Bind Variable in CURSOR

P: n/a
SQL Server 2000 SP4 with AWE hotfix. Windows 2003 SP1.

I have a stored procedure which is not working the way I think it
should be.

I have a CURSOR which has a variable in the WHERE clause:

DECLARE get_tabs CURSOR local fast_forward FOR
SELECT distinct tablename, id, shcontig1dt, shcontig2dt
FROM db_ind
WHERE dbname = @dbname
ORDER BY tablename

It won't return anything, even when I verify that @dbname has a value
and if I run the query in Query Analyzer with the value, it returns
rows:

SELECT distinct tablename, id, shcontig1dt, shcontig2dt
FROM db_ind
WHERE dbname = 'Archive'
ORDER BY tablename

I've taken out most of the guts for simplicity, but here's what I've
got:

GO

And this is what I'm getting:

=============================
Archive

(0 row(s) affected)

not getting any tables!
Index Maintenence complete. Job report in [DB_Rpt_Fragmentation]

..
..
..
etc.
Am I missing something obvious?

Thank you for any help you can provide!!

P: n/a

One of my fellow emps got it - apparently the CURSOR needed to be
declare w/in the loop right before I opened it.

I moved the get_tabs and get_inds cursor declarations and all is well .
