sqlserver with 递归用法

DECLARE @companyid TABLE ( [Id] [int] ); 
with cte as( 
    select Id from [base].[Company] where Id=123
    union all 
    select a.Id from [base].[Company] a,cte b where a.ParentId=b.Id
 )
INSERT @companyid(id) select Id from cte

 

1、with 前边的sql语句需加分号;

2、使用with变量需紧跟with语句;

3、with变量只能紧跟的使用一次;
