Hello
How do you check if a column exist ?
for a table :
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[myTable]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[myTable]
GO
but I dont find it for a column
Thank you

Hey all - got a problem that seems like it would be simple (and probably is : )
I'm importing a csv file into a SQL 2005 table and would like to add 2 columns that exist in the table but not in the csv file. I need these 2 columns to contain the current month and year (columns are named CM and CY respectively). How do I go about adding this data to each row during the transformation? A derived column task? Script task? None of these seem to be able to do this for me.
Here's a portion of the transformation script I was using to accomplish this when we were using SQL 2000 DTS jobs:
'**********************************************************************
' Visual Basic Transformation Script
'************************************************************************
' Copy each source column to the destination column
Function Main()
DTSDestination("CM") = Month(Now)
DTSDestination("CY") = Year(Now)
DTSDestination("Comments") = DTSSource("Col031")
DTSDestination("Manufacturer") = DTSSource("Col030")
DTSDestination("Model") = DTSSource("Col029")
DTSDestination("Last Check-in Date") = DTSSource("Col028")
Main = DTSTransformStat_OK
End Function
***********************************************************
Hopefully this question isnt answered somewhere else, but I did a quick search and came up with nothing. I've actually tried to utilize the script component and the "Row" object, but the only properties I'm given with that are the ones from the source data.
thanks in advance!

Well, actually, as in the title. I have a table. The script should add a column if that column doesn't exist already. I use VB to combine the two queries. So what I want:
Query1: Does the column exists:
if No,
query2: create the column
How can I achieve this?
Hi
Can anybody tell me how can I find whether a column exists in my table or not???

How 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,
Dan
i need to check that the column exist in the table if yes the update/insert value in the column else i need to add the new column like new browser name in the table.

I am trying
IF OBJECT_ID(''tempdb..#tempTable.Column'') IS NOT NULL
But its returning me a null every time. Is there any other way to check if column exists in temporary table.
I'm trying to write a script that would only update a column if it exists.
This is what I tried first:
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Enrollment' AND COLUMN_NAME = 'nosuchfield')
BEGIN
UPDATE dbo.Enrollment SET nosuchfield='666'
END
And got the following error:
Server: Msg 207, Level 16, State 1, Line 1
Invalid column name 'nosuchfield'.
I'm curious why MS-SQL would do syntax checking in this case. I've used this type of check with ALTER TABLE ADD COLUMN commands before and it worked perfectly fine.
The only way I can think of to get around this is with:
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Enrollment' AND COLUMN_NAME = 'nosuchfield')
BEGIN
declare @sql nvarchar(100)
SET @sql = N'UPDATE dbo.Enrollment SET nosuchfield=''666'''
execute sp_executesql @sql
END
which looks a bit awkward. Is there a better way to accomplish this?
I've been looking around for some kind of known issue or something, but can't find anything. Here's what I'm experiencing:
I have a table with about 50,000 rows. I open several connections and use a command to ExecuteResultSet against each command, with CommandType.TableDirect, CommandText set to the name of the table, and IndexName set to various indexes. In the end, I have several SqlCeResultSet instances which are then maintained for the life of the AppDomain.
In a loop, I call SqlCeResultSet.Read() on one of the instances, and if it returns false, I call SqlCeResultSet.ReadFirst() - essentially creating a circular pass through the result set.
In a Visual Studio debug session, this approach goes swimmingly for a short time, and then after a successful Read(), I'm pegged with an InvalidOperationException (text: "No data exists for the row/column") for a column which was succesfully read on the previous Read(). If, in the immediate window, I call SqlCeResultSet.Read() again on the result set instance, the Get___ methods work as they had been in the previous reads.
It seems like the internal state of the ResultSet is getting corrupted somehow, but it is opaque to me. Any insights on why this suddenly throws this exception?
When I execute the below queries it works perfectly where as my expectation is, it should break.
Select * from ChildDepartment C where C.ParentId IN (Select Id from TestDepartment where DeptId = 1)
In TestDepartment table, I do not have ID column. However the select in sub query works as ID column exists in ChildDepartment. If I do change the query to something below then definately it will break -
Select * from ChildDepartment C where C.ParentId IN (Select D.Id from TestDepartment D where D.DeptId = 1)
Shouldn't the default behavior be otherwise? It should throw error if column doesnt exists in sub query table and force me to define the correct source table or alias name.
create table TestDepartment
(
DeptId int identity(1,1) primary key,
name varchar(50)
)
create table ChildDepartment
(
Id int identity(1,1) primary key,
[Code] ....

