What is the method for creating temporary tables in SQL Server?

In SQL Server, temporary tables can be created using either of the following two methods:

1. Create a temporary table using the CREATE TABLE statement.
2. Establish a temporary table with columns and datatypes specified as needed.
3. Adding a “#” symbol before the table name indicates that a locally temporary table is being created. The temporary table is only valid within the current session and will be automatically deleted when the session ends.
4. Create a temporary table using the SELECT INTO statement.
5. Create a temporary table called #temp_table and select column1, column2, and other columns from the source_table.
6. The SELECT INTO statement can be used to create a temporary table from an existing table or query result set. Similarly, adding a # character in front of the table name indicates that a local temporary table is being created.

Temporary tables can be operated and queried like regular tables, regardless of the method used. After using a temporary table, you can manually delete it using the DROP TABLE statement, or wait for it to be automatically deleted when the session ends.
