The value will be output only if the length of the string is equal to the specified length; otherwise a null is returned. If the length specified is 0, the length of the data is returned. If a maximum (m) length is specified, then n represents the minimum length and the value will be output only if the length of the string is equal to or greater than the minimum value and equal to or less than the maximum value. Otherwise a null is returned. |

If specified, the value will be output only if the length of the string is equal to or greater than the minimum specification (n) and equal to or less than m. Otherwise a null is returned. |
