Hi,

I am writing an in house utility to attempt to compare different
aspects of databases.
I am currently writing the queries to list all of the indexes in the
database (including primary key indexes at present - I may move these
and compare separately at some point).

I would like the following information, in one result set if possible:

Table Name
Index Name
Column Name
Column Position
Unique?

Now on Oracle, this is easily done with the following query:

SELECT IND.TABLE_NAME, IND.INDEX_NAME, IND.COLUMN_NAME,
IND.COLUMN_POSITION, COL.UNIQUENESS
FROM USER_IND_COLUMNS IND,
USER_INDEXES COL
WHERE IND.INDEX_NAME = COL.INDEX_NAME
ORDER BY 1, 2, 3, 4, 5

I have been trying for over an hour now to get the equivalent, and I
really cannot figure it out. If anybody can come up with this then I
would greatly appreciate it!

Many Thanks,

Paul

Before you go too far, pay a visit to http://www.red-gate.com and
if SQL Compare meets your needs.

SELECT tablename = t.name, indexname = i.name,
colname = c.name, pos = ic.index_column_id,
indextype = i.type_desc, isunique = i.is_unique
FROM sys.tables t
JOIN sys.indexes i ON t.object_id = i.object_id
JOIN sys.index_columns ic ON i.object_id = ic.object_id
AND i.index_id = ic.index_id
JOIN sys.columns c ON t.object_id = c.object_id
AND ic.column_id = c.column_id
WHERE i.is_hypothetical = 0

There are probably more columns should include in the output, but I
levae that as an exercise.

Note: the above works in SQL 2005 only. Next time, please specify which
version of SQL Server you are using.

Hi Erland,

Thankyou very much for this. Of course, as usual I stupidly forgot to
post the version. Sorry about that. Really I need something that will
work on both SQL Server 2000 and SQL Server 2005.

Thanks for the link - unfortunately this is more of an exercise for
the time being and so we are not willing to spend money on a tool at
present!

Thanks for the help - if you do know something that will work on both
versions that would be good.

Paul

Then you need to work against sysobjects, sysindexes, sysindexkeys and
syscolumns. The query will be similar, but you need to filter for
statistics, since in SQL 2000 statistics and indexes live in sysindexes.

These are documented in Books Online, and since this is an exercise for you,
I leave you there. :-)
