Answer 1

在 SQL 中，你可以在patindex()子句中使用order by函数

order by patindex('%[a-z]%', col), ?;

但是，?指定表数据排序的实际col

Answer 2

试试这个......

               SELECT '45'  AS Val
               INTO Temp
               UNION ALL SELECT '55'
               UNION ALL SELECT '155'
               UNION ALL SELECT '47'
               UNION ALL SELECT 'AB'
               UNION ALL SELECT '56'
               UNION ALL SELECT 'AC'
               UNION ALL SELECT '43'
               UNION ALL SELECT 'DSE'


               SELECT *
               FROM Temp
               ORDER BY Val

您还可以尝试以下查询

DECLARE @Table TABLE(col1 VARCHAR(10))
INSERT INTO @Table VALUES(45)
INSERT INTO @Table VALUES(55)
INSERT INTO @Table VALUES(47)
INSERT INTO @Table VALUES('AB')
INSERT INTO @Table VALUES(56)
INSERT INTO @Table VALUES('AC')
INSERT INTO @Table VALUES(43)

SELECT Col1
FROM @Table
WHERE ISNUMERIC(col1) = 1
UNION
SELECT * FROM @Table WHERE ISNUMERIC(col1) = 0 ORDER BY Col1 ASC
