<p>Dear OpenSIPS-users,</p>
<p><br>
</p>
<p>In the OpenSIPS database I have created some new tables, for my project. I can read from such tables successfully. For example, the instruction</p>
<p><br>
</p>
<p> <i>avp_db_query("select Value from GeneralConfigurations where Attribute = 'CallMaxDuration'", "$avp(CallMaxDuration)");</i></p>
<p><br>
</p>
<p>run and works very well. It put the right value in the apv!</p>
<p><br>
</p>
<p>However, when the following instruction is executed, it doesn't take any effect in the database:</p>
<p><br>
</p>
<p><i> avp_db_query("update GeneralConfigurations set Value = 'yes' where Attribute = 'Exists_Intercom_Call'", "$avp(UpdateResult)");</i></p>
<p><br>
</p>
<p>The log says:</p>
<p>-----------------------------------------------------------------------------------------------------------------------------------------------------------------------</p>
<p><br>
</p>
<p>Nov 3 11:32:52 [29114] DBG:avpops:ops_dbquery_avps: query [update GeneralConfigurations set Value = 'yes' where Attribute = 'Exists_Intercom_Call']<br>
Nov 3 11:32:52 [29114] DBG:avpops:db_query_avp: no result after query<br>
Nov 3 11:32:52 [29114] DBG:avpops:db_close_query: close avp query<br>
Nov 3 11:32:52 [29114] ERROR:db_sqlite:db_sqlite_free_result: <font color="#FF0000">
invalid parameter value</font></p>
<p><br>
</p>
<p>------------------------------------------------------------------------------------------------------------------------------------------------------------------------------</p>
<p><br>
</p>
<p>But the query UPDATE is correct, because I have already tested it directly in the database.</p>
<p><br>
</p>
<p>So, am I doing something wrong? What exactly does mean that error "invalid parameter value" in this case? Can I use UPDATE in an avp_db_query?</p>
<p><br>
</p>
<p>Any hint will be very helpful!</p>
<p><br>
</p>
<p>Best regards.<br>
