Select Where Not Exists

Jul 20, 2005

I have a table that has the following fields:

tblECHECK
ID (autonumber identity column)
PTID
Batchnum
Page
DataPoint
DPValue

There are many other tables on which I run a script that tests to make
sure the data meets certain entry requirements (I don't want to put
restrictions on the forms because the data entry personel have to
enter what is on the survey).

Anything that fails is copied to the tblECHECK table. All the data
copied into the table are identified by a batchnumer (batchnum).

I want to write a script that will look at all the records in the
tblECHECK table, and delete any duplicates (the batch numbers are the
only fields that would be different).

I have tried the following with no success (it returns 0 records):

Select *
From tblECHECK
Where batchnum ='batch8' and not exists (select * from tblECHECK where
batchnum = 'batch7')

Any help would be appreciated.

Embedded IF EXISTS(SELECT * ...) 1 ELSE 0

Jun 11, 2008

I have a Select statement that was working just fine:
string sSqlCmd = "INSERT INTO SiloKeywords (Silo_ID, Keyword, UserName) SELECT Silo_ID,'" + Keyword + "', '" + strUsername + "' FROM SiloNames WHERE Silo_Name = '" + Uri + "'";
the PM now wants to capture the internal User, which I have done but I am having real problems with the syntax if the internal User exists:

string sSqlCmd = "INSERT INTO SiloKeywords (Silo_ID, Keyword, UserName, IsInternal) SELECT Silo_ID,'" + Keyword + "', '" + strUserName + "', if EXISTS(SELECT * FROM InternalUsersList WHERE Alias = '" + arrResult[1] + "') 1 ELSE 0 FROM SiloNames WHERE Silo_Name = '" + Uri + "'";
I am completely lost here.

Thanks for any help

Select/Where Exists Issues- Any Ideas?

Feb 27, 2007

I am trying to use the following statement/query to delete any rows in tblcntslist table where tblcntslist.Company2 = tblCompany.Name.

Basically I am trying to look in the tblCompany table, look at the 'name' column, see if there are any entries in there that match entries in the tblcntslist.Company2 column. If there are matches, I want to delete them from the tblcntslist table.

I already "massaged" both table columns and removed all special characters, spaces, and other meaningless info that could result in incorrect matching. This way it is a match based on pure letter/number strings. I even set all as UCase in both table columns.

Code:

Delete from tblcntslist
where exists
(select * from tblCompany INNER JOIN tblCompany
ON tblCompany.Name = tblcntslist.Company2
where tblCompany.Name = tblcntslist.Company2)

I am getting the following error:
Server: Msg 1013, Level 15, State 1, Line 4
Tables or functions 'tblCompany' and 'tblCompany' have the same exposed names. Use correlation names to distinguish them.

I am a bit confused as to why. Any ideas?

Trying To Select Info With If Exists Statement With No Avail

Jan 6, 2004

Im trying to select rows on the following criteria

My app has a user that can have x jobs, each job has related entries which are marked has unread or read. I need to return any jobs that contain any unread entries also I need to return other jobs that have no entries marked as read.

I am able to return the following:

Comment UnReadMy Job 164
Comment UnReadFor Cam 166

Comment ReadThe Job 157
Comment ReadThird 159
Comment ReadMy Job 164
On Site Visit ReadMy newest job for log test 167

but as you can see jobid 164 appears in both groups and I need it to be one or the other

I tried using the if exists statement and was only able to return one group either unread or read, not both. I've tried everything but I'm new and I figure that theres got to be a more elegant way. Heres my sql:

CREATE PROCEDURE spGetJobsByUnreadAndReadByUserID
@UserID INT
AS

BEGIN
IF EXISTS(SELECT DISTINCT Master_Jobs.JobID, Profiles.ProfileDescriptor, Backup_UserNotes.BackUp_Read, Master_Jobs.Job_Title, Master_Jobs.Contact,

Job_Assignments.UserID = Users.UserID

WHERE Users.UserID = @UserID AND-- Note.FK_UserID = User_Notes.FK_UN_UserID AND
BackUp_Read = 'UnRead'

ORDER BY BackUp_Read ASC
END

ELSE

BEGIN

SELECT DISTINCT Master_Jobs.JobID, Profiles.ProfileDescriptor, Backup_UserNotes.BackUp_Read, Master_Jobs.Job_Title, Master_Jobs.Contact,
Master_Jobs.Due_Date, Master_Jobs.Due_Time, Master_Jobs.Next_Action, Master_Jobs.By_Who

Transact SQL :: Select Unique From Table If Specific Value Does Not Exists

Jul 31, 2015

I have a table that has for each shop a value that can change over time.For example

BK_POS 1 --> Segment A
BK_POS 1 --> Segment /

What I would like to achieve is to get all distinct Shops (BK_POS) from the table above, but if for that specific pos a row exists where the segment = "/" then I do not want to take this BK_POS in my select query.More concrete, the for example above I do not want to select BK_POS 1 because he has one row where the segment = "/".

