SQL Server 2005 Express安装程序中的排序规则配置

Question

I had to re-install my SQL Server 2005 Express instance due to a conflict with collations.

Now, once in the setup, I can't see the SQL_Latin1_General_CP1_CI_AI collation, I see "Latin1_General" instead, and I've been told is not the same.

Could you please tell me where I can find this?

Answer 1

The CI and AI bits mean "Case Insensitive" and "Accent Insenstive" (which are checkboxes in the installation dialog if I remember correctly). The CP1 part is, I think, "Code Page 1" and refers to the US region whereas without CP1, it refers to the UK region (or maybe, more generally, non-US English) - this may also be a separate selection in the installation dialog.

If you don't se these options, it will default to the codepage most suitable for the system default international settings in Windows (note: this may not be the same as your profile's international settings) at the time of installation . You can change these (both yours and the system default) via the control panel.

I've downloaded and run through the installation for SQL Server Express 2005 (SP3)...

I deselected "Hide advanced configuration options" on the "Registration Information" page (but not sure if this was necessary). On the Collation Settings" page I selected "SQL collations (used for compatibility...)" and then "Dictionary order, case-insensitive, accent-insensitive, for use with 1252 Character Set". Everything else was left on defaults.

The result was a SQL Server Express 2005 installation using the SQL_Latin1_General_CP1_CI_AI collation.
