• SET name value – Sets the variable name to the value value. Variable names and values cannot contain spaces.
• GET name – Prints out the value of the variable name, or NULL if that variable is not set.
• UNSET name – Unsets the variable name, making it just like that variable was never set.

Transaction Commands

Database supports transactions with commands:

• BEGIN – Opens a new transaction block. Transaction blocks can be nested; a BEGIN can be issued inside of an existing block.
• ROLLBACK – Undoes all of the commands issued in the most recent transaction block, and closes the block. Prints nothing if successful, or prints NO TRANSACTION if no transaction is in progress.
• COMMIT – Closes all open transaction blocks, permanently applying the changes made in them. Prints nothing if successful, or prints NO TRANSACTION if no transaction is in progress.
