The Mid function returns a substring of
a string argument.
Returns: A string.
Parameters
- String
- Specifies the string whose substring is to be returned.
- StartIndex
- Specifies the one-indexed character of the string from which the substring starts. For example, if you specify a start index of 2 for the string Duluth, the first character of the substring would be u. You must specify a value greater than 1. If you specify a value greater than the length of the string, the function returns the empty string.
- Length
- Specifies the length of the substring to return. If you omit this parameter, the function returns the substring that starts at the character that StartIndex specifies and ends with the last character of the string. You cannot specify a negative length.
