Another problem is bothering me.
I am trying to query a batch of values from mysql.
For example,In “The Data Retrieval page”,I am using the sql statement, something like this “select id from table”. Actually this statement would get a result set,but only the first record is shown, the following records are missing.

I figure out this could be solved if more devices are configured,with specified sql statements are written. But this does not seem elegant,somehow
