To convert a string to an int, the function is . . . . . . . .

Solution (By Examveda Team)

This question asks about how to convert a string (a piece of text) into a whole number (an integer) in MySQL.

Let's break down the options:

Option A: INET_ATON(): This function actually converts an IP address (like 192.168.1.1) into a numeric representation. It's not for general string-to-integer conversion.

Option B: INET_NTOA(): This function does the opposite of INET_ATON(), converting a numeric representation of an IP address back into the familiar dot-separated format. It's not for converting strings to integers.

Option C: INET_ITOS(): This option doesn't exist in MySQL.

Option D: INET_STOI(): This option doesn't exist in MySQL.

The answer: None of the above options are used to convert a string to an integer in MySQL. MySQL uses the CAST() function to achieve this. For example, to convert a string called '123' to an integer, you would use:

`SELECT CAST('123' AS UNSIGNED);`

This would return the integer value 123.
