Dynamically Select Column

Sep 29, 2004

Hey all. I'm trying to create a stored proc that will update a variable column, depending on the parameter I pass it. Here's the stored proc:








CREATE PROCEDURE VoteStoredProc


(


@PlayerID int,


@VoteID int,


@BootNumber nvarchar(50)


)


AS





DECLARE @SQLStatement varchar(255)


SET @SQLStatement = 'UPDATE myTable SET '+ @BootNumber+'='+ @VoteID + ' WHERE (PlayerID = '+ @PlayerID +')'





EXEC(@SQLStatement)





GO








I get the following error:





Syntax error converting the nvarchar value 'UPDATE myTable SET Boot3=' to a column of data type int








The update statement is good, because if I use the stored proc below (hard-coded the column), it works fine.





CREATE PROCEDURE VoteStoredProc


(


@PlayerID int,


@VoteID int,


@BootNumber nvarchar(50)


)


AS





UPDATE


myTable


SET


Boot3 = @VoteID


WHERE


PlayerID = @PlayerID


GO








Is there a way to dynamically choose a column/field to select from? Or is my syntax incorrect..?


Thanks!

Is it possible that I can use variable for column name?, if yes how? or is there any other way to achieve this task ?

How Can I Dynamically Build Sql SELECT Using ASP 1.0 Array Concept

Jun 6, 2007

The below code is ASP 1.0 to dynamically search a database and I want to use the same concept for a ASP.Net 2.0 solution.  Do I do this in the code behind or on the aspx page and if on the aspx page what controls do I use for the array split?  Basically where do I start.  It took me a long time to get this old code working, I am hoping it is simpler in 2.0.
Thank you
OLD ASP 1.0 code to dynamically build a Sql Select statement for searching a database using one or more search words entered by user.
If Request.Querystring("kwdSearch") <> "" ThenDim kwdString, ArrKwdString, iCountiCount = 0 kwdString = Replace(Request.Querystring("kwdSearch"), "'", "''")ArrKwdString = Trim(kwdString)ArrKwdString = Split(kwdString, " ",-1,1) For iCount = 0 to UBound(ArrKwdString) If iCount < UBound(ArrKwdString) Then  Criteria = Criteria & "tblLinkInfo.L_Keywords LIKE '%" & ArrKwdString(iCount) & "%' AND "  Else  Criteria = Criteria & "tblLinkInfo.L_Keywords LIKE '%" & ArrKwdString(iCount) & "%' " End ifNext    RS.Open "SELECT * FROM tblLinkInfo Where (" & Criteria & ") AND L_Enabled = 1 ORDER BY " & SortBy & "L_Rank", CNN, 3 If RS.EOF Then  If Rs.State Then RS.Close  RS.Open "SELECT * FROM tblLinkInfo WHERE L_Description LIKE '%" & Replace(Request.Querystring("kwdSearch"),"''","'") & "%' AND  L_Enabled = 1  ORDER BY " & SortBy & "L_Rank", CNN, 3  End If

SELECT - Dynamically Determine Fields To Return

Dec 6, 2004

Hello,

I m writing a stored procedure to query a table Population that has the following fields - CityId, CityName, Plus0, Plus10, Plus20, Plus30, Plus40, Plus50, Plus60, Plus70, Plus80. The field Plus0 contains the number of people of age > 0 living in the city, Plus10 contains the number of people of age > 10 living in the city and so on. Given the city id and age groups like 20To40, 50To60, 40Plus, etc., I should be able to query the number of people in the city corresponding to the requested age group. Note that if the requested age group was 20To60, I need to make use of only 2 fields Plus20 and Plus60 in the table to compute this value. And if the requested age group was 40Plus, then I need only the value in the field Plus40. The problem is that a wide variety of age groups can be requested like 0Plus, 10Plus, ... , 80Plus, 0To10, 0To20, 0To30, .... 70To80.

Which is the most effecient way to handle this ?

1. Have a stored procedure that returns all the fields even though only 1 or 2 of them would be actually used ?

In this case, if I returned data for a large number of cities then there would be a lot of unnecessary information that was returned by the query. Lots of data would be passed through the network though most of it would not be used.

2. Have a stored procedure that takes in parameters @Plus0, @Plus10, @Plus20, .. @Plus80 that are bits indicating whether the field was required or not and then using a CASE statement to return values for a field only if the corresponding bit parameter was set, and returning NULL if the corresponding bit paramter was not set ?

