I'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

Anyone with an idea on how to solve this one? I think I need to write a subquery for the third condition, but I don't have a clue on how to handle this.
Thanks in advance for your help!
hiI need to write a stored procedure that takes input parameters,andaccording to these parameters the retrieved fields in a selectstatement are chosen.what i need to know is how to make the fields of the select statementconditional,taking in consideration that it is more than one fieldaddedfor exampleSQLStmt="select"if param1 thenSQLStmt=SQLStmt+ field1end ifif param2 thenSQLStmt=SQLStmt+ field2end if
I 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!
Hi, 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]

Hi 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. Again and again.Any thoughts?TIA,Gert-Jan van der Kamp
Hi, I've been looling around, but was unable to correctly use a conditional statement in a T-SQL Query. I have this SQL query and in it how I would do if it was C#. If someone could please help me get what I need I would appreciate it a lot. Here is the query:
Code Block
SELECT Ficha, Almoxarifado, [Código do Item], Descrição, Unidades.Unidade, [1ª Contagem], [2ª Contagem], Recontagem, Observações, Cancelar FROM Fichas INNER JOIN Itens ON [Código do Item] = Código INNER JOIN Unidades ON Itens.Unidade = Unidades.ID WHERE Ficha BETWEEN 01 AND 5000 AND Recontagem IS NULL AND
/* What I would do in C#, but need in T-SQL*/ if ([1ª Contagem] > [2ª Contagem]) {
if ([2ª Contagem] / [1ª Contagem] < 0.99)
return true; else {
if ([1ª Contagem] / [2ª Contagem] < 0.99)
return true; }
I really need a help in this. Does anyone know how to accomplish this? Thanks. Regars, Fábio
I'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...
Ok I have a table called allstocks, with a primary key of ticker, I also have a todaysstocks table with a primary key of ticker.
Todaysstock table updates the allstocks table with this statement,
insert into allstocks (exchange,transdate,ticker,[opened date],[closed date],[over/under]) select exchange,[todays date],ticker,[opened date], [closed date],[over/under] from todaysstocks
this works fine, unless the ticker already exists. How do I write the statement, that if the ticker already exists, then update the rest of the fields with the new info, or delete the row and recreate it?
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 ?
currently I am creating a total if the date is between two entered dates:
select sum(case when exigo_data_sync.orders.orderdate between @prevMonthStart and @prevMonthEnd then 1 else 0 end) as PrevMonthCount,
I need to check an additional column for ($1.00) or $1.00. If it contains $1.00 then proceed as normal and add to the total. If it contains ($1.00) then subtract one from the total. Any advice?
I would like to set a variable within my if exists statement, however SQL is throwing and error stating:
Incorrect syntax near '='.
If I remove the if exists, the query runs fine. Is there a reason why this is not working the way I have it and what suggestions can I use to accomplish what I am trying to do, which is store the ID into the permissionID variable
Here is my code block:
Code Snippet
declare @permissionID int;
if exists(select @permissionID = Id from Permission
This 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".
I'm trying to create a batch sql script which first alters some existing tables via the ALTER TABLE command, I then want to alter some existing stored procedures via the ALTER PROCEDURE command within the same batch. I have found that I can encompas the alter table scripts within a conditional IF EXISTS (Begin/End) but not the alter procesdure scripts. I have looked in reference material and have found nothing to suggest this type of operation is not possible. Is this possible? Is this a know bug fixed by a service pack?
I'm using MSSQL and PHP. I've got the following sql statement:
$msquery = IF NOT EXISTS (SELECT SerienNr FROM tbl_Auftrag a WHERE a.SerienNr='PC8') INSERT INTO tbl_Auftrag (BMS_AuftragsNr, SerienNr, AuftraggNr, Zieltermin, Kd_Name) VALUES ('455476567','PC8','1','2006-3-2','Fritz')
The Statement itself works fine, but i've got a problem getting a return value whether the insert has succeed, or not. :confused: mssql_query() always returns true if there occured no error in the statement. But i need to know if the insert procedded or not. I tried:
IF EXISTS(Select ApplicationID from Application Where Application = '&_') Insert Into PCApp(ApplicationID, SystemNetName) Values( , $HoH->{Host}{SystemNetName})
I am not sure what to put in the blank within the Values parenthesis. I need to obtain the ApplicationID that is checked in the IF EXISTS section. But I cannot put a select statement into the Values() section.
Have a View where I need to enter a conditional IF_THEN_ELSE statement in a new field (field has an alias). If this were an Access query I would do following:

