The Structured Query Language (SQL) has been in use for over 30 years with various types of database technologies. However, there is no current media type registered for SQL. Therefore, this document seeks to formally register the application/sql media type to be used for SQL with IANA.
结构化查询语言（SQL）已经在各种类型的数据库技术中使用了30多年。但是，没有为SQL注册的当前媒体类型。因此，本文档旨在向IANA正式注册用于sql的应用程序/sql介质类型。
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119] when they appear in ALL CAPS. These words may also appear in this document in lowercase as English prose, absent of the normative meanings mentioned above.
本文件中的关键词“必须”、“不得”、“要求”、“应”、“不得”、“应”、“不应”、“建议”、“可”和“可选”在所有大写字母中出现时，应按照[RFC2119]中的说明进行解释。这些词语也可能以英文散文形式以小写形式出现在本文件中，不具有上述规范性含义。
This section provides the media type registration application for this media type (see [RFC6838], Section 5.6)
本节提供了该介质类型的介质类型注册应用程序（见[RFC6838]，第5.6节）
Type name: application
类型名称：应用程序
Subtype name: sql
子类型名称：sql
Required parameters: N/A
所需参数：不适用
Optional parameters:
可选参数：
"charset" -- indicates the character set to be used. When not specified, a default value MUST NOT be assumed without inspection of the content.
“字符集”--表示要使用的字符集。未指定时，在未检查内容的情况下，不得假定默认值。
Implementors should be aware that SQL may carry character set information in-band. In such cases, the "charset" parameter MUST NOT be used in order to avoid conflict. In cases where no character set information is supplied in-band, and the character
实现者应该知道，SQL可能在频带中携带字符集信息。在这种情况下，不得使用“charset”参数以避免冲突。在频带中未提供字符集信息的情况下
set is known, implementors SHOULD use the "charset" parameter. If no in-band or out-of-band character set information is available, implementors MUST NOT specify the "charset" parameter.
如果已知该集合，则实现者应使用“charset”参数。如果没有带内或带外字符集信息可用，则实现者不得指定“charset”参数。
Encoding considerations:
编码注意事项：
If the "charset" parameter is used, the corresponding 7-bit, 8-bit, or binary encoding may be used. If the "charset" parameter is not used, binary encoding may be required.
如果使用“charset”参数，则可以使用相应的7位、8位或二进制编码。如果未使用“charset”参数，则可能需要二进制编码。
Security considerations:
安全考虑：
Being that SQL is a full-fledged programming language and may include embedded source code for other programming languages, there is a risk of it being used to transfer malware, viruses, and other malicious payloads. Implementors and users are encouraged only to exchange SQL files among trusted parties and utilize all available security measures, such as restricted access, virus scanners, etc., to minimize risk.
由于SQL是一种成熟的编程语言，可能包含其他编程语言的嵌入式源代码，因此它有被用于传输恶意软件、病毒和其他恶意有效负载的风险。我们鼓励实施者和用户仅在受信任方之间交换SQL文件，并利用所有可用的安全措施，如限制访问、病毒扫描等，以将风险降至最低。
Implementors should be aware that guessing character sets, encodings, and possible conflicts between in-band and out-of-band character set information may lead to the similar security issues as described above.
实现者应该知道，猜测字符集、编码以及带内和带外字符集信息之间可能存在的冲突可能会导致上述类似的安全问题。
Implementors should also be aware that SQL does not provide or guarantee any sort of confidentiality and integrity checking, and SQL files can expose account information or private information about database structure and contents. It is therefore important for applications to provide confidentiality and protection against modification by malicious third parties while in transit.
实现者还应该知道，SQL不提供或保证任何类型的机密性和完整性检查，SQL文件可以公开帐户信息或有关数据库结构和内容的私有信息。因此，对于应用程序来说，在传输过程中提供机密性和防止恶意第三方修改非常重要。
Interoperability considerations:
互操作性注意事项：
While a single standard exists ([ISO.9075.2011]), vendor implementations of the standard vary significantly. Implementors and users should make sure that the exchanged SQL files match to the specific database/tool and version that they are using.
虽然存在单一标准（[ISO.9075.2011]），但供应商对该标准的实施情况差异很大。实现者和用户应该确保交换的SQL文件与他们使用的特定数据库/工具和版本相匹配。
Published specification:
已发布的规范：
The most recent specification of SQL is available in [ISO.9075.2011].
SQL的最新规范见[ISO.9075.2011]。
