Dynamic ColumnName
Jun 3, 2005Howdy all,I'm trying to create a sproc that has the column name and search text as input parameters with dynamic SQL... what I have is:-- Create a variable @SQLStatementDECLARE @SQLStatement varchar(255)SELECT @SQLStatement = 'SELECT * FROM myTable WHERE (''' + @ColumnName + ''' = ''' + @SearchText + ''')'-- Execute the SQL statementEXEC(@SQLStatement)The procedure works (at least in Query Analyzer, once I declare/set @columnname and @searchtext) in that I don't get any errors. But it returns a blank table with "0 rows affected". However, if I hardcode the variables, it returns the proper data. What's wrong with my select statement?? Thanks!!JP

Apr 30, 2004Hi,
What is the difference between
<Tablename> . . <ColumnName> and <Tablename> . <ColumnName>
this syntax we are using in Storedprocedures.
In SQL 2000, <Tablename> . . <ColumnName> is not working
Eg:
Tablename =a
Column Name = b
Difference between a..b and a.b
Can anyone let me know.
TIA,
Ravi

Dec 3, 2006I want to dynamically determine which column I select data from. The table I want to select from looks like this:tblSexualitySexualityID int PKEN nvarchar(20)NL nvarchar(20)DE nvarchar(20)Based on the value of variable @LanguageColumnName I want to select the value from either column "EN", "NL" or "DE"In the sample below the value of @LanguageColumnName is "NL".Unfortunately the value of sexualityname is ALWAYS: "tblSexuality.NL" and not the value from that specific column...how can I alter my procedure so that it does the select the value from that column?ALTER PROCEDURE [dbo].[spFindUsers]@LanguageColumnName nvarchar(3),@startRowIndex int,@maximumRows intASBEGINSET NOCOUNT ON;
declare @tblSexualityName nvarchar(40)set @tblSexualityName='tblSexuality.' + @LanguageColumnName SELECT UserName,UserCode,ThumbNailPicture,BirthDate,ShowAgeOnly,IsMale,NearestBigCity,DistanceToNearestBigCity,Description,IsDonator,IsVIP,SexualityName FROM(SELECT ROW_NUMBER() OVER (ORDER BY UserCode) as RowNum,tblUserData.UserName,UserCode,IsDonator,IsVIP,Description,BirthDate,IsMale,ShowAgeOnly,tblCountries.CountryPicture,@tblSexualityName as sexualityname,tblCountries.CountryName,ThumbNailPicture,LastActivityDate,UserRanking,NearestBigCity,DistanceToNearestBigCity FROM aspnet_Users INNER JOIN tblUserData ON aspnet_Users.UserId = tblUserData.UserID INNER JOIN tblCountries ON tblUserData.Country=tblCountries.CountryID INNER JOIN tblSexuality ON tblUserData.Sexuality=tblSexuality.SexualityID) as MemberInfoWHERE RowNum > @startRowIndex AND RowNum <= (@startRowIndex + @maximumRows)END
SELECT Columns By Column-index NOT By Columnname!
Nov 20, 2005Hello all,
how can I select one or more columns from a table by column-index and NOT by columnname?
e.g.:
SELECT tbl1.[1], tbl1.[2], tbl1.[3] FROM Orders AS tbl1
and NOT like this:
SELECT tbl1.OrderNo, tbl1.ProductNo, tbl1.Price FROM Orders AS tbl1
Is that possible in MS-SQL 2000?
Thanks a lot in advance
kind regards

SSIS - Failure Inserting Into The Read-only Column ColumnName
May 10, 2007Hi folks, I have a little challenge for you, I hope :)
The short story is as follows: I have multiple rather well normalized tables, and a view which connect them all togheter. In one of the tables I have an xml column, which I in the view to varchar(4000), since SSIS doesn't like xml all that much. To make the view updateable I have an instead of trigger placed on it, which works quite perfectly from T-SQL. SSIS however, claims that I cannot insert to a read-only column. Does anyone have the slightest idea how I can get around this?
The only solution I can think of is having two columns for the XML data, one as varchar and the other as varchar, then having a trigger updating the xml column when the varchar is updated, but that would require recursive triggers, which I am not too happy with.
Cheers
How To Save Filename As Columnname In Flat File Dest Config
Oct 20, 2006I have created a SSIS pkg (datasource and flat file destination)
I need to have the flatfile renamed after each exec to a column name that exists in the table I am running the pkg against.
Where does the code get put to make this change after the file has been created?
Basically if I could run T-SQL after the file creation, I could make it work.
thx..
