Ok, so i have this program, and at the moment, it generates an sql statement based on an array of db fields, and an array of values...
my question is this, is there any way to create a stored procedure that has multiple dynamic colums, where the amount of colums could change based on how many are in the array, and therefore passed by parameters...
if this is possible, is it then better the pass both columns and values as parameters, (some have over 50 columns)...or just create a seperate stored procedure for each scenario?? i have no worked out how many this could be, but there is 6 different arrays of colums, 3 possible methods (update, insert and select), and 2 options for each of those 24...so possibly upto 48 stored procs...
this post has just realised how deep in im getting. i might just leave it as it is, and have it done in my application...
but my original question stands, is there any way to add a dynamic colums to a stored proc, but there could be a different number of colums to update or insert into, depending on an array??
Cheers,
Justin

Hi,
I would like to add custom paging to my ASP.Net pages. How can I use Count(*) in a query such as below to retrieve a record count?
set ANSI_NULLS ONset QUOTED_IDENTIFIER ONGO
ALTER PROCEDURE [dbo].[view_icon_photos] @Filenumber int = '0' , @Location nvarchar(50)= '-1' , @Rubric nvarchar(MAX)= '-1' , @Author nvarchar(75)= '-1' , @startRowIndex int= '-1' , @maximumRows int= '0'
As
IF @Filenumber = '0' AND @location > '-1' AND @Rubric = '-1' AND @Author = '-1' AND @startRowIndex > '-1' AND @maximumRows >'0'Select Icon, Filenumber, RowRankFrom(Select Icon, Filenumber, Row_Number () Over ( Order By Filenumber ASC ) AS RowRankFrom dbo.photosWhere Location = @Location)As IconRank Where RowRank > @startRowIndex AND RowRank <= (@startRowIndex + @maximumRows)

hello,
i have a list of Categories and each one contains a list of SubCategories, and i use a nested Repeater to show each Category with their SubCategories, but because are to many to show verticaly, i want to make 2 nested repeaters and in the first one to show only the first "n" Categories with their SubCategories and in the second Repeater should be the last n Categories, and like so they will be in 2 colums
How can i use the COUNT function in my stored procedure to take only first n Categories?
I used SELECT * FROM Categories WHERE CategoryID <= 5 but i don't want to order by the primary key i want to order by a COUNT or something like this...
here is my stored procedure (i use it for two nested Repeaters)ALTER PROCEDURE SubCategoriiInCategorii
CategoryID int)
AS
SELECT CategoryID, Name, Description FROM Categories WHERE CategoryID = @CategoryIDORDER BY Name
SELECT p.SubCategoryID, p.Name,p.CategoryID FROM SubCategorii p
ORDER BY p.Name
i hope you understand what i mean, thank you

what's wrong with the following code? COUNT for completed and exempted doesn't return correct values. they return same values. but when i remove one count it's returning right COUNT. i need to return the COUNT from two tables with a single query. how can i accomplish that??? is there anything wrong with my code below?
<code>
CREATE PROCEDURE dbo.Test AsSELECT s.StudentIdNum, c.[Name], COUNT(*) AS Completed, COUNT(*) AS exempted FROM StudentEnrolled AS s JOIN StudentCourse AS sc ON s.StudentKey = sc.StudentKey JOIN Courses AS c ON sc.CourseID = c.CourseIDLEFT JOIN ModuleEnrolment AS m ON sc.StudentCourseID = m.StudentCourseIDLEFT JOIN ModuleExemption AS e ON sc.StudentCourseID = e.StudentCourseIDWHERE m.Status = "Completed"GROUP BY s.StudentIdNum, c.[Name]
</code>

Hi all,
I have a web application that has a search engine that returns records based off what the user selects in the search engine. I am currently using coalesce in the where statement in my stored procedure to return the records. For eample,
where field1= coalesce(@parm1,field1). I don't know if this example is better than building the sql statement dynamically in a parameter then executing the parameter with sp_executesql. Can someone explain to me which is better or if there is a better solution?
Thanks,
James

