Question

请考虑以下功能和函数调用：

create function [dbo].[GetCidrIpRange2](@CidrIp varchar(15))
returns @result table
(
    LowRange    varchar(15) not null,
    HighRange   varchar(15) not null,
    AddressQty  bigint not null
)
as
begin
    declare @Base       bigint  = cast(4294967295 as bigint)
    declare @Mask       int     = cast(substring(@CidrIp, patindex('%/%' , @CidrIP) + 1, 2) as int)
    declare @Power      bigint  = Power(2.0, 32.0 - @Mask) - 1
    declare @LowRange   bigint  = dbo.[IPAddressToInteger](left(@CidrIp, patindex('%/%' , @CidrIp) - 1)) & (@Base ^ @Power)
    declare @HighRange  bigint  = @LowRange + @Power

    insert @result
    select
         LowRange   = @LowRange
        ,HighRange  = @HighRange
        ,AddressQty = convert(bigint, power(2.0, (32.0 - @Mask)))
    return
end

select [dbo].[GetCidrIpRange2]('195.65.254.11/2');

我收到以下错误：

Cannot find either column "dbo" or the user-defined function or aggregate "dbo.GetCidrIpRange2", or the name is ambiguous.

名称是唯一的，当我只运行该函数时，它在会话中正确创建了函数：

Command(s) completed successfully.

我做错了什么？

Answer 1

您错过了FROM：

SELECT * FROM [dbo].[GetCidrIpRange2]('195.65.254.11/2');

为什么我的函数名称含糊不清？这不是imho？
