Remarks

The RIGHT function extracts the rightmost characters from a string. This is useful for extracting suffixes, file extensions, or the end portion of identifiers. If the length exceeds the string length, the entire string is returned.

Examples

Extract the last four characters of a reference number as the check digits:

var schema = manager.LoadSchema("finance");
var transactions = schema["transactions"];

var query = new Query()
    .Select([ transactions["id"], new Expression("check_digits", new Right(transactions["reference"], 4)) ])
    .From(transactions);

var results = manager.Retrieve(query);
