I have a query with a conditional expression that I can do just fine in Access but I am having a bear of a time trying to create a similar SQL View. Baiscally I want to say, if column A is null, use value B else use value C.
In Access the SQL is this:
SELECT IIf([Categorycode] Is Null,[tblconstituents].[CASNumber],[categorycode]) AS Casnumber, Sum(qryweldingrod3a.CFume) AS CFume, Sum(qryweldingrod3a.cslag) AS cSlag FROM qryweldingrod3a INNER JOIN tblconstituents ON qryweldingrod3a.CASNumber = tblconstituents.CASNumber GROUP BY IIf([Categorycode] Is Null,[tblconstituents].[CASNumber],[categorycode]);
But I know you can't use the IIF statement in SQL so I was trying CASE and was still coming up empty handed. Here is what I produced in SQL but it didn't work:
SELECT SUM(dbo.RecycleWR_qryWeldingRod3a_LBS.CFume) AS CFume, SUM(dbo.RecycleWR_qryWeldingRod3a_LBS.CSlag) AS cSlag,
CASNumber = CASE Type WHEN categoryCode IS NULL THEN dbo.tblConstituents.CASNumber ELSE CategoryCode END, FROM dbo.tblConstituents INNER JOIN dbo.RecycleWR_qryWeldingRod3a_LBS ON dbo.tblConstituents.CASNumber = dbo.RecycleWR_qryWeldingRod3a_LBS.CASNumber GROUP BY dbo.RecycleWR_qryWeldingRod3a_LBS.CASNumber
Hi, I need to create a conditional expresssion where if a null value is found, then a letter "N" must be inserted. I create this expression but didnt work: (COL1 == NULL) ? "N" : COL1 So, if COL1 is null, then N .. but if it is nt null tehn COL1 = COL1 I think i', having a problem expressing the null. Any idea for this? Thanks!
I have as csv-file wich I import into an SQL Server table. Now I want to do some checks on it. I use a conditional split to direct data to the other tables (1 table for the correct data, 1 table for the rejected data).
Is it possible to use a regular expression in a case in a conditional split to check if a columns has the right format?
I'm using a conditional split to discriminate modified records. My expression looks like this: col1_source != col1_dest || col2_source != col2_des.....and so on. I use OLE DB Command afterward to update modified records.
It all works fine if no columns evaluate to null. If any (source or dest.) evaluates to null, component fails.
Any tips how to solve a problem?
It has to work like this:
If colX_source is null and colX_dest is not null --> Update If colX_source is not null and colX_dest is null --> Update If both colX_source and colX_dest are null --> No update
p.s. i apologize if a similar thread exists, I haven't found something of use to me.
I want to do conditional processing depending on values in the rows of a CTE. For example, is the following kind of thing possible with a CTE?:
WITH Orders_CTE (TerritoryId, ContactId) AS ( SELECT TerritoryId, ContactId FROM Sales.SalesOrderHeader WHERE (ContactId < 200) ) IF Orders_CTE.TerritoryId > 3 BEGIN /* Do some processing here */ END ELSE BEGIN /* Do something else here */ END
When I try this, I get a syntax error near the keyword 'IF'
Any ideas? I know this kind of thing can be done with a cursor but wanted to keep with the times and avoid using one!
I think I know the answer to this but thought I'd ask anyway.
I have a conditional split to check a column for null values or empty string values. It looks like this:
(!ISNULL(Ballot)) || (LEN(TRIM(Ballot)) > 0) My question is: Are both sides of the expression evaluated? My testing says yes, because a Null value causes an error. Is there a way to short circuit the evaluation like the || operator in C# or the (less than elegant, and seemingly threatening) OrElse operator in VB? Whats the best alternative:
A slightly more complex expression that turns a null value into an empty string
A script component
Two conditional splits
Two paths out of one condtional split
I went with the first option, here is the expression I came up with:
I'm trying to put conditional formatting on a field, that behaves as follows:
The data in the field is varchar, and sample data is either:
NULL 3.0 :0 11.7 :1 (these are ratios of a sort)
I want to evaluate the first 3 characters of the string as numbers.
Example: Mid(fieldvalue,1,3) = "3.0" or "11."
Any data that is greater than 1.99, I want to make the background dark red, anything else including nulls, zebra formatting. I have the following expression built so far and it appears to work, except when the value is null. If the value is null, it leaves the background color white.
This is the warning: [rsRuntimeErrorInExpression] The BackgroundColor expression for the text box "Asthma" contains an error: Input string was not in a correct format.
=iif( isnothing(Fields!Asthma.Value) ,(IIf(RowNumber(Nothing) Mod 2 = 0,"#b8cce4","#dbe5f1")) ,(iif(mid(Fields!Asthma.Value,1,3)>1.99 ,"DarkRed" ,IIf(RowNumber(Nothing) Mod 2 = 0,"#b8cce4","#dbe5f1"))))
My logic is, if the field is null, zebra format, if mid of the value is > 1.99, dark red, everything else zebra formatting. As I said, this seems to work except for nulls.
