for example: In table A, there is column 1, column 2, column3. In table B, there is column 4, column 5 and column 6.
column 1 and column 2 are primary keys for table A and table B. The relationships between table A and table B are column 2 and column 5; column3 and column 6. but optional (ie. when data exists in column 2, then column3 is null)
how can i set the relationship? because one of the columns data is null each time, error always occurs.
I have four tables with relationships as shown. They have a circular relationship and so one of the relationships is forced to be inactive.
  Operation (Commodity, OperationKey)  ==========> Commodity (Commodity)                      /                                                                        /                       |                                                                         |   Advice (OperationKey)      ====== (inactive)=======> Operation Commmodity (Commodity, OperationKey)
However, the userelationship function does not override the active relationship between Operation & Advice and so the measure is limited to Advices directly filtered by the Operation table.
If I delete the relationship between Operation and Advice, then the measure works as expected i.e. Operation indirectly filters Operation Commodity which filters Advice.
I have a select proc that will take a bunch or criteria parameters. Based on how many are not null I would like to decide how many inner joins to do. for example:
select H1.Priceid as HotelPriceId,H2.Priceid as AirPriceId, H1.VendorPackageId from ( select HA.PriceId, HA.VendorPackageId from Criteria HA Inner Join ( select VendorPackageId from ValidVendorPackages where Vendor = 'SBT' and Sitecode = 'system' and PackageType = 'AHCF' )HB on HA.VendorPackageId = HB.VendorPackageId and ( CriteriaId in ( select CriteriaID from ValidItemCriteria where Destination = 'LAS' and LengthOfStay = 5 and Ages = 'A2' and ComponentType = @ComponentType_1 and ValidItemType = @ValidItemType_1 and ItemValue = @ItemValue_1 ) )
)H1 INNER JOIN ( select HA.PriceId, HA.VendorPackageId from Criteria HA Inner Join ( select VendorPackageId from ValidVendorPackages where Vendor = 'SBT' and Sitecode = 'system' and PackageType = 'AHCF' )HB on HA.VendorPackageId = HB.VendorPackageId and ( CriteriaId in ( select CriteriaID from ValidItemCriteria where Destination = 'LAS' and LengthOfStay = 5 and Ages = 'A2' and ComponentType = @ComponentType_2 and ValidItemType = @ValidItemType_2 and ItemValue = @ItemValue_2 ) ) )H2 on H1.Priceid = H2.priceId Inner Join ( select HA.PriceId, HA.VendorPackageId from Criteria HA Inner Join ( select VendorPackageId from ValidVendorPackages where Vendor = 'SBT' and Sitecode = 'system' and PackageType = 'AHCF' )HB on HA.VendorPackageId = HB.VendorPackageId and ( CriteriaId in ( select CriteriaID from ValidItemCriteria where Destination = 'LAS' and LengthOfStay = 5 and Ages = 'A2' and ComponentType = @ComponentType_3 and ValidItemType = @ValidItemType_3 and ItemValue = @ItemValue_3 ) ) )H3 on H2.Priceid = H3.priceId
if values are only passed in from @ComponentType_1,@ValidItemType_1,@ItemValue_1 I dont want to do any inner joins.
If its passed in for @ComponentType_1,@ValidItemType_1,@ItemValue_1 & @ComponentType_2,@ValidItemType_2,@ItemValue_2 I want to do the first Inner Join.
and of course if I get all 3 sets of criteria I want to do both the inner joins. I know I can cut and past this thing 3 times with an if statement but that isn't going to be practical.
Is it possible to define an argument as optional for a UDF? I have a financial calculation that may or may not require a defined date range depending on the status of an individual item. Is there a way to avoid requiring the date range where it's not necessary?

If a parameter is null, I dont want it to be in the WHERE clause. I dont want to use a string parameter and execute a "string" select. I dont want to use a combination of IF to check everything ...
Is there an option in a stored procedure whereby a parameter can be flagged as optional? I have a stored procedure with 2 parameters, Product and Date, and I would like to be able to just pass the Product, or pass Product and Date from an Access project. Is this possible?
Hello, Is it possible to define optional parameters for a stored procedure? What I want is to create a search with about 8 parameters, but most users will only use 3 or 4, so It would be nice If I could only provide the used parameters in my code. And have sql give the unused parameters a default value (possibly %) thx.
I have a package in DTS that I am tryinig to work with. We have a few queries that will export the same exact table to a text file. I am trying to make it so we can pull a previously created text file from a central "CommonFile" folder. In this package I have a Execute Package Task. This second package is only for creating this common txt file. I want this step to only run if the file is non-existant (i.e. someone deleted/moved it by accident) or if it is over a week old (the database we pull it from it updated on sundays). I can run it so the comment txt file get created first thing on monday, but I still want a failsafe in there incase the file is deleted/moved or the package to create it fails.
