Can Iif Be Used To Change Query Result?
Apr 10, 2007
I'm converting a set of queries from Access to work as stored procedures on SQL server, and one of them that uses IIF gives me a syntax error. Here's the WHERE clause of the SELECT:
WHERE IIF(@myExtNum > 0,D.ExtentionNumber=@myExtNum,'') AND ...
I get the error message "syntax error near '>'."
It would seem this query wants to do two things: 1) if @myExtNum is >0, return only the rows for which D.ExtentionNumber equals a user specified value, or 2) if @myExtNum is 0 ignore this part of the condition.
I can rewrite this using multiple ANDs and ORs, but I wodered if there was a way I could get IIF working.
Something in my gut tells me this is not going to work, that IIF is being used to modify the query; that is, change which rows are returned; it is not being used to change how a given data value is displayed, which I think was the purpose for which IIF was originally intended.
Does anyone have an insight on this?

As the topic suggests I need the end results to show a list of shows and their dates ordered by date DESC.
Tables I have are structured as follows:
SHOWS
showID
showTitle
SHOWACCESS
showID
remoteID
VIDEOS
videoDate
showID
SQL is as follows:
SELECT shows.showID AS showID, shows.showTitle AS showTitle,
(SELECT MAX(videos.videoFilmDate) AS vidDate FROM videos WHERE videos.showID = shows.showID)
FROM shows, showAccess
WHERE shows.showID = showAccess.showID
AND showAccess.remoteID=21
ORDER BY vidDate DESC;
I had it ordering by showTitle and it worked fine, but I need it to order by vidDate.
Can anyone shed some light on where I am going wrong?
thanks

Example:
Select StoreId from tblStores
S1
S2
S3
S4
I want to display a more friendly name. I have been using a case statement:
select case
WHEN storeId = 'S1' THEN 'NY Store'
WHEN storeId = 'S2' THEN 'CA Store'
...
end AS StoreName
If I am doing a simple 1:1 mapping like that, is there a better way than using a case statement (without creating/modifying tables)?

Is there a way of taking a result from a query and pulling out a certain account number and displaying those account numbers - as fred? Eg. I have a drop down of account number (s) however they pull from a table that only displays them as account numbers. I would like to give more a description to certain account numbers that are pulled. Eg. account number 234 will be fred and account number 555 will be sam etc. Trying to add it to the query on the dataset is complicated, so I was wondering if I created an additional blank field with an expression to be able to do this?

I am interested in changing the way that data is displayed in my result set.Essentially I want to display a selection of rows (1 to n) as columns, the following diagram explains my intentions.Perhaps one of the greatest challenges here is the fact that I do not have a concrete number of rows (or BIN numbers). Each stock item could be stored in one or more BINS, which I will not know until running my query.

I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w. one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included) INSERT INTO @users SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is: SELECT u.userName,u.userID
FROM tableU u
LEFT JOIN tableW w ON w.workgroupID = u.workgroupID
WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!

I hope I am not asking about something that has been done before, but Ihave searched and cannot find an answer. What I am trying to do is torun a query, and then perform some logic on the rowcount and thenpossibly display the result of the query. I know it can be done withADO, but I need to do it in Query Analyzer. The query looks like this:select Varfrom DBwhere SomeCriteriaif @@Rowcount = 0select 'n/a'else if @@Rowcount = 1select -- this is the part where I need to redisplay the resultfrom the above queryelse if @@Rowcount > 1-- do something elseThe reason that I want to do it without re-running the query is that Iwant to minimize impact on the DB, and the reason that I can't useanother program is that I do not have a develpment environment where Ineed to run the queries. I would select the data into a temp table, butagain, I am concerned about impacting the DB. Any suggestions would begreatly appreciated. I am really hoping there is something as simple as@@resultset, or something to that effect.

I have a column colC in a table myTable that has a value (e.g. '0X'). The position of a non-zero character in column colC refers to the ordinal position of another column in the table myTable (in the aforementioned example, colB).
To get a column name (i.e., colA or colB) from table myTable, I can join ("ON cte.pos = cn.ORDINAL_POSITION") to INFORMATION_SCHEMA.COLUMNS for that table catalog, schema and name. But I want to show the value of what is in that column (e.g., 'ABC'), not just the name. Hoping for:
COLUMN_NAME Value
----------- -----
colB 123
colA XYZ
I've tried dynamic SQL to no success, probably not executing the concept correctly...
Below is what I have:
CREATE TABLE myTable (colA VARCHAR(3), colB VARCHAR(3), colC VARCHAR(3))
INSERT INTO myTable (colA, colB, colC) VALUES ('ABC', '123', '0X')
INSERT INTO myTable (colA, colB, colC) VALUES ('XYZ', '789', 'X0')
;WITH cte AS
(
SELECT CAST(PATINDEX('%[^0]%', colC) AS SMALLINT) pos, STUFF(colC, 1, PATINDEX('%[^0]%', colC), '') colC
[Code] ....

