Mar 23, 2004Hello dbForumers,
Yet another puzzling question. I remember I saw somewhere a particular syntax to select a column based on a conditional predicate w/o using a user defined function. What I want to accomplish is this : SELECT (if column colA is empty then colB else colA) as colC from SomeTable. Possible ? Not possible? Have I hallucinated ?
Thank You!
MS Access Vs. Transact-SQL – Conditional SQL Select Statement Problem
Dec 13, 2004Hi All,
I am trying to write a Transact-SQL statement and am having no success. I have a customers table that has some duplicate Customer Numbers in it, however the records do have a unique Reference Number. I am trying select all records that match a list of Customer Numbers but if there are more than 1 matching Customer Number I only want the one with the largest Reference Number.
My BASIC Select Statement is:
SELECT Cust_Ref_No, Customer_No, Customer_Name, Address1,
Address2, Suburb, State, Postcode, Phone
FROM Customers
WHERE Customer_No IN
(SELECT Customer_No FROM temp_Customers)
Much to my HORROR I found that what I am trying to do is simple in MS Access using the “First” Function – Such as below:
SELECT First(Cust_Ref_No) AS Cust_Ref_No, Customer_No
FROM Customers
GROUP BY Customer_No
ORDER BY First(Cust_Ref_No), Customer_No;
There appears to be no “First” Function in Transact-SQL. Is someone able to show me how to achieve the same results in Transact-SQL as I can get with MS Access (I’d HATE to think that MS Access has more functionality in querying data than SQL Server in any way at all)?
P.S. I really need to run the select statement as one step rather than splitting it up into parts.

Conditional Where Statement
Jul 23, 2007I have a stored procedure that performs a search function with params:@username nvarchar(50)@country nvarchar(50)and like 10 more.A user may provide values for these params optionally.So when the @username var is left blank, there should be no filtering on the username field (every field should be selected regardless of the username)Currently my statement is:select username,country from myUsers whereusername=@username and country=@countryWith this statement when a user provides no value for username the username field selects on ''m which returns ofcourse nothing...What can I do to solve this?Thanks!
View 6 Replies View RelatedSQL Conditional WHERE Statement
Feb 4, 2008Hi, is it possible to do a conditional WHERE in T-SQL? I have a table with a column that consists of a reference that starts with either a single alpha character or two alpha characters followed by four numeric digits (the numeric portion is always unique but the alpha isn’t). E.g. A1234, AB1235, AB1236, C1237, HT1238. What I want to do is select a range of rows based on the numeric portion of this reference column. In other words I want to select say 50 rows starting from row 1000 (rows 1000 to 1050) regardless of whether there is one or two alpha characters preceding the numerics.The Stored procedure I have so far works (using COUNT for testing) for selecting a range of rows that has two alpha's at the start. However, if I simply add an OR to the WHERE to select rows where there is a single alpha in the reference column, when a single alpha reference is found it will fail the first logical check for two alpha's giving an error condition. Therefore, how can I incorporate a conditional WHERE using IF or some alternative method, so that it will also give me all the rows in the number sequence that start with either single or double alpha's within the same SELECT / WHERE statement?
Thanks for any help.ALTER PROCEDURE [dbo].[sp_Test]

Conditional WHERE Statement?
Jul 23, 2005Hi all,I have one for all the blackbelters out there: is there a way i canmake a stored procedure where i can control the where statement withvariables? I have to do some complex transformations to get compose afact table for MSAS and there a a lot of similarities between thequeries and a few differences because of different account methodsetc. (booking in starting date, booking stuff on order entry datesetc) I want to put a combination of different rules in differentmembers of dimensions.An example of what i mean:CREATE STORED PROCEDURE dbo.FILLFACT (@PAR1, @PAR2)ASINSERT INTO FactTable (blah blah)SELECTIF @PAR1 = 'OrderDate'SourceView.OrderdateELSESourceView.StartDate,etc etc...FROMSourceViewWHEREIF @PAR2 = 'WholeTable'1=1IF @PAR2 = 'Incomplete'EndDate IS NULL OR EXIST (SELECT * FROM Exceptions WHERE...., etc)This way i could fill my fact table withEXEC dbo.FillFact 'beginDate','Wholetable'EXEC dbo.FillFact 'begindate', 'Rulebook1'EXEC dbo.FillFact 'BeginDate', 'Exceptions'etcetera.This is not an actual SQL script i use, just an example of what i'mtalking about. Or maybe i could pass the where statement entirley as avariable? But i can't use SET @PAR1 = 'EndDate IS NULL' and then useWHERE @PAR1 can I?I hope i'm making sense. Does anyone know if this is possible? Rightnow i have a procedure that is composed of a dozen of sql scripts thatare mostly the same, but i have to copy it for every combination ofsituations and then, of course, new stuff has to be added on 12different places.

