sys.external_job_streams (Transact-SQL)sys.external_job_streams (Transact-SQL)

为映射到外部流式处理作业的输入或输出外部流对象返回一行。Returns a row each for the input or output external stream object mapped to an external streaming job.

列名称Column name 数据类型Data type 说明Description
job_idjob_id intint 流式处理作业对象的对象标识号。Object identification number for the streaming job object. 此列映射到 sys.external_streaming_jobs 的 object_id 列。This column maps to the object_id column of sys.external_streaming_jobs.
stream_idstream_id intint 流对象的对象标识号。Object identification number for the stream object. 此列映射到 sys.external_streams 的 object_id 列。This column maps to the object_id column of sys.external_streams.
is_inputis_input bitbit 如果将流对象用于流式处理作业的输入,则为 1;否则为 0。1 if the stream object is used an input for the streaming job, otherwise 0.
is_outputis_output bitbit 如果将流对象用于流式处理作业的输出,则为 1;否则为 0。1 if the stream object is used an output for the streaming job, otherwise 0.

示例Example

此目录视图与 sys.external_streamssys.external_streaming_jobs 目录视图一起使用。This catalog view is used together with sys.external_streams and sys.external_streaming_jobs catalog views. 以下显示了一个查询示例A sample query is shown below

Select
    sj.Name as Job_Name,
    sj.Create_date as Job_Create_date,
    sj.modify_date as Job_Modify_date,
    sj.statement as Stream_Job_Query,
    Input_Stream_Name =
        Case js.is_input
            when 1 then s.Name
            else null
        END,
    output_Stream_Name =
        case js.is_output
            when 1 then s.Name
            else null
        END,
    s.location as Stream_Location
from sys.external_job_streams js
inner join sys.external_streams s on s.object_id = js.stream_id
inner join sys.external_streaming_jobs sj on sj.object_id = js.job_id
