DESCRIBE DATABASE¶
描述数据库。例如,显示数据库中的架构。
DESCRIBE 可以缩写为 DESC。
小技巧
除了 SQL,您还可以使用其他接口,如 Snowflake REST APIs、Snowflake Python APIs 和 Snowflake CLI。请参阅 备用接口。
- 另请参阅:
ALTER DATABASE、CREATE DATABASE、DROP DATABASE、SHOW DATABASES、UNDROP DATABASE
DATABASES 视图 (Information Schema)
语法¶
DESC[RIBE] DATABASE <database_name>
参数¶
database_name指定要描述的数据库的 :doc:` 标识符 </sql-reference/identifiers>`。
使用说明¶
To post-process the output of this command, you can use the pipe operator (
->>) or the RESULT_SCAN function. Both constructs treat the output as a result set that you can query.The output column names for this command are generated in lowercase. If you consume a result set from this command with the pipe operator or the RESULT_SCAN function, use double-quoted identifiers for the column names in the query to ensure that they match the column names in the output that was scanned. For example, if the name of an output column is
type, then specify"type"for the identifier.
示例¶
此示例演示了 DESCRIBE DATABASE 命令:
CREATE DATABASE desc_demo;
CREATE SCHEMA sample_schema_1;
CREATE SCHEMA sample_schema_2;
DESCRIBE DATABASE desc_demo;
