基本上,我希望能够基于现有表动态创建临时表,然后将值插入临时表,并选择插入的值。
我已经有了创建临时表的部分,它工作得很好,只是插入和选择表单,它工作得不太好。
这是我目前的密码。
declare @table table
(
OrdinalPosition int,
ColumnName nvarchar(255),
DataType nvarchar(50),
MaxChar int,
Nullable nvarchar(5)
)
declare @i int
declare @count int
declare @colname nvarchar(255), @datatype nvarchar(50), @maxchar int
declare @string nvarchar(max)
declare @tblname nvarchar(100)
set @tblname='Projects'
set @string='create table #' + @tblname + ' ('
insert into @table
(
OrdinalPosition,
ColumnName,
DataType,
MaxChar,
Nullable
)
SELECT

set @i=1
select @count=count(*) from @table

begin

begin

set @i=@i+1
end
