CodeGen CreateFile实用程序

CodeGen CreateFile实用程序

CreateFile实用程序允许根据存储库文件或结构定义创建ISAM文件。

CreateFile实用程序的命令行选项如下：

CreateFile -f <fname> | -s <sname> [-out filespec] [-r] [-h]

-f <fname>   

          Name of
repository file definition to process.

-s <sname>

          The name of
the repository structure definition to process.

-in <infile>

          Name of JSON
input file containing the details of file(s) to create.

-out <filespec>

          File
spec of file to create, overriding repository file spec. Not used with -in.

-r    Replace existing files. The default is not to replace
existing files. Not used with -in.

-h    Display this usage information.

当基于存储库文件定义创建文件时，密钥规范将由分配给该文件的第一个结构中定义的键确定。当基于存储库文件结构创建文件时，文件规范将由分配给该结构的第一个文件确定。CreateFile假定存储库键定义的定义顺序与它们引用的键相同。假设第一个定义的键是主键，第二个键（如果有的话）是第一个备用键，依此类推。

-f和-s选项只能用于创建ISAM文件。-in选项可用于创建ISAM和相关文件，但只有在提供包含初始数据的输入文件时才能创建相关文件。

与-in选项一起使用的输入文件必须是类似于以下内容的JSON文件：

[

    {

     
"RepositoryFileName": "CUSTOMER",

      "CreateFile":
"DAT:CUSTOMER.ISM",

      "LoadFromFile":
"TESTDATA:CUSTOMER.TXT",

     
"OverwriteExistingFile": true

    },

    {

     
"RepositoryFileName": "OPTIONS",

      "CreateFile":
"DAT:OPTIONS.DDF",

      "LoadFromFile":
"TESTDATA:OPTIONS.TXT",

     
"OverwriteExistingFile": false

    }

  ]

包括“CreateFile”是可选的。默认情况下，使用存储库文件定义的文件规范。

对于ISAM文件，包含“LoadFromFile”是可选的，如果没有提供，将创建一个空文件。对于相对文件，必须提供一个初始数据文件，并且该文件必须至少包含一个适当长度的记录。              包括“OverwriteExistingFile”是可选的。默认情况下，文件不会被覆盖。

Example
1

C:\> createfile
-f CUSTFIL

DAT:customer.ism
-> File created.

Example 2

C:\> createfile
-s CUSTOMER

DAT:customer.ism
-> File created.

Example 3

C:\> createfile
-f CUSTFIL -f DAT:customer_save.ism

DAT:customer_save.ism
-> File created.

Example 4

C:\> CreateFile
-in CreateAndLoadFiles.json

Where CreateAndLoadFiles,json
contains:

[

{

"RepositoryFileName": "MEMBERS",

"CreateFile": "CUFILES:MEMB01.DDF",

"LoadFromFile": "SEQ:MEMB01.SEQ",

"OverwriteExistingFile": true

},

{

"RepositoryFileName": "ACCOUNTS",

"CreateFile": "CUFILES:MEMB02.DDF",

"LoadFromFile": "SEQ:MEMB02.SEQ",

"OverwriteExistingFile": true

},

{

"RepositoryFileName": "PERSONS",

"CreateFile": "CUFILES:PERMST.DDF",

"LoadFromFile": "SEQ:PERMST.SEQ",

"OverwriteExistingFile": true

},

{

"RepositoryFileName": "CHCARD",

"CreateFile": "CUFILES:CHCARD.DDF",

"LoadFromFile": "SEQ:CHCARD.SEQ",

"OverwriteExistingFile": true

},

{

"RepositoryFileName": "TRANSMAS",

"CreateFile": "CUTRX:TRANSMAS.DDF",

"LoadFromFile": "SEQ:TRANSMAS.SEQ",

"OverwriteExistingFile": true

},

{

"RepositoryFileName": "OPTIONS",

"LoadFromFile": "SEQ:OPTIONS.SEQ",

"OverwriteExistingFile": true

}

]

输出如下：
