Answer: getfenv() is a type of function. Particually a envirotment function. for a lua coding.

Explanation: What this does it goes thourgh line of code in a particular order.

This means. getfenv is used to get the current environment of a function. It returns a table of all the things that function has access to. You can also set the environment of a function to another environment.

Forgot to include examples of where this could be used. Although not very common uses, there are some. In the past Script Builders used getfenv to get the environment of a script, and setfenv to set the environment of a created script’s environment to a fake environment, so they couldn’t affect the real one. They could also inject custom global functions.

Not entirely sure if this uses getfenv or setfenv, but the use in Crazyman32’s AeroGameFramework is making the environment of each module have access to other modules without having to require them, and having access to remotes without having to directly reference them.

What is the output of the following query? SELECT INSERT ('Knowledgeable', 5, 6, 'SUPER');

Scrat [10]

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.
