备注

Every major object in Microsoft SQL Server 2005 Analysis Services (SSAS) has an ID element as a property. The value of an ID element has the following restrictions:

  • The value cannot contain leading or trailing spaces. Analysis Services will implicitly remove leading or trailing spaces from the value of an ID element.
  • The value cannot contain control characters. Analysis Services will implicitly remove control characters from the value of an ID element.
  • The following reserved values cannot be used:
    • AUX
    • CLOCK$
    • COM1 through COM9 (COM1, COM2, COM3, and so on)
    • CON
    • LPT1 through LPT9 (LPT1, LPT2, LPT3, and so on)
