Best Way To Construct Dynamic Queries
Apr 17, 2008
I am working with a form that I wish to construct a dynamic query from the results of. The forum has a date range and two radio buttons. Each radio button enables a list of items that can be clicked. So for example, if we assume the question,
"What is your favorite food, and what toppings do you like on it?" where the radio buttons are foods, the list boxes are toppings. Assuming the user can choose a Hamburger or a Salad with generic toppings, their choices are as such:
They can choose a Hamburger, with every topping
They can choose a Hamburger with a single topping.
They can choose a Hamburger with multiple toppings.
They can choose a Salad with the same combinations as above.
They cannot choose both a Hamburger and a Salad - mutually exclusive items.
Then, I wish to construct a query that, based on the conditions above, retrieves information relavent to their criteria, such a the number of food items to choose from, their price, etc. - basic information. What is the most efficient way to do this? Should I write a stored procedure with numerous conditionals and all available parameters, constructing the sproc as such:
Code Snippet
CREATE PROCEDURE GetFoodInfo
@from datetime,
@to datetime,
@FoodType varchar(20),
@toppings varchar(20)
AS
BEGIN
DECLARE @query varchar(300)
SET @query = 'SELECT COUNT(DISTINCT ' + @FoodType + ') '
IF @FoodType = 'Hamburger'
SET @query = @query + 'FROM Hamburgers '
ELSE
SET @query = @query + 'FROM Salads '
IF @toppings <> 'ALL'
SET @query = @query ' WHERE Toppings = ' + @toppings
EXEC (@query)
Apologies of this syntax is incorrect, but you get the general idea. Of course, this is a small example - in reality, I would have 5-10 conditional requirements Or, should I generate a stored procedure (or simple query) for each operation? For example, assuming each is a stored procedure:
GetHamburgers <-- would get Hamburgers with all toppings
GetHamburgersWithToppings
GetSalads
GetSaladsWithToppings
What is the best method for what I wish to achieve? What is fastest? Is there a better way than I have listed? Thank you.
Again, this is a small example, but I hope someone can help.

My problem (excuse me for being a novice) is that whenever the query becomes complex
in the @whereclause (and it does) it cant exceed the character limit of a nvarchar. Now if someone could shed some ligfht on this for me I would be
incredibly grateful. I have tried doing the exec(@var1 + @var2) but this did not seem to work.
I have included the stored procedure below.
ALTER PROCEDURE [dbo].[SearchTenderMultiRegions]
(
@whereclause nVarChar(MAX), --4000 chars
@PageIndex int,
@PageSize int
) AS
SET NOCOUNT ON;DECLARE @sql nvarChar(MAX)
SET @sql= 'SELECT * FROM (SELECT DISTINCT TOP (' + CONVERT(nvarchar(10),(@PageIndex*@PageSize))
SET @sql= @sql + ') ROW_NUMBER() OVER (ORDER BY Tenders.ID DESC)AS Row,
Tenders.ID,Tenders.Title,Address.Suburb,Tenders.ClosingDateTime,Tenders.IsApproved,Tenders.TendersSourceID, Tenders.SourceDate,
UserTracking.CreateUserID,UserTracking.CreateDateTime FROM Tenders LEFT JOIN TenderContact ON Tenders.ID = TenderContact.TendersID
LEFT JOIN TenderCategory ON Tenders.ID = TenderCategory.TendersID
LEFT JOIN TenderRegion ON Tenders.ID = TenderRegion.TendersID
LEFT JOIN RegionStateCountry ON TenderRegion.RegionStateCountryID = RegionStateCountry.ID
LEFT JOIN Address ON Tenders.ID = Address.TendersID
LEFT JOIN UserTracking ON Tenders.ID = UserTracking.TendersID
WHERE '
SET @sql= @sql + @whereclause
SET @sql = @sql + ') as TenderSearchEntries
WHERE Row between ('
SET @sql= @sql + CONVERT(nvarchar(10), @PageIndex)
SET @sql= @sql + ' - 1) * '
SET @sql= @sql + CONVERT(nvarchar(10), @PageSize)
SET @sql= @sql + '+ 1 and '
SET @sql= @sql + CONVERT(nvarchar(10), @PageIndex)
SET @sql= @sql + ' * '
SET @sql= @sql + CONVERT(nvarchar(10), @PageSize)
EXEC(@sql)

Hi,
This question has been asked probably million times, but it sems that I cannod find right answer on search engines.
I need to send parameters to my stored procedure, but not only parameters. For example in where clause I have something like:
where myID = 12
I need to be able to filter results on myID, but one time I need it to be eqal to 12 and other time I need it to be different (<>) from 12. Some time I even need to add another condition like myID2 = 1. Can I solve this without additional procedures?
I believe that I saw solution in 3-Tier ArchitectureTutorial Series few weeks ago but it seems that something changed, and I cannot find it anymore. Can anyone help?

