For details on all the built-in functions, such as number and types of arguments, see the SQL Language manual.

SELECT                
max(print_date,inv_date)
FROM Temp;
MAX only takes one argument. (Most aggregate functions only take one argument.)
You probably want the GREATEST function, not MAX.
