Let's first create a stage. A stage is a logical concept or an abstraction of a filesystem location that is external or internal to Snowflake. In this case, an external stage has been used. The location can be managed in one of the object stores supported by the underlying cloud storage. In the case of AWS, S3 is used for this purpose. This recipe uses S3. The following statement creates a stage named sfuser_ext_stage. The stage should be accessible to Snowflake: CREATE OR REPLACE STAGE sfuser_ext_stage Let's now look at how the parquet file can be loaded into an external table. We shall be creating an external table called ext_tbl_userdata1. The creation of the table would require a location from which data can be read into the table. It would also require a file format. In this case, the file type is parquet: create or replace external table ext_tbl_userdata1 Enchantment rings through the book and is found in the self-mythologising of the characters, the classical references and the focus on the self and identity. The splendour of Trinity is overshadowed by the mysticism of the farm, where calves are born deformed, sometimes with no head or extremities, and where lives are snuffed out.

This is a description of the local therapist in Debbie’s home town. There are so many problems in these two sentences alone. The ONE thing everyone loves? Everyone? And is that really Audrey’s problem? Or is it the problem of the people around her? In addition, this is presented as received wisdom from Debbie’s neighbours. Debbie does not question this in any way. Yet she’s apparently very smart? I guess in the ‘I am very intelligent’ meme sense only. Debbie White grew up milking cows on a dairy farm in Kildare, with her uncle Billy living in a caravan on the property and her mother Maeve living in her dreams, sleeping the days away. When she’s accepted to study English in Trinity College Dublin, she swaps the brutality of farm life for that of the city, where guards laugh at her for asking for directions and classmates sneer at her naiveté. This recipe will introduce you to different variations of views that are specific to Snowflake and in what scenario a variant of a view should be used. The recipe will cover simple views and materialized views and will provide guidance on when to use what type of view. Getting readyThis recipe shows you how to create a table and insert data to explain different behaviors in storing data. Here you will be introduced to the different options that are available from a life cycle perspective, such as tables being permanent, temporary, volatile, and so on. Most of the concepts are not new, so the focus is going to be on the specifics related to Snowflake. We will start with a simple example that creates a table. We shall insert some sample data into it and then try out different variations on creating tables in Snowflake. Getting ready The preceding SQL script will allow you to create two tables, customers_temp and customers_trans. The two tables are not permanent, but the tables have limitations. If you end the web UI session at this point, then the customers_temp table will not be recoverable after a re-login. Transient tables are available after a session has been closed and will retain data in a subsequent session created by user login; however, they don't consume fail-safe storage. This is an important mechanism for retaining data across sessions and can have applications in scenarios that require state management or in ETL jobs. CREATE TRANSIENT TABLE customers_trans AS AS SELECT * FROM customers WHERE TRY_TO_NUMBER(postal_code) IS NULL;

From there, Nealon asks how we discover who we are once we venture out on our own, as Debbie struggles to find herself, while avoiding turning into her mother. this is another contemporary, coming of age tale which follows debbie, an 18 year old who lives on a dairy farm as she navigates her 1st year at university, while also trying to handle her eccentric and troubled mother and uncle. if you know me you know i love a coming of age story, so this premise was right up my street. the writing was beautiful and lyrical but also raw, perfectly capturing the mindset of what it’s like to be a young woman figuring out life and trying to survive university (perfect for fans of sally rooney and naosie dolan in that regard). it also had a small magical realism element related to dreams which i definitely think added something unique to the story, even though i do wish it was developed a bit more. i also really enjoyed the irish slang in the dialogue and the exploration of some of the folklore, i found it all so interesting to read about! nealon also touches on several themes in this book too, like mental illness, family dynamics, friendship, identity, alcoholism, the pressure of university, and more.For schemas that will store temporary tables, such as tables used for ETL processing, a schema can be created as a transient schema, which means that there is no fail-safe storage associated with the tables created in the schema, and therefore it would cost less. Similarly, such schemas can also be set to have time travel set to zero to reduce costs further. By default, the time travel for transient schemas is 1 day.

The output of SHOW DATABASES would show retention_time as zero, indicating that there is no time travel storage for this database, and also the options column would show TRANSIENT as the option, which essentially means that there will be no fail-safe storage for this database. Stars | SNOWFLAKE BY LOUISE NEALON is the coming-of-age story you (probably) didn’t know you needed (or maybe you already knew). If you’ve been following my stories, you’d know how much i’d been taken by it - and it’s all for good reasons! I inspect what I just squirted out of myself before I flush it away. Foam fizzed on top of the watery gold like froth on a pint.”

The story revolves around Debbie, the narrator, who is embarking on her university years. She’s leaving the dairy farm for the sophisticated Trinity College in Dublin. This is a coming-of-age story in that Debbie has been protected at the farm, with little city involvement. She’s intimidated by not only moving to university, but also navigating the big city. This is the story of her finding her place in the world, learning what other lifestyles there are other than dairy farming. As associated with moody Tumblr photo sets as it is with intergenerational politics, it’s a term usually reserved for use by older people condescending to younger people, and it encapsulates the tender and emotional worlds of Nealon’s characters perfectly.

What we now have created is a deep copy of the CUSTOMERS table and a new table, which has received all data from CUSTOMERS and is called CUSTOMERS_DEEP_COPY. The deep copy means that the table structure and data has been copied, as opposed to a shallow copy, which would copy the table structure only. This copied table is now an independent copy that can have a life cycle of its own with no changes or side effects originating from any operations performed on the CUSTOMERS table. A SELECT QUERY statement on this new table would generate the same results as shown in the previous table. Transient tables are non-permanent tables, but unlike temporary tables, transient tables exist until explicitly dropped and are visible to any user with the appropriate privileges. Transient tables have a lower level of data protection than permanent tables. Data in a transient table may be lost in the event of a system failure. Transient tables should only be used for data that can be recreated in the event that the data is lost. There’s a desire for her tortured experience to be unique to hers, when – as may of realise with age – it’s exceptionally common: "Great", she says when told she may have generalised anxiety. "It’s not just anxiety, it’s generalised too." The time travel configuration can also be changed at a later time by altering the database with ALTER: ALTER DATABASE temporary_databaseA local temporary table (also known as a volatile table) persists for the duration of the user session in which it was created and is not visible to other users. A temporary table's definition and contents are dropped at the end of the user session. Discover how Snowflake’s unique objects and features can be used to leverage universal modeling techniques through real-world examples and SQL recipes It is important to note that creating a new schema sets the current schema of the session to the newly created schema. The implication of this behavior is that any subsequent DDL commands such as CREATE TABLE would create the table under that new schema. This is like issuing the USE SCHEMA command to change the current schema. There's more… It would be too easy to compare Nealon’s debut to another young female Irish writer. Yes, that one. And maybe that one, too. But if those works zeroed in on the uncomfortable realities of being a young person, Snowflake subtly debunks the misconceptions around what it’s like to come of age today.
