A simple SQL query like the following: SELECT A, B FROM TBL1 WHERE A = 'a' faces an error ORA-01405: fetched column value is NULL Note in TBL1, A is defined as VARCHAR2(30) and B is NUMBER(4,2). My Pro*c version is Pro*C/C++: Release 11.2.0.3.0 And I am using GNU gcc family of compiler g++ version 2.95.3. Oracle documentation (http://docs.oracle.com/cd/A57673_01/DOC/api/doc/PC_22/ch03a.htm) states that if you SELECT or FETCH a null into a host variable that has no indicator, Oracle issues http://stackoverflow.com/questions/25565030/proc-code-handling-to-solve-ora-01405-fetched-column-value-is-null the following error message: ORA-01405: fetched column value is NULL One suggested remedy is: we can specify UNSAFE_NULL=YES to disable ORA-01405 message while running Pro*c but when I try to add that flag with proc command, it says, UNSAFE_NULL=YES allowed if MODE=ORACLE and DBMS=V7 or V8 Any other suggestions? c++ c oracle oracle11g oracle-pro-c share|improve this question edited Aug 29 '14 at 12:52 Mark J.

Bobak Aug 29 '14 at 12:44 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote Been years since I did any Pro*C, but I remember when I first came across this in an earlier version of Pro*C, and you had to use indicator variable to check if the value was NULL or not. That changed however when Oracle introduced the STRING datatype. I liked this so much I even started to TO_CHAR numbers and store them to STRING. See this from that document you linked to: STRING The STRING datatype is like the VARCHAR2 datatype, except that a STRING value is always null-terminated. On Input Oracle uses the specified length to limit the scan for the null terminator. If a null terminator is not found, Oracle generates an error. If you do not specify a length, Oracle assumes the maximum length of 2000 bytes. The minimu

New I changed library definition to address somewhere wrong and I still catch the same exception! Is there a parameter or something which I have to set before calling the function? oracle stored-procedures functions share|improve this question edited Aug 14 '12 at 15:54 asked Aug 14 '12 at 15:14 hmmftg 13819 Can you give me a stub .c prog that lets you reproduce this? –Philᵀᴹ Aug 14 '12 at 15:25 Sorry for asking but what do you mean by stub.c? –hmmftg Aug 14 '12 at 15:26 Stub.