Using The IF EXISTS Conditional Statement
Apr 5, 2007I'm trying to gather some user statistics based on 3 conditions. First I want to check if the referring querystring is already in the database. If not insert it into the db. Second, if the querystring is already in the database, then check if the ip-address of the user is already in the database. If it is, then check if the ip address was inserted today. If not, update the "refCountIn" field with +1. The problem lies in the third condition where we check if the ip-address was inserted today and if false, update the "refCountIn" field with +1 and if true, do nothing.Below is the code I have until now: 1 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

SQL Help: Conditional Statement Using Inserted
Oct 29, 2007I'm learning SQL and here I'm trying to use two things that I'm not familiar with - IF statements and the Inserted temporary table.
Here's the background - skip this paragraph if you like. I'm working on a tasking system for the Help Desk - they get requests from the web site for various items and I break up the request into Software, Hardware, Accounts, etc tables and list the status of each item as "Requested". I'm also keeping a Tasks table to make work orders for each item requested. I've got triggers on the Accounts and Hardware tables that automatically make a new task for those items but the Software is more tricky because all software for a given request should be just one task. Software installs are all done by one person at the same time.
So I'm trying to make a trigger that creates a new Task when a new Software record is inserted. But if a task already exists with the same RequestID (meaning they requested two peices of software and this is the second one), then I just want to update the task already created. Here's what I got:
1 CREATE TRIGGER [NewSoftwareTask]
2 ON [dbo].[Software]
3 AFTER INSERT
4 AS
5 BEGIN
6
7 -- If a software task already exists for this request
8 -- then update it. Otherwise create a new task.
9
10 if exists(select TasksID
11 from Tasks
12 where Tasks.RequestsID = inserted.RequestsID and
13 TasksType = 'Software')
14 BEGIN
15 UPDATE [BGHelpdesk].[dbo].[Tasks]
16 SET [TasksDescription] = [TasksDescription] + vbcrlf + "Install " + inserted.SoftwareType + ". " + inserted.SoftwareComments
17 WHERE Tasks.RequestsID = inserted.RequestsID and
18 TasksType = 'Software'
19 END
20
21 else
22
23 BEGIN
24 INSERT INTO [BGHelpdesk].[dbo].[Tasks]
25 ([RequestsID]
26 ,[TasksType]
27 ,[TasksSubType]
28 ,[TasksTitle]
29 ,[TasksDescription])
30 SELECT
31 s.RequestsID
32 ,'Software'
33 ,s.SoftwareType
34 ,'New ' + s.SoftwareType + ' Account for Request ' + cast(s.RequestsID AS varchar)
35 ,s.SoftwareComments
36 FROM Software s join
37 inserted ON s.SoftwareID = inserted.SoftwareID
38 END
39 END
40 GO
It keeps balking at lines 12 and 17 saying "The multi-part identifier "inserted.RequestsID" could not be bound." The ELSE statement is what I use on the other tables and it works fine so the inserted temp record seems pretty straightforward but I must be doing something wrong...

IIf ANY Value In Table Conditional Statement
Oct 12, 2007This is probably quite simple, but it isn't sticking out at me.
In a simple table with two groups, I want to conditionally set the color of the first group to red or green based upon whether ANY value for this field equals a particular string.
I know how to conditionally set the color of the field. However, the below code appears to only compare the FIRST value in Fields!myField.Value to the string "bad". I want it to return "Red" if ANY of the values for Fields!myField.Value = "bad".
Code Block=IIf(Fields!myField.Value = "bad", "Red", "Green")
myField is ouput in the detail scope if that makes any difference.
Is this possible?

Conditional Where Clause W/ Case Statement Possible?
Sep 25, 2007Greetings,
After many hours search many forums and many failed experiments, I figure it's time to turn to the experts.
I need to execute a query that changes the returned data based upon a parameter's value. In my example below, the lob field contains both text values and nulls.
SELECT uniqueID, lob, xdate
FROM mytable
WHERE
CASE WHEN @myparam = 'ALL'
THEN
xdate >= '2007-09-01'
ELSE
xdate >= '2007-09-01' or
lob = @myparm
END
I've experimented with various forms of the LIKE function, checking for null/not null and keep coming up blank.
I thought about using an IF statement and creating different versions of the entire statement, however, in real-life I need to do this with four fields using four parameters (one for each field). The permutations are a little too much.
Any ideas?

