Mysql 将CAST（）与MAX（）/MIN（）一起使用

我有一些街道号码存储为VARCHARs，但我想尽可能将它们作为int进行排序。此语法被接受，但会生成alpha排序集，如max=53、min=1203

SELECT  `StreetName`, 
CAST( MIN( `StreetNumber` ) AS UNSIGNED)  as min,
CAST( MAX( `StreetNumber` ) AS UNSIGNED)  as max
FROM  `tblAddToLotBridge` 
WHERE  `LotNumber` = '$item_lotnum'
AND `Primary_Secondary` = 0 
GROUP BY `StreetName`
ORDER BY `StreetName`

我尝试在

MIN（）

/

MAX（）

中嵌套

CAST（）

，但该语法被拒绝

什么是DWIM的正确sytax？

这是您尝试的吗

SELECT  `StreetName`, 
MIN( CAST( `StreetNumber` AS UNSIGNED) ) as min,
MAX( CAST( `StreetNumber` AS UNSIGNED) ) as max
FROM  `tblAddToLotBridge` 
WHERE  `LotNumber` = '$item_lotnum'
AND `Primary_Secondary` = 0 
GROUP BY `StreetName`
ORDER BY `StreetName`
