From source file:Main.java

    st.executeUpdate("insert into survey (id,name ) values (1,'nameValue')");

    ResultSet indexInformation = null;
    DatabaseMetaData meta = conn.getMetaData();

    // The '_' character represents any single character.
    // The '%' character represents any sequence of zero
    // or more characters.
    indexInformation = meta.getIndexInfo(conn.getCatalog(), null, "survey", true, true);
