如何将值插入动态列？

Question

declare @Columnnew varchar(50)
set @Columnnew ='NewColumn'
EXEC ('alter table dbo.Customers add '+ @Columnnew+' varchar(50)')

exec('insert into Customers ('+@Columnnew+')'+'values('+'jhj'+')')

我有这样的要求。

您错过了一些单引号。

declare @Columnnew varchar(50)
set @Columnnew ='NewColumn'
EXEC ('alter table dbo.Customers add '+ @Columnnew+' varchar(50)')

exec('insert into Customers ('+@Columnnew+')'+'values('+'''jhj'''+')')
