DataSource Controls :: Insert Any Kind Of Text Into A Sql2005 Database
Mar 4, 2010
I want to be able to insert any kind of text into a sql 2005 database. The column im using to store this is ofVARCHAR(MAX) type . Basically , even if the text contains special charectars or unicode content or html tags I should still be able to insert it into the database without any errors. Please guide me on how to achieve this.Things I tried that did not work !- changed the column to type NVARCHAR(MAX)-Tried Server.HTMLencode for the column that accepts the textIs regex a solution for this problem. If so how can i implement it?
how I add multi-column constraint to a table in SQL2005 ?
I want to prevent a user from entering a row in the table where Column_A = 1, Column_B = 2 etc where there is already a row where Column_A = 1, Column_B = 2.

Now i want to insert these dates
It's probably something small but I can't seem to find what went wrong. I am trying to insert information into my database. It goes through the code just find but it doesn't insert into my database. Here's my code:
I m uploading a text file. I want to read that text file line by line and I want to save that data into database if there are no errors in that text file. I have 5 different columns in database and I want to take those 5 columns data in the text file and insert into respective columns.
For this, which is the best way to do. Can we read and insert data into respective fields in no time.

I have Gridview on my webapplication and it is getting filled with multiple rows . When clicked on Save I want to Insert all rows without calling multiple database hits.
Is there any way I can insert all rows by single db hit?
I want to insert almost 400 rows in one database call in asp.net. I am using .net 3.5 and sql server 2005. What should be the best possible way for doing that?.
I am generating a unique Ref number using this sql statement: SELECT REPLACE(STR(CAST(CAST(NEWID() AS binary(5)) AS bigint),12),0,0) as REF Subsequently, I need to insert this REF into sql database table in stored procedure. Here is what I did in my stored procedure:
USE [iBankRecords] GO /****** Object: StoredProcedure [dbo].[stp_addPayee] Script Date: 07/05/2010 21:57:07 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROC [dbo].[stp_addPayee] ( @CUSTID char(10), @PAYEEACCNUM nvarchar(20), @PAYEEACCTYPE char(10) , @PAYEENAME char(20), @PAYERINITIAL char(20), ) AS DECLARE @ReturnValue int INSERT INTO PAYEE (CUSTID, PAYEEACCNUM,PAYEEACCTYPE,PAYEENAME,PAYERINITIAL, REF) VALUES (@CUSTID,@PAYEEACCNUM,@PAYEEACCTYPE,@PAYEENAME,@PAYERINITIAL, REF) IF @@ERROR<>0 BEGIN PRINT 'ERROR' SET @ReturnValue=1 RETURN @RETURNVALUE END ELSE BEGIN SET @ReturnValue=0 RETURN @RETURNVALUE END
May I know how do I have generating a unique ref num and inserting the REF into the above statement?
I have to in sert the gridview values into database, the values can be single or more than one values, so here i have to use the XML to store the data, but my question is?
i have to sent the values as a string, to the database, so how i convert that, and how could i retrieve the values as it is, and stored or display to the another gridview.
I want to insert a particular value against a range of dates into my sql server database from the front end using c#.
the table has the column date and worker. so i desire that the user writes the name of the worker and then enters a From and To range into two textboxes so that thorugh a loop function the name of the worker gets written into the table along with the range of chosen dates.
I have been in the process of updating my code with security methods, and I've been learning this from [URL] (or "Security Guidelines: ASP.NET 2.0"). In the middle of the page under "When Constructing SQL Queries, Use Type Safe SQL Parameters" it says "Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input". Now, what they suggested was to use code like:
"DataSet userDataset = new DataSet(); SqlDataAdapter myCommand = new SqlDataAdapter(LoginStoredProcedure", connection); myCommand.SelectCommand.CommandType = CommandType.StoredProcedure; myCommand.SelectCommand.Parameters.Add("@au_id", SqlDbType.VarChar, 11);........"
So, that would be how I would modify my current code base to use type safe parameters in sql updating/inserting.
Getting to my actual question, as it was said "Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input". First off, this suggests that this should apply to unfiltered input. Also, in their example they only did this for an ID.
So, what I'd like to know, when it comes to "unfiltered input", does this mean as long as the input is unfiltered I must use type safe parameters, or even filtered input shall have this (just to be sure), like, input that has been ran through a regularexpression check? Shall I do this for all values I insert/update into the database, or just IDs and important things?
The way I see it right now is that it would be a good precaution to just do type safe checks on everything (literally) that updates/inserts into the database just to be extra safe. But, I really am unsure if this is really the best idea, because if I did, would this possibly cause overprocessing of information? Can this cause too much strain on server resources? If my fears serve true, what would be a good suggestion of how I could implement this properly without having to worry about what I said?
