Answer 1

The script contains SQL commands that are syntactically incorrect, missing the FROM clause in the first SELECT statement, which would result in no output due to the error in the code.

Step-by-step explanation:

The given code segment is from a SQL program and pertains to a database operation. Unfortunately, the SQL code provided in the question seems to be incomplete and syntactically incorrect, as the FROM clause in the first SELECT statement is missing a table name. The code also does not specify the joining condition for the tables, which indicates that the question might include a typo or error.

Assuming the provided code were corrected with proper syntax and table names, if the code intended to perform a join operation without specifying a join condition, the result would be a Cartesian product. However, since the syntax is incorrect and the intention is not clear due to the missing information, the code in its current form would result in an error and therefore produce no output.