Hi,
I have a parameter in the url to the report. According to that parameter, I need to change the query. For example, url = http://localhost/reportserver?param1=A
if Param1=A, then I need to use query1 for the report
if param1 = B, then I need to use query2 for the report.
I would like to know if I can do this. If not, is there any other way to build query dynamically in the report.
thanks

I'm creating a search function right now and I'm running into a problem where my search function doesn't know what fields the user will search for, and therefore doesn't know whether or not to put quote marks around specific values or not.
For example, somebody might search for somebody else with year of birth in which case I might have a query:
SELECT userid FROM users WHERE yob = 1970
but somebody else might search for a name, in which case I need
SELECT userid FROM users WHERE first_name = 'Andrew'
or somebody else might search for both and need
SELECT userid FROM users WHERE yob = 1970 AND first_name = 'Andrew'
I'm accomplishing this by having the function (this is in PHP) take an array as an argument, where the key is the MySQL column and the value is the required value for that column. So in the 3rd example, it would be a 2-item array:
yob => 1970
first_name => 'Andrew'
And then cycling through that and dynamically creating a MySQL query based on the received array.
So... my problem is finding a way to specify when quote marks are required and when they're not. Is there any way to just have MySQL default to the format of the column? Also, if anybody thinks this isn't the right way to create a search function, let me know because I'm new at this .
Thanks!
PS: Right now what I'm doing is I'm creating arrays that include names of columns that do and don't need quote marks. Then in construcing the MySQL statement I'm checking to see which array a column is in, and making the quote decision based on that.

Hello, I really have a problem writing queries for the dynamic values. i follow the below mentioned method to write the queries but its really confusing. ex: str = "SELECT SO.Description,SO.DiscountPct,SO.Type,SO.Category,SO.StartDate,SO.EndDate,SO.MinQty,SO.MaxQty," + "S.Name AS ProductSubCategory,P.Name AS ProductName, C.Name AS ProductCategory FROM Production.Product P " + "INNER JOIN Production.ProductSubcategory S ON P.ProductSubcategoryID = S.ProductSubcategoryID " + "INNER JOIN Production.ProductCategory C ON S.ProductCategoryID = C.ProductCategoryID " + "INNER JOIN Sales.SpecialOfferProduct SOP ON P.ProductID = SOP.ProductID " + "INNER JOIN Sales.SpecialOffer SO ON SOP.SpecialOfferID = SO.SpecialOfferID " + "WHERE '" + txtStartDate.Text + "' between SO.StartDate AND SO.EndDate AND '" + txtEndDate.Text + "' BETWEEN SO.StartDate AND SO.EndDate " + "AND SO.Description Like '" + txtSpecialDesc.Text + "%'"; can anybody help me in writing the queries for dynamic values in an easy way.

Hello, I'm trying to create a Stored Procedure who receives the table name as a parameter, then uses a cursor to obtain every column name and then builds a string like SELECT col1, col2, ... from TABLE
In fact that would be the same as SELECT * FROM table; but I can't do this, because I'll be using this stored procedure to loop through many tables that has different quantity of columns with a DTS, and if a specify the *, then the DTS wouldn't let me do the select with tables with different quantity of fields.
Could you help me please, because my code isn't working:
CREATE PROCEDURE dbo.stp_Test
(
@tablename AS VARCHAR(50)
)
AS
DECLARE @columnname varchar(50)
DECLARE @strsql Nvarchar(500)
DECLARE @query varchar(4000)
SET NOCOUNT ON
DECLARE c1 CURSOR FOR
SELECT column_name FROM information_schema.columns
WHERE table_name = @tablename
OPEN c1
FETCH NEXT FROM c1 INTO @columnname
WHILE @@fetch_status = 0
BEGIN
IF (@strsql is null)
BEGIN
SET @strsql=@columnname
END
ELSE
BEGIN
SET @strsql = @strsql + ',' + @columnname
END
FETCH NEXT FROM c1 INTO @columnname
END
CLOSE c1
DEALLOCATE c1
SELECT @query = 'SELECT ' + @strsql + ' FROM ' + @tablename
EXEC @query

