DESCRIBE VIEW¶

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 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.

  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.

Examples¶

Example setup:

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

Copy

Describe the view:
