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：
