article from Naomi N: SET ANSI_PADDING Setting and Its Importance Problem Description Recently I got an interesting escalation to solve for the client. Our VFP based application was change ansi_padding on table getting the following SQL Server error: "Violation of PRIMARY KEY constraint ‘rep_crit_operator_report'. Cannot insert duplicate key in object ‘dbo.rep_crit' The duplicate key value is (ADMIN, REPORT_PERIOD_SALES)." Resolution To be honest, I should have guessed what was happening by myself. But I must admit that I still didn't, I sent e-mail to my colleagues asking what do they think about that strange what is ansi_padding behavior and I also posted this thread Weird problem with the client . My colleague immediately recognized the problem as one he already experienced with another client. And Latheesh NK also pointed out into SET ANSI_PADDING setting as possible culprit. So, somehow several tables were saved with the wrong ANSI_PADDING setting being in effect and therefore the column's setting overrode sessions settings. Recently I made a change in our VFP applications to save varchar columns as varchar (prior to that all varchar columns were automatically padded with spaces to their length). This caused the above mentioned problem when the client upgraded the software to the recent release version. The solution to that particular error was to run ALTER TABLE statement to alter report column to be the same width as the original column but using SET ANSI_PADDING ON before running the statement. This fixed the wrong padding on the column. This is how we can check column's status in design mode when we right click on the column and check its properties: ANSI Padding Status is close to the

Server Management Studio’s Ugly ANSI_PADDING Bug Aug 5, 2014 by Michael K. Campbell in Practical SQL Server RSS EMAIL Tweet Comments 0 It’s always a bit hard to define what exactly constitutes a https://blogs.msdn.microsoft.com/user_ed/2013/08/08/sql-server-2012-set-ansi_padding-setting-and-its-importance/ bug. In this case, I’ll argue that if/when Microsoft says that you shouldn’t USE a particular feature—and then its tooling USES that feature (by default—and in the exact wrong configuration that they warn against), then that behavior constitutes a bug. Related: Protect Yourself in SQL Server Management Studio with Color Coding Instances To that end, just note for the purposes of this post, that turning ANSI_PADDING OFF http://sqlmag.com/blog/sql-server-management-studio-s-ugly-ansipadding-bug is bad or something you really want to avoid. Microsoft’s own documentation for SQL Server (as of 2005), has also warned SQL Server users and developers to stay away from trying to set ANSI_PADDING OFF—as per this warning in Books Online: In a future version of SQL Server ANSI_PADDING will always be ON and any applications that explicitly set the option to OFF will produce an error. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Where this becomes a bug, however, is that SQL Server Management Studio (SSMS) will—by default—script "SET ANSI_PADDING OFF;" statements out into the scripted definitions of your objects when you generate scripts. It's a known issue—but one that Microsoft doesn’t seem to think is a big deal. Recently, this bug was responsible for one of my clients losing over 8 years' worth of financial data. (Side Note: Nice to note that all of that testing and verification of the Disaster Recovery Plan worked out in the end—as we were able to fully recover.) The Problem with SSMS' Generation of Scripts with ANSI_PADDING OFF SSMS will script SET ANSI_PADDING OFF statements out whenever you

I have never used this option but it looks ansi_padding sql server like it can actually save a lot of database spaces for char and varbinary fields if used correctly.

If one database object is created, used, referenced, or whatever with it ON, a second one is done so with it OFF, and you try to work with both at the same time (two tables, procedure referencing table, etc.), your results may be inconsistant or may not make sense, and it will take you Forever to figure out what's going on. (There are other SET settings like this, and worse. I hope they deprecate them all.) share|improve this answer answered Sep 12 '09 at 18:57 Philip Kelley 27.4k63665 Well your opinion makes sense for me as an answer ;) T
Studio) 2005/2008, you know the quickest way to do this is to right click on the table and "Script Table As" à "Create To" à "New Query Editor Window". When this is done, you would expect a clean create table script, with defaults, primary and foreign keys, but instead I received the following: SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOSET ANSI_PADDING ONGO CREATE TABLE [dbo].[Table1]( [col1] [int] NULL, [col2] [varchar](20) NULL, [col3] [money] NULL, [col4] [timestamp] NOT NULL, [col5] [uniqueidentifier] NULL, [col6] [xml] NULL) ON [PRIMARY]SET ANSI_PADDING OFFALTER TABLE [dbo].[Table1] ADD [col7] [varchar](30) NULLALTER TABLE [dbo].[Table1] ADD [col8] [char](25) NULLALTER TABLE [dbo].[Table1] ADD [col9] [nchar](40) NULLALTER TABLE [dbo].[Table1] ADD [col10] [nvarchar](10) NULLSET ANSI_PADDING ONALTER TABLE [dbo].[Table1] ADD [col11] [varchar](30) NULLALTER TABLE [dbo].[Table1] ADD [col12] [char](25) NULLALTER TABLE [dbo].[Table1] ADD [col13] [nchar](40) NULLALTER TABLE [dbo].[Table1] ADD [col14] [nvarchar](10) NULLGOSET ANSI_PADDING OFFGO Why aren't all the columns created in the initial "Create Table" statement? The answer lies in how the columns were initially added to the originating table. When using SSMS to create objects, certain ANSI settings are set on the connection to the server. To view these ANSI settings, navigate to "Tools" à "Options" à "Query Execution" à "SQL Server" à "ANSI" So, by default, "Set ANSI_PADDING" is set to ON for all connections to the server opened via SSMS. One problem is that not all tools are nice enough to set these options for you automatically. If, for example, I used SSMS to create this table initially: Create Table Table1(col1 int,col2 varchar(20),col3 money,col4 timestamp,col5 uniqueidentifier,col6 xml) Then as we add more columns to Table1, another tool is used to add the columns col7, col8, col9 and col10. This tool though doesn't set the ANSI_PADDING to ON by default. Alter Table Table1Add col7 varchar(30) ,col8 char(25) ,col9 nchar(40) ,col1
