<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have a DB2 stored proc that takes OUT params and returns a CURSOR so that our Erlang module can get a List of records using the odbc module.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We invoke the stored proc using the code:<o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">Params = [{{sql_varchar, 40}, out, [[]]},{{sql_varchar, 40}, out, [[]]}].<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">{selected, Results} = odbc:param_query(Ref,"call SP_NAME(?,?)",Params).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal">However, when we execute the stored proc, the OUT params get set with a value that indicates that the proc execution is successful, but no records are fetched from the cursor into the list.<span style="color:#1F497D"> The output of param_query
is :</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">{executed,2,[{"00000","NO ERROR"}]}</span><span style="color:#1F497D"><o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can you suggest what needs to be done to read the OUT params as well as the records from the stored proc results?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks<span style="color:#1F497D">,</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">Yash<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