CREATE PROCEDURE ggg_test_sp
@start_date datetime,@end_Date datetime
AS
SET NOCOUNT ON
DECLARE @sqlstmt varchar(1000)
SELECT @sqlstmt='SELECT * FROM ggg_emp WHERE date_join BETWEEN ' +CONVERT(varchar(10),@start_date-1,101) + ' AND ' +CONVERT(varchar(10),@end_Date+1,101)
SELECT @sqlstmt
EXEC (@sqlstmt)
GO
I want to apply date filter in the above sp with dynamic sql stmt. When i execute the above procedure with date ranges( @start_date=07/06/2004 AND @end_Date= 08/06/2004)i am not getting any result because my @sqlstmt variable has the select stamet
SELECT * FROM ggg_emp WHERE date_join BETWEEN 07/06/2004 AND 08/06/2004
BUT it should have the sqlstmt as
SELECT * FROM ggg_emp WHERE date_join BETWEEN '07/06/2004' AND '08/06/2004' to produce the required result
I know that for the above SP we dont need any dynamic sql but this is just an example.
So anyone can help me on this issue.
Thanks.

Can anyone help me with this dumb question?
I want to use a stored procedure to bring back a recordset depending if a bit column is set to 1. My table has a number of columns that are of Data Type bit and I want to be able to specify which particular column I'm interested in as a parameter when I call the Stored Procedure.
I have set up the Stored Procedure as follows:
CREATE PROCEDURE getProducts
@param1 varchar(50)
AS
SELECT ProductID, ProductName
FROM dbo.Products
WHERE @param1 = '1'
GO
I'm calling it like this:
Dim cmdX, cmdParam, rsX
cmdParam = "OnSpecial"
set cmdX = Server.CreateObject("ADODB.Command")
cmdX.ActiveConnection = conn_STRING
cmdX.CommandText = "dbo.getProducts"
cmdX.Parameters.Append cmdX.CreateParameter("@RETURN_VALUE", 3, 4)
cmdX.Parameters.Append cmdX.CreateParameter("@param1", 200, 1,50,cmdParam)
cmdX.CommandType = 4
cmdX.CommandTimeout = 0
cmdX.Prepared = true
set rsX = cmdX.Execute
rsX_numRows = 0
I know for a fact that I have products in my dbase with the bit column 'OnSpecial' set to 1, yet no records are coming back.
Any pointers would be most appreciated.

We are continuing to have issues with a certain stored procedure using dynamic sql. The issue arose when we tried to clean the stored procedure up, and seemed to have zero problems in staging. As soon as we moved it into production, the stored proc caused excessive blocking and completely slowed down our production environment. We immediately rolled back the older version and production is back to normal.
After looking at the new procedure I don't understand how it could cause blocking. Any help is much appreciated!
Old Proc without issues----

Description:
Does a lookup of MLS Property data for reverse link. This is susceptible to error in that if erroneous data is given
to us,it will not find a match. For this reason, commented out the lookup on Suffix and changed the street
to use a like clause. Many users are putting the suffix in the street clause and no hits are generated.
This hurts performance, but it improves the hit ratio.

I have the following for sql server 2000...
Select b.courseName, a.courseId, count(a.courseId) as [count], avg(convert(INT, a.fldScore)) as [average], count(fldPass) as [passed], count(fldPass) as [failed] From tblTest a inner join tblTest2 b on a.courseId = b.courseId Group by a.courseId, b.courseName
Problem is the [passed] and [failed]
As it is, it's counting all of them.
I need to adjust it so passed will only read where fldPass = 'yes'
and fldPass = 'no' for the passed and failed.
Suggestions?
Thanks,

I am trying to determine the number of columns that are returned froma stored procedure using TSQL. I have a situation where users will becreating their own procedures of which I need to call and place thoseresults in a temp table. I will not be able to modify those usersprocedures. I figure if I have the number of columns I can dynamicallycreate a temp table with the same number of columns, at which point Ican then perform an INSERT INTO #TempTableCreatedDynamically EXEC@UserProcCalled. With that said, does anyone have any idea how todetermine the number of rows that an SP will return in TSQL?Thanks!

