DESCRIBE VIEW | Snowflake Documentation

Describes the columns in a view (or table).

DESCRIBE can be abbreviated to DESC.

See also:

DROP VIEW , ALTER VIEW , CREATE VIEW , SHOW VIEWS

DESCRIBE TABLE

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.

• 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 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 pipe operator or the RESULT_SCAN function. Both constructs treat the output as a result set that you can query.

Example setup:

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