Weird issues with Oracle Max Functions

The Oracle Max function generates a strange problem when writing another stored procedure, the following SQL statement www.2cto.com SELECT MAX (RE_DATE) INTO V_RE_DATE FROM T_RECORDINGWHERE ID = '20140901' is used'
It is reasonable to say that the query result based on this condition should be sqlcode = 1403, But it is strange that the following SQL EXCEPTION cannot be caught: EXCEPTION WHEN NO_DATA_FOUND THEN NULL; WHEN OTHERS THEN ERR_CODE: =-2000; ERR_MSG: = SQLERRM; RETURN; no error is returned during execution. Check the V_RE_DATE value by executing the command and the value is blank, if the value is null, The sqlcode = 1405 exception should also be reported. But the oracle execution engine has not reported any error. What is the problem? Write down this situation first today, I will study it later.
