Recall that users with the load authority also require the insert privilege to load data into a table and the delete privilege if the load operation is defined as replace 如果load操作定义为replace ,那么具有load权限的用户还需要insert特权(为了将数据装载到表中)和delete特权。
The possible reasons are as follows ; discharge valve damage or over load operation of diesel engine , or leakage of nozzle , or the incomplete combustion in the cylinder because not enough fresh air was pumped 可能的原因如下;排气阀损坏或柴油机超负荷运转,或油嘴漏泄,或由于进气量不足导致燃烧不完全,等等。
Bill of lading : is the official document , issued at the loading port after completing of the loading operations , stating , among other things , the ship ' s loaded quantity expressed in , metric tons ( mt ) per the definitions herein 提单:是正式文件,在装运港完成运输后盖章,它规定了船只装载量,用上面解释过的mt来表示单位数量。
Integration services overview integration services is a platform for building high performance data integration and workflow solutions , including extraction , transformation , and loading operations for data warehousing Integration services是用于生成高性能数据集成和工作流解决方案(包括针对数据仓库的提取、转换和加载( etl )操作)的平台。
The model is to plan quay - crane loading operation , to schedule yard - crane routing and to dispatch vehicles to containers , so as to minimize the totally idle time of the related equipment and yard - crane travel time 模型对岸桥装载规划、堆场起吊设备路径选择和集卡分配进行了系统的优化,其优化目标是相关设备的空闲和堆场起吊设备空驶时间的最小化。
This paper involves qualitative analysis to inclined belt conveyor for gantry bucket wheel stacker - reclaimer . the component structures and working characters are improved , accomplishing full load operation of the stacker - reclaimer 摘要通过对门式斗轮堆取料机斜升带式输送机的定性研究分析,从改变部件结构和部件工作特性人手,对其进行了改进,实现了门式斗轮堆取料机的满负荷运行。
With the development of electric power industry , it is required that higher dependability to the electric equipment . to improving the peak load capacity of power network , it is the trend that the large capacity steam turbine units take part in peak load operation 电力工业的发展,对机组设备的可靠性提出了更高的要求,大容量机组参与调峰运行更是提高电网调峰能力的必然趋势。
Abstract : the paper analyzes and diagnoses over load operation of 250 heating furnace fan motor at kungang , so real causes are judged correctly . some correspondent measures are taken to satisfy basically the needs of heating furnace operation and steel - rolling production , and avoid occurrence of the equipment accident 文摘:通过对昆钢250加热炉风机电机过负荷运行的分析诊断,正确判断出真正原因,并采取相应措施,基本满足了加热炉运行和轧钢生产的需要,避免了设备事故的发生。
Although oil is used only in the case of ignition and low load operation , the amount is very great . in order to save the precious and expensive oil , a novel technology , induction - heating multi - stage free - oil ignition technology of pulverized coal ( mfit ) , is brought forward in this thesis . based on the study of ignition mechanism of coal , ignition criterion , heating method and ignition theory of pulverized coal ( pc ) , mfit integrates hot - wall ignition technology , induction heating technology and multi - stage ignition technology 为降低电站锅炉点火成本和低负荷运行费用、解决电站锅炉点火用油和低负荷助燃用油居高不下的问题,在分析研究煤的着火机理、着火判据、加热方式和煤粉的点燃理论的基础上,本文将热壁面点火、感应加热、多级点火等过程有机地结合起来,进行了感应加热煤粉多级无油点火的试验研究。