I'm having a bit of a trouble explaining what I'm trying to do here.
I have 3 "source" tables and a "connecting" table that I'm going to use
tblContacts - with contactID, ContactName etc
tblGroups - with GroupID, GroupName
tblSubGroups - with SubGroupID, GroupID and SubGroupName (groupID is the ID for the parent Group from tblGroups)
They are related in a table called
tblContactsGroupConnection - with ContactID, GroupID and SubGroupID
One contact can be related to many subgroups.
What I want is a list of all contacts, with their IDs, names and what groups they are related to:
ContactID, ContactName, [SubGroupName1, SubGroupName2, SubGroupName3]
ContactID, ContactName, [SubGroupName1, SubGroupName3]
ContactID, ContactName, [SubGroupName3]
I'm sure there's a simple solution to this, but I can't find it. Any help appreciated. :)

Hi,
Please help me with an SQL Query that fetches all the records from the three tables but a unique record for each forum and topicid with the maximum lastpostdate. I have to bind the result to a GridView.Please provide separate solutions for SqlServer2000/2005.
I have three tables namely – Forums,Topics and Threads in SQL Server2000 (scripts for table creation and insertion of test data given at the end). Now, I have formulated a query as below :-
SELECT ALL f.forumid,t.topicid,t.name,th.author,th.lastpostdate,(select count(threadid) from threads where topicid=t.topicid) as NoOfThreads
FROM
Forums f FULL JOIN Topics t ON f.forumid=t.forumid
FULL JOIN Threads th ON t.topicid=th.topicid
GROUP BY t.topicid,f.forumid,t.name,th.author,th.lastpostdate
ORDER BY t.topicid ASC,th.lastpostdate DESC
Whose result set is as below:-
forumid
topicid
name
author
lastpostdate
NoOfThreads

Hi,all,
I ran the two queries and I thought it would be the same, but it's different.
Can you explain to me.
Query 1: result---52 rows
select s.InsuredSurname, s.email from studyUSA s
join interMedical I on s.email=I.email
where convert(char(10), s.enrolldate, 126)>= '2004-01-01'
and convert(char(10), s.enrolldate, 126) <='2005-05-20'
and (s.agentcode not like '162%') and (s.agentcode not like '17%')
and s.agentcode <> '130844'
Query 2: result--14 rows
select s.InsuredSurname, s.email from tis_studyUSA s
where convert(char(10), s.enrolldate, 126)>= '2004-01-01'
and convert(char(10), s.enrolldate, 126) <='2005-05-20'
and s.email IN (Select I.Email from tis_InterMedical I)
and (agentcode not like '162%') and (agentcode not like '17%')
and agentcode <> '130844'

hi,
i've tried searching on this but not having much luck, i'm trying to use the result of one and use it in another. is there any way to do this?
So for example, i would use the result of this query and store it in a variable called @tmp_id (if possible)
SELECT TOP 1 ID FROM tblWines WHERE RefNo LIKE 'AB1234';
then use that variable in another query
INSERT INTO tblLogWines (WineID, Date) VALUES (@tmp_id, now());
i've simplied the context to make it a little more understandable, any help is appreciated.

Hello all,I tryed to simplify the problem as much as possible. I'll start with theDDL:----------------------------------CREATE TABLE #MyTable(NoID INT,Type CHAR,DateTransaction DATETIME)INSERT INTO #MyTable (NoID, Type, DateTransaction)SELECT 1 AS NoID, 'A' AS Type, '2004-01-01' AS DateTransaction UNION ALLSELECT 2, 'C', '2004-01-01' UNION ALLSELECT 3, 'B', '2004-01-01' UNION ALLSELECT 4, 'C', '2004-01-02' UNION ALLSELECT 5, 'B', '2004-01-02' UNION ALLSELECT 6, 'C', '2004-01-02' UNION ALLSELECT 7, 'A', '2004-01-03' UNION ALLSELECT 8, 'B', '2004-01-03' UNION ALLSELECT 9, 'A', '2004-01-03' UNION ALLSELECT 10, 'C', '2004-01-03' UNION ALLSELECT 11, 'B', '2004-01-03'----------------------------------What I want is all the same Type which, for a same DateTransaction, as adifferent Type inserte beetween them when data is sorted by DateTransactionand NoID. In this case I would like:Type DateTransaction------ -----------------C 2004-01-02 /* B is between two C (NoID = 5) */A 2004-01-03 /* B is between tow A (NoID = 8) */B 2004-01-03 /* A and C are between two B (NoID = 9 and10) */All of these have for the corresponding date at least one transaction with adifferent type between.In the real situation NoID is an autoincrement field, the PK. And theDateTransaction hasn't any time, just a round date.Any suggestion?Thanks for your time.Yannick