Okay, I have sort of a peculiar permissions question I am wondering if someone can help me with. Basically, here's the scenario...
I have a CLR stored procedure which does some dynamic SQL building based on values sent in via XML. It's a CLR stored procedure using XML because I want to build a parameterized statement (to guard against SQL Injection) based on a flexible number of parameters which are basically passed in the XML.
The dynamic SQL ends up reading from a table I'll call TableX and I actually discovered an (understandable) quirk with security.
Basically, the connection context is using security for a low-privilaged Windows account ("UserX") and UserX has no permission to the table referenced in the dynamic SQL but because of the dyanmic nature of the query, the stored procedure ends up adopting the security context of UserX. Naturally, this throws a security exception saying UserX has no SELECT permission on TableX.
Now, I can give UserX read permission to the table in question to get things running, but one of the points of using stored procedures is to defer security to the procedure level vs. configuration for tables or columns.
So in striving toward my ideal of security at the procedure level, my question is what is the best way to allow minimum privilege in this case?
I thought about having the internals of the CLR stored procedure run under a different (low-privalaged) security context, but I am wondering if there's an alternate configuration that may be as secure, but simpler.
PS - Please don't let this degenerate into a conversation about OR mappers. I know that happens a lot on these forums.

I am taking my first steps into stored procedures and I am working on a solution for efficiently paging large resultsets with SQL Server 2000 based on the example on 4Guys: http://www.4guysfromrolla.com/webtech/042606-1.shtml
The problem with my stored procedure is, is that it doesn't seem to recognize a variable (@First_Id) in my dynamic Sql. With this particular sproc I get the error message: "Must declare the scalar variable '@First_Id'"It seems to be a problem with 'scope', though I still can't yet figure out. Can anyone give me some hints on how to correctly implement the @First_Id in my stored procedure? Thanks in advance!
Here's the sproc:

Hi i am trying to make the "userName" section of the code below dynamic as well, how can i do this, the reason being userName will not always be passed through to it.
ALTER PROCEDURE [dbo].[stream_UserFind]
(
@userName varchar(100),
@subCategoryID INT,
@regionID INT
)ASdeclare @StaticStr nvarchar(5000)set @StaticStr = 'SELECT DISTINCT SubCategories.subCategoryID, SubCategories.subCategoryName,Users.userName ,UserSubCategories.userIDFROM Users INNER JOIN UserSubCategories ON Users.userID= UserSubCategories.userIDINNER JOINSubCategories ON UserSubCategories.subCategoryID = SubCategories.subCategoryID WHERE UserName like ' + char(39) + '%' + @UserName + '%' + char(39)
if(@subCategoryID <> 0) set @StaticStr = @StaticStr + ' and SubCategories.subCategoryID = ' + cast( @subCategoryID as varchar(10))if(@regionID <> 0) set @StaticStr = @StaticStr + ' and SubCategories.RegionId = ' + cast( @regionID as varchar(10))
print @StaticStr
exec(@StaticStr)

My existing ASP 1.0 site keeps getting hacked using SQL injections. I have rewritten the site in ASP 3.5 to stop the attacks but cannot figure out how to dynamically generate a basic keyword search.
I am trying to take the keywords entered into an array and then construct the WHERE clause - not having much luck. Getting either errors or double LIKE statements. Need some help.
string[] SqlKWSrch;
SqlSrch = KWordSrch.Text;SqlKWSrch = SqlSrch.Split(' ', ','); int AStop = SqlKWSrch.Length; int i = 0; foreach( string a in SqlKWSearch ) { if (i <= AStop) { SqlWHR = SqlWHR + "L_Kwords LIKE '%' + " + " '" + SqlKWSrch[i] + "' " + " + '%' AND "; } else { SqlWHR = SqlWHR + "L_Kwords LIKE '%' + " + " '" + SqlKWSrch[i] + "' " + " + '%' "; } i++; }
1) I can't seem to properly terminate the final LIKE statement2) can't figure out how to pass 'SqlWHR' to the procedure
GIVEN KEYWORDS: 'antique chairs' entered I want to end up with the below SP, the @SqlWHR parameter appeared to have worked once but it probably was an illusion.
PROCEDURE KeyWordSearch@SqlWHR varchar(100)AS
SELECT L_Name, L_City, L_State, L_Display FROM tblCompanies WHERE L_Kwords LIKE '%' + 'antique' + '%' AND L_Kwords LIKE '%' + 'chairs' + '%' AND L_Display = 1
RETURN
Thank you

Hi, I have a table with values such as test1, test2, test3, test4, test5.
I need to write a stored procedure with paramater (number TINYINT, number2 TINYINT), the number represents the field that I'm going to select and compare. For example if I pass in (1,5) I will need the fields test1 and test5 and store them in Temp and Temp2. How do I write the following to so it will dynamically select which field to use when passing the parameters?
DECLARE @Temp TINYINT,
DECLARE @Temp2 TINYINT,
SELECT top 1 Temp = test1, Temp2 = test5 from table

Hi all!
I need to create a stored procedure with a parameter and then send a WHERE clause to that parameter (fields in the clause may vary from time to time thats why I want to make it as dynamic as possible) and use it in the query like (or something like) this:
---------------------------------------------------
@crit varchar(100)
SELECT fldID, fldName FROM tblUsers
WHERE @crit
----------------------------------------------------
Of course this does not work, but I don't know how it should be done, could someone please point me in the right direction on how to do this kind of queries.
cheers!

