Java PreparedStatement对表的评论

Question

I'm familiar with using java prepared statements to insert/update on a table. In oracle you can add a comment on a table, how would I use a preparedstatement to do that?

This was my initial attempt with no luck;

PreparedStatement stmt = con.prepareStatement("comment on table my_table is q'[?]'");
stmt.setString(1, description);
stmt.executeUpdate();

Answer 1

You can use system Oracle table and set comment there with PreparedStatement , like this:

PreparedStatement stmt = con.prepareStatement(
    "UPDATE user_tab_comments SET comments = ? WHERE table_name = 'my_table'");

Or try to use simple statement:

String commentOnTableSQL = String.format("COMMENT ON TABLE my_table is '%s'", comment);
Statement statement = dbConnection.createStatement();
statement.execute(commentOnTableSQL);
