Optional Where Clause

Apr 17, 2008

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.

Stored Procedure With Optional/dynamic Where Clause

Apr 21, 2006

If I do this with a function and multiple inline sql statements, I could probably do it much easier, but here at work, sprocs are required, and I can't seem to stretch my knowledge and Google searches far enough to find the answer. Plus, I don't really think that creating 4 separate sProcs is the most efficient way of doing this
I need to select and return 8 columns from a table, but the problem is I need to feed the sProc parameters in such a way, that I can use different criteria in the Where Clause.
for instance, I need to combine these 4 select statements into one:1. Select (fields) from (table) Where TechID=@TechID and Status=@Status)2. Select (fields) from (table) Where TechID=@TechID3. Select (fields) from (table) Where OrdNum=@OrdNum3. Select (fields) from (table) Where CustNum=@CustNum
In all instances, the fields and the table are the same - how can I combine all these possible Where clauses (if/then - Select Case?) so that it's only one Stored Procedure?
(or, is this even possible?)

Transact SQL :: How To Create UNION Clause With Two Queries That BOTH Have WHERE Clause

Nov 4, 2015

I have a quite big SQL query which would be nice to be used using UNION betweern two Select and Where clauses. I noticed that if both Select clauses have Where part between UNION other is ignored. How can I prevent this?

I found a article in StackOverflow saying that if UNION has e.g. two Selects with Where conditions other one will not work. [URL] ....

I have installed SQL Server 2014 and I tried to use tricks mentioned in StackOverflow's article but couldn't succeeded.

Any example how to write two Selects with own Where clauses and those Selects are joined with UNION?

Optional Relationship

Dec 18, 2006

Hi, how can i make optional relationship?
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.

Optional Inner Joins

Nov 27, 2004

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.

Optional Critera

May 5, 2004

I have a SP with many parameters. If not supplied, parameter default value is NULL.

The parameters are to be used in the WHERE clause:

ALTER PROCEDURE dbo.SearchFlight

(
@DepartureDate datetime = null,
@ReturnDate datetime= null,
@MaxPrice money= null,
@Country int= null,

)

AS
SELECT *
FROM myTables with joint
WHERE
DepartureDate = @DepartureDate
AND ReturnDate = @ReturnDate
AND MaxPrice = @MaxPrice
AND Country = @Country

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 ther a solution ? using Case statement ???

Thanks for your help

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 %)

Optional Package Run In DTS

Jul 20, 2007

Hello everyone.



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.



DTSActiveScriptTask_3 (from above) --> success --> DTSExecutePackageTask_1 --> success --> DTSActiveScriptTask_4



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?

Use Of (optional) Keyword

Nov 26, 2007

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?

Thanks,

Normalize Your Database: NOT OPTIONAL!

Feb 28, 2004

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:

Optional Where In Stored Proc

Aug 5, 2005

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.

Optional WHERE In Stored Procedures

Aug 30, 2004

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

Dealing With Optional Variables

Jan 23, 2004

I'm looking for opinions here:

I have a stored procedure that has one required variable, and two optional variables, like this:

CREATE PROCEDURE sp_tariff_rule
@tariff_id INT,
@start_date DATETIME = NULL,
@end_date DATETIME = NULL
...etc...

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.

Dynamic Optional Parameters

Feb 13, 2008

Good day,

I have an issue on constructing dynamic WHERE conditions that use OPTIONAL parameters.

SP_SOMETHING (
1) @DateFrom datetime,
@DateTo datetime,
2) @Param1 char(8),
3) @Param2 char(3),
4) @Param3 tinyint
)

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.

thank you

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

Handling Optional Parameters

Jul 27, 2007

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.

Optional OLEDB Parameters : Need Help

Nov 8, 2007

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...

CLR Functions With Optional Parameters

Jul 28, 2006

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'

Any ideas would be greatly appreciated. Thanks!

Optional Report Parameters

Jun 11, 2007

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

Begin

Select CountryID, CountryName From Country C

WHERE C.RegionID = CASE WHEN @RegionID is null THEN C.RegionID ELSE

@RegionID END

ORDER BY C.CountryName

SQL Query Multiple/Optional Feilds

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?


Dim SQL_SL As String = "SELECT * FROM BuildZone" & _

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....

(Also posted this question on microsoft.public.dotnet.framework.adonet newsgroup)

Thanks a lot in advance for the
replies!
