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

Good Afternoon.
I am trying to write a short application within which I would like to embed a SQL Server Express database, all of which would be deployed via ClickOnce through a web site. The installation process seems to be working without trouble, including installation of the .NET Framework 2.0 and SQL Server Express 2005.
When the application launches on the new machine, however, I get a big Microsoft .NET Framework "Unhandled exception" error dialog box that indicates the database already exists and that the database file could not be attached. I am working with a clean virtual machine that I know has never had the database installed on it.
I fear I am overlooking something quite straightforward, but since this is the first time I have ever attempted to build a data-bound application, I am not sure where I am going wrong.
Perhaps the source of the problem, or a related problem, might be revealed even when I run the application in debug mode from within Visual Studio. I can run the application once, but if I try to run it again, I get an error when I try to open the database connection that is similar in content (database already exists...could not attach). I can run the SSEUtil and detach the database and then run the application again in debug mode and it works no problem (the first time!).
Lastly, if I install the application on the machine on which it was developed and make sure the database is detached, it will run without any trouble (even repeatedly). But, on a new blank machine, there is no database listed that matches my database name, so I cannot try to detach anything!?
My apologies for such a novice question!

Why is using an embedded SELECT statement faster than using an embedded UDF that has the same exact SQL code within?
Example (not syntax corrected)
Ex1:
SELECT myValue1, myValue2 FROM myTable WHERE aValue = (SELECT Value FROM someTable WHERE myIndex = 800)
is much faster than something like
Ex2:
SELECT myValue1, myValue2 FROM myTable WHERE aValue = (dbo.FN_myUDF(@vmyIndex))
Given that dbo.FN_myUDF has the same code as the embedded select in the first example.
TIA,

What I'd like to do is use the result of one query as the input foranother. eg:INSERT INTO foo VALUES ((SELECT id FROM people WHERE name = "bar"),10,'foobar') WHEREid = 1;Problem is, MSSQL wants a scalar value. Is there a way around this?Can someone tell me the correct syntax for what I want to do, or is thissomething that will have to be done outside SQL?Err. Hope I've been clear. Thanks for any help you folks can give.

I need to check the value of a column being pulled from an embedded select in the WHERE clause of a script but can't figure out how to do it. The script looks like this:
SELECT
LIST_ID,
NAME,
ADDRESS
(SELECT ANSWER FROM VALID_ANSWER WHERE VALID_ANSWER.LIST_ID = VIEW_LIST.LIST_ID) AS ANSWER
FROM VIEW_LIST
WHERE ANSWER = 'No'
The syntax above works in Oracle but in SQL Server I receive the following error: "Invalid column name 'OHIP'."

This is part of a query I have. I want to display the diagnosis code attached to a patient. Sometimes there are more than one which is why I have tried distinct. I am getting the message 'subquery returned more than 1 value...'
If I use MIN or MAX, its giving me the min possible diagnosis code alphabetically or the max, not the one actually assigned to the patient which is what I want.
(SELECT DISTINCT (Diagnosis.DiagnosisCode) FROM Diagnosis
LEFT OUTER JOIN CourseDiagnosis ON CourseDiagnosis.DiagnosisSer = Diagnosis.DiagnosisSer
LEFT JOIN Course ON Course.CourseSer = CourseDiagnosis.CourseSer
JOIN Patient ON Patient.PatientSer = Course.PatientSer
WHERE Diagnosis.ObjectStatus = 'Active' AND
Diagnosis.Description not like 'ERROR%' AND
Diagnosis.DiagnosisTableName not in ('RTDS Dates')),

I have a table that has the following fields:tblECHECKID (autonumber identity column)PTIDBatchnumPageDataPointDPValueThere are many other tables on which I run a script that tests to makesure the data meets certain entry requirements (I don't want to putrestrictions on the forms because the data entry personel have toenter what is on the survey).Anything that fails is copied to the tblECHECK table. All the datacopied into the table are identified by a batchnumer (batchnum).I want to write a script that will look at all the records in thetblECHECK table, and delete any duplicates (the batch numbers are theonly fields that would be different).I have tried the following with no success (it returns 0 records):Select *From tblECHECKWhere batchnum ='batch8' and not exists (select * from tblECHECK wherebatchnum = 'batch7')Any help would be appreciated.

IF( NOT( EXISTS( SELECT 1 FROM updatetable WHERE ScriptName = 'MY_Scripts' )))
RAISERROR('script_dateupdates is required prior to running this script.', 30,1);
This is the Exists statment on the top. I was trying to find out what does it read. Can someone reat that for me.
Also why Not is before the brackets why it is not like If NOT EXISTS (Select....... ) acutally this is my concern to find out.

