You can use this API to execute standard queries and most DDL and DML statements.

Still, the right fit for any specific problem depends on many parameters.The Snowflake SQL API is a REST API that you can use to access and update data in a Snowflake database. If we want a balance between space-saving and performance, we can use the starflake schema. It may be the right choice in situations where disk space is more important than performance. You can execute this SQL either from SnowSQL or from Snowflake web console.The snowflake schema is often used in data modeling. We're thrilled to announce that Snowflake's annual user conference is back in person this year! The live event-our largest user conference to date-will take place June 13-16 in Las Vegas.How do I transfer parquet from S3 to Snowflake? To load a CSV/Avro/Parquet file from Amazon S3 bucket into the Snowflake table, you need to use the COPY INTO SQL. This innovative approach to querying allows users to store JSON documents in a relational table using a new data type (VARIANT) that is optimized automatically in the background for columnar and MPP access.Your Guide to Snowflake Summit 2022, June 13-16. Using Snowflake, users can access JSON data with queries in SQL, and easily join it to traditional tabular data. We partition the rows based on ID column, and then we select only first rows by using QUALIFY and ROW_NUMBER () = 1. On PostgreSQL, it's possible to use the following query to list only one row with same ID: SELECT DISTINCT ON (id) * FROM test_table On Snowflake, we can use QUALIFY clause and ROW_NUMBER () function to produce the same result. create or replace table vartab (n number (2), v variant.
So, when the column is passed as an argument and the data type of that column is Variant then the explicit cast is not required. the TYPEOF function takes a Variant as input and outputs the type of the value stored. Next Steps Check out other Snowflake resources:TYPEOF function reports the type of value stored in a Variant column i.e.
On-premises, you have absolute control and a more predictable cost. With the cloud comes ease-of-management, great performance and elastic scalability. High Data redundancy.Choosing between Snowflake or an on-premises SQL Server essentially boils down to the choice if you want to move to the cloud or not. Better for small data warehouse/data mart. Work best in any data warehouse/ data mart. A snowflake schema is an extension of the star schema. Star schema is relational schema which is follow the concept of facts and dimensions.
