SQL Query Multiple/Optional Feilds

Dec 3, 2004

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?








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


" WHERE Parcel = '" & strPercelS & "'" & _


" ORDER BY Parcel Asc" & _


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


" WHERE fldNameLast = '" & strNameLastS & "'" & _


" UNION" & _


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


" WHERE fldDateMonth = " & intDateYearS & "" & _


" AND fldDateYear = " & intDateYearS & "" & _


" UNION" & _


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


" WHERE fldNameLast = '" & strNameLastS & "'" & _


" UNION" & _


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


" WHERE fldPermitNum = " & intPermitS & "" & _


" UNION" & _


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


" WHERE fldStructureType = " & intStructureTypeS & "" & _


" UNION" & _


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


" WHERE fldConstructionCost >= " & intCCost1S & "" & _


" AND fldConstructionCost <= " & intCCost2S & "" & _


" UNION" & _


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


" WHERE fldRange = " & intRangeS & "" & _


" AND fldTownship = " & intTownshipS & "" & _


" AND fldSection = " & intSectionS & "" & _


" UNION" & _


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


" WHERE fldZoningDistricts = " & intZoneS & "" & _


" UNION" & _


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


" WHERE fldTwsp = " & intTwspS & "" & _


" UNION" & _


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


" WHERE fldRWD = " & intRWDS & "" & _


" UNION" & _


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


" WHERE fldWW = " & intWWS & "" & _


" UNION" & _


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


" WHERE fldAccessApplic = " & intAccessAppS & ""

Search Query With Optional Parameters

Jun 12, 2006

I need to create a stored procedure that will search some tables.

The stored procedure will be passed some parameters that may or may not have a value.

I have googled the best way to do this.
I found this post as an example: Optional Search Parameters

and also found this example : Optional Parameters in T-sQL

I am trying to figure out the best way to do this.

In the past I would build a dynamic query like the following.


SQL Code:






Original
- SQL Code




CREATE PROCEDURE [dbo].[Search_Results]

@SUBCITY VarChar(100) = 'Any'

AS

------------------------------------------------------------------------------------------------------
Declare @SUBCITYString Varchar(200)
If @SUBCITY <> 'Any'
Begin
Set @SUBCITYString = ' AND (Table1.SUBCITY LIKE ''' + @SUBCITY + '%'') '
End
Else
Begin
Set @SUBCITYString = ''
End
-----------------------------------------------------------------------------------------------------

Declare @SQLString As Varchar(500)
Set @SQLString = 'SELECT*

FROMTable1

WHERE Table1.ID IS NOT NULL
' + @SUBCITYString + '

ORDER BY Column ASC'

Execute (@SQLString)

GO






CREATE PROCEDURE [dbo].[Search_Results]  @SUBCITY VarChar(100) = 'Any' AS ------------------------------------------------------------------------------------------------------DECLARE @SUBCITYString Varchar(200)IF @SUBCITY <> 'Any' BEGIN  SET @SUBCITYString = ' AND (Table1.SUBCITY  LIKE ''' + @SUBCITY + '%'') 'ENDELSE BEGIN SET @SUBCITYString = '' END----------------------------------------------------------------------------------------------------- DECLARE @SQLString AS Varchar(500)SET @SQLString = '  SELECT    *                            FROM  Table1               WHERE  Table1.ID IS NOT NULL                ' + @SUBCITYString +  '            ORDER BY Column ASC' Execute (@SQLString) GO


However this is really cumbersome to create and is not fun debugging!

Does one of these ways have an advantage over the other? Or is there another way to do this?

Thank you!

Help With Optional Parameter Query With IN Statements

Aug 24, 2007

I have a query with 17 separate, optional, parameters. I have declared each parameter = NULL so that I can test for NULL in the case that the user didn€™t not pass in the parameter.

I am new enough to SQL Server that I am having difficulty building the WHERE clause with all of these optional parameters.