Basically, I track complaints and each complaint can have 1 or more subjects associated with it.
The structure is the complaint is referenced in a complaintsubject row and I use the persons table to find out detail of the complaintsubject (firstname, middlename, lastname) complaintsubject just holds Id's to normalize the database rather than have all details of persons table copied into every complaint (pretty basic so far).
My first question is regarding structure...since my complaint to complaintsubject relationship is 1 to many I assume the best way to associate the two is to have a FileNumber field in the complaintsubject linking back to a complaint. Is there any other design that is better suited to this type of relationship?
Second question and most important: I need a way to search by a string that appears in any part of the firstname, middlenames, lastname. I have the query for this and its working. But the problem arises when I have more than one match (i.e. 2 or more people are involved in the complaint where the match string fits both - example say we have a match string of 'an' and in complaint xyz 2 people involved are Sandy Blah and Andy Blue). Now when I do my join to pull out the complaints that involve any people with a name containing 'an' the result set returns the same complaint twice, one for Sandy Blah and the other for Andy Blue). Since I am only interested in certain complaint details and not interested in having the actual people involved returned in the result set, I would like to return only 1 row for each complaint when more than one match is found for the firstname,middlenames,lastname. I could live with having the duplicate rows and process them easily application side, but I am sending a lot of duplicate information over the wire for nothing and would like to optimize this.
I hope I have described this well enough and would greatly, greatly appreciate any help you can provide.
Best Regards.

MS SQL Server 2000 SP3
I'm not the most knowledgable DBA, I've had to learn almost completely on my own, AND on a production server, because it's the only MS SQL Server I have access to.
Everything was fine before I took down the production server for maintenance. Someone suggested that I re-index my tables because I was having some performance issues with a particularly large table (it didn't help that table btw), so I did re-index.
Now, Everything works wonderfully, except for the performance issue mentioned AND one other thing that is going horribly wrong.
Here is the table:
create table ABMcontactlink
(
classifier varchar(20) not null, /* Classification of contact. */
transmitter varchar(36) not null,
contact integer not null, /* Link to ABMcontact (detail) table */
primary key (classifier,transmitter,contact),
foreign key (contact) references ABMcontacts(identifier),
group_name varchar(20) null,
priority smallint null, /* Authorization level. */
type smallint null, /* Autoalarm or Manual */
last_modification_date datetime, /* Date/time record last touched */
last_modification_id varchar(40) /* Who last touched record */
)
go
create index IndexABMcontactlink on
ABMcontactlink(classifier,transmitter)
go
create index CandidateABMcontactlink on
ABMcontactlink(transmitter)
go
As you can see, I have the primary key, which creates a clustered index, PK_ABMContactlink_Some Number, and two other indexes.
Now, this is a very busy production database, and most quick short queries benefit more from CandidateABMContactlink than from the other two indexes.
Unfortunately, in this production system, and this table, seconds count ALOT, so when I have roughly 3000-4000 quereies an hour pulling information from this table, I personally beleive I need to keep CandidateABMContactlink, and I'm not willing to find out on a production server.
** Now to the Problem at Hand **
I have one query that kicks off about 7 times a day, used to take less than 1 minute before the re-index. NOW it takes 30 Minutes. And it drags the system to a crawl.
I did some looking into it, and this query is using CandidateABMContactlink, and it takes 30 minutes. If it uses PK_Abmcontactlink it finishes in under 45 seconds.
Most queries are simple, "Select Column_names from abmcontacts where identifier in (select contact from abmcontactlink where transmitter = 'XXXXXX')"
This one is:
select * from ABMcontacts where (
(last_modification_date >= '2006-04-28 04:40:03' and last_modification_date <= '2006-05-09 16:41:14')
and EXISTS(select contact from ABMcontactlink where contact = identifier
and EXISTS(select transmitter_id from ABMtransmitter where transmitter_id = transmitter and (dealer = 'XXXX'))))
or
(EXISTS(select contact from ABMcontactlink where
(last_modification_date >= '2006-04-28 04:40:03' and last_modification_date <= '2006-05-09 16:41:14')
and contact = identifier and EXISTS(select transmitter_id from ABMtransmitter where transmitter_id = transmitter and (dealer = 'XXXX'))))
I can't change the query, so how do I make it use the Index I want it to use without removing the index that it is using? (I know there are much better ways to write the above query, I'm not the culprit, if I could re-write it, I would)

This query should always return 1 row with columns visid, cid, visdate, comment. How can I get the value of visdate in textbox1? This already works when the query is in a vb sub but I want to know how to do it this way too.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ connection string here%>" SelectCommand="SELECT * FROM [vis] WHERE ([visID] = @visID)">
<SelectParameters> <asp:ControlParameter ControlID="Label1" Name="visID" PropertyName="Text" Type="Int32" /> </SelectParameters></asp:SqlDataSource>
<asp:TextBox ID="TextBox1" runat="server" Style="left: 117px; position: relative; top: 160px"></asp:TextBox>

