我想在第二列中添加所有相同的数字,但我不知道怎么做。输出应如下所示:
+------------+------------+
| 00000030 | 106 |
| 00000001 | 106,107,125|
| 00000002 | 103 |
| 00000002 | 103 |
and so on ....
+------------+------------+
甚至可以使用简单的SQL,还是必须使用sql游标?

当然,有多种方法可以连接它。这是一种方法:
SELECT
T1.U_BaseCode,
STUFF((
SELECT
',' + CONVERT(VARCHAR(10), T2.U_FilterCode) AS [text()]
FROM [TableName] T2
WHERE T2.U_BaseCode = T1.U_BaseCode
ORDER BY T2.U_FilterCode
FOR XML PATH('')
), 1, 1, '') AS FilterCodes
FROM [TableName] T1
GROUP BY
T1.U_BaseCode
