In SQL, you can convert a string to a number using either the CAST function or the CONVERT function.

  1. Utilize the CAST function:
  2. Choose the number 123 and store it as an integer in a variable called ‘num’.
  3. Use the CONVERT function:
  4. We want ‘123’ to be converted into an integer value and stored as ‘num’.

Caution: When converting a string to a number, make sure the string only contains numbers to avoid errors.
