OK people, No need for anyone to respond on this topic, as I have solved the problem. If you are interested, the problem occurred because my commercial JDBC driver does not support the JDBC 2.0 API (but rather is still at JDBC 1.2). In other words, it cannot support advanced data types such as Array objects. Alan |

If i come across a situation like this my solution is. Create a data structure ( A Normal class ) to hold the details of a single row. ( For example if it's a emp table create a emp Class ) For each row in the RecordSet Instantiate & set the value of all members in this class & add it ... |
I need to get rows of data from the database and place in an Arraylist. I'm not sure if an ArrayList is the right choice, I need to get my ArrayList and call the Column names to place the out put in a sorted order to print to a file for another system to process so it is imperative that data ... |
We can use getxxx to get the resultset's individual feild value, how can we use an array object to store a record (row) value? For example: resultset has 5 columns/fields and they have different data type. Can we do this: while (rs.next()) Object[][][][][]= { {rs.getObject(1)}, {rs.getObject(2)},...,{rs.getObject(50} } I think my syntax is wrong, can anyone give me some helps? Thanks! Mindy ... |

Hi Im looking for the fastest, most efficient way to parse a resultSet into a 2D array. Due to the structure of my program a 2D array is the preferable data structure, i dont want to use a map or a list. Could anyone please point me to a simple way to parse a resultSet into a 2D array ? Thanks ... |

okay so in my servlet i do a query, get a resultset, and pass it to a bean, then forward to a jsp page. well in the bean it turns it into a multidimentional array, and then the jsp page grabs it and does a few loops and pulls the information out. this is what i was intending my code to ... |

Or if someone knows a better way of goign about this please let me know. The main objective is to populate this table with objects containing each of of the above ... |
out.println("End"); At the client side i copied the whole resultset in a 2-D string array as follows: String[][] a = new String[25][1000]; int count=0; String b; loop1: for(i=0;i<35;i++) { count++; for(j=0;j<7;j++) { b=in.readLine(); if(b.equals("End")) { break loop1; } a[j]=b; } } I took a variable 'count' to count the total no. of records in the resultset. Now at the client side ... |
You can save the elements in a 2D array by iteration over the ResultSet's rows and columns and at the same time iterating over the arrays rows and columns. Nested loops. A better way would be to put the results in a 1D Collection (List, probably) of item of a class that you define that represents a row. |