I have an ActiveX script set up which checks if the file exists and if it does then checks to see how old it is Then from there I would like to jump to a different area of my package:
Code Snippet
Dim pkg Dim stpbegin
Set objFSO = CreateObject("Scripting.FileSystemObject")
If objFSO.FileExists(".txt") = TRUE THEN msgbox("COPY") Set objFile = objFSO.GetFile(".txt")
Dim today Dim thisweek
today = date() thisweek = (Weekday(date())-2)
IF thisweek < 0 THEN thisweek = 6 'Sunday Weekday() = 1 so this will put it at the end of the week.
IF (date() - thisweek) <= objFile.DateLastModified THEN msgbox("COPY") set pkg = DTSGlobalVariables.Parent set stpbegin = pkg.Steps("DTSStep_DTSActiveScriptTask_4") stpbegin.ExecutionStatus = DTSStepExecStat_Waiting ELSE msgbox("CREATE") set pkg = DTSGlobalVariables.Parent set stpbegin = pkg.Steps("DTSStep_DTSExecutePackageTask_1") stpbegin.ExecutionStatus = DTSStepExecStat_Waiting END IF
ELSE msgbox("CREATE") set pkg = DTSGlobalVariables.Parent set stpbegin = pkg.Steps("DTSStep_DTSExecutePackageTask_1") stpbegin.ExecutionStatus = DTSStepExecStat_Waiting END IF
Main = DTSTaskExecResult_Success End Function
The problem I am having is despite the ActiveX script the package will run the execute package task no matter what (i dont see a way to post pics so I will try to draw bellow). I think this is due to me having a success between the ActiveX and the EPT. This is the only way I know of how to step this up. If i do a completion it will also do the EPT and if I do a failure it won't do anything at all after it.
So basically I want this pagage to jump over the DTSExecutePackageTask_1 if the file checks out as okay. Does anyone have a suggestion of how I can set up this package?
I'm using an application that is generating some SQL scripts for SQL Server 2005. I'm trying tweak it so that I can run it on SQL Server 2000.
The line that I'm having trouble with is:
CREATE INDEX FKFFF41F9960601995 ON alf_access_control_entry (permission_id);(optional)
The key word "(optional)" is causing trouble. I understand this keyword, when used in SQL Server 2005, let's the script continue and complete when errors are detected.
What is the alternative syntax to use in SQL Server 2000?
Hi, I'm having a problem trying to do optional items in where clause. I'd appreciate some help, heres the code.
select DFD.Col1 as 'Col1',CMD.Col2 as 'Col2' from Control as DFD,MetaData as CMD,Columns as DC,Tables as DT where DFD.GroupID in ({0}) and
(CMD.MetaDataId = DFD.PrimaryID -- or CMD.MetaDataId = DFD.ForeignID -- These are the problem 3 lines or CMD.MetaDataId=DFD.HumanColumn) --
and DFD.Disabled='N' and CMD.Disabled='N' and DC.ColumnsId=CMD.ColumnId and DC.Disabled='N' and DT.TablesId=DC.TableID and DT.Disabled='N'
-- For the problem rows I need to be able to optionally search if they're = to MetaDataID. Right now this query will return only rows that have metadataid = PrimaryID or Foreign, Human. I need to be able to return all rows with the optional dependancies.
Is it possible to set up a one to one relationship between two tables, where one side of the relationship is optional? For example, I have two tables "Applicant", and "Client":A client will always have one applicant
I need to use a parameter in a stored procedure that is optional and if it is optional I need all records returned, even if there is an entry in the field that the parameter is appllied to. Is this possible? I know I can assign a default value. but the value in the field could be one of many choices. I want to be able to specify a choice and have only those records returned or leave it blank and return all records.
I've been away for a while but now that I'm back one if the first things I noticed is how many of the problems on this forum could have been easily avoided by simply normalizing the database in question.
For those of you without formal SQL training, know this: You have to normalize your database. This is part of the process of database development. You can not just whack together a few tables in whatever way is the easiest for the problem at hand, because eventually your requirements will expand and then you need your data to be flexible.
Seriously, in the last 3 weeks I've seen many many questions where it is obvious that the problem is a flawed DB design, but all the so-called SQL gurus here will just answer the question without addressing the fact that the problem lies much deeper.
