Trigger and data type

  • I am really thankful to you Paul for your reply and alleviating my concern. It prompts me to explore more this 'B-tree structure' thing, quoted so much in the BOL and elsewhere. I can understand that B-tree is a computer science theory and SQL Server has its own implementation of this concept.

    Essentially, as GilaMonster said this is irrelevant to the access of the data through the DML queries. But this discussion is very helpful for me to be clear about the Physical Database Architecture. I did not pay much attention to it after completing My MCITP dev and admin (SQL Server 2005) last year because I am still into development side (database and applications) and am aspiring to to move into db admin side.

  • Thank you all,

    This Trigger works successfully:

    alter TRIGGER [TRG993]

    ON [dbo].[Source]

    AFTER INSERT

    AS

    BEGIN

    SET NOCOUNT ON;

    INSERT INTO DBntext2.dbo.Destination (Id, Title, Body)

    SELECT a.Id, a.Title, CAST(a.Body as nvarchar (MAX))

    FROM DBnetxt1.dbo.Source a, inserted b

    where a.Id = b.Id

    and now i have two questions:

    if DBntext1 and DBntext2 are in two diffrent Servers what should i do? How write T_QL Block?

    and the second question is that there are some fields in DBntext1 and i want to modify and then put in to DBntext2,

    in Server A.DBntext1.dbo.Source i have:

    ID( int) Title ( nvarchar(50) ) Body (ntext) Level 1(int ) Level 2 (int)

    1 a aa.... 1000 2000

    but i want to modify data of 2 fields(Level1 and Level2) and then put them in the Server B.DBntext2.dbo.Destination

    Server B.DBntext2.dbo.Destination i want to have :

    ID( int) Title ( nvarchar(50) ) Body (nvarchar(max)) Level 1(int ) Level2

    1 a aa.... 1 2

    *** ***

    How should i write the The T_SQL Block?
