如何檢查mysql中的前導零的varchar

Question

條件在下面的查詢返回真實的結果，但我想要的結果。請建議我。

select * 
from test  
where 
'00160001' between '0013001' and '0023000' OR 
'00200000' between '0013001' and '0023000' 

Answer 1

如果沒有前導零，你會得到相同的結果。
使用整數數據類型來比較整數值。

你的榜樣與演員：
您也可以使用鑄轉換上飛的值

select if(cast('00160001' as unsigned) between cast('0013001' as unsigned) 
and cast('0023000' as unsigned),1,0) as test_a, 
if(cast('00200000' as unsigned) between cast('0013001' as unsigned) 
and cast('0023000' as unsigned),1,0) as test_b;
