    Greetings,

    Thank you for posting this script to help standardize a database. I think it may come in handy for updating the fields in ours. It would be nice too if the script could also parse through the user created functions and stored procedures within a database and find the non-unicode compliant characters in them too.

    I fully agree - I was going to add support for changing data types in stored procedures and UDFs too, but since the database I wrote this for used neither I couldn't justify the time at work!! However, I already have scripts for re-assembling stored procedures so I might well add that support sometime soon when work is a little less chaotic. Mind you, considering that it would involve a lot of string manipulation I'd err on the side of utilising the CLR as it is more efficient at that sort of work. It's something I might have a look at sometime soon, but in the meantime there's quite a few scripts flying about to get hold of stored procedures and functions from a database so it could be an interesting project for someone! 😀

    Thank you for the useful and very compact script. While I understand not supporting SQL 2008 features like filtered indexes and data compression, you're also missing support for include columns.

    See http://www.sqlservercentral.com/scripts/Indexing/70737/[/url] for references, though your code is much more streamlined.

    Also, in your legal disclaimer, wrods->words.

    Good spot! I had fully intended to do include columns and forgot. That's something rather useful so I probably will add support for those. This was something of a rush job after a director sprung a demo to a client on us with short notice so there may be one or two errors!

    Have a good day.

    Here's a variant for FK's and CK's that fully mirrors the Trusted/Untrusted, Enabled/Disabled states (it also generates more than one column at once, suitable for greater automation).

    If you're going to set things back "the same as they were", then disabled constraints should stay disabled until your constraint maintenance handles them.

    IF EXISTS (SELECT * FROM tempdb.dbo.sysobjects WHERE id = object_id(N'[tempdb].[dbo].[#CheckSQL]'))

    DROP TABLE [dbo].[#CheckSQL]

    SELECT

    s.[name] AS OriginalSchemaName

    ,t.[name] AS OriginalTableName

    ,co.[name] AS OrginalConstraintName

    ,'ALTER TABLE [' + s.[name] + '].[' + t.[name] + '] DROP CONSTRAINT [' + co.[name] + '] ' AS DropCheckSQL

    ,'ALTER TABLE [' + s.[name] + '].[' + t.[name] + '] WITH '

    + CASE WHEN co.[is_disabled] = 0 AND co.[is_not_trusted] = 0 THEN 'CHECK'

    ELSE 'NOCHECK'

    END

    + ' ADD CONSTRAINT [' + co.[name] + '] CHECK (' + co.[definition] + ') ' AS CreateCheckSQL

    ,CASE WHEN co.[is_disabled] = 1 THEN 'ALTER TABLE [' + s.[name] + '].[' + t.[name] + '] NOCHECK CONSTRAINT [' + co.[name] + ']'

    ELSE NULL

    END AS NocheckCheckSQL

    WHERE t.[type] = 'U' --Ensure we only look at user tables.

    ORDER BY t.[name], co.[name]

    SELECT * FROM #CheckSQL ORDER BY OriginalTableName, OrginalConstraintName

    It already does pay attention to trusted/untrusted and enabled/disabled status - and generates all columns without the need for loops/cursor or temp tables.

    It doesn't actually disable constraints that were previously disabled; run a quick test and see for yourself.

    I hate to use the old developers refrain but...it worked on my db. There were several constraints which had been disabled and they were again afterwards. I will re check this but I'm pretty certain it does this already.

    Hmmm...clearly some brain melt going on from my end. Serves me right for checking this on my phone whilst out drinking! I'm going to amend the script to grab include columns (I though about doing them before, as I recall, but since the DB I was working on had none I didn't bother to save time, but it'll annoy me if I don't!) and yes, the constraints aren't coming up disabled/untrusted. Again, omission on my part. Oh well, never said it was complete or perfect!! Neither are insurmountable things for a competent develoepr to add, but I'll re-post the script once II have the time to make my amendments.

    Feel free to use the alterations I posts on Page 1; they properly handle trust/untrust and enabled/disabled, using the best of your code from Check and FK constraints.
