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>
Hi, There is a table exists in a database, I have to write a stored procedure to create the same table in different database, with the same column name and field. This should be done in runtime. Is it possible. The table will be passed as a parameter to the stored procedure.
I have the folowing databases DB1,DB2,DB3,D4,DB5........ I have to loop through each of the databases and find out if the database has a tablename with the word 'Documents'( like 'tbdocuments' or 'tbemployeedocuments' and so on......) If the tablename having the word 'Documents' is found in that database i have to add a column named 'IsValid varchar(100)' against that table in that database and there can be more than 1 'Documents' table in a database. can someone show me the script to do it? Thanks.
I got a table which gets populated by stor proc where we pivot the Sum(Balance of mortgage) by YYYYMM for the whole duration of the loan term.

Hi I’m trying to alter a table and delete a column I get the following error. The object 'DF__Morningst__LastU__19EB91BA' is dependent on column 'LastUpdated'. ALTER TABLE DROP COLUMN LastUpdated failed because one or more objects access this column. I tried deleting the concerned constraint. But the next time I get the same error with a different constraint name. I want to find out if I can dynamically check the constraint name and delete it and then drop the column. Can anyone help.IF EXISTS(SELECT 1FROM sysobjects,syscolumnsWHERE sysobjects.id = syscolumns.idAND sysobjects.name = TablenameAND syscolumns.name = column name)BEGIN EXECUTE ('ALTER TABLE tablename DROP CONSTRAINT DF__SecurityM__DsegL__08C105B8')EXECUTE ('ALTER TABLE tablenameDrop column columnname)ENDGO

I am looking a way to export SQL Server 2005 DB tables to Access file dynamically. Like if i have added or removed any tables from SQL DB then when i run SSIS package it should export that table with data to Access file. is there any easy way to do this. if it is not them please someone please tell me which controls should i look at and which technique i should use to do this.
my scenario is that, i have a table in which i have column such as col01,col02,col03....col31
i want to retrieve the records related to that column by specifying the name dynamically (by using loop) as fist three character are same ('col??') and i have to do integer increment in last two character (???01...???31). Is it possible that I can use variable for column name?, if yes how? or is there any other way to achieve this task ?

Hi,In my stored procedure I'm doing a SELECT onINFORMATION_SCHEMA.TABLE_CONSTRAINTS. However there is no unique id onthis table, so I was wondering if it was possible to add it dynamicallyin my SELECT, so that I would assign a unique id to each recordreturned by my SELECT?Thanks for your support.
I’ve got a situation where the columns in a table we’re grabbing from a source database keep changing as we need more information from that database. As new columns are added to the source table, I would like to dynamically look for those new columns and add them to our local database’s schema if new ones exist. We’re dropping and creating our target db table each time right now based on a pre-defined known schema, but what we really want is to drop and recreate it based on a dynamic schema, and then import all of the records from the source table to ours.It looks like a starting point might be EXEC sp_columns_rowset 'tablename' and then creating some kind of dynamic SQL statement based on that. However, I'm hoping someone might have a resource that already handles this that they might be able to steer me towards.Sincerely, Bryan Ax
we have a table in our ERP database and we copy data from this table into another "stage"Â table on a nightly basis. is there a way to dynamically alter the schema of the stage table when the source table's structure is changed? in other words, if a new column is added to the source table, i would like to add the column to the stage table during the nightly refresh.
I have a function that returns a table from a comma-delimited string.
I want to take this a step further and create a function that will return a set of tablenames in a table based on a 'group' parameter which is a simple integer...1->9, etc.Obviously, what I am doing is not working out.
CREATE FUNCTION dbo.fnReturnTablesForGroup ( @whichgroup int ) RETURNS @RETTAB TABLE ( TABLENAME VARCHAR(50)

hi, I have a question regarding calling sql table columns dynamically? workflow would go as:1. user enters search term into a textbox2. user checks a checkbox to search by column in sqldb (eg.. firstname or surname) pseudo sql would go like......SELECT +%column1(checkbox1.value)%+ OR +%column2(checkbox2.value)%+ OR +%column3(checkbox3.value)%+WHERE column1 = +%TextBox.Text%+ OR column2 = +%TextBox.Text%+ 3. display results in gridview my sql needs to improve greatly so any code insight(good book or link) would be terrific . thanks

I have to display three months name as column name in ssrs reports. These month column will be dynamically. So i have to display the column dynamically.
Is it possible to creates fields of the table dynamically?. I have this situation in my project. This is just a small sample. I have row of length 140. I don't wan't to declare all this fields manually using the create table command.
The description of table is as, in this table all the field are of type varchar only, there are like 140 columns.
Table: Dummy ================================================== == field1 field2 field3.......... Empid Empname empaage1 sam 23........... 2 rai 22............ . . . n raj 45............. ================================================== == Now I want to create another table as "EMP" , with proper data type fields too..
Table: EMP ================================================== == Empid Empname empaage............ 1 sam 23............... 2 rai 22................ . . . n raj 45................. ================================================== ==
I want to do this dynamically..... Some how I need to extract those field from table[dummy]; the first row acts as a column header for the table[Emp] and the subsequent row acts as a record for the table[Emp]
A small rough snippet of the code will be appreciated....
I developed a SSRS report, the problem is i dont have data in DEV server. So i dont know how to adjust the column lengths in ssrs report. is there any property so that the column length can be adjusted dynamically based on the data length whenever data is available in production.
I have an SSIS package that moves data from SQL Server to an legacy Access database. In SQL Server, there is a date/time column that I need to split into a separate date column and time column in the access database. Initially I just created a derrived column for the time and set the expression equal to the source date/time column from SQL Server. Unfortunately, that just makes the date column and time column the same having the full date/time.
What expression can I use during a derrived column transformation to assign just the date to a derrived column and just the time to another derrived column?
As you can see, the above table has cumulative data. 1. It calculates the number of Products submitted till a particular date- weekly 2. The date columns should increase dynamically(if the dates in base table increases) each time the query is executed For ex: the next date would be 11/28/2007 I tried something like, it gives me count of €˜b€™ level and €˜p€™ level products by week declare @date1 as datetime select @date1 = '6/30/2007' while (@date1 != (select max(SDate) from dbo.TrendTable)) begin set @date1 = @date1 + 7 select Level, count(Products) from dbo.TrendTable where SDate < @date1 group by Level end what I think is required is a pivot that dynamically adds the columns for increase in date range. /Pls suggest if any other way of achieving it. Pls help!!!