Conditional Select
Nov 8, 2007I am trying to write query that will select calls that only show up when the resolution returned from the case in the sub query is 'y'. When I do the group by some calls will show up twice because of a null and a 'y' resolution return. I want to only select a call if there is a 'y' that shows for all resolutions associated with that call. If there are any null resolutions for the call I don't want it to show up in my returned values. This is what I have so far, but I can't figure out how to make it drop both instances of the callID if one instance is null.
Code:
SELECT C.CallID, P.PrimarySupportGroupID, P.PrimaryTeamName, T1.Resolution, CASE C.CallID WHEN T1.Resolution IS NOT NULL THEN 'Y' ELSE 'N' END
FROM HEAT.dbo.CallLog C,
(SELECT CallID, CASE WHEN A1.Resolution = '' THEN 'Y' ELSE NULL END AS Resolution
FROM HEAT.dbo.Asgnmnt A1) T1, HEAT.dbo.Profile P
WHERE C.CallID = T1.CallID AND C.CustID = P.CustID AND (P.PrimarySupportGroupID = 'ATS') AND (P.PrimaryTeamName = 'Beta')
GROUP BY C.CallID, P.PrimarySupportGroupID, P.PrimaryTeamName, T1.Resolution
If anyone could help me out with this or at least give me a little information and point me in the right direction I would really appreciate it.

SQL Server 2012 :: Stored Procedure With Conditional IF Statement Logic
Aug 9, 2015I have a data model with 7 tables and I'm trying to write a stored procedure for each table that allows four actions. Each stored procedure should have 4 parameters to allow a user to insert, select, update and delete a record from the table.
I want to have a stored procedure that can accept those 4 parameters so I only need to have one stored procedure per table instead of having 28 stored procedures for those 4 actions for 7 tables. I haven't found a good example online yet of conditional logic used in a stored procedure.
Is there a way to add a conditional logic IF statement to a stored procedure so if the parameter was INSERT, go run this statement, if it was UPDATE, go run this statement, etc?
I have attached my data model for reference.

View 14 Replies View RelatedBest Practice For Conditional Insert Else Select?
Aug 7, 2007I have several places where I need to get the id (primary key) of a resource, inserting a row if the resource does not exist (i.e. an artificial key to be used as an FK for another table). I should probably change this varchar key lookup to use a hash index, but that is beside the point.
So the table is essentially like:
CREATE TABLE MyLookup(id int identity primary key nonclustered, mykey varchar(256));
CREATE CLUSTERED INDEX mylookup_cidx_mykey ON MyLookup(mykey);
I see two main approaches for how I can do my get-id-with-insert-if-needed.
(Approach 1)
DECLARE @id INT;
SELECT @id = id FROM MyLookup WHERE mykey = 'some key value';
IF (@id is null)
BEGIN
INSERT MyLookup ('some key value');
SET @id = SCOPE_IDENTITY();
END
(Approach 2)
DECLARE @id INT;
INSERT MyLookup SELECT 'some key value' WHERE NOT EXISTS (SELECT id FROM MyLookup WHERE mykey = 'some key value');
IF (@@ROWCOUNT = 0)
SELECT @id = id FROM MyLookup WHERE mykey = 'some key value';
ELSE
SET @id = SCOPE_IDENTITY();
From some quick tests in profiler, approach 2 seems to be a bit faster and have lower resource utilization. But I'm not sure if it maybe takes some more aggressive locks even in the unnecessary case where the mykey row value of 'some key value' already exists. Approach 2 also looks cleaner to me, but I don't mind a bit of extra code if it gives me better scalability through less lock contention.
Any tip on what is considered the best practice for a conditional insert like this, or a tip on how to get detailed lock info for a query? The lock info for profiler was all greek to me, it just had a hex value with each lock acquired/released, so I have no idea what it was telling me. Is my only solution to just run exhaustive tests and look at the perf numbers from the black box?
Stored Procedure With Conditional Select Statment

Multiple Tables Used In Select Statement Makes My Update Statement Not Work?
Aug 29, 2006I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
TSQL - Use ORDER BY Statement Without Insertin The Field Name Into The SELECT Statement
Oct 29, 2007Hi guys,
I have the query below (running okay):
Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
FROM myTables
WHERE Conditions are true
ORDER BY Field01
The results are just as I need:
Field01 Field02
------------- ----------------------
192473 8461760
192474 22810
Because other reasons. I need to modify that query to:
Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
INTO AuxiliaryTable
FROM myTables
WHERE Conditions are true
ORDER BY Field01
SELECT DISTINCT [Field02] FROM AuxTable
The the results are:
Field02
----------------------
22810
8461760
And what I need is (without showing any other field):
Field02
----------------------
8461760
22810
Is there any good suggestion?
Thanks in advance for any help,
Aldo.