I am trying to do something similar to the following where I want to perform dynamic ordering on two tables that have been unioned as shown below.
CREATE PROCEDURE procedure_name
@regNum varchar(14),
@sortOrder tinyint = 1
AS
SELECT Filler_OrdNum As 'Accession', RTrim(Obs_Code) As 'Observation', REG As 'Register',
Obs_Date As 'Observation Date'
FROM tblSPG_Header
WHERE
REG = @regNum
UNION
SELECT Filler_OrdNum As 'Accession', RTrim(Obs_Code) As 'Observation', REG As 'Register',
Obs_Date As 'Observation Date'
FROM tblRCH_Header
WHERE
REG = @regNum
ORDER BY Obs_Date DESC
GO
Note that I am only sorting on the Obs_Date column, but I'd like to be able to sort on any column within the selection list. I know that I need to use:
ORDER BY CASE WHEN @sortOrder = 1 THEN Obs_Date END DESC
but I frequently get the following error when I try to do so:
"ORDER BY items must appear in the select list if the statements contain a UNION operator"
If anyone can offer any suggestions, I would appreciate it. Thanks.

Hi, I have several parameters that I need to pass to stored procedure but sometimes some of them might be null. For example I might pass @Path, @Status, @Role etc. depending on the user. Now I wonder if I should use dynamic Where clause or should I use some kind of switch, maybe case and hardcode my where clause. I first created several stored procedures like Documents_GetByRole, Documents_GetByRoleByStatus ... and now I want to combine them into one SP. Which approach is better. Thanks for your help.

I create a stored procedure as following:
........
CREATE Procedure myAutoSearch
(
@Make varchar(50),
@Model varchar(50),
@AutoType varchar(50),
@Miles float,
@Zipcode varchar(5)
)
AS
DECLARE @RowCount int
SELECT @RowCount = Count(*) FROM ZIPCodes WHERE ZIPCode = @Zipcode AND CityType = 'D'
if @RowCount > 0
BEGIN
SELECT
z.ZIPCode, z.City, z.StateCode, a.Make, a.Model, a.AutoPrice, a.AutoPrice2, a.AutoYear,
a.Mileage, a.AdID, a.ImageURL, dbo.DistanceAssistant(z.Latitude,z.Longitude,r.Latitude,r.Longitude) As Distance
/*
The above functions requires the Distance Assistant.
*/
FROM
ZIPCodes z, RadiusAssistant(@ZIPCode,@Miles) r, AutoAd a
WHERE
z.Latitude <= r.MaxLat
AND z.Latitude >= r.MinLat
AND z.Longitude <= r.MaxLong
AND z.Longitude >= r.MinLong
AND z.CityType = 'D'
AND z.ZIPCodeType <> 'M'
AND z.ZIPCode = a.Zipcode
AND a.AdActive = '1'
AND a.AdExpiredate >= getdate()
AND a.Make = @Make
AND dbo.DistanceAssistant(z.Latitude,z.Longitude,r.Latitude,r.Longitude) <= @Miles
/*
The above functions requires the Distance Assistant.
Also note that SQL Server caches the results so that this and the "SELECT dbo.DistanceAssistant"
functions are both only computed once.
*/
ORDER BY Distance, Make
END
ELSE
SELECT -1 As ZIPCode
--ZIP Code not found...
....................
This stored procedure work very well.
The question is how I add some dynamic condition inside the where condition.
I want to add:
If @Model <> "See All Models"
AND a.Model = @Model'
If @AutoType <> "New/Used"
AND a.Condition = @AutoType
I try several ways, but fail.
If you know how to add these two dynamic parameters into the condition of stored procedure, please help.