Hello, i have dynamic queries for example:
DECLARE @query nvarchar(250);
DECLARE @table nvarchar(100);
SET @table = 'table_name';
SET @query=
N'update '+@table+'
set column = 0
where column is null';
EXECUTE sp_executesql @query
SET @query=
N'update '+@table+'
set column2 = 0
where column2 is null';
EXECUTE sp_executesql @query
It is very simple example. My question is: it is possible somehow put these queries in SQL Tasks?
Because if i do like this i get error "The Declare cursor SQL construct or statement is not supported."
Maybe there is other way to solve my problem? Or maybe syntax should be changed?
Thanks for advice

Im reviewing my stored procedures for a new application and got to thinking about protecting against sql injection. I think im pretty safe since im using stored procedures and none of them use any 'exec' commands within them, but im not sure.
I was reading this article, and again all the examples that list a stored procedure, have an 'exec' command somewhere that is the culprit. So, in my case lets say I was doing something like this:
Im generally using regularexpression validation controls on the client side of the application and limiting the max length of the input there as well.
Am I safe, or do I need further input checking within the procedure ?
Code Snippet
CREATE PROCEDURE [dbo].[get_Uploads]
@app varchar(50)
--Init variables
SET @error_number = 0
BEGIN TRY
SELECT [Logid],[Filename],[Label],[UploadDate],[App]
FROM UploadLog au
WHERE [App]=@app
END TRY
BEGIN CATCH
SET @error_number = -2

I am a business user trying to build an incremental ETL package with SSIS. I have a working prototype on SQL Server 2005 where I select the max(ID) from the last successful run and pass that value into a variable. Then, in my Data Flow step, I select an OLE DB source adapter and use this variable in a custom select statement.
Here's my challenge....the live data is actually in a Postgres DB so I have to use a Data Reader Source adapter. When I try to pass my variable to this adapter the job bombs out. Does anyone know how to dynamically update the query text inside a Data Reader source adapter using variables or otherwise?

My head hurts...it might be an easy one for many people, but cant seem to figure a way to do it.Ok, I have a table with a field called Ad_Price. This field is a nvarchar one, theres many different value in it, all of them corresponding to a price. Now, what I want to do is only get the row that are not written in a good price format (like123$ is wrong, but 123.00 is good, but only value following this exemple)For exemple, if I have all these value145.876785.34654$45 to negociate1bvcaa0.01876.556the value I want to have are:654$45 to negociate1bvcaa876.556because they dont follow the format I wantso im not sure if my explication was clear enough..all in all what I want to complete is the WHERE part of my SQL instruction...what should I put in:SELECT *FROM AdsWHERE ???????thansk for taking the time to read this

I am using the following code to construct an SQL 7.0 View Column
"CASE WHEN [DailyHours] > SUM([TransAmt]) THEN 0 ELSE 1 END"
and it works great!!
However, when I try the same line in SQL 2000, I get the message "The query designer does not support the case SQL construct"
The help screen is no help as all it says is "the syntax you entered is valid but is not supported visually by Query Designer. Be sure the verify your syntax before saving."
It will not let me save, so I'm not sure what to do from here now????

Can you contruct a variable name from another variable? For example, I want the following to PRINT 10
DECLARE @var1 INT
DECLARE @var2 INT
SET @var1 = 10
SET @var2 = 20
PRINT '@var' + '1'
This prints the variable name, not the contents of the var. I tried to parse it with square brackets, but no luck.
Thanks,
Carl

