How can I determine if the column name exist in the ResultSet?
Use the ResultSetMetaData class.
public static boolean hasColumn(ResultSet rs, String columnName) throws SQLException { ResultSetMetaData rsmd = rs.getMetaData(); int columns = rsmd.getColumnCount(); for (int x = 1; x <= columns; x++) { if (columnName.equals(rsmd.getColumnName(x))) { return true; } } return false;}The thing I don't understand is why this function would ever be needed. The query or stored procedure being executed should have known results. The columns of the query should be known. Needing a function like this may be a sign that there is a design problem somewhere.
