Just replace '|' with new line, so the input looks like this: +:1:r 1:1 .
for the case. The first '1' indicates its reference count, and will be ignored for input tables. The man page has more description on how the reference count is used. For query in this example, use: ?:1:r 1: . This will list all tuples for the table 'r'. -- Yusheng ________________________________________ From: Hui Kang <ka...@us.ibm.com> Sent: Saturday, June 18, 2016 2:06 AM To: Yusheng Wang Cc: dev@openvswitch.org Subject: Re: [ovs-dev] [PATCH] OVN: initial patch of datalog engine Hi, Yusheng, When running the datalog test_interactive program, I have some difficulty in generating the output of the incremental change. Could you help to check at which step I did something wrong? ----------------------------------------------------------------------------- Step 1: Create a rule of joining table r(a) with an empty table as in the example root@test:~/ovs/tests# ./ovstest test-datalog run Input rules, e.g. R(a):r(a). use EOF as end R(a):r(a). EOF Input changes, e.g. +:1:tbl_name|1:f0:f1|. use +, -, ? for add, remove, or query. could input multiple tables. the number in table name line indicates number of tuples to follow. '|' stands for new line. use '.' to exit for query, field value could be empty. Step 2: I tried to insert one tuple to table r in order to see the change datalog will make to table R. Since table r has one field name as a, I input the following line and I got this error message +:1:r|1|. Error in format ------------------------------------------------------------------------------- Any idea? Thanks. - Hui _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
