Creating Temporary Tables in Snowflake
Temporary tables are a great way to store data temporarily in Snowflake. They are useful for storing data that is only needed for a short period of time, such as data that is used for a specific analysis or report. Temporary tables are also useful for testing out queries before running them on permanent tables.
Creating Temporary Tables in Snowflake
Creating a temporary table in Snowflake is easy. All you need to do is use the CREATE TEMPORARY TABLE statement. This statement takes the same arguments as the CREATE TABLE statement, but adds the TEMPORARY keyword. For example, the following statement creates a temporary table called “my_temp_table”:
CREATE TEMPORARY TABLE my_temp_table (
id INT,
name VARCHAR(255)
);
Once the table is created, you can use it just like any other table. You can insert data into it, query it, and so on. When you’re done with the table, you can drop it using the DROP TABLE statement.
Examples of Using Temporary Tables in Snowflake
To illustrate how to use temporary tables in Snowflake, let’s look at a few examples. In the first example, we’ll create a temporary table and insert some data into it.
CREATE TEMPORARY TABLE my_temp_table (
id INT,
name VARCHAR(255)
);
INSERT INTO my_temp_table (id, name)
VALUES (1, 'John'), (2, 'Jane'), (3, 'Bob');
In the second example, we’ll query the temporary table we just created.
SELECT * FROM my_temp_table;
This query will return the following results:
id name
1 John
2 Jane
3 Bob

It’s important to note that temporary tables are specific to Snowflake. Other databases, such as MySQL and PostgreSQL, have their own ways of creating temporary tables. It’s important to check the documentation for the database you’re using to make sure you’re using the correct syntax.