Here's a link I found on Google: http://www.cse.unsw.edu.au/~cs3710/PMmaterials/Tutorials/normalise.htm
I have a web page I want to run a stored procedure from. In the web page I have three drop downs Business Area, Business Unit and Reporting PeriodThe drop downs determine whether all projects are returned or all projects for a certain business unit / business area or month.This means I have to tailor my sql statement accordingly. What I want to know is can I append sections of a sql statement ie add or subtract more where clauses depending on the values pulled in from the web page.At the moment I have only accounted for 2 variables and that has caused me to create 4 IF statements depending on the values. 3 variables would cause even more IF statements and multiple combinations which I am trying to avoid.
I need some help... I'm trying to execute a stored procedure and I'm getting this message

Hello guys, I want to implement a searching with a stored procedure. As an example I have a table like > tableA ; Id,Name,Surname,Gender(bit) 0 -Male , 1 - Female
If i want to choose all records that are male, I could simply have a query like this : SELECT * FROM tableA WHERE Gender = 0 and vice versa for female. If i want to choose all rows in the table i should omit where clause. The problem is , when i use a stored procedure i should send a parameter. And i dont know if there is a possible way to to do this. When i try such procedure : CREATE astoredprc (@gender bit) AS SELECT * FROM tableA WHERE Gender = @Gender GO -- In such prc. i can only get rows with a where clause. What if i want to use the same procedure with all rows and omiting where. I have many fields like this and I m unsure if I should use a text query or not ... Thanks for all of u from now on
I want the procedure to process 1) all data is no dates are presented 2) all data after the start date, if no end date is supplied 3) all data before the end date if no start date is supplied 4) all data between the start and end dates if both are supplied
Now, instead of an elaborate conditional, I added this to the WHERE clause of my SQL statement:
AND ((@start_date IS NULL OR service_date >= @start_date) AND (@end_date IS NULL OR service_date <= @end_date))
It works fine, but I want to know if anyone has a different/better way of doing it, or if there is a big bug waiting to happen here.
I typically don't like to create multipurpose routines in my code, but this is a better approach for my in a non-object-oriented world of SQL.
Hi, I wish to create a user defined funtion in sqlserver2005 with optional parameter list. So at the time of function calling the parameters should be a optional one. How can i do this? please help me .
I would like to use a where clause that can make use of any combination of the 4 parameters (the two dates should be together)
1 2 3 4 / x x x x / x x x x / x where x = not supplied / = supplied a value
(and so the list continues) Can anybody assist me or give me insights on how to go about this complicated WHERE construct without listing all the probable combinations of the supplied parameters in series of IF statements.
Is it possible to have the field as a unique key and a optional one?It is like.. for example, office code has to be unique (cannot beduplicated with the same code) and it could be null too.
Dear GroupI'd like SQLManager to start on Win98. I've added it to StartUp and itshows in the right-bottom corner of the desktop upon operating systemstart but the database still shows as stopped.

Hi All!General statement: FK should not be nullabe to avoid orphans in DB.Real life:Business rule says that not every record will have a parent. It isimplemented as a child record has FK that is null.It works, and it is simpler.The design that satisfy business rule and FK not null can beimplemented but it will be more complicated.Example: There are clients. A client might belong to only one group.Case A.Group(GroupID PK, Name,Code…)Client(ClientID PK, Name, GroupID FK NULL)Case B(more cleaner)Group(GroupID PK, Name, GroupCode…)Client (ClientID PK, Name, ….)Subtype:GroupedClient (PersonID PK/FK, GroupID FK NOT NULL)There is one more entity in Case B and it will require an additionaljoin in compare with caseAExample: Select all clients that belongs to any groupSummary Q: Is it worth to go with CaseB?Thank you in advance
On many reports I have optional parameters, for example if the employee is filled in it will run for that employee but if it's null it runs for all employees. Which is the best way to handle this?
The two options I am currently looking at are:
select * from employee where (employee.id = @EmpID or @EmpID is Null)
select * from employee where isnull(@empID, employee.id) = employee.id
Anyone else have a different solution?
Currently we use the OR approach and I wanted to see if anyone had any thoughts before switching to using IsNull, which seems a bit better.
Can I create a report that offers users a choice for the parameter. I want to show a sales report based on either Fiscal year or Calender Year. Can I do that with one report that allows an option on which parameter to choose or do I need two reports.
I am using Oracle 7.3 against SSRS. I have created an inline query with 7 unnamed parameters. I have named them in SSRS parameters window and selected NULL and ALLOW BLANK check boxes for all the parameters.
a.) What I think should happen is: I should be able to pass the combination of parameters NOT all of them, because I have selected NULL and Blank check boxes. But in my case the query is not giving me any results if I pass 2 of 7 parameters. I can see the results only when I pass all 7 parameters.
Please Help me...
b.) Is there a way I can create a Dynamic WHERE condition using ORACLE 7.3 as database and OUT REF cursor as out parameter for generating parameters. An Example would be great.......