Dear Group,
I'm upgrading a "classic" ASP app to ASP.NET 2.0. The database is stored on a SQL Server box in-house. I'm looking to inject a bit of flexibility into the SQLDataSource SelectCommand property.
What I mean is this: depending on a selection a user makes in the form, I'd like to present a GridView object that displays data filtered by the user's selection.
So I took the original long query string from ASP and broke it in two pieces. The first piece contains the bulk of the query and it ends just after the WHERE clause. The second piece is the ORDER BY clause. I'd like to have the ability to inject an additional term at the end of the WHERE clause (using AND). That would be the filter.
For example,SELECT LastName, FirstName, InOut, TimeEntered, PhoneExt
FROM TimeClock
WHERE TimeEntered > '6/17/2008'
AND EmploymentState > ''
ORDER BY LastName, FirstName
So, in between the "AND State > '' " and the ORDER BY clause I'd like to insert something like this:AND Department = 'Production'
I'd like the SelectCommand of the SQLDataSource to look like this:SelectCommand="<%= (sql1 & " AND Department = 'Production' " & sql2) %>"
sql1 and sql2 are defined in a <script runat="server"></script> block in the page <head>. The following errors occur even if I have a single variable containing the whole SQL query string (i.e., SelectCommand="<%= sql1 %>").
When I try to run the page I get this error:Exception Details: System.Data.SqlClient.SqlException: Line 1: Incorrect syntax near '<'.
If I remove the quotation marks from around the SelectCommand statement I get:Parser Error Message: Server tags cannot contain <% ... %> constructs.
What's funny about this is that the ConnectionString property of the SQLDataSource looks like this:ConnectionString="<%$ ConnectionStrings:PersonnelDatabaseConnectionString %>"
No complaints from the compiler about the ConnectionString.
Any ideas? Am I simply going to be unable to construct a SelectCommand on-the-fly?

Hi,I have three dropdown lists branch, month & year. Based on these I need to retrieve data in my Datagrid.I have written the following SQL statement & code in my Refreshgrid(): SqlCmd.CommandText = " SELECT * " SqlCmd.CommandText += " FROM HSECData" SqlCmd.CommandText += " where branchno=" &Branchno SqlCmd.CommandText += " And yearno=" &YearNo SqlCmd.CommandText += " And monthno=" &monthNoThis is working fine, initially the datagrid is empty and then displays data when I select say, branch- Melbourne, Year-2005, Month-October and other exisiting combinations.The problem I am stuck at is when the page loads, initially I want all the data to be displayed in datagrid, i.e. for 'All' branches, 'All' years and 'All' months and then when I select combinations of these dropwdown lists as above the data should be filtered and displayed in those selected combinations. but as of now I get and empty datagrid when I select 'All' from these 3 drop down lists or when the page opens the first time.Can someone kindly guide me with the correct SQL cinstruct to achieve both the requirements?Thanks,Aartee.P.S. I am sorry if I have posted this question in a wrong category in the forum, I was unsure whether I should post it in Datagrid category or SQL server category, I thought this was my best bet.My aplogies.

I need to transmit data from a ##table to an .xls file. The data is exported only for the first time. However, after a while the table will be dropped by SQL Server 2005 automatically.
I'm using Execute SQL Task to check for the existence of an ##Table. And, if does not exists the ##table should be created or something like the example below.
Ex:
IF NOT EXISTS (
SELECT *
FROM ##StateProvince
)
SELECT * INTO ##StateProvince
FROM Person.StateProvince
GO
To keep the session of the ## Table active, but the following error is thrown :
The NOT SQL construct or statement is not supported.

Let say I have 6 tables. I want to autogenerate the PK for each table and that is unique for each table and cant be duplicated on other tables. Let say I have table with PK of 1, so table2 to table6 wouldnt have a PK of 1. If table2 have a PK of 2, table1, table3 to table6 wouldnt have a PK of 2. Same for others. Identity will not be appropriate. Will 'uniqueidentifier' data type suffice? How bout guid? Or what must be my datatype? Or what will I do to implement this? Any links? Thanks

Hi, All
I'm using Gridview and SqlDataSource to dynamically display the contents in different tables, as followed:
<% dataSource.ConnectionString = System.Configuration.ConfigurationSettings.AppSettings["connectionString"]; dataSource.SelectCommand = "SELECT * FROM " + tableName; gridView.DataBind();
dataSource.UpdateCommand = "";%>
<asp:SqlDataSource ID="dataSource" runat="server"></asp:SqlDataSource><asp:GridView ID="gridView" runat="server" DataSourceID="dataSource" AllowPaging="True" AllowSorting="True" AutoGenerateEditButton="True" BorderColor="Silver" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" PageSize="20" DataKeyNames="ID" OnRowDataBound="tableGridView_RowDataBound"> <HeaderStyle BackColor="#C0C0FF" /> <AlternatingRowStyle BackColor="#C0FFC0" /></asp:GridView>
The datasource take the "tableName" as argument to determine which table to display. My problem is I can't figure out a way to programmatically construct the UpdataCommand for the SqlDataSource. I try to get the field names from the HeaderRow, but all the cells are empty in this row.
Does anyone know what causes the problem or how to construct the UpdateCommand properly. Thanks!

