Check If Temporary Table Exists
Oct 5, 2006Hello.
How can I check if a temporary table exists in the current context?
With normal tables I'd do a
EXISTS ( SELECT name FROM sysobjects
WHERE name='myTableName' AND type='U')
However, I can't do that with a temporary table. I'd have to go look at the sysobjects table in the tempdb database.
The problem is that for temporary tables, a suffix is added to the name to make it unique for each scope. I can't change the WHERE clause to name LIKE 'myTableName%' because this would return true if a temporary table with the same name exists in a different scope.
Any ideas?

How To Check If A Temporary Table Exists?
Apr 29, 2008I apologize if this has been asked, and answered, before. I wasn't able to find relevant posts on the forum. A Google search pointed me to a couple of pages that offered this simple recipe:
if object_id('#temp') is not null
print 'table exists';
(I have also tried 'tempdb.#temp', and 'object_id(..,'U'))
Unfortunately, this doesn't work: the condition evaluates to 'false'. #temp is alive and well: strying to 'select .. into' it raises error
> There is already an object named '#temp' in the database.
Thanks a lot!
Is It Possible To Check If A Local Temporary Table Exists ?
Mar 10, 2008It is possible for global temporary tables, but for local, it is said that the names(in the tempdb) change each time the table is created, so i am not sure if there is a way to check it.
Thanks

How To: Check If A Column Exists, And If Not, Add It?

Query1: Does the column exists:
if No,
query2: create the column
How can I achieve this?
How To Check That Column Does Not Exists Before Adding It?
Jun 22, 2007How to check to make sure a column does not exist before adding it? Be nice to do this in t-sql code instead of using ado.net. It seems as if the IF NOT EXISTS is not supported in SqlCe 3.1? I am trying to do this but I get the token error:
IF NOT EXISTS (
select *
from Information_SCHEMA.columns
where Table_name='authors' and column_name='NewColumn'
)
select 'no'
Is there a list of all CE supported t-sql commands?
Thanks,

May 20, 2008Hi,
This my first time using the link server to read the files directly from within SQL2005, so issues the following link:-
EXEC sp_addlinkedserver
@server = N'MYVFPSERVER', -- Your linked server name here
@srvproduct=N'Visual FoxPro 9', -- can be anything
@provider=N'VFPOLEDB',
@datasrc=N'"C:PROGRAM FILESMICROSOFT VISUAL FOXPRO 9Samplesdata estdata.dbc"'
After that i can open query and do the import issues, but how can check if the table exists before issues the query.

How To Check If A Single Value Exists In A Table
Sep 14, 2006What’s the easiest way to check if a single value exists in a table column? I’m building a simple login page, and I want to get the username and check if it exists in my Users table. Here’s my SQL: SELECT UserID FROM UsersWHERE UserID = "admin" Could someone give me code to check for “admin” in my UserID column? Here’s some code I tried, using my SqlDataSource, but it returns an error “Could not load type 'System.Data.OleDb'” protected void Button1_Click(object sender, EventArgs e) { // Retreive the results from the SqlDataSource as a DataReader OleDbDataReader reader = (OleDbDataReader) SqlDataSource1.Select(DataSourceSelectArguments.Empty); // Read in the value if (reader.Read()) { } // Close the reader reader.Close(); } I don’t have to use the SqlDataSource, but originally thought it might be easier. I know how to use SqlDataSource to fill a whole GridView but this is different.

I want to create an SQL Function that checks if a table exists and returns true or false. I will pass this function a paramter (say @COMPANYID) e.g.

Check Access Table Exists From SSIS
Apr 17, 2007I am writing my first SSIS task. I have an MS Access database and I'm moving the contents of each table into a like-named SQL Server database. The task is working properly except for one step.
The source Access database may or may not have one of the tables in it. It will always have TableA, TableB, and TableC, but may or may not have TableD. I need to write my SSIS package in such a way that it will detect the presence/absence of TableD and either run or skip the import step for this table accordingly.
Can someone assist with the step that detects the table presence/absence in the MSAccess database?
thanks,

UDF As Computed Column In Temporary Table In Proc
Jun 16, 2008I've created a stored procedure that creates and uses a temporary table with a computed column. I want the computed column to call a user-defined function(UDF) that I've created. Here's an example:
CREATE PROCEDURE [dbo].[usp_Proc]
(
@Date datetime
)
AS
BEGIN
--Drop the temp table if it still exists so reports come out accurate
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[#temp]') AND type in (N'U'))
DROP TABLE #temp;
--Create the temp table for use in this stored procedure
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[#temp]') AND type in (N'U'))
CREATE TABLE #temp (
[ID] INT PRIMARY KEY IDENTITY(1,1),
[Column1] NVARCHAR (30) DEFAULT ('XXXX-XXXXX'),
[Column2] INT DEFAULT (0),
[Column3] INT DEFAULT (0),
[Column4] INT DEFAULT (0),
[Column5] as ([Column2] + [Column3] + [Column4]),
[Column6] as (dbo.FunctionName('5381', [Column1]))
)
--Insert data
INSERT INTO #temp([Column1], [Column2], [Column3], [Column4])
SELECT 'String', 1, 2, 3
--Perform more calculations
<snipped...>
SELECT * FROM #temp
DROP TABLE #temp
END
This is an example of the function:
CREATE FUNCTION [dbo].[FunctionName]
(
-- Add the parameters for the function here
@Type nvarchar(4),
@Quantity int
)
RETURNS Money
AS
BEGIN
RETURN (cast((SELECT ([Value] * cast(@Quantity as int)) FROM tblTable WHERE [ID] = @Type) as Money))
END
The error message I'm getting after I've created both the stored procedure and the UDF is when calling the stored procedure. Here it is:
Msg 4121, Level 16, State 1, Procedure usp_Proc, Line 13
Cannot find either column "dbo" or the user-defined function or aggregate "dbo.FunctionName", or the name is ambiguous.
There's no way the function name is ambiguous. Is it even possible to do what I'm trying to do or am I just calling it the wrong way?

Table/column Dependency Check
Dec 28, 2007Hi All,
We have a very convoluted ETL system which is pulling unnecessary data. First thought is to restrict everything so that only the columns/tables that are necessary are brought back. We have a tons of reporting stored procedures that depend on ETL tables, is there anyway we can find out which column/tables these stored procedures are using?
Thanks!

Check If Cursor Exists
May 11, 2004I declare a cusror named crInv inside a loop.
Since I open this cursor a lot of times I want to check if is already opened.
I try to use the Cursor_status function but it always returns -3.
The syntax is:
DECLARE crInv SCROL CURSOR FOR
SELECT Val1, Val2 FROM TABLE1 WHERE Val3=450
If Cursor_Status('local','crInv')>0 BEGIN
CLOSE crInv
DEALLOCATE crInv
END
This code is inside a loop.
If I PRINT Cursor_Status('local','crInv') before and after the DECLARE statement it always returns -3.
What is wrong??

Ok so that's simple, but how can I return a true or false if '1' is a value that exists in the db?
thanks.
