Question

我有一个存储过程

ALTER PROCEDURE [dbo].[solar_zip_tier_acl_zip_export]
@affiliate_id int
 AS
BEGIN
SET NOCOUNT ON;
declare @tier_date  varchar(6)
exec solar_zip_tier_select_active_date @tier_date output

SELECT DISTINCT
    zip,
    state
FROM solar_zip_tier_mapping_view sztm (NOLOCK)
JOIN solar_zip_tier_acl acl (NOLOCK)
    ON acl.tier_id = sztm.tier_id
    AND (acl.buyer_id = sztm.buyer_id
    OR acl.buyer_id = 0)
JOIN buyers b (NOLOCK)
    ON b.buyer_id = sztm.buyer_id
JOIN solar_zip_tiers szt (NOLOCK)
    ON szt.tier_id = sztm.tier_id
WHERE sztm.tier_date = @tier_date
AND acl.affiliate_id = @affiliate_id
AND sztm.active > 0
AND b.active > 0
AND szt.active > 0
ORDER BY zip

返回结果的方式是

Zip     State

  01001   
  01001   MA

  01002   
  01002   MA

  01003   
  01003   MA

它产生了2行，其中一行有状态，另一行没有状态，我该怎么修改它，所以只产生带数据的行？我希望结果为

Zip   State

  01001  MA

  01002  MA

  01003  MA

SELECT DISTINCT
    zip,
    state
FROM solar_zip_tier_mapping_view sztm (NOLOCK)
JOIN solar_zip_tier_acl acl (NOLOCK)
    ON acl.tier_id = sztm.tier_id
    AND (acl.buyer_id = sztm.buyer_id
    OR acl.buyer_id = 0)
JOIN buyers b (NOLOCK)
    ON b.buyer_id = sztm.buyer_id
JOIN solar_zip_tiers szt (NOLOCK)
    ON szt.tier_id = sztm.tier_id
WHERE sztm.tier_date = @tier_date
AND acl.affiliate_id = @affiliate_id
AND sztm.active > 0
AND b.active > 0
AND szt.active > 0
AND STATE IS NOT NULL AND STATE IS NOT ''
ORDER BY zip

存储过程返回重复的行，其中一列为空
