我有一个列联表,并希望将其插入到SQL Server数据库中:
列联表:
| | soccer | football | basketball |
+------+---------+-----------+-------------
| Max | x | | x |
| Mary| x | | |
| Tim | | | x |
+------+---------+-----------+-------------
应通过T-SQL INSERT转换为:
| name | sports |
+------+---------+
| Max | soccer |
| Max | basketball
| Mary | soccer |
| Tim | basketball
+------+---------+
现在可以在SQL Server中使用SQL吗?
非常感谢。

如果这是xls数据,您可以运行直接脚本将相同的数据插入SQL Server表。然后,您可以为每项运动运行不同的INSERT
查询,以使其符合您所需的格式,并删除原始表格。
假设原始表中的第一列被称为Name
:
INSERT INTO [TableB] (Name, Sports)
SELECT Name, 'Soccer'
FROM [TableA]
WHERE Soccer=1
INSERT INTO [TableB] (Name, Sports)
SELECT Name, 'Football'
FROM [TableA]
WHERE Football=1
INSERT INTO [TableB] (Name, Sports)
SELECT Name, 'Basketball'
FROM [TableA]
WHERE Basketball=1
