如何在SQL Server中将多行员工合并为一行
我有下表，下面是预期结果。请告诉我是否有一种简单的方法可以在SQL server中获得预期的结果如何在SQL Server中将多行员工合并为一行,sql,sql-server,pivot,Sql,Sql Server,Pivot,我有下表，下面是预期结果。请告诉我是否有一种简单的方法可以在SQL server中获得预期的结果 EmpNo Name Benefit StartDate Status -------------------------------------------- 0001 ABC Medical 01/01/2014 Active 0001 ABC Dental 02/02/2013 Inactive 0001 ABC Vision

3） 此外，还有多个字段与每行关联，例如，选择选项（Self、Family等）等等。简单地说，我没有包括在问题中。我假设每个员工最多有一行用于医疗，最多一行用于牙科，最多一行用于视力。如果是这样，您可以这样做：