This is on Sybase but I'm guessing that the same situation would happen on SQL Server. (Please confirm if you know).
I'm looking at these new databases and I'm seeing code similar to this all over the place:
if not exists (select 1 from dbo.t1 where f1 = @p1)
begin
select @errno = @errno | 1
end
There's a unique clustered in dex on t1.f1.
The execution plan shows this for this statement:
FROM TABLE
dbo.t1
EXISTS TABLE : nested iteration.
Table Scan.
Forward scan.
Positioning at start of table.
It's not using my index!!!!!
It seems to be the case with EXISTS statements. Can anybody confirm?
I also hinted to use the index but it still didn't use it.
If the existence check really doesn't use the index, what's a good code alternative to this check?
I did this and it's working great but I wonder if there's a better alternative. I don't really like doing the SET ROWCOUNT 1 and then SET ROWCOUNT 0 thing. SELECT TOP 1 won't work on Sybase, :-(.
SET ROWCOUNT 1
SELECT @cnt = (SELECT 1 FROM dbo.t1 (index ix01)
WHERE f1 = @p1
)
SET ROWCOUNT 0
Appreciate your help.
Hello,
I am trying to create a table if one with the same name does not exists. My code is:
Dim connectionString As String = "Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|PensionDistrict4.mdf;Integrated Security=True;User Instance=True"
Dim sqlConnection As SqlConnection = New SqlConnection(connectionString)
Dim newTable As String = "CREATE TABLE [" + titleString + "Comments" + "] (ID int NOT NULL PRIMARY KEY IDENTITY, Title varchar(100) NOT NULL, Name varchar(100) NOT NULL, Comment varchar(MAX) NOT NULL, Date datetime NOT NULL)"
sqlConnection.Open()
Dim sqlExists As String = "IF EXISTS (SELECT * FROM PensionDistrict4 WHERE name = '" + titleString + "Comments" + "')"
Dim sqlCommand As New SqlCommand(newTable, sqlConnection)
If sqlExists = True Then
sqlCommand.Cancel()
Else
sqlCommand.ExecuteNonQuery()
sqlConnection.Close()
End If
I keep getting a "Input String was incorrect format" for sqlExists? I am new to Transact-SQL statements, any help would be appreciated.

ok i have 2 tables---one table is name CourseInformation with a field named Instructor and the data in there looks like this 'John Doe'.
My other table Instructors has 3 fields InstructorName, LastName, FirstName.
I am grabbing the Instructor field from CourseInformation and breaking up the names and inserting them into my instructors table as follows..
Insert into Instructors(InstructorName, LastName, FirstName)
(Select Distinct
ltrim(SUBSTRING(Instructor,CHARINDEX(' ',Instructor)+1,len(Instructor)))+', '+
SUBSTRING(Instructor,1,CHARINDEX(' ',Instructor)-1),
ltrim(SUBSTRING(Instructor,CHARINDEX(' ',Instructor)+1,len(Instructor))) as LName,
SUBSTRING(Instructor,1,CHARINDEX(' ',Instructor)-1) as FNamefrom CourseInformation
where NOT EXISTS(Select * from instructors where LastName = LName and FirstName = FName)
AND Instructor is not null)
Only problem is, I cant get the where not exists clause to work right(of course that wont work what i have cuz the LName and FName columns dont exist, i just did that for demo purposes). I dont want duplicate instructors in there..how can i accomplish this..is there a better way to rewrite my query? Any help is appreciated.
HI All,Which is best among the two 1) NOT IN or 2) NOT EXISTS .If the query is Select col1 from tab1 where col2 NOT IN (Select col 3 from tab2 where cl3=0) OR Select col1 from tab1 where col2 NOT EXISTS (Select col 3 from tab2 where cl3=0)

Hi,
Is there any way to check whether a column is there in the table, if it is there i need to drop it through script.
i'm looking for the script, something like this..
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[FK_Tbl_Product_Tbl_Products]') and OBJECTPROPERTY(id, N'IsForeignKey') = 1)

hi guys! is there anyway to retrieve the row from the result of EXISTS function aside from using the code below?

I'm trying to search my table for a url, and if it in the table, increment the number of hits of the url. Here's my code:
tblLinks

AS
IF EXISTS(SELECT LinkURL

WHERE @url = LinkURL)

UPDATE tblLinks

I've also tried:

IF (SELECT LinkURL

WHERE @url = LinkURL) IS NOT NULL
BEGIN
UPDATE tblLinks
SET NumOfHits = NumOfHits + 1

Hi all,

Well, finally I lost one day to find a solution for a simple problem. I
wanted to derive two tables... that seemed to be simple... but it isn't.
My last question for today:
Why does my sql query return the error: Only one expression can be specified in the select list when the subquery is not introduced with EXISTS
The Query:
SELECT
Configurations.AlarmId, Configurations.Mode, Configurations.Activated,
Configurations.Empty, Configurations.UserName, Configurations.datetime,
(SELECT ConfigurationId, Setpoint1, Alarm
FROM
dbo.ExtendedValues(Configurations.ConfigurationId) AS ExtendedValues)
AS Expr1
FROM Configurations INNER JOIN
Controllers ON Configurations.ConfigurationId =
Controllers.ActiveConfig INNER JOIN
Tanques ON Controllers.ControllerId = Tanques.ControllerId
WHERE (Tanques.TanqueId = 1)
Where do I have to enter EXISTS?
Thanks for every hint!!
P.D.: The ExtendedValues Function:
CREATE FUNCTION dbo.ExtendedValues
(
@ConfigurationId int = -1
)
RETURNS TABLE
AS
RETURN SELECT *
FROM ConfigurationsTanques
WHERE ConfigurationsTanques.ConfigurationId = @ConfigurationId
