DESCRIBE VIEW

Describes the columns in a view (or table).

DESCRIBE can be abbreviated to DESC.

See also:

CREATE VIEW , SHOW VIEWS

DESCRIBE TABLE

Syntax

DESC[RIBE] VIEW <name>

Parameters

name

Specifies the identifier for the view 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

  • The command output does not include the view definition. Instead, use SHOW VIEWS.

  • DESC VIEW and DESCRIBE TABLE are interchangeable. Either command retrieves the details for the table or view that matches the criteria in the statement.

  • The output returns a POLICY NAME column to indicate the Column-level Security masking policy set on the column.

    If a masking policy is not set on the column or if the Snowflake account is not Enterprise Edition or higher, Snowflake returns NULL.

  • To post-process the output of this command, you can use the RESULT_SCAN function, which treats the output as a table that can be queried.

Examples

Example setup:

CREATE VIEW emp_view AS SELECT id "Employee Number", lname "Last Name", location "Home Base" FROM emp;

Describe the view:

DESC VIEW emp_view;
