    What's New in SQL Server 2005 SP2

    Printre altele un nou tip de date vardecimal.

    "Note: Vardecimal is a storage format, not a data type. [...] To enable vardecimal storage format for decimal data types using Management Studio, use the Database Properties Options Page to enable the vardecimal storage format in the database, and then use the Table Properties General Page, to enable the vardecimal storage format in the appropriate tables."

    "Use the vardecimal storage format when you have a shortage of disk space, when disk access (I/O) is a bottleneck on system performance, or when you require a high level of precision for some of the data, even though many of the values are small, NULL, or zero (such as a table in a data warehouse with a decimal column that has many rows contain zero or integer values)."

    "Databases using vardecimal storage format must be set to the simple recovery model."

    Re: SP2 CTP

    M-am entuziasmant prea tare si m-am grabit! Un nou tip de stocare nu un nou tip de date.

    Desi citind descrierea din Books Online

    When the vardecimal storage format is enabled on a table, the decimal data is stored in the data, index, and log pages in the vardecimal storage format.
    se poate spune ca e un nou tip de date.

    Pana si Microsoft spune asta SQL Server Engine Tips : Download SQL Server 2005 SP2 CTP

    SQL Server 2005 SP2 CTP contains some new features in the database engine (vardecimal data types, object_name function enhancement, logon triggers, Common Criteria Compliance, sys.dm_exec_text_query_plan DMV, plan cache improvements among others).

    Re: SP2 CTP

    O noua functionalitate care mi-a atras atentia este "logon triggers".

    Re: SP2 CTP

    Un lucru care nu mi-a sarit in ochi citind Books Online pe subiectul "vardecimal" este ca nu merge pe editia Standard, iata dovada:

    USE master ;
    GO

    EXEC sp_db_vardecimal_storage_format 'AdventureWorks', 'ON' ;

    GO

     --output

    Msg 1844, Level 16, State 2, Line 1

    Vardecimal Storage Format is not supported on Standard Edition.

    sp_db_vardecimal_storage_format statement failed.

    Re: SP2 CTP

    Pentru ca "vardecimal" este un format de storage (vezi remarca lui Razvan de mai sus) cred ca poti incerca din ADO.NET cu System.Data.SqlTypes.SqlDecimal. Ar fi si o "analogie" cu "char" si "varchar" care "corespund" cu System.Data.SqlTypes.SqlString.
  •  07-13-2007, 10:35 AM 2241 in reply to 2240

    Re: SP2 CTP

    Diana, analogia e un pic forţată, deoarece char şi varchar sunt tipuri de date diferite în SQL Server (care corespund întâmplător cu acelaşi tip de date .NET), însă în cazul lui decimal e vorba de un singur tip de date în SQL (care într-adevăr ar trebui să corespundă cu System.Data.SqlTypes.SqlDecimal) şi doar de moduri de stocare diferite. De fapt, eu cred că motivul pentru care Microsoft a optat să fie un "storage format", nu un nou "data type" este tocmai acesta: să nu fie nevoie de nicio modificare în aplicaţii.
