Ordinal Function

[Terry Coccoli]

Has anyone created a user function to return the ordinal position based
on numeric input?

In other words, f(1) returns 'st', f(2) returns 'nd', f(3) returns
'rd', etc.

Check out the format mask of the to_char function in the sql reference manual.
Other than that (if the format mask is lacking), visit http://asktom.oracle.com
You'll probably find code there.

This should work over all integers...

CREATE OR REPLACE
FUNCTION F(N IN NUMBER) RETURN VARCHAR2 IS
X_RESULT VARCHAR2(2);
BEGIN
IF ABS(N) BETWEEN 10 AND 20 THEN
RETURN 'th';
END IF;
SELECT DECODE(MOD(ABS( N),10),1,'st', 2, 'nd', 3, 'rd', 'th')
INTO X_RESULT FROM DUAL;
RETURN X_RESULT;

END;

Terry, Ordinal position of what? A varchar2 array? The ASCII value?