In this case, I would be returning NULL for all those fields that were not required for a particular age group. This would save some network bandwidth, wouldn't it ?

3. Pass in the age group itself (ex: 0To20) as a parameter to the stored procedure and have lots of IF statements, one for each age group, that return only the fields that are needed for that age group.

This leads to a lot of code repitition.

4. Use a similar approach as above but use dynamic SQL queries to avoid code repitition.

But using dynamic SQL queries can affect the performance of the stored procedure as they need to be compiled each time.

5. Any other possible approaches ??

Looking forward to your responses,

Thanks much,

bmgun.

Does Reporting Services Allow You To Select A Dataset Dynamically?

Apr 30, 2007

I have a remote report ...
I need to call one of two stored procedures depending on which parameters were passed to the report. (Both stored procedures return the same fields.)
Does SQL Reporting Services allow you to switch the dataset or stored procedure name dynamically? If so, where do I put the logic? Right now I have it working with one stored procedure.
I'm thinking that I should just make one stored procedure that takes all parameters and calls one of the other two stored procedures. Do I have any options besides this?

Thanks in advance!

Dynamically Access A Column In A Table

May 21, 1999

I'm trying to create a procedure that can access a column in a table dynamically.<br>
Lets say I have the following table<br>
create table table_items<br>
(rec int identity not null,<br>
item1 int,<br>
item2 int,<br>
item3 int)<br>

and I have a procedure as such

create procedure access_item<br>
@rec int,<br>
@itemindex int,<br>
@item int as<br>
select @item = (select item1 from table_items where rec = @rec)<br>

However, the column I want to access is @itemindex.<br>
If @itemindex = 1, then set @item to item1<br>
if @itemindex = 2, then set @item to item2<br>
if @itemindex = 3, then set @item to item3<br>

I can't use a simple 'if/then' selection, because the number of columns in the table can grow, and I don't want to have to rewrite the procedure everytime a column is added.<br>
How do I do this?<br>

I tried to use an execute command, as such<br>

create procedure access_item_2<br>
@rec int,<br>
@itemindex int,<br>
@item int as<br>
declare @sql varchar(255)<br>
select @sql = "select @item = (select item" + convert(varchar(2), itemindex) + " from table_items where rec = @rec)"<br>
execute (@sql)<br>

but when the procedure runs, I get the following error:<br>
'@item is not a valid variable.'<br>

What else can I do?<br>

Please e-mail me at sam@microcsl

Dynamically Changing Column Headings

Feb 5, 2008

We have a query in which we have data in fields called TS1Min, TS1Max, TS1Avg, TS2Min, TS2Max, TS2Avg etc.

We have a different table in which we define that vale of TS1, TS2, as an example TS1 might equal RED, TS2 might equal BLUE.

We have written a query that puts TS1Min, TS1Max, TS1Avg, TS2Min, TS2Max, TS2Avg in a temp table #TEMPA

and we also put the values of RED and BLUE in another temp table #TEMPB

now we want to select * from #TEMPA but rename the headings TS1Min to display RED-TS1Min, TS1Max as RED-TS1Max, TS1Avg as RED-TS1Avg etc...

any ideas on how to do this

Writing Query To Dynamically Select A Database Table

Is there a way I can write a query to dynamically select a database table. That is, instead of having a variable for a certain column like customerId which would be €ścustomerID = @customerID€? I want to use the variable to select the table. I assume I may have to use a stored procedure but I am unclear as to how this would be coded.

Thanks

Want A Stored Procedure To Dynamically Select Views Pulled From A Table.

Feb 1, 2007

I am building a dashboard features that allows user to select reports from a dropdownlist. It is pulling from a table called Reports (cols: ReportID, Description, sqlView) In this Report table the report is associated to a view that queries the report.
And the user's selections are stored in table called UserReport (cols: userID, ReportID, createDt) .
I need to get a Dataset to contain datables of all reports selected. (for example a user select 3 reports, the dataset should contain 3 datables that represent the report).
I want to accomplish this by create a store procedure that queries the Reports table and then dynamically executes the views that related to the user selected reports. Can anyone give me an example on how to create the storeprocedure? 
Thanks,
CG
