  2. Create a temporary table named “table_name” with columns “column1” and “column2” of specified data types.
  3. For example, create a temporary table named temp_table:
  4. Create a temporary table called “temp_table” with columns “id” of type INT and “name” of type VARCHAR(50).

  6. Add values into a table with specified columns.
  7. For example, inserting a record into the temporary table temp_table.
  8. Add a record to the temporary table with the ID of 1 and the name ‘John’.
  9. Retrieve data from a temporary table using the SELECT statement. The syntax is as follows:
  10. Retrieve data from the specified columns in the table.
  11. For example, retrieve all data from the temporary table temp_table.
  12. Retrieve the id and name columns from the temporary table.
  13. The temporary table will be deleted automatically when the conversation ends, no manual deletion is required.

Please take note:

  1. Temporary tables are only visible within the current database session and cannot be accessed by other sessions.
  2. You can perform all standard SQL operations in a temporary table, such as inserting, updating, deleting, and querying data.
  3. Database objects such as indexes, triggers, and constraints can be created in temporary tables.
  4. You can use the SHOW TABLES command to view the temporary tables in the current session.
