Answer 1

PATINDEX应该找到给定表达式的第一个位置。在这种情况下，一个数字。因此，您根据找到该数字的位置进行拆分。对名称的SUBSTRING采用数字前的任何文本，名称后的SUBSTRING采用以数字开头的任何文本。

SELECT SUBSTRING(COL_DETAILS, 1, patindex('[0-9]',col_details)-1) col_name,
    SUBSTRING(COL_DETAILS, patindex('[0-9]',col_details), len(COL_DETAILS)) col_salary
FROM TABLE

Answer 2

请找到以下脚本

Declare @EmpData AS TABLE (col_details Varchar(100))
INSERT INTO @EmpData
SELECT 'Sam100'   UNION ALL
SELECT 'Ram200'   UNION ALL
SELECT 'Sam1000'  UNION ALL
SELECT 'Ram50000' UNION ALL
SELECT 'Aryan450'

SELECT EmpNAme,SUM(Sal) AS col_salary
 FROM 
(
SELECT col_details,
SUBSTRING(col_details,0,PATINDEX('%[0-9]%',col_details))AS EmpNAme,
CAST(SUBSTRING(col_details,PATINDEX('%[0-9]%',col_details), LEN (col_details)) AS INT)AS Sal FROM @EmpData
)dt
GROUP BY EmpNAme
ORDER BY EmpNAme DESC

结果

EmpNAme col_salary
------------------
Sam     1100
Ram     50200
Aryan   450
