I am not sure if there is any such function in 9i . But you can definnitely
accomplish this by writing your own function something like
function isNum(a varchar2) returns boolean is
begin
b := tonumber(a);
result = true;
return result;
exception
when (numer or value error) -- get proper exception
result=false
return result;
end;
same can be done for isDate as well.

> I am investigating an effort to move our product into Oracle from SQL
Server. Came across the function isnumeric, isdate in SQL Server that
returns true or false if the input string is in a form that can be converted
into a numeric or date type. searched in oracle help and am not able to find
an equivalent. Is there any equivalent form of these functions in Oracle??