I have a varchar field in my table that stores our project numbers as such: 05-001-1, 05-001-2, 05-001-3, 05-002-1, 05-003-1, 05-003-2, etc. I am doing an order by desc on this column and it is returning something like this:
So it sorts all the 1's first, then the 2's then the 3's etc. If the numbers went up to 20 then 05-001-20 would appear after 05-001-2 and before 05-001-3. How can I get it to sort numberically i.e. 1-12?
Is there a way in order to execute a subscribed report based on a certain criteria?
For example, let's say send a report to users when data exist on the report else if no data is returned by the query executed by the report then it will not send the report to users.
My current situation here is that users tend to say that this should not happen, since no pertinent information is contained in the report, why would they receive email with blank data in it.

I have created 1 report with 2 datasets. This report is attached to the 1st dataset.For example,1st one is "Smallappliances", 2nd is "Largeappliances".
I created a tablix and, the 1st column extracts Total sales per Sales person between 2 dates from 1st dataset (Small appliances). I used running values expression and it works fine.
Now, I would like to add another column that extracts Total sales per sales person between 2 dates from 2nd dataset (Large appliances). I am aware that I need to use Lookup expression and it is giving me the single sales value rather than the total sales values. So, I wanted to use RunningValue expression within lookup table to get total sales for large appliances.
This is the lookup expression that I added for the 2nd column.
I get this error when I preview the report.An error occurred during local report processing.The definition of the report is invalid.An unexpected error occurred in report processing.
I have the following code in the color property of a textbox. However, when I run my report all of the values in this column display in green regardless of their value.
I want to know how I can create conditional FROM WHERE clauses like below ..
SELECT X,X,X FROM CASE @intAltSQL > 0 Then Blah Blah Blah END CASE @intAltSQL = 0 Then Blah END WHERE CASE @intAltSQL > 0 Then Blah Blah Blah END CASE @intAltSQL = 0 Then Blah END
Im faced with the following design issue.. on my site there are different profiles: a city profile, a restaurant profile and a user profile. in my DB:City profiles are stored in tbCities cityID int PK shortname nvarchar(50) forumID int FK (...) Restaurant profiles are stored in tbRests restID int PK shortname nvarchar(50) forumID int FK (...) User profiles are stored in tbUsers userID int PK shortname nvarchar(50) forumID int FK (...) as you can see a single ID value (for CityID,restID or userid) might occur in multiple tables (e.g. ID 12 may exist in tbRests and in tbUsers)Each of these profile owners can start a forum on their profile. forumID in each of the above tables is a FK to the PK in tbForums:forumID intforumname nvarchar(50) (...) Now imagine the following: a site visitor searches ALL forums...say he finds the following forums:ForumID Forumname1 you opinion on politics2 is there life in space?3 who should be the next president of the USA? a user may want to click on the forum name to go to the profile the forum belongs to.And then there's a problem, because I dont know in which table I should look for the forum ID...OR I would have to scan all tables (tbCities,tbRests and tbUsers) for that specific forumid,which is time-consuming and I dont want that! so if a user would click on forumID 2 (is there life in space?) I want to do a conditional inner join for the tablecontainingforumID (which may be tbCities,tbRests or tbUsers) select tablecontainingforumID.shortname FROM tablecontainingforumID tINNER JOIN tbForums f ON t.ForumID=f.ForumIDwhere f.ForumID=2 I hope my problem is clear..any suggestions are welcome (im even willing to change my DB design if that would increase effectivity)
I encounter a T-Sql problem related to if conditional processing:The following script execute an insert statement depending on whether column 'ReportTitle' exists in table ReportPreferences. However it gets executed even when ReportTitle column is not present.Could anyone offer some advice?

