I am invoking a stored proc from .NET app. The proc returns an out parameter of type Varchar2. To fet ch the out parameter I am passing the parameter to the command as OracleParameter:
parm12 = new OracleParameter("testkey"
, OracleDbType.Varchar2
, out2
, ParameterDirection.Output);
When I execute the proc I am receiving an error
PL/SQL: numeric or value error: character string buffer too small.
Found the answer.
For the OUT parameter i declared the size to max of varchar - 32767 and it started to work.
To simplify, the stored proc returns a parameter OUT of type VARCHAR2. But to consume that output from .NET i was passing VARCHAR2 without any size. So the buffer space allocated to recieve the reurn value was 0 bytes. When the proc returns the value more than allocated buffer which is 0 bytes it errors out.
So i specified the max of VARCHAR2-32767 in the C# code and it started to work :).
In your code out2 is the argument which specifies the length of the parameter. So check the value in that variable, because apparently it is not long enough for procedure's output.