One solution I was advised on by a well paid SQL programmer, was to use a string in the stored proc and dynamically build the WHERE clause and exec it at the end of the sp. But the whole point of a stored proc is that it can be compiled and cached to make it faster, yet the string approach makes it have to compile every time it€™s run! Not a good solution, but maybe it€™s the best I can do . . .

I have tried many different approaches using different functions, etc. but I€™ve hit a brick wall. Any help in sorting it out with YOUR techniques would be greatly appreciated:

1. To add the parameter to the WHERE clause and test for NULL I€™ve used the COALESCE function such as €œWHERE table.fieldname = COALESCE(@Param, table.fieldname)€?. This works well if there is only one item in the parameter, but in the case that I pass multiple items to the parameter, it completely fails.

2. To handle multiple items, for example, if @Param = €˜3,7,98€™ (essentially, a csv separated list of keys)

Code SnippetWHERE table.fieldname IN(COALESCE(@Param, table.fieldname))


doesn€™t work because @Param needs to be parsed from a string into an array of integers in the parameter. So, I am using a UDF I discovered to parse the multi-item parameter. The UDF can be found at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnsqlmag01/html/TreatYourself.asp and it returns a table variable that can be used in an IN statement. So I€™m using


Code SnippetISNULL(table.fieldname, 0) IN (SELECT value FROM dbo.fn_Split(@Param,€™,€™))



which works brilliantly in my WHERE statement AS LONG AS @Param ISN€™T NULL. So how do I test for NULL first and still use this approach to multi-item parameters?

I€™ve tried


Code SnippetWHERE @Param IS NULL OR ISNULL(table.fieldname, 0) IN (SELECT value FROM dbo.fn_Split(@Param,€™,€™))


and though it works, the OR causes it to slow way down as it compares every record for the OR. (It slows down by approximately 800%.) The other thing I tried was


Code SnippetISNULL (table.fieldname, 0) IN (CASE WHEN @Param IS NULL THEN ISNULL(table.fieldname, 0) ELSE (SELECT value FROM dbo.fn_Split(@Param,€™,€™)))



This fails with €œSubquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression€? due to the multiple values in the parameter. (I can€™t understand why the line without the CASE statement works, but the CASE line doesn€™t!)

Am I even on the right track, cuz this is driving me mad and I just need a way to deal with optional multi-item parameters in an IN statement? HELP!

How To Get Relation Between Two Feilds Of Same Table

Apr 18, 2007

Hi,
I am new to sql and is working with sql server managment 2005 +c# 2005.

My application needs to create a blockdiagram sort of thing say
if in my database i got a table 'Addition' with 'a', 'b', 'c',and the primary key addition_id, and c is related to a and b as c = a+ b.

there is stored procedure name usp_addition which contains this relation. Each time any insert or update is done this sp is executed and all the values are updated for accordingly.
My problem starts in the front end where i need to draw the graphical representation of table addition.

In this graphical representation, I need to draw the labels a, b, c and the arrows from a and b which will connect to c, showing that c has a, b as inputs.

I got the label using dataset and datacolumns but hte problem is how to create the arrows the name of labels (i.e my column names from which the arrow should start and end)

How does I get the information that c as two inputs a, b. I dont need the values since i just want to view the columns in table and which column is input to another column.


Since I need to do this dynamically because my tablename, and the number and name of column would differ does any body knows how to do this.

Select Distinct One Some Fields, But Return All Feilds

Jul 23, 2005

I was curious...Is there a way to select distinct on a combination of some fields andthe for each record returned also get the other fields of anarbitrarily chosen record matching the fields in the distinct record.For example, if I have a select distinct on say three fields:SELECT DISTINCT Code1, Code2, Code3but the table also has other fields, maybe Foo1 and Foo2, and I wantFoo1 and Foo2 to also be displayed. Since there may be multiplerecords that match a particular Code1, Code2, Code3, then I just wantone of those to be arbitrarily chosen.