Simple example would look like that in MS SQL
SELECT 'a' AS (SELECT language_name FROM language WHERE language_id = 1)
So that the display is
English
a
as we assume that
SELECT language_name FROM language WHERE language_id = 1
returns only English
I have tried to that with a variable but it does not work
declare @that as varchar(15);
set @that = (select language_name_u from language where language_id = 1);
select 'a' as @that
LOL
I just tried another way as i was going to post
declare @that as varchar(15);
set @that = (select language_name_u from language where language_id = 1);
select 'a' as "@that"
and it worked!
Posting anyway so people might answer with a better solution with no variable
Thanks a lot

I have a query:
SELECT *
FROM Mobile_Subscriber
WHERE (sub_ID IN (17, 2, 19))
The result return:
sub_ID sub_name
2 John
17 Alice
19 Eddy
But what I want is:
sub_ID sub_name
17Alice
2John
19Eddy
Is it possible to return the result order by the query with: sub_ID IN (17,2,19)?

I am trying to count the number of Part that is repaired and those that is not repaired, is there a way to combine the following into one result set instead of returning 2? The bold line is the only condition that's different between this 2 query.
I want to display these fields: date_complete, part_categoryid, part_model, repaired, not_repaired
/* parts being repaired */select DATEADD(d,DATEDIFF(d,1,tblAuditPartStatus.auditpartstatus_datecreated),0) as date_complete, part_categoryid, part_model, count(DISTINCT part_id) as repaired from tblPtSingapore INNER JOIN tblAuditPartStatus ON tblPtSingapore.part_Id = tblAuditPartStatus.auditpartstatus_partidwhere (tblAuditPartStatus.auditpartstatus_status = N'COMPLETE')and part_replaced = 0and (part_flag_nff = 0 and part_flag_ntf = 0 and part_flag_beyondrepair = 0)group by DATEADD(d,DATEDIFF(d,1,tblAuditPartStatus.auditpartstatus_datecreated),0), part_categoryid,part_modelorder by part_model, DATEADD(d,DATEDIFF(d,1,tblAuditPartStatus.auditpartstatus_datecreated),0)
/* parts completed but not being repaired */select DATEADD(d,DATEDIFF(d,1,tblAuditPartStatus.auditpartstatus_datecreated),0) as date_complete, part_categoryid, part_model, count(DISTINCT part_id) as not_repaired from tblPtSingapore INNER JOIN tblAuditPartStatus ON tblPtSingapore.part_Id = tblAuditPartStatus.auditpartstatus_partidwhere (tblAuditPartStatus.auditpartstatus_status = N'COMPLETE')and part_replaced = 0and (part_flag_nff = 1 or part_flag_ntf = 1 or part_flag_beyondrepair = 1)group by DATEADD(d,DATEDIFF(d,1,tblAuditPartStatus.auditpartstatus_datecreated),0), part_categoryid, part_modelorder by part_model, DATEADD(d,DATEDIFF(d,1,tblAuditPartStatus.auditpartstatus_datecreated),0)

I've had a thousands instances where this technique would come in handy. Can somebody help me with a way to do a select, like a join parent and child table. Then say something like:
declare @variable varchar(30)
--some kind of loop through the result set
set @variable = queryfieldresult
if (@variable is not null)
begin
select * from table where productId = @variable
end
--end loop
Thanks,
Rick

This is how my table was structured:
Code:
=================================================
|id|cat|amount|
|---------------|---------------|---------------|
|1|1|400|
|1|2|150|
|2|1|600|
-------------------------------------------------
I want to query for a result that would look like this:
Code:
=================================================
|id|cat1|cat2|
|---------------|---------------|---------------|
|1|400 |150|
|2|600||
-------------------------------------------------
How do I do it? I'm working with SQL Server 2000.

I have to pull values from a mysql table, then loop through the result set using the value in an mssql query as shown below. I also have an array ($all_lobs[]) of about 100 values that must be looped through for each value pulled from the mysql table:
$tod=date("n/j/Y",time());
//this is pulling the data from the mysql table
$query2="select CustId from prospect_CustId ";
$result2=mysql_query($query2,$link_id_mysql);
while($custs=mysql_fetch_row($result2))
[Code] .....
If I pull only 100 records from the mysql table, this takes about 1 second to run. However, if I pull 200 records, it takes about 60 secs to run. And, if I pull 300 records, it takes about 200 secs to run. After about 500 records, it takes almost a second per record to run!
Since I have 20,000+ records to pull, this takes hours...
Unfortunately, we are not allowed to modify the mssql tables at all, only query them.
