Free Template to Quickly Create Views in Snowflake

If you need a quick way to create views in Snowflake, this template allows you to save a stored procedure that you can call any time to create views and permission roles for them. Enjoy!

Step 1 - Create View Template stored procedure

Run the following stored procedure in your Snowflake account, as ACCOUNTADMIN.

Copy Text

CREATE OR REPLACE PROCEDURE ADD_MASKING(DBNAME VARCHAR, SCHEMANAME VARCHAR, TABLENAME VARCHAR, COLUMNNAME VARCHAR, ROLENAME VARCHAR) 

RETURNS STRING 

LANGUAGE JAVASCRIPT 

VOLATILE 

EXECUTE AS CALLER 

AS $$ 

  function execQuery(queryString) { 

    return snowflake.execute({sqlText:queryString}); 

  } 

  // This script must execute as ACCOUNTADMIN so that 

  // we can grant the target role permissions on objects 

  // that the target role may not even be able to see. 

  try { 

    execQuery("USE ROLE ACCOUNTADMIN"); 

  } catch (error) { 

    return 'You must call this stored procedure with a user and role that can assume role ACCOUNTADMIN: ' + error; 

  } 


  //try to append to masking policy if it exists 

  try { 

    //get masking policies 

    var masks = execQuery(`SHOW MASKING POLICIES;`); 

    var name = execQuery(`select "name" as NAME from table(result_scan(last_query_id())) WHERE NAME='SP_FULL_MASK_${COLUMNNAME}'`); 

     

    if (name.getRowCount() != 0) 

    { 

      var result = execQuery(`DESCRIBE MASKING POLICY SP_FULL_MASK_${COLUMNNAME};`); 

      result.next(); 

      var maskingBody = result.getColumnValueAsString('body'); 

 

      //if not already in the masking policy 

      if (maskingBody.indexOf(ROLENAME) == -1) 

      { 

        //insert it in the masking Body 

        //find first when 

        var index = maskingBody.indexOf('when'); 

        maskingBody = maskingBody.slice(0, index) + `when current_role() in ('${ROLENAME}') then '*********'\n\t\t` + maskingBody.slice(index); 

        //alter the masking policy 

        execQuery(`alter masking policy if exists SP_FULL_MASK_${COLUMNNAME} set body -> ${maskingBody}`); 

        return `Successfly added role ${ROLENAME} to mask`; 

      } 

      else { 

        return `Column ${COLUMNNAME} is already masked for ${ROLENAME}`; 

      } 

       

    }   

     

  } catch (error) { 

    return error; 

  } 

 

  //create masking policy if it doesn't exist 

  try { 

    execQuery(` 

      create masking policy if not exists SP_FULL_MASK_${COLUMNNAME} as (val string) returns string -> 

      case 

        when current_role() in ('${ROLENAME}') then '*********' 

        else val 

      end;` 

    ); 

    //apply the policy 

    execQuery(`alter table if exists ${DBNAME}.${SCHEMANAME}.${TABLENAME} modify column ${COLUMNNAME} set masking policy SP_FULL_MASK_${COLUMNNAME};`); 

     

    return `Successfly masked column ${COLUMNNAME} for role ${ROLENAME}`; 

  } catch (error) { 

    return error; 

  } 

  

  return `Successfly masked column ${COLUMNNAME} for role ${ROLENAME}`; 

$$;

Step 2 - Create views!

Call the stored procedure, substituting your own database, schema, table, and column names, as well as the Role that should have access to the view. Once run, the view will be created and role will have access to the view automatically!