Hi,In the past I build up the query string within VB.NET page and easy to add the filtering statements in the SQL statement since it is just a string. For example, if user selected an option then include it in the filter, otherwise, just return all rows from table:Codes in ASPX.VB: Dim SQL as String="SELECT * From Table1" IF UserOption <> Null then SQL = SQL & " WHERE Column1=" UserOption" End ifNow, since I have a complicated page which need to use Stored Procedure to manapulate a temporary table before the final result. But I found when I want to add some user options similar to above, I found I don't know how to do it in Stored Procedure. In the Stored Procedure Property screen, I can't insert a IF..THEN statement within a SELECT statement. Seems I can only check the user option first and then determine the SELECT statement to use. That is: IF UserOption THEN SELECT statement 1 ELSE SELECT statement 2.But it is impossible for me to do this way since I'm not only one user option on the page. User usually can have several filters/selections on his screen. So if check which user option(s) are selected and write a static SELECT statement for it, I will have to program a complicated store procedure to cater all combinations for all user options (where some options may be null).Hope you can understanding what my mean and give me advices.Regards,Raymond

Referencing the sample stored procedure
below that updates table 'this_table' containing
3 INT columns: 'key', 'col2', 'col3'.
How do I revise the stored procedure so that *** I do not
have to specify ALL the columns *** to update just one column?
e.g. if I want to update @col3 to 9 (exec sp_update_table, @col3 = 9),
how can I set col2 to its existing value?
create proc sp_update_table
@key int,
@col2 int,
@col3 int
as
update this_table
set col2 = @col2,
col3 = @col3

I am trying to use a Pivot T-SQL statement in the Table Adapter Configuration Wizard in Visual Studio 2005. I get the error message "The Pivot SQL construct or statement is not supported". Then it executes the SQL statement as if there were no error. Unfortunately, it will not create the table adapter because of the error. Below is the T-SQL statement I am using.
SELECT OrderNumber, OrderDate, custlastname, [1001] AS Dept01, [1002] AS Dept02, [1003] AS Dept03, [1004] AS Dept04, [1005] AS Dept05, [1006] AS Dept06, [1007] AS Dept07, [1008] AS Dept08, [1009] AS Dept09, [1010] AS Dept10, [1011] AS Dept11, [1012] AS Dept12
FROM
(SELECT Orders.Ordernumber, Orders.OrderDate, Customer.custlastname, DeptID, OrderDetail.DetailAmount
FROM OrderDetails od JOIN
Orders ON Orders.OrderNumber = od.OrderNumber JOIN
Customer ON Orders.CustomerID = Customer.CustID
WHERE (DATEPART([Year], OrderDate) = '2006')) p
PIVOT (SUM(OrderDetailAmount) FOR DeptID IN ([1001], [1002], [1003], [1004], [1005], [1006],
[1007], [1008], [1009], [1010], [1011], [1012])) AS pvt
ORDER BY OrderNumber
The statement works fine in Management Studio so I know the syntax is correct.
Any Ideas?
Thanks,
James

Hello,
I am currently trying to import following Excel Datasheet into my SQL 2005 Database with SSIS:
Column: Created
For example cells: 18.03.2008 17:47:43
So now I want to get the time, the year, the month and the day seperately out of this column for a later OLAP Analysis.
I created a Data Flow Task, where I imported the Excel source and set the SQL database as target. But now I don't know really how to work with the "Data Conversion" where to extract the dates. In Excel this is just a "customized" cell.
Anyone who can help me in this situation?
Thank you very much.
Greets from Germany,

Hi All!
Could You comment the next situation:I'm configuring my TableAdapter just like Scott Mitchell does in his tutorialhttp://www.asp.net/learn/data-access/tutorial-70-vb.aspxThe only principal difference is that I need Insert/update and deletemethods to be generated (His aim is only SELECT).I'm also using analytic function (ROW_NUMBER) and I'm also gettinwarning “The OVER SQL construct or statement is not supported.� Yousay then that it could be ignored. But, in this case statements tomodify data (insert/update and delete) aren't being generated, thoughafter warning SQL command is executed without errors.
So, the question is obvious - why does this warning occur and how mustI perform configuration of TableAdapter based on SQL query withanalytic function?
