语句statement varchar(max)varchar(max) 流式处理作业的流分析查询文本。The stream analytics query text for the streaming job. 有关详细信息,请参阅 sp_create_streaming_jobFor more information, see sp_create_streaming_job
statusstatus intint 流式处理作业的当前状态。The current status of the streaming job. 可能的值包括The possible values are

已创建 = 0。Created = 0. 流式处理作业已创建,但尚未开始。The streaming job was created, but has not yet been started.

正在启动 = 1。Starting = 1. 流式处理作业处于开始阶段。The streaming job is in the starting phase.

失败 = 6。Failed = 6. 流式处理作业失败。The streaming job Failed. 这通常表示在处理过程中出现灾难性错误。This is generally an indication of a fatal error during processing.

已停止 = 4。Stopped = 4. 流式处理作业已停止。The streaming job has been stopped.

空闲 = 7。Idle = 7. 流式处理作业正在运行,但没有要处理的输入。The streaming job is running, however there is no input to process.

正在处理 = 8。Processing = 8. 流式处理作业正在运行,且正在处理输入。The streaming job is running, and is processing inputs. 此状态指示流式处理作业的正常运行状态。This state indicates a healthy state for the streaming job.

已降级 = 9。Degraded = 9. 流式处理作业正在运行,但在输入处理期间出现一些非致命的输入/输出序列化/反序列化错误。The streaming job is running, however there were some non-fatal input/output serialization/de-serialization errors during input processing. 输入作业将继续运行,但将删除遇到错误的输入。The input job will continue to run, but will drop inputs that encounter errors.
