如何将查询的记录都合并成为一个记录呢?其实实现的SQL语句写法并不复杂,下面就为您列出该SQL语句,希望对您学习SQL语句有所启迪。
- create table t
- (tableid nchar(30))
- insert t
- select ’T1’ union all
- select ’T2’ union all
- select ’T3’ union all
- select ’T4’ union all
- select ’T5’ union all
- select ’T6’
- go
- create function f_he()
- returns @t table(col varchar(50))
- as
- begin
- declare @sql varchar(50)
- set @sql=’’
- select @sql=@sql+ltrim(rtrim(tableid)) from t
- insert @t values (@sql)
- return
- end
- go
- select * from t
- select * from dbo.f_he()
- drop function f_he
- drop table t
- col
