Sqlserver. SQL Injection. You should review all code that calls EXECUTE, EXEC, or sp_executesql. You can use queries similar to the following to help you identify procedures that contain these statements. This query checks for 1, 2, 3, or 4 spaces after the words EXECUTE or EXEC. SELECT object_Name(id) FROM syscomments WHERE UPPER(text) LIKE '%EXECUTE (%' OR UPPER(text) LIKE '%EXECUTE (%' OR UPPER(text) LIKE '%EXEC (%' OR UPPER(text) LIKE '%SP_EXECUTESQL%' Wrapping Parameters with QUOTENAME() and REPLACE() In each selected stored procedure, verify that all variables that are used in dynamic Transact-SQL are handled correctly.
When you use this technique, a SET statement can be revised as follows: --Before: SET @temp = N'select * from authors where au_lname=''' + @au_lname + N'''' --After: + REPLACE(@au_lname,'''','''''') + N'''' Injection Enabled by Data Truncation Any dynamic Transact-SQL that is assigned to a variable will be truncated if it is larger than the buffer allocated for that variable. @loginname sysname,

Published: Wednesday, July 30, 2003 By Dave Long Introduction Oftentimes, when building Web-based reporting tools we need to show totals and sub-totals for information stored in the database. For example, imagine that you worked at an eCommerce site like Amazon.com that sold products from a variety of categories: books, electronics, clothes, etc. Managers would likely be very interested in seeing a summary of sales for a given time period, showing sales from each item in each category, as well as a summary listing the total number of sales for each category and for all products. A common way of providing such summarized data is the running total method.
In this article, however, we will examine one alternative to the running total method: the WITH ROLLUP method. Understanding WITH ROLLUP The WITH ROLLUP syntax, as we'll see shortly, can only be used when a SQL query contains a GROUP BY clause. This would return results like: The SQL Books Online describes the ROLLUP operator as follows: State of the Nation. CodeByDesign. Visual_SQL_JOINS_orig.jpg (JPEG Image, 966x760 pixels)
SQL pie chart. My other half says I'm losing it. But I think that as an enthusiast kernel developer she doesn't have the right to criticize people. ("I like user space better! " - she exclaims upon reading this). Shown below is a (single query) SQL-generated pie chart. I will walk through the steps towards making this happen, and conclude with what, I hope you'll agree, are real-world, useful usage samples. Requirements We need a generic query, which returns at least these two columns: name_column and value_column. SELECT name AS name_column, value AS value_column FROM sample_values2; +-------------+--------------+ | name_column | value_column | +-------------+--------------+ | red | 1 | | blue | 2 | | orange | 3 | | white | 4 | +-------------+--------------+ Find sample data in pie_data.sql.
Part 1: expanding the original query We're going to need to take the above query's results and expand them: how much is the ratio from total, per value? Part 2: behind the scenes of the pie chart Showcase OK. Conclusion. Welcome to SQL Server Central. 10 Things You Shouldn't Do with SQL Server (Data Access Developer "Don'ts") Microsoft SQL Server - Using COALESCE to Build Comma-Delimited String. By Garth Wells on 1 February 2001 | 27 Comments | Tags: Application Design Garth is back with another article. This one talks about building a comma-separated value string for use in HTML SELECT tags. It's also handy anytime you need to turn multiple records into a CSV field. It's a little longer and has some HTML but a good read. I was reading the newsgroups a couple of days ago and came across a solution posted by Itzik Ben-Gan I thought was really smart.
For those of you with limited experience working with HTML, I need to explain that the values selected in a multi-select list box are concatenated in a comma-delimited string. <SELECT name="RetailCategory" multiple><OPTION value=1>Shoes <OPTION value=2>Sporting Goods <OPTION value=3>Restaurant <OPTION value=4>Women's Clothes <OPTION value=5>Toys </SELECT> If a user selects more than one option the value associated with RetailCategory is a comma-delimited string. I say final, because the actual HTML is built on-the-fly using VBScript.
