DESCRIBE STAGE¶
Describes the values specified for the properties in a stage (file format, copy, and location), as well as the default values for each property.
DESCRIBE can be abbreviated to DESC.
- See also:
Syntax¶
DESC[RIBE] STAGE <name>
Parameters¶
nameSpecifies the identifier for the stage to describe. If the identifier contains spaces or special characters, the entire string must be enclosed in double quotes. Identifiers enclosed in double quotes are also case-sensitive.
Usage notes¶
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.
Output¶
The command output provides stage properties and metadata in the following columns.
Column |
Description |
|---|---|
|
The parent property to which each stage property belongs. Possible values include STAGE_FILE_FORMAT, STAGE_COPY_OPTIONS, STAGE_LOCATION, STAGE_CREDENTIALS, and DIRECTORY. |
|
The name of the property. For property descriptions, refer to CREATE STAGE. |
|
The property type. |
|
The value assigned to the property. |
|
The default property value. |
Note
For stages with a directory table, the output includes a property named LAST_REFRESHED_ON of type TIMESTAMP. LAST_REFRESHED_ON indicates when the metadata for the directory table was last synchronized with the associated files on the stage, either manually or automatically.
Examples¶
Describe an internal stage named my_s3_stage:
