try on your machine
This command is used to create a new table in a database with a specific name and column. Let's break down each part of the command:
create table: This is the syntax used to create a new table.${table_name}: This is a placeholder for the name you want to give to the table. You would replace${table_name}with the actual name you want to use.(${col} ${type}): This specifies the column name and its data type that you want to create in the table.${col}and${type}are placeholders for the actual column name and data type you want to use.partitioned by (${col} ${type}): This indicates that the table will be partitioned based on a specific column. It means that the data in the table will be physically divided based on the values in this column, which can improve query performance.lifecycle ${days}: This specifies the lifecycle of the table, in terms of the number of days it will be retained in the database.${days}is a placeholder for the actual number of days you want to set for the table's lifecycle.
In summary, this command is creating a new table with a specified name and column, partitioning the table based on a specific column, and defining a lifecycle for the table.