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?

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

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 = "/".

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.

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.

insert into testing values ('2014-05-19 00:00:00.000', 10)
insert into testing values ('2014-08-15 00:00:00.000', 20)
insert into testing values ('2014-11-20 00:00:00.000', 30)

I'm looking into a problem a friend is having, and I'll say right offthe bat that I work with with php and MySQL, and not MS SQL.What he is attempting to do (in MS SQL) is take two database fieldsfrom a table (string fields), multiply them together, and put them intoa third field. This third column in the table has not yet been createdthe time of running the query.If it needs to be multiple queries, that is fine. My first thought isto use a simple ALTER query to add the column to the table, then tocall a UPDATE function which uses a select statement inside of it. I'mnot sure if something like this can even be done.// ------------ Suggested queryUPDATE chrisslu SET 'discquantity' = '(SELECTchrisslu.quantity*chrisslu.nr_of_discFROM chrissluWHERE (str(period,6)>=? AND str(period,6)<=?))' WHERE(str(period,6)>=?Andstr(period,6)<=?)// ------------ End Suggested queryIt starts with an UPDATE, but replaces the value to be set with aSELECT statement. I honestly don't even think this query issyntactically correct, I'm just trying to get the general concept down:).So, question the first: Is this type of query possible? The reasonI'm doing this is because I was told MS SQL has no way of storingtemporary variables... otherwise I would just call a SELECT statement,store the variable, and UPDATE the new field from the variable afterthe ALTER statement.Second question: If it is possible, am I on the right track, or doesit need to be entered in completely different than what I have?Third: Regarding the 'type'. Do I need to do any kind of typecastingor conversion of the fields? Both chrisslu.quantity andchrisslu.nr_of_disc are string fields (that is what I was told, theymay be varchar of some kind). In order to use them in a mathstatement, do they have to be floats, or doubles, or something similar?I appreciate any response, I know this was a long winded question.Chris

Hi there!
I've an embedded image (logo) in my report, and in the preview it looks wonderful, but after deploy the logo doesnt appear in the report (report server).
The url of the dead-link-image is http://hamsql1/Reports$BI/Reserved.ReportViewerWebControl.axd?.
I thought that an embedded image is stored "in" the report, but it seems to be an other place. Is it nessecary to deploy an embedded image too? Is it a problem of permissions (i read it in another threat)? How to set these image-see-permission? Or is there an other problem?
Every idea is very welcome!

Hi,
I am trying to find something like a light version of SQL Server 2k to store data for an application that will be distributed through a cd.
Since we also have a web front end for this application when the user is online, we prefer that we can reuse the code for connection on both the cd and the web.
Any idea what will work?
I have come accross MSDE 2k but was not able to find any documentation on the pros and cons for this product regarding its capacity, the type of data it can handle, security, ...
Please give me some pointer.
Thanks very much.
Baoha.

We have text files that are comma delimited, use double quotes as text qualifiers and sometimes have embedded double quotes. The embedded double quotes are escaped with an additional double quote like: below.
"123","product q"
"124","product ""a"""
DTS 2000 had no problem with this- it correctly parsed the files. The 2005 SSIS file connection manager correctly parses this in preview mode. But when the task is executed the task fails with the message "The column delimiter for column X was not found".
What is the recommended approach for this - we have alot of files in this format.
thanks

Every time I set the location of the textbox, it is behaving strangely by rendering at one location one time and changing location next time when it is rendered. I am viewing it in PDF format.
How can I fix the location of textboxes that renders at one location all the time ?

Hi,
documentation states, that Windows XP Embedded (XPe) is not supported by any SQL Server 2005 Edition (as I intend to use the Epress Edition on that platform, I post to this forum).
So, why is that? Is it just not tested or are there technical reasons for it? What are these reasons? What works and what doesn't on XPe? May XPe be supported in any later version?
thanks,

I am building a mobil application using Windows XP embedded. I need a database that will run on xp embedded as follows:
Client mode: Sometimes connected to server(local) sometimes disconnected.
Server Mode: Ready access to database from client and system running server.
Client must be able to switch to server mode in event of failure.
Does SQL Mobile support running Windows XP embedded on the Server?
Does SQL Mobile support running Windows XP embedded on the Client?
Does SQL Mobile support running Windows XP embedded in a failover mode?
If it does not support this type of operation then what mobile database will support XP Embedded in all modes stated above?