Transact SQL :: Case Statement In Where Clause - Select First / Default Value If Two Different Value Exists

Nov 16, 2015

I have scenario where i have to pick one particular value from where condition. Here is the example:A store can have different types i-e A or B , A and B or either A or B.

Store Type Sales
11 A 1000
23 A 1980
23 B 50
5 B 560

I want to filter the store in "where clause" where

1)- if the store has type A and B, then assign only A
2)- if the store has type A associated with it then assign A
3)- if the store has type B associated with it, then assign B.

Select Store, sum(sales), Type
from table1
where (TYPE]= (case when [TYPE] in ('A','B') then 'A'
when [TYPE]='A' then 'A' else 'B'end))
GROUP BY [store], [TYPE]

The above statement is not working for when store has only Type B associated with it.

Need To Set A Field In A Select Statement Equal To Yes Or No If Record Exists In Separate Table

Jan 8, 2008

Hey gang,
I've got a query and I'm really not sure how to get what I need. I've got a unix datasource that I've setup a linked server for on my SQL database so I'm using Select * From OpenQuery(DataSource, 'Query')
I am able to select all of the records from the first two tables that I need. The problem I'm having is the last step. I need a field in the select statement that is going to be a simple yes or no based off of if a customer number is present in a different table. The table that I need to look into can have up to 99 instances of the customer number. It's a "Note" table that stores a string, the customer number and the sequence number of the note. Obviously I don't want to do a straight join and query because I don't want to get 99 duplicates records in the query I'm already pulling.
Here's my current Query this works fine:
Select *From OpenQuery(UnixData, 'Select CPAREC.CustomerNo, CPBASC_All.CustorCompName, CPAREC.DateAdded, CPAREC.Terms, CPAREC.CreditLimit, CPAREC.PowerNum
From CPAREC Inner Join CPBASC_All on CPAREC.CustomerNo = CPBASC_All.CustomerNo
Where DateAdded >= #12/01/07# and DateAdded <= #12/31/07#')
What I need to add is one more column to the results of this query that will let me know if the Customer number is found in a "Notes" table. This table has 3 fields CustomerNo, SequenceNo, Note.
I don't want to join and select on customer number as the customer number maybe repeated as much as 99 times in the Notes table. I just need to know if a single instance of the customer number was found in that table so I can set a column in my select statement as NotesExist (Yes or No)
Any advice would be greatly appreciated.

IF NOT EXISTS (... - EXISTS TABLE : Nested Iteration. Table Scan.Forward Scan.

Sep 20, 2006

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.

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.

Where Not Exists---help

May 27, 2007

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.

IF EXISTS Help

Oct 31, 2007

Hi,
I'm having problems with this T-SQL:
Sorry if this is obvious, I'm very new to this...

Just trying to return the ID if the row exists and if not just return 0.
What would I need to turn this into a stored procedure too?

Code Block

declare @Return int

if exists(select id from Computer where Computer_name = 'MYCOMPUTER')
begin
select @Return = id
PRINT @Return
end
else
begin
select @Return = 0
PRINT @Return
end

I'm getting this error....

Msg 207, Level 16, State 1, Line 5Invalid column name 'id'.Msg 207, Level 16, State 1, Line 10Invalid column name 'id'.

NOT IN, NOT EXISTS

Mar 10, 2008

I'm running into a problem on my SQL2000 server. I thought all 3 of the following queries SHOULD return the same results, but the query using the NOT IN does not return any records where the other 2 queries DO.

Is my understanding of NOT IN wrong, or is there something corrupt in my DB?

SELECT *
FROM [person]
WHERE personid NOT IN (SELECT personid FROM [personOrganization])

SELECT *
FROM [person]
LEFT OUTER JOIN [personOrganization]
ON [Person].[personId] = [personOrganization].[personId]
WHERE [personOrganization].personid IS NULL

SELECT *
FROM person
WHERE NOT EXISTS(SELECT 1 FROM [personOrganization] WHERE [personOrganization].personid=person.personid)
