thanks for response Yoav,
i knew message was off topic, but did not realize that such messages should
be marked such. Thanks for informing me.
your answer to my question is what i would have guessed, but cannot find
anything to that effect in Java Docs on ResultSet interface.
to complicate the matter, i have some code as follows, which works fine
(which is why i posted question in first place, because i would have guessed
what you said):
for (i=0; i < parentTable.size(); i++) {
// note: this stmt executed repeatedly in for loop
rset4 = stmt.executeQuery ("select field1, field2, fieldN from
schema.tblsubj3 where field4 = " + parentTable.get(i) + " order by field1");
if (rset4.next()) {
....
Note that the ResultSet interface, rset4, is re-used repeatedly for changing
values in the array "parentTable", altering only the value for the WHERE
condition in each iteration of the loop.
notes:
rset4 is initialized outside the try-catch block as follows:
ResultSet rset4 = null;
the array parentTable is initialized as follows:
ArrayList parentTable = new ArrayList();
I am not asking a question this time round. Just thought i would share
this info. Also wondering if this use of ResultSet could generate
un-reliable results.