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]

I have an SqlDataSource that uses a value from the query string in the WHERE clause of the sql statement. The sql is something like this: SELECT * FROM myTable WHERE myfield = @myfield and I have the QueryStringParameter setup like this: <asp:QueryStringParameter Name="myfield" QueryStringField="myfield" /> What I need is for the sql statement to return all records in the case that "myfield" is not defined in the query string. How would I implement this? Thanks, Joshua Foulk
Hello all, my update statement works as expected, but lacks some conditional logic. How can I change the statement to not decrement qtyonhand if the quantity is 0? Additionally, I would need to return to the calling application something that would allow me to populate a label with a message to the user.. How can that be accomplished? Here is my sproc:CREATE PROCEDURE [webuser].[cssp_removeItem] @lblID int AS Update cstb_inventoryset qtyonhand = qtyonhand -1where Id = @lblIDGO Here is my app code: Try Dim cmd As SqlCommand = cn.CreateCommand cmd = New SqlCommand("cssp_removeItem", cn) cmd.CommandType = CommandType.StoredProcedure With cmd cmd.Parameters.Add("@lblId", SqlDbType.Int).Value = lblId.Text End With If Not cn.State = ConnectionState.Open Then cn.Open() End If cmd.ExecuteNonQuery() Catch ex As Exception Response.Write(ex.ToString) Finally If Not cn.State = ConnectionState.Closed Then cn.Close() cn = Nothing End If
Hi, [SQL 2005 Express] I would like a DropDownList to be populated differently depending on the selected value in a FormView. If the FormView's selected value (CompanyID) is 2, then the DropDownList should show all Advisers from the relevant Company. Otherwise, the DropDownList should show all Advisers from the relevant Company where the TypeID field is 3. Here is the SQL for case 1: SELECT AdviserID, AdviserName FROM Advisers WHERE (CompanyID = @CompanyID). Here's the SQL for case 2: SELECT AdviserID, AdviserName FROM Advisers WHERE (CompanyID = @CompanyID) AND (TypeID = 3). Here's my best (failed) attempt to get what I want: SELECT AdviserID, AdviserName FROM Advisers WHERE IF @CompanyID = 2 THEN BEGIN (CompanyID = @CompanyID) END ELSE BEGIN (CompanyID = @CompanyID) AND (TypeID = 3) END I've also tried: SELECT AdviserID, AdviserName FROM Advisers WHERE CASE @CompanyID WHEN 2 THEN (CompanyID = @CompanyID) ELSE (CompanyID = @CompanyID) AND (TypeID = 3) END and SELECT AdviserID, AdviserName FROM Advisers WHERE CASE WHEN (@CompanyID = 2) THEN (CompanyID = @CompanyID) ELSE (CompanyID = @CompanyID) AND (TypeID = 3) END I'd be very grateul to know (a) what the correct syntax for this is and (b) if it can be achieved using a parametised query, rather than a stored procedure. Thanks very much. Regards Gary
I'm wondering if one can designate a conditional foreign key that relates to one of many different tables depending on the "type" column in the foreign key's. My goal is to come up with some SQL code that will allow for this in a Create table statement. (By the way I'm using MS SQL-7 but I'm wondering if this can be done in general.)
I have two simple cases below that show illustrate what I'm trying to do: Thanks in advance, -JerryZZ
--------------------------------------------------------- Case 1: The foreign key relation is to a primary key
Table: Invoices -Fields: ---InvoiceID ..... (primary key) ---BilleeID ...... (fkey to Manfacturers.ManfID IF BilleeType=M) ...................(fkey to Distibutors.DistID IF BilleeType=D) ---BilleeType .....(constraint = M or D)
--------------------------------------------------------- Case 2: The foreign key relation is to a unique "not null" non-primary key
Table: InvoicesEmail -Fields: ---InvoiceID ..... (primary key) ---EmailAddress .. (fkey to Manfacturers.EmailAddress IF BilleeType=M) ...................(fkey to Distibutors.EmailAddress IF BilleeType=D) ---BilleeType .....(constraint = M or D)
Hi, ladies and gentelmen! Can you help me with following trouble: I got a table (let it be called SomeTable) in which there's one nullable field (let's call it SomeField) among many others. PRIMARY KEY for SomeTable is of INT IDENTITY type. Business rules are following: only records that have SomeField IS NULL can be deleted, so I need to perform conditional delete (for cases like DELETE SomeTable). I don't like idea about using SP here, so I tried to solve the task by means of trigger. However, when DELETE clause is used within a transaction and there're records affected by the trigger that don't match business rule, trigger uses ROLLBACK TRAN and then deletes only matching rows from target table. Everything works fine with our SomeTable, but not so fine with the transaction, because due to ROLLBACK TRAN statement in trigger body this transaction is rolled back (as it is described in documentation). But I don't wanna ALL my transaction rolled back! So, is there in SQL Server 7.0 any way to rollback only changes that caused trigger to fire? Something like ROLLBACK TRIGGER?
I would like to write the following (pseudo) stored procedure, but am having problem with the syntax:
Create Procedure spSort @IDContract nvarchar(10) @SortOrder int
SELECT * FROM Contracts WHERE IDContract = @IDContract IF @SortOrder = 0 BEGIN ORDER BY ContractDate END IF @SortOrder = 1 THEN BEGIN ORDER BY ShippingPeriod END
The problem is in conditionally setting the sort order. The actual sp is quite complex and I don't really want to have to use two procedures (one for ordering by ShippingPeriod and one for ordering by ContractDate

Now how can I reverse this to insert all the values back to tbl FULLSOURCE from maybe an updated SSOTARGET Tbl. FULLSOURCE looks like this:
I 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.
