計算案例陳述產生的結果

Question

我正在研究一個分析兩個記錄並檢查一個記錄是否與第二個記錄匹配的查詢。 如果記錄1列與記錄2列匹配，則沒有錯誤。 如果記錄1列與記錄2列不匹配，則存在錯誤。 我希望能夠計算每個YPID的錯誤。 為了我的生命...我無法解決。 救命！

這是我的查詢：

ls.presence_score, ls.listing_score,

when r1.business_name = r2.business_name then 'no_error'

end Business_Name_Status,

when r1.longitude = r2.longitude then  'no_error'
when r1.latitude is null or r1.latitude in ('0') then (case when r1.street_address = r2.street_address then 'no_error' else 'error' end)

Answer 1

我想您需要使用LEAD，LAG功能。

檢查此鏈接http://oracle-base.com/articles/misc/lag-lead-analytic-functions.php

LAG函數用於訪問上一行的數據。LEAD函數用於返回下一行的數據。

通過這個你可以比較第一行和第二行