One Receipt Number, Query Multiple Tables Gives Multiple Data.

Sep 8, 2006

I have just taken over the job of sorting out a rather poorly designed database. It looks like it was 'upsized' from an access database to the SQL server. The SQL server is the 2000 version.

Now I am trying to generate a report of what the students in the database are owing by referencing the Receipt table and then all the available payment methods and allocations. I was wondering if there was anyway to work out data being displayed twice (Let me demonstrate)

Note1: All the tables are linked by a key of ReceiptNo. From what I can see there is a table for every payment type and allocation but no link between the two other then the receipt number.

Using the query:
SELECT T_Receipt.ReceiptNo, T_cheque.Amount AS Chq_Amount, T_credit.Amount AS Cre_Amount, StandingOrder.Amount AS Stn_Amount,
T_BankTransfer.amount AS Bnk_Amount, T_cash.TotalAmount AS Cas_Amount, T_RentPayment.AmountPayed AS Ren_Paid,
T_AdminPayment.AmountPaid AS Adm_Paid, T_InternetBilling.Total AS Int_Paid, T_Utilities.AmountPaid AS Util_Amount,
T_InvoicePayment.amountPaid AS Inv_Paid, T_OtherPayments.paymentAmount AS Oth_Paid, T_parkingBill.paymentAmount AS Prk_Paid,
T_TelephoneBills.TelephoneCredit AS Tel_Paid, T_DepositPayment.[Deposit payment] AS Dep_Amount, T_Receipt.cancelled AS Canceled,
T_Receipt.RemittanceReceiptNo AS Rec_Ref, T_Receipt.Student
FROM T_Receipt INNER JOIN
T_DepositPayment ON T_Receipt.ReceiptNo = T_DepositPayment.receiptNo LEFT OUTER JOIN
T_RentPayment ON T_Receipt.ReceiptNo = T_RentPayment.RentPaymentNo LEFT OUTER JOIN
StandingOrder ON T_Receipt.ReceiptNo = StandingOrder.ReceiptNo LEFT OUTER JOIN
T_TelephoneBills ON T_Receipt.ReceiptNo = T_TelephoneBills.ReceiptNo LEFT OUTER JOIN
T_parkingBill ON T_Receipt.ReceiptNo = T_parkingBill.ReceiptNo LEFT OUTER JOIN
T_OtherPayments ON T_Receipt.ReceiptNo = T_OtherPayments.ReceiptNo LEFT OUTER JOIN
T_InvoicePayment ON T_Receipt.ReceiptNo = T_InvoicePayment.receiptNo LEFT OUTER JOIN
T_cash ON T_Receipt.ReceiptNo = T_cash.ReceiptNo LEFT OUTER JOIN
T_AdminPayment ON T_Receipt.ReceiptNo = T_AdminPayment.ReceiptNo LEFT OUTER JOIN
T_BankTransfer ON T_Receipt.ReceiptNo = T_BankTransfer.receiptNo LEFT OUTER JOIN
T_Utilities ON T_Receipt.ReceiptNo = T_Utilities.receiptNo LEFT OUTER JOIN
T_credit ON T_Receipt.ReceiptNo = T_credit.ReceiptNo LEFT OUTER JOIN
T_cheque ON T_Receipt.ReceiptNo = T_cheque.ReceiptNo LEFT OUTER JOIN
T_InternetBilling ON T_Receipt.ReceiptNo = T_InternetBilling.ReceiptNo
GROUP BY T_Receipt.Student, T_Receipt.ReceiptNo, T_cheque.Amount, T_credit.Amount, StandingOrder.Amount, T_BankTransfer.amount, T_cash.TotalAmount,
T_AdminPayment.AmountPaid, T_InternetBilling.Total, T_Utilities.AmountPaid, T_InvoicePayment.amountPaid, T_OtherPayments.paymentAmount,
T_parkingBill.paymentAmount, T_TelephoneBills.TelephoneCredit, T_Receipt.cancelled, T_Receipt.RemittanceReceiptNo,
T_DepositPayment.[Deposit payment], T_RentPayment.AmountPayed, T_Receipt.Student
HAVING (T_Receipt.Student LIKE N'06%')

