从Java调用postgresql函数

Question

I have very strange issue. I design one function which is inserting values into postgresql table. But when I try to call that function from java at that time it seems like did not insert. Even I am not getting error as well. My code is below.

String query = "{call postgres.addToLog(?,?,?,?,?,?,?)}";

    try{

        CallableStatement ps = getPostgresConfiguratoin().prepareCall(query);

        ps.setTimestamp(1, new Timestamp(new java.util.Date().getTime()));
        ps.setInt(2, 705);
        ps.setInt(3, 1);
        ps.setInt(4, 1);
        ps.setString(5, "192.168.2.101");
        ps.setString(6, null);
        ps.setString(7, query);
        ps.executeUpdate();
        ps.close();
    }catch(Exception ex){

    }

Is there anything wrong with my call?

Answer 1

I found in logs that my function insert query has one column name which has wrong spelling so my insert query never insert anything. After furthermore research I found out that as best practice to provide exception handling into PL-SQL as well. I provide Exception handler into my PL-SQL block and it return error which I can see on my Java program side as well.
