Is there anywhere within the actual database itself that lists the database name. I know that it's stored in Master but I wasn't sure if there was a way to pull it from a column in the database itself?

Let me be more specific. This is a piece of a stored procedure I'm working on. I need to add a line that will grab the current database name that the stored proc is being run against. Later in the stored procedure I'm inserting this information into a table. Can anyone tell me what I can add to grab the current database name AS "Database Name"?

[red]BEGIN
SELECT @SELECT = N'USE ' + @DbName + N' SELECT ' + ISNULL(@TopClause, N' ') +
N''''' + USER_NAME(o.uid) + ''.'' + OBJECT_NAME(i.id) + '''' AS ''ObjectName'',
o.type AS ''Type'',
MAX(i.[rows]) AS ''Rows'',
CONVERT(dec(10,3), SUM(i.reserved * 8.000/1024)) AS ''Total(MB)'',
CONVERT(dec(10,3), SUM((i.reserved - i.used) * 8.000/1024)) AS ''Unused(MB)'',
CONVERT(dec(10,3), SUM(i.used * 8.000/1024)) AS ''Used(MB)'',
CONVERT(dec(10,3), SUM((i.used - CASE WHEN indid <> 255 THEN i.dpages ELSE i.used END)
* 8.000/1024)) AS ''Index(MB)'',
CONVERT(dec(10,3), SUM(CASE WHEN indid <> 255 THEN i.dpages ELSE i.used END
* 8.000/1024)) AS ''Data(MB)''
FROM dbo.sysindexes i WITH (NOLOCK)
JOIN dbo.sysobjects o WITH (NOLOCK)
ON i.id = o.id
WHERE i.name NOT LIKE ''_WA_Sys_%''
AND i.indid IN (0, 1, 255) AND USER_NAME(o.uid) LIKE ''' + ISNULL(@SchemaName, N'%') + N''' ',
-- SS 2000 calculation as below:
-- "reserved" = total size;
-- "dpages" = data used;
-- "used" = used portion (contains data and index);
-- text or image column: use "used" for data size
-- Nonclustered index take tiny space, somehow it is not counted (see sp_spaceused).
@WHERE_Final = N' AND OBJECT_NAME(i.id) LIKE ''' + ISNULL(@ObjectName, N'%')
+ N''' AND o.type IN (' + @ObjectType + N') ',
@GroupBy = N' GROUP BY '''' + USER_NAME(o.uid) + ''.'' + OBJECT_NAME(i.id) + '''', o.type ',
@String = @SELECT + @WHERE_Final + @GroupBy + @OrderBy
END

Thanks!

What about the function DB_NAME()



SELECT DB_NAME()

Oh, I forgot to mention I'm running this in SQL Server 2000 so the "SS 2000" section is the one I'm using.

Nevermind, I figured that out. Now I just need to know how to add a current Date/Time field and have it pull the current date time?

Does anyone know how best to do this?

Thanks so much!!

same as before really..

SELECT getDate() returns current (database server) date and time
