InterSystems: The power behind what matters   

A scalar string function that returns a specified number of characters from the end (rightmost position) of a string expression.
{fn RIGHT(string-expression,count)}
string-expression A string expression, which can be the name of a column, a string literal, or the result of another scalar function, where the underlying data type can be represented as any character type (such as CHAR or VARCHAR).
count An integer that specifies the number of characters to return from the ending (rightmost) position of string-expression.
RIGHT returns count number of charactersfrom the end (rightmost position) of string-expression. RIGHT returnsNULL if passed a NULL value for either argument.
RIGHT can only be used as an ODBC scalar function (withthe curly brace syntax).
The following example returns the two rightmost characters of each name in the Sample.Person table:
SELECT Name,{fn RIGHT(Name,2)}AS MiddleInitial
     FROM Sample.Person
The following embedded SQL example shows how RIGHT handlesa count that is longer than the string itself:
   &sql(SELECT Name,{fn RIGHT(Name,40)}
     INTO :a,:b
     FROM Sample.Person)
   IF SQLCODE'=0 {
     WRITE !,"Error code ",SQLCODE }
   ELSE {
     WRITE !,a,"=original",!,b,"=RIGHT 40" }
No padding is performed.
