Answer:
The above query gives an error.
Explanation:
- The query gives an error because is not the correct syntax of the select or inserts query.
- The syntax of the select query is as follows: "select Attributes_1_name, Attributes_2_name,...., Attributes_n_name from table_name;".
- The syntax of the insert query is : "insert into table_name (column_1_name, column_2_name,...,column_n_name) values (column_1_value, column_2_value,...,column_n_value);".
- The syntax of the insert and select query is : "insert into table_name (select Attributes_1_name, Attributes_2_name,...., Attributes_n_name from table_name);".
- But the above query does not satisfy any property which is defined above. Hence it gives a compile-time error.
