(SQL Server 2000, SP3a)
Hello all!
Is there any way to programmatically determine the ASC/DESC nature of a colu
mn in an
index?
For example, if I declare an index to be:
create unique clustered index [Test] on [MyTable](Field1 desc, Field
2)
I'd like to determine, somehow, that Field1 is declared with the DESC keywor
d.
Thanks for any help you can provide!
John PetersonAfter a bit of fiddling around, the data *appears* to be in the [dbo].&#
91;sysindexes].[keys]
column. However, I'm not sure how to interpret this data. :-(
From this link:

I wish that SQL Server had a INDEX_COLORDER() built-in function. ;-)
Any additional thoughts?

The INDEXKEY_PROPERTY function can be used to determine if
an index key is descending or ascending. Sysindexkeys system
table can help you in determining the key_id.
In SQL-DMO, you can use the GetIndexedColumnDESC method of
the Index2 object to determine if a column in an index is
descending.

based on the
31st byte of the 32 byte chunks in the sysindexes.keys, but it was rife with
disaster.
(But seemed to work!)
