determine if temp table exists

I need to determine a way to search if a tempory table exist before atteptin
g
to read a record from it.
The only way I know of is to perform the following:
if exists(select * from tempdb..sysobjects where name like '#tablename%'
and type='U')
However, if there are multiple sessions on the same machine, this may pass
but the current session doesn't have an existing temporary table. Is there
a
way to determine that a temporary table listed in sysobjects is for the
current session?Try:
IF OBJECT_ID('tempdb..#tablename') IS NOT NULL

Detect Stored Procedure that refer to tables that do not exist

It is possible to construct a query that will list all stored procedures
that refer to tables that no longer exist in the database?
Thanks,
ChrisHi
Execute each SP with "SET NOEXEC ON" set.
From BOL
"The execution of statements in SQL Server consists of two phases:
compilation and execution. This setting is useful for having SQL Server
validate the syntax and object names in Transact-SQL code when executing. It
is also useful for debugging statements that would usually be part of a
larger batch of statements"

Mike,
NOEXEC doesn't seem to work for me. For some reason, it doesn't detect
the drop of the table in my example. However, when I tried using SET
FMTONLY ON, it worked and does not depend on any branching in the
procedure itself that would prevent access to the underlying missing
table.
create table abc123 (co1l int)
go
drop proc abc123test
go
create proc abc123test @.b bit
as
begin
if @.b = 0
Select co1l from abc123
else
Select id from sysobjects
end
go
exec abc123test 1
exec abc123test 0
drop table abc123
go
set fmtonly on
exec abc123test 1
exec abc123test 0
set fmtonly off
drop proc abc123test
go

Is it possible to perform the checking at the time the stored procedure is
created. The problem I have got is that it would take a long time to test a
thousand+ number of stored procedures using exec, supplying different
parameters to each one etc. So I thought it would be easier to generate a
script that attempts to drop and then recreate the stored procedures and
stop when it fails because the table does not exist.
So is it possible to perform the check when I actually do the CREATE PROC...
create proc abc123test @.b bit
as
Select co1l from abc123
go
Thanks,
Chris

No. You can't do that at creation time. You could probably write
something pretty quickly to iterate through the syscolumns table for
each procedure and generate a dummy set of parameters. There is also
likely sample code out there to do the same.

Ok. I whipped something together that you can use directly in a T-SQL
script. The script is mildly tested, so additional testing is required
at your end before using on a production system. The script creates the
necessary dynamic SQL to execute each procedure with NULL parameters and
then executes using SET FMTONLY ON and stored the results of the
execution in the temp table.
Good luck.
-- Stores the objects, execution SQL, and result
Create Table #ExecProcs (
ID INT IDENTITY NOT NULL,
Owner nvarchar(128) NOT NULL,
SPName nvarchar(128) NOT NULL,
ParameterCount INT NOT NULL,
ExecResult INT NULL,
ExecSQL nvarchar(2000) NOT NULL,
PRIMARY KEY (ID))
go
-- Get a list of procedures and create the execution SQL
Insert into #ExecProcs (
Owner,
SPName,
ParameterCount,
ExecSQL )
Select
USER_NAME(o.uid) as "Owner",
o.name as "SPName",
COUNT(p.name) as "ParameterCount",
'SET FMTONLY ON;' +
'EXEC [' +
USER_NAME(o.uid) + '].[' + o.name + '] ' +
CASE SIGN(COUNT(p.name))
WHEN 0
THEN ''
WHEN 1
THEN
REPLICATE('NULL,', COUNT(p.name) - 1) +
REPLICATE('NULL', COUNT(p.name) - (COUNT(p.name) - 1))
END + ';'
from

o.id = p.id
where
o.type = 'P'
Group By

go

destination table not exist while adding column in published artic

I used the add_relpcolumn to add column in the published table but not
knowing that the subscriber database does not have the table. I found the
error on the distribution agent about 'Not able to alter the table because
the table doesn't exist', which explained what happened. As a result, it
breaks the replication. How do I fix the problem to make the replication
going again?
Thanks for any help in advanced
This sounds like a bug, could you post your publication script?
