Conventions used
There are a number of text conventions used throughout this book.
Code in text
: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "We will start by simply selecting all rows from the QUERY_HISTORY
view."
A block of code is set as follows:
CREATE TRANSIENT SCHEMA temporary_data DATA_RETENTION_TIME_IN_DAYS = 0 COMMENT = 'Schema containing temporary data used by ETL processes';
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
USE ROLE ACCOUNTADMIN; USE SNOWFLAKE; SELECT QUERY_ID, QUERY_TEXT, EXECUTION_TIME,USER_NAME FROM SNOWFLAKE.ACCOUNT_USAGE.query_history ORDER BY EXECUTION_TIME DESC;
Any command-line input or output is written as follows:
$ mkdir css $ cd css
Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
