SQL insert in rlm_expr

[Marius Booysen]

I am fairly new to Radius, so please forgive me if this question is very
basic.

I am using version 3.0.14 and I know you can use the sql module in rlm_expr
e.g
%{sql:SELECT.....WHERE...}

Now I am wondering if this is limited to select statements only or can I
insert a row into a custom table like this:

%{sql:INSERT INTO mytab (id) values (100)}

I tried this in a policy and the policy executes fine (debugging shows that
it is executing the insert) and returns ok, but the mytab table stays empty.

Am I doing something wrong or is it just not supported?

Thanks!
