Re: [SR-Users] sql_xquery return 1 on 0 rows?
Just to brainstorm: We may want to look into implementing something like the
old xpath or new shiny jpath (for json) for the xavps.
And if someone volunteer to write more xavp example code to explain them I
think we would make life easier for a lot of Kamailians.

Re: [SR-Users] sql_xquery return 1 on 0 rows?
Hello,
checking the presence of the xavp with the result is probably the way to
do it, the docs do not list different return code for no-result case.
Cheers,
Daniel

Re: [SR-Users] sql_xquery return 1 on 0 rows?
Hello,
sql_xquery() does not store anything inside $dbr(...), it stores the
result inside $xavp(...).
You have to use sql_query() to store inside $dbr().
Cheers,
Daniel

[SR-Users] sql_xquery return 1 on 0 rows?
Dear List...
kamcmd> version
kamailio 5.4.7 (x86_64/linux)
Strange issue found.
According to:
https://kamailio.org/docs/modules/5.4.x/modules/sqlops.html
I should get return value 2 if no rows returned:
$var(query) contains a query that does not match (number is not
assigned)
if (sql_xquery("impkam", "$var(query)", "assignedtn") == 1) {
if ($avp(debug) > 1) {
xlog("L_INFO", "$cfg(route): SQL Dump Result:
$var(assignedtn) ROWS: $dbr(assignedtn=>rows) \n");
}
do stuff with the assigned number
} else {
do stuff in case that number is not assigned
}
Log Output:
CHECK_ASSIGNED_TN: SQL Dump Result: 0 ROWS: 0
So the return value of the query was == 1 but the result contains no
rows. How can that be?
