我需要 Sybase 数据类型来保存不确定长度的字符串. [英] I need Sybase datatype to save string of indefinite Length.

问题描述

我的要求是声明一个接受最大大小的xml值的数据类型.
问题:我们在 Sybase 中有 text、xml 或 varchar(max) 数据类型吗?

My requirement is to declare a datatype which accepts xml value with maximum size.
Question: Do we have text, xml or varchar(max) datatype in Sybase?

推荐答案

有文本数据类型.您可以找到更多信息 这里.

There is text datatype. You can find More information here.

如何在程序中使用它:

create procedure settxt
(
  @txt text
)
as
begin
  select @txt
end

如何运行程序:

declare @txt  text
select @txt = 'Hello world'
execute settxt @txt

代码对我有用，但可能不适合所有人.

The code works for me, but maybe not for everyone.

这是临时表的解决方案:

Here is solution with temporary table:

create table #texttab
(
  txt varchar(100)
)
go
insert into #texttab
values ('Hello ')

insert into #texttab
values  (' wolrd!')
go
create procedure settxt
as
begin
  declare @txt text, 
          @txtval varchar(100)  

  select @txt=' '

  declare curTXT cursor for 
  select txt from #texttab


  open curTXT
  fetch curTXT into @txtval  
  while @@sqlstatus=0 begin
    select @txtval
    select @txt=@txt+@txtval
    select @txt
    fetch curTXT into @txtval
  end
  close curTXT
  deallocate cursor curTXT

  select @txt

end
go
execute settxt
