SQL Server 2008 和 SSIS - 最大列数
SQL Server 2008 中的最大列数是多少?我知道至少在 2005 年,限制与行大小有关,这仍然适用吗?
在我定义并填充这个宽得离谱的表之后,我需要针对它编写一个 SSIS 包。 SSIS 对列数的限制是否与 SQL Server 不同?
本质上,我有大量关于一个实体的属性,由于多种原因,这些属性需要存储在一个表中,然后以相同的列宽格式提取,我想确定 SQL Server 2008 中的规则是什么和 SSIS 2008。
What is the maximum number of columns witin SQL Server 2008? I know at least in 2005 the limitations were related to row size, does this still apply?
Right after I define and populate this ridiculously wide table I will need to write an SSIS package against it. Are there different limitations for SSIS for number of columns than there are for SQL Server?
In essence I have a very large number of attributes about an entity that for a number of reasons will need to be stored on one table and then extracted in that same columns wide format and I want to make sure what the rules are within SQL Server 2008 and SSIS 2008.

SQL Server 2008 有 Wide 和 NonWide 的最大值。除非您采取特殊步骤来使用稀疏列,否则您将获得一个非宽表。
行大小限制(需要注意的是,请参阅下面的规格中的详细信息):
SQL Server 2008 has a max for Wide and NonWide. Unless you've taken special steps to use sparse columns, you've got a NonWide table.
Row size limitations (with a caveat, see details in specs below):
