CREATE_DATABASE Trigger to add a user

  • I'm trying to create a trigger that will add a user into the db_datareader role and I have my code below but it isn't working. What am I doing wrong and also how would I code this to have this trigger only fire if a certain naming convention is used for the a new database? For example the trigger will only fire when a database that has the name 'MY_DATABASE%' is created.

    /****** Object: DdlTrigger [Trigger_DB_Creation] Script Date: 02/02/2012 21:51:52 ******/

    SET ANSI_NULLS ON

    GO

    SET QUOTED_IDENTIFIER ON

    GO

    ALTER TRIGGER [Trigger_DB_Creation] ON ALL SERVER

    FOR CREATE_DATABASE

    AS

    CREATE USER FOR LOGIN

    GO

    EXEC sp_addrolemember N'db_datareader', N'USER'

    GO

    SET ANSI_NULLS OFF

    GO

    SET QUOTED_IDENTIFIER OFF

    GO

    ENABLE TRIGGER [Trigger_DB_Creation] ON ALL SERVER

    GO

  • Hello,

    Here you go :

    ALTER TRIGGER [Trigger_DB_Creation]

    ON ALL SERVER

    FOR CREATE_DATABASE

    AS

    BEGIN

    SET NOCOUNT ON

    DECLARE @event_data xml = EVENTDATA()

    , @database_name sysname

    , @sql nvarchar(1024)

    SELECT@database_name = @event_data.value('(/EVENT_INSTANCE/DatabaseName)[1]', 'sysname')

    SET @sql = 'USE ' + @database_name + ';'

    SET @sql = @sql + 'CREATE USER [myUser] FOR LOGIN [myLogin];'

    SET @sql = @sql + 'EXEC sp_addrolemember ''db_datareader'', ''myUser'''

    EXEC (@sql)

    END

  • What would be causing this error?

    SELECT failed because the following SET options have incorrect settings: 'ANSI_NULLS, QUOTED_IDENTIFIER'. Verify that SET options are correct for use with indexed views and/or indexes on computed columns and/or filtered indexes and/or query notifications and/or XML data type methods and/or spatial index operations. (Microsoft SQL Server, Error: 1934)

  • I added

    SET ANSI_NULLS ON

    SET QUOTED_IDENTIFIER ON

    and I'm still getting the error. Any thoughts?

  • Is there a way to have the trigger only fire when certain naming convention is used for a new database?
