I want to enter a website address into a TextBox and on AutoPostBack check to see if the entry is LIKE any in a SQL 2000 database tblLinkAddresses. If it is not - add it to the table and if it is display the LIKE matches.
Where do I start?
Hi,
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)
ALTER TABLE [dbo].[Tbl_Product] DROP CONSTRAINT FK_Tbl_Product_Tbl_Products

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
-----------------------
URL | NumOfHits

ALTER PROCEDURE sproc_UpdateLink

@url varchar
)
AS
IF EXISTS(SELECT LinkURL
FROM tblLinks
WHERE @url = LinkURL)
BEGIN
UPDATE tblLinks
SET NumOfHits = NumOfHits + 1
WHERE @url = LinkURL
END
RETURN
I've also tried:
ALTER PROCEDURE sproc_UpdateLink

AS
IF (SELECT LinkURL
FROM tblLinks
WHERE @url = LinkURL) IS NOT NULL
BEGIN
UPDATE tblLinks
SET NumOfHits = NumOfHits + 1
WHERE @url = LinkURL
END
RETURN
but that didn't work either.

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

I'm trying to enable checking for completion of a set of tasks the first of which is the creation of a table via a user procedure up_UpdateHFOTable.
If that fails I want to exit my master_proc and return a message to that effect.
My master_proc has the following code...

set @error_msg =

Cannot add rows to sysdepends for the current stored procedure because it depends on the missing object 'up_UpdateHFOTable'. The stored procedure will still be created.
Then when I run my master_proc I'm getting...
Could not find stored procedure 'up_UpdateHFOTable'.

I am going to use the BCP utility to export data from a table in a SQL Server 2000 database to .csv file, but I must determine if the file already exists. The BCP export code it going to be in a stored procedure and will be configured to run every two hours so I must have a way of checking if the file exists prior to executing the BCP instruction. If the file exists then no big deal just abort and two hours later it will try again, at some point the file will not exist and the export will export all the data since the last export - but normally this will happen every two hours; I just need to make sure that the "other peoples" utility has proccessed the file (and by definition deleted it).
It makes me no difference whether the best way to do this would be using a batch file that execute and returns true/false or a VBScript or if there really is a way to do it in TSQL. I just cannot seem to find any way.
I have two tables that I have to compare:
Code:
Table:PR

123-456 2000 02
567-890 2000 01
567-890 2000 02

1000 00
1000 01
1000 02
2000 00

After Insert I should have:
wbs1 wbs2 wbs3
123-456 1000 00
123-456 1000 01

Basically, I need to insert the wbs2 and wbs3 where it does not exist in each wbs1.
What I have now will find the values that need to be inserted for a particular project but I don't know how to go through each project and perform the insert:

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