I am much familar with SQL Server and creting a dynamic query is no problem. Because of this new assignment in Oracle 7.3 I am pulling my hair to solve this perticlaur problem...
hi all, I am using SQL reporting services 2005, i like to have a parameter as optional, is there is any diresct way to set a parameter as optional without setting through the default value.
I'm rewriting a T-SQL function that is called "Proper Case" which takes in a sentence and returns the sentence with the first letter of each word capitalized.
The new CLR(C#) function implements new functionality where it can take a string and turn it into a properly cased string, sentence cased string, lower cased, upper cased, and toggle cased.
The function takes in one parameter, the string, and the casing type, a string also. I want the casing type to be optional where if it's not passed in it defaults to "proper". The reason why I want this is so that I can easily replace the existing T-SQL function without having to add an extra parameter to each call to make life easier.
I know you can do it for SQL stored procedures, but I seem to be having trouble with the function.
Things I've tried: 1) Overloading the function in C# doesn't work because SQL functions don't like overloaded functions.
2) Attempting to set a "default" value to the parameter. a) casingType nvarchar(4000) = 'proper' b) default casingType nvarchar(4000) = 'proper'
Is there a way to create optional parameters in Reporting. For example, I have two tables Region and Country, with drop downs in report displaying the list of each. The stored proc for Country list expects an input parameter RegionID but does NOT require one for the result set to be fetched. The stored procs run fine in sql, but when run with the report, the designer always complains that the RegionID Parameter must be provided for the Country DataSet/List to be populated. Is there a way to create this RegionID parameter as optional such that the country list is populated with all rows in the Country table if no RegionId is provided, and filters if a RegionId is provided??
here is some code that I am using my stored procs
Code Snippet For Regions SP1 Create Proc... spGetRegions Begin...
Select RegionID, RegionName From Region
Order By RegionName End
Code Snippet
For Countries
SP2
Create Procedure dbo.spGetCountries
@RegionID int = NULL,
AS

Select CountryID, CountryName From Country C
WHERE C.RegionID = CASE WHEN @RegionID is null THEN C.RegionID ELSE
Hi I have a textbox, and a dropdown list, What i am trying to do is give the user the option of searching based on both (textbox and dropdownlist) or one or the other(textbox or dropdownlist), What i am experiencing though is that when i enter a word into the textbox and select a value from a dropdownlist i get no search results even though the word is "like" the text in the database, it will only work when i type out the full word. What is wrong with my stored procedure, here it is;
SELECT S.storeID, S.storeName FROM dbo.Stores AS SINNER JOIN dbo.storeCategories AS SC ON S.storeID = SC.storeID left JOIN dbo.SubCategories AS SU ON SC.subCategoryID = SU.subCategoryID WHERE S.storeName like ISNULL(@storeName + '%', S.storeName) AND SU.subCategoryID = ISNULL( @subCategoryID, SU.subCategoryID)
Hello Group I am having a little trouble with a search. I have 12 checkbox controls and 12 textbox controls. I want to be able to choose which textbox to query from. Most of the time the search may be from one or a couple of textboxes. My problem is I can get the SQL String right. Below is what I have for a string. I know I could write an SQL string for every possible combination and put in all 144 in a SELECT CASE, but I would think there is an easier way to do this. Is there anything that would let me build a SQL string depending what checkbox are checked true?

Hi, I'm having some issues with the SqlDataSource. I want to use it to populate a GridView, but using an optional parameter to filter the results.
This is what I have right now (hopefully haven't made any typos - can't copy/paste):
<asp:SqlDataSource ID="test1" runat="server" SelectCommand="SELECT * FROM SomeTable WHERE (@MyParam IS NULL OR MyColumn = @MyParam) ORDER BY SomeColumn" ConnectionString="<% ConnectionStrings:MyConnString %>" > <SelectParameters>
When I test the SQL query in the query designer it works (returns only rows having the value passed as a parameter when one is specified, otherwise it returns all rows), so it seems like that part is OK. The "All" (as in "return all"/no filtering) entry in the DropDownList has a value of a zero lenght string, and the ControlParameter has the convert empty string to null to true (and the default value is the same), so it should get converted to a null when "All" is selected, hence returning all rows. But it doesn't work. It works fine for all the entries with text, but the zero lenght string somehow doesn't work - I get no results at all instead of it returning all rows (but the query itself worked fine when I tested it).
What am I missing? I just can't find what I'm doing wrong. Any ideas/hints? (I also need to do the same with an ObjectDataSource, so hopefully I can get this to work!) I can't think of an easy way to find out if the zero lenght string gets converted to a null or not (I've even tried adding OR @MyParam = '' to the query and it still didn't work....) Right now I'm stuck....
