE AND @TSTARTDATE

您应在分组结果中不涉及的所有列中分组提及（在您错过的代码中，New_PricePlan_fj和Old_PricePlan_fj）

CREATE temporary TABLE IF NOT EXISTS tempdb.outcome
select  row_id
  , odr_item_row_id
  , region_id
  , createdby
  , mdn
  , product_id
  , billling_acct_id
  , order_num
  , order_entry_ts
  , install_dt
  , curr_sts_dt
  , valid_dt
  , prov_dt
  , product
  , order_type
  , order_reason
  , odr_act_base
  , datarate 
  , pkg
  , max(new_priceplan ) New_PricePlan
  , max(old_priceplan) Old_PricePlan
  , replace(replace(max(new_priceplan ),'_Old',''),' ', '') as New_PricePlan_fj 
  , replace( replace(max(old_priceplan),'_Old',''),' ', '') as Old_PricePlan_fj
  ,UPFRNT_AMT
from tablea
WHERE ORDER_ENTRY_date >=@TSTARTDATE AND ORDER_ENTRY_date <@TENDDATE
and product = 'Broadband' 
and order_type in ('new order', 'modify order','terminate order')  
and odr_act_base in ('Add','Update', 'delete')
group by row_id
  , odr_item_row_id
  , region_id
  , createdby
  , mdn
  , product_id
  , billling_acct_id
  , order_num
  , order_entry_ts 
  , install_dt
  , curr_sts_dt
  , valid_dt
  , prov_dt
  , product
  , order_type
  , order_reason
  , odr_act_base
  , datarate
  , pkg 
  , New_PricePlan_fj
  , Old_PricePlan_fj;

您不需要区分，因为您有一个分组依据（这不是错误，但是区分是没有用的]
