类别：: 系统函数（系统信息）

SYSTEM$CLIENT_VERSION_INFO¶

返回 Snowflake 客户端和驱动程序的版本信息。

另请参阅：: 客户端版本和支持策略

语法¶

SYSTEM$CLIENT_VERSION_INFO()

实参¶

无

返回¶

返回一个包含对象 JSON 数组的字符串。每个对象都包含有关特定客户端和驱动程序的信息，例如 SnowSQL、JDBC 驱动程序等。

每个 JSON 对象都包含以下名称/值对：

{
  "clientId": "DOTNETDriver",
  "clientAppId": ".NET",
  "minimumSupportedVersion": "2.0.9",
  "minimumNearingEndOfSupportVersion": "2.0.11",
  "recommendedVersion": "2.1.5",
  "deprecatedVersions": [],
  "_customSupportedVersions_": []
},

其中：

clientId
客户端或驱动程序的内部 ID。可能的值包括：

DOTNETDriver

GO

JDBC

JSDriver

ODBC

PHP_PDO

PythonConnector

SnowSQL

SQLAPI

clientAppId
客户端或驱动程序的名称。可能的值包括：

.NET

GO

JDBC

JavaScript

ODBC

PDO

PythonConnector

SnowSQL

SQLAPI

minimumSupportedVersion
官方支持的最早版本的客户端或驱动程序。

minimumNearingEndOfSupportVersion
在下一季度初达到支持终止日期 (EOS) 的客户端或驱动程序的版本。

recommendedVersion
客户端或驱动程序的当前版本。

deprecatedVersions、_customSupportedVersions_
仅供内部使用。

使用说明¶

如果您不想处理 JSON，则可以使用 PARSE_JSON 和 LATERAL FLATTEN 函数，将 JSON 转换为列式输出。
您也可以使用 WHERE 子句返回特定客户端或驱动程序的信息 (clientId)。

示例¶

以下示例会检索所有 Snowflake 客户端和驱动程序的版本信息。请注意，为了提高可读性，输出已手动格式化。

SELECT SYSTEM$CLIENT_VERSION_INFO();
