The parameter copies all privileges, except OWNERSHIP, from the existing view to the new view. Retains the access permissions from the original view when a new view is created using the OR REPLACE clause. If the USING clause is omitted, Snowflake treats the conditional masking policy as a normal When a query is made on the first column. The additional columns specify the columns to evaluate to determine whether to mask or tokenize the data in each row of the query result The first column in the list specifies the column for the policy conditions to mask or tokenize the data and must match theĬolumn to which the masking policy is set.

For example, the column names are required in the following case:Ĭomments are particularly helpful when column names are cryptic. If any of the columns in the view are based on expressions (not just simple column names), then you must supplyĪ column name for each column in the view. (You do not need to specify the data types of the columns.)

If you drop the view, you drop the temporary view, and not the view The temporary view in the session, until you drop the temporary view. If you created a temporary view with the same name as another view in the schema, all queries and operations used on the view only affect If you want to avoid unexpected conflicts, avoid naming temporary views after views that already exist in the schema.
