Hi All,

I have a table in SQL Server 2000 that cannot be queried. Even a simple "select count(*) from dbo_tblAllocations" runs with no end. I've let this query run for 12 minutes with no results returned.

Here's the table:

CREATE TABLE [dbo].[dbo_tblAllocations] (
[IngAllocationsID] [int] IDENTITY (1, 1) NOT FOR REPLICATION NOT NULL ,
[Serial_Nbr] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
[IngAccountID] [int] NULL ,
[ACCT] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Invoice_Nbr] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Invoice_Date] [smalldatetime] NULL ,
[Process_Date] [smalldatetime] NULL ,
[Records] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[IngSubAccountID] [int] NULL ,
[SUB_ACCT] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[BTN] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[IngVendorID] [int] NOT NULL ,
[Vendor] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[IngLocationsID] [int] NULL ,
[IngNumbersID] [int] NULL ,
[DDN] [nvarchar] (55) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[TYPE] [nvarchar] (5) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[DESCRIPTION] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[UNIT] [nvarchar] (3) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Per_Line_Chg] [float] NULL ,
[Line_Chg] [float] NULL ,
[CDR_Chg] [float] NULL ,
[Acct_Per_Line_Chg] [float] NULL ,
[Inv_Total_Chg] [float] NULL ,
[MNTHLY] [float] NULL ,
[OTC] [float] NULL ,
[IBLD] [float] NULL ,
[OBLD] [int] NULL ,
[OUC] [float] NULL ,
[TAX] [float] NULL ,
[LATE] [float] NULL ,
[ADJ] [float] NULL ,
[CM] [int] NULL ,
[UM] [int] NULL ,
[FM] [int] NULL
) ON [PRIMARY]

Here's the indexes on the table:

index_name index_description index_keys
============================================================================
IX_dbo_tblAllocations nonclustered, unique, unique key located on PRIMARY Serial_Nbr
PK_dbo_tblAllocations clustered, unique, primary key located on PRIMARY IngAllocationsID

Here's what I get when I run sp_spaceused on the table:

name rows reserved data index_size unused
============================================================================
dbo_tblAllocations 129669 120112 KB 54432 KB 5624 KB 60056 KB

Does anyone know what could be causing this and how to fix it? From what I can tell it's just this one table and the others look fine.

Thanks,
Mark

whats the wait type when you are running the select?

can you do select top 100

are you doing this from the server, or from a client?

drop the indexes

try a simple select top 10 * from table

rebuild the indexes

or

export, drop and rebuild the table

Don't do this! This is certainly not a first step, and probably not a last step.

Find out what the cause may be.
Can you add a WHERE clause, to filter a single row, and does it return then?
Do you have any open transactions that may be blocking?
Is there some sort of process running that you may not be aware of that can be causing deadlocks?

All,

I couldn't query the table regardless of the actual SQL. I tried limiting the return data but that didn't work.

Also tried using DTS to import the table to the same DB in hopes of playing around with the copied table w/o causing any harm to the original. Same results - it hangs.

After I did an sp_who, I noted a user was still connected to the database and this user was set up to perform an import in to this table. That seemed a little coincidental and I later found out the credentials were shared so others were using it. I killed the 2 connections and the problem went away.

Thanks to everyone for the suggestions.

Mark
