In Snowflake, you can use the “GET_DDL” function to retrieve the SQL script used to create a specific database, schema, table, view, materialized view, or other database object. This can be useful if you need to recreate the object, or if you want to review its schema and properties.
Here’s an example code snippet that demonstrates how to use the “GET_DDL” function to retrieve the SQL script used to create a table:
SELECT GET_DDL('TABLE', '<table_name>');
Replace <table_name> with the name of the table that you want to retrieve the SQL script for. Note that you need to have the necessary privileges to execute this command.
The output of the “GET_DDL” function will include the full SQL script used to create the object, including column definitions, constraints, indexes, and other properties. Here’s an example output:
CREATE TABLE my_table (
id INT,
name VARCHAR(50),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP()
) COMMENT = 'This is my table' CLUSTER BY (id) ORDER BY (name);
You can copy and paste the SQL script from the output of the “GET_DDL” function to recreate the object or modify its schema. Note that you might need to modify the SQL script to adjust certain properties (e.g., changing the table name or column data types).
