Question

找到無與倫比的數據我有這2個簡單的表格

我想在SAMPLE2 到目前爲止，我已經嘗試

SELECT * FROM SAMPLE1,SAMPLE2 WHERE SAMPLE1.FruitName NOT LIKE '%' + dbo.SAMPLE2.FruitName +'%' 

比較FruitName選擇從SAMPLE1不匹配的數據，但是這給了我共7條 我想輸出是

Answer 1

SELECT * 
FROM SAMPLE1 s1 
WHERE NOT EXISTS (
     SELECT NULL 
     FROM SAMPLE2 s2 
     WHERE s1.FruitName LIKE '%' + s2.FruitName + '%' 
     ) 

Answer 2

試試這個：

SELECT * FROM SAMPLE1,SAMPLE2 WHERE SAMPLE1.FruitName NOT LIKE '%' + dbo.SAMPLE2.FruitName +'%' AND SAMPLE1.id = SAMPLE2.id 

必須確保您比較相同的ID。

Answer 3

也許這幫助：

select SAMPLE1.* from SAMPLE1 
Left join SAMPLE2 ON SAMPLE1.fruitName LIKE concat('%', SAMPLE2.fruitName, '%') 
Where SAMPLE2.id is null