When I created an SP in Enterprise Manager, I didn't manually type in the existence check at the inception, a la "if exists (select * from sysobjects...)". I just started with the CREATE PROC AS statement.
I noticed that if I generate a SQL script for the SP, SQL2000 automatically generates the existence check statement.
My question is, can I assume that when the SP is actually executed, SQL2000 does the exists check on its own? I EXEC'd the proc in Query Analyzer with no errors.
I just want to make sure that I don't need to enter the exists statement if it's already being done behind the scenes.
Hi,I'm trying to do calculations in a SQL statement, but depending on onevariable (a.type in example) I'll need to pull another variable fromseperate tables.Here is my code thus far:select a.DeptCode DeptCode,a.Type Type,(a.ExpenseUnit / (select volume from TargetData b where b.type =a.type)) ExpenseFromcalc1 aThe problem... a.Type can be FYTD, Budget, or Target... and dependingon which one it is, I need to make b either FYTDData, TargetData, orBudgetData. I'm thinking a case statement might do the trick, but Ican't find any syntax on how to use Case in an MS SQL statement. EvenIf statements will work (if that's possible), though case would beless messy.Any suggestions would be much appriciative. Thanks...Alex.
Is it possible to have a conditional union statement in a stored proc?Here's an example on the northwind database. If says there's a syntaxerror near the UNION statement.

In MS Access I can do in one SQL statement a update if exists else ainsert.Assuming my source staging table is called - SOURCE and my targettable is called - DEST and both of them have the same structure asfollowsKeycolumns==========MaterialCustomerYearNonKeyColumns=============SalesIn Access I can do a update if the record exists else do a insert inone update SQL statement as follows:UPDATE DEST SET DEST.SALES = SOURCE.SALESfrom DEST RIGHT OUTER JOIN SOURCEON (DEST.MATERIAL = SOURCE.MATERIAL ANDDEST.CUSTOMER = SOURCE.CUSTOMER ANDDEST.YEAR = SOURCE.YEAR)This query will add a record in SOURCE into DEST if that record doesnot exist in DEST else it does a update. This query however does notwork on SQL 2000Am I missing something please share your views how I can do this inSQL 2000.ThanksKaren
What I need to do in seperate a group of numbers into two different categories based on a phase code. I have acheived this through two conditional statements, but when I try to total the numbers that were returned for each group I receive an #error.
This is an example of the switch statement I used in order to return the correct values for the Implemenataion.
I've tried substituting a 0 in for the "" at the end of each statement. I've also tried to take the first statement and put it into its own table field named ImplementationLedger, and them summing it. ie. =SUM(Fields!ImplementationLedger.Value)
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.
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.
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, Master_Jobs.Due_Date, Master_Jobs.Due_Time, Master_Jobs.Next_Action, Master_Jobs.By_Who
FROM Master_Jobs INNER JOIN Note ON Master_Jobs.JobID = Note.FK_JobID INNER JOIN Backup_UserNotes ON Note.NoteID = Backup_UserNotes.BackUp_NoteID INNER JOIN User_Notes ON Note.NoteID = User_Notes.FK_UN_NoteID INNER JOIN Job_Assignments ON Master_Jobs.JobID = Job_Assignments.FK_Master_JobID INNER JOIN Profiles ON Master_Jobs.FK_ProfileID = Profiles.ProfileID INNER JOIN Users ON Backup_UserNotes.BackUp_UserID = Users.UserID AND User_Notes.FK_UN_UserID = Users.UserID AND Job_Assignments.UserID = Users.UserID
WHERE Users.UserID = @UserID AND-- Note.FK_UserID = User_Notes.FK_UN_UserID AND BackUp_Read = 'UnRead')
2) I am not able to get an If/Then statement to work. I am able to use the followingl; however, ideally I would want to have multiple if/else statements:
I'm trying to write a script that would only update a column if it exists.
This is what I tried first:
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Enrollment' AND COLUMN_NAME = 'nosuchfield') BEGIN UPDATE dbo.Enrollment SET nosuchfield='666' END
And got the following error:
Server: Msg 207, Level 16, State 1, Line 1 Invalid column name 'nosuchfield'.
I'm curious why MS-SQL would do syntax checking in this case. I've used this type of check with ALTER TABLE ADD COLUMN commands before and it worked perfectly fine.
The only way I can think of to get around this is with:
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Enrollment' AND COLUMN_NAME = 'nosuchfield') BEGIN declare @sql nvarchar(100) SET @sql = N'UPDATE dbo.Enrollment SET nosuchfield=''666''' execute sp_executesql @sql END
which looks a bit awkward. Is there a better way to accomplish this?

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.
I 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 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" Â 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]= Â (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.
