I want to store the rows of an sql query resultset in a vector.
I add the values into it in a loop.
Here is my code:
You are missing the declaration of row_container.
I assume it's
String[] row_container = new String[fields.length];
and is placed outside the while loop.
while (SQLResultSet.next()) {
... fill row_container ...
buffer.addElement(row_container); // adding the string array to the vector
In the row_container I store in each iteration one resultset row.
The problem is, that it seems to me, that the addElement method adds
the row_container to the end of the vector and then changes the value
of all its previous instances.
No. What happens is that you add the *same* array to the Vector multiple
times, and you update that array in your loop.
Try instead to move the declaration of row_container inside the while-loop.
This will ensure that you create a new array for each row.
It fixed the problem! Thx!
