I'm getting the below mentioned error when we call stored procedure named as Fetch_Analysis_Results from OCI program. Below attached is the error message, OCI program,stored procedure.

Error Message
=============
executing fetch() for 1981 time
dbFetchOneRow(): Executing stored procedure
dbFetchOneRow(): Could not execute statment
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at line 1

B: Text of OCI program
======================
int dbFetchOneRow(AlarmInfo_t *alarmInfo)
{

text *plSqlProcedure = (text *)"BEGIN
FETCH_ANALYSIS_RESULT(:nodeType, :nodeName,:paramName, :severity, :thresholdValue, :functionType, :timeperiod, :varianceThreshold, :thresholdOperation, :thresholdFrequency, :profileType, :profileValue, :thresholdRate, :startTime, :endTime, :value);
END;";

check local variable declaration. normally you will get this error when you try to fetch or assign value into variable of less length than fetch column length.

example:
ley us say, you declare variable a of length 2.
if you fetch value into that variable of lengh more than that results error.

declare
a varchar2(2);
begin
select b into a from table;
-- if b is of length 3, it will result in error.

end;