Hi
I am in the very final stages of
building a dating app for a client, I am totally stuck with the
advanced search page. been googling for days with limited success
For the most basic of purposes I have added a few form fields to my search.aspx page;
county (Dropdown list)
min age (Dropdown list)
max age (dropdown list)
Smoker (check box)
keyword (textbox)
My codebehind passes the vars to a stored procedure
@county = me.county.selectedvalue
etc
My problem is the stored procedure I sort of have the following but I can't get it to run
<code>
ALTER PROCEDURE dbo.TEST_ADVANCED_SEARCH
(@countyID int ,
@MaxAge
varchar(100),
@MinAge
varchar(100),
@smoker tinyint),
@keyword
varchar(250))
AS
DECLARE @SQL Varchar
(4000)
SELECT @SQL = 'dbo.user_accounts.profileComplete,
dbo.user_accounts.countyID, dbo.user_profiles.smoker,
dbo.user_profiles.Age
FROM dbo.user_accounts INNER
JOIN
dbo.user_profiles ON dbo.user_accounts.userID =
dbo.user_profiles.userID
WHERE (dbo.user_accounts.profileComplete =
1)'
IF @countyID > 0
SELECT @SQL = @SQL + ' AND
(dbo.user_accounts.countyID = @countyID)'
IF @MaxAge IS NOT
NULL
SELECT @SQL = @SQL + ' AND (dbo.user_profiles.Age <= @MaxAge)
'
IF @MinAge IS NOT
NULL
SELECT @SQL = @SQL + ' AND (dbo.user_profiles.Age >= @MinAge)
'
IF @smoker > 0
SELECT @SQL = @SQL + ' AND
(dbo.user_profiles.smoker = 1)'
IF @keyword IS NOT
NULL
SELECT @SQL = @SQL + ' AND (dbo.user_profiles.Description LIKE @MinAge)
'
EXEC(@SQL)
</code>
If I can get this to work I can add the remaining fields that I need
Am I Missing something glaringly obvious?
Any help or advice gratefully received
Thanks

I have a stored procedure being called based on user search criteria. Some, the colour and vendor fields are optional in the search so i do not want that portion of the procedure to run.
at this point i keep getting errors in the section bolded below
it never seems to recognize anything after the if @myColours <> 'SelectAll'

Anyone know how i should word the if...statements?
I have not found anything that works yet.

Hello,
I have a stored procedur like this:
--------------------------------------------
ALTER PROCEDURE dbo.pdpd_DynamicCall
@SQLString varchar(4096) = null
AS
create TABLE #T1
( column_1 varchar(10) ,
column_2 varchar(100) )
insert into #T1
execute ('execute ' + @SQLString )
select * from #T1
--------------------------------------------
The problem is that I want to call different procedures that can give back different columns.
Therefor I would have to define the table #T1 generically.But I don't know how.
Can anyone help me on this problem?
thank you

I can't figure out why this won't work. I want to use a variable for the 'ORDER BY' in my Stored Procedure.
I use this to order my results by product price or alphabetically from a dropdown menu. I have tried the following, but get the error below.
Code:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER procedure [dbo].[SPResults]
[Code] ....
Code:
Msg 1008, Level 16, State 1, Procedure SPResults, Line 21
The SELECT item identified by the ORDER BY number 1 contains a variable as part of the expression identifying a column position. Variables are only allowed when ordering by an expression referencing a column name. Is this possible to do?

Hi
I have a small problem writing a stored procedure in a SQL Server 2000 database.
I would like to generate som part of the SQL inside this stored procedure that is used in an IN expression of my WHERE clause. There is no problem for me to generate a string containing my expression, the problem is that SQL-Server donīt generate a resulting SQL-statement.
Example:
CREATE PROCEDURE spDynStatement
AS
DECLARE @sPartOfSQLStatement NVARCHAR(100)
-- Some T-SQL that generates the dynamic part of the SQL-statement
-- .
-- .
-- .
-- As substitute I insert the string expression
SET @sPartOfSQLStatement = '''1''' + ', ' + '''1.5'''
-- SELECT @sPartOfSQLStatement results in: '1' , '1.5'
SELECT * FROM BBNOrganization WHERE OrgStructureID IN( @sPartOfSQLStatement ) -- does not work
SELECT * FROM BBNOrganization WHERE OrgStructureID IN( '1', '1.5' ) -- works!!!
GO
Thankfull for ideas on how to solve my problem,
Peter