Which gives a result of:




RecNo.
30429
Cheque
250
Deposit
250


30429
679.98
250


This is fine but when I do analysis on this it appears as though the student has paid two deposit payments. I was wondering with out querying each table independently from an application if there was a criteria to specify that I only get one deposit result.
So as such say, give me all the payments but I only want one result from the other tables. I though about discrete but that wouldn't work here.

Query Help: Multiple WHERE, Multiple COUNT?

Mar 17, 2006

Howdy folks. I have a SELECT question for you. Or maybe a WHERE question. That I am not sure is part of the problem. My application is ASP.NET 2.0, and I’d like to avoid getting into stored procedures right now, if I could.
 
I am trying to summarize the order status for each customer in the database (SQL Server 2005, by the way). I want to provide two counts: the number of open jobs per customer, and the number of rush jobs per customer. Something like this:
 
CustID     CustName     JobOpen     JobRush
----------------------------------------------------------------
22            John Deere     47                3
24            MCP              32                 7
37            BlueON          6                  0
 
In my noobness, I developed this:
 
SELECT   CustID, MAX(CustName) AS CustName,
                  COUNT (*) AS JobOpen
FROM   Customers
INNER JOIN   Jobs ON JobCustID = CustID
WHERE   (JobDone = 0)
GROUP BY CustID
 
As you can see, it finds from the Jobs table all jobs that are not done (JobDone is a T/F field), joins the Jobs and Customers tables, groups by CustID, and counts the totals in each CustID group. It works great in outputting the first three columns that I am looking for.
 
But I cannot come up with a simple way to add JobRush (also a T/F field), because it needs a different WHERE clause than the one JobOpen uses. It would need
 
WHERE (JobRush = 1)
 
So maybe my question should be: how do I use multiple WHERE clauses, each with its own COUNT?
 
I did mess around with Common Table Expressions, and managed to build two CTEs (one with JobOpen results and the other with JobRush results) that I joined together. It worked in Studio Manager, but my ASP.NET page didn’t like it. I guess that means I could learn stored procedures, but wow I’d love to just have a nice complete SELECT command for my page.
 
Thanks for reading all this. Any input is greatly appreciated.
Matt

SQL Server Admin 2014 :: Estimated Query Plan For A Stored Procedure With Multiple Query Statements

Oct 30, 2015

When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.

1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?

<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>

2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?

SP To Perform Query Based On Multiple Rows From Another Query's Result Set

Nov 7, 2007

I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w.  one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included)         INSERT INTO @users             SELECT u.userName,u.userID                 FROM  tableU u                LEFT JOIN tableW w ON w.workgroupID = u.workgroupID                WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is:             SELECT u.userName,u.userID
                FROM  tableU u
                LEFT JOIN tableW w ON w.workgroupID = u.workgroupID
                WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!

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

Is it possible to define optional parameters for a stored procedure?

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

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,
-Q

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.

Query Within Query - Checking For Multiple Fields

Jun 9, 2008

Hi,
I remember seeing a fancy query that checked for multiple fields in a table (I think using a select statement in the where clause but not sure), but can't remember how to do it... here is what I want to do (and maybe there is a much easier way). Thanks!

Table1
id item color
1 shoe red
2 shoe blue
3 coat green
4 coat black

Table2
item color
shoe red
coat green

I want everything in Table1 where item and color are not a match.

So my results should be:
2 shoe blue
4 coat black

I'm sorry if this is a dumb question... it's been that kind of a day!

Thanks!

SPROC With Optional Parameter

Jan 16, 2004

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.

Thanks for any help,

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
