Using a sequential file for input, LOAD can add rows to a brand-new empty table or to an already-populated table. 使用一个顺序文件作为输入,LOAD可以将行添加到全新的空表或已填充的表。
The sequential index, which suffixes the file name, is generated by the binding and stored in the file specified by "Sequence file". 作为文件名后缀的顺序索引由绑定生成,且存储在“Sequencefile”指定的文件中。
You need to edit the Sequential File stage to identify the comma-delimited file that contains the input data. 需要编辑SequentialFile阶段以识别以逗号分隔的包含输入数据的文件。
The program then changes the column data ( usually by reading a sorted transaction file in the same order as the table data) and writes both the changed and unchanged rows to a sequential file. 然后,该程序更改列数据(通常通过将相同顺序的已排序事务文件读作表数据),并将已变更和未变更的行写入一个顺序文件。
( This sort might be needed if the column data on which the table is clustered is changed.) The output sequential file can then be used as input to the LOAD utility. (如果集群化表格所在的列数据被更改,可能会需要此类排序。)输出的顺序文件可以用作LOAD实用程序的输入。
J2_maxPageReadAhead: This determines the maximum amount of pages that VMM can read in a sequential file. J2maxPageReadAhead:这个参数用于确定VMM可以在一个顺序文件中读取页面的最大数量。
Double-click on the icon representing the Sequential File stage. 双击代表SequentialFile阶段的图标。
In this scenario, the XML stage filters out only the home address from the input XML file, then maps the entire employee information to a single output sequential file. 在该场景中,XMLstage从输入XML文件中仅过滤出家庭住址,然后将整个员工信息映射到单一输出顺序文件。
A higher sequentiality tells you that the files are more contiguously allocated, which will also be better for sequential file access. 较高的顺序性意味着文件的分配具有更高的连续性,当然这对于顺序文件访问更加有利。
In the output step, the employee information needs to be mapped to the output sequential file. 在输出步骤中,需要将员工信息映射到输出顺序文件。
After the program finishes, the sequential file can be sorted if necessary. 在执行完该程序后,如有必要,可以对顺序文件进行排序。
The job is designed to combine data from two sequential files into an XML file, and the XML file is then written into a column in the database. 该作业旨在将来自两个连续文件的数据合并为一个XML文件,且该XML文件将被写入数据库中的列。
Higher space efficiency means files are less fragmented and provide better sequential file access. 较高的空间效率意味着文件出现较少的碎片,并且提供更好的顺序文件访问。
The transaction log is stored as a sequential disk file ( or sometimes in a raw partition) and will generally only be written to, not read from, except in the case of rollback or recovery. 事务日志存储为连续的磁盘文件(有时存储在原始分区中),并且一般只是用于写入而不用于读取,回滚或恢复的情况例外。
Sequential file of variable length record 可变长度记录顺序文件
Sequential mass storage file 按序大容量存储器文件
The amount of space to be allocated at the end of a file each time a sequential write exceeds the allocated length of the file. 当顺序写操作超出文件原长度时,在文件末端另分配给该文件的空间量。
If batch processing is acceptable, a sequential file organization is probably best. 如果可采用批处理的话,那么一个顺序文件结构可能是最好的了。
Abstract This paper describes a method used to directly access individual entries in the dictionary which is a large sequential file containing variable length records. 本文叙述了用于直接访问由可变长记录组成的顺序式词典文件中各个词条的一种方法。

Statement specifies a sequential file. 语句指定了一个顺序文件。
A table used to locate records in an indexed sequential data set or an indexed file. 用来查找索引顺序数据集或索引文件中的记录的一种表。
Aimed at TDRMS's specialty, a storage system design method based on sequential access media is proposed, then an algorithm used for speech data file query is proposed too. 针对电话录音监控系统应用的特点,提出了一种基于顺序存储介质&磁带的电话语音数据存储系统设计方法,并给出了在该系统下进行语音数据文件查询的算法。
New Method for Password Setting by Using VB Sequential File 利用VB顺序文件实现口令密码的新方法
Based on a deep analysis of the function parallelism of conventional sequential and inverted file retrieval, the paper presents the principle and procedure of parallel algorithms for sequential and inverted file retrieval provided that a homogeneous MIMD computer system is employed. 本文在较深入地分析传统的顺排检索和倒排检索中的功能并行性之后,基于同构型MIMD计算机系统,研究并提出并行顺排检索和并行倒排检索的算法原理及过程。
According to the structural principle of the encoding template and generating binary pseudo-random sequential code by computer, pattern file is generated with language C based on encoding mode, thus the encoding template is lithographed. 根据编码模板的构造原理,通过计算机生成二元伪随机序列码,用C语言根据编码方式生成图形文件,进而光刻出编码模板。
Approach to the Parallelism for Sequential and Inverted File Retrieval 关于顺排检索和倒排检索的并行化探讨
In sequential access condition, fast media file system is more efficient than traditional NTFS. 在视频文件顺序访问的条件下,快速多媒体存储文件系统比传统NTFS文件系统效率更高。
